What Patriotism means to me Essay

Do you believe in the love for your country? All the soldiers and heroes that are out there in the world fighting for our freedom? The respect and the courage that you may have. Patriotism is like an infection that travels around from one body to another and you can’t cure it with any medication. To me patriotism basically means the love and care for one’s country. Although it may have other definitions, the real and main one is â€Å"the love and devotion for your country†. Being patriotic means not only wearing the flag as a pin, putting it up on your yard or saying the national anthem like most people do, It really means caring for the soldiers and everyone that helps this country be free, also to give out your love and potential to your country. There are a lot of examples and symbols that patriotism can mean to me or to anyone in this world. For example, September 11, the United States flag, the Statue of Liberty and many more are symbols of patriotism. I think that patriotism has grown more since 9/11 the day that changed the world, and that it is going to keep on growing more and more throughout the years to come. A married couple is like patriotism because they can’t decide on the right choice or also like each other about how they are. Martin Luther King Jr. had the courage to lead a movement against segregation he also had the courage to tell us what was wrong and what we did right. To me that is real patriotism because he was willing to fight for our country and love it equally among others. â€Å"If we love our country, we should also love our countrymen† is a famous quote by Ronald Reagan that I think describes patriotism because it simply means love one another equally. So to me patriotism means the love for your county, it also means many other different things to one another. Remember you can be patriotic if you love and respect your country by just basically caring.

