Jeep Marketing Project essays
Jeep Marketing Project essays Executive summary and the history of jeep: The jeep has first appeared as a World War II military vehicle. The 4-wheel-drive jeep helped popularize a new era for sport utility vehicles. It is well known with fun and adventure and is one of the most widely recognized brands in the world. Although there is no definite knowledge of how the "Jeep" got its name, however, some theory claims that Jeep name came from G.P. for General Purpose vehicle, which is designed for army vehicle.(4 and 6) There are three classifications for jeep: Jeep Grand Cherokee, which is the new level of technological innovation. It has the new modification of Jeep Cherokee. It is one of the best four-wheel-drive cars that is designed for the best handling, and the finest refinement and style. Jeep Cherokee is the original four-wheel sport-utility vehicle. It has a top performance capability. Jeep Wrangler is the conqueror of both battlefield and off-highway adventures. The icon of the jeep brand. Wrangler is still the original 4WD fun and freedom machine. The new wrangler's wide appeal has much to do with its three models: The value leading SE, the mid-level Sport, and the well-equipped Sahara. Wrangler is still the heart and soul of the jeep brand. Wrangler continues its impressive sales history with 68,619 units sold in the 1995 model year. While its closest competitor held 29 percent (Geo Tracker) and 10 percent (Suzuki Sidekick) of the 1995 mini sport utility sales, Wrangler dominated the category by attracting 48 percent. With the functional and design improvements of the all-new model, sales should continue to be strong.( 2 and 3) also ( Refer to appendix 1 and 2).

One day in the life of Ivan Denisovich essays
One day in the life of Ivan Denisovich essays Solzhenitsyn, Aleksandr Isaevich. One day in the life of Ivan Denisovich, New YorkPress, 1963. The novel, A Day in the Life of Ivan Denisovich is intentionally not sensational. It is an expose of Stalinist labor camps, and of the Soviet system generally, but it accomplishes this through understatement and indirection. This work, however, is much more than a political indictment. Its power derives from its depiction of a man retaining his humanity under inhumane conditions. Shukov is not a heroic figure, but he wins our admiration for his cleverness, his endurance, and his simple integrity. This novel also shows a nice cross section of how soviet life was. It shows how citizens in Russia really had no freedom to speak thier mind. Solzhenitsyn who had to endure the harsh reality of labor camps himself, gives a good recount of the harsh brutalness of just one of the soviets controlling machines. Through Shukov, Solzhenitsyn suggests that there are certain qualities which must be retained no matter what the circumstances if we are to maintain our humanity. Primary among these is self-respect. Shukov works constantly to increase his odds of survival, but there are definite things, lying and begging among them, which he will not do. The novel concentrates on one man, Ivan Denisovich Shukhov, as he attempts to survive another day in a Soviet concentration camp, or gulag, with dignity and humanity. The conditions of the camp are harsh, reflecting a world that has no tolerance for independence. Camp prisoners rely almost totally on each other's productivity and altruism, even for the most basic human need, food. The dehumanizing atmosphere of the gulag ironically forces prisoners to discover means to retain their individuality while conforming to the stringent rules, spoken and unspoken, of the camp. The characters in Ivan Denisovich bring a liveliness to the novel. The narrator Ivan Denisovich is bo...

