The bad nature of the storage and transport facilities, overcooking and unnecessary spending causes a tremendous increase in food wastes in Nigeria which otherwise causes an environmental pollution to waterways and contributes to production of greenhouse gas emissions. This study evaluated the performance of an anaerobic bio-digester to generate bi...

Due to the high and fluctuating exchange rate, obtaining devices and equipment for practical demonstration of theoretical contents of engineering and applied science courses in developing countries is becoming a herculean task. To sustain the practical aspect of these courses, some of the devices have to be locally manufactured. In this study, a di...

The physically challenged, old-age people, and most paralysed patients need means of transportation from place to place to ease their movement. The earlier available wheelchairs are manually driven that need extra effort of either the physically challenged or an assisting person to move. Nowadays, the level of communication and socialization strong...

Development of a prototype inverter powered baking oven was carried out and performance was evaluated to determine its efficiency. The outer and inner dimensions of a designed and fabricated oven which were made up of mild steel and stainless steel were (506 length x 506 width x 506 height) and (436 length x 436 width x 436 height) in millimeters r...

A pyrolysis plant was designed, constructed and evaluated for the pyrolitic conversion of biomass into bio-fuel and chemical products. The plant comprising a mild steel retort of 4.27×10-3 m3 capacity, brick-lined clay furnace powered by a 2.0 kW electric heater, condensate receiver unit, gas collection/scrubbing units and accessories. The plant de...

Mechatronics system or robotics are present day technology which encompasses the incorporation of mechanical system, electronics and computer control in solving complex problem, increasing speed and precision while reducing stress for the human race. Motion and control are inevitable in mechatronics system and the essential element of the system th...

Design solution to failure of carport canopy structural frame under severe weather conditions is presented. The carport is conceived to be a single mast structure supporting an overhead retractable canopy operated by screw mechanism. The retraction of the canopy deny extreme weather conditions such as strong wind or heavy snowfall a surface area on...
