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

following website:

OVERVIEW
• Electrical Engineers design systems that
have two main objectives:
1.To generate, distribute, store and convert
energy between various forms
2.To gather, store, process, transport and
present information
Subdivisions of Electrical
Engineering
1.
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.

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

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.

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.

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.
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.
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
Steps to design electrical
and electronic circuits
•
•
•
•
•
•
Analyses
Computer Simulation
Building proto-type
Testing proto-type
Creating PCB layout
Produce final product
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.
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.
