The study examined the impact of Non-Oil Export in Nigeria over the period of 1980-2017.The specific objectives of the study are to examine the impact of Non-Oil export in Nigeria over the period under study and to ascertain the direction of causality betwee…

The study is aimed at modeling a single sided induction motor (SLIM) which will accelerate an elevator of a specified weight to a target distance with high thrust and efficiency by reducing end-edge effects on the motors. The observable problems associated w…

Harnessing wind energy to turn a turbine for power generation requires concentration of the wind at high velocity to give maximum and steady power output. Mathematical relationships are used to analyze the variation of the pressure and velocity of the flow r…

In this study, Taguchi robust design was used to design the experiment and optimize the mechanical properties of the hybrid composite while modeling and prediction of the mechanical properties was done using fuzzy logic. The hybrid composite was produced usi…

Horizontal axis wind turbine undergoes aerodynamic inefficiencies in the blade area due to many nonaerodynamic constrain which includes bareness of the blade, the gear box frictions, and the turbine. These constrain lead to great loss of power output of the w…

The main basic components for selecting modulation technique are Bit Error Rate (BER) and Signal to Noise Ratio (SNR). This paper examined the performance of different modulation in Multiple Input and Multiple Output Orthogonal Frequency Division Multiplexin…

The prediction of VLE data by conventional thermodynamic methods is tedious and requires determination of “constants” which is arbitrary in many ways hence there is need to adopt Adaptive Neuro Fuzzy Inference System with its associative property and its abi…

This work considers the replacement of Proportional Integral (PI) controllers with Proportional Resonant (PR) controllers in the single phase grid-connected inverter and the associated control technique which is always used in the photovoltaic power conditio…

Mammography is widely used in early breast cancer detection and prevention although it constitutes ionizing radiation (X-ray) properties of which continuous exposure could lead to chances of cancer. On the other hand, thermography operates under infrared and…

Soak-away are increasingly in use in the country due to absence of proper waste water sewage system. The effluent from soak – away may contribute greatly to ground water pollution. This study was undertaken to test some physical, chemical and biological char…

Quality of service (QoS) is a key performance indicator (KPI) that is used in determining the efficiency of telecommunication services rendered to end users. Accessibility, connection quality and retainability are major factors used in evaluating quality of …

The United Nations Commission on Environment and Development has defined sustainable development as one which allows nations to meet their present needs without compromising the ability of future generations of the citizenry to meet their own needs. This con…

Cognitive radio network (CRN), which has been adopted as a promising solution for optimization of the limited available radio-frequency spectrum, has two major drawbacks: Missed Detection (MD) and False Alarm (FA). This work proposed fuzzy-based intelligent …

This research investigated the sustainability of sisal/jute hybrid polymer composite for automobile application. Sisal/Jute hybrid polymers composite are of low cost, light weight, as well as possess satisfactory mechanical properties, easy making, availabil…

The aim of this experiment is to utilize locally available industrial waste products to produce binder for concrete production in order to minimise Portland cement consumption. This is achieved by using alkali- activated binder known as geopolymer which is a…

Intermodulation interference occurs when transmitters are co-located as well as in nonlinearity of the signal processing during modulation. This distortion in nonlinear systems are not needed in radio signal processing because they generate unwanted spurious…

This research presents the report of the optimization of esterification process using 2 4 factorial design to study the effects of temperature, mole ratio of bioethanol to ethanoic acid, catalyst concentration and esterification time on the yield of ethyl …

There are many control strategies employed in electric cable manufacturing industry to produce high quality products. In order to ensure good quality product formation, one requirement is to control the temperature of an extruder plant so as to form molten p…

Drugs are medicinal substances that are administered mostly orally and then metabolized in the gastro-intestinal tract (G.I.T) and subsequently assimilated in the blood stream. The paper highlights computerized solutions of a simplified mathematical model th…

This research investigated the sustainability of sisal/jute hybrid polymer composite for automobile application. Sisal/Jute hybrid polymers composite are of low cost, light weight, as well as possess satisfactory mechanical properties, easy making, availabil…
