Virtual Reality - Research Paper Example These applications range from educational to health systems. However, the technology also has harbored some disadvantages due to its application. This paper delves into the topic of Virtual Reality. It examines some of its uses, its disadvantages as well as challenges that hinder its effective application. Introduction Virtual reality is a three-dimensional environment. One can only view it on a computer screen or through special goggles. Besides, one can relate with the virtual world as if one is part of it using specially designed equipment (Owens, 2010). According to Isdale (1993), virtual reality is a means for individuals to manipulate, interact and visualize with extremely complex data and computers. In this case, visualization part talks about the computer producing auditory, visual or other sensual outputs to a human being within the computer. This world could be a scientific simulation, a view into a database, or a CAD model. Conversely, the user can relate with the world an d directly and control objects within the world. In addition, other processes like simple animation scripts or physical simulations animate some worlds. With virtual reality, there is a likelihood of custom-designed while the three-dimensional environments permit instinctive â€Å"transparent† boundaries such that the computer interface is imperceptible to the user. In addition, virtual reality allows for considerably improved three-dimensional perception and interaction over conventional three-dimensional computer graphics because of its interaction capabilities and three-dimensional display (Bryson, 1996). On the other hand, VR can also be useful in an advanced user interface to three-dimensional simulation models in simulation terms (Barnes, 1996). Moreover, there are various fields in which VR applications have significant potential including medicine, industry, education and training, commerce, entertainment industry, scientific research and the space. On the other hand, to make innovations that use VR technology effective, there should be a thorough exploration. However, VR is still immature both as a technology and as a field of research. As a result, there should be considerable research to be done to realize the full potential of VR (Barrett, 2004). This is the reason the electronic and computer engineers are pursuing new ways of improving the virtual reality experience. Presently, computer and electronic scientists and engineers are developing a system that will incorporate the sense of taste (Lee, 2011). Applications and equipment for Virtual Reality Several technologies are requisite for the creation of a virtual world each of which, have advanced technologically and independently. The heart of virtual reality is a combination of software, hardware and electronics. These three computers related technologies merge to make virtual reality work. In addition, three imperatives are essential to help virtual reality work including special software , the individual user and a computer. Moreover, there are several input devices to improve the virtual reality experience and enable it to work. These input devices help in recording, measuring electronic signals, and converting them into a physical world. On the other hand, the output devices allow the user's brain to process the computer-generated physical world created. However, the reality engine is the main power of a virtual reality system. This engine helps create the virtual world and process information. It comprises either a group of computers or one powerful computer because the reality engine is supposed to create complex graphics (Lee, 2011). However, the virtual reali

American Foreign Policy Essay Example | Topics and Well Written Essays - 750 words

American Foreign Policy - Essay Example This form of power is often employed by a country having more economic and military power over its subject. This form of power is usually achieved by use of rewards such as economic inducements, promises of military support and alliances or through threats of punishment such as economic sanctions, coercive diplomacy and military interventions. The article ‘The Practice of Foreign Policy† clearly illustrates the concept of hard power adopted by the U.S. government over the past few years. The article brings to light the growing number of countries that have at one time or another experienced intrusion or use of hard power by the U.S. government. It highlights the growing discontent among countries such as Syria over president Obama’s wayward policies. In addition, the article analyses America’s stance towards war and use of diplomacy (â€Å"The Practice of Foreign Policy† 1). The U.S has been accused of spying Brazil and other countries, which basicall y is a form of hard power. The armed forces are described as â€Å"peerless†, illustrating hard power. In Syria, the U.S. government considered the possibility of a military assault following the use of chemical weapons by the Syrian president. However, this move was voted down by the Congress. This illustrates use of hard power. The U.S. ... government has specific interest in oil, Islamic terrorism, Israel and Iran. The U.S. government has placed a number of sanctions on Iran over its nuclear power program. This illustrates hard power (â€Å"The Practice of Foreign Policy† 2). Soft power as earlier described is a situation whereby a country uses persuasive tactics such as co-opting with other countries in order to influence their interests or behavior. Soft power is becoming more and more common in the world today. The article suggests that through developing good strategies and implementing them, the Obama administration can restore confidence and win back people. Soft power can also be enhanced by use of diplomacy. The number of diplomats ought to be increased as well as taking interest in their recommendations (â€Å"The Practice of Foreign Policy† 2). The article â€Å"Making up; Soft Power† illustrates use of hard power. The U.S. invasion of Iraq in the fight against al-Qaeda has been termed as use of hard power. The U.S. government used raw power in an effort to crush the outlawed group. The America’s interest was to fight terrorism. The U.S government has been criticized on many occasions for meddling with the Middle East, yet, it does so little to solve underlying problems. In Libya, the U.S. government exercised hard power by ousting the then president Muammar Qaddaffi from power. The U.S. has interest in humanitarian welfare following Muammar’s threats to kill innocent civilians. The article also raises concerns over the U.S. government’s widespread spying by the NSA. Spying illustrates use of hard power. In 2003, the U.S, invaded Iraq. Its interest was twofold; arresting proliferation of weapons of mass destruction and show of power or might (â€Å"Making up; Soft Power† 1). The

