ABSTRACT Spatial qualification problem, an aspect of spatial reasoning, is concerned with the impossibility of knowing an agent‟s presence at a specific location and time. An agent‟s location determines its ability to carry out an action given its known spatial antecedents. There are sparse works on the formalisation of this problem. Qualitative reasoning approach is the most widely used approach for spatial reasoning due to its ability to reason with incomplete knowledge or reduced data...
Abstract The postharvest losses in fruits and vegetables in developing countries vary between 15-90%. Many organizations are actively promoting the processing of fruits and vegetables to find a solution to the difficulties encountered in storing large quantities of fresh produce without incurring heavy losses. This study evaluated the chemical, microbiological and sensory properties of leather blends produced from 'Ogbomoso' mango and carrot. Purees of mango (Mangifera indica 'Ogbomoso') and...
Abstract Nonlinear parabolic interface problems are frequently encountered in the modelling of physical processes which involved two or more materials with different properties. Research had focused largely on solving linear parabolic interface problems with the use of Finite Element Method (FEM). However, Spectral Element Method (SEM) for approximating nonlinear parabolic interface problems is scarce in literature. This work was therefore designed to give a theoretical framework for the con...
ABSTRACT Background & objectives: The challenge of malaria and efforts targeted at developing malaria vaccines triggered this study on the reactivity of IgG and its subclasses in the test serum specific to CSP. This work was directed at assessing the influence of age and gender on host humoral antibody against Plasmodium falciparum recombinant circumsporozoite antigen in Nigerian children. Methods: In all, 67 serum samples (>10,000 parasites/μl of blood) collected from malaria-infected chi...
ABSTRACT This study examined the contribution of value addition in agriculture to socio-economic development with reference to the oil palm industry in Kwaebibirem District. The specific objectives addressed in this study were to: determine the character of the activities that generate value in the oil palm industry; find how the process of value addition contributes to development, especially in terms of employment and income; and analyse the wider policy implications for agricultural devel...
Abstract The study was undertaken in the Afadjato Community Forest Conservation Area between August 2010 and June 2011 with the following objectives: 1. To document and analyse the diversity of plants in the Afadjato Community Forest Conservation Area. 2. To undertake a quantitative ethnobotanical study of traditional knowledge and plant use among local people living in the study area. 3. To explore the relationship between plant diversity and use; and 4. To determine the conservation and ec...
Abstract As a middle income country, Ghana has made formidable strides in improving health care delivery in the country. Notable among them is the introduction of the Community Health and Planning Services system. This system was adopted to increase access to and use of health care services by setting up health centers known us CHPS zones in the remote communities where it is particularly difficult for Ghanaians to receive proper and timely medical attention. These health centers are manned b...
ABSTRACT Inventory management is key in every business setting. Proper inventory management helps businesses to reduce cost and maximize profit. Hence, this project seeks to design and build a user-friendly inventory management system that will work on a web platform to allow the staff of Dzigua Enterprise in Accra to key in inventory details for their various agricultural products. The staff should be able to key in inventory received and removed either for processing or sales to allow for t...
Abstract Examination writing in Ghana seems to be a location based process. This is so because most examinations taken, be it school exams or other external examinations, are taken at specific selected locations. If exams are to be taken in a school like Ashesi University for instance, there is a time table drawn which includes a course, date, time and place of the exam. The processes that precede it include typing and photocopying of questions which can use up a lot of paper, time and space ...
Abstract Ashesi University College recently acquired a TurtleBot1 robotic platform to experiment with service robotics on campus. This platform runs the Robotics Operating System (ROS)2 for developing robotics applications. This MOLAM project (Motion, Localization And Mapping) sought to build a fundamental framework that extends ROS functionalities on a TurtleBot to navigate autonomously around the Ashesi campus in Berekuso. The focus of this project was to extend the ROS enabled functionalit...
Abstract Automated machine learning holds a lot of promise to revolutionize and democratize the field of artificial intelligence. Neural architecture search is one of the main components of AutoML and is usually very computationally expensive. Autokeras is a framework that proposes a Bayesian optimization approach to neural architecture search in order to make it more efficient [8]. AutoKeras suffers from two major limitations: (i) the lack of support for parallel Bayesian optimization, which...
ABSTRACT Computer Role-Playing Games (CRPG) are a genre of video games were the player controls at least one character, the character has attributes and relationships with other game objects and is important to the story. They are one of many entertainment media that have storytelling as one of its major components. The better the story component of a game the better the gameplay experience is. This project explores an approach to improving gameplay of RPG games by personalization of game sto...
Abstract In today’s world, the notion that knowledge has become the most vital resource in the transformational growth of societies is one that is pervasive. The significance of knowledge in modern societies has been overemphasized by several international bodies; most notable the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the World Bank. Ghana's desire to craft an economy where knowledge and information would play a significant role is visible on paper in...
Abstract This paper evaluates the performance of the Particle Swarm Optimization (PSO) scheme, a genetic algorithm, as used in Medium Access Control (MAC) protocols for Wireless Sensor Networks (WSNs). In doing so, the protocol is implemented and compared to round-robin, a contention-free protocol that makes sensor nodes take turns in sending their data packet to the sink, and a p-persistent CSMA protocol with a p-value of 0.01. The concept of p-persistence as used in the CSMA protocol is emp...
ABSTRACT Optimization techniques are called into play everyday in decision making processes involving resource allocation in almost every discipline. However, the development and implementation of algorithm for solving optimization problems are fraught with many difficulties and frustrations. The aim of this thesis has been to examine and identify some of the problems associated with the development and implementation of a class of optimization algorithms and to develop a means of improving ...
