The shortfalls of fossil fuel, rapid depletion of reserves, nonrenewable, non-biodegradable, low lubricity, emissions of poisonous gases have resulted in the search for alternative energy source to fill the gap. This research work focused on synthesis, engin…

The rapid depletion of the world major energy source, the fossil fuel coupled with the numerous problems associated with its use has resulted in the search for renewable, sustainable and environmentally friendly fuel. Among the various options investigated, …

Over the years, OFDM (orthogonal frequency division multiplexing) has been the preferred wireless broadband multicarrier technology. Although it offers efficient power efficiency, good spectral efficiency and provides multipath propagation, it has several lim…

Analysis and prospect on Waste to Energy for electricity generation conducted within Aba metropolis establishes a knowledge that about 173.3million kg of waste per annum can effectively generate about 426.07GWhr to 883.32GWhr electricity per annum dependent …

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 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 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…

Presently, a good number of users with communication gadgets usable with second generation (2G) and third generation (3G) Wideband Code Division Multiple Access (WCDMA) accessible networks are prevalent especially in developing countries. These networks expe…

Energy demand is high and the so is the satisfaction derived from steady power supply. Power availability and steady supply promotes business undertaking in most localities. This in turn promotes economic growth and human wellbeing. There are serious challeng…

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…

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…

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…

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…

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…

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…
