1.1 Brief History

The present course of study offered by the Department of Electrical and Computer Engineering (ECE) in the Faculty of Technology (FoT) is an outgrowth of past programs. In its first inception as a course of study in the former college of Engineering in the late fifties, electrical engineering was given as a sub-discipline in a combined Industrial Engineering program, which also included mechanical engineering. As the need for better-trained electrical engineers began to be felt, a separate department was established with two divisions, namely electronics and power engineering. Students were required to join the Department at the 3rd year level, after completing a common one-year pre-engineering program. Selection of one of the two options (i.e. majoring in one and minoring in the other) was made at the 4th year level. On the whole, the program had a significant merit in that it afforded technical organizations the chance to recruit directly electrical engineers with the desired fields of major study.

By 1968, the two EE streams were, however, seen to be either too specialized for local employment requirements as the job opportunities were in any case getting filled very fast. Accordingly, as part of an overall reorganization of the teaching programs of Addis Ababa University (AAU) (formerly Haileselassie I University, HSIU), a unified five-year EE program was launched in 1969. This program remained in effect until 1977, when the university administration instructed all Departments of the FoT to devise new four-year Engineering degree programs. To achieve this, the EE Department, and the Faculty as a whole, had to eliminate many common education courses in the freshman and sophomore years and begin engineering courses at the 2nd Semester of the freshman program. Moreover, the Department eliminated some overlapping of courses in its five-year program. With such changes the Department managed to make the new and old programs essentially equivalent, regarding core departmental courses. Later, it was realized that the 4-year program was too much of a burden for the students, as they had to take 21 credit hours per semester. So, as of 1983, the old five-year program was revived and as the Ethiopian staff became more matured and more qualified, the program was sufficiently developed. Additional and very essential courses such as digital techniques and applications, microprocessors, elements of computer engineering, power and communication systems were gradually introduced. Graduates of the EE/AAU have since been gainfully employed by different technical organizations within and outside Ethiopia.

Later, the AAU/EE departmental program was further expanded to include an evening five-year EE Advanced Diploma program, an evening nine-year EE degree program, and a two-year M.Sc. program.

 2.1 Undergraduate Program

The department runs three programs:

2.1.1 Regular program:

This covers the B.Sc. and M.Sc. degree programs in electrical and computer engineering. The duration of the B.Sc. program is 5 years and that of the M.Sc. program is two years. However, it M.Sc. program may take more than two years.

2.1.2 Computer Engineering Stream:

This program, approved in 1994, has been incorporated as a main program of study since February 1998. It is now given as a specialization at the senior year level. Revisions are, however, being done by the Department to give a full-fledged Computer Engineering Program. This envisaged program would be launched shortly at the 2nd year second semester level.

2.1.3 Continuing Education Program:

This covers the evening B.Sc. and Diploma programs. Similar courses are offered in both the regular and the evening B.Sc. programs and the total credit hours required are the same. When evening students reach the equivalent of the fifth year of the day program (this is usually after 9 years of study), the evening degree students are transferred to the day program. On the other hand, the evening Advanced Diploma program is a 5-year program.

At the undergraduate level, there are two approved streams, i.e. the general electrical engineering stream and the computer engineering stream. The later stream was launched in Feb. 1998.

 2.2 Graduate Program

 

In the M.Sc. program, there are four approved streams: communication, power, electronics and control engineering. At present, only the communication and control streams are given. The other two are not given due to lack of specialized staff in the field. A total of 30 credit hours of course work and 6 credit hours of project work are required to complete the graduate program. In the invisaged new program, the Computer Engineering stream is also offered as one main area of specialization.

    4. FACILITIES

    maroonline.gif (2801 bytes)


    The ECE department has instructional facilities for approximately 200 students. The classrooms are conducive for teaching in terms of ventilation, light etc. (but there are shortages of seats). It can be said that the laboratories are sufficiently equipped. Currently about 50 students are handled in the laboratories that were intended for 25 students at a time. Though this makes the student/lab ratio high, the situation is still manageable. However, plans are underway to improve the laboratory situation. The laboratories of the department are in the areas of control, communication, fundamentals of circuits, high voltage, machines, networks, microprocessor (computer) and instrumentation. Besides, there is a general-purpose workshop. The safety precautions in the laboratories and workshop are good.

    The students of the department have also access to the Faculty Computer Center, which contains a number of PCs operating in a network (Windows NT & Linux) and associated peripherals. The students have also access to a library, which is located within an easy reach of the staff and students. In addition to the main library, there is a graduate collection branch for use by graduate students and academic staff.

    5. RESEARCH ACTIVITIES

    maroonline.gif (2801 bytes)


    The research activities in the Department may be divided into pure research and preparation of teaching materials and textbooks. The former includes staff research, graduate students’ thesis research and senior project of undergraduate students. Currently there is one major research project in the Department and that is: "Performance Evaluation of a Photovoltaic System as Applied to Water pumping". The objective of this project is to utilize solar energy to pump water for irrigation purpose.

    With regard to the preparation of teaching materials, the Department is rather strong. To date, a number of teaching materials have been prepared by the staff members on various sub-disciplines. These include Communication Theory, Control Engineering, Electrical Machines, Electromagnetic Fields and Waves, Engineering Electronics, Instrumentation Engineering, Laboratory Manual for Electrical machines, Signals and Systems. Out of these, Control Engineering, Electrical Machines, Engineering Electronics and Instrumentation Engineering have already become textbooks. Currently two teaching materials, one on Signal Processing and the other on Computational Methods are under preparation.
