The visionary concept of extended producer responsibility (EPR) policy advocates a system that aims to increase waste recovery and recycling. Extended producer responsibility policies have been widely adopted since the 1990’s, particularly in developed countries as an effective instrument for...

A number of research concerns have arisen in the concrete research community on the fire resistance of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) beams, despite their improved mechanical properties at ambient temperature. The traditional experimental approach to performance-based...

This study investigated the understanding which University of Zambia (UNZA) first year students of mathematics had of specific concepts in selected mathematics topics. Procedural and conceptual understanding underpinned the investigation. It was also the intention of the study to determine...

Floods have been one of the recurring hazards with increased magnitude in Botswana due to heavy convective rainfall and tropical cyclones effects which eventually cause flood disasters. Gaborone is one of the areas hardest hit by floods in Botswana, yet the country is always caught off guard by...

The concept of hyperconvexity in metric spaces was introduced by Aronszajn and Panichpakdi in 1956. This concept was then generalised to the framework of quasi-metric spaces by John Isbell in 1964, which he called Isbell convexity. In 2019, Yi git and Efe generalised this concept of...

This dissertation investigates the effect of spectral efficiency as the number of service antennas and number of users in Multiple-input Multiple-output (MIMO) Long Term Evolution (LTE) network increases. The channel estimators studied namely Zero Forcing (ZF), Minimum Mean Square Error (MMSE)...