Low Carbon Emission Family Hatchback Development Engineering Essay

In this quickly developing universe, the chief menace that is being faced is on fossil fuel. As every twelvemonth base on balls by, the sum of fuels used are traveling up the grade of the old old ages. If this rate keeps increasing, the dodo fuels will be wholly depleted to a province that these fossil fuels will merely be known in names and due to the increased usage of these fuels have led to the all sorts of pollution. In the recent survey, it was proved that automotive Fieldss are one with the greater ingestion and fouling rate compared to other Fieldss utilizing fossil fuels. And, one of those pollution jeopardies is addition in C footmark, which is the entire sum nursery gases produced. In order to confront the approaching menace, a new construct has been developed which would cut down the ingestion of fossil fuels and pollution jeopardies. A construct of an electric auto with lower limit or zero emanation and eco friendly characteristics accommodating to the nature protection is to be developed. 1.0 Purposes: To develop, a construct on a household hatch back vehicle with low C emanation which is powered by electricity and designed for an urban thrust rhythm with aid of quality map deployment ( QFD ) 1.1 Aim: To make proficient research in order to go cognizant of current developments in the market ; To fix a specification for a low C vehicle ; To develop several constructs ; To choose one construct utilizing QFD ; To fix a Gantt chart for the construct development stage of the undertaking. 1.3 SPECIFICATIONS OF THE VEHICLE: Table 1.3.1 is the Final specification of the LCV. Further study will explicate how these specifications were finalised. Length 3650mm Width 1550mm Height 1450mm Wheelbase 2650mm Minimum land clearance 170mm Seating capacity 5 people Kerb weight 1200kg Max loaded weight 1550kg Battery Lithium ion, 1000 rhythms Rated power 80kW Maximum torsion 448Nm Scope 120 stat mis minimum under normal urban conditions Human body frame Aluminium honey comb1.0 Conceptual Approach:QFD for Electric Vehicle:Table 1.1.1 is the QFD of the whole vehicle. The relation between Controllable parametric quantities and Customers & A ; Stake holders demands has be rated consequently, where 9-strongest, 3-moderate, 1-weak, and 0-no relation. This gives an thought on which governable parametric quantity we will hold to work more. The parametric quantities Battery ( 342 ) , Energy Storage Capacity ( 268 ) , Drive Motor ( 231 ) , Wear Resistance ( 239 ) , Price ( 303 ) shows maximal absolute importance, hence, choice process will be carried on, while giving maximal precedence to these parametric quantities.1.2 Fish Bone:The Fish Bone diagram shows a mode in which over aims will be achieved.Gantt chart of Concept Phase:Practically talking, Concept stage may take 2 to 3 old ages to finish. Chart 1.2.1 is our basic Concept Phase Gantt Chart demoing how a construct of a undertaking is developed ; if we were suppose to make a existent paradigm.1.4 Gantt chart of the Group Time Plan:Chart 1.4.1 shows clip planning of the group to execute different undertakings by group members. Therefore, from the Gantt chart now we know that which undertakings are over lapping the other undertakings ( blue in coloring material ) , and which undertakings start at the terminal of peculiar undertakings ( ruddy in coloring material ) .2.0 Batteries:Batteries are one of the most of import things, when it comes to an electric vehicle, as they are merely beginning of energy. Hence, choice of proper batteries plays an of import function for the operation of all the systems in an electric vehicle. This subdivision will cover some thoughts, which were used for choice of our batteries.2.1 Selection Procedure:Basic thing to get down with was to look into the demands, harmonizing to the market needs. Table 2.1.1 shows demands of EV batteries depending on different features and parametric quantities, adopted by USABC ( United States Advanced Battery Consortium ) . Battery Requirements as per USABC: Table 2.1.1 ( Anderman, Fritz, & A ; MacArthur, 2000 ) In our instance we will be sing demands related to long term. Further choice process will be more or less based on these demands.2.2 Available Electric Vehicle Batteries:A. Nickel Metal Hydride:Nickel Metal Hydride batteries passed assorted bench trials and were best among other campaigners for electric vehicle batteries. They were about capable of giving a calendar life of about 10 old ages. But disadvantages of utilizing Nickel Metal Hydride was that they are holding really low specific energy 60 to 80Wh/kg and therefore a lower scope for the vehicle to run in individual charge. For acquiring higher driving range the size of the batteries will hold to be increased and finally the weight besides increases.B. Lithium ion:And where the Nickel Metal Hydride batteries were neglecting Lithium ion passed, hence they were with every good belongingss of Nickel Metal Hydride and some more advantages. Lithium ion became more suited option to be used for electric vehicle batteries and as they have specific energy runing up to 450Wh/kg and better specific power. Most of the present and approaching electric vehicles are utilizing Lithium ion engineering.C. Lithium Polymer:Lithium polymer shows the potency of being cheaper than Lithium ion and Nickel Metal Hydrides batteries as cost of active stuffs is low in its instance. Besides holding higher specific energy about 650Wh/kg. But, still the procedure of fabricating these batteries is really complicated along with high cost electrolyte. Besides the working temperatures of these batteries restrict them from being a better option ( Delucchi & A ; Lipman, 2001 ) . Hence, the most executable option is the Lithium ion ( Table 2.2.1 ) . Features Nickel Metal Hydride Lithium Ion Lithium Polymer Specific Energy ( Wh/kg ) 60 to 80 150 to 450 Up to 650 Specific Power ( W/kg ) 150 to 200 150 to 800 300 Cycles ( 100 % DoD to 80 % of initial capacity ) 600 600 to 1000 200 to 600 Nominal Capacity ( Ah ) 90 100 to 180 50 to 120 Table 2.2.1 Characteristics Table ( Anderman, Fritz, & A ; MacArthur, 2000 )2.3 Selected Lithium Ion:QFD chart for batteries:Chart 2.3.1 Battery QFDOur battery Requirements and QFD chart gives a clear thought that Lithium ion battery is better than Nickel metal Hydride and Lithium polymer. Besides, from the QFD chart it is really much clear that, Battery Size ( 291 ) , Product Life ( 156 ) , Price ( 116 ) , Durability ( 115 ) , and Charging Speed ( 105 ) , have maximum absolute importance and comparative importance. Hence, for make up one's minding the concluding specifications of the batteries these parametric quantities will be given more importance as compared to others.2.4 Trade Offs Among Different Lithium Ion Battery Technologies:Lithium ion itself has many different types of discrepancies or different battery engineerings in it, therefore, farther attack is working on more specific restraints of the batteries. Table 2.4.1 ( Dinger & A ; Martin, 2010 )Safety:Most of import factor for EV batteries is the safety. Chemical reactions taking topographic point inside the batteries, while they are working or because of soaking consequences in high temperatures, which may ensue in fire. Table 2.4.1 shows, Lithium Nickel Cobalt Aluminium ( NCA ) has least safety features, whereas Lithium Nickel Manganese Cobalt ( NMC ) and Lithium Manganese Spinel ( LMO ) have moderate safety features and, Lithium Titanate ( LTO ) and Lithium Iron Phosphate ( LFP ) have highest safety characters.Life Span:Life span can be considered in two ways one figure of times batteries being to the full charged and dispatch boulder clay it is degraded to 80 % of its to the full charged original capacity and 2nd figure of old ages battery can be used.Performance:Performance in instance of battery is fundamentally how good the battery will execute in different climatic conditions.Specific Energy:Specific Energy is capacity for hi ve awaying energy per kg of weight. Gasoline has about 100 times more than that of the batteries. Hence, specific energy can besides be make up one's minding factor for size and weight of the batteries. Higher specific energy can ensue in low weight and smaller size of the batteries.Specific Power:Specific Power is the sum of power delivered per kg of mass. Specific is less of import as compared to specific energy in electric vehicles.Cost:As for now, the Li ion battery packs has cost estimations is between ?700 to ?850 per KWh, but with addition in technological development and competition among different makers, the fabrication costs of the batteries may diminish. The mark shown by USABC is ?250 per KWh by 2020, but someway Nissan is already claiming of supplying battery battalions at same figures with Nissan Leaf. So cost factor is likely to toss off really shortly.Which is better?LTO and LFP do hold really less safety jobs, but when it comes to specific energy they fall behind. And NCA is cost effectual, with higher specific energy, specific power and life span, but lags really much behind in safety. LMO has all the factors average every bit compared to others and short life span. Therefore, sing the demands ( Table 2.1.1 ) , Characteristics Table ( Table 2.2.1 ) , QFD ( chart 2.3.1 ) and all the factors, NMC is the most suited Lithium ion battery engineering. They have moderate safety characteristics, but this can be overcome by utilizing proper battery shell, chilling system and temperature monitoring devices, in sensible cost scope ( Anderman, Fritz, & A ; MacArthur, 2000 ) ( Dinger & A ; Martin, 2010 ) ( Delucchi & A ; Lipman, 2001 ) .2.5 Battery Manufacturers:Before specifying our concluding battery specifications looking for Battery makers and battery constellations these makers have, is a good thought. Industries have their ain R & A ; D sectors, and they welcome the demands of the client. Below are some makers who can supply us with Lithium-ion bat teries for our Electric Vehicle.China:J & A ; A EEMB LT EnergyJapan:Automotive Energy Supply Corporation GS Yuasa Corporation ( Momentum Technologies LLC, 1995-2010 )2.6 Battery Specifications:Our choice process therefore, leads us to battery specifications which will carry through our demands. Table 2.6.1 shows our approximative battery specifications. This may alter in footings of size, weight and cost, or even chemical belongingss depending on the makers. Specific Energy 200Wh/kg Specific Power 550Wh/kg Cycles 1000 Rated Capacity 100-180 Ah Nominal Voltage 3.7 V Charging Time 3 to 6 hours and 30 mins for rapid bear downing Weight 90x67x220 ( millimeter ) Dimension 150kg approx Cost 250 to ?300 per kWh / ?7500 to ?9000 per battery battalion2.7 High Voltage Electrical Distribution System:Electrical Loads in an car can split into two classs – propulsion and non-propulsion. Propulsion burden chiefly consists of motor and/or generator and Non-propulsion tonss include warmers, lamps, power Windowss etc. Maximal power is required for the propulsion loads which can be up to 100KW. Table 2.7.1 gives an approximative thought for power distribution in our instance.ComponentsPower Input ( kilowatt )Electric Motor 80 HVAC 8 Non-propulsion tonss 3 Entire 91 Table 2.7.1 ( Automotive Handbook, 2007 ) The electric vehicle has power coachs at different electromotive forces runing from lower to higher values and can be every bit high as 300 Vs. Hence, proper power direction and distribution system will be adopted in order to run into the demands of our vehicle constituents ( Fig 2.7.2 ) . Generic Automotive Power/Energy Management and Distribution system ( Shen, Masrur, Garg, & A ; Monroe, 2003 )3.0 MOTORS AND POWER ELECTRONICS3.1 Working rule of motors ( Leitman & A ; Brant, 2009 ) : When electric potency is applied, the twists generate the magnetic Fieldss which cause the armature to revolve and thereby, generate power. The efficiency of the electric motor ranges from 85 to 98 % .3.2 Present twenty-four hours EV ‘s:Electron volt Type OF MOTOR RATED POWER RATED TORQUE Nissan foliage AC lasting magnet synchronal motor 80 kilowatt 280Nm Mitsubishi iMiev AC lasting magnet synchronal motor 47kW 180Nm Subaru Stella AC lasting magnet synchronal motor 47kW 185Nm Thinkcity 3-phase asynchronous 34kW 140Nm 3.3 Propulsion system design ( Larminie & A ; John, 2003 ) : Constraints Variables Maximum speed Rolling opposition Maximal per centum class Aerodynamic drag co-efficient Initial acceleration Wheel radius Rated speed on a given incline Vehicle mass Maximum gradability Percentage class3.4 Advantages of electric motors over IC engines:Full torsion at low velocities Instantaneous power evaluation is about 2 to 3 times the rated power of motor Excellent acceleration with a nominally rated motor 3.5 Types of motors ( Larminie & A ; John, 2003 ) : Motors are fundamentally categorized into DC motors and AC motors.3.51 DC motors:Extensively used boulder clay 1990 ‘s Has 2 sets of windings- stator and rotor The torsion is maintained by commutator coppices Weaving in the rotor is called armature and twist in stator is called field twistAdvantages:Ease of control due to one-dimensionality Capability for independent torsion and flux control Established fabrication engineeringDisadvantages:Brush wear that leads to high care Low upper limits velocity EMI due to commutator action Low power to burden ratio Low efficiency Larger size3.52 AC motors:Armature circuit is on stator which eliminates the demand for commutator and coppices Types: Synchronous – lasting magnet type, electromagnet type Asynchronous – squirrel coop, lesion rotor. 3.53 Permanent magnet type AC motors ( Hussain, 2003 ) : They use magnets to bring forth air-gap magnetic flux alternatively of field spirals. Types: Permanent magnet synchronal motors Sinusoidal brushless DC motor Trapezoidal or square moving ridge motor Advantages: Supply a loss-free excitement in a compact manner without complications of connexions to the external stationary electric circuits High power to burden ratio High torsion to inertia ratio Excellent field weakening features Disadvantages: Not economical Sensitive to temperature and lade fluctuations3.54 Switched reluctance motors:Doubly salient, singly aroused reluctance motor with independent stage twists on the stator. Generally stator and rotor are magnetic steel laminations with rotor holding no magnets or twists. Advantages: Simple and low cost machine building Wider changeless power part Bidirectional currents are non necessary, therefore lesser figure of power switches Most of the losingss appear in stator, which is easier to chill High torsion to inertia ratio Torque-speed features of the motor can be tailored as per demand Maximum allowable rotor temperature is high Disadvantages: Torque rippling and accoustic noise observed Particular convertor and higher terminal connexions required, therefore non economical. 3.55 Choice: Torsion to inertia ratio Power to burden ratio Field weakening Torque rippling Acoustic noise Peak torsion efficiency Monetary value and care cost I? motor definition standard DC motors 6 3 3 6 3 6 3 9 39 PM Synchronous motors 9 9 9 9 6 9 Hence it is better to integrate PM synchronal motor or Switched reluctance motor in the electric auto. After mentioning the above chart, its apparent that PM synchronal AC motors are more suited for moderate power demands. 3.6 Power electronics in electric auto ( Hussain, 2003 ) : Electric motor thrust converts stiff DC battery electromotive force to DC/ AC electromotive force with a RMS value and frequence that can be adjusted harmonizing to the control bid. Electric motor thrust: Its typically is a combination of, POWER ELECTRONIC CONVERTER + ASSOCIATED CONTROLLER Power electronic accountant: It is made up of solid province devices and grips flow of bulk power from the beginning to motor input terminuss. It functions as ON/OFF switch to change over fixed supply electromotive force into variable electromotive force and variable frequence supply. They constitute of high-power and rapid response semiconducting material devices. Drive accountant: It accepts bid and feedback signals, processes it and generates gate exchanging signals for the power devices of the convertor. It is made up of microprocessors and digital signal processors. Figure: Block diagram of motor thrust ( Hussain, 2003 ) Figure: DC-DC and DC-AC convertors ( Hussain, 2003 ) 3.61 Power electronic switches ( Hussain, 2003 ) : BJT: Bi-polar junction transistors have better power evaluations and first-class conduction, but their thrust circuit is complicated as they are current-driven. MOSFET: Metal oxide semiconducting material field consequence transistor has simpler drive circuits and higher shift frequence, but their upper limit available power evaluations are lesser than BJT. IGBT: Insulated gate bipolar transistor incorporates the advantaged of both BJT and MOSFET and are extensively used in modern twenty-four hours electric autos. SCR: Silicon controlled thyristor have higher power evaluations but requires a commuting circuit to exchange them Off. GTO: Gate turn-off SCR is a type of jury-rigged SCR that can be switched off through a gate signal but their current ingestion is typically 4 to 5 times the current required to exchange them on. MCT: MOS controlled thyristor combines the conductivity features of SCR and gating features of MOSFET. Diodes: They are two-terminal semiconducting material devices and are used in concurrence with other accountant devices. Their map is to barricade the contrary electromotive force flow and supply current way for inductive circuits. 3.7 A typical PM synchronal motor thrust construction: ( Hussain, 2003 )LIGHT WEIGHT STRUCTURES4.1 INTRODUCTION TO STEELSSheet steel has remained the chief stuff used for the building of the organic structure of a motor vehicle of all time since mass production began earlier this century. Steel is comparatively is inexpensive and can be economically formed to do parts with complicated forms and has a high grade of rigidness, higher clang impact opposition and high elastic modulus. In the recent yearss, aluminum metals have been extensively used for car constituents. The metal has aluminium as base metal with hints of Cr, Cu, Fe, Mg, manganese, Si, Ti and Zn added to it. The proportions are differed harmonizing to the demand of the terminal merchandise and these metals are about replacing the steels in car sector. The indispensable factors behind this development have been the demands to cut down fuel ingestion by cut downing the weight of auto and increased rider safety ( C.Dasarathy , 2010 ) .4.2 STEEL USED IN AUTOMOBILEA ­A ­A ­As sheet As forged subdivisions As wire merchandises Hot rolled sheet t=1.5-7.00mm for organic structure panels, closings, biw parts, sumps, fuel armored combat vehicles, fumes parts. Crank shafts, linking roads, axle parts, tie rods, valves. For tyre support, springs, etc For organic structure, under organic structure structural parts cold rolled -annealed -coated sheet=0.5-1.5mm4.3 ALUMINIUMAluminum is a metallic component, and its construction is similar to most other metals. It is ductile and malleable due to its polycrystalline construction. Aluminum is made of grains which interlock when the metal is cooled from molten. Each grain comprises of rows of atoms in ordered lattice agreement, giving each grain an isotropic construction. Although the different grains are slightly indiscriminately arranged with in grain boundaries organizing during the chilling procedure, the atoms within each crystal are usually aligned which makes the metal isotropic, like the single grains. ( Sam Davyson )4.4 ALLOYING ADDITIONS FOR AUTOMOBILESA little measure of other elements added to aluminium in order to modify its basic belongingss. They are chromium, Cu, Fe, Mg, manganese, Si, Ti and Zn. These elements can be grouped into those with high solid solubility and thos e with low solid solubility.4.5 PROPERTIES SPECIAL STEEL & A ; ALUMINIUM ALLOYSProperties Particular steel Aluminium metal Weight & A ; denseness Heavier in weight with denseness of 7.85gm/cu.cm Lighter in weight with denseness approx 1/3rdof that of steel. The denseness is about 2.72gm/cu.cm Elastic modulus & A ; flexing specific stiffness Elastic modulus of 210 Gpa longitudinal i.e. immature ‘s modulus which 3times more than that of aluminum. But flexing stiffness is more than aluminum which provide more advantage for utilizing in constructions like forepart clang tracks, b-pillars etc. Elastic modulus of 70 Gpa. It has got shock soaking up inclination so largely used in car bumpers. It is used as outer tegument surface in car it has greater specific bending stiffness for level merchandises. Thermal conduction Less thermic conductive than aluminum 3 times more thermic conductive than steel doing it a pick in heat exchange applications. Fatigue Fatigue public presentation of steel is more than twice that of aluminum. Steels such as DUAL PHASE 600 AND TRIP 600 have endurance bounds of 307 Mpa & A ; 336 Mpa severally. Structural aluminum class of 5XXX series does non make an endurance bound and go on degrading at higher rhythms. Aluminium grade 5052-0 ranges 124 Mpa at 500 million rhythms. Formability High formable scope than aluminum doing it suited for vehicles titling and overall fabrication hardiness. Formability is about 2/3rdof that of steel. Electrical conduction Nowhere near aluminium electrical music director in power transmittal. High electrical conduction for usage as lines, transformers, coach bars etc. Coefficient of reflection Lesser reflective than aluminum. Excellent reflector of radiant energy throughout full scope of wave lengths. Light reflecting capacity of over 80 % doing it suited for light fixtures. In roofing, it reflect high sum of Sun heat advancing cool inside ambiance in summer. Non-magnetism Steels in general are magnetic. Austenitic chromium steel steels are non magnetic with AISI 304LN, 316LN some steel classs possessing really low magnetic permeableness for usage in constructions near to sensitive electronic devices or medical equipment. It is extremely nonmagnetic and therefore happening extended usage for electrical shielding such as coach saloon, magnetic compass lodgings, computing machine phonograph record fabrication, parabolic aerial etc. High temperature opposition Steels like T-11, T-22, martens tic chromium steel and austenitic chromium steel steel like AISI 310 are extremely creep resistant with ability to defy distortion at high temperatures. Steels incorporating 8 % aluminum. Poor high temperature opposition Low temperature stamina Steels in general posses hapless low temperature stamina. Shows first-class stamina at low temperatures happening usage in infrigidation. Tensile strength Much higher than aluminum and its metals. Tensile strength of pure aluminum is really much lower but, the belongings can be improved by add-ons of Mn, Si, Cu & A ; Mg and through annealing aluminum metal has a tensile strength of 295 Mpa. Output strength Very much higher than aluminium metal The mechanical belongingss are improved by add-ons of Mn, Si, Cu, & A ; Mg and through annealing.