Argumentation Based on Marx's Communist Manifesto Essay
Argumentation Based on Marx's Communist Manifesto - Essay Example Modern industrial society is typified by class struggle between those who own the factors of production and proletariat. However, the influence of capitalism has been on the decline and is ceasing to be compatible with this exploitive relationship. Therefore, those who provide labor will lead to a revolution. This revolution will be different from the previous one. This is because in this revolution the proletariat will have to destroy all ownership of private property. In turn, this will lead to a complete overhaul of the classes eventually disappearing. The manifesto argument is that this development is unstoppable, and capitalism will inherently collapse. As a result, the communist engages in promoting revolution, and this will ensure that those involved are able to move history towards its natural conclusion. They concur that the elimination of social classes cannot take through reforms or changes in government. They know that such fundamental changes can only take place through a revolution. The Communist Manifesto was a plan by Marx and Friedrich Engels. They argue that for changes to take place in both society and political institutions it must be driven by a process of universal struggle on parts of groups of people with similar economic fate in order to realize their material or economic interests (Marx-Engels Archive 1). These struggles as shown in the history have been struggles of economically inferior classes against economically dominant classes who are against their economic interests (Marx-Engels Archive 1). This process has shaped the currently industrialized world: the bourgeoisie in its struggle against the aristocratic class of feudal society (Marx-Engels Archive 1). This has been heightened through travel to different parts of the world, and the discovery of new products and goods that created rooms for commercial activities. This is because the bourgeoisie whose purpose is to accumulate managed to grow wealthier and became politically embo ldened against the feudal order. In fact, the bourgeoisie has uplifted their authority to a stable entity in the society and drives various sector of the economy in pursuit of their interests. The interest of accumulation by the merchants has assured them to overcome the globe. They have forced almost all to adopt the capitalist mode of production. On the other hand, the bourgeois has fundamentally altered all aspects of the society, even the families and hence substituted rural civilization with enormous cities. Through industrialization, the means of production and exchange that drives this process of expansion and change have resulted in a subordinate class whose fate is determined by the bourgeoisie (Marx-Engels Archive 1). This class is the proletariat, and they have been uprooted by capitalism and hence are forced to sell labor to the bourgeoisie. This offends them as they remember how before they possessed and sold what they produced (Marx-Engels Archive 1). They face exploit ation and are forced to compete with one another for forever-shrinking wages as a means of production becomes more complicated. However, the workers will become enlightened and unite to fight their common enemy: the bourgeoisie. Furthermore, they will cooperate with an increasing number of the middle class whose source of livelihoods keep on dwindling due to large factories owned by a shrinking number of superrich industries (Marx-Engels Archive 1). The bourgeoisie will eventually be the author of their own downfall.Ã

Stained Glass Research Paper Example | Topics and Well Written Essays - 1250 words
Stained Glass - Research Paper Example However, it was during the Middle Ages or Medieval Period from 500 AD to 1450 AD, that the art of creating stained glass was developed in Europe. Thesis Statement: The purpose of this research paper is to investigate stained glass, its background, Medieval stained glass, the process of creating the art pieces, developments, later stained glass, and the significance of the art in the modern world. The beauty of stained glass is magical, even before it is cut and pieced together into a project. Stained glass falls into two general categories: cathedral and opalescent or opals. Cathedral glass includes all clear and transparent colored glass. Contrastingly, opalescent glass is developed from a material that crystallizes the glass during the cooling process. This results in glass ââ¬Å"with varying degrees of oqaqueness that refletcts light rather than transmitting itâ⬠(Stevenson 8). The term stained glass is considered to be a misnomer, since staining is only one of the techniques of coloring used, and the best medieval glass did not employ this method. In ancient times, Muslim designers in East Asia fitted small pieces of colored glass into intricate window traceries or lacy openwork, made of stone, wood, or plaster. This type of window mosaic continues to be used. In the windows of Christian churches, colored glass was used as early as the 5th century, and pictorial glass as early as the 10th century (The Columbia Encyclopedia, 2009). In stained glass, color has been associated with emotions, through history. After entering a church, the meditative feeling that an individual gets is partly due to the interior lighting. It is believed that the rich reds and brilliant yellows traditionally used in stained glass evoked certain emotions in the viewers. Further, since many people were illiterate, books were not read to a great extent. Thus, they also

