Head Tilt Classification Using Fft-Pca/Svm Algorithm

ABSTRACT The complexity of a face’s components originates from the constant variations in the facial component that occur with respect to time. Notwithstanding these variations, humans recognize a person very easily using physical characteristics such as face, voice, gait, etc. Automatic face recognition deals with extracting these essential features from an image, placing them into a suitable representation and performing some kind of recognition on them. This study presents an assessment...

Statistical analysis of socio-economic determinants on child labour and schooling in ghana.

ABSTRACT The objective of this study was to find the socio-economic determinants of child labour and schooling in Ghana. To this end, the 2003 Ghana Child Labour Survey data was analysed. The main techniques used were the simple logistic regression and multilevel logistic regression analysis. Results of the analysis showed that gender of head of household, marital status of parents, father’s occupation, mother’s occupation, relationship to head of household, place of residence, literacy ...

Lyapunov Functions In Epidemiological Modeling

Abstract In this mini thesis, we study the application of Lyapunov functions in epidemiological modeling. The aim is to give an extensive discussion of Lyapunov functions, and use some specific classes of epidemiological models to demonstrate the construction of Lyapunov functions. The study begins with a review of Lyapunov functions in general, and their usage in global stability analysis. Lyapunov’s “direct method” is used to analyse the stability of the disease-free equilibrium. More...

An Assessment Of Built-Up Expansion In Usmanu Danfodiyo University, Sokoto

ABSTRACT This research project is an assessment of built-up expansion in Usmanu Danfodiyo University, Sokoto from 2007 to 2015. Data for this research project was collected from both primary and secondary sources. The primary source of data include field observation, interview and satellite imageries. While secondary data include relevant published materials such as textbooks, journal articles, dissertations, reports, and the internet. The method used is satellite image processing, image clas...

Single Nucleotide Polymorphisms In Insulin-Like Growth Factor (Igf) Genes And Their Associations With Growth In Local Guinea Fowls (Numida Meleagris) Of Ghana

ABSTRACT Due to the pivotal role of Insulin-like Growth Factor 1 (IGF1) and Insulin-like Growth Factor 2 (IGF2) in growth regulation of poultry, the IGF1 gene (gIGF1) and IGF2 gene (gIGF2) in guinea fowl were examined as candidate genes for early growth in helmeted guinea fowls (Numida meleagris) from three populations of Northern Ghana (TPNG). Keets hatched from eggs collected from 32 sample locations comprising 11 subpopulations across three main populations located in Upper East Region, U...

Determinants Of All-Cause Maternal Mortality In Ghana: A Multivariate Decomposition Analysis Of 2007 And 2017 Ghana Maternal Health Surveys

ABSTRACT Background Maternal mortality has seen a significant decline in Ghana over last decade. Stakeholders and government continue to invest in strategic policies aimed to further decrease the ratio of maternal mortality. To achieve the desired results, interventions must be tailored toward specific factors in order to further strengthen the remedy to this health menace. Even though, there has been a decline over the years, international target and standards yet to be achieved. Method Ana...

Entomological Assessment Of Lymphatic Filariasis Transmission In Selected Communities In Ghana

ABSTRACT The resurgence of lymphatic filariasis (LF) infection after several rounds of Mass Drug Administration (MDA) has been the main reason behind constant monitoring of treatment. The MDA is designed to interrupt transmission by reducing microfilaraemia in a community to a threshold that local vectors may not be able to pick up microfilariae (MF) during a blood meal. The current study has been carried out to determine whether transmission had actually been interrupted following stoppage o...

Extended Spectrum Beta-lactamaseproducing Bacteria: Molecular Studies And Effects Of Medicinal Plants

ABSTRACT   Molecular studies of ESβL-producing bacteria isolated from clinical samples was determined as well as the effects of medicinal plants on the isolates. The study was conducted from September 2013 to September 2015. A total of 480 bacterial isolates (250 from urine, 110 from wound swab & 120 from HVS & US)  were used. The knowledge, attitude and practices (KAP) of health workers in Imo State towards multiple antibiotic resistant bacterial isolates and extended spectrum beta-lacta...

Finite Element Method With Damping Control Multi-Step Methods Approach To One Boundary Value Problem For The Wave Equation

ABSTRACT Over the previous years finite element method (FEM) has become a powerfully tool to approximate solution of differential equations and prove their existence. The purpose of this research is to introduce and describe a number of the finite element method (FEM) technique applied to problems for partial differential equations (PDEs) with special attentions to the hyperbolic problems in case of wave and damped wave equations. Another aim is to study the one boundary value problem (BVP) ...

Applying Genetic Algorithms And Heuristic Search To Automate Course Timetabling For The University Of Dodoma

ABSTRACT In this study, a Genetic Algorithm approach coupled with an internal Heuristic Search strategy is applied to attempt automation of course-teaching timetable generation for the University of Dodoma while trying to make the solution as general as possible. In designing the algorithm, course timetabling constraints of the institution are identified and a general encoding scheme is used to represent the problem. Then, a Genetic Algorithm is designed and implemented with a two-point cros...

Comparative Analysis Of The Data Mining Classification Algorithms For The Diagnosis Of Malaria

ABSTRACT Data mining is the process of determining patterns, discovering correlations, trends or relationships in the area with large data sets Information Technology, medical science, biology, education, and human resources. In Healthcare, DM is useful in medical data to anticipate novel, useful and potential knowledge that can save a life, lessen treatment cost, increases diagnostic and prediction accuracy as well as save human resources. Data mining contains several techniques such as ano...

Characterization of antimicrobial resistant pseudomonas spp. And other bacteria from infected wound

ABSTRACT Background: Wound infections mostly caused by Pseudomonas are on the increase in hospitals in Ghana. Most of these infected wounds are very difficult to treat with available antibiotics. This failure of treatment has resulted in increased need for healthcare, undue financial burden on both hospitals and patients and finally death of many of these patients. This has become a source of worry for both patients and healthcare providers in Ghana. General Aim: The main aim of this study w...

Partial Purification And Characterization Of Acetylcholinesterase From Adult Onchocerca Volvulus

ABSTRACT (' V ) Acetylcholinesterase (AChE) from adult Onchocerca volvulus was extracted in either 5OmM Tris-HCl, containing Triton X-100 (detergent buffer) or plain 50mM Tris-HCl (lowsalt buffer) Gel chromatography on Sephacryl S-300 column, of both the detergent buffer and the low-salt buffer extracts gave two components each./ The two components of the detergent buffer gave purification factors of 12 and 13 folds and yields of 22 and 23% respectively; those of the low-salt buffer had puri...
