ABSTRACT In the study of the influence of saliency ratio (L /L ) on the performance of a synchronous reluctance generator (SRG), this project investigates two typical generator rotor designs: Generator with cage and without cage otherwise known as cage and cageless rotor respectively. A special attention had been paid to the possible rotor geometries of synchronous reluctance machine, SRM. This ratio can directly influence our insight into the machine’s potential abilities. From the studi...
Predictive Analysis using Decision Tree, Random Forest and K-Nearest Algorithm
This project involves the use of an inductive sensor to control a robotic arm system. The signals generated in the induction coil will help in controlling the manipulator to perform certain gripping and grabbing actions. Also, the report describes the method used to acquire and process these induced signals before they are sent (induced signals) to the manipulator through the help of two programmed microcontrollers.
The main content of this project is to mathematically use the method of bilinear transformation to design a digital bandpass IIR filter, which will cut off frequencies below 20Hz and above 500Hz, since in electromyography the dominant frequencies for myopic signals lie between the frequency range of 20Hz and 500Hz.
ABSTRACT It would seem that hearing is a secondrate sense when compared to vision in our visually oriented modern society. People with hearing loss delay a decision to get hearing help because they are unaware of the fact that receiving early treatment for hearing loss has the potential to literally transform their lives. Research by the National Council on the Aging on more than 2,000 people with hearing loss demonstrated t...
Silica nanoparticles (SNPs) have been widely utilized in the oil and gas industry to improve different processes, such as in drilling operations, well cementing job, workover operations, wastewater remediation, and most importantly enhance oil recovery. Due to their particle sizes which ranges between 1 and 100 nm, large specific surface area, high dispersibility and tunable physico-chemical properties, they have the capability to alter the wettability of the reservoir rock and reduce the int...

ABSTRACT This research work studies the temperature effects in W-shaped core refractive index optical fiber. The work designs an optimized W-tailored optical fiber (OWTOF) that checks the effect of rising temperatures in W-tailored optical fiber (WTOF) for better communication. Initially, an introduction to the general concept of optical fibers including tailored optical fibers (TOF), temperature effects and models is presented as a background. This is followed by studies on existing litera...
ABSTRACT This study on the integrated solar and hydraulic jump enhanced waste stabilization pond (ISHJEWSP) is aimed at determining the effect of variations in solar radiation, hydraulic jump, hydro-kinematic factors and pond geometry, on the treatment efficiency of wastewater in the ISHJEWSP. An equation to account for these effects was derived, calibrated and verified. An empirical regression model for the prediction of the Biochemical Oxygen Demand (BOD5) in the ISHJEWSP for sewage treat...
ABSTRACT Noise Reduction in digital image is one of the most important and difficult techniques in image research. The aim of Noise Reduction in digital image is to improve the visual appearance of an image, or to provide a better transform representation for another automated image processing. Many images like medical images, satellite images, aerial images and even real-life photographs suffer from viewing, removing blurring and noise, increasing contrast, etc. Reducing noise from the dig...
ABSTRACT The increase in hazardous gaseous emission from the conventional source of energy has motivated many scientists to research on the alternate sources of energy which is cleaner. The chief source of renewable energy is the solar energy. The cleanness of this form of energy source motivated this research work. In this work, Modeling and Simulation of a Standalone Photovoltaic System aimed at increasing the efficiency of solar array system was developed. This work was undertaken to dev...
ABSTRACT This study examined the experimental analysis of sandcrete block production by using different sources of sharp sands in Enugu and Ebonyi State of South East Geo-Political Zone. As a result of the increasing cost of block production, many manufacturers and builders have resorted to using samples of sharp sand from different locations without appropriate consideration of the material constituents of the samples thereby, resulting in poor and undurable sandcrete blocks production. In...
ABSTRACT In Nigeria today it been observed that when changing from one GSM network operators to the other, customers has to give up their old numbers and adopt a new one. As a result, they face switching costs associated with informing people about changing their number, printing new business cards, missing valuable calls from people that do not have the new number, etc. In this research the Key Performance Indicatiors (KPI) of network providers and the causes of poor quality service qualit...
ABSTRACT The study aimed at investigating groundwater pollution in the vicinity of a municipal solid waste (MSW) dumpsite in order to reduce the risks of groundwater contamination and spread of water-borne diseases. To achieve this, the research tools used include model formulation, finite volume analysis, field collection of soil samples at Enugu Waste Management Authority (ESWAMA) dumpsite at various depths along radial sampling lines during wet and dry season periods. Heavy metals (Cu, Fe...
ABSTRACT A natural filtration on sludge drying bed has resulted to a modified equation incorporating the compressibility coefficient. The equation was derived using the application of a modified FMTLXLYLZ dimensional analysis technique. The equation was validated using experimental data from a pilot scale sand drying bed and there was a close agreement between theory and experiment with a correlation coefficient ranging from 0.94 to 0.98. The experimental slope and intercept was found to be ...
