Similarities and Differences between Gilgamesha dn Enkindu

Similarities and Differences between Gilgamesh and Enkindu The Myth known today as the epic of Gilgamesh was considered in ancient times to be one of the great masterpieces of cuneiform literature.The tale revolves around a legendary hero named Gilgamesh, who was known said to be the king of the Sumerian city of uruk.Gilgamesh was known to have supernatural abilities and be half human and half god similar to his best friend who was later known known as Enkindu.This person was also blessed with supernatural abilities and was half human-half animal.Gilgamesh and Enkindu both have similar traits such as they both use love as a motivating force and they both clearly are half human-half supernatural.They also have differences such†¦show more content†¦Then on page 21 Enkindu stood watch for the shepherds against the lions so that the shepherds could get a good night sleep, this protects the shepherds and feeds them. This shows the power that Enkindu has by fighting of lions, capturing wolves and keeping the shepherds safe. So basically G ilgamesh who is half human and half God, he thinks he is the most powerful person on this Earth and thinks he can do whatever he wants whenever he wants. He takes every woman there is, even the ones that are getting married. Since he is very ignorant and doesn’t care about his people, the people complained to the Gods who then create a double of Gilgamesh who is called Enkindu, who was just as smart and strong as Gilgamesh. Gilgamesh and Enkidu also had differences it seemed that they had their own journey within each other’s journey. Enkidu’s journey starts of when the prostitutes were order by Gilgamesh to go and get Enkidu. This is because Enkidu saves his former animal friends from cages. This to me to is the starting point of Enkidu journey towards Gilgamesh. This journey was mentored by the prostitute who was also the tempter. As Enkidu finds his way to Gilgamesh this starts a whole new journey.This journey was shortlived because later on as the story goes on Gilgamesh and enkindu goes on and kills both humbaba and the bull of heaven,which the godess Ishtar sends to punish Gilgamesh for spurring her advances.As a punishment for these actions,the gods sentence Enkindu

Internal Combustion Engines Essay Summary Example For Students

Internal Combustion Engines Essay Summary Internal Combustion EnginesIntroductionInternal Combustion Engine, a heat engine in which the fuel is burned (that is, united with oxygen ) within the confining space of the engine itself. This burning process releases large amounts of energy, which are transformedinto work through the mechanism of the engine. This type of engine differentfrom the steam engine, which process with an external combustion engine thatfuel burned apart from the engine. The principal types of internal combustionengine are : reciprocating engine such as Otto-engine, and Diesel engines ; androtary engines, such as the Wankel engine and the Gas-turbine engine. In general, the internal combustion engine has become the means ofpropulsion in the transportation field, with the exception of large shipsrequiring over 4,000 shaft horsepower ( hp). In stationary applications, size of unit and local factor oftendetermine the choice between the use of steam and diesel engine. Diesel powerplants have a distinct economic advantage over steam engine when size of theplant is under about 1,000 hp. However there are many diesel engine plants muchlarge than this. Internal combustion engines are particularly appropriate forseasonal industries, because of the small standby losses with these enginesduring the shutdown period. HistoryThe first experimental internal combustion engine was made by a Dutchastronomer, Christian Huygens, who, in 1680, applied a principle advanced byJean de Hautefeuille in 1678 for drawing water. This principle was based on thefact that the explosion of a small amount of gunpowder in a closed chamberprovided with escape valves would create a vacuum when the gases of combustioncooled. Huygens, using a cylinder containing a piston, was able to move it inthis manner by the external atmospheric pressure. The first commercially practical internal combustion engine was built bya French engineer, ( Jean Joseph ) Etienne Lenoir, about 1859-1860. It usedilluminating gas as fuel. Two years later, Alphonse Beau de Rochas enunciatedthe principles of the four-stroke cycle, but Nickolaus August Otto built thefirst successful engine ( 1876 ) operating on this principle. Reciprocating EngineComponents of EnginesThe essential parts of Otto-cycle and diesel engines are the same. Thecombustion chamber consists of a cylinder, usually fixed, which is closed at oneend and in which a close-fitting piston slides. The in-and-out motion of thepiston varies the volume of the chamber between the inner face of the piston andthe closed end of the cylinder. The outer face of the piston is attached to acrankshaft by a connecting