  • This report was concerned with the situation of learning English for Engineering (EEE). It is fact that ESP subjects, especially EEE are worried problems. Although EEE is one of compulsory subjects, many students in FOFL, HUT did not get good marks and d06, k52 students were not an exception. The objective of this report was to investigate the advantages and disadvantages of learning EEE as well as the main reason why they did not get good mark in the final test.

  • This is the standard textbook for courses on probability and statistics, not substantially updated. While helping students to develop their problem-solving skills, the author motivates students with practical applications from various areas of ECE that demonstrate the relevance of probability theory to engineering practice. Included are chapter overviews, summaries, checklists of important terms, annotated references, and a wide selection of fully worked-out real-world examples.

  • a type of coaxial cable used to connect nodes on an Ethernet network. The10 refers to the transfer rate used on standard Ethernet, 10 megabits per second. The base means that the network uses baseband communication rather than broadband communications,and the 2 stands for the maximumlength of cable segment, 185 meters (almost 200). This type of cable is also called “thin”Ethernet, because it is a smaller diameter cablethan the 10base5 cables.

  • The aim of this chapter is to introduce electrical engineering. The chapter is organized to provide the newcomer with a view of the different specialties making up electrical engineering and to place the intent and organization of the book into perspective. Perhaps the first question that surfaces in the mind of the student approaching the subject is, Why electrical engineering? Since this book is directed at a readership having a mix of engineering backgrounds (including electrical engineering), the question is well justified and deserves some discussion.

  • The pervasive presence of electronic devices and instrumentation in all aspects of engineering design and analysis is one of the manifestations of the electronic revolution that has characterized the second half of the 20th century. Every aspect of engineering practice, and even of everyday life, has been affected in some way or another by electrical and electronic devices and instruments. Computers are perhaps the most obvious manifestations of this presence.

  • The use of a combustion engine to motivate a car has been questioned in recent times due to the increasing concern of warming. As a result of this, the concept of driving a car with an electric engine has become of particular interest. Dr. Geoff Walker and his PhD students are working on the creation of the Universitys own electric car. This thesis project is focused on deriving a control scheme to drive an induction machine that could be applied to the electric car.
