ABSTRACT This study demonstrated the application of Markov S-I-R model and other statistical methods in exploring HIV, Tuberculosis (TB) and Hepatitis B (HB)disease outcomes using Ghanaian data. Secondary datasets from cohort studies were collected from records from the Ashanti Regional Hospital. Relevant disease metrics as well as transition probabilities were generalized for each disease. Method of Competing risks was used to further estimate the crude, partial crude and net probabilities o...
ABSTRACT Traditionally, bus ticket purchase has been over the counter in bus terminals, however, today it has evolved with the rapid expansion of e-commerce. This project addresses the study and development of an Online Bus Ticketing System web portal that enable customers (passengers) and the staff to make an online bus ticket sale/purchase, ticket cancel, ticket postponement, driver rating, generating of reports and etc. which also act as an operation tool for bus ticketing companies to ope...
ABSTRACT The post harvest management of pineapple quality is a problem that many Ghanaian pineapple exporters are grappling with. Importers pay premium only on top quality fruits that satisfy market and consumer expectation. An effective Quality Management Approach (QMA) which takes into consideration market demands and consumer expectation would be the key to making Ghanaian exports competitive on the world pineapple trade. In this study, glazing or surface coating of pineapple was employed ...
Abstract Dracunculiasis still remains as a disease o f public health importance in Ghana, especially in the Northern, Volta and Brong-Ahafo Regions, despite over a decade o f an Eradication Programme. In this study, attempts have been made to determine the problems associated with the eradication o f Guinea worm in the Northern Region o f Ghana, and suggestions provided to overcome them. Also investigated were the longitudinal anatomical variation of the parasite, the vector species and ...
ABSTRACT A problem of the ratio-type estimators in Stratified Sampling is the use of non-attribute auxiliary information. In this study, some ratio-type estimators in stratified random sampling using attribute as auxiliary information are proposed. The sample mean of study variable and proportion of auxiliary attribute were transformed linearly and using auxiliary parameters respectively. Biases and mean square errors (MSE) for these estimators were derived. The MSE of these estimators were c...
ABSTRACT Multidimensional scaling is a technique used to picture, visualize or locate objects in a map or Shepard diagram, Buja et ai, (2004). In this dissertation, the multidimensional scaling method has been applied to visualize approximate Iodations of eleven sampled local governments in Kebbi State. The symmetric distance matrix 'D' has been processed from an atlas of Nigeria by Eunice, (1979). The data has been transformed into inner-product matrix B by double centering, using Mardi...
African trypanosomosis is a vector-borne disease that is caused by a flagellated protozoon of the genus Trypanosoma. Large populations of human and domestic animals are at risk of infections with trypanosomes in vast areas of sub-Saharan Africa where the disease is endemic. Human infections with trypanosomes are referred to as Human African Trypanosomosis (HAT) while animal infections are known as African Animal Trypanosomosis (AAT). These infections are more prevalent in the rural areas (Ato...
ABSTRACT This work presents an intelligent system for fault diagnosis for automobiles. The main goal of this work is to use the vast knowledge previously acquired from human experts by system experts, to visualize, localize and fix a fault in a car. The project is motivated by the need to guide car owners and motor mechanics in the maintenance and troubleshooting of motor problems without having to resort to assumptions. A rule-based artificial intelligence (AI) technique was used to establ...
ABSTRACT This research aimed at fitting the canonical correlation model that is capable of determining whether literacy level, age, marital status and gender are risk factors for HIV/AIDs. The data used is obtained from Heart to Heart centre situated in General Hospital Minna, Niger State in June 2013. The Statistical package used to analyze the data is NCSS (Number Cruncher Statistical System) 2007 package and the result shows that the first set of variables measured the correlation of ...
ABSTRACT The problem of spurious correlation analysis, e.g. Pearson moment-product correlation test is that the data need to be normally distributed. This research work compares spurious correlation methods using some non-normal probability distributions in order to obtain the method with the best degree of association among them. The methods were compared using proportions of rejecting true null hypothesis obtained from t and z test statistics for testing correlation coefficients. Data ...
ABSTRACT The study was conducted to determine the abundance of mosquito species within Sokoto metropolis. Three (3) locations, which are Danbuwa, Gobirawa and GidanIgwai, in three (3) Local Government Areas, namely; DangeShuni, Sokoto South and Sokoto North Local Government Areas respectively, were sampled out of the five (5) Local Government Areas that make up Sokoto Metropolis were sampled. A total of 341 Mosquitoes species belonging to two genera were collected. The genera identified ...
ABSTRACT Background Antiretroviral therapy (ART) and drug resistance studies have focused almost exclusively on human immunodeficiency virus type 1 (HIV-1). Thus there is limited information on patients infected with HIV type 2 (HIV-2). In Ghana, the HIV epidemic is characterized by the domination of HIV-1 with the co-circulation of HIV-1 and HIV-2. HIV-2 is known to be naturally resistant to some antiretroviral drugs including non-nucleoside reverse transcriptase inhibitors (NNRTIs) and pr...
Abstract Malaria pathogenesis is an intricate process mediated by factors found in both the host and the parasite. The adaptive immune response to the most lethal malaria parasite, Plasmodium falciparum, remains to be fully comprehended. Meanwhile, T cells, which are critical for the host responses interact with antigens coupled with MHC molecules, through their membrane surface-expressed T cell receptor (TCR). These TCRs are produced by a process of imprecise gene rearrangement called V(D)J ...
A BSTRA CT The consumer’s perception of quality has been identified as the benchmark for quality around which all processing and marketing activities must revolve in order to achieve maximum profitability in industry, hi spite of this awareness, the consumer’s perception o f quality is yet to be fully understood to enable manufacturers translate consumer needs and expectations into business success. A number o f factors account for this failure including the complexity, subjectivity and m...
ABSTRACT The aim of this study was in two to investigate; firstly, (i) location of radiosensitive organs in the interior of four (4) paediatric anthropomorphic phantoms, and, secondly, (ii) effectiveness of single and double bismuth thyroid shields, distance between shield and phantom surface, during paediatric multi-detector computed tomography (MDCT) using fixed tube current (FTC) and automatic exposure control (AEC) on dose reduction and image quality. Four (4) paediatric anthropomorphic p...
