Modelling And Optimization Of A Hybrid Energy System For GSM Base Transceiver Station Sites In Emerging Cities

ABSTRACT This study presents the modelling and optimization of a Hybrid Energy System (HES) for GSM Base Transceiver Station (BTS) sites in emerging cities. The aim is to ensure reliable and cost-effective power supply, considering the availability, dynamism and viability of energy sources. Theoretical approach is applied in the modelling, simulation and validation of the developed HES, which consists of the utility grid, wind and solar photovoltaic (PV) as primary energy sources incorporati...

Parametric' Investigation and Classification of Quadratic Equation

Abstract- This study investigated the parameters space of simple and familiar quadratic equation often encounter in science based disciplines and in particular engineering. The aim is strange images creation to excite and launch novices to quest for general understanding of fractal taking parallel clue from Julia and Mandelbrot sets creation using the iterative mechanism of complex quadratic mapping. Preliminary computation of a Julia and Mandelbrot sets was performed on a square complex plan...

Chaotic Secure Communication Schemes employing Chua’s Circuit

Abstract—In recent years, chaotic secure communication systems have attracted significant interest due to their higher unpredictability over conventional secure communications systems and simplicity of implementation. This study presents the modeling of four chaotic modulation techniques. The techniques are Chaotic Masking (CM), Chaos Shift Keying (CSK), Chaos On-Off Keying (COOK), and Differential Chaos Shift Keying (DCSK). Simulations were carried out using Simulink in Matlab environment ...

DESIGN AND CONSTRUCTION OF A 220V VOLTAGE STABILIZER WITH OFF DELAY TIMER..

ABSTRACT Power line fluctuations and cut-offs in electrical installations causes damages to electrical appliances connected to the line. It is may be more fatal in the case of domestic appliances such as fridge and other sophisticated appliances like TV sets, DVD players, computers etc. If a fridge is operated on low voltage, excessive current flows through the motor, which heats up, and get damaged. It can be used to protect the whole installation from undesirable over and under line voltage...

A SMART BREATHALYZER SYSTEM FOR GHANA

ABSTRACT Imagine a five-year-old boy losing his life by being knocked down by a drunk driver who has been intoxicated with alcohol. The driver’s carelessness will cause the family of the little child so much pain, as well as lead to a significant loss of human resources in the country. Road accident according to research has been the second leading cause of death in Ghana. While several countries in the world invest in finding solutions to road accidents [1], little is done by the country t...

Maximum Power Point Tracking of Photovoltaic Systems for Rural Applications

ABSTRACT PV modules exhibit a point at which its power is maximum; this point is called Maximum Power Point (MPP). Due to changes in weather conditions, the MPP changes and the PV module efficiency. Specifically, temperature and irradiance are the parameters that affect the solar panel characteristic properties. This project describes and implements an MPPT algorithm that tracks the MPP at every point in time depending on the load. The algorithm was modeled using MATLAB Simulink and tested un...

A TRACKING AND BILLING SYSTEM FOR COMMERCIAL VEHICLES

Abstract The Ghanaian transit system poses certain challenges to users, as it usually has passengers waiting at bus stops for a bus to their destination, for an unknown amount of time because there is no means of tracking the buses. The system is also problematic as passengers usually argue with bus conductors for change, when payments are made in high denominations, because there are no cashless payment methods available. This makes planning of journeys difficult to users of this system. Exi...

RELIABILITY AND QUALITY ASSURANCE OF ELECTRONIC COMPONENT

ABSTRACT An electronic component is an entity in a system which can not further sub-divided in the course of a given reliability.

CHALLENGES STUDENTS FACE FOR NOT BEING ALLOWED TO USE MOBILE PHONES IN SCHOOL. A CASE STUDY IN TAMALE MOTROPOLIS

ABSTRACT The main objective of the study was to examine the challenges students face for not being allowed to use mobile phone in school with particular reference to Dabokpa Technical Institute in the Tamale Metropolis in the Northern Region of Ghana. The researcher used descriptive research design for the study. The sample size for the study was 185 samples made up of 150 students, 15 teachers, and 10 workshop assistants all from the school and 10 GES personnel from the Regional Directorate,...

DESIGN AND PERFORMANCE EVALUATION OF A BATTERY/SUPERCAPACITOR HYBRID STORAGE SYSTEM FOR RENEWABLE ENERGY APPLICATIONS

ABSTRACT The development of any nation and its economy at large is centred on reliable and efficient power supply. Many developing nations are yet to actualise this feat, and therefore, there is need to strategize to meet the ever-rising demand for energy. Battery-based inverter systems have over the years provided additional power supply to critical loads, in the absence of public power supply. However, high peak charging/discharging power demands results in the degradation of the battery. A...

DESIGN AND OPERATION STRATEGY FOR A GRID-CONNECTED MICRO-GRID SYSTEM

ABSTRACT The economic growth of any country is hinged on reliable and efficient power supply. Many developing countries have not attained sufficiency in energy generation. Hence, there is a need to strategize to meet the ever-rising demand for energy. The micro-grid system can provide a way of escape from this problem as it harnesses the strengths and weaknesses of different energy sources to attain stability in energy provision. The overall aim of this research is the design and operation st...

A STUDY OF POWER FACTOR IMPACT ON ELECTRICAL INSTALLATIONS IN AJAOKUTA STEEL COMPANY LIMITED, NIGERIA

ABSTRACT Power factor is related to power flow in electrical systems and measures how effective an electrical power system is used. In order to efficiently use a power system, the power factor should be as close to unity as possible. This implies that the flow of reactive power should be kept to a minimal. Maintaining a high power factor is crucial to obtaining the best possible economic advantage for both Utilities and Industrial users. Operating a power system at a low power factor is a con...

Analysis of Electrical Surges in Ajaokuta Power System Network, Nigeria

ABSTRACT The study investigates the electrical surge effects and remedy in Ajaokuta Power System Network located in Kogi State in the North Central of Nigeria, to identify various causes of lightning strokes and highlight various associated effects and to determine surge intensity and magnitude, collection of surge data on distribution and transmission network. The approaches adopted is to develop a preliminary data collection that will address the identified data gap and to review comprehens...

Fast Detection of Mobile Phones in the Examination Halls, Classroom and Dormitories of Yeji Senior High Technical School Using GSM Technology

Abstract  This work involves the design and development of a digital signal detector which is capable of detecting incoming and outgoing signals from mobile phones. The presence of an activated mobile phone can be detected by this handy, pocket-size mobile signal detector from a distance of one and a half meters, which could be used in preventing the use of mobile phones in examination halls, classrooms, confidential rooms etc. The circuit can detect the incoming and outgoing calls, tex...
