ABSTRACT The basic idea deals with detecting the voltage collapse ahead of time to provide the operators a lead time for remedial actions and for possible prevention of blackouts. To detect cases of voltage collapse, pattern recognition in conjunction with power system simulator for engineering (PSSE) program was created and then deployed in Nigeria 330KV integrated power system to develop Regularized Least Squares Classification (RLSC) as well as Classification and Regression Trees (...
This thesis proposes a Restricted Radix-7 Symmetrical Quaternary Signed Digit Number system (RR7SQSDNS) both as an alternative processing logic threshold system and as a signed digit algebraic structure. The thesis also presents the arithmetic operations on elliptic curves defined over this special type of finite field and develops Restricted Radix-7 Symmetrical Quaternary Signed Digit (RR7SQSD) modular exponentiation scheme that uses a multiply-by-7 addition/subtraction chain to compute the ...
ABSTRACT The goal of this project was to design a data logging interface using wireless network principle in order to facilitate the process of monitoring physical parameters such as temperature, pressure, humidity, e.tc in the environment. There is a growing desire to find an efficient and cost effective means to monitor these physical parameters, especially at home and industries. The absence of a means to monitor these quantities in an environment has led to so many inadequacies. Th...
ABSTRACT The word “vote” means to choose from a list, to elect or to determine. The main goal of voting (in a scenario involving the students of a given tertiary institution), is to come up with student-leaders of the students’ choice.Most tertiary institutions, FUTO not an exception have problems when it comes to voting. Some of the problems involved include rigging votes during election, insecure or inaccessible polling arena, inexperienced personnel and so on because voting i...
Abstract: The introduction of Non-Transmittable Codewords (NTCs) into Viterbi Algorithm Decoder has emerged as one of the best ways of improving performance of the Viterbi Algorithm Decoder. However, the performance has been tested only in hard decision Viterbi Decoder in telecommunication systems, but not in soft decision Viterbi Decoder and storage media. Most storage media use Reed Solomon (RS) Algorithm Decoder. Yet, the field experience still shows failure of the algorithm in correcting ...
Abstract: This paper presents a survey of recent development in Fault Localisation and Service Restoration (FLSR) following electrical disturbance in Power Distribution Systems (PDS) based on distributed approaches. Distributed approaches have been found to fit well in the distribution systems as they have more than one decisionmaking component, and data processing can be done in parallel in individual units that makes it faster and requires less processing capabilities centrally. Recently re...

ABSTRACT Static analysis can detect a variety of defects and weaknesses in system source codes even before the code is ready to run. Runtime analysis on the other hand, looks at running software to detect problems as these occur, usually through sophisticated instrumentation. Static analysis prevents problems from entering the main code stream and ensures that any new code is up to standard. Static analysis tools can uncover security vulnerabilities, logic errors, implementation defects, and...
ABSTRACT With the growing demand for higher bandwidth multimedia services in a network domain over the past few years, Asynchronous Transfer Mode (ATM) has emerged as a fine solution. ATM provides mobility support for mobile users as they move among base stations. One of the key issues to support user mobility is the handoff. Efficient usage of network resources is also required. Most handover scheme like Mobile Motion Prediction (MMP) Algorithm and Hierarchical Position Prediction Algorithm...
ABSTRACT Communication Protocols are the key tools for data transmission; most of them were defined for asynchronous data transport. Underpinning the Internet is the Internet Protocol (IP), which, has offered an ideal pathway for general Information Technology convergence with its capability of carrying large variety of signals (audio, control, voice, video, data, etc.). This thesis is on “the Design and Simulation of Audio Over IP (AoIP) frequency modulated broadcast studio system”. Us...
ABSTRACT The purpose of this project was to design and develop a Computer Based Testing (CBT) system in order to facilitate the process of conducting e-examinations especially in tertiary institutions. There is a growing need to find an easy and effective way to carryout continuous assessments for the increasing population of students. The CBT system will afford instructors the opportunity to assign different weights to the multiple choice questions. The method adopted was a client/server b...
Abstract Consumers’ complaints of estimated bills from the Utility have risen to an alarming extent in recent years. On the other hand, Utility incurs huge losses attributing it to electric energy consumption theft among consumers. These complaints by the utility and the consumer led to the quest for a system that in addition to recording energy consumption data, will be able to compute and report the data to the Utility remotely. This work proposes the implementation of smart meter which...
ABSTRACT This project work covers the design and construction of a robotic arm mechanically capable of 5 Degrees of Freedom. It solves the problem of automatically detecting and picking up objects placed within distances of 10-30cm round the robot base platform. It does this by using a simplified forward and inverse kinematic relation modeled in two dimensional robot workspace. The work does not cover the more general case, of an n-linked (n>2) robotic arm working within a three dimensional...
ABSTRACT This project presents a 40A maximum power point tracking solar charge controller. The MPPT charge controller tries to keep the voltage and the power stable. The MPPT charge controller will harvest more power from the solar array – it will adjust its input voltage to harvest the maximum power from the solar array and then transform this power to supply the varying voltage requirement of the battery plus load. An MPPT charge controller is an electronic DC to DC converter that optimi...
