ABSTRACT The basic idea deals with detecting the voltage collapse ahead of time to provide the operators a lead time for remedial actions and for possible prevention of blackouts. To detect cases of voltage collapse, pattern recognition in conjunction with power system simulator for engineering (PSSE) program was created and then deployed in Nigeria 330KV integrated power system to develop Regularized Least Squares Classification (RLSC) as well as Classification and Regression Trees (...
ABSTRACT This paper presents the operation of centrifugal pumps as turbines for micro hydropower application. Block diagrams are used to present components required from intake chamber to hydropower plant and their electrical energy mechanism for micro hydropower system. A comparison of operational parameters of pump as turbine and conventional turbines is discussed. Also, the paper discusses three types of methods for selecting the centrifugal pump as turbine based on the head, flow rate, r...
ABSTRACT The goal of this project was to design a data logging interface using wireless network principle in order to facilitate the process of monitoring physical parameters such as temperature, pressure, humidity, e.tc in the environment. There is a growing desire to find an efficient and cost effective means to monitor these physical parameters, especially at home and industries. The absence of a means to monitor these quantities in an environment has led to so many inadequacies. Th...
ABSTRACT The word “vote” means to choose from a list, to elect or to determine. The main goal of voting (in a scenario involving the students of a given tertiary institution), is to come up with student-leaders of the students’ choice.Most tertiary institutions, FUTO not an exception have problems when it comes to voting. Some of the problems involved include rigging votes during election, insecure or inaccessible polling arena, inexperienced personnel and so on because voting i...
ABSTRACT In the present work, STAR-CCM+ CFD code was used to investigate steady state thermal hydraulic parameters in the core of Ghana Research Reactor-1 (GHARR-1). The core was segmented into 21 axial segments. 3D-CAD parametric solid modeler embedded in STARCCM+ was used to model the geometry. The geometry was discretized by the use of appropriate meshing models. GHARR-1 operating conditions were set as boundary conditions for the STAR-CCM+ simulation conducted. Heat flux specific to indi...
Abstract The study was carried out to identify the entrepreneurial skills required by Internally Displaced Persons (IDPs) in quail production for sustainable living in North-Central Nigeria. Specifically, the study identified skills in planning, rearing and marketing of quail and its products in the area of study. To achieve these specific objectives, three research questions and three null hypotheses were formulated to guide the study. The study adopted descriptive survey research design. T...
ABSTRACT This work was designed to determine the ways of enhancing food production through organic agriculture among farmers. Five research questions and five null hypotheses guided the study. A survey research design was adopted for the study.The study was carried out in northern zone of Cross River State, Nigeria. The population for the study was 230 comprising 205 registered crop farmers and 25 Agricultural Development Programme (ADP) extension agents from Ogoja Agricultural Zone respecti...
Abstract The study was carried out to determine the effects of Moringa oleifera leaf powder additive on the growth of layers, egg production and nutritive value of eggs. Specifically, the study sought to determine among others the effects of Moringa oleifera leaf powder fortified feeds and control feed on the growth of layers, effects of different inclusion rates of Moringa oleifera leaf powder on the growth of layers, effects of Moringa oleifera leaf powder fortified feeds and control feed ...
ABSTRACT The study was carried out to determine the effect of suggestopedia instructional technique on academic achievement, interest and retention of metalwork students of technical colleges. Six research questions were answered while nine null hypotheses formulated were tested at a 0.05 level of significance. The study adopted a quasi-experimental design and was carried out in Lagos State. The population for the study was 410 male and female students. The sample size for the study was 114 ...
Abstract The study was carried out to develop a training programme in cocoyam production for enhancing job opportunities of youth in South Eastern Nigeria. The study adopted research and development (R & D) design. The study was carried out in the South-East states of Nigeria, namely Abia, Anambra, Ebonyi, Enugu and Imo states. The population of the study was 5075 made up 21 lecturers, 292 extension agents and 4510 registered cocoyam farmers all from South-East Nigeria. The sample for the st...
ABSTRACT A biofiltration wastewater treatment pond was developed and the performance evaluation undertaken at the Department of Agricultural and Bioresources Engineering, University of Nigeria, Nsukka, southeast, Nigeria. The biofiltration wastewater treatment system is made of three compartments comprising a wastewater storage unit, wastewater treatment unit and treated wastewater compartment. The compartments are of the same size with the following dimensions 0.61m x0.61m x 0.5m having a ...
ABSTRACT In this research work, Bioremediation technology was used to reduce the heavy contents of the soil collected from the bank of the sewage pond of the University of Nigeria Nsukka. The heavy metals were; zinc (Zn) cadmium (Cd) and lead (Pd). In the bioremediation process, fungi, bacteria and plants were used. The bacteria used were Bacillus cereus, the fungi used was Aspergillus fumigatus and the plant used was Bryophyllum pinnatum (life plant). The combinations of these organisms wer...
ABSTRACT With the growing demand for higher bandwidth multimedia services in a network domain over the past few years, Asynchronous Transfer Mode (ATM) has emerged as a fine solution. ATM provides mobility support for mobile users as they move among base stations. One of the key issues to support user mobility is the handoff. Efficient usage of network resources is also required. Most handover scheme like Mobile Motion Prediction (MMP) Algorithm and Hierarchical Position Prediction Algorithm...
Abstract This thesis aims to extract d-axis machine parameters of a 214 MVA high-speed turbogenerator using well-established offline techniques. MATLAB/SIMULINK tool has been utilized to model the generator and perform sudden short-circuit (SSC) tests. Because constant speed operation of the generator is vital consideration for the accuracy of SSC tests for parameter extraction, this thesis has employed an arrangement of 2 DC motors operating alongside a drive system, which is configured to ...
ABSTRACT The development and utilization of energy has led to environmental degradation with associated health hazard. Hence the trust of this project is to optimize energy mix in a reliable, affordable, available, safe, efficient, effective and sustainable way at control cost subject to environmental constraints. In other to achieve the desired goal, the optimization model is derived with unit cost of each of the various energy sources as the objective function and environmental impact as c...
