• An overview of typical electrical engineering
  department
• Subdivisions of electrical and electronic
  engineering
• Power systems, control systems
• Electronics
• Communication
• Electromagnetics
• Computer systems
• Signal processing
• Reasons for studying electrical engineering
• Different categories of subjects within EE
• Running a professional EE department

Development Partnerships in Higher Education
programme (DelPHE)

• The UK Government's Department for International
  Development (DFID) through the British Council is
  supporting a new Development Partnerships in
  Higher Education programme (DelPHE).
• The objective of this programme is to address the
  Millennium Development Goals through the
  partnerships between Higher Education
  Institutions in the UK (HEIs) and 25 bilateral
  focus countries.

Progress so far

• 1st set of activities Started the project,
  December 2006
• 2nd set of activities March April 2007
• Training for lecturers and computer science
  students in digital electronics
• Further information published at the following
  website

OVERVIEW

• Electrical Engineers design systems that have two
  main objectives
• To generate, distribute, store and convert energy
  between various forms
• To gather, store, process, transport and present
  information

6
Subdivisions of Electrical Engineering

• Power Systems
• These systems convert energy to and from
  electrical form and transmit energy over long
  distances, distribute energy to dwellings' and
  industrial complexes.
• These systems are composed of generators,
  transformers, distribution lines, motors and
  other elements.
• 2. Control Systems
• These systems gather information with sensors
  and use electrical energy to control physical
  process.

• 3. Electronics
• Electronics is the study and application of
  materials, devices, and circuits used in
  amplifying and switching electrical signals.
• The most important electronic devices are
  transistors of various kinds.
• In 1947, Transistor was invented in Bell labs in
  the USA.
• It was as tall as the face of wristwatch.
• In November 2001, another Bell lab team has built
  a transistor from a single Molecule - small
  enough to fit about 10 million transistors on the
  head of a pin.

Subdivisions of Electrical Engineering (cont.)

• Overview of Electronics
• Analogue electronics
• Digital Electronics
• Power electronics
• Physical electronics

9
Subdivisions of Electrical Engineering (cont.)

• History of Electronic Devices
• Information on different generation of electronic
  devices which were presented on page 9 -14 on can
  be found the following link in this website.
• http//www.uobkupartnership.talktalk.net/page13.ht
  m
• Because of the limit on memory pages 9 -14 have
  eliminated from this version of presentation.

10
Subdivisions of Electrical Engineering (cont.)

• 4. Communication Systems
• Transport information in electrical form.
  Cellular telephones, radio, satellite television
  and the internet are examples of communication
  systems.

11
Subdivisions of Electrical Engineering(cont.)

• 5. Computer Systems
• Process and store information in digital form.
  Computer is an essential electronic equipment in
  the lives of people at the developed world.

12
Subdivisions of Electrical Engineering(cont.)

• 6. Electromagnetics
• Electromagnetics is the study and application of
  electrical and magnetic fields. Cellular
  telephones and television antenna and magnetron
  (a device in the oven) are examples of
  electromagnetic devices.

13
Subdivisions of Electrical Engineering(cont.)

• 7. Signal Processing
• Is concerned with information-bearing electrical
  signal. Often, the objective is to extract useful
  information from electrical signals derived from
  sensors. Application are machine vision and
  robotics.

14
Reasons for studying electrical engineering

• To have a broad enough knowledge base so that one
  can design project in their fields.
• To be able to operate and maintain electrical
  systems
• To be able to communicate with electrical
  engineering consultants
• To become an electrical engineer.

15
Subjects within EE

• Fundamentals
• Math, Science
• Core subjects
• Circuit analysis, analogue and digital
  electronics, Signals and systems, Control,
  microprocessors, Communication, computer
  programming
• Specialty
• Specific subjects in different areas

16
Steps to design electrical and electronic circuits

• Analyses
• Computer Simulation
• Building proto-type
• Testing proto-type
• Creating PCB layout
• Produce final product

17
Running the department

• Strong leadership is required
• Subject leaders are required
• Update curriculum by integrating advances in
  technologies
• Research and consultancies
• Close collaboration with other universities and
  colleges
• Offer courses, which are shared with local
  colleges.

18
PROJECTS

• An essential part of any engineering course.
• The students must complete some small project in
  earlier years and a major project during the
  final year
• Students will also learn how to apply project
  management in their projects.
