Design and Implementation of an Android Based Automatic Sector Antenna Positioning Using Atmega328p. (Case Study: Namuyenje Site in Mokono)

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 posit...

Comparative Analysis of Practical Skills Acquisition in Electrical/Electronic Engineering Training Program in Accra and Kumasi Polytechnics in Ghana.

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 makin...

Mixed H_2/H_∞ and Robust Predictive to Control Wheeled Mobile Robots with Time Delay

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-infinity control 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...

Design and Construction of 2kva Inverter

ABSTRACTThis 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 u...

Design Of An Electronic Siren Circuit

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 sire...

Design, Development And Testing Of A Liquefied Petroleum Gas Powered Tomato Dryer With Water Energy Stotage

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 pe...

Nitrogen Doping Effect On Tin-Selenium Thin Films For Phase Change Memory Applications

ABSTRACTPhase 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, h...

Automation of Waste Segregation Via Sensors by Using PLC

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...

An Assessment Of Embedded Power Generation In Nigeria

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 reducti...

Greenhouse Wireless Monitoring and Control System Based on Sensor Network

ABSTRACTIn this thesis, an embedded system which is closely monitored and controlled theclimate parameters such as humidity, temperature, and light of a greenhousesbased on wireless sensor network on a regular basis round the clock forcultivation of crops or specific plant species which could maximize theirproduction was presented. The designed system comprises beside the sensorsfrom microcontroller, monitor, wireless communication based on XBee andrespondents such as fan, heater and p...

A Comparison between Proportional-Integral-Derivative and Fuzzy Controllers for Water Tank

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 lev...

Reliability Centered Maintenance (Rcm) For Asset Management In Electric Power Distribution System'

ABSTRACTAbility to use electrical energy when required is one of the fundamental presumptions of a modern society, and the introduction of complex and sensitive machines and systems into the network had increased the need for high reliability of supply [1]. Deregulation and competition are forcing improvements in efficiency and reductions in cost while customers are becoming more sensitive to electrical disturbances and are demanding higher levels of service reliability. Since a typical...
