INVESTIGATING THE OPTICAL AND MECHANICAL PROPERTIES OF PHOSPHORESCENT SILICONE RUBBER AS A COMPLEMENTARY SOURCE OF LIGHTING

The household lighting cost accounts for 10% of the electric bill, changing the light bulbs effectively can reduce the long term energy costs significantly. In Nigeria, where less than one percent of the population has access to 24 hours of interrupted power supply there is a need for a complementary, renewable source of light which provides enough illumination at a reasonable price, with assured safety using it and also using for a long duration of time before the need to replace it. Recentl...

Design and Simulation of Telemetry Link and Power System for ABT-18 Unmanned Aerial Vehicle

ABSTRACT The Airbeetle-18 unmanned Aircraft is an Aircraft design for the purpose of surveillance following the fact that the parent Airbeetle-18 has almost reached the end of its life time. Hence, there is need to convert it to an unmanned aircraft in other to extend its service life time. A comprehensive literature review was carried out on Telemetry and power system design and the previous work done as it pertains to aircraft in Airbeetle-18 category. Furthermore, system requirement ana...

Construction of 12V 10A Solar Charge Controller for Solar Energy Utilization

Abstract This project work centered on construction of 12V/10A solar charge controller that is needed in photovoltaic system to safely charge regulate and discharge of sealed lead acid battery through DC load. Solar charge controller is devices that regulate solar photovoltaic power and prevent overcharging, over discharging or overflow of current that reduces the lifespan, durability and performance of the battery. The12v/10A solar charge controller was constructed using variable resistor, ...

Wireless Power Transfer: Design and Implementation of a Wireless Charging Pad

The aim of this project is to shows the possibility of wireless power transfer through the design of a wireless charging pad. In this project write-up, the methodology and principle of operation is wireless power transfer through inductive couple, a feasible design is modelled accordingly. The inductive couple technique is used because it is the easiest method of wireless power transfer with high efficiency and large amount of energy transfer. This report showed the versatility in range of a...

Construction of a 12 Volts DC Fan Controller

Abstract This project work was embarked on the construction and determination of the efficiency of 12 volts DC fan using two N3055 transistor, 1kΩ variable resistors, resistors, breadboard, veroboard, 12 volts DC battery and connectors at Science Laboratory Technological Department, Federal Polytechnic Offa, Nigeria. This is always required to minimize, control or totally eliminate the power fluctuations received at the load end or consumer end that usually lead to the reduction of DC fan li...

THE IMPLEMENTATION OF ADAPTIVE MODULATION IN REDUCING BIT ERROR RATE USING MATLAB AND FUZZY LOGIC MODELLING

ABSTRACT In our present society, wireless communication has become most prevalent and mobile units (hand held devices /GSM/ Computers) are one of the most common equipments for conveying messages wirelessly. Owing to the fact that most youths in our society today on the average make use of at least one wireless device that communicate with other wireless devices via the internet, has made engineers start to think about ways to improve the quality of service (QOS), throughput, spectral effic...

Adequate Power System Planning: A Necessity for an Improved Power System in Nigeria

ABSTRACT-Power system planning is a vast and important issue for operation and expansion of power delivery. One of the basic objectives of planning is to determine the right schedule for investment in new devices which ensures secure and economic power delivery for predicted customer demand. System planning also addresses the question of reliable and stable operation; hence reliability and stability analysis are also included in adequate power system planning studies. This work explores the a...
