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...

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...

Pumps, of varying designs, have historically been vital in fluid flow. In Zambia, typical applications could be found in domestic water supplies and industrial applications. Complete pumping units have been designed and manufactured elsewhere. The manufacture of pumps in Zambia has generally...

The Post Jomtien Conference of March 1990, in Thailand, has seen the Zambian Government directing its efforts to providing quality education to all, for economic and social reasons. However, these efforts have been constrained by problems such as lack of qualified teaching staff and teaching and...

The continuous quest for modernization and industrialization has brought a great challenge upon the third world countries such as Zambia in that these countries have to keep on importing production machinery whose spares cannot be obtained locally but from outside. This problem has been...

In this study a case for the automation of circulation control is made.The philosophy of circulation control is presented.A circulation control model upon which various manual-based and computer-based systems are compared for effectiveness, is developed.A general review of the environment of the...
