ABSTRACT Transmission Control Protocol (TCP) is the dominant transport protocol in the Internet and supports many of the most popular Internet applications, such as the World Wide Web (WWW), file transfer and e-mail. The recently developed advanced wireless networks, such as GPRS, are known to cause delay spikes in packet transfer which causes unnecessary TCP retransmission timeouts. In order to find solutions to this effect, packet losses across wireless links should be distinguished from ...
ABSTRACT This project involves the design and implementation of an intelligent obstacle-avoiding robot car. The objective of this project is to implement a robot car, which while moving should have the ability to detect obstacles in its path and change direction where obstacles are present without any form of external influence. The new direction to be taken to avoid collision is the direction that has the most distance between the obstacle and the sensor and this is determined by the robot b...
ABSTRACT A tool for the simulation of stream processing tasks on two dimensional processor arrays is developed in this work. The tool, a Many-core Energy and Latency Estimator (MELE) has provided abstractions from the many design constraints facing application developers on Many-core platforms. A set of models have been designed to improve the programmer’s ability to iteratively map data flow applications to the target machine. Included in the model set are; an application model, which pr...
Abstract Car theft has become prominent all over Ghana in recent years. Despite its growing prominence throughout the country, measures to promptly recover stolen vehicles have often proved tedious and futile. To tackle this problem, this project aims to develop a remote control system and a model of a GPS tracking system which would together help vehicle owners swiftly recover their vehicles should the need arise. This was achieved by developing a mobile application to serve as an interface...
Abstract Vehicles provide an efficient way of transportation across the cities of Greater Accra in Ghana. Technology has impacted the transportation sector through variety of modes such as applications for routing. An example of this is the google maps mobile application. However, due to bad road networks and a time sequenced traffic control system in Ghana, traffic congestion is a major problem during peak times of the day. In cases of emergencies where a route needs to be created for emerg...
Abstract The public transport industry is an essential part of people’s lives. However, the problem associated with the local public transport industry is, travellers usually get frustrated when waiting for a bus to arrive at a bus stop due to uncertainty on when the bus may arrive or if it may arrive at all. This leads to anxiety on the part of the traveller as well as time wastage, especially if this was not planned for in the trip. To solve this, historically GPS receivers are used in co...
Abstract Streetlights are public goods that beautify cities, ensure safety for road users and security for city neighborhoods. A delay in streetlight maintenance jeopardizes the safety and security of many. Also, when streetlights stay on throughout the day, it wastes power and energy and increases cost. This project presents the design of a low-cost streetlight monitoring system based on LoRa technology. In the design, a Dragino LoraWAN 868MHz (LoRa/GSM) gateway module was used alongside one...
Abstract The issue of vehicle accidents occurring on the roads on a daily basis, which only seems to be increased by the minute is what this paper researches and seeks to tackle. With the simple technology that has been made available globally, a cost-effective system can be developed to fight overspeeding, reduce road accidents and save lives. As a result, in this project, an Automatic Number Plate Recognition program and a web service for speed detection were implemented. This was done with...
Abstract This research presents a conceptual procedure for characterizing the essential nature of the diagnostic reasoning process. This computerization of the medical neurological section of the University College Hospital Ibadan in Nigeria leads to effectiveness and efficiency of the existing medical diagnosing process. The main purpose of this project is to design a computerized brain diagnosing system that would be used in carrying out the daily diagnosing activity in the clinic. The dev...
ABSTRACT This thesis work seeks to complement ongoing research works on heat transfer from heated surface to supercritical water in the SCWR. The study was inspired by ongoing efforts directed at obtaining a correlation that predict supercritical-water heat transfer more accurately, especially with the identification of the SCWR concept as one of the six Generation IV nuclear reactors. The thesis focuses on the development of an improved heat transfer correlation for supercritical water flowi...
Abstract Detection and Prevention of Man-In-The-Middle Spoofing Attacks in MANETs Using Predictive Techniques in Artificial Neural Networks (ANN) A Mobile Ad-Hoc Network (MANET) is a convenient wireless infrastructure which presents many advantages in network settings. There are however a lot of challenges faced on such networks; with their relatively much more flexible setups. They are comparatively more susceptible to attacks of various kinds as opposed to their wired cousins. This is due t...
ABSTRACT The One Laptop Per Child project has succeeded in developing a novel computer that is tailored to the particular needs of the developing world. The use of this example of a modern computer systems design challenge can be a valuable case study as a teaching tool in computer science. The OLPC laptop is a multiple-purpose computer that is rugged, low-cost, low-power, mesh networked, and inexpensive. An overview of the technology in the laptops is given, as well as curricula suggestions ...
Abstract The project proposed a method of reading individual energy consumption by tenants living in a compound house but share a single meter. The smart energy monitor was designed using ATmega8, SIM800l, PZEM004T, I2C LCD ,SCT-013-000 current sensor. The smart energy monitor solves the problem of bill sharing in compound house that share one meter. The printed circuit board was design ed using Eagle and the program for the system was programmed in the Arduino IDE in c language in Arduino sy...
Abstract Accessing remote health care from public hospitals in Ghana has become more difficult and expensive recently due to the increasing number of patients that surpass the low number of doctors in the country. Many people have lost their lives waiting in long vital checking lines just to take their vitals in some hospitals. However, with the help of the Internet of Things (IoT), this report provides a design of a low-cost remote health monitoring system for patients with chronic diseases ...
ABSTRACT This paper explores the current flaws of the undergraduate syllabi treating Industrial Automation and Control. It elaborates on the disparities between the current syllabi and what is used in Industry; particularly the current trend of Industrial Automation. It looks at the effect of not meeting this trend in Industry and thus offers a solution in the form of another curriculum, which incorporates concepts of Industrial Automation 4.0 which are necessary for the workplace. It uses th...
