The economic advancement of any country depends on its ability to add value (through manufacturing) to its available local raw material resources. Zambia for a long time has been exporting copper as a raw material and importing finished copper products. This economic situation deprives Zambia of...

Malawi is endowed with a variety of mineral resources. Predominant among these are gemstones, industrial minerals, construction mineral materials and fuel minerals such as coal. However, most of these are small deposits, amenable by small-scale mining (SSM). Therefore, the promotion and...

This project describes the digital control of a radar that is ideally insensitive to alien disturbance signals. The key factor in this project comprises the design and realisation of a wide range of digital techniques combined into one digital controller consisting of several elements.The project...

In hard rock mining, drilling and blasting still remain the main method of fragmenting rock. In mining methods involving the use of long holes, extra costs are incurred as a result of consequences associated with hole deviations.The consequences include build-ups, hang-ups and poor rock...

Structural Dynamics Modification work often requires the inclusion of rational degrees of freedom in the modal data. These are not usually directly measurable because suitable transducers are not yet readily available. This work investigates the estimation of rotations from computed or measured...

In Zambia, like in many other countries, industrialisation has brought with it the problem of environmental pollution associated with industrial waste waters. The discharge of industrial waste water into public sewers may deteriorate sewer structures, increase maintenance costs, add problems in...

Artificial Intelligence (AI) based control techniques are becoming more popular for their applicability to complex control systems. In this research, an Intelligent Controller is designed for a non-linear process with complex dynamics - the Inverted Pendulum. The controller is designed to...

The objective of this work was to investigate the effects of the impulses induced by potholes on motor vehicle structures. MATLAB computer package was used to develop a computer program to carry out the tasks. This was done with a view to make recommendations in the nature and frequency of...

There has been an accelerated use of Computer Numerical Control machine tools by developed countries over the past decade resulting in manufacturing companies becoming more competitive on the world market. However, the initial cost of these machines is prohibitive to many companies in the third...

A numerical model for determining the size of a forced - convection solar fish dryer comprising of a drying bin (in which the fish is kept), aflat plate solar collector and a fan, has been developed. The model comprises of two sections with the first section calculating the technical parameters...
