Present And Future Of Electrical Engineering

Present And Future Of Electrical Engineering ABSTRACT The report is all about the past, present and the prediction of the future of electrical engineering in the branch of electronics which plays an important role in the improvement of electronic devices as well as the new technology, electronic engineering is a broad and challenging discipline because it is composed of different kinds of electrical components such as electron tube, transistors, integrated circuits etc, therefore from all these electronic components the most vital components are transistors as they have amazing characteristics compared to other components, transistor sizing is the most challenging when electronic engineers start to design thing like computers, electronic machine etc. Basically transistors make electronics engineering to become more efficient when it comes to the production of electrical appliances because from the past until nowadays, the usage of transistors had been increasing rapidly which shows that electronic engineers always makes life become easi er. 1. INTRODUCTION Electronic engineering in the past was not interesting because during that time it was hard to invert electronic material because there was scarcity of resources that was taking control over humans life. Electronics today is taking a lead because the economy and society benefits from electronic engineering, as this is seen by anyone living on this planet. Many companies use electrical appliances such as computers, laptops, telephones etc. which lead to a good profit to their companies and thus this result in a huge growth of the economy worldwide. Electronic components are more easily to be improved and this predicts that in the future things like plasma, laptops, internet are going to disappear because the electronics creates new technological devices every second and the way electronic engineering functions create hope of amazing changes that people might not believe because things such as Identity documents for the next years will be regarded as useless papers. The society also be nefits from electronic engineering because nowadays many health services uses electronics for example such X-rays and other electronics devices to detect for other diseases. Professional electronic engineers have good ethics because they also create strong educational activities by creating fair regulations that must be followed strictly to ensure that protection is sustained towards peoples life. 2. ELECTRONIC ENGINEERING CHARACTERITICS Electronic engineering is a branch of electrical engineering that deals with the implementation of applications, principles and algorithms by using non linear and active electrical components such as transistors, diodes and integrated circuits to produce electronic machines, televisions etc which is more related to other field, for example radio engineering, telecommunication, control system and many other [1, 2].The transistors are the best electronic components that has become more useful after they had been inverted and transistors have different function because of their size. They have different physical characteristics. 2.1. Design and application of transistors in circuits Transistors may have N-P-N or P-N-P structure which function as a switch both N-P-N transistors and P-N-P transistors consists of three regions: collector, base and emitter. The base is the transistors main lead, without it, the transistor wont function, the collector is the positive lead and the emitter is the negative lead. Therefore the N-P-N and other transistors are may be used to control the flow of electrical current, power flow through the transistors from the power supply to the relay controlling the flow of electricity. Sometimes NPN transistors may usually work as amplifiers by controlling large amount of current [3]. Figure is on the appendix. 2.2. Electronic components There are many electronics that are widely used in electronic engineering to invert special electrical appliances. Symbols of some electronic components are represented on the appendix. 3. BACKGROUND OF ELECTRONIC ENGINEERING 3.1. The past of electronics Electronic engineering has evolve from technological improvements in the telegraph industry long time ago in the late 19th century , Transistor is a well-known electronic component that is inverted in 1948 at the Bell Telephone Laboratories followed by integrated circuits in 1960, electronics is often considerable to have started when Lee De Forest inverted the first vacuum tube in 1907 within 10 years, all of his electronic device was found in radio, transmission and receivers as well as system for long distances telephone cells [1, 2],electronic engineering was interesting because many things that are inverted during the 19th century are now improved to produce better materials that are very useful. Electronics play a significant role when it comes to telecommunications because the beginning of electronics is more likely based on communication and it is also improving because after the invention of radio, telegraphy and other past electronics appliances the first purely electronic television is inverted in 1928 by Philo Farnsworth [2], therefore this trend shows accurately that electronics always strive to progress from generation