ABSTRACT Asynchronous Transfer Mode (ATM) of transmission is designed as a Broadband Integrated Services Digital Network (B-ISDN) transfer mode that supports a wide range of traffic classes with diverse flow characteristics. ATM guarantees different quality of service (QoS) demands placed on a network by different services (traffic types). The above powerful feats could be well achieved in ATM network with the application of an efficient and effective network resource management system. This ...
ABSTRACT The line of sight communication between an orbiting LEO satellite and its Ground Station is time constrained by duration of visibility and number of visible passes in a day. In Equatorial region like Nigeria, the average duration is short and number of passes is very few. In most cases, the satellite size is small and therefore power generated on-board is also small, consequently the downlink budget is power constrained. Transmission bandwidth is also constrained by Regulations and n...
ABSTRACT Internet is a huge technology that has brought life to computer and its applications. Most forms of information management and data sharing are done using the internet. The World Wide Web has made this possible. With a browser running on your PC, you can get connected to the entire world. The Internet has been used in different aspects of life most especially in the area of education. Web portal is that area in which the huge resources available on the Internet are being tapped. A we...

ABSTRACT This work modified an existing lead-acid battery charging system by developing and simulating the conventional lead-acid battery and the fuzzy logic control of the lead-acid battery charging systems. The fuzzy logic system is developed using Mamdani inference system in Matlab toolbox and Simulink, and consequently employed in controlling the 12 conventional charging system adopted. The output voltage of the battery is controlled using matrix laboratory (MATLAB) in creating Fuzzy Infe...
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 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 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 This research work designs a wireless power transfer system (WPT) for non smart phones as an alternative to existing wired power supply systems for these devices. Initially, the general concept of known WPT systems and methods are introduced and reviewed. It was noted that most existing WPT models do not consider external interferences in their design even though, it is well known that high frequency circuits may interfere with a WPT system. Additionally till date, existing WPT syste...
ABSTRACT In this current situation, the degree of security is feeble. So there is a lot of robbery, theft going on in and around the world. So, people fear to keep any of their valuables in their homes. Henceforth, many people prefer to keep it in banks. However, in this insecure world even banks are not too safe enough to satisfy people needs. A common man/woman feels his/her valuables are secured if there is efficiency in security. Hence this project can give effective security in minimal c...
ABSTRACTThis report is aimed at explaining the Design and Construction of electronic message display board. It enumerate why we need electronic scrolling message display which is primarily for passage of information across the staff, students and public. It also includes the aim and objectives, advantages and disadvantages with a well narrated literature review and timeline that relates to digital display and its current trends in digital world.Adequate coverage was given to mode of operation...
A modeling with a good predictive rate is necessary to create a good performance of the predictive controller . The correct and better model to use is the Predictive Control Model (MPC) or the Predicted Control Model. This study determines the control optimization system with the Predicted Control Model for the plant of Multi Input Single Output (MISO). The MPC optimal control system designed for the closed-loop Mismatch method, the effect of changes in the Kalman amplifier state estima...
ABSTRACTThe aim of this project is to produce aluminum pots through sand casting process. The cast process involved drawing of element to be cast, making of pattern and core boxes, moulding of pattern, and core boxes, moulding or pattern, moulds assembling, melting of a metal pouring into the mould, solidification and cooling of metal in the mould cast knockout and separation of gate runner and riser, casting surface cleaning, removal of core. This process is use to produce metallic art...
