Collaboration is critical to the successful implementation of construction projects; the sharing of knowledge and information on a construction project is one of the key factors of a successful contractual relationship. Currently, the visualization, coordination and management of project...

Recently, the use of Television White Spaces (TVWS) for broadband communication has raised interest world over. TVWS refers to regions of radio spectrum in the Ultra High Frequency(UHF)bandthatarenotusedallthetimeinaspecificgeographicallocation.TVWS spectrum brings with advantageous propagation...

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...

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...

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...

Structural Health Monitoring by use of Visual inspections of bridge structures can be subjective and inaccurate. Recent developments in sensing, communication and information technologies, however, have completely modernized the inspection procedures and significantly increased the efficiency in...

The practice of copper wire drawing has faced problems regarding process, quality and manufacturing cost and satisfying world market demand of drawn wires. Of great importance to the practitioner are problems due to the interaction of process parameters during wire drawing. The present research...