rod. The crankshaft transforms the reciprocatingmotion of the piston into rotary motion. In multi-cylindered engines thecrankshaft has one offset portion, called a crankpin, for each connecting rod,so that the power from each cylinder is applied to the crankshaft at theappropriate point in its rotation. Crankshafts have heavy flywheels andcounterweights, which by their inertia minimize irregularity in the motion ofthe shaft. An engine may have from 1 to as many as 28 cylinders. The fuel supply system of an internal-combustion engine consists of atank, a fuel pump, and a device for vaporizing or atomizing the liquid fuel. InOtto-cycle engines this device is a carburetor. The vaporized fuel in mostmulti-cylindered engines is conveyed to the cylinders through a branched pipecalled the intake manifold and, in many engines, a similar exhaust manifold isprovided to carry off the gases produced by combustion. The fuel is admitted toeach cylinder and the waste gases exhausted through mechanically operated poppetvalves or sleeve valves. The valves are normally held closed by the pressure ofsprings and are opened at the proper time during the operating cycle by cams ona rotating camshaft that is geared to the crankshaft . By the 1980s moresophisticated fuel-injection systems, also used in diesel engines, had largelyreplaced this traditional method of supplying the proper mix of air and fuel;computer-controlled monitoring systems improved fuel economy and reducedpollu tion. IgnitionIn all engines some means of igniting the fuel in the cylinder must beprovided. For example, the ignition system of Otto-cycle engines , the mixtureof air and gasoline vapor delivered to the cylinder from the carburetor and nextoperation is that of igniting the charge by causing a spark to jump the gapbetween the electrodes of a spark plug, which projects through the walls of thecylinder. One electrode is insulated by porcelain or mica; the other is groundedthrough the metal of the plug, and both form the part of the secondary circuitof an induction system. The principal type of high-tension ignition now commonly used is thebattery-and-coil system. The current from the battery flows through the low-tension coil and magnetizes the iron core. When this circuit is opened at thedistributor points by the interrupter cam, a transient high-frequency current isproduced in the primary coil with the assistance of the condenser. This inducesa transient, high-frequency, high-voltage current in the secondary winding. Thissecondary high voltage is needed to cause the spark to jump the gap in the sparkplug. The spark is directed to the proper cylinder to be fired by thedistributor, which connects the secondary coil to the spark plugs in the severalcylinders in their proper firing sequence. The interrupter cam and distributorare driven from the same shaft, the number of breaking points on the interruptercam being the same as the number of cylinders. Cooling SystemBecause of the heat of combustion, all engines must be equipped withsome type of cooling system. Some aircraft and automobile engines, smallstationary engines, and outboard motors for boats are cooled by air. In thissystem the outside surfaces of the cylinder are shaped in a series of radiatingfins with a large area of metal to radiate heat from the cylinder. Other enginesare water-cooled and have their cylinders enclosed in an external water jacket. In automobiles, water is circulated through the jacket by means of a water pumpand cooled by passing through the finned coils of a radiator. Some automobileengines are also air-cooled, and in marine engines sea water is used for cooling. Christopher Columbus EssayThe exhaust gases are then expelled through an exhaust port through the actionof the turning rotor. The cycle takes place alternately at each face of therotor, giving three power strokes for each turn of the rotor. The Wankelengines compact size and consequent lesser weight as compared with the pistonengine gave it increasing value and importance with the rise in gasoline pricesof the 1970s and 80s. In addition, it offers practically vibration-freeoperation, and its mechanical simplicity provides low manufacturing costs. Cooling requirement s are low, and its low center of gravity contributes todriving safety. Gas TurbineAlso called as combustion turbine, engine that employs gas flow as theworking medium by which heat energy is transformed into mechanical energy. Gasis produced in the engine by the combustion of certain fuels. Stationary nozzlesdischarge jets of this gas against the blades of a turbine wheel. The impulseforce of the jets causes the shaft to turn. A simple-cycle gas turbine includesa compressor that pumps compressed air into a combustion chamber. Fuel ingaseous or liquid-spray form is also injected into this chamber, and combustiontakes place there. The combustion products pass from the chamber through thenozzles to the turbine wheel. The spinning wheel drives the compressor and theexternal load, such as an