Show first-class machinability Hardness Harder than aluminum denting inclination less than aluminum Lower hardness than steel. Muffling features Ability to rarefy air bone noise due to its immense mass over aluminum. Inability to rarefy air borne noise compared to steel Strain rate sensitiveness High strain rate sensitive exposing positive strain rate public presentation. Not strain rate medium and has hapless clang worthiness. Corrosion & A ; weather opposition Austenitic chromium steel steel like AISI 304 & A ; 316 shows first-class corrosion opposition. Shows good gal vanic, cavity and inter-granular corrosion opposition Good corrosion opposition and the rate of corrosion is 1/25thof high opposition steels. It is first-class conditions resistant. Non toxicity Austenitic chromium steel steels 300 series are known for their non -toxic nature. Tin home base steels are used for continuing nutrient, comestible oils etc. Highly non-toxic. Aluminium foil wrapping 500 foil of 0.007mm thickness is wholly impermeable. Aesthetic entreaty Excellent for austenitic chromium steel steels with low care costs. Attractive visual aspect with low care costs. Discoveries use in facing, hardware etc. Table 4.4.1 ( B.V.R Raja )4.6 CHASSISThere is batch of accomplishment and engineering behind the development and usage of honeycomb human body. The typical portion of aluminum tegument in honeycomb panel is good in certain countries. Honeycomb human body can take great important tonss on border. But this ca n't take much burden in 90 grades to that great extent. The design panel is immune to all conditions conditions although they are non designed to expose to atmosphere. The bonding between the honeycomb and the aluminum tegument is really strong to H2O resistant but the bonding is non H2O cogent evidence. So when planing the human body we must take effectual stairss to forestall to maintain route H2O and salts out off the panels and articulations to avoid corrosion and harm to human body. More proficient accomplishment is required while repairing the panels. To the specific demands, you needed to attach the panels without impacting their physical belongings. We ca n't concentrate o r sleep together the panels together for perfect bonding. ( Cliffbeer, 2007 )4.7 RACK AND PINION SYSTEMIn rack and pinion type, the cogwheel on the maneuvering column ‘s terminal is similar to the pinion cogwheel in the differential cut on an angle, and meshed with a steel saloon ( the rack ) toothed on one side. The rack is mounted parallel to the forepart axle and as the maneuvering wheel bends, it operates straight on the tie rods without the usage of a pitman arm, loafer or intermediate ( or relay ) rod. Adding a power aid to this type of guidance is rather simple. The power Piston is really portion of the rack, and the rack lodging Acts of the Apostless as the cylinder. The control valve is located in the pinion lodging. Rotation of the guidance shaft and pinion turns the valve to direct hydraulic force per unit area to either terminal of the rack Piston.4.8 MACPHERSON STRUT FRONT SUSPENSIONThe most widely used forepart suspension system in autos of European beginning.The system comprises of a strut-type spring and daze absorber jazz band, which pivots on a ball articulation on the individual, lower arm The prance itself is the supporting member in this assembly, with the spring and daze absorber simply executing their responsibility as oppose to really keeping the auto up.4.9 MULTI-LINK REAR SUSPENSIONThis is the latest embodiment of the dual wishing bone system. The basic rule of it is the same, but alternatively of solid upper and lower wishing bones, each ‘arm ‘ of the wishing bone is a separate point. These are joined at the top and underside of the spindle therefore organizing the wishing bone form. The super-weird thing about this is that as the spindle turns for maneuvering, it alters the geometry of the suspension by torquing all four suspension weaponries. ( Chris Longhurst, 1994-2004 )4.10 AERODYNAMICSAeromechanicss encompass all the air flows that base on balls over, around, and through a vehicle they can be subdivided in those impacting performance/ fuel ingestion, comfort, chilling, vehicle kineticss, directional stableness and perceptibility safety.

