ABSTRACT The aim of this project, the design and implementation of an RF communication link, is to design a communication link between a source and a destination and study the properties of the signal being generated by the source (generator). The area of interest in this work is how the signal suffers limitations like attenuation, interference and distortion etc and to observe how these limitations affect the smooth transmission of the signal as well as the amplitude of the transmitted signa...
Abstract: This research work seeks to analyze the radio propagation characteristics of a GSM operative network using Makurdi as a case study. The analysis of radio propagation by a GSM operative entails the characteristics/ behavior of the radio wave between the transmitter and the receiver. An understanding of the radio wave propagation characteristics of an environment is a necessary condition for effective radio network planning which translate to the determination of the coverage ...
Research and optimization of cooling of electronic components using heat sinks becomes increasingly important in modern industry. Numerical methods with experimental real world verification are the main tools to evaluate efficiency of heat sinks or heat sink systems. In this research, the physical problems associated with heat removal of electronic systems at different scales were studied. ABSTRACT Research and optimization of cooling of electronic components using heat sinks becomes increa...
Abstract: Series hybrid electric vehicle (HEV) formed by a combination of internal combustion engine and batteries/ultra capacitors in the appropriate ways, provides high-performance and high efficiency power systems for HEV applications. This paper discusses the performance characteristics of series HEV using advanced vehicle simulator. Different sizes of motor and engine were utilized with various battery capacities to explore the optimal component combinations. A comparative simulation was...
Abstract This temperature control fan can be controlled using a microcontroller when it detects a certain temperature that has been set. The purpose of this project is to prevent the waste of voltage usage when it is not hot enough for fan to be needed. The temperature control fan has three different speeds. Each speed will change according to a certain level of temperature that is set. This project is a combination of electric supply, fan, temperature senso...
ABSTRACTThe necessity of a low cost electronic home security system designed in co-ordination with othersecurity measures is always there in our society to reduce the risk of home intrusion. Keepingthis problem in mind, we are working on a project on automatic password based door locksystem. We want to utilize the electronic technology to build an integrated and fully customizedhome security system at a reasonable cost. We hope this project will be useful in keeping thieves,dacoits and other ...
ABSTRACT Whenever we think of redefined security, we think of coded electrical door lock. It is a microcontroller based security door lock that can be used in homes, offices, laboratories, etc. for more reliable and high fidelity door control system, powered by electrons panel or electromechanical panels. Due to high rate of insecurity, especially intrusion into homes and offices, this project provides the users with an electronic keypad to enter the password required to get access into home...
ABSTRACT Cell phones need electric sources to charge their batteries in order to work, but there are people in developing and third world countries that find it hard to access electric sources.In an attempt to provide an alternative means of charging to those unfortunate areas in third world and developing countries, a solar powered cell phone charging booth is to be designed and constructed in this project. The goal of this project is to create a multiple output solar cell phone chargers f...
Abstract In this work, a 2.8kva alternator was coupled to a 4 H.P dc motor acting as a prime mover to produce a fuel-less generator. The coupling was done using two crankshaft pulleys to match the speed of the alternator to that of the dc motor. Two 24v dc deep cycle batteries were also used as the exciter unit and a sustainable output voltage of 232V was achieved.

Abstract Energy is one of the major drivers for the economic development of any country. In order to reduce energy consumptions for sustainable development, continuous energy audit of industrial machines become necessary. Energy audit is one of the most comprehensive methods in achieving energy savings in industry and thus reducing excessive energy consumption. This paper analyzes energy auditing in power system in or...
ABSTRACT Cuckoo search algorithm (CSA) is an effective and highly reliable swarm intelligence basedoptimization approach. It is a technique of determining the most efficient, low cost and reliable operation of a power system by dispatching the available electricity generation resources to supply the load on the system. This paper presents a comprehensive review of CSA application in Economic Load Dispatch (ELD) problem. This review will assist po...
The aim of the project is to design a renewable energy system that can meet the current and projected electricity demands for the island of Great Cumbrae. This should be achieved by providing a stable electricity output and the meet the calculated total annual base load supply of 11.29 GWh. In addition to providing a stable supply of electricity, the environment and social impacts that arise from the project relating to Great Cumbrae should be minimised as well as coinciding with a techn...
Sustainable energy sources have been a topic of interest over a period of time for many researchers. Nuclear energy is one of the sources that have long been exploited for generating heat and electricity both in large scale and small scale. One of the methods for converting this heat into electrical power is using thermoelectric generators. Radioisotope thermoelectric generators are currently the longest-lived sources of energy; it does not require any human maintenance or refuelling. This pa...

Abstract The project DESIGN AND CONSTRUCTION OF A 20-METRE DISTANCE REMOTELY CONTROLLED METAL DETECTOR is used for detecting metallic objects such as phones, bombs, and other metallic objects that are hidden from view. The design is based on the principle of the Resonant Frequency Oscillator (RFO) metal detectors in which oscillation is a function of parallel connection of an inductor and a capacitor operating in resonance. The project is divided into two sections. The transmit...