electrical generator. In a turbine or compressor, a row of fixed blades and a correspondingrow of moving blades attached to a rotor is called a stage. Large machinesemploy multistage axial-flow compressors and turbines. In multi-shaftarrangements, the initial turbine stage (or stages) powers the compressor on oneshaft while the later turbine stage (or stages) powers the external load on aseparate shaft. The efficiency of the gas-turbine cycle is limited by the need forcontinuous operation at high temperatures in the combustion chamber and earlyturbine stages. A small, simple-cycle gas turbine may have a relatively lowthermodynamic efficiency, comparable to a conventional gasoline engine. Advancesin heat-resistant materials, protective coatings, and cooling arrangements havemade possible large units with simple-cycle efficiencies of 34 percent or higher. The efficiency of gas-turbine cycles can be enhanced by the use ofauxiliary equipment such as inter-coolers, regenerators, and reheaters. Thesedevices are expensive, however, and economic considerations usually precludetheir use. In a combined-cycle power plant, the considerable heat remaining in thegas turbine exhaust is directed to a boiler called a heat-recovery steamgenerator. The heat so recovered is used to raise steam for an associated steamturbine. The combined output is approximately 50 percent greater than that ofthe gas turbine alone. Combined cycles with thermal efficiency of 52 percent andhigher are being put into service. Gas turbines have been applied to thepropulsion of ships and railroad locomotives. A modified form of gas turbine,the turbojet, is used for airplane propulsion. Heavy-duty gas turbines in bothsimple and combined cycles have become important for large-scale generation ofelectricity. Unit ratings in excess of 200 megawatts (MW) are available. Thecombined-cycle output can exceed 300 MW. The usual fuels used in gas turbines are natural gas and liquids such askerosene and diesel oil. Coal can be used after conversion to gas in a separategasifier. Internal-Combustion Engines and Air PollutionAir pollution from automobile engines ( smog ) was first detected about1942 in Los Angeles, CA. Smog arises from sunlight-induced photochemicalreactions between nitrogen dioxide and the several hundred hydrocarbons in theatmosphere. Undesirable products of the reactions include ozone, aldehydes, andperoxyacylnitrates ( PAN ). These are highly oxidizing in nature and cause eyeand throat irritation. Visibility-decreasing nitrogen dioxide and aerosols arealso formed. Five categories of air pollutants and percent contribution from alltransportation source and the highway vehicle subset are show in Table -1. Virtually all of the transportation CO, about half the hydrocarbons, and aboutone-third of the nitrogen oxides come from gasoline engines. Diesel enginesaccount for the particulate. Emissions from internal-combustion engines include those from blowby,evaporation, and exhaust. These can vary considerably in amount and compositiondepending on engine type, design, and condition, fuel-system type, fuelvolatility, and engine operating point. For an automobile without emissioncontrol it is estimated that of the hydrocarbon emission, 20 to 25 percent arisefrom blowby, 60 percent from the exhaust, and the balance from evaporativelosses primarily from the fuel tank and to a lesser extent from the carburetor. All other non-hydrocarbon emissions emanate from the exhaust. At least 200 hydrocarbon (HC) compounds have been identified in exhaust. Some such as the olefin compounds react products. These are termed reactivehydrocarbons. Others such as the paraffin are virtually unreactive. Special DevelopmentsThe Stratified-Charge Engine a modification of the conventional spark-ignition piston engine, the stratified charge engine is designed to reduceemissions without the need for an exhaust-gas recirculation system or catalyticconverter. Its key feature is a dual combustion chamber for each cylinder, witha prechamber that receives a rich fuel-air mixture while the main chamber ischarged with a very lean mixture. The spark ignites the rich mixture that inturn ignites the lean main mixture. The resulting peak temperature is low enoughto inhibit the formation of nitrogen oxides, and the mean temperature issufficiently high to limit emissions of carbon monoxide and hydrocarbon. Two rather distinct means for accomplishing the stratified chargecondition are under consideration :1. A single combustion chamber with a well-controlled rotating airmotion. This arrangement is illustrated (Fig.6) by the Texaco Combustion Process(TCP), patented in 1949. 2. A prechamber or two-chamber system. This is illustrated by Fig.7,which shows the general arrangement of the Honda Compound-vortex controlled-combustion (CVCC) system. For both systems, very careful development has proved to be necessary toobtain complete combustion of the fuel under the wide range of speed and loadconditions required of an automotive engine.