The Yellow Wallpaper Essay Example for Free
The Yellow Wallpaper Essay Throughout the study of literature, it is believed that most works cannot be fully understood without a biographical strategy. In order to understand a work, the reader must understand the authorââ¬â¢s life and experiences to grasp the full concept of that work. In Charlotte Perkins Gilmanââ¬â¢s short story ââ¬Å"The Yellow Wallpaper,â⬠Gilman uses symbolism, personification, and other literary tools to portray the way women were treated throughout this particular era. Gilman also uses a romanticism approach when writing ââ¬Å"The Yellow Wallpaperâ⬠. The narrator believes that the woman trapped in the wallpaper, symbolizes her and all the other women living in the male dominant society. Romanticism represents an art for arts sake. Born in 1860, Charlotte Perkins Gilman was forced into an era of male supremacy. Gilman was abandoned by her father from infancy and often left into the care of relatives including Harriet Beecher Stowe and feminist activists, Isabella Beecher Hooker and Catherine Beecher. Strong and influential women, struggling for their place in a male dominant world, shaped Gilmanââ¬â¢s childhood. The women made Gilman an independent young lady, teaching her importance of exercise and philosophy, over that of clothes and jewelry. At the age of 24, Gilman married her first husband, Charles Walter Stetson. After having her daughter the next year, Gilman went into a deep depression. The noted neurologist, S. Weir Mitchell, examined her. He told her to follow his ââ¬Ërest cureââ¬â¢ of complete bed rest and limited intellectual activity. This meant no writing. Gilman realized that this ridiculous cure was actually driving her more insane, so she removed herself from Mitchells care. When her health got better during a trip to California she paired her emotional problems to her marriage and decided to leave her husband. In 1900, Gilman married for the second time to her cousin George Houghton Gilman. Gilman continued her feministic journey until discovering she was diagnosed with Breast Cancer. She left a final note that read, ââ¬Å"When one is assured of unavoidable and imminent death, it is the simplest of human rights to choose a quick and easy death in place of a slow and horrible one. Charlotte Perkins Gilman took her life on August 17, 1935, in Pasadena, California, at the age of 75. Gilmanââ¬â¢s main intent in ââ¬Å"The Yellow Wallpaper,â⬠is to portray the way women were viewed and treated during this time period. In the later 19th century, men were the superior race. Women oftentimes went from being born into a house with a father; to being married off to someone they werenââ¬â¢t exactly happy to be with, leaving no time for a woman to experience life without someone ââ¬Å"in-chargeâ⬠of them. Gilman did not want to be like other woman of this time, she redefined womanhood, proclaiming that men and women were to be equal. This ââ¬Ënew womanââ¬â¢ was to be an intelligent, well-informed, and well-educated free thinker, the creator and expresser of her own ideas. She was to be economically self-sufficient, socially independent, and politically active. She would share the opportunities, duties, and responsibilities of the workplace with men, and together they would share the solitude of the hearth. Finally, the new woman was to be as informed, assertive, confident, and influential as she was compassionate, nurturing, loving, sensitivea woman of the world as well as of the home. Gilmans vision of an autonomous female challenged not only the traditional cult of true womanhood but the concepts and values of family, home, religion, community, capitalism, and democracy. â⬠(De Simone) ââ¬Å"The Yellow Wallpaper,â⬠starts off with the main character, Jane, talking of a ââ¬Å"colonial mansion,â⬠that seems to be a place to vacation. Gilman gives detail of this set-back home that almost gives the reader an eerie feeling, which foreshadows events to come. When Jane starts to describe her husband, she gives the sense that he mocks her and he often laughs at her. This symbolization gives insight to her own life where she often felt mocked and taken for granted by men. As the story goes in deeper, Jane