In order to retrieve the energy, two types of system are applied. Solar Energy Panels Regenerative Braking System 5.1 Solar Energy Panels ( Darrell D. Ebbing, 2007 ) ( SPI, 2005-2010 ) ( Inventables, 2007 ) Solar energy is the largely available energy in the universe. Taking this into cognition, we introduce solar panels which convert solar energy into electric energy and are stored in the battery. There are two sort of solar panels used: – Transparent and flexible solar panels Plate type solar panels The Semi transparent and flexible solar panels will be placed on each Windowss of the vehicle. So that the both the side of solar panel can be utilised consequently and with the aid of the green house consequence, it helps in bear downing the battery from both the sides. The Plate type solar panels will be placed on the roof of the vehicle and for the use of maximal solar energy All the charges obtained from the solar panel will be stored in the battery utilizing a control unit. Power available 20W ( Plate type solar panels ) 10-14W ( Semi transparent and flexible solar panels ) Charging Time 6-8 hour ( 45 % – 60 % ) Nominal Voltage 12v ( approx. ) Maximal Power Voltage 17.5v ( approx. ) Maximal Power Current 1.1A ( approx. ) Open Circuit Voltage 21.0v ( approx. ) Short Circuit Current 1.3A ( approx. ) Cost 400 ( approx. ) Table 5.1.1 Specification of the solar panels used. ( navitron, 2004 ) 5.2 Regenerative Braking System ( Boxwell, 2010 ) ( Brain, 1998 ) Regenerative braking system is an alternate manner used to bring forth electrical energy from kinetic energy produced through braking. This energy is produced by the rearward rotary motion of the motor used in the vehicle. As vehicle go down the hill or into halting point by braking, the electronic circuit or accountant would do the motor rotate backward with the aid of the tyres and in this instance, the motor which rotates the wheel would move as a generator to bring forth the electricity. This charge produced will be stored in the battery utilizing a control unit. By this system, the energy lost would be recovered and stored, therefore increasing the efficiency of the vehicle ( Automotive constituents and parts, 2008 ) 6.0 Parasitic Losses ( Vehicle Technologies Program, 2009 ) Parasitic loss is chiefly known as the loss of the energy in the system. For electric autos, the parasitic loss is chiefly due to the air current opposition and retarding force, braking and turn overing opposition. It even includes the clash and wears in the vehicle, thermal ( heat ) loads, operation of subsidiary tonss ( air conditioning, warmers, infrigidation, etc. ) . ( Inventables, 2007 ) This parasitic loss can vastly impact the efficiency of the vehicle.Electrical ConsumerPower end productAverage power end productElectric motor Radio 80kW 20W 75kW 20W Side marker lamps Low beam ( lordotic beam ) License – home base lamp, tail lamps Indicator lamp, instruments Heated rear window Interior warming, fan Electrical radiator ventilator 8W 110W 30W 22W 200W 120W 120W 7W 90W 25W 20W 60W 50W 30W Windshield wiper Stop lamps Turn signal lamps Fog lamps Rear fog warning lamp 50W 42W 42W 110W 21W 10W 11W 5W 20W 2W Entire Installed electrical burden demands Average electrical burden demands 80,895W 75,350WTable 6.1 demoing the ingestion of constituents of an Electric vehicle( Automotive Handbook, 2007 ) Therefore the parasitic losingss occurred in the electrical constituents = 80,895-75,350=5,545W Hence there is an approximative parasitic loss of 5kW and more in this system.7.0 HVAC ( Heating, Ventilating and Air Conditioning )HVAC ( Heating, Ventilating and Air Conditioning ) is a engineering that deals with the indoor or automotive environment control with the rules of Thermodynamics, Fluid Mechanics and Heat transportation. Heating, Ventilating and Air Conditioning are closely interrelated in order to supply a thermic comfort in the indoors. Since it is used to command the quality of air it is besides referred to as Climate control. HVAC is non merely of import in the design of medium to big industrial and office edifices and in marine environments but besides in cars such as autos and trucks where safe andA healthyA conditions are regulated with temperature and humidness. Since, HVAC systems account for so much electric energy usage, the efficiency of the system has to be improved through proper design, installing and scheduled care. HAVAC Systems perform conditioning the air in the undermentioned ways Removing and adding heat. Adding and taking wet. Volume of air flow. Speed of air flow. Removing Impurities in air. Fig 7.1 Ventilation System. ( National Research Council Canada ) Aim Supplying an acceptable degree of tenancy comfort Care of good air quality Minimum energy demands Minimal cost Proper air flow, heating and chilling.7.1 HVAC TYPESThe move to battery powered electric autos poses several challenges when it comes to climate control inside the vehicle. The enormously inefficient internal burning engine ‘s coolant system can easy be tapped for cabin warming are now gone while powering a 3 – 5 kilowatts air conditioning compressor in an EV consumes merely 200 wh/mile atA main road velocities. There are different types of HVACs used in Electric Vehicles.THERMOELECTRIC DEVICES FOR AIR CONDITIONINGThe thermoelectric HVAC will be optimised to supply the occupant comfort while cut downing fuel ingestion and nursery gas emanations. To maximise energy efficiency, the thermoelectric HVAC system will utilize a distributed warming or chilling design that targets single residents and reduces temperature conditioning to unoccupied rider seating. Tetrafluoroethane ( R-134a ) refrigerant gas is the most common working fluid in vehicular air conditioners since 1995. R-134a has 1300 times greater nursery gas impact than CO2. Car air conditioners leak 10 to 70 g/year. Thermoelectric HVAC systems significantly cut down adult male ‘s part to greenhouse gases while bettering fuel economic system. 7-8 billion gallons/year of fuel usage for automotive A/C. Approximately 6 % of our national responsibility fuel usage ( ELECTRIC VEHICLE NEWS, 2009 ) .Climate CONTROLLED SEATS ( CCS )This HVAC engineering heats and cools environing constructions such as the star, Windowss, flooring, and place dorsums. These systems consume between 3.5-5 KW. To cut down this burden, heating or chilling can be plumbed straight into the seats. These seats are called Climate Controlled Seats ( CCS ) . Since the place has direct contact with the resident it has much higher thermic conduction compared to air which is a hapless music director. With direct contact chilling or heating burden per individual could be reduced to less than 700 Watts compared to 5,000 W to heat/cool the full cabin ( Fairbanks, THERMOELECTRIC DEVELOPMENTS FOR VEHICULAR APPLICATION, 2006 ) . Fig. 7.1.1 Climate Control Seats. ( Fairbanks, 2006 ) Fig 7.1.2 HVAC System in Electric Car. ( Electric VEHICLE NEWS, 2009 ) Advantage This program presents scenarios for increased usage of alternate fuels and vehicle engineering efficiency betterments in order to cut down power ingestion and nursery gas emanations. This system will show a lower limit of 33 % betterment in the energy consumed by a vehicle air conditioning system. ZT ( figure of virtue ) ~ 1 ; COP ~ 0.9-1.0 ; Distributed HVAC System ; P ~ 2 kilowatt ; Power Off Alternator Decreases ~ 0.8 mpg/vehicle ( 0.8/27.5 ~ 0.029 ) low Alternator Efficiency ZT ~ 2 ; COP ~ 2 ; Distributed HVAC System ; P ~ 1 KW ; Power Off Alternator Additions ~ 1.1 mpg/vehicle ( 1.1/27.5 ~ 0.04 ) Either ZT Case ; Power From Thermoelectric Generator Converting Engine Exhaust Heat to Electricity Additions ~ 3 mpg/vehicle ( 3/27.5 ~ 0.11 ) ( Fairbanks, THERMOELECTRIC DEVELOPMENTS FOR VEHICULAR APPLICATION, 2006 )PELTIER EFFECT THERMOELECTRICPeltier faculties can be used to bring forth electricity, to supply air conditioning or they can be used to supply warming. In fact, Peltier faculties make it possible to construct various warming and chilling devices for applications that require an energy efficiency solution. Peltier faculties are thermoelectric ( TE ) devices that can be used to supply chilling or to bring forth electricity, depending on the application. The faculties work harmonizing to the Peltier/Seebeck consequence, which provides chilling by go throughing a current across two dissimilar stuffs, that ‘s on opposite sides of the device. The current flow causes one side of the device to go hot and the other to go really cold. A Peltier air conditioning solution can be built by configuring the Peltier faculties to accept a current, which will chill one side of the faculty and heat the other. In this constellation, Peltier faculties are frequently referred to as TEC or thermoelectric ice chests. The hot side of the Peltier faculty will necessitate a heat sink and a chilling fan to forestall overheating. The cool side of the Peltier faculty can so supply chilling by doing the Ac fan to blow air across them. The same faculties can besides supply warming by altering the way of the current flow. This will do the hot side to go cold and the cold side to go hot, which makes Peltier faculties an all unit of ammunition warming and air conditioning solution ( Fairbanks, CAR and Vehicle Technologies Energy Efficiency and Renewable Energy US Department of Energy Washington, D.C ) .7.2 AUXILIARY POWER UNITAn Auxiliary Power Unit ( APU ) is used in the motor and electric vehicles in-order to supply energy for the vehicl e other than get downing up of engines. It is used for runing the power Windowss and Cabin light even before get downing up of engine. The traditional APU is powered by fuel, which is less efficient and causes more pollution than the emerging battery powered APU ‘s. Fuel cell APU is a typical type which uses fuel cell as a beginning of energy but involves no burning and so is clean and efficient.AUXILIARY POWER UNIT IN ELECTRIC VEHICLESA battery electric vehicle has a comparatively little fuel cell subsidiary power unit ( APU ) to reload the battery battalion during driving. The attractive force of this constellation is the usage of a comparatively little battery battalion ( to let 65 – 110 kilometer of ZEV scope ) while increasing vehicle scope and functionality to be tantamount to conventional vehicles ( 400 – 650km ) . Another cardinal attractive force is that a bulk of kilometer could be expeditiously refueled from the grid leting low or zero CO2 power bring forthing engineering to be deployed in private transit without the tremendous cost and inefficiency of the H2 substructure ( Zizelman, 2000 ) . FUNCTIONS OF APU APU in a auto is responsible for and provides power to the Cooling system Heating system Generator/alternator system Air conditioning compressor SOLID OXIDE FUEL CELL APU The combination of Solid Oxide Fuel Cell ( SOFC ) APU and advanced Lithium Ion battery systems appears to do the fuel cell scope extender EV an attractive system in footings of efficiency, weight and cost. The add-on of the APU on the vehicle enhances the value of the vehicle to the electric grid by leting the vehicle to run as a back-up generator for the edifice next to which it is parked. Delphi has been making R & A ; D on fuel reforming and fuel cells since 1990. The SOFC plan began in 1999 with a customer-linked plan to develop a 3-5 kilowatt APU merchandise for luxury rider autos running on gasolene. The SOFC APU is a practical first measure for debut of fuel cells in transit. But its linkage to luxury maps ( like electric air conditioning ) alternatively of propulsion and its usage of conventional fuels, alternatively of direct H2, may do it look like a cautious first measure. However a assortment of future integrating schemes for combined rhythm SOFC/ICE, SOFC intercrossed vehicles and the SOFC/Li-Ion scope extender EV offer a broad spectrum of future â€Å" green † applications. In add-on, SOFC is capable of firing H2 or other renewable fuels really expeditiously. The SOFC system will inherently hold highly low emanations. No NOx will be formed in the reforming procedure and the post-combustor will run at temperatures where no NOx and hydrocarbons are fo rmed. But, the SOFC was assumed to accomplish a 40 % efficiency degree for the coevals of electricity ( ( Delphi ) , 2002 ) .8.0 Final Selection & A ; Remarks8.1 DFMEA:Design Failure Mode Effect Analysis is a systematic analysis of possible failure manners aimed at forestalling those failures.

Is illegal immigration beneficial to the U.S. economy Term Paper

Is illegal immigration beneficial to the U.S. economy - Term Paper Example Illegal immigration, also known to as unauthorized or undocumented immigration refers to the passage and settlement of immigrants in a manner that contravenes the immigration rules and regulations of the destined country. Barry Chiswick, PhD, Distinguished Professor and Head of the Department of Economics at the University of Illinois at Chicago  defined illegal immigration as follows; "By definition, illegal immigration arises from a divergence between whom the United States will accept as an immigrant and the desire of some foreign nationals to live and work in this country† (Procon 2007). Broadly speaking illegal immigration may take the form of undocumented/unauthorized entry, admission gained through fraudulent documents, extending the stay after the expiry of the temporary visas or crossing the border illegally. An estimated 11.9 million unauthorized immigrants live in the United States. In the last decade, on average, 5, 00, 000 new illegal immigrants made their way into the United States every year. The tally of total immigrant population in the United States touched 40 million in 2010, the highest in the history of the country. Approximately 66 percent of the unauthorized immigrants come into the United States by crossing the US-Mexico border; making Mexico the top illegal-immigrant-sending country. The rest of the one-third illegal immigrants reportedly continue to stay on in the country after the expiry of their temporary visas (Hanson 2009). At one point of time, the phenomenon of illegal immigration served the national interests of United States Pretty well. The illegal immigrants are willing to take up jobs in labor-scarce regions and also have no problems in accepting jobs that native workers and legal migrants shun. The illegal immigrants hold anywhere between 12 to 15 million jobs or 8 percent of the jobs in the United States (Hanson 2009). For varied reasons the existence of

SB 1070 Essay Example | Topics and Well Written Essays - 1250 words

SB 1070 - Essay Example The Illinois’s legislative bill 123 together with the Arizona’s â€Å"Support our law enforcement and safe Neighborhood Act† is the strictest and wider anti-illegal immigration legislative act in the recent times. This bill intends to include more provisions to the federal laws of the United States of America. First, it would be a crime for individual aliens to be in the state of Illinois without the registration documents. It would also restrict the other state, local agencies and officials from the restricting enforcement of the federal immigration laws in the state of Illinois (Ferris, 289). It also provides for the crackdown for the individuals who are harboring, transporting or hiring aliens in the state illegally. This has been described as the strictest immigration law united states. The intent of these additional provisions was to reduce the number of illegal aliens who are estimated to approximately 460, 000 in Arizona only and even more in the state of Illinois and others states in the U.S. ... The act provides for the state law enforcements agencies to question, arrest or detain individuals who are reasonably suspected to be in the country illegally. In this context the act gives the state law enforcement agencies to enforce the law and ensure that the immigrants abide by the state laws. According to Warner (68), this is unconstitutional because the responsibility of enforcing the immigration laws is a federal responsibility and not a state responsibility. If there is reasonable suspicion that they might be in the country illegally, it is the responsibility of the federal governments to enforce the laws. The Illinois’s bill 123 can be described as a bill that affects foreign matters and hence its effect when passed into law would affect the foreign policy of not only the Illinois but also the United States o America. The unconstitutional nature of this act is that the state does not have powers to pass laws that affect the foreign policy and relations. According to Warner (69), just like the states have no authority of passing their own foreign policies or enter into treaties with the other nations of the world, they do not have immigration policies and laws. The argument here is that the immigration laws is an attribute of the foreign affairs and hence the state law enforcing agencies and officials do not have any little power to pass such laws. The signing of the law into affect would therefore mean that the state of Illinois has a different foreign policy compared to the United States of America foreign policies in general and hence it is therefore unconstitutional. The role of a state in enforcing federal immigration laws is provided for in the federal laws of the united state of America. However

