The acceptability of palm oil as edible cooking oil, as well, as for industrial uses is limited to the associated impurities and the need to improve on its quality to meet the required standards for both human and industrial uses through bleaching, form the b…

In LTE systems, handovers have to be glitch free and very fast because, unlike earlier mobile communication technologies, it does not support soft handover but instead it supports only hard handover and this makes handover particularly challenging in LTE net…

The work explored the thermal degradation of waste plastics from Asaba metropolis in a locally fabricated batch unit for pyrolysis of the waste feeds and the optimization of pyrolysis yield. Special attention was given to Low Density Polyethylene (LDPE), High…

In this research, the average grain size and mechanical properties of aluminum-magnesium alloy doped with nickel were predicted using Fuzzy logic. The single input to the Fuzzy logic model was variation in percentage weight of nickel, while the multiple outpu…

Wireless sensor nodes serve as both sensing and routing devices which are generally employed to send data from the primary source node to the destination node (or sink node). There are distinct procedures that wireless sensor networks (WSN) takes when put in…

This paper proposes C-band non-Foster enhanced high power (17.8 W) class-J GaN HEMT (gallium nitride high electron mobility transistor) amplifier. The negative capacitance generated by the non-Foster circuit (NFC) in the input matching network of Class-J pow…

The research work evaluated some outlier detection techniques such as t-statistic (T), Modified Z-Statistic (τ ), Cancer Outlier Profile Analysis (COPA), Outlier Sum-Statistic (OS), Outlier Robust T-Statistic (ORT), and the Truncated Outlier Robust T-Statist…

This paper proposes high power high efficiency Class-J GaN HEMT amplifier with non-Foster network. NonFoster network forms part of the input matching network of the power amplifier (PA) and cancels out the power transistor input parasitic capacitance thereby …

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…