tells that she is going to the house because of the rest care she was prescribed, very similar to that of Gilmanââ¬â¢s. When they get to the house, Jane enables the reader to see the room with the yellow wallpaper. The windows were barred and there were restraints on the bed and she tells of scratches on the walls and ceilings. Jane believes that this room could have been a nursery or a babysitting room, but this does not make sense because when Jane reaches out to scratch the walls, she can barely even touch. How could a young child have ever reached if Jane, a grown woman, could not? As time goes on, Jane gradually learns to enjoy the room she is staying in, except for the dreaded yellow wallpaper. After being in the room for so long and dwelling on the wallpaper, Jane discovers someone trapped behind it. Jane believes she is getting better in health, but secretly is becoming obsessed with the woman, or so she believes, behind the wallpaper. Throughout the story, Gilman uses the romanticism approach. Romanticism expresses sensibility and passion. A romantic writer incorporates symbols, myths and images in their writing to help tell the story. Jane recognizes herself as the women trapped in the wallpaper. She believes that it symbolizes her feeling trapped in the house and under the control of her husband. She uses the Gilman tells of the room with barred windows and restraints as if it were a normalcy. Reading more into the story, the reader can gather that Gilman was symbolizing this room as a woman in a manââ¬â¢s world. The windows are barred, showing that there is no escape from that way, as there is no escaping a man in the universe. The restraints symbolize that a man can hold a woman back, along with keeping her close so that she doesnââ¬â¢t wander off. The idea of the woman creeping behind the paper mirrors Jane creeping to write, while being told that it is not recommended for her treatment. Although the ideas may be far out, the story that Gilman tells reflects her own life in many ways. When Gilman introduces the woman behind the wallpaper, itââ¬â¢s almost as if she is introducing herself into the story. Jane possesses many qualities and characteristics that Gilman portrayed in her own life and when Jane sees the woman in the wallpaper, itââ¬â¢s just like Gilmanââ¬â¢s conflict with her own mind. It symbolizes a womanââ¬â¢s want to break away from society and be her own person in this world that has a complete control over her. Whether itââ¬â¢s a father, husband, or even brother, this time period focused on maleââ¬â¢s first. The woman was told what to do and how to act and there was no room left for questions or disobedience. ââ¬Å"Life is very much more exciting now than it used to be. You see I have something more to expect, to look forward to, to watch. I really do eat better, and am more quiet than I was. John is so pleased to see me improve! He laughed a little the other day, and said I seemed to be flourishing in spite of my wall-paper. â⬠(Gilman 165) This quote displays Janeââ¬â¢s new obsession with the wallpaper and the thought that she is truly getting better. The fact that she mentions Johnââ¬â¢s happiness with her health leads the reader to think that he is a caring man, but after understanding Gilmanââ¬â¢s own life, makes the reader see him as the domineering husband that he is. ââ¬â¢Ive got out at last,ââ¬â¢ said I, ââ¬Ëin spite of you and Jane. And Ive pulled off most of the paper, so you cant put me back! ââ¬â¢ Now why should that man have fainted? But he did, and right across my path by the wall, so that I had to creep over him every time! â⬠This last quote is one of the most meaningful parts of the entire short story. While saying this, Jane makes herself become the woman in the wallpaper. Not only is it just a thought anymore, but when she lashes at her husband by saying ââ¬Å"you and Jane,â⬠Jane loses her sense of identity and takes on the role of the woman behind the wallpaper. She tells him that he cannot put her back, symbolizing that Jane does no longer want to be restrained to the room, nor him. Even after he faints, he is still in Janeââ¬â¢s way, leaving her to creep around him still. ââ¬Å"Even while considering herself a writer, and implying that she could have been a notable artist, throughout her life, Gilman qualified her artistic achievements by insisting that what she had done was ââ¬Ëperfect of its kind, but not art'; that she was devoted to ââ¬Ëliterature and lecturing,ââ¬â¢ but that her writing was ââ¬Ënot, in the artistic sense, literature. (Heilmann) Gilman was an impeccable example of what happens when a womanââ¬â¢s potential is seen over. She led a successful life and her work has helped the female race raise awareness of their capability in life. Although Gilman lived a long time ago, her work then has given females today a better understanding of where they have been, but also where they are going.