Assess the effect of the French Revolution on the nature of the state Essay

Assess the effect of the French Revolution on the nature of the state and on relations between states - Essay Example The significance of the French Revolution became one that was used to redefine the national relationships that were a part of France. Redefining the French Revolution The French Revolution was caused by a series of events in the political realm that led to revolts and the desire for change. Each of these caused the general public to react with the belief that change needed to occur within France and that the national politics were only offering injustice to those that were within the region. There were several turning points described throughout the revolution, including the Fall of Bastille, massacre at Champ de Mars, fall of the monarchy and the rise of Napoleon. Each of these led to different proclamations and a sense of change that was associated with the revolution. These different components led to a sense of defining one’s position in France as well as how this was associated with those that were loyal to the government as opposed to individuals who held a position that led to revolt (Hunt, 53: 2004). The outcomes and divisions created from the French Revolution began with the precursors that were associated with this time in history. The main component was the political restructuring that was used so collective action could be taken during the revolution. Political structures were able to provide more dynamic opportunities during the revolution and defined the voices that were associated with the social movement. The most important concept with the structures were based on the policies that were divided, specifically which led to a change in relationships because of the division. Policy specific concepts were combined with state variations used during the revolution. This also formed with the policies causing the divisions among groups that were involved in the revolution. As the groups formed in favor or against the policies, it changed the nature of the state and created a different relationship with the overall political dynamics of France. Th is led to large scale structures that eventually changed the nature of France from the nature of the state and groups involved (Mcadam, McCarthy, Zald, 42: 1996). Defining the Nature of States There were several policies that became the central component of defining the nature of states. As groups began to look through policies and form a change in the states from societal status, were also noted areas of corruption that were pointed out. The main component was the division between those loyal to the French government and those opposed to the actions taken. The policies in place were defined by the monarchs and statesmen of the 17th century who had established a specific set of legalities for actions taken. This was based on the fiscal system and economic mediums that were used. The divisions over how the economics should work were divided by the groups of clergy, nobles and commons, all which debated as estates who were interested in the fiscal policies and justice system of France . These three groups then led to creating independent from the current fiscal system through the component of justice. The group divisions led to the creation of states and a different nature of how the economic concepts should work within France (Burke, 11:2000). The driving force behind the division not only led to a change with fiscal policy. The French Revolution also led to divisions by groups who were outside of the three main estates.

See attachment as well as attachment Coursework

See attachment as well as attachment - Coursework Example (Schaefer 2010) Mexican Americans have been living in American a since very long time and have adjusted and adapted themselves to the requirements of the culture and societal norms of the country. According to survey in 2006 it came into light that 14 percent of the registered immigrants in the United States belonged to Mexico. Mexican Americans are very diverse in their spoken language. Around 26 percent of Mexican Americans can converse in both English and Spanish. Due to the language differences with the mainstream, the Mexican Americans have been overlooked and disregarded in the political field similar to other Hispanic groups that have been ignored. However they have established voting rights and they can vote without any quandary. Moreover, as they form a large percentage of the population, their voting power is very essential for the leaders who approach them for their votes. As a result of their importance for forming an important voting force they have political strength. However, they st ill counter injustice and prejudices in terms of reforms for immigrants, education, etc. They practice Catholic religion. Their economic conditions however differ as compared to those of the born Americans. When compared to the Native Americans unemployment and poverty is higher among the immigrant population. (Schaefer 2010; Keedle 2010) Another prominent group of Hispanics in America are the Puerto Ricans. These Americans have been a vital part of American History and they have been more diverted towards English language. This group has still not been successful in accepting the American identity completely and is known to be undergoing the phenomenon of Neo Colonialism. Their economic status is not as healthy as the whites because they also fall victim to high unemployment rates. They do not have availability of stable jobs in

Why Women Should Not be Allowed in Active Combat Duty Essay

Why Women Should Not be Allowed in Active Combat Duty - Essay Example They are admirable in the way they acquit themselves in times of conflict and split second decision making and maybe, just maybe -- we might even have a female president some day. Women still have lofty ambitions when it comes to more things that they hope to do in terms of male equality and, along with the presidency, fighting alongside men in active combat is still one glass ceiling they cannot break. Although there already exists cracks in that particular ceiling, I do not believe that women should ever be allowed to see active combat for a number of valid reasons. There are two main reasons that women should not be allowed in combat according to Robert Bork (qtd. in Sowin). Those reasons are: 1. Putting women in combat is crucial to women’s self-esteem and to men’s respect for women. (That has never been true in the past and it is impossible to see why it should be true now.) 2. Combat roles are important to military advancement. The above arguments are all based up on the way that women are traditionally viewed in our society. Women's rights activists protest the idealization of the female role in society because it makes them seem like fragile, emotionally weak people who do not have any desire or capability to defend themselves or others. By joining the military and joining active combat, women feel that they are an equally strong sex and are capable of fighting the good fight also. This is one case wherein the intentions may be sound, but the execution will always be weak. The reality of women in the military is that they are given preference and leeway in most streneous and taxing activities because women do not have the same stamina as men. In fact, women who train in West Point and other military institutions are not made to compete against other men or by male standards, they are only measured in terms of capabilty against other women. This can prove to be detrimental on the battlefield where they fight alongside men who are faster and stronger but are then held back in order to allow the women to catch up. (Sowin Why Women Should Not Be Allowed in Combat). Gender norming and lowering the training standards in order to allow women to pass is a disservice to our world class soldiers who are expected to lead on the battlefield. Women are still thought of all over the world, most specially in the Muslim territories as being weak and dependent on the male species. Majority of the modern women have managed to change that idea by proving that they can be emotionally and physically strong in various ways. I take my hats off to those women. However, fighting in an active battlefront requires much more than just marathon training and endurance tests. There are those who take on the point of view that : Women are not suited by temperament or by physical characteristics for the highly aggressive, ultra-violent pursuit of victory in battle. Much of an army’s success depends upon intimidation of the enemy. A force compo sed of women is far less intimidating than one consisting of macho men. Intimidation of the enemy saves lives in wartime. (Women Should Not Be Allowed in Military Combat). Consider if you will, that the enemies of our nation field burly, scary, and brainwashed men into battle. They live to intimidate the weak. The simple glare of of their eyes, flare of the nostrils, or clearing of the throat is designed to instill fear into any enemy be he male or female. Fighting a war does not allow for segregation of the sexes in order to effectively fight the battle. It is man vs. woman in most cases and, no matter what Hollywood says about G.I. Jane, a woman can easily be taken down by a well trained and strength enhanced enemy. This will then pose a problem for the team who will

Johnson & Johnson as a Model for Corporate Social Responsibility Research Paper

Johnson & Johnson as a Model for Corporate Social Responsibility - Research Paper Example Three responsibility-related dimensions are taken into account to calculate the combined effect on reputation of social programs, management practices, and employee relations. These include corporate citizenship, governance and workplace practices. An organization’s reputation is closely linked to the public perception of its Corporate Responsibility. Public perception includes dimensions such as trust, admiration and esteem. J&J makes certain claims in its annual reports and other official publications. However, an examination of their activities disproves the hypothesis that Johnson & Johnson is a model for Corporate Social Responsibility. 2. Company’s CREDO The company – J&J follows a definite CSR strategy outlined in OUR CREDO which was initiated 60 years ago by the founder. The Credo describes of the organization’s responsibility towards its customers, employers, communities and shareholders (Fact Book, 2007). Their first responsibility is to the doctors, nurses and patients, and all others who use their products and services. This includes product quality, product prices, prompt service, and a fair opportunity to the suppliers and distributors to make profits. Toward the employees their responsibility lies in providing job security, respecting individual dignity, and also helping employees fulfill their responsibilities towards their families (CSR Globe, n.d.). ... Their first responsibility is to the doctors, nurses and patients, and all others who use their products and services. This includes product quality, product prices, prompt service, and a fair opportunity to the suppliers and distributors to make profits. Toward the employees their responsibility lies in providing job security, respecting individual dignity, and also helping employees fulfill their responsibilities towards their families (CSR Globe, n.d.). They claim to be equal opportunity employers and hence provide development and advancement for all those qualified. Towards the communities they feel responsible in supporting charities and encouraging civic improvements including better health and education. Protection of environment and natural resources is a part of their responsibility towards the society and communities. They have a worldwide Tobacco-Free Work Place policy which has helped improve the health and work environment for the employees. For the employees they have o ther programs such as the Employee Assistance program and the Occupational Health Program which influences the employees’ ability to work safely and effectively keeping in mind the laws and regulations. The company asserts that if it has taken care of the first three - customers, employers, communities - the responsibility to the stakeholders is automatically assured. The Credo is the central document that ties many operating companies together. The positive effect of all its CSR strategy is that the company practices decentralization across J&J group of companies. Their focus areas are health, education, environment, art & culture, and disaster relief. They align their corporate

