How Fiber Optics Work essays

How Fiber Optics Work essays Thesis: In a fiber optic tube, the speed of light reflects from the cladding no matter what angle the fiber itself gets bent, even a full circle. Furthermore, because the cladding does not absorb any light from the core, the light waves can travel great distances. 3. Where was Fiber Optics discovered H. Transmitting Light through Fiber Optic Cables Our current age of technology is the result of many brilliant inventions and discoveries, but it is our ability to transmit information, and the media we use to do it, that is perhaps most responsible for its evolution. Progressing from the copper wire of a century ago to todays fiber optic cable, our increasing ability to transmit more information, more quickly and over longer distances has expanded the boundaries of our technological development in all areas. Fiber optic technologies are based on the same concept as the signal fires used in ancient China. Instead of sending the signals through the open air, however, a laser sends pulses of light to their destination through a thin strand of transparent glass. At the receiving end, an optical sensor decodes the light pulses with a complex set of standard codes. In some ways, it's also similar to the way people decode the dots and dashes of Morse code. In a fiber optic tube, the speed of light reflects from the cladding no mat ter what angle the fiber itself gets bent, even a full circle. Furthermore, because the cladding does not absorb any light from the core, the light waves can travel great distances. Craig C. Freudenrich, Ph.d defines fiber optics (optical fibers) as long, thin strands of very pure glass about the diameter of a human hair. They are arranged in bundles called optical cables and used to transmit light signals over long distances (par 2). Scientists at Corning Glass Works & Bell Telephone Labs, in the early 1970's, made the significant breakthroughs in optical fiber, to make it realistic to use...

Ethics of human cloning essays

Ethics of human cloning essays On February 23, 1997, news traveled around the world that scientists in Scotland had successfully cloned an adult sheep. What had previously seemed impossible, even to many scientists, was suddenly a reality. The sheep, named Dolly, had only one biological parent and possessed a genetic code identical to that of her original parent. Within days, the publics amazement over this development turned to questions of whether the technology that had produced Dolly could also be used to clone human beings. President Bill Clinton declared a moratorium on federal funding for human cloning research and appointed a commission to review the legal and ethical issues associated with the cloning of humans. More than three years later, there is still uncertainty about whether it will ever be possible to safely clone human beings. The scientists who cloned Dolly succeeded only once in a project involving the creation of 278 sheep embryos. The possibility of deformities and health risks in human children, as well as overwhelming public opposition to unrestricted cloning research, has led some U.S. lawmakers to call for a ban on human cloning, although no federal legislation has yet been passed. Medical and technical considerations are certainly not the only concerns surrounding the possibility of human cloning. The most contentious and difficult questions associated with human cloning are moral and religious in nature. Any discovery that touches upon the human creation is not simply a matter of scientific inquiry, President Clinton said in an Oval Office ceremony. It is a matter of morality and spirituality as well. In a recent poll presented by the Pew Forum on Religion and Public Life and the Pew Research Center for the People unrestricted scientific research related to human cloning and respondents most ofte ...

RB

RB Alborz Zinabadi Mr. Richard Urias American Literature December 15, 2000 Rhythm and Blues There are many types of music in the world but the one that stands out in everyone's mind is the sound of Rhythm and Blues. It has been around for many decades. It has captured people's interest around the world. Rhythm and Blues(RB), or as it was called before "black music", started in the early 1940's by slaves in the south. This phenomenon brought about new music, fashion, and dance styles.The white people thought of RB as black music during the 1940's and early 50's. It has the single greatest influence on music worldwide for most of the 20th century. Its influence can be traced in forms of rock music, country, gospel, jazz even Nigerian Juju -a style of dance music. Rhythm and Blues was started in the South, but later on moved to Midwest, Northeast, and West Coast cities due to the shift in American demographics, after World War II.The Rhythm and the BluesOne of two significant developments, which occurred that had an effect on RB was the invention of the Magnetic Tape, the other was the formation of broadcasting companies. (Schneider 40) The invention of the magnetic tape was a tremendous help to those who wanted to start their own independent record companies. Since no major record companies would accept music that was produced by black people, their formation of these independent record companies was crucial to RB recording. Most white radio stations did not play "black music", and when they did start playing RB, they were not obligated to play it. After noticing that the youth was more into RB they played it since they wanted to keep their young audience. In addition, the invention of the electric guitar had a tremendous effect on...