to another. During 1930s television had become more popular because it was recognized by millions of people to the best thing that was transferring information easily. During the past the computers that was inverted they were not programmed like the one that are being used now because they were very big and it hard to find because they only found at the laboratory of High institution and these computers was using big transistors that was storing less resources, therefore the most benefit from early computers is that they were better in terms of information transmission when compared to televisions. During the First World War electronic applications had tried to play a vital role by creating electronic weapons for defence but the most successful electronics weapons are the one that was produced when Second World War take place[5]. Hence electronics had created a wonderful social awareness by providing people with strong electronic weapons to protect their life against their enemies. 3.2. The present of electronics Electronic engineering nowadays is a challenging field because there is a lot of competency for producing desirable electrical appliances which benefit the whole world. Electronic engineering is the best because many things that are being used all over the world to create peace, economic growth, excitement and employments are produced by electronic engineers. Information technology today is based on electronics because information is transferred from one place to another by using electronic materials such as cell phones, digital computers, advanced television such as plasma and other useful electrical appliances, therefore all of this benefit the country because it maintain peoples rights. Electronics is more useful for health services and educational purpose because today at universities they are using computers, power point during the lecture time and this help students to adapt, gain knowledge and skills in the electronic and technological environment. People all over the world ar e getting proper health care because there is variety of electronic applications on medicine e.g. X-rays, Ultrasound detectors, medical research and expands other diagnostic test which save human lives. Since the invention of radio television in the past other previous century the electronics industry has been increasing drastically with the beginning of computer technologies and cell phones the electronics industry is regarded as the world largest and fastest growing manufacturing industry. Therefore this flowing of electronics it release hazardous material that affect the environment because when electric product become cheaper they tend to rapidly become more useless and some of these materials are dumped everywhere which lead to pollution [6]. 4. THE PREDICTION OF THE FUTURE OF ELECTRONIC ENGINEERING Electronic engineering will always proceed to develop amazing things because educational level of electronics is improving each year which means that the economy will succeed more toward the following years because many people who are studying will invert new things that can become more useful than the present electronics devices. Technology is also faced with a huge change because electronic engineers are always trying to improve their skills. Cars the next following years they might use electronic components and electricity to move because petrol and other oils are regarded as dangerous pollutant on the environment. Electronic engineering it might be bad when it comes to domestic employment because the many things that are created by electrical engineers makes life easier to a specific person even other professionals might lose their jobs because the engineers work it shows accurately that one day an electronic doctor can be inverted to save doctors from their work because other di sease might infect during the working times. Therefore any person must try to be preparing for the next electronic generation because new desirable things are coming such as cell phones that can be used to drive cars. Laptops will be replaced by electronic engineers because they are big when compared to cell phones. 4.1. THE TREND OF ELETRONIC ENGINEERING The diagrams representing the trend of electronic engineering 5. CONCLUSION Electronic engineering in the past was poor but it has evolved rapidly. Nowadays people are used to electronic systems, therefore this shows accurately that electrical engineering as whole it will dominate toward the next four years because without electrical engineers lot of things will disappear like a mist for example the economy depends on electronics to fulfil its profit which means that when electronics drop the whole process all over the world will subside resulting in lack of employment, poor health care and other technological system will disappear. Electronics for the next twenty years it might program people to function as electronics because the introduction has already began by computers e.g. people are using computers to improve their thinking capacity and to get lot of information. Really electronics is the best thing that symbolise peoples intelligence because amazing things are taking place because of electronics e.g. the night is changed by lights which symbolise th at everything it might be created by electronic devices. 6.

