Abstract A wireless signal jammer is a device which blocks transmission by creating interference. This wireless signal jammer can be categorized into the Radio Frequency (RF) jammer and GSM jammer. A Radio Frequency jammer is a device used to disrupt or prevent communication via a broadcasted RF signal. It is an RF and GSM frequency disrupter... Continue Reading
ABSTRACT The practical importance of a battery charger in today world cannot be over emphasized. This is so as those batteries accumulators are immensely needed by out auto mobile and in science laboratories. This thesis describes the methodical approach to the design and construction of any battery charger. However the procedure fro developed... Continue Reading
Adding to the requirement and need for power supply for day to day activities, it is therefore a necessity to design the power system to maintain minimal technical losses in the network, because most of our system component lack sufficient reactive power ability, this mean that the penetration of distributed generation (DG) will give way to reduce...

ABSTRACT Waste and residuals are undeniably part of the human society. The accumulation of these materials and the “throw away” philosophy results in many environmental and health issues and safety hazard problems prevent sustainable development in terms of resource recovery and recycling of waste materials. The carbon sources in the waste can... Continue Reading
Abstract Heart beat rate means the number of heartbeats per unit time, usually expressed as beats per minute (bpm). The human heart pounds to pump oxygen rich blood to the muscles and carry cell waste products away from the tissues. Heartbeat rate can vary according to the demand of the muscles to absorb oxygen and excrete carbon dioxide changes... Continue Reading
ABSTRACT Audio loudspeaker (output transducer) is on of the most essential and powerful device used in telecommunication system. This is device capable of converting electrical signal into sound and vice versa. It is made up of few time of non-magnetic wire wound on a light cylindrical former that is mounted so that it can move freely insides the... Continue Reading
ABSTRACT Researchable lamp is a source of light that is generated from a D.C sources of supply this D.C sources is a battery that can also way be charged when it current and voltage ruse I decided to work on this as my project because its importance. It is very portable and help the a lot during night reading It also serves as an immanency sources... Continue Reading
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... Continue Reading
ABSTRACT This project presents the design and construction of a DC to AC inverter system. It is designed to meet up with the power demand in the offices/homes in the absence of power supply from National Supply Authority. It is designed in such a way that it will take up to 12V DC from battery and inverts it to an output of 220V, 50Hz AC. It... Continue Reading
ABSTRACT In recent years the entire world is a warring about energy resources limitation, specifically Sudan country confronts critical crises in fossil fuel resources and yet more of electricity energy producing from fired thermal power plants. One from these plants Garri”2” combined cycle producing about 180MW. Exergy analysis in the light... Continue Reading
ABSTRACT Condition monitoring of Electrical power equipment has attracted considerable attention for years. The aim of this work is to use Fuzzy logic (FL) Tool Box in building a simulation system that will diagnose all kinds of incipient faults, phase to phase fault and overloading in a transformer and monitor its conditions. Current and rate of... Continue Reading
ABSTRACT Power inverter is an electrical appliance that can be used with DC battery as an alternativesource of energy supply in the event of power failures and energy crisis. It is cheap, clean,very conducive and silent when in operation and a very reliable source of power supply as togenerator. Modern research and technologies have shown that... Continue Reading
Siren is a device that produces loud noise. They are the means communication. Sirens can be seen in emergency vehicles such as police cars, ambulances and fire trucks. Generally, sirens are used as indication or warning. There are different circuits to produce different sirens. The word siren first originated in Greek mythology and was also... Continue Reading
ABSTRACT The 200W solar system was determined by load assessment, solar panel number determination, battery requirement and then inverter sizing. A complete solar panel rated at 200w was however purchased, together with 2 no. 150A solar battery, 1500W inverter and also 10A charge controller. These were assembled together with necessary protective... Continue Reading
Anatomical variation in the human body presents a complex challenge to design a universal antenna for all. The presence of the human body in close proximity to the antenna also presents a challenge as the near field strongly couples with a lossy medium. Other challenges include design of an antenna that is small in size without affecting its... Continue Reading
CHAPTER ONE INTRODUCTION 1.1Background Information Electricity is a general term comprising of a variety of phenomena resulting from the presence and flow of electric charge. These include many phenomena, such as lightning, static... Continue Reading
ABSTRACT This project the design an construction of fire alarm was carried out with deep intensive and extensive research work my aim and objective in the price of work is to produce a standard device or electronics that will inform the security about a fire outbreak in the company or house for a quick reaction/action. In this project I shade... Continue Reading
ABSTRACT This research work on “Modelling and Simulation of Leakage-Induced Pressure drops along oil and gas pipelines tends to develop flow equations that can detect and localize leakages in oil and gas pipelines by modifying the Darcy-weisbach equation for liquid/oil flow, and the Panhandle B equation for natural gas flow in pipelines. These... Continue Reading
ABSTRACT As the demand of energy is increasing day by day, so the ultimate solution to deal with these sorts of problems is just to implement the renewable sources of energy Humans are using the renewable energy which are solar, wind etc. but we still could not satisfy our power needs, because of that we have to generate electricity through each...