Communities of practice, their benefits and management challenges Essay

Communities of practice, their benefits and management challenges - Essay Example This paper will look into Communities of Practice, their benefits and a number of management challenges that they pose in a knowledge-based organisation. A community of practice has numerous benefits to an organisation. Organisations the world over have been utilising Communities of Practice for the last 2 decades in order to have sound knowledge-management systems. It is however important to note that CoPs have existed for centuries within management circles but their full formal attention in a modern organisational setup only emerged in the early 1990s. A CoP is comprised of a group of people willing to share their knowledge and expertise for a considerable amount of time. Organisations have used them to develop their human resources and encourage innovation and new approaches to problem solving. The intensifying of globalisation trends in the 1990s triggered heightened global competition. In order to survive firms are supposed to be creative and innovating which has driven them to appreciate the role that knowledge plays in organisational development. CoPs assist in diffusing knowledge and leverage a firm’s intellectual advantages. Knowledge-based organisations therefore require CoPs in developing their knowledge strategies. As such CoPs also have their limitations in respect to management of a firm. This paper will look into Communities of Practice, their benefits and a number of management challenges that they pose in a knowledge-based organisation. A community of practice has numerous benefits to an organisation. Formerly, many firms used information systems in knowledge management but the results were disappointing. CoP offers relatively new approaches where people interact and learn together. Due to the benefits that this approaches have most firms have adopted CoPs (Wenger and Snyder 2000). Some of the key benefits are as follows; Help with challenges It is clear that all firms experience challenges in their day-to-day running. However, these ch allenges need to be dealt with and a community of practice should be established to do just that. CoP solves problems by pooling of expertise, knowledge and skills from a number of employees. It is important to note that their winding down and eventual shutting down happens when problems they were dealing with are solved and consequently their purpose is fulfilled. Access expertise Organisations that treasure CoP are predominantly knowledge-based meaning that they require a great deal of expertise to carry out their tasks. In order to have a successful CoP its membership should be comprised of knowledgeable and experienced people. In case a firm is short of such workforce it is forced to source for them. In doing this a firm attains a pool of experts within its workforce which works to improve on its performance and profitability. Enhancement of team spirit Members in a community of practice need to work together to achieve set goals. They are not necessarily people who share the sa me ideals or beliefs but they are required to have similar interests in order to ensure a solid group (Llewellyn and Hindmarsh 2010). This facilitates teamwork in decision making and strategy formulation. Saving on cost an time of searching for information A CoP is established in order to deal with problems or to develop solutions. A small team is assembled which analyses the way forward. The smaller the team, the less the time they take in coming up with a solution. A small team is also easily managed and it is relatively cheap to maintain. This saves a great deal of time that inter-departmental meetings would have taken for consultations. It also offers time for the rest of the employee to continue with their normal duties while just a handful of them are picked to deal with pending issues (Wenger and Snyder 2000). The opportunity cost would be too high in taking many workers’ time in decision making. Improvement in quality of decisions A CoP is comprised of carefully selec ted people who bring to the table high-level skills and expertise. This assures the firm that the discussions made are meaningful and that decisions arrived at have high likeliness of being the best for the particular situation. Firms that have many CoPs tend to have better operational strategies which

Franklin Roosevelt Essay Example | Topics and Well Written Essays - 750 words

Franklin Roosevelt - Essay Example He also had a natural charisma that helped him to connect to with all sections of American population. He was a natural orator whose powerful voice stayed the listener’s heart. He also had a sense of patrician responsibility towards the other people. FDR had a very strong character as well as requisite political skills to get his programs enacted and communicate his visions of America. FDR was a strong believer in democratic views that is  the center-left and  social-liberal platform and supported  social  justice and mixed economy.  To elevate the situation in 1930s, he offered various programs that were designed for promotion of economic and social equality of the people all over the country. These programs were specially designed for promotion of consumer protection, various social programs, environmental protection, universal health care, and equal opportunity for all. In 1910, when he entered politics and ran for state Senate from Dutchness County, the local Democratic  Party supported his candidature as the â€Å"paper candidate†. The main reason behind this was that it was  a Republican  seat so the party did not expect a  democratic  win.  However, with his typical strong character and charisma, he ran a tight campaign and won the election.  He used these qualities in his life  time and again  when he was facing adverse times in  his personal  and professional life  (Polenberg, 2000).  After this victory, he went from strength to strength in his political life and used creativity to attain his objective. On  the domestic  front, when he took power for the first time as the President, the country’s economy was in completely ruined due to deficit issues (Polenberg, 2000).  . As soon as he took the office, he enacted many  laws,  which were expressly designed to lift the country out of 1930s depression. Also, he as completely committed to New Deal concept and backed it completely. On  the foreign  front, the world

Full Day Kindergarten Essay Example for Free

Full Day Kindergarten Essay Full day kindergarten should be mandatory and of no extra cost for all of the elementary schools. This will boost the children’s academic achievement. The children that are exposed to full day kindergarten will learn more in literacy and mathematics than those in half-day kindergarten. The students that are in a full day program get to spend more time on their math, writing, and reading activities. The full day students also get the advantage of being able to participate in gym, art, and music classes. The half-day students do not get to experience gym, art, or music class. I have seen results first hand because I chose to put my son in a full day kindergarten versus the half-day. I chose to bring my son to a school that is located in Fridley so that he could receive the benefits of the full day kindergarten. The half-day program that Blaine offers has a very undesirable schedule for parents who work. The half-day schedule for Blaine elementary school is full days Mondays, Wednesdays, and every other Friday. I think that the earlier the educational intervention begins the higher the impact and the more likely the effects will be retained. Other than the health of a child, I think that nothing should be more important than their education. Giving children the opportunity to be in a full day kindergarten program gives them opportunities that the half-day students do not receive. One of the opportunities is being able to spend more time on reading, writing, and math. The teachers also have more time to sit one on one with each student one or in small groups and work on these skills. They also have a different theme for each month that they focus on. Some examples of the themes are the solar system, U. S. residents, maps, and the celebrations around the world. Children also absorb things more easily when they are younger. Being a mother of a full day kindergarten student, I see the results of the extra reading, writing, and math that the teacher does with him. My son is one of the youngest in his class and he is reading at a first grade level. As for his writing, he attempt to write big words using phonics. For example, I came home one day a few months ago and he had written on his dry erase board â€Å"I see a red ladebug†. He also brought home a worksheet that he had written about his favorite fruits. On this worksheet, he had written â€Å"watrmlon†. As far as his math goes, he is always measuring things in the house with a kid’s yard ruler. The themes that they work on each month give the students the ability to know what is going on in the world around them. My son came home from school one day and told me that there was a planet that was not considered a planet anymore. I did not know this and I was in complete awe. According to Debra Ackerman, â€Å"Children in full day kindergarten programs score higher on their achievement test than those in half-day programs. Full-day kindergarten advocates suggest that a longer school day provides educational support that ensures a productive beginning school experience and increases the chances of future school success. In both full-day and half-day programs, kindergartners spend most of their class time working on reading, language arts, and math activities, but the total number of minutes teachers devote to specific subjects differs. For example, 80 percent of full day but only about 50 percent of half-day programs devote more than 30 minutes each day to mathematics instruction. Sixty-eight percent of full day but only 37 percent of half-day classrooms dedicate at least 60 minutes to reading instruction each day. Perhaps most striking, 79 percent of full-day teachers read aloud to their students every day, compared to 62 percent of half-day teachers. Reading aloud is a critical activity in helping to develop children’s reading skills. Additional research shows children’s literacy learning is enhanced in full-day programs, as the full-day schedule provides a more intensive, ongoing, enriched language and literacy experience for the young child. (Ackerman) Children in full day kindergarten programs score higher on their achievement test than those in half-day programs. I asked my son’s kindergarten teacher, Ms. Janssen, what the average for reading was for her class. Ms. Janssen stated that the majority of her students are already in the first grade reading level as of the end of the second trimester. As said by the Indiana Association of Public School Super Intendants, â€Å"Full day kindergarten programs are associated with greater reading achievement gains during the kindergarten year than half day programs†. Plucker, 6) The students are graded on their writing and math abilities as well. According to the Kalamazoo Public Schools reports, â€Å"The group of kindergartners advanced in 2010 to first grade at Kalamazoo Public School, where 60 percent tested at or above the 50th percentile in reading on the Iowa Test of Basic Skills last April. That’s a 7-point increase compared to Kalamazoo Public School first-graders tested in April 2009, Rice said. On the Iowa Test Basic Skills math test, 52 percent of first-graders tested a t or above the 50th percentile last spring, a 12-point jump over spring 2009. The Iowa Test of Basic Skills are administered in schools nationwide and is a norm-referenced test, which means scores are based on how students perform compared to other test-takers. The Kalamazoo Public School results show that 60 percent of Kalamazoo students are in the top half of first-graders nationwide in reading and 52 percent are in the top half in math. † (Mack) Children who are in full day kindergarten have better social and behavioral effects than those who are in half-day kindergarten. When children are in school for the full day they have more time to get to know the other students. They get more time to interact together socially and they are learning while they are interacting. The students also get to go to specialists and they go with their classmates. Some of the specialists that Hayes Elementary offers are music, art, Spanish, and gym. Going to the specialist is something that the full day kindergarteners get to do and the half-day kindergarteners do not get to do. These students also get to spend more time with the teacher. This means that they will be less hesitant to approach their teacher. According to Clark, â€Å"Some researchers have examined social and behavioral effects. According to researchers, a clear relationship emerged between the kindergarten schedule and childrens behavior. Teachers rated children in all-day kindergarten programs higher on 9 of the 14 dimensions; there were no significant differences on the other 5 dimensions. Other researchers who have studied social and behavioral outcomes found that children in all-day kindergarten programs were engaged in more child-to-child interactions and they made significantly greater progress in learning social skills†. Clark) In the kindergarten classrooms of Hayes Elementary, the students get into groups called centers. During this center time, the teacher takes a group of five students to a table to do independent reading and the rest of the students go to a center. The centers are groups of three or four students and the students get to interact socially while doing something educational. Some examples of the centers are writing center, listening center, leapster center, and art center. The writing center is where the students can write freely. The listening center is where the students put on headphones, listen to directions, and write down what they hear. The leapster center is where the students get to play a handheld learning game that integrates math, reading, and spelling in the games. Finally, the art center is where the students get to draw and color what they want. When the time is up the students clean up as groups. A full day of learning offers many social and emotional benefits to kindergarteners. As stated by NEA, â€Å"They have more time to focus and reflect on activities, and they have more time to transition between activities. When children are taught by qualified teachers, using age-appropriate curricula in small classes they can take full advantage of the additional learning time—social, emotional, and intellectual— that a full day allows. Further, research finds that children adjust well to the full-day format. † (NEA) The full day kindergarten teachers plan and use the extra time in class well. The time in class is spent differently in both the full day kindergarten and the half-day kindergarten. According to the research that the Indiana Association of Public School Superintendents, â€Å"The research provides evidence that time in full day kindergarten programs is different both quantitatively and qualitatively from how time is used in half day programs† (Plucker, ii). Full day kindergarten offers benefits to teachers. Teachers prefer the full day program to the half-day program. If there is a child that is struggling with something, the teacher has the ability to find time to help that student. There is also more time to finish activities. According to Ms. Janssen, â€Å"With the full day program I am able to get through four reading groups versus two reading groups in one day. With the full day program we are able to go more in depth on our unit that we focus on in class. † (Janssen) According to the NEA, â€Å"Switching to full-day kindergarten gave teachers more time to plan the curriculum, incorporate a greater number of thematic units into the school year, and offer more in-depth coverage of each unit. (NEA) In the half-day programs there is less time for multiple activities. According to Dr. Martinez, â€Å"Many kindergarten teachers favor full day kindergarten because they find it difficult to balance cognitive activities and affective social activities in the short kindergarten day. † (Martinez, 2) Teachers also prefer full day kindergarten because there is more instructional time than that of a half-day kindergarten program. As stated by the Indiana Association of Public School Superintendents, â€Å" Across all of the schools in the Indiana sample, the proportion of instructional time is similar across program types, resulting in much greater instructional time in full day programs, representing approximately 40-50% more instruction in full day programs than half-day programs†. (Plucker, ii) Teachers also have the benefit of getting to know the students and their parents better. According to Dr. Martinez, â€Å"Teachers state that they have a chance to know children and parents better, to do more individualization of instruction, and to expand the curriculum horizontally. (Dr. Martinez) There are so many benefits for the children. A very important benefit is that the full day kindergarteners have the opportunity to an easier transition into the first grade because they are already used to the full day schedule. The time that the students get to spend with the teacher is a great benefit as well. The extra time that is spent with the teacher is as much beneficial for the teacher as it is for the students. According to the research from Dr. Martinez, â€Å"Teachers thought children developed closer relationships and were more relaxed in the full-day program and felt more a part of the school. Teachers indicated they were able to give more individual attention to students and that children had more time to develop both academic and socialization skills. Teachers noted they could work more on the continuing development of each child and felt children showed more advancement. Teachers indicated they felt closer to the children and that they got to know both child and family better. Some indicated in the full day they felt more flexible, were more relaxed and spontaneous, and felt better prepared to meet with parents. † (Dr. Martinez, 6) The time that the students get to spend on activities is another great benefit. According to NEA, â€Å"in a study evaluating teachers’ views on full-day kindergarten, teachers reported a number of benefits for themselves as well as children and parents. Participating in full day eased the transition to first grade, helping children adapt to the demand of a six-hour day. Having more time available in the school day offered more flexibility and more time to do activities during free choice times. Having more time actually made the kindergarten program less stressful and frustrating for children because they had time to fully develop an interest in activities. Participating in he full-day schedule allows more appropriate academic challenges for children at all developmental levels. Children with developmental delays or those at risk for school problems benefited from having more time to complete projects and more time for needed socialization with peers and teachers. † (NEA) Full day kindergarten offers more benefits to the students that are at risk and children that come from educational and economical disadvantaged homes. If the full day kindergarten programs cost money, as most do, they cost around 3000 dollars per child for the year. The 3000 dollars is charged to the parents of the child. The children that come from the educationally and economically disadvantaged homes would not be able to attend because of the cost. These children are the ones that benefit from the program the most. According to the Indiana Superintendents, â€Å"Students at or below the poverty level enrolled in full day kindergarten scored statistically significantly higher in math and reading than their half day counterparts. Poor children enrolled in full day kindergarten programs tested statistically significantly above half day pupils on reading, spatial, and verbal skills, naming colors and letters, and identifying numerals. (Plucker, 6) Parents prefer full day kindergarten as well. I as a mother prefer the full day kindergarten program to the half-day program. One of the advantages is that I do not have to figure out childcare and who would bring my son to the childcare. Trying to figure out childcare and school between my job schedule would be undesirable. As said by Dr. Martinez, â€Å"Full-day kindergarten saves parents day-care problems, while providing children a comprehensive, developmentally-appropriate program. Parents said that children often feel more stress when they have to go from a school situation to a day-care environment, where different rules and philosophies apply. Therefore, parents favor a full-day program, which reduces the number of transitions kindergartners experience in a typical day. † (Dr. Martinez) Full day kindergarten also takes a huge cost out of many parents’ monthly budget including mine. Even though some people would be against this and say, â€Å"Why would I have to pay for your childcare? † I would say that many parents including myself pay taxes too. Their parents wanted them to have the best education that they could have gotten. Most importantly, I know that my son and many other children are getting the best out of their day while they are in school. They are having fun while they are learning. My son enjoys being in school. If he had a choice, he would go on Saturdays and Sundays. Children attending full day kindergarten spend the day learning instead of watching television or playing video games. Full-day kindergarten provides parents with better support for their children. According to NEA, â€Å"For parents who work outside the home, full-day kindergarten means that children do not have to be shuffled between home, school, and childcare. For all parents, there is more continuity and less disruption in the child’s day and more time for focused and independent learning. One study of parent attitudes found that after the second year of a full-day kindergarten program, 100 percent of full-day parents, and 72 percent of half-day parents noted that, if given the opportunity again, they would have chosen full-day kindergarten for their child†. (NEA) In conclusion, having full day kindergarten should be mandatory. There are many benefits of the full day kindergarten program. The benefits are not limited to the students. Teachers and parents also get great benefits out of the full day program. According to MaryBeth, â€Å"Research has shown that it is important to begin learning early in life. School systems that have implemented the academically based full day kindergarten are finding it to be successful. If I had to choose again if a child of mine was going to go to full day or half-day kindergarten, I would not even have to think twice. A child’s education should be one of the most important things to think about. These children will be the future and they need a great education to get there.

