Modelling of Adsorption Efficiency for the Removal of Lead and Copper from Waste Water

Abstract  The focus of this research work is to derive a model that will be used to obtain the adsorption efficiency of an adsorbent for the removal of lead and copper from waste water. To date, the prevalence of adsorption separation remains an aesthetic attention and consideration abroad the nations owning to its low cost, simplicity of design, ease of operation, insensitivity to toxic substances and complete removal of pollutants even from solutions. The data points for this work were col...

Use of the Swat Model to Evaluate the Impact of Land-Use Change on Ebonyi River Watershed

ABSTRACT SWAT was applied a large watershed (3,765km2 ) in south-eastern Nigeria, to predict streamflow and sediment discharge from the Ebonyi River Watershed using globally available data downloaded from the internet. Digital elevation, land-use and soil maps of the study area from global databases and historical weather data measured locally were used. SWAT model was setup to use the MapWindow GIS interface. The model predicted an average daily streamflow and sediment discharge of 24.32m3 ...

Influence of Saliency Ratio (Xd, Xq) on the Performance of Three-Phase Synchronous Reluctance Generators.

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...

Robotic Manipulator using an Inductive Sensor

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.

MODELLING AND SIMULATIONS OF A DIGITAL BANDPASS IIR FILTER

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. 

The Design and Construction of A Mobile Station Compatible Hearing Aid (with Volume and Pitch Control)

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...

Silicia Nanoparticles for Enhancing the Performance of Waterflooding in Oil Reservoirs

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...

Design and Optimization of W-Tailored Optical Fiber

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...

Integrated Solar and Hydraulic Jump Enhanced Waste Stabilization Pond

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...

Design of Digital Image Enhancement System Using Noise Filtering Techniques

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...

Modeling and Simulation of a Standalone Photovoltaic System

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...

Analysis of Sandcrete Blocks Production by using different Sources of Sharp Sands in some Parts of South-East Geo-Political Zones. A Case Study Enugu and Ebonyi State

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...

An Improved Model for Key Performance Indicators Analysis for Mobile Number Portability Scheme for GSM Subscribers in Nigeria

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...
