Many studies are on-going to optimize the properties of composites, this is because composite have found application in different industries due to their advantage of light weight. Scientists have turned their attention to using natural occurring materials for the development of novel materials. Animal waste is playing an important part in this area of application as using it is not only providing benign environmental solution but solving engineering challenges. In this study, the effe...
ABSTRACT Samples of laterites classified by American Association of State Highway and Transportation Officials (AASHTO) as A-7-6 and A-7-5, collected from two different borrow pits in Ado-Ekiti were tested for the assessment of their geotechnical properties in natural and stabilized states. The research is aimed at assessing effects of sawdust ash (SDA), lime and the combination of sawdust ash and lime (SDAL) on the properties of the soil samples. The samples were subj...
Abstract: In this study, a miniature fluidised bed boiler for steam generation was designed and constructed. The boiler ismade up of a steam drum, combustion chamber, downcomer and riser tubes as a heat exchanger, a non-return valve andsuperheater tube. Experimental investigation on the fuel distribution was carried in two-dimensional chamber with crosssection of 500 mm x 1000 mm and bed height of 77 mm, 47 mm and 27 mm. The results obtained from the performanceevaluation of the fluidised bed...
Supreme likelihoods of fire disasters in buildings from consulted literatures includes: abnormal rise in temperature, gas leakages from gas cylinders and her accessories, and increasing concentration of smoke from burning materials. On this premise, three respective sensors were saddle with the responsibility of monitoring any anomalies from the aforementioned likelihoods of fire in market shops of which their presence above threshold possess a treat to lives and properties. These sen...
As the world population increases more than ever before and increasing demand on food, feed and fiber, and security, the number of off-the-road vehicles is rapidly increasing for agriculture, forestry, military, mining and construction industries. Many researchers have studied and still investigating traction as it relates off-road vehicles and publications abound especially from developed countries of Europe, America and others. In our generation scientists are trying to put robotic vehicles...
Research on soil-wheel interaction is essential in studies of motion resistance of narrow wheels of agricultural machines. The aim of this research was to study the effects of soil moisture content and tyre inflation pressure on motion resistance of narrow wheels using a locally developed single wheel test rig. A single wheel Test Rig facility was developed at Federal University of Technology, Akure. It consists of a soil bin, carriage, single narrow wheel tester, trolley and drive system. An...
Abstract- Two different samples of soil tested as A-7-5 and A-7-6 were stabilized respectively with lime and cement. The samples were stabilized with the additives in steps of 2% and subjected to laboratory tests such as consistency limits, compaction, California bearing ratio (CBR) and unconfined compressive strength (UCS) until it reached 10% additives by weight of dry soil sample. The Proctor energy type of compaction and soaked method of CBR was adopted for the research while the compress...

Limited or poor food separation techniques into fine particles for further processing cause post-harvest losses of food crops and initiates the problem of food and nutritional insecurity in Nigeria. In order to solve this problem, food crops need to be processed into a lasting and nutritious consumable form through the use of mechanization. Different materials in powder form or solid form are separated by using two-level screening machines. This machine can be used in different industries lik...
Abstract Vocational and Technical Education (VTE) is one of the manpower development programmes of study that is attracting the attention of various countries around the world. Numerous studies on Didactics have demonstrated the effectiveness of student centered methods and strategies to improve results in terms of knowledge, skills, attitudes and values in Technical and Vocational Education and Training (TVET). With the continuous advancement of technology, computer technology has infiltrate...
Abstract. The importance of brake systems in automobiles cannot be overemphasized. Brakes are used in speed control of vehicles and do so by the conversion of kinetic energy into thermal energy. Better stopping performance has favored the disc brake system over the drum brake system and has found wide application in high-performance vehicles. Brake fade, caused by thermal overload has placed a limit on the permissible temperature at which braking systems can function, and it is the task of de...
ABSTRACT The metering device is a key segment of planters that legitimately influence crop improvement and yield dependent on the presentation of the specific design. Metering device B (Teflon) is intended to minimize seed damage during planting while improving metering efficiency and field capacity. An improved local jab planter for maize seeds which is adjusted for farmers developing under two hectares has been structured, built and tried. The major components of the planter are hopper, see...
The growing gap between electric power generated and that demanded is of utmost concern especially in developing economy, hence calling for measures to argument the existing power generated of which DG is a more viable aspect to explore in curtailing this challenges; although been confronted with issue of location and sizing. This research applied Adaptive neuro fuzzy logic technique to optimize DG location and size. A 24 bus radial network was used to demonstrate this process and having a su...
Fuzzy logic, being a very robust artificial intelligence technique, was employed to forecast short term load in this work. The algorithm was demonstrated with the help of seven months average daily load data collected from Power Holding Company of Nigeria (PHCN). The outcome realized from the model or simulation illustrate that the projected forecasting technique, which propose the use of weather alteration such as temperature and humidity, gives load forecasting results with substantial prec...
The growing concern for the need to reduce the gap between power generated and power consumed in Nigeria is on the increase. Many measures and policy have been geared by Nigeria Electricity Regulatory Commission and Ministry of Power to revamp the generation aspect of the country power sector but the impact is yet to be felt as the amount of power still generated is far below par compared to other countries. Nigeria average power generation stands at an average of 5800 MW. With the call to...