The Role Of Technology Essay Research Paper free essay sample

The Role Of Technology Essay, Research Paper Man is still the most extraordinary computing machine of all. John F. Kennedy Speech, May 21, 1963 As we look back in retrospect, civilisation has evolved greatly from coevals to coevals. Our promotion has been entirely dependent on one factor, the human head. The human head has brought us from the bondages of Neanderthal epoch to today s modern age. It has brought us legion of comfortss that are every bit simple as a cock to every bit sophisticated as the personal computing machine. These creative activities have multiplied exponentially and have been the crutch for our society. The anxiousness of Y2k exemplifies the magnitude in which we rely on these machines we have created. The quandary in which the development of engineering brings is a simple inquiry: To what extent should these machines govern our lives? This medium is the important reply to future endurance of our being. We will write a custom essay sample on The Role Of Technology Essay Research Paper or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page If we look back to a small over two centuries ago in our universe, engineering was non every bit outstanding as it is now. A twenty-four hours in which the Equus caballus cart broke did non greatly affect day-to-day life for people in that clip period. On the other manus, conceive of a twenty-four hours when electricity stops. Airports would be shut down, communicating failures, concern loss, and etc. Recently an temblor hit the state of Taiwan, where a bulk of the semiconducting material industry is located. During the temblor with a Richter graduated table of 7.4, many of the mills halted production on computing machine french friess. In the one of two yearss the workss were shut down, stocks associating to the computing machine industry plummeted. Dell Computer announced that its 3rd one-fourth net incomes would be lower than outlooks, Gateway portions dropped, and the harm went down the concatenation to companies that were related to the computing machine industry. If the craze o ver Y2k is accurate, we will see in first manus, the appreciation in which engineering has on our society. I have observed that a popular secret plan in sci-fi novels is the impression that someday in the hereafter, computing machines will regulate our lives and we will go slaves to them. The Terminator film series is a authoritative illustration that uses this secret plan. One must inquire himself if this fiction has become a world for worlds. Weapons of mass devastation were a changeless fright for all citizens during the Cold War and are still a menace to us. Reading about the Oklahoma City bombardment, the Columbine shots, the recent Xerox shots, and so forth makes me inquire if we have become slaves to our creative activities. To happen the medium in which we can equilibrate engineering with our lives, we must understand the differences and analogues that computing machines portion with us. An evident disparity is that computers/machines do non posses the ground and intuition that a human encephalon contains. Descartes foresaw this differentiation and grounds as follows: For whereas ground is a univeral instrument which can be used in all sorts of state of affairss, these variety meats [ of animate beings, like mechanisms in general ] need some peculiar temperament for each peculiar action ; hence it is for all practical intents impossible for a machine to hold adequate different variety meats to do it move in all eventualities of life in the manner in which our grounds makes us move. ( Descartes 1637, p.140 ) Descartes continues, even though such machines might make [ or state ] some things every bit good as we do them, or possibly even better, they would necessarily neglect in others, which would uncover that they were moving non through understanding but merely from the temperament of their variety meats. There is a common misconception that computing machines are perfect in their several maps and that they are the solution to the erroneous human being. Therefore, we trust it with all of our day-to-day responsibilities. Many continue to believe that since computing machines appear to be perfect and that we trust it with all our responsibilities, finally computing machines are smarter than worlds and someday may assist us carry through all of our undertakings. We have been fascinated by the capablenesss of the new cheat title-holder, Artificial Intelligence. The fact of the affair is that Artificial Intelligence can be flawed merely like worlds can be. The Chinese Room Argument proposed by John Searle gives us a glance to the abilities of AI. The experiment requires puting individual in a room with a clump of Chinese Hagiographas. Based on the batches of direction they give you