Abstract: Kaposi’s sarcoma is a common AIDS-defining cancer that has continued to afflict patients living with HIV-1, especially, individuals who are currently not on HAART or whose HIV-1 status is not known. Even individuals who have had a prior HHV-8 infection and are on HAART are at an increased risk of developing KS whenever drug failure occurs and when one develops drug resistance to the drugs being administered. Like other herpesvirus, KS associated herpesvirus (KSHV), also known as ...
Abstract: Some new generalized distributions called the new Gamma Lindley-Log-logistic (GLLLoG) distribution, new Weibull Generalised-G (NWG-G) family of distributions and the Exponentiated Half-Logistic Odd Lindley-G family of distributions are proposed and presented. These distributions contain several distributions such as Half-Logistic, Odd Lindley, Lindley, Log-Logistic, new-Rayleigh generalized-G, new exponential generalized-G, new Rayleigh-G and the new-Weibull-G family of distributio...
Abstract: Let Grk,n be the complex Grassmann manifold of k-linear subspaces in ℂn. We compute rational relative Gottlieb groups of the embedding i:Grk,n Grk,n+r and show that the G-sequence is exact if r≥kn-k.
Abstract: A mathematical model of meningococcal meningitis with incidence dependent self-protection measure and vaccination is formulated and analysed. The vaccination considered is assumed to be given to everyone and is information dependent. It is shown that the disease free equilibrium is globally asymptotically stable, which implies that if the disease reproduction number R0 can be reduced to a value less than unity then it is possible to eradicate the meningococcal meningitis. In additi...
ABSTRACT, Family background has been enlightened as of great importance in molding the performance of academic performance of students in schools worldwide. This study therefore investigated the influence of family background on student’s academic performance in science subjects in secondary schools in Makindye division of Kampala capital city of Uganda. This study focused on the influence of parental marital status, level of education of the parents and family income on student’s academi...

ABSTRACT This research production and sales of flours in Dangote aimed to determine whether there exist a relationship between sales and production of flours and also to determine if there is increase in the sales and production. Regression analysis and product moment correlation coefficient were used to analyze the data. The results of the analysis revealed that there is perfect correlation between the sales and the production of Dangote flours and also regression analysis revealed that th...

Abstract This project is on comparative analysis of amount of premium paid and claims settled on fire, motor and life policies in Kwara Insurance Broker’s Limited, Ilorