In an effort to mitigate post-harvest losses (PHL) of agricultural products from farmers and the markets, greenhouse solar dryers (GSD) have been extensively employed by various stakeholders. The operation of these conventional GSD is though allowing cool or cold ambient air to enter them during...

This Dissertation investigates the effect of Denial-of-Service (DoS) attacks in Broadband- Wi-Fi networks involving public sector networks. Over the recent past, Wireless communications have become increasingly popular in our everyday life and the world has become increasingly mobile. Traditional...

The continued pollution from the mining activities in Zambia both legacy and current operations is associated with the weak and unclear existing environmental legislation coupled with poor institutional arrangement of enforcement and monitoring. Implementing policies that are weak and not in line...

In general, the study focuses on Evaluation of the Effectiveness and Efficiency of Compression and Decompression of IP Packets in a Wireless Local Area Network (WLAN). IP Packet Compression is the process of reducing the packet size before transmitting data in a Wireless Local Area Network...

A Wireless sensor network (WSN) is a fast-developing technology which can monitor, calculate, and communicate wirelessly thereby finding it’s place in areas such as defence, home automation, medical care and environmental sciences which demands better security, throughput, energy efficiency and...

Water is an essential product for human survival, which all age groups consume and access to safe drinking water is essential to health. Safe drinking water implies that the water does not represent any significant risk to health over a lifetime of consumption, including different sensitivities...

In any company, the planning and scheduling process is unavoidable. This research investigated its effects in the electrical section of Anvil Mining Congo SA. In this company, the focus of planning and scheduling, particularly on equipment, is on preventative maintenance rather than actions such...

Health Information Systems (HIS) are an integral part of a functioning health system. The SmartCare Electronic Health Record system is one such HIS implemented in Zambia. However, studies done on SmartCare HIS are limited when it comes to the success of the project from the developer’s view using...

The role of medical equipment is crucial for efficient healthcare delivery in any hospital. Physicians rely on equipment for the diagnosis and treatment of diseases. Therefore, the availability of medical equipment in good working condition and the optimal utilization of the equipment is...

Natural-convection solar tunnel dryers capable of achieving greater drying rates when drying products. The increased temperature decreases the relative humidity of the air, thereby allowing the air to more efficiently dry the product. However, it is necessary to provide an appropriate solar air...