are required to decode the Chinese characters. This carbon monoxide rrelation is evidently impossible to most existences and one of Searle s decisions is: If he doesn t understand so there is no manner the system could understand because the system is merely portion of him. Behind every computing machine system or package lays a plan or codification that was created by a human being. Therefore if you believe that worlds are erroneous, so the plans created would be besides flawed sharing a analogue between machines and worlds. In order to find whether to choose the consequences from the computing machine or the ace sawbones as given in the scenario, the benefits and disadvantages of computing machines must be underlined foremost. In the paragraphs above, I have tried to happen grounds to confute the impression that computers/machines are unflawed. However, computing machines can go a great complement to our day-to-day undertakings. The quandary we face is how much or how small we should trust on engineering before it controls us. The medium is simple ; blend the best of what worlds may offer such as the flexibleness of our heads with the increased truth and efficiency of the computing machine. In this given scenario, the computing machine that predicts the possibilities of a bosom onslaught should be viewed as a 2nd sentiment. Each bosom onslaught instance varies from patient to patient, computing machines may be accurate most of the clip but on the rare occasions it may besides be incorrect. Merely a phys ician would be able to take in history particular conditions such as a rare bosom status or a phenomenon that was neer discovered. The computing machine on the other manus would either give a false end product or syntax mistake. With the benefits of a physician and the computing machine as a 2nd sentiment, the patient would so be able to do an informed determination. However, if we become wooed by the computing machine s ability to do these anticipations and hope to replace physicians someday with these devices, we so cross the thin ruddy line from utilizing it as a tool to trusting on it. Promotions in the medical field have made medical specialty pattern today, more efficient and accurate. Inventions such as the X ray have become tools or nurses for physicians. Yet with these comfortss, most physicians do non trust entirely on generated informations but besides their experience and cognition learnt making a balance between adult male and engineering. Most resistance on this affair will reason on the virtue of a few points. First and first, cost efficiency ; if we are able to change over computing machines into physicians someday imagine the reduced cost of medical advice. There would be an obvious demand for these devices and therefore driving down the monetary values for medical attending. Peoples from all fiscal backgrounds would eventually be able to afford some kind of medical advice since surgery and advice presents have become extortionate in their costs. Second, this new signifier of medical specialty is clip efficient every bit good. Alternatively of leaping from physician to sophisticate for secondary sentiment, one computing machine will bring forth the same consequence as the other devices. Third, the computing machine may be able to give a more accurate diagnosing a individual physician today without the 2nd sentiments. However, there are many ethical issues that are involved in this state of affairs. Computers will n on be able to observe any new signifiers of diseases or rare conditions therefore giving many lives. My attack to this quandary from the article in the New Yorker is straightforward. I would take into consideration what the physician informs me of and besides the statistical informations compiled by the computing machine. However, I would non trust entirely on the computing machine but besides 2nd sentiments from other heart specialists besides the primary 1. Statistically wise, if I sought out three physicians and all three said I was all right and healthy. I would take their word for it and overruling the consequence generated by the computing machine. However, if the other two physicians agreed with the computing machine my obvious pick would be to understand that a bosom onslaught might happen. The most critical component I believe in this quandary is non to trust on engineering itself. The head is far more complex than computing machine french friess that were made by worlds. If the gift of our head were compromised, so they would be apparently no demand for them. Where there is the necessary proficient accomplishment to travel mountains, there is no demand for the religion that moves mountains. Eric Hoffer Man must understand its function with engineering before any continual patterned advance or else the sci-fi books we read may someday go a world.
