Development Partnerships in
Higher Educationprogramme
(DelPHE)
The UK Government's Department forInternational Development (DFID) through theBritish Council is supporting a newDevelopment Partnerships in Higher Education
programme (DelPHE).
The objective of this programme is to addressthe Millennium Development Goals through the
partnerships between Higher EducationInstitutions in the UK (HEIs) and 25 bilateralfocus countries.

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

Subdivisions of Electrical
Engineering
1. PowerSystems
These systems convert energy to and from electricalform and transmit energy over long distances,distribute energy to dwellings' and industrialcomplexes.
These systems are composed of generators,transformers, distribution lines, motors and otherelements.
2. Control Systems
These systems gather information with sensors anduse electrical energy to control physical process.

3. Electronics
Electronics is the study and application of materials, devices, andcircuits used in amplifying and switching electrical signals.
The most important electronic devices are transistors of variouskinds.
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 froma single Molecule - small enough to fit about 10 million transistorson the head of a pin.

6. Electromagnetics
Electromagnetics is the study and
application of electrical and magnetic
fields. Cellular telephones and televisionantenna 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 electricalsignals 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 maintainelectrical systems
To be able to communicate with electrical
engineering consultants To become an electrical engineer.

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 majorproject during the final year
Students will also learn how to apply
project management in their projects.
