The aim of this study is to assess the availability of steam and gas turbine units of a thermal power station using Markovian Approach. Operational data from 2003 to 2012 were collected from a thermal power station in Nigeria. These raw data represents records of plant generation capabilities as...

This work attempts to satisfy the desire to meet the energy demand in schools and most rural areas, Net Present Value (NPV) and Internal rate return (IRR) were employed in determining the economic viability of solar panel installation in a rural area for the purpose of providing alternative...

The predominant use of fossil and wood energy sources in Nigeria has contributed immensely to environmental pollution and related health challenges; this has prompted an increasing demand for other cleaner and sustainable energy sources such as solar cookers. In this study, design and thermal...

Technical education, as entrenched in the Nigerian National Policy on Education, is concerned with qualitative technological human resources development directed towards a national pool of skilled and self-reliant craftsmen, technicians and technologists in technical and vocational fields. The...