Iago as the Hero of Shakespeares Othello :: GCSE English Literature Coursework

Iago as the Hero of Othello Roderigo, a soldier in Othello's army, is in love with Desdemona and is deceived by Iago into thinking that Desdemona holds some affection for him. Iago, who is Othello's "ancient" or his counselor, desires to hold Othello's position and so tries to devise a plan to become general. As proved by the outcome of the play, Othello was too naive and kindhearted to properly lead an army. Iago felt that he should have been promoted to be Othello's lieutenant but Cassio was promoted instead. The outcome of the play also proves that Iago was more efficient in achieving his goals. Iago's plan is one that involves Cassio, Othello's second in command, Roderigo and Desdemona. Iago is better qualified than either Cassio or Othello if he devised such a plan without either of them noticing. The same strategies he uses in everyday life he would be able to employ in battles. Iago has proven to be the ultimate soldier. Iago instills jealousy in both Roderigo and Othello by leading each of them to think that Desdemona and Cassio are having an affair. He accomplishes all this without being discovered until the end. During the course of the play, Othello is further deceived by Iago to believe that Desdemona is unfaithful to him. Emilia, Iago's wife, unknowingly helps Iago fool Othello when she gives her husband the handkerchief that was given to Desdemona by Othello on their wedding night. Desdemona always keeps this by her side, as a result of Othello's command. When Iago tells Othello that he has seen Cassio with his gift to Desdemona, Othello becomes enraged and vows to kill her. He also makes Iago swear that he will kill Cassio. Through Iago's planning, Roderigo gets a chance to kill Cassio but fails. When Iago sees Roderigo's failure to carry through with the plan, he wounds Cassio in the leg and kills Roderigo. When Othello hears commotion in the streets below he thinks that Cassio is dead and smothers Desdemona. When Cassio, Gratiano (relative to Brabantio), Montano (Cyprus official), and Iago hear Emilia's screams from Othello's bedroom they discover what he has done. Iago is revealed as the culprit and he then kills Emilia. After this Othello commits suicide and Iago is taken away to be punished. Iago was seeking a revenge that can be justified because he felt that Othello had had an affair with Emilia.

No such thing as one best way summary Essay

a. What are the authors trying to do in writing this? Whilst this is not empirical research and relies solely on theoretical arguments, Burns does demonstrate the shortcomings of the change contingency model. He attempts to show that organisations have choices which are not utilised which results in significant, negative, implications. b. What are the authors saying which is relevant to what I want to find out? Change could be planned but only in a stable environment. Change, in this situation would be, incremental, not transformational, and ignorant of a more direct approach and presumes that common agreements are reached. However Burns suggest the emergent approach is more important in turbulent environments and situations. He also argues that change is part of learning not just the opportunity to create something new. This idea does link to the contingency theory such that organisations and leaders can manipulate contingencies to align with their own styles and agendas. This is a negative aspect which could be viewed as morally incorrect. Change approaches must match the environment and situation though exercising choice base on alternatives not a single best way. c. How convincing is the author’s argument? Although not empirically based this is a good argument. Burns has a very good reputation in the field of change leadership/management. However it would be necessary to find additional evidence to support or counter these views. The RAVEN test is passed as there is no empirical research therefore we can imply that this paper is simply an academic view. d. In conclusion, what use can I make of this? This could be linked to the paper by Zhu et al to show how transformational leadership can be a good approach to ensure moral decision making and actions are present when dealing with emergent change as this requires a number of contingencies which leaders and followers could use too support long term organisational change.

Internet Law And The Economy Essay - 1399 Words

Internet Law and the Economy Introduction This weeks article review is taken from Ubiquity, an ACM IT Magazine and forum. The article is The New Economy: Are Rules Irrelevant? by Daniel W. Uhlfelder, Esq. In this article it is discussed how the new economy of the Internet move forward and enact laws that would be beneficial to all parties involved. This will be hard if not impossible because the Internet can cross boundaries where laws could not cross. The each country and each region uphold and maintain laws and regulations specific for their purposes. Therefore, jurisdiction is a key issue in order to determine what laws, regulations, taxation or other concerns apply. As crimes are committed our society and economy pays the†¦show more content†¦It is now important to know the different laws and develop new laws by which these new relationships interact. The key is to understand the different laws and how they are used, where and how should they be enforced and how to protect our interests and the interest of others and how we can use and develop laws to the best advantage of society. According to Daniel W. Uhlefelder Security, Internet taxation, electronic signatures, privacy, copyright, minority, small business development, and contract formation in cyberspace: These are just a few of the important legal issues members of the new economy are going to face. (Uhlfelder, 2000) Laws relating to our worldwide commerce are going to be needed to avoid ciaos in our economic society. If we cannot keep up with these changes, then there may be ill effects to our society and economy. Federal Trade Commission Chairman Robert Pitofsky reminds us that when enacting laws we must remember: Protect the marketplace, and dont undermine the incentives for innovation. And that is what this is about. The incentives for innovation seem to be very important in this area. On the other hand, you dont want people taking advantage of the fact that claming that ‘Well, Were high tech. The antitrust laws dont apply to us. That is not an acceptable defense.
