Light Weight Material for Automobile Essay Example for Free

Light Weight Material for Automobile Essay General segment car with light weight alloys and metal matrix composites 1. 1 Analysis An automobile is a single biggest polluter, as emissions from millions of vehicles add up. As motor vehicles have been huge sources of pollution for the world since the last hundred years, the major car companies and market see profit by introducing some new technologies to reduce emission and delivering best solutions to customers. One of the major reasons for emission is weight of the vehicle. As weight increases carbon emission increases and fuel efficiency decreases. Both equally reduce customer perceptions. Present market battles to reduce carbon emissions and to fulfill customer demands for highly fuel efficient vehicles. As the above statement is top priority in present market and coming future, metallic parts of a general segment car will be replaced by light weight alloys by coming decades. However significant cost challenges are there for using light weight materials from manufacturing process to end life cycle. Smartly tackling of this cost will be the key to market applications. 1. 2Strategic sense which helps to make light weighting vehicles Global warming, global fuel prices and fuel demands are going to a critical situation, which makes human to think alternatively. As more fuel uses, more CO2 produces. If majority of vehicles made by steels are replaced by lightweight vehicles, it will reduce the global fuel needs. As this initiative makes very good advantages to world, it will get a lot of co-operation from other industries governments and political systems. Technologically and economically there are a lot of challenges and things to be done. Much RD works to do. Right from material selection, product design, process design, manufacturing methods, joining methods all has to be redesign for established organizations. It is a very big challenge. 1. 3 Initiatives taken to make light weighting vehicles To achieve a light weight structures, without compromising rigidity auto engineers have been researching the replacement of steel with plastics, aluminum and magnesium. Using of advanced material for reducing weight is the least expensive way to reduce energy consumption and carbon emissions. It is found that; * For every 10% weight reduction in weight of a car will result in 5% -7% improvements in fuel efficiency. * For every kilogram of weight reduction of a car will result in the reduction of carbon dioxide about 20kg. [1] 1. 4 Weight saving and relative cost for light weight material Figure 1. 1 Relative material properties and cost [2]. Important key factors while using advanced light weight materials are manufacturability, cost and joining processes. But as requirement is the mother of invention, manufacturability of aluminum and its composite’s will become easier and economical by coming years. Different manufacturing techniques are there to form aluminum into desired shape. 1. 5 Vehicle Case Study Super light Car Project: Figure 1. 2 Light weight materials, a vehicle case study [3] The objective of this project was to make an innovative idea by multi-material and light weight structure. This project proved that, BIW panel structure weight can reduce by 30%, multi material manufacturing with reduced cost, recyclability and sustainability of light weight materials. This project was a benchmark performance by joined venture of many sectors and seven vehicle manufactures (including Volkswagen and Volvo), 10 suppliers, 10 RD companies and seven universities. The final product was a mix of different materials and a wide range of joining technologies. The figure 1. 2 shows the benefits, that Super Light Project achieved.

Employee Rights and Discipline Essay

In the society, the concept of individual rights and personal freedom is viewed to be an important element and part of social structure and perspective. Social institution, organization and the legal opinion give high regard and importance towards this concept as inclined with the desire of promoting democratic opinion towards freedom and equality. Human civilization is founded with the values of independence wherein people enjoy personal freedom free from oppression and commanding power. Thus, the personal right for freedom is viewed to be an important element in the life of each individual as he or she exists in the society. However, the concept of individual right is often in contrast with the society’s pursuit for organized system within its structure. People desire to have a certain degree of control and power over its organization for the purpose of management for the attainment of their desired accomplishment and success. For the attainment of social discipline in the social organization, certain individual rights need to be limited for the purpose of management and control for the effective and efficient process of each social institution. For example, in the working environment, personal right for speech and opinion must be limited and restricted for the purpose of management of the said organization. This concept is indeed logical and permissible on this view however, the practice and application of the argument can likely cause critical and complicated questions. The troubling concern in this argument is the use of the power of restricting the right for free speech in the work environment. If implemented for the ideal reasoning and pursuit of social organization and discipline, limited the free speech is indeed permissible however, abusing this power through utilizing it as a mean of suppressing individual rights for personal benefit is already negative and detrimental. In addition, in the said scenario, limiting the free speech is permissible on some grounds however, there is still the need to develop a system where employees can still express their opinion, complain, and suggestion to the management on a way that will not negate or contradict their social discipline. The restriction on the individual right is only needed to achieve the ideal obedience and discipline in the work organization and environment necessary for the effective accomplishment of their tasks and processes for their success.

How Technology Has Changed Our Brain - 1452 Words

CC Orellana B3 The purpose of technology is not to confuse the brain but to serve it. A computers are machines that use a binary system to store, memorize, and manipulate information, just quite like the brain. A computer is able to carry out a series of logical operations, but yet so is our brain. The computer has memory that stores data and central processing unit that carries out certain steps, but yet so does the human brain. From the first computer just being used vacuum tubes, to use the silicon chips, there has been a technological revolution. Each year for the last ten years, technology has been becoming smaller and more capable of faster processing. Technology makes it possible for the use of countless labor-saving machines. This†¦show more content†¦So to look forward, the age group most researchers look at the people that are the ages between fourteen and twenty-four by 2014. Millennials have been showing growth and process throughout the time period many have been arguing about whether the new generation of digital technology i s making the young generation to become smarter, or stupider, than generations before. Recent psychologists and scientists are beginning to find their answers. They have found research on many of the current technological innovations that have helped benefit the millennial generation. One example of which is Auto-complete. Frequent users of phones, tablets, and laptops quickly get used to the auto-complete function of their devices, they need only type a few letters and the electronic device easily corrects and fills in the word. This handy function make just seem to make adolescent users faster, but surprisingly more accurate, when responding to a series of cognitive tests, according to research in 2009 from the journal Bioelectromagnetics, it was found that teenagers are actually learning better grammar, spelling, and diction. Another technological innovation is texting, as a study led by University of Coventry in Britain surveyed a group of teens about their texting habits, then asked them