Knowledge Management Techniques - Essay Example Uriarte, 2008). The parking and preservation of corporate knowledge is relevant especially in today’s era, given that majority of work force oriented service is solely composed of knowledge workers. To successfully compete in the economy, companies have to treat the personnel providing the knowledge just as they would pay attention to any other strategic irreplaceable asset (Leistner, 2010). At high levels of the hierarchy of knowledge worker, certificates and university degrees from guilds or various organisations provide the self imposed labels that professionals and managers use in order to qualify for one of the positions in the organisation (Miltiadis et al, 2008). Knowledge workers have an overall picture of the business as oppose to the lower level front line workers, but there is the likeliness duplication of mistakes in the various departments since there is no strategy or media for information sharing example in an organisation professionals in various departments ma y be doing some experiments with out sourcing, independently each discovering that saving promised is far much less that suggested in the popular business press. Knowledge management is fundamentally about a systematic approach to other information and managing intellectual assets in a way that the company is provided with an edge to competitive advantage. Knowledge management is an optimisation strategy for business, and it is not limited to a particular source of information or technology (Uden and Eardley, 2010). A wide variety of IT (Information Technologies) plays a key role in knowledge management initiatives, simply because of the effort provided over manual operations and savings in time. Knowledge management is agnostic when it comes to source and type of information, ranging from a document describing the process a customer support representative uses to escalate

Globalisation , the World Economy and MNE's mini essay

Globalisation , the World Economy and MNE's mini - Essay Example However, a host country needs to have a minimum absorptive capacity and the ability to link these investments with domestic enterprises (Ruane & Gorg, 1998). FDI policies affect both potential and existing foreign investments either directly or indirectly. The host country justifiably sets its policies based on information, business failure, and intervention (Lall, 2000; Moran, 1998). Some of the policies include: A government should efficiently analyse and evaluate international firms before they invest in the country. Screening aids in identifying the purpose of the firm and the validity of its actions. Secondly, in ownership restraints, the host state decides to exclude foreign investors from certain parts of the economy (Hill, 2011). Exclusion based on the grounds of healthy competition and national security. For example, India implemented certain foreign ownership policies, which governed the retail sector since foreign traders almost put local supermarkets out of business (Mukherjee, 2005). Finally, performance requirements enable a country to optimize FDI benefits and minimize on the costs employed to the host country. Operational policies assist in controlling the activities of foreign companies in the host country. Governments implement operational activities through site restrictions, export requirements and persistence on partial ‘local content.’ Based on location policies, the state needs foreign investors to lay foundation in regions where they provide labour market. Secondly, based on the industrial activities, firms should locate to regions where they will not disrupt other forms of infrastructure or cause harm to the inhabitants. Export policies aim at managing foreign company exports mainly to create a balance between it and the domestic export (Moran, 2005). States implement export regulations through taxation policies. It also permits the exportation of only a set

Latin Western European Business Culture Essay Example | Topics and Well Written Essays - 2000 words

Latin Western European Business Culture - Essay Example Collectivism, the propensity of people to stay within a long-term group, is also rated high. The Masculinity rating corresponds to emphasis laid on the traditional viewpoint of men's and women's roles, while Uncertainty avoidance rating indicates that rules and long-term employment within the same structure are preferred. Finally, the long term / short-term rating is in favour of longer term attitudes, based on perseverance and relationships ordered by status. These cultural dimensions give a basis from which to assess certain aspects of Latin Western European Business Culture. However it is not the complete picture. In the areas of business communication, particularly in face-to-face communication and business negotiations, it is also of interest to compare the concepts advanced by Hall (Hall) and in particular that of the high context and low context cultures. According to Hall, in a high context business culture, the information transmitted in a communication is minimised because implicitly much of the information required is already present in the setting. Low context cultures are the reverse: the communication contains far more information because this information is not present in the setting. According to this model, Latin culture is high-context. Besides the situations already mentioned, this model also finds particular application in the advertising and promotional activities that most businesses engage in. This kind of communica tion remains somewhat basic and even terse in Latin countries as compared to the other Western European groups (Anglo, Germanic and Nordic). Hall also elaborated a second theory of how different cultures structure their time, which he refers to as polychronic or monochronic time orientation. A top-level approach for Latin countries puts them into the polychronic category. The immediate implications are of the priority of interpersonal relations over schedule and appointments, the simultaneity of tasks and the mixing of work time and personal time. Like the other theories alluded to above, this generates different results when we consider the four countries on an individual basis. Because the creation of the European Community has encouraged the individual member countries to trade more among themselves and, by extension, with the rest of the world, it is interesting to note how the Latin Western European countries and their businesses fare in a cross-cultural context. In particular, a different principle is applied here, that of the Self Referencing Criteria or SRC defined by Lee (Lee). In essence, this describes the cultural trap of assuming that other countries use the same cultural values as one's own. It is the failure to perceive things from the standpoint of a person of a different culture. The Latin countries that we are dealing with here display marked differences in this regard. The first country to be examined using these tools of cultural investigation is France. It is a country which at the same time is Mediterranean and Latin, but which also exhibits a number of non-Latin characteristics, in keeping with its proximity to, or common borders with, a number of (mainly) Germanic countries such as Germany, Belgium and Switzerland. Of the five cultural dimensions, French business culture can be classified as follows. Power-distance is relatively high with top