Islamic ceramics Essay Example | Topics and Well Written Essays - 1500 words

Islamic ceramics - Essay Example This is in part has been attributed to the influence of science and technology in ceramics and pottery traditions which coincided with the scientific renaissance of the 10th and 11th centuries (Fehervari, 2000). The innovation of the period mark not only the development of the craft but give insights to how cultural and scientific development impact society together. Islamic ceramics and pottery have been traced to the 8th century, developing in key Middle Eastern civilization centers such as Iraq, Persia and Syria. Excavation indicated that most artifacts from the period were mainly utilitarian and had only used basic glazing methods. However, by the late 8th and the early 9th century, the glazing became a common practice and there was significantly increase in artistic competencies which included the introduction of lusterware production. Excavations in Basra, Damascus and Fustat show intricate ceramic painted walls using blue as a predominant color, a traditional that will eventually be a characteristic of Islamic ceramics and pottery. According to Lane (1947), the Abbasid dynasty, early supporters of Mohammed and Islam, utilized ceramics and pottery as a means to promote their political power as well as the religion, which became the foundation of the concept of an â€Å"Islamic† tradition of pottery. The period also provides documentation on the trade with China which is major influence to artisans. Aside from trade, there was also an exchange in technology and styles which reached a high during the Seljuk dynasty with the arrival of the Mongol invasion but which subsequently declined with the decline of the Mongol Empire. This level of interaction would only be augmented once more in the 15th century peaking during the Tang dynasty (Meri & Bacharach, 2005; Fehervari, 2000). One of the key features of Islamic ceramics and pottery is in the use of glazes which allowed artisans to create an opaque, metallic-like finish to

Hence, owing to this aspect, the statement or the assumption of Carr can be contradicted up to a larger extent. Table of Contents Abstract 2 Introduction 4 Company’s Profile in the Industry 5 Competitive Environment of the Global Retail Industry (Porter Five Forces Analysis) 6 Bargaining Power of the Buyers 7 Bargaining Power of the Suppliers 7 Threat of New Entrants 7 Thereat of Substitutes 8 Intensity of Rivalry 8 Role of Information System in Tesco PLC 9 Analysis and Conclusion 11 Analysis 11 Conclusion 13 References 15 Introduction In today’s business scenario, the success and failure of any sort of business depends mainly upon various deciding factors that impose considerable influence on the operations. These factors may be related to customers’ perceptions and their level of satisfaction among others. These ar e often regarded as major determinants of the overall organisational success. In this regard, the role of information technology (IT) has become quite crucial, acting as a major element in enhancing the operational efficiency of the business. ... It is one of those elements, which is extensively available and any company can adopt the same. Hence, it cannot be regard as a tool to gain competitive advantage. To analyse this statement of Carr in an in-depth manner, this paper will evaluate the role of IT in organisations with the help of taking an organisation named Tesco as an example. Accordingly, the statement of Carr can be contradicted or supported on the basis of the analysis made over the organisation. Company’s Profile in the Industry As per the discussion of Nicholas Carr, the presence of information technology (IT) in business does not make any difference in the overall performance of the business. According to Carr, this is owing to the fact that IT is easily accessible for each and every company in their operation and hence it cannot be implemented as a tool for gaining competitive advantage. In order to get a comprehensive understanding in this regard and analysing the statement of Carr, considering the exam ple of Tesco will be quite vital. Tesco is regarded as one of the leading grocery and merchandise retailers throughout the world, which has its operational headquarter in the United Kingdom. In terms of profit earning, the company is regarded as the second largest operator of the world next to Wal-Mart. It has widespread operations throughout the world and it performs various operational functions in a large scale. In the present day context, the company possess greater percentage of market share in the global retail industry. The large scale operations of the company can be apparently depicted from the fact that it currently employs more than 530,000 people all over the world. Observably, one of the major reasons for the

