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...

Tomatoes and cabbage samples were analysed for chlorpyrifos and monocrotophos residues by Gas Chromatography (^GC) vntYv electron capture detector. One field o? tomatoes and cabbage was treated for four weeks at the recommended dose of 0.61/Ha monocrotophos and 21/Ha chlorpyrifos. A second field...

The content of cadmium and lead in raw food crops consisting of cabbage, rape, tomato and maize collected from selected retail markets, and in daily diets collected from selected school dining halls in Kabwe and Lusaka was determined. Separate analyte solutions were obtained after wet digestion...

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...

Several 5-0-toluene-p-sulphonyl and 5-iodo derivatives of «-and 3-ribofuranoses and «-xylofuranose have been prepared in order to study their reactions with sodium hydrogen carbonate in dimethyl sulphoxide. Similar reactions are known to convert acylic primary sulphonates and iodides to aldehydes...

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...

This study looked at the perceptions of environmental hazards and disasters in Zambia’s college geography education. The problem investigated by this study was that lecturers and students took what they taught and learnt respectively on the topic of ‘environmental hazards and disasters’ for...

This study investigated the prevalence and nature of mathematical difficulties among grade five pupils in selected schools of Lusaka Province. The objectives of this study were: • To establish the proportion of fifth graders that experience difficulties in mathematics in selected schools in...