Lion King vs Hamlet Essay -- essays papers
Lion King vs Hamlet The movie, The Lion King, and the book, Hamlet, both have a similar story line. In both stories, the king is killed and revenge is sought by the kingââ¬â¢s son. The murderers in the stories are the kingââ¬â¢s brothers who want the power of the throne. After the death of the Kings, both of the villains successfully took over the kingdoms. While these villains ruled, the kingdoms slowly deteriorated. Neither of the sons liked the villains, but they did not know at first that they had anything to do with their fatherââ¬â¢s death. It took an outside force to convince them that they must vow revenge for their fatherââ¬â¢s death. Both sons had the wit to approach revenge strategically. They wanted the villains to know that they knew about how their fathers were murdered. The leading roles in each of the stories had a corresponding role in the other. The corresponding characters shared a number of similarities, but it was the ways in which they were different that determined their fate and that of the kingdom. In Hamlet, the prince is Hamlet. He is in deep grieving of his fatherââ¬â¢s death. He is angry because he believes that everyone has already forgotten how great of a king his father was. Hamlet does not know for sure who is responsible for his fatherââ¬â¢s death, but he suspects Claudius who is his uncle and the new king. Hamlet decides that if he can convince everyone that he is insane, then maybe he will be able to get someone to tell him more about his fatherââ¬â¢s murder. In The Lion King, Simba is the prince. Simbaââ¬â¢s father, Mufasa, is killed after he falls from a cliff into a herd of hyenas. Simba falls into a deep depression after his uncle Scar twists things around and convinces Simba that he is the one responsible for th e Mufasaââ¬â¢s death. Simba can not deal with what has happened and he runs away from the kingdom. In Hamlet, The new king Claudius is able to gain respect from the kingdom. He even steals the love of Hamletââ¬â¢s mother Gertrude. The old kingââ¬â¢s councilor, Polonius, becomes Claudiusââ¬â¢s councilor and his best friend. He helps Claudius keep an eye on Hamlet and tries to keep him from finding out anything about his fatherââ¬â¢s death. Polonius believes that if he helps Claudius that he can make life better for himself and for his daughter and son. But in the end, his actions get him slayed, drive his daughter to insanity, and eventually set... ...f her son. She starts to feel the poison and she warns Hamlet of it before she dies. It is too late though, the poisonous sword had cut Hamlet. In anger, Hamlet steals the poisoned sword and runs it into Laertes. He then charges Claudius and runs it into him. He also takes the wine and forces Claudius to drink from it. Both Claudius and Laertes die before Hamlet. Hamlet regains his throne for a few seconds, until the poison sets in and takes his life. The Lion King has a happy ending. Simba returns to his kingdom and he finds Scar. He tells Scar that he knows about his fatherââ¬â¢s death. Scar lies to Simba by telling him that the Hyenas were the ones who killed Mufasa. This upsets the Hyenas. They leave Scar to fight Simba by himself. Simba wins the fight and throws Scar off a cliff, into the herd of the Hyenas. The hyenas show no remorse for Scar and they trample over him, killing him. Once Simba takes back the throne, the whole kingdom becomes beautiful again and everyone i s happy. The two stories had similar plots and characters. But in the end, the small differences in how the characters acted separated the tragedy of Hamlet from the happy ending of Disneyââ¬â¢s The Lion King.

Materials For Torque And Aluminium Engineering Essay
Modern vehicles with constituents made of aluminum can be 24 % lighter than one with steel, which besides allows fuel ingestion to be reduced by 2 liters per 100 kilometers. Besides the above mentioned facts, aluminum is besides corrosion opposition ( Aluminium Leader 2011 ) . Engineering applications are germinating quickly, enabling new constituent designs, for burden bearing and fabrication systems. Modern stuffs include fibre complexs, proficient ceramics, technology polymers and high temperature metal metals ( Ashby et al. , 1985 ) . The vehicle interior decorator must be cognizant of these developments and be able to choose the right stuff for a given application, equilibrating belongingss with processing, utilizing a basic apprehension of the structural inter-relationships. Metallic elements and Alloies: Metallic elements are non copiously available, therefore, can merely be used for specializer applications such as catalytic convertors and powerful lasting magnets. However, metals such as Fe, Cu and aluminum, which are copiously available and can be easy extracted are widely used in both, pure every bit good as alloy signifier ( Cottrell, 1985 ) . At present, loosely used and cheapest stuffs are Iron-based or ferric metals. Mild or low C steel is adequately strong with output strengths changing between 220 and 300 MPa for low burden uses. Further, it is easy to cut, flex, machine and dyer's rocket. High output strength is required for drive shafts and gear wheels due to higher tonss. Therefore, medium C, high C or metal steels, ( yield strengths of 400 MPa ) are used for these intents. Higher