Problem Solution Paper Essay After assessing my LASSI test scores, I’ve learned that I need some improvement in my study habits. To name a few, some of my strengths are concentration, motivation, and selecting main ideas, however, my weak areas such as information processing, study aids, and time management all were right on target. I’ve always had problems with studying something that I did not understand, therefore it would frustrate me and I would not spend much time on it. I am currently struggling with this problem in my English 111 class because it is hard to process what I am reading in the textbook. In addition to that I am a full time general manager at a restaurant and it is very demanding, working long hours and then trying to come home and study, I am forced to cram my school work in on my off days because I am very tired. I really feel that if I do not come up with better time management skills and stop cramming my work that my short-term problem academically will be that I turn in below average assignments or not even meet deadlines. My long-term problem will be that I fail my class and lose my financial aid, so I will definitely put more effort into a solution. My problem is time-management and the three solutions that I have researched and think would be a good fit for me are 1. Blocks of study times and breaks. [www.studygs.net/timman.htm-time management] The advantage of this solution is that I would have time set aside to study with the option to take a break so I want get to tired. The disadvantage of this is I might take a break and never come back to it because of other distractions such as tv, cellphone, fatigue, etc. Secondly, review planner weekly. [www.studygs.net/timman.htm-time management] I would be able to review planner and know when test and deadlines are do for papers. The disadvantage would be, if I’m not consistent with logging things in the planner I could forget about something. Lastly, the third solution would be to stay healthy, schedule rest.  The advantage of this would be that I would be well rested and rejuvenated to tackle my scheduled task, and disadvantage would be that I get home at 5pm sometimes and if I take a nap I will not be able to recover from that. I feel that the best solution would be to set aside time to study and take breaks if needed and I will use this strategy with my English 111 class.

