While mechanization is known to enhance production and reduce drudgery, powering agricultural machinery entails energy consumption withattendant financial and environmental costs. Financial costs in agricultural mechanization is exacerbated by the rising energy prices due to ongoing energy sector liberalization and this has negative impact on the p... Continue Reading
Rice husk, a potential source of activated carbon, is locally available in Nigeria but underutilized thereby constituting solid waste menace in the environment. Incidentally, large volume of wastewater containing high concentrations of toxic contaminants such as phenol and other contaminants are continuously being generated as a result of increased...

In this study, the effects of methanolic leave extracts of Combretum micrantum (CM), Combretum Glutinosum (CG), Ficus exasperate (FE) and Ficus platyphylla (FP) on the corrosion of A356.0 type Al-Si-Mg alloy in 3.5 % NaCl aqueous solution were determined. It evaluated the inhibition efficiency of each of the inhibitors and determined their mechanis... Continue Reading
This research is aimed at the development of a cultural-algorithm based artificial bee colony algorithm (CABCA) for improved Proportional Integral Derivative (PID) controller parameters tuning. The normative and situational knowledge inherent in cultural algorithm were utilized to guide the step size as well as the direction of evolution of Artific... Continue Reading
All nations of the world depend on fossil fuels for their energy needs. However the obligation to reduce Carbon dioxide and other gaseous emissions is the reason behind which countries turn to non-polluting renewable energy sources. Hot water heated by the sun is used in many ways, in residential settings to provide domestic hot water, also has ind... Continue Reading
Agricultural products upon harvesting have high moisture content which makes it unsafe for storage as the moisture in the crops attracts microorganisms which result in deterioration of the products. The major shortcoming of multiple trays drying is uneven drying of the products being dried on different trays.Solar dryers with and without thermal st... Continue Reading
There are several energy saving algorithms proposed to save energy in heterogeneous networks, but most of these algorithms achieved energy savings at the expense of service provisioning. Base stations significantly contribute to power consumption in cellular networks. This research work presented a Data Rate-Based Sleep Mode Algorithm for energy sa... Continue Reading
The present day cellular network faces an increasing problem of providing capacity and coverage for users. The Long Term Evolution (LTE) system provides a number of ways in vi mitigating these problems among one of which is the deployment of femtocell technology. The femtocell is an example of a heterogeneous network which comprises of different la... Continue Reading
This research work presents the development of a position and trajectory tracking control of ball and plate system. The ball and plate control system was considered as a double feedback loop structure (a loop within a loop), for effective control of the system. The inner loop was designed using linear algebraic method by solving a set of Diophantin... Continue Reading
This research work presents the development of an improved ergodic capacity of underlay Cognitive Radio (CR) with imperfect Channel State Information(CSI). An underlay CR network under a Peak Interference Power (PIP) constraint imposed by a Primary User (PU) was considered .A closed former godic capacity expression of the Secondary User (SU)under P...

This research presents thedevelopment of an improved Intrusion Detection based Secured RObust Header Compression (IDSROHC)techniquefor handling brute force attack. The secured RObust Header Compression (secured ROHC) was developed to secure Internet Protocol version six (IPv6) packets against false initial refresh attack by encrypting the cyclic re...

This study was carried out to examine the effects of Single Super Phosphate with Wood ash on the production of biogas from Cow Dung and Chicken Droppings mixed with Digitaria Smuts II. An existing digester design was adopted (3 in 1 floating drums) and fabricated using locally available materials to digest Cow Dung from Kawo Abattoir, Chicken Dropp... Continue Reading
Optimal siting and sizing of Distribution Flexible AC Transmission Systems (D-FACTS) devices in power distribution networks maximizes loadability, compensates reactive power, minimizes power loss and enhances voltage profile. The search for optimal size and locations of these devices in radial distribution networks is challenging and requires robus... Continue Reading
The water supply infrastructure in Kaduna North Water Works (KNWW) has faced alot of problems, partly due to a neglect of the components over a long period and with tariffs at a low level, which was far from reflecting the real cost of the service. Economic efficiency still remains below the regional average, resulting in the lack of financial reso... Continue Reading
