DESIGN AND CONSTRUCTION OF ELECTRICAL CODED DOOR LOCK SYSTEM

ABSTRACTWhenever 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 ...

DESIGN AND CONSTRUCTION OF A SOLAR POWERED MULTIPLE CELL PHONES CHARGING BOOTH

ABSTRACTCell 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...

CONSTRUCTION OF A 2.8KVA FUEL-LESS GENERATOR

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.   TABLE OF CONTENTSTitle PageDeclarationCertification. iiiDedication. ivAcknowledgement. vTable Of Contents. viLis...

Analysis of Energy Auditing in Nigerian Power Systems

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  audi...

Cuckoo Search Algorithm Optimization Approaches for Solving Economic Load Dispatch: A Review

ABSTRACT  Cuckoo  search  algorithm  (CSA)  is  an  effective  and  highly  reliable  swarm  intelligence  based optimization  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 (EL...

Wind Power and Solar PV renewable energy generation on an Island of Great Cumbrae

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 coi...

RADIOISOTOPE THERMOELECTRIC POWER GENERATION

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...

Design and Construction of a 20-m Distance Remotely Controlled Metal Detector Using Arduino

   AbstractThe 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 ...

Carrier Transport and Recombination In A-SI: H PIN Solar Cells in Dark and Under Illumination

Abstract A study has been carried out on the forward bias dark current and the short circuit current-open circuit voltage characteristics of a-Si: H pin solar cells over wide range of illumination intensities. Results are presented with superposition of these characteristics over extended current voltage regimes. This and the observed separation between these characteristics are consistent with the arguments presented based on first principle arguments.

Optimization of open circuit voltage in amorphous silicon solar cells with mixed-phase (amorphous+nanocrystalline) p-type contacts of low nanocrystalline content

Both the origins of the high open circuit voltages (VOC) in amorphous silicon solar cells having p layers prepared with very high hydrogen dilution and the physical structure of these optimum p layers remain poorly understood topics, with several studies offering conflicting views. This work attempts to overcome the limitations of previous studies by combining insights available from electronic measurements, real time spectroscopic ellipsometry, atomic force microscopy, and both high-resoluti...
