ABSTRACT Interior Permanent Magnet (IPM) motor is widely used for many industrial applications and has relatively high torque ripple generated by reluctance torque. Since the configuration of the stator has great influence on reluctance torque, different stator configuration is necessary to improve the torque performance of IPM motor. Natural variable modeling and performance comparison of Interior Permanent Magnet Motor with Concentrated winding (CW), Short pitched and Full pitched distribut...
Abstract A batch type direct passive solar dryer was designed and fabricated to dry salted tilapia fish fillets. The dryer has a capacity a capacity of 1500g/batch. The tilapia fish species were obtained from Domita Farms Nig. Ltd,.Uyo, Akwa Ibom State and transported immediately to Nsukka in a cold storage container. The salted fish fillet was prepared to conform to thin layer drying specification of 3.0mm-5.0mm thickness before drying. The solar drying experiments were conducted at the Depa...
ABSTRACT This thesis is a study of short-term electric power forecasting in the Nigerian power system using artificial neural network model. The model is created in the form of a simulation program written with MATLAB tool. The model, a multilayer timedelayed feed-forward artificial neural network trained with error back propagation algorithm, was made to study the pre-historical load pattern of a typical Nigerian power system in a supervised training manner. After presenting the model with a...
ABSTRACT As the prices of building materials in the country continue to increase sharply, there is growing need to source local materials as alternative for farm building constructions. This project investigates the performance of a cylindrical shell built of laterized concrete for storage of foodgrains or water. L In order to optimize the mix ratio of the constituent materials that will produce maximum strength, a mathematical model which relates the strength of laterized concrete and its co...
ABSTRACT A single line contingency analysis and generator(s) outages were carried out on 330kV, 27-Bus power network using MATPOWER 4.1 embedded in MATLAB to carry out fast decoupled load flow studies in order to identify the voltage violation at various buses, determine power losses at the transmission lines and to compute the performance indices. The performance indices were further ranked in accordance with their severity index. Voltages less than 0.95pu were assumed to be low voltages and...
ABSTRACT This project presents a quality model of induction motor showing steady state and dynamic analysis using Volt/Hertz open loop, Volt/Hertz closed loop, Slip differences and constant flux methods. The main objective is to maintain the speed at constant rotor flux and to investigate the control schemes for controlling induction machine, particularly the scalar control method and to evaluate their performance under variable input-output conditions. Analysis of the steady state equivalent...

ABSTRACT: Presentation slides for the course project on the topic Graphene-based surface plasmon polariton for plasmonic waveguides and devices. Throughout the project the used of FDTD simulations were conducted for the report.
ABSTRACT: The inconsistency present in Transmission line tends to have a cascading collapse and different types of failures in the transmission line of a power system which impact the power transfer capability of the line. In this paper we used MATLAB coding to plot the real power and reactive power with voltage. We want to predict what happens to the stability of a power system before a cascading collapse. Note: The MATLAB code was intentionally added to this work to serve as a base for...
ABSTRACT: Hemoglobin concentration sensors are created in this study using a row of half-cylindrical rods. The suggested structures are capable of accurately detecting blood sample hemoglobin concentration. Two different topologies based on graphene-plasmonic couples are proposed and explored and a comprehensive review is included in this work. The proposed structures are composed of layers of graphene SiO2, Au, and Ag. Multiple plates and cylindrical-shaped graphene layers are added to the ...
ABSTRACT Nina Interiors is a leader in the furnishing industiy which aims at developing the use of Information and Communication Technologies (ICT). One of their major avenues where ICT is used is to share and disseminate information in their website about their products. Organizations that have put to use ICT tools are able to sell buy and market their services online which is enabled by their use of dynamic websites. However this is not the case with Nina Interiors. The existing website is ...

The study used a lot of methods to make the whole research process effective. It employed both exploratory and descriptive research designs to draw explanations as to why Fibre Optic Technology was being adopted in Uganda. Data was collected from both primary and ...
Musculoskeletal pains (MP) especially the lower back, leg, neck and shoulder pain were the common complain among the classroom teachers due to prolong desk working and standing in the classroom. The study was conducted among the primary and secondary school classroom teachers in randomly selected two hundred and seven (207) schools in Egba division of Ogun State, Nigeria.
ABSTRACT The purpose of this study was to implement an effective Computerized Web-Based Information System (CWIS) that help electrical network losses computation in order to monitor the performance of the electrical network over time, to guide managers in making decisions for corrective and preventive maintenance in the existing electrical distribution network where technical and nontechnical losses were not accurately known. The apparent power, real power, unbalanced power in phases, power...
