Design of a manually operated paper recycling machine
(2017)Paper is used daily with learning institutions such as universities and schools being the main consumers. Due to its single usage it ends up being disposed hence most of the paper waste remains idle and unutilized although ... -
Technical analysis and subsequent optimization of a Solar Rural Mini Grid: Case of Mashaba PV Mini Grid-Gwanda
(2017)Electric power is a key driver of economic growth and prosperity. But access to electricity remains a distant dream for majority of the population living in the remote and arid areas of developing countries. With the growing ... -
Design of a sawdust pelleting machine
(IEOM Society International, 2017-04-11)This paper seeks to carry out the design of a pelleting machine with a capacity of 900kg per hour for the Company X. Apparently the boilers at the plant are using wood chips, a by-product from the milling operations as ... -
Solar mini grids in Africa
(2017-05-22)The technological advancement in telecommunications, engineering and agriculture has made electricity access a key factor for the development of any region in the world. The African continent has remained largely undeveloped ... -
A simple method of characterising Solar Thermal Water Heating Systems (SWHS) and the prediction of thermal and economic performance of the SWHS

Design of a Quality of Service Framework for Micro Grid Communication Network based on IEC 61850 Standard
(University of Zimbabwe, 2017)The micro-grid is a conceptual solution proposed as a better way to harness the potential of renewable energy generation and integration by offering a plug-andplay interface for various types of renewable generation ... -
Design of a rice transplanter for Zimbabwean farmers
(IEOM Society International, 2013-04-11)Rice is a crop of growing importance in Zimbabwe but with a production of only 700 metric tonnes. This is because in wetlands it is largely grown by broadcasting of seeds and seedlings; and manual transplanting of seedlings. ... -
Mathematical modelling and performance Analysis of Solar Chimney power generation in Zimbabwe
(University of Zimbabwe, 2017-06)This thesis analyzed the performance of a novel invention of Solar chimney power plants (SCPP) in Zimbabwe. Solar chimney power plants are based on the fundamental principle that hot air rises. The analysis was based on ... -
A model for an economic hybrid energy solution for a medium scale gold mine in remote Zimbabwe
(University of Zimbabwe, 2017-07-07)The growth in energy demand is surpassing generation capacity especially in developing nations. Traditional energy sources such as fossil fuels are finite and are the largest contributors to global warming due to emission ... -
Design of an Automated Powered Peanut Shelling Machine.
(Mechanical engineering, 2017-06)Groundnut is predominantly grown by communal farmers in Zimbabwe. The price of shelled kernel is approximately double that of pod. Hand shelling of peanuts is a time consuming and laborious process which is mostly used in ... -
Integration of physicochemical assessment of water quality with remote sensing techniques for the Dikgathong Damin Botswana.
(2016-12)Water quality has become a global concern due to ever increasing population and developmental activities that are polluting water resources. Botswana’s water resources are threatened by various pollution sources such as ... -
