Thirty four out of forty (85%) TAZARA Diesel Electric (DE) locomotives were operating with either defective or no speedometer system at all. This compromised the safety of locomotives and peoples’ lives. As a result of financial challenges, TAZARA was unable buy new DE speedometer system costing...

Design and construction practices in Zambia have tended to neglect the risk posed by seismicity on structures, and no earthquake design and construction guides exist. The recent earthquake occurrences suggest that earthquake incidences can no longer be ignored. The research studied the occurrence...

This study sought to investigate the cause of the frequent drill rig breakdown at Lubambe Copper Mines (LCM) in Zambia. A multimethod approach was adopted. The result of the study showed that human factors, environmental factors, maintenance factors and Supply Chain related factors were the cause...

The health sector has seen tremendous increase in the construction and expansion of physical infrastructure. Much of this infrastructure development has been spearheaded by donors who have facilitated the funding and construction of these structures. Presently, most funders are moving away from...

Active analogue self-interference cancellation (AASIC) techniques are used to prevent the saturation of the receiver chain in full-duplex (FD) radios. This is done by cancelling the self-interference (SI) signal before it enters the receiver chain. AASIC techniques are usually implemented...

The construction industry is an important sector in the economies of nations and plays a key role in socio-economic growth of Zambia. Construction projects in Zambia fail to meet owner’s performance expectations. Increased cost-effectiveness and reduced waste in Architecture, Engineering and...

The University of Zambia is experiencing increasing challenge of car parking space and vehicle access controls to and within campus premises. Vehicles have been stolen without being detected. There has not been any effective means of recording and tracking vehicle activities in and out of campus....

In machining operations, the effects of high temperatures are i) reduction in tool life, ii) production of hot chips and iii) inaccuracies in workpiece dimensions. Coolant is applied to convey away heat to extend tool life and ensure a good surface finish of the workpiece. While conventional...

Mining method selection is one of the most critical activities of Mining engineering with the ultimate goal of maximizing profit, mineral recovery and arrive at a method with the least problems among feasible alternatives. The geology at the Synclinorium is complex with four main lithologies i.e....