Australian Paper Manufacturers Essay Example for Free

Australian Paper Manufacturers Essay Introduction The case deals with the Australian Paper industry in 1990, the major players operating in it and how the environment is throwing up challenges to its major players and shaping the future growth of the industry. The paper industry in Australia can be separated into three categories Newsprint, Paperboards and Fine paper. The industry is dominated by two big players namely the PCA and Australian Paper Manufacturer (APM) and the rest catered to by imports. PCA operates in the fine paper market enjoying a 75% market share, while APM is a leading player in the paperboards segment. Both the companies are part of a huge diversified parent organization. Environment regulations from the government, green peace activists have been recently posing threats to PCA on organochloride emissions. APM is proactively seeking to strive ahead of the environmental issues facing the industry. Ken McRae, the GM of APM has to decide on three alternatives to choose upon for utilizing the A$ 50 million allocated by the parent company Amcor, keeping in view the Financial, Strategic, Ethical and Environmental issues. Case Facts Before 1987, the Australian paper industry was divided into three companies. Australian Newsprint Mills supplied newsprint, Australian Paper Manufacturers produced paperboard, and Paper Company of Australia produced coated and uncoated fine-papers. All three of those companies were subsidiaries of major Australian corporations. Maitland sales, which owned Paper Company of Australia (PCA), recorded $495 million in net sales. Amcor Limited, which owned Australian Paper Manufacturers (APM), grossed $2.4 billion in net sales. APM decided to enter another aspect of the paper industry and dive into uncoated fine papers. They figured that they could draw on their strength in paperboard manufacturing. The making of fine paper or paper in general requires close attention to detail. The first step in making paper requires the wood to be pulped. This process refined the wood so that only the fibers remained. During pulping, the cellulose fibers were separated from the other components so it could be processed further. This process can be done in two different ways, mechanically or chemically. The chemical process produces much sturdier pulp, but unlike mechanical pulping, which uses 90-95% of the wood, chemical pulping uses 45-50%. Chemical pulping is also the least environmentally friendly of the two. When the fibers are made into fine paper, it goes through an immediate step called bleaching, where as chlorine gas and chlorine dioxide are applied to the pulp. After bleaching, chemicals such as, rosin, aluminium sulphate, or synthetics to reduce absorbency for writing papers. The annual consumption of fine paper in Australia rose to nearly 358,000 tonnes in 1987. Uncoated fine paper, such as photocopy paper, stationary, and offset printing paper, comprised 52% of that market, while coated fine paper, the type used in an annual report, comprised of the rest. In 1984 APM completed a a $163 million modernization of its kraft pulp plant in Maryvale, Victoria. The improvement added 140000 tonnes per year of kraft pulp capacity, bringing the Maryvale plant’s total output to 350000 tonnes per year. The Maryvale plant had four paper machines and in 1986 APM turned its attention to Paper Machine 3.Originally built in 1972 to produce brown shopping bags Machine 3 had a capacity of 31,000 tonnes per year. By the mid 1980s, though people had stopped using these checkout bags and between Machines 1 and 2 the company could cover demand. This left Machine 3 ripe for transformation. APM seized the opportunity, upgraded machine 3 and used it to take them into the heart of PCAs fine-papers market. People in the plant were convinced that it could be done and that their years of experience in making bag paper could be adapted to such a closely allied process. A number of trial runs were made in order to determine the general viability of the idea. Once it was proven feasible, APM sanctioned the investment. Between May 1986 and July 1987 APM spent A$50 million to rebuild Maryvale’s Machine 3, converting it from making bag paper to producing white wood free paper. The upgrading of Machine 3 had not only put APM next to PCA as the second domestic supplier of uncoated fine paper. It also made APM the owner of Australia’s largest and most technologically advanced fine paper machine. The 70,000 tonnes per year of Machine 3 capacity gave APM the product it needed to steal from imports-the company’s primary goal in entering the fine paper market. Customers had been accustomed to buying some of their paper from PCA and some from overseas but PCA had not kept pace with the growth in demand. Although aiming to replace imports, McRae, director marketing for APM papers group at the time, knew his toughest job lay in establishing APM’s fine papers amid a market dominated by PCA. In August 1987, APM inaugurated its move into the fine papers market. McRae developed a careful paln for ramping up to full capacity on Maryvale 3.APM intended to be producing at 40,000 tonnes annual rate by august 1988, starting with three crews working Monday through Friday and eventually moving to four and then five crews. Like all of Maryvale’s other paper machines, Machine 3 would eventually operate 24 hours a day, 365 days a year. By August 1988, Maryvale Machine 3 was producing at a rate of 50,000 tonnes per year and by March 1989 it had reached its capacity of 70,000 tonnes per year. In May 1989 APM introduced its newest entry in the fine papers market, ReRight. It was Australia’s first stationery paper made from 100% recycled paper- post- recycled paper that was produced without chemicals and was neither de-inked nor bleached. The World Wildlife endorsed ReRight and the product generated significant interest and publicity. Despite ReRight’s higher cost it grabbed a 3% market share (7,000 tonnes per year) of the uncoated fine papers market. To recoup its research and development expense, APM charged 20% more for ReRight than for comparable, non recycled paper. ReRight’s immediate acceptance inspired APM to introduce ReRight-Form in the spring of 1990, a recycled computer paper. While APM expanded its recycling efforts PCA suffered yet another blow on the environmental front. Greenpeace released a surprise report on PCA’s Kayser soda pulp mill on the coast of Tasmania, declaring it the dirtiest mill of its type in Australia. It found Kayser discharging 11.5 tonnes of organochlorides per day into the sea, at times reaching a level 80% above government standards. It also decried the presence of chloroform a cancer causing agent, in the effluent and cited it as a health risk to PCA’s workers. The environmental group called upon the government to monitor the mill’s effluent levels more closely and demanded that the company reduce its discharge of organochlorines to a maximum of one kilogram per tonne of pulp. It also recommended complete elimination of organochlorine discharges by 1993 and asked the government to review employees’ medical records to search for abnormal incidence of cancers attributable to oraganochlorines such as chloroform. Future Scenario Encouraged by APM’s success Amcor had provided A$50 million to APM to consolidate yhe investment that had carried it into fine papers, though a pre-tax return of at least 20% was expected. While larger sums could always be requested, it was understood that larger sums required more attractive returns-as had been the case when APM originally entered the market by upgrading Machine 3. Further expansion into fine papers loomed as a possibility. Copier paper alone promised 10% annual growth and recycled paper continued to grow in popularity. The uncoated fine papers market as whole was projected to grow at a rate of 6.5% annually through the year 2000. Now, McRae had the following options for the capital budget: 1) The capacity of Machine 3 at Maryvale could be expanded upto 100,000 tonnes. Initial estimates put the cost of increasing from the existing capacity of 70,000 tonnes at A$35 million. McRae would have to decide how he would use this extra capacity. Analysis of option 1- 2) APM was producing 7,000 tonnes of recycled paper at its Fairfield plant and increasing capacity would cost A$18 million. Analysis of option 2- 3) In addition to APM’s recycling efforts, McRae focused on ways to reduce APM’s discharge of organochlorines. APM could reduce its dependence on chlorine by substituting oxygen in one of two ways: a) To replace chlorine through oxygen pre-bleaching, APM would have to spend A$15 million in development and implantation. Oxygen pre-bleaching would reduce chlorine use by 50%. Pulp output at Maryvale would drop by 5% from 350,000 tonnes to 332,500 tonnes, but many engineers at the plant had expressed keen interest in learning about the technology. Pulp contribution at Maryvale was A$200 per tonne of pulp. Analysis of option (a)- b) Alternatively, APM could intensify the use of oxygen during bleaching, which would reduce the level of chlorine by 15% and cost approximately A$8 million. Pulp output would be unaffected. Analysis of option (b)-
