ABSTRACT. To achieve most accurate coverage area results during installations of sector antennas, the technical team must create a coverage map for each of the sectors basing on the provided coverage values. The technical team uses these values to make manual position adjustments of sector antennas. Manual antenna adjustments are sometimes risky in a way that unexpected accidents usually occur that even result into death. To overcome such scenarios, an android based sector Antenna positioni...
This research was designed to comparatively analyze practical skills acquisition in the Electrical/Electronic Engineering department in Accra and Kumasi Polytechnics. The study population was made of 578 students in the Department of Electrical/Electronic Engineering from the two study institutions respectively. A sample size of 25% was randomly selected from the total population. A total number of 145 questionnaires were distributed and 123 completed questionnaires were received making a res...
The purpose of this paper is to perform path tracking for a non-holonomic mobile robot subject to kinematic disturbances using model prediction and H-2/H-infinitycontrol and by Gain-scheduled control law. In this method, the problem of tracking a mobile robot is expressed in such a someway that its kinematic error is in the form of linear parameter variable with bounded disturbance, the purpose of the design is to stabilize the controller by solving the LMI conditions for the error tracking...

ABSTRACT This project presents the design and construction of a DC to AC inverter system. It is designed to meet up with the power demand in the offices/homes in the absence of power supply from National Supply Authority. It is designed in such a way that it will take up to 12V DC from battery and inverts it to an output of 220V, 50Hz AC. It makes no noise during operation and not hazardous like carbon monoxide is generated to the surrounding. This is the feature makes it safe to used anywh...
Siren is a device that produces loud noise. They are the means communication. Sirens can be seen in emergency vehicles such as police cars, ambulances and fire trucks. Generally, sirens are used as indication or warning. There are different circuits to produce different sirens. The word siren first originated in Greek mythology and was also later used to refer to mermaids. Language and literature have used the word siren as indicative of dangerous temptations. The siren as we understand ...
Despite high levels of good quality tomato production in Kenya, about 40% of the produce goes to waste. This loss is attributed to glut during the harvesting season, poor feeder roads which lead to inaccessibility to the market centres as well as bruise damage during transport. This translates to a huge financial loss to tomato farmers. Preservation through drying technology can help in reducing this loss. Therefore, this study was initiated to investigate the performance of an experi...
ABSTRACT Phase change materials have been widely used in optical and electronic storage due to rapid and reversible phase transition between amorphous and crystalline states with remarkable resistivity and optical contrasts. More recently these materials have been identified as suitable candidates for phase change random access memory (PCRAM) applications due to their potential for high scalability, low power and fast speed operation. Despite these superior properties and enormous potential, ...
Abstract The aim of this project is to investigate and understand the load flow analysis for power systems, during abnormal condition using (Ne plane) with the main focus on load flow analysis theories and computer application. The thesis define the power system security and the effect of load flow , contingency analysis to power system security , and how it effect of equipment of power system network . The thesis investigate Sudan national electricity cooperation during big load period s , ...
Abstract With the growing population rate, the amount of waste being produced is also increasing at a very fast rate. These days in our environment waste management is one of the major problems, the best solution has been proposed to solve this problem is segregating this waste and recycle it. But segregating it manually is complex, dangerous and utilizes more human efforts, cost and time. The proposed system designed to separate five types of wastes into respective bins automatically by the...
ABSTRACT In the last decades, the power industry has had a gradual and steady change from the centralized bulk system (grid) where power is injected to the transmission network from generator to a more decentralized system where power is injected directly to a distribution network (embedded generation). Nigeria is not left out in this trend. In this assessment study, the Siemens’ PSS/E software is used to run the Newton-Raphson load flow program to see the effect of EG on loss reduction and...
ABSTRACT In this thesis, an embedded system which is closely monitored and controlled the climate parameters such as humidity, temperature, and light of a greenhouses based on wireless sensor network on a regular basis round the clock for cultivation of crops or specific plant species which could maximize their production was presented. The designed system comprises beside the sensors from microcontroller, monitor, wireless communication based on XBee and respondents such as fan, heater and ...
Abstract Fuzzy logic is a paradigm for an alternative design methodology, which can be applied in developing both linear and non-linear systems for embedded control. One of successful application that can use fuzzy control is liquid level control. This control system keeps developing from time to time to replace the ordinary system which applies mechanical functions in its control in order to improve the system reliability. In order to find the best design to stabilize the liquid level, the ...
