The design and development of ytterbium-doped fibre lasers (YDFLs) operating around 1018nm laser wavelength and pumped around 976nm has advanced in technology since the first ytterbium laser was tested in 1988. The fiber lasers are used in various sectors such as communications, material...

This research investigated the vulnerabilities of Graphics Processing Units (GPUs) to Denial-of-Service (DoS) and Memory Exploitation sidebar attacks on Windows Operating Systems using recovery time. The simulation results showed that all three Windows operating systems and their respective GPUs...

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...

The use of renewable energy sources is one of the crucial components of the contemporary issues of sustainable development. Sustainable energy development gives a rationale to have resources that are economical, environmentally friendly and whose social effects are acceptable. However, the...

The swift expansion of Mobile Phone Technology in the developing world has created rapid development and deployment of a wide array of Potential Applications, including Mobile Banking, Data Collection, Patient Tracking, and Behavioural Interventions which has allowed many Organizations to Monitor...

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)...

Concrete is one of the most widely used construction material in the world and the construction industry is looking for ways of making concrete using greener methods so as to reduce ecological effects on the environment that come as a result of large scale exploitation of natural aggregates. The...

Insurance is a contract of reimbursement against specified risks such as fire, earthquakes, floods, theft. (Mayer 2010). The Zambian Insurance industry has over 40 General Insurance providers, offering Insurance products and services to only 2.8% of the population (I.A.Z, 2018). However, in their...

The purpose of the research was to assess the impact of the two types of solar photovoltaic technologies which are available in our rural communities in Zambia. This study presents the results of socio-technical assessment of solar photovoltaic interventions namely solar home systems (SHS) and...
