ABSTRACT
Vegetable oils have traditionally been applied in food uses, but recent trends suggest their economic usefulness as industrial fluids. Increasing crude oil prices and emphasis on the development of renewable, environmentally friendly industrial fluids have brought vegetable oils to a place of prominence. Biodegradability provides an indication of the persistence of any particular substance in the environment and is the yardstick for assessing the eco friendliness of substances. The superior biodegradation of vegetable oils in comparison with mineral based oils has been demonstrated
severally,…

Weather monitoring is a global phenomenon and its impact world-wide cannot be over emphasized. The monitored parameters are always factored into result-based performance and efficiency. This efficiency can also be determined by the solar irradiance. Solar energy installations are some of the alternative energy generation strategy adopted globally, hence it is important to determine the location, size and position of the panel to ensure maximum solar irradiance. This work is aimed to study the effect of sun tracking solar installation…

Meteorological forecasting is an ever-challenging area of investigation for scientists. Multipath fading is considered to arise from irregularities of the atmospheric refractive index, called radio ducts. By these irregularities, radio waves propagations over this medium are adversely impaired. In this paper, Artificial Neural Network is developed for the purposes of modelling meteorological conditions of Abuja – Federal Capital Territory. The work uses meteorological parameters like temperature, pressure and relative humidity for the purpose of predicting duct presence in Abuja over…

Big Data and analytics are becoming a new technology focus both in science and in industry, thereby motivate technology shift to data centric architecture and operational models. While the quantum of large datasets is significantly rising, big data growth has brought about many challenging issues demanding remediation. This paper discusses the trends of big data and its applications in various disciplines, methods of analysis, benefits and its security challenge. For each component, detailed overviews of relevance and its applications were…

Electoral processes in Nigeria have, over the years been attended with numerous setbacks particularly in the conduct, coverage, computation and compilation of results as well as the considerable time-lag of results release which are altogether muffling the growth of our nascent democracy. This paper therefore proposed broadband deployment as a veritable tool to cater for easier collation of election results, fast transmission to designated and remote polling stations and quicker release of the final and acceptable results. It is believe…

Cellular radio transmissions over radio channels are subject to error bursts owing to the presence of deep fades resulting in the distortion, degradation of service quality and outages of cellular radio signals thereby limiting cellular network capacity, bandwidth requirements, and spectral efficiency. Simulation was carried out with randomly generated and uniformly distributed data in the range [0, M-1]. An Adaptive Modulation Scheme with receiver algorithm technique were employed for the estimation of channel variations which automatically selects the modulation levels…

Most Radio Communication networks located in coastal areas are potentially prone to anomalous propagation as radio signals very often experience outages and distortions, thereby causing some grave consequences on their dependant network supports. This is partly attributed to ducting phenomenon – a worst case of anomalous propagation in radio communications. In this work, AREPS is employed to characterize the tropospheric condition of Abidjan troposphere over which radio signals propagate. The results showed that in Abidjan, the altitude where pronounced ducting…
