ABSTRACT Attention has recently been focused on irregular aspect of the behavior of dynamic systems. One of such behaviour models is chaos which has been widely reported as having a great potential in communications. This study aimed at demonstrating the major concepts in non-linear dynamics and chaos grid the application of these properties in communication. The behavioural modes of logistic map which is a simple dynamical system were investigated with different values of system parameters a...
ABSTRACT The aim of this research was to design a mini-grid solar photovoltaic electricity system for Mpahin village in the Central Region of Ghana. The researcher adopted the mixed method approach. The study is organized into two parts. In the first part of the study, a comprehensive interview was performed on respondents to know their economic conditions, their means of getting light and cooking, their preferred energy, their knowledge about solar energy and its impact on their lives as we...
ABSTRACT In Ghana, Ghana Grid Company, GRIDCo has experienced huge power losses due to poor maintenance and management practices. For this reason persistent power outage has plunged the country‟s economy into a huge set back in the last four years. Power quality problems are common in most commercial, industrial and utility networks. The specific objectives of this thesis were to study the role of automation in improving transmission systems, evaluate maintenance performance in trans...
ABSTRACT Market-driven economies and deregulated electricity industry environments have stimulated minimization of the distribution losses even though they do not constitute major operational or quality of supply problems. This research discusses a method for evaluation of distribution losses and an effective management approach to loss minimization and revenue collection. In this research the contribution of other authors was sought on the distribution losses, their analysis and the va...
ABSTRACT Control of mosquitoes is something of utmost importance in the present day with rising number of mosquito borne illnesses. The effect of mosquito bites cannot be overlooked considering how many deaths it has caused over the years. Specialty products like mosquito repellent used to combat mosquitoes are required but most of the repellants available use chemical means to repel or kill the mosquitoes which in a long run also becomes detrimental to ourselves and the environment. This pr...
ABSTRACT The main purpose of the study was to assess Competency Based Training on the skills acquisition of Electrical/Electronic Engineering Students in Ghana, using Cape Coast Technical University as a case study. The researcher used descriptive research design for the study. The study adopted the mixed approach which made used of both quantitative and qualitative approaches. The study population was made up of all Electrical/Electronic Engineering Students, Lecturers, Laboratory Technicia...
ABSTRACT Most organizations are deploying e-business solutions because of its numerous advantages, such as, increased productivity, reduced transactions costs, wider coverage and increased speed to market. The present academic offices in developing countries still use paper-based approach for most of their activities. Data and information are logged into files, folders and excel sheets which are printed, bound and saved into drawers that are rarely used again for other purposes. In the un...
ABSTRACT This project is the design of an automated expert system (Auto Doc) for medical diagnosis preferably used in remote areas of the society. This AutoDoc is an intelligent system for diagnosing ailments for different patients and prescribes drugs. It has the tendency to advice patients for further medical checkup if need be. The system is gender and age sensitive and it is developed and implemented using VISUAL BASIC.NET. This project is designed and implemented with a group of inte...
Abstract The aim of this work is to characterize properties and microstructure of stainless steel used as a coating on welding of carbon steel sheets. Two carbon steel plates were set as the metal base and the stainless steel coating was applied on the weld bead. The applied process used was the submerged arc welding (SAW) and tests were carried out for the tensile strength and Vickers hardness, in addition to observation of the microstructure by optical microscopy. The results indicated that...
ABSTRACT This project shows the construction of a microcontroller based security door using Smart card. It is aimed towards programming the microcontroller to control the Hardware in sliding door. The system consists of a microcontroller 89S52 which Sends a signal to the multiplexers on insertion of the smart card in the card slot. The multiplexers consist of ICS which prompts for a display of the identity of the Card user in the liquid crystal display (LCD). The LCD displays the status of th...
ABSTRACT Automatic water level controller circuit automatically switches ON and OFF a domestic water pump set depending on the tank water level. This motor driver circuit can be used at home, industry, school or even in agriculture. The approximated cost of the project is very less. The main advantage of this water level controller circuit is that it automatically controls the water pump without any user interaction. The main controller component is a NE 555 IC. We have manipulated the flip f...
Human necessities are increasing day by day where as the factories are running out of resources. To ameet these demands industries need to improve the quality and quantity of their production. Programmable logic controllers (PLCs) have been used for many decades for standard control in industrial and factory environments. Over the years, PLCs have become computational efficient and powerful, and a robust platform with applications beyond the standard control and factory automation. This pa...
Abstract Human existence relies on solar energy either directly or indirectly and the world at large cannot continue to exist, remain or live without the solar energy. Solar power in Nigeria can serve as a source of sustainable energy if fully utilized due to abundant availability all year round energy and its regular appearance on daily basis in the sky under a friendly environment. The maximum output current and power of solar panel used in harvesting solar energy are obtained at sola...
Abstract Solar energy is gaining more attention than ever before due to its potential ability to provide the world energy needed at a sufficient and reliable rate. Putting more focus on its optimum harvesting and utilization can eventually solve the problem of energy shortage by balancing up the energy demand of the nation. Adequate information on the output voltage of the solar panel to cope with the output current during the daytime is essential to be able to predict accurately the esti...
Abstract The current-voltage characteristic is the basic descriptor of photovoltaic device and is used to test the performance of PV panel. The manufacture specifications on solar panels are obtained under standard condition (solar irradiance of 1000 W/m2, AM 1.5 and operating temperature of 25oC) which is not the real operating condition the solar panels are exposed to on the installation site. With this, the information obtained from the manufacture specifications would not be sufficient...
