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.

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

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.

5. ComputerSystems

Process and store information in digital form.

Computer is an essential electronicequipment 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 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.


14/22

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.


15/22

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 designelectrical

and electronic circuits

Analyses

ComputerSimulation

Building proto-type

Testing proto-type

Creating PCB layout

Produce final product


17/22

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.


18/22

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.
