ABSTRACT In this work, an expert system for energy management in community based microgrid was developed. This was necessitated in a bid to address the inadequate power supply predominant in sub-Saharan African countries, while also addressing the problem of energy wastage that comes from individuals supplying their own energy demands. To achieve this, an architecture for a microgrid network was developed by adopting existing standards in the geographical region of interest. An energy manage...
ABSTRACT This thesis examines the development of a gas propellant rocket motor using cheap local materials. The fabrication of the prototype rocket engine was achieved by using machine tools like the lathe and drilling machines. The internal radius around the nozzle throat area was made without using any special tools for curves. The engine was tested twice and readings or data taken for pressure and temperature. Two thermocouples were damaged because the temperature exceeded their temperatu...
ABSTRACT The development of a Cathodic Protection System for a mild steel pipe using a magnesium anode was investigated. The pipe was externally coated with three layers of polykene tape wrapping and the soil resistivity was determined using the Wenner four pin method; a value of 2177Ωcm was obtained. The design parameters for the developed Cathodic Protection System were: total current of 0.0153mA; current density of 0.01mA/m 2 ; protection current of 0.0153mA; protection voltage of 0.95V...
ABSTRACT A non-weighing lysimeter was designed, fabricated, tested and installed at Arochukwu, Abia State, Nigeria, where the farmers who engage in dry season vegetable production do so with no knowledge of irrigation water requirements. This method tends to either over-irrigation or under-irrigation below the vegetable water requirements. Too much water can leach costly fertilizers to depths below the root zone, where both the water and fertilizer are permanently lost. Too little water caus...
ABSTRACT In this work, the operation and performance of a novel Separation Tray Column under Vertical and Tilt conditions is presented. The Tray Column used for the work is a Downcomerless liquid initiated and controlled Valve Tray with capacity to shut portions of the tray lacking liquid at any time. To evaluate the mass transfer performance of this column, an oxidation experiment was conducted at 300C and the percentage of Fe (II) oxidised to Fe (III) from contaminated water by air was cho...
ABSTRACT A direct-heated solar crop dryer suitable for rural farmers and households was developed and evaluated. The simple structured dryer was fabricated using square and round pipes, aluminium sheet, Perspex, wire gauze, bolts and nuts. Its performance was evaluated using cassava chips and three cylindrical aluminium chimneys of heights 1200mm, 800mm and 400mm; all of equal diameter. Mature cassava roots were peeled, washed, chopped into flat circular chips of 10mm thickness and spread on...
ABSTRACT Suitable rainfall models of Enugu City is presented based on the statistical method of least squares. A total of 23 rainfall models are developed in all and grouped into 2 sets. The first set contains 4 rainfall models which represents an inverse relationship between rainfall intensities and durations for specified return periods of 1.1, 2.2, 5.5 and 11 years. High and positive values of coefficients of correlations of 0.9735 to 0.9885 were obtained; an indication of good curve fitt...
ABSTRACT This thesis describes the in situ methods of the determination of both the hydraulic conductivity and infiltration capacity of the Federal University of Technology, Owerri (FUTO) farm soil. The inverse anger hole method was chosen to determine the hydraulic conductivity due to its simplicity and effectiveness. Cognizance was taken of the factors as presented in the project report that affect the results determined. Also the various methods of determining the two parameters were revi...
ABSTRACT This study is on the determination of the Compressive Strength of Palm Kernel Shell Concrete. The effect of percentage replacements (0, 25, 50, 75 and 100%) of crushed granite with palm kernel shell on density and compressive strength of concrete is presented. Concrete cube specimens of mix 1:2:4 were prepared with water-cement ratio of 0.6. The cubes (150mm×150mm×150mm) were cured using water-submerged curing until testing ages of 7, 14, 21 and 28 days when their densities and co...
ABSTRACT In this research, Social Network Web Application (SNWA) was developed and tailored for a specific use; community development in the Niger Delta region of Nigeria. In the SNWA development, preliminary context analysis was conducted to capture contextual information on community development challenges in the Niger Delta and the readiness of the target local community to adopt web-based solution to the identified challenges. Subsequently, User-Centered Requirement Engineering, User-Cen...
Abstract Design of a Robust Electronic Internal Temperature Controller for Petroleum Distillation is presented in this Thesis. During unstable weather conditions, there is a noticeable drop in the distillation internal column temperature. An extreme and frustrating case of this occurs during rainfall and at night when the fractional distillation column external temperature drops, greatly affecting the internal. Consequently, it becomes difficult to maintain a stable and optimum internal temp...
ABSTRACT Communication Protocols are the key tools for data transmission; most of them were defined for asynchronous data transport. Underpinning the Internet is the Internet Protocol (IP), which, has offered an ideal pathway for general Information Technology convergence with its capability of carrying large variety of signals (audio, control, voice, video, data, etc.). This thesis is on “the Design and Simulation of Audio Over IP (AoIP) frequency modulated broadcast studio system”. Usi...
Abstract The design, construction and performance test of a parabolic solar cooker for domestic use are presented. The simple experimental parabolic solar cooker, made of locally available materials, consists of a parabolic dish of thickness 0.3mm, adjustable mechanism, pot, pot holder, base support and a reflecting glass surface. The concave surface of the dish was lagged with reflective glasses which serve as a reflecting surface. Commercially available (3mm) thick glass is used as glazing...
ABSTRACT In this project work, a hybrid cloud system using StackOps Distro Community Edition was designed and implemented. The Electrical and Electronic Engineering Department of the Federal University of Technology, Owerri was used as a case study. This is essential as there is greater need for readily available and on-the-go Information and Communication Technology services. Ubiquitous access to data, files, documents, project work and the like are vital in all spheres of life, and especia...
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 system will afford instructors the opportunity to assign different weights to the multiple choice questions. The method adopted was a client/server ba...