strength and wear opposition are needed for bearing surfaces. For such parts, medium and high C steels, hardened by heat intervention and extinction ( increases the output strengths to about 1000 MPa ) , are used. Unfortunately, these hardened steels become brickle following this heat intervention, so that a farther mild re-heating, called annealing, is required. This reduces the crispness whilst keeping most of the strength and hardness. Stainless steel steels are alloys with a assortment of signifiers, viz. , Austenitic, Ferritic, Martensitic and the newer Duplex steels. A common composing contains: Chromium ââ¬â 18 % nickel ââ¬â 8 % ( BS 970, 1991 ) Their corrosion opposition and creep opposition is superior to kick C steels, peculiarly at high temperatures, nevertheless, higher stuff and fabrication costs limit their usage in vehicle technology to specialist applications such as longer life exhaust systems. Cast chainss have 2 to 4 % C, in contrast to the 1 % or less for other ferric metals mentioned supra. This makes them brittle, with hapless impact belongingss, unless heat-treated to bring forth malleable Fe. Since the higher C content reduces the thaw point, it makes pouring into complex shaped molds much easier, hence, it is more readily project than steel. The C in the signifier of black lead makes an ideal boundary lubricator, so that cylinders and Pistons have good wear features, for usage in Diesel engines. However, it is now mostly replaced by the much lighter aluminum alloys for these applications in gasoline engines. Copper is besides used in vehicle technology. It is more expensive than steel, but is malleable and can be easy shaped. Due to its high electrical conduction, it is used in wiring and telegraphing systems. Brass is a Cu metal, normally with 35 % Zn, which makes it easier to machine yet stronger than pure Cu. This helps bring forthing complex forms for electrical adjustments. However, such metals suffer from a long term job, known as & A ; acirc ; Ãâ ?dezincification & A ; acirc ; Ãâ â⠢ , in H2O. Corrosion can be minimized by utilizing the more expensive Cu metal, bronze, where Sn is the debasing component, although this stuff may be harder to machine. Copper-nickel metals have good weirdo opposition at high temperatures where they are besides corrosion resistant. The latter belongings is made usage of in brake fluid pipe-work. Aluminum and its metals have a major advantage over steels and Cu alloys, as vehicle technology stuffs. As mentioned above, their much lower densenesss lead to take down weight constituents and attendant fuel energy nest eggs. Whilst aluminum ores are abundant, the extraction of pure aluminum is really energy demanding, being electro-chemical in nature instead than the purely chemical procedure used for steels. Copper occupies an intermediate place on this point. Thus, pure aluminum is more expensive than Fe and Cu and has lower characteristic strength and stiffness. However, it does hold corrosion opposition with good thermal and electrical conduction. A broad scope of metals is now available with assorted heat interventions and fabricating chances. These stuffs have now replaced steels and Cu metals in many vehicle constituent applications, where their higher stuffs costs can be designed out, see Figure 4.1. However, stuffs developments are such that aluminum metals are themselves in competition with polymers and composite stuffs for such applications as vehicle body-work, see Figure 4.2. A composite stuff is a combination of two stuffs, with its ain typical belongingss. Its strength or other desirable quality is better or really different from either of its constituents working entirely. The chief attractive force of composite stuffs is that they are lighter, stiffer and stronger than most other structural stuffs. They were developed to run into the terrible demands of supersonic flight, infinite geographic expedition and deep H2O applications but are now used in general technology including automotive applications. Composite stuffs imitate nature. Wood is a complex of cellulose and lignin ; cellulose fibers are strong in tenseness but flexible and lignin Acts of the Apostless to cement the fibers together to make a stuff with stiffness. Man-made complexs achieve similar consequences by uniting strong fibers such as C or glass, in a softer matrix such as epoxy or polyester rosin. Considerable monetary value fluctuations in stuffs occur from clip to clip due to fuel monetary value fluctuations so that the cost values should be considered in comparative footings. The choice of a metal for a design application requires experimental informations. The first phase will find which group of metals should be used, steels, Cu or aluminum ( see Table 4.1 ) . Then a specific choice will necessitate more elaborate information. Testing of stuffs and constituents will hence be required. Some belongingss are mostly independent of composing, microstructure and processing. These include denseness, modulus, thermic enlargement and specific heat. However, many belongingss are really dependent on metal composing, microstructure, heat- intervention and mechanical history. These belongingss include output and tensile strength, ductileness, break stamina, weirdo and fatigue strength, so that specific information is required ( Smith, 1993 ) .