Old People Essay Example for Free

Old People Essay Nepal, being a village-dominant country has almost quarter of its population comprising older people (60+ age group) according to the census report and it is found that the population of older people is gradually increasing. The 60+ aged group people are called dependant and inactive people . Elder people are a vital part of the society where we live in. But it is also a bitter truth that older people are not treated well so far in the family or in a society at present context. The world is dynamic or changeable. We all become old after definite period of time. This is continuous and natural process. In fact, when a man grows older, he/she becomes physically as well as mentally helpless and week. As a result, his/her working capacity gets decreased physically. It is beyond a mans control to grow older. As Nepal, a developing country is moving along with this ever changing and inevitable modernization at great speed, it is neglecting the fact that elder people are to be respected. Obviously, older people are much more experienced about the most things we talk about in our daily lives. They had lived their life through many ups and downs than we, so called modern human have done so far. We might call ourselves a literate and modern people but do keep in mind that only getting multiple degrees do not make a man wise, honest and intellectual. They (elders) might be illiterate but they have far more knowledge than us. There is the condition of being alone for the old people in todays society where people wish to have modern nuclear family. It is also due to their busy life, their dream to be rich quickly, generation gap and so on. Being a successful business man, a son doesnt like to live with his old parents. He suddenly forgets the hard labors of parents for getting their son to a boarding school, forgets the words he kept while his father walked him around carrying on shoulder about giving happiness like no one ever have imagined, forgets the warmth of his mother and that pat on shoulder of his father. He doesnt even bother to ask what his parents wish for to keep them happy. This behavior of every grown up children has compelled every old parents to enter elderly homes. So many old people having their sons and daughters in their family have to live separately. Despite having physical facilities at elderly homes, there is not emotional attachment between grandparents and grandchildren as it is experienced at homes. Old age in itself is not a problem. Peoples activities create problems for old people at this age. Due to this reason, old aged people have become a great problem in recent world. Older people are the creator of the society. Social and cultural traditions area transmitted to new generation by them. They do have their needs and wishes. They also have the right to live their life comfortably. Society as well as country should address this issue as the first priority. But foremost each individual must be aware about treating elder people. Academic courses should be provided with the roles importance of elder people in the society. Elder people when given suitable opportunities can be creative. We have read many great novels, literatures written by senior citizens. They should be motivated in doing productive works during their leisure time. Families play an important role. Most elders live their life alone doing nothing at all but instead they should be made socially active so that they can share their views among others. As older people becomes physically weak, they should be provided nutritious balanced diet, their health should be checked up time and again, they should not be involved in hard work, etc. Change is inevitable and it should start from us and since, Action speaks louder than words, our good act will lead to success.

