Uninterruptible Power Supplies (UPSs) are widely used for power conditioning applications, whereby the load is to be supplied with current and voltage waveforms containing minimal disturbance. A UPS also provides emergency power to critical loads in case of utility mains failure, and as such...

One of the main factors that led to this research on wind and solar energy hybrid application was the need to empower rural communities with communication technology, namely cellular phones which are now widely used in Zambia. A major constraint to the use of these devices in the rural areas is...

Today approximately one-and-half billion people around the world, especially in the developing world, use biomass based source of energy for cooking and heating. Conversion efficiency of the biomass in many cases is low resulting in unsustainable use of the biomass resource and negative...

Although traditional per-phase circuit has been widely used in steady-state analysis and design of induction motors, it is not appropriate to predict dynamic performance of the motor, In order to understand and analyze vector control of induction motors, the dynamic model is necessary....

The problem of infrastructure sharing among competing agents, each hoping to maximize its utility, is a daunting task for regulators and policy makers at large. This study used a game theoretical analysis of how a Network infrastructure as a Service (NaaS) company can optimize its utilities or...

This research was conducted so as to investigate the design and development of security applications that integrate fingerprint biometrics system into the military police database for the purpose of improving security in Military organisation. The research opposes manual procedures and modernises...

Access to health care is a human right, which includes having timely access to affordable and quality essential medicines at the right place and in sufficient quantity. However, inefficient public sector supply chain management contributes to constant shortages of essential medicines at health...

Production by pressing in its many forms together with sheet metal working constitutes one of the most absorbing branches of production engineering, and one which plays a vital role in domestic life, being largely responsible for many of the comforts which have been brought within the reach of...

The requirement for insolation models has been appreciated for many years in designing solar energy systems properly, for locations lacking insolation data base. Unfortunately, for most geographical areas in Zambia, insolation data is not available. This research thesis gives an account of global...

Zambia, like many other countries, has embraced Public Private Partnerships (PPPs) as a project delivery method. The country faces budgetary constraints which have made maintenance and provision of new infrastructure a challenge. PPPs seem to create opportunities which can stimulate investment in...