Examination Of The Motifs In Till Eulenspiegel Music Essay

Examination Of The Motifs In Till Eulenspiegel Music Essay After an unsuccessful premiere of the opera Guntram in 1894, Strauss was consistently looking for new material for an opera. It appears he became more concrete about plans for an opera after finding the Eulenspiegel material from the chapbook Ein kurtzweilig lesen von Dyl Ulenspiegel [an amusing reading of Dyl Ulenspiegel] from 1515. The opera libretto for Till Eulenspiegel remained only a sketch, but the symphonic poem became a triumph. Franz Wà ¼llner conducted the premiere in November 1895. He asked Strauss for a few programmatic explanations, but the composer restricted himself to enunciating the two Eulenspiegel themes at the beginning. Further, he said that it would be impossible to produce a programme for Eulenspiegel. So this time we will leave the audience to crack the nuts themselves the rogue hands out to them. 615. Up that ladder. See him hang, he is running out of breath, one last convulsion. Till, the mortal, is no longer In my work I have decided to focus on Till Eulenspiegel ´s melodic motifs and their interpretations presented by Mathias Hansen, Thomas Armstrong and Michael Kennedy (see bibliographical references at the end). I have compared and examined them in reference to points on which they agree or disagree and I have integrated my own ideas by implying text to the score. In the first few bars we can find disagreement between the different observations. Mathias Hansen writes that the six introductory bars do not play a role until the epilogue in bar 633. It is true that this introduction does not take over the function of a ritornello in the sense of a Rondeau, but I disagree with the claim that this once upon a time theme has a separate status in the story. The opening phrase is in a folk-lore character taking as back to the times when Till was a historical figure. The first half of Tills theme, starting in bar six, is hesitant, however the second, identical entry is confident and self-assured, as if Till was checking the scene before appearing. Das war ein arger Kobolt wrote Strauss himself under this phrase (He was a wicked Goblin) and the above musical example portrays Till according to Strauss description. Thomas Armstrong notices that prologue is based on the second Till theme in bar 46/47: By writing this theme in its simplest form, we can easily detect that the prologue is a conclusion of it: Hansen also notices the Till-chord, which is the dominant chord in bar 47/48 (related to C and leading to the F home key); further on, he shows the relationship between this chord and the Tristan-chord: written in another tone or interval position, the harmony of the Till-chord corresponds with the one from the Tristan-chord. Strauss: Till EulenspiegeWagner: Tristan und Isolde The section between bars 51 -111 Strauss uses for exposition of the Till themes. One interesting thing is noticed by Armstrong, who shows the appearance of the wicked goblin theme in bar 53, starting with the clarinet and continuing with the first violins, further developments takes place in bassoon and lower strings part. Hansen also refers to these theme in his observation on bar 63 (et sqq) where a compressing through a massive overlapping of the first part of the wicked goblin theme takes place. Hansen writes that the passage from bar 46 et sqq. is dominated by one motif Regardless of its meaning, it [material compression] tries to integrate approximately every note in the context relating to motifs. Such complexity, that tries to dissolve the contrast of primary and secondary material, of foreground and background of a piece, is emerging emphatically in Strausss way of composing Till  [1]  . Hansens dissolving of foreground and background material might be suitable for the passage he is describing; however, if we think of Strausss Don Quixote, which was written two years after Till, we can find a quite clear separation of primary and secondary material. Strauss even assigned the characters of the piece to instruments: there is Don Quixote, who is represented by the solo cello and his squire Sancho Panza, who is described by the solo viola and the bass clarinet. In Till Eulenspiegel the whole passage from bar 46 to bar 134 includes figures that imply use of verbal text; this musical narration finds the words and their meaning in the actual notation of the music; e.g.: Bar. 71 et sqq.: Till is ready for his first prank Bar. 81-85: But when? But where? Bar. 98 et sqq.: Tills zest for action Bar. 105-109: Till is thinking of a crude prank Bar. 111 133: Just you wait you bootlicker! War ten mal! (just you wait) This is when the first true episode takes place. Clarinets rush upwards, cymbal clashes and Till mounts a horse andà ¢Ã¢â€š ¬Ã‚ ¦jumps! (137et sqq.) Riding roughshod through the market square as the beginning is presented in the string section: Strauss noted down in the score Away in seven-league-boots for bar 151 and 152 notes that depict that theme are assigned to the flutes, the oboes and the clarinets and refer these two bars to the first part of the wicked goblin theme. There is a pause in bar 154 when Till hides himself in a mouse-hole and carefully puts out his head. Armstrong explains the pause in bar 154 with the words: Till seems to be lost. I would rather say that the break has the character of Phew that was a near thing! Starting from bar 157 until 169 Till is again in the heart of a new adventure. Strausss note on that passage: He emerges in disguise as a priest, oozing unction and morality lets us expect a musical caricature. On the contrary, whatever the clarinet, the bassoon and the violas play in a folksong-way of simplicity it has nothing to do with open mockery or cautious irony. The repeated inclusion of the first part of the wicked goblin theme does not radiate the effect of a caricature. With his note The knave peeps out of [his disguise] at the big toe, Strauss must have meant the figure in bar 191: It is when D clarinet presents Tills second theme revealing who is under preacher disguise! The chromatic runs of the horn, trumpets and violins (bars 196 198) show how dangerous Tills practice of mocking religion is at that moment. 9 bars later a glissando in solo violin opens another adventure: Bar. 209 et sqq.: Till the cavalier, exchanging sweet courtesies with beautiful girls Tills horn theme is presented in a romantic way Till felt in love with one of the girls and the music is coated with harmonically richer material. When Till is mistreated by the girl, his themes stomp through the orchestra until the four horns seem to be shaking their fist at the world and this is when in bar. 287 288: He [Till] vows he will take revenge on all mankind The most promoted part of the tone poem starts here (bar 293 et sqq.). Strauss brings the rhythmical energy of the motifs into play. Till is amongst the Philistines whose motif is played by bass clarinet and four bassoons (bar 293 299). Tills horn motif is now played by strings as if Till was asking the pedagogues his questions; this is how Strauss puts it: After he has posed a couple of atrocious theses to the philistines, he leaves them to their fate dumbfounded. The music of this section portrays pointlessness of pedagogues calculations; They have been cornered by Till and left puzzled. Concerning the Philistines, a series of variations develops, in which the formative force is in the rhythmical richness of creation, some of them are composed as canonical variations: In the following passage Strauss tries to create a deceptive silence after the council of the Philistines decided to end Tills days. Till is waiting cautiously for revenge, he takes advantage of this situation and does more and more mischief, rather than trying to become an ordinary citizen. The first Till theme sounds again, Till reappears first in first horn in F in bar 429, then in bar 436 horn in D presents Tills theme enriching the tonality. Starting in bar 429 (et sqq) Till appears again for new pranks and these know no bounds anymore. Consumed by disappointments, he does not appear as a harmless humorist, but as a revengeful human being in a fools costume. It gives a feeling of wildness and in this broadening atmosphere Strauss develops an intensity and complexity of motives combinatory that is difficult to beat. Armstrongs description is also in this direction: The music is keyed up to a higher pitch of excitement than ever. Tills last stretch of development, some 140 bars in length, shows Strausss music in full and unhesitating flight.  [2]   Trying to describe this long passage, I would put the following words: Bar 410 to 429: There is a deceptive silence From bar 486: Till is very successful From bar 546 Till gets up to more and more mischief, he becomes more high-spirited, livelierà ¢Ã¢â€š ¬Ã‚ ¦ à ¢Ã¢â€š ¬Ã‚ ¦and even daredevil (bar 555 et sqq.) He feels like the lord of the world, even a god! (Bar 567 et sqq.) Fanfares in trumpets and horns: Straus puts an extra emphasis on this passage by expanding the brass section by three trumpets and an optional second quartet of horns. The boldness and arrogance of Tills behaviour is growing. He gets arrested and faces judges accusations (bars 573 581) accompanied by violent side-drum roll that lasts for fifteen bars. Till wants to keep his nonchalant attitude but starts to realize he has gone too far. The biggest penalty is given pictured in music by second Tills theme instrument D clarinet playing upward notes falling into major seventh chord (bars 615 616), when Till is going up the ladder to be hanged. This is when D clarinet reaches its highest A flat, holding it awhile and starts to move down, accompanied by the flute-trill (bars 619- 620) that describes Till running out of breath. This passage does not only sound like a sharp cry, though, it also portrays the breathlessness of Till. None of the authors specifies the epilogue. Kennedy refers the epilogue to Till himself: A gentle epilogue recalls the works fairy tale opening, as if to remind us, before he scampers away, that Till was not such a bad fellow.  [3]   Armstrong writes similarly: It is Tills characteristic tune with the devil taken out of it, so that it seems almost tender. This epilogue shows the composers insight at its keenest  [4]  . The epilogue recalls and extends Once upon a time version of Tills second theme (bar 632 et sqq). The atmosphere is similar to the one from the opening of the piece with it folk-lore narration and charm. In my opinion, Strauss composed the following content: Once upon a time, there was a foolà ¢Ã¢â€š ¬Ã‚ ¦he diedà ¢Ã¢â€š ¬Ã‚ ¦but through this story, he is still alive. Hansen and Werbeck have differing opinions about the form of Till Eulenspiegel. Hansen describes the form as follows: Basically, there are only two central events, and they are actually a combination of theme and motif those two of the hero, of which Strauss informs Wà ¼llner in his letter  [5]  . Walter Werbeck tries to explain the form more accurately: Strauss composes neither an authentic sonata rondo nor a traditional rondo chain  [6]  . The element of a rondo that is missing is ritornello, but if we see rondo as representation of two themes then we might be dealing with a variant of rondo in Till Eulen spiegel. Walter Werbeck continues: One could easily describe the first part of Till as a free variation form, or, preferably, as a form in which rondo and variation are combined as follows: A (Exposition); Aà ¢Ã¢â€š ¬Ã‚ ² (market scene, variation 1); B (sermon scene, episode 1); A à ¢Ã¢â€š ¬Ã‚ ²Ãƒ ¢Ã¢â€š ¬Ã‚ ² (love scene, variation 2); and C (Philistines, episode 2). Strauss also drew on principles of sonata form. As evidence we might cite especially the emphatic recapitulation of the initial horn theme in bar 429 that opens the second part of the piece.  [7]   Both Hansen and Werbeck divide the piece in the same way into two main parts. Whereas Hansen only tells us approximately where his second part starts, Werbeck gives us the exact bar number (429) of his division. Hansen is content with the division into two central events; Werbeck, however, tries to show that Till is undoubtedly much more than a sonata rondo. The composer combines sonata form, variations and rondo. These forms cannot be seen separately they overlap and penetrate each other to varying degrees. At some points the form of a set of variations dominates, sometimes as sonata or as rondo. Warbecks quotation As Till Eulenspiegel, the protagonist of the tone poem, resists societal norms by mocking them with continuous pranks, so does the composer thwart the expectations of those who want to pin him down to the norms of a rondo  [8]   seems to be especially appropriate here. Trying to fit Till into a rondo form, the following division makes sense: 1. Prologue and Exposition; bar 1-111, the fool is introduced 2. Variation I; bar 112-178, the upsetting of the market place 3. Episode I; bar 179-206, the mockery of the sermon 4. Variation II; bar 207-288, Till in love 5. Episode II; bar 289-409, the confusing of the professors 6. Recapitulation (Variation III); bar 410-594, Till goes on his way 7. Coda (Episode III); bar 595-632, Till is arrested and hung 8. Epilogue; bar 633-658 At this point I would like to summarise the themes of Till Eulenspiegel: The wicked goblin theme and its modifications: BASIC FORM: NARRATIVE: AS A CAPER: HE LIES IN WAITING AT A GALLOP RELIEVED, AT A SAFE PLACE IN LOVE AS AN OATH OF REVENGE IN A CONFIDENT WAY UP THE LADDER FURTHER THEMES: Till Eu len spie gel, till Eu-len-spie gel, Till Eu-len spie-gel NAMING OF TILL NEW PRANKS IN LOVE COURTING AGAINST THE PHILISTINES DECEPTIVE SAFETY MISCHIEVOUS Richard Strausss Till Eulenspiegel appears as a masterpiece in composers career. In this piece Strauss used yet the biggest orchestra with massive woodwind section and optional second horn quartet. It is in some way symbolical that after serious labour on Guntram Strauss composes such a spectacular work inspired only by a folk legend. Richard Strauss himself leads us well and truly to believe in something with his title Nach alter Schelmenweise in Rondeauform [after an old rascal manner in rondo form]. Whoever thinks that Strauss came to a compromise with the traditional form will notice quickly that any pattern is avoided. It is not the form of the rondo with the methodical; umpteen times reprise of the theme, the unity is reached by the consistent development of the melodical-thematical elements. These elements, which come in the most varying forms, in the bravest disguises and the rhythmical and harmonical transformations, are the two main themes. Strauss uses the specific sound character of an instrument in the score very carefully. This is what gives the whole tone poem the humorous colour. When the notes become alive, everything sounds so simple, natural and unconstrained. Strauss makes high demands on the musical intelligence of the musicians playing his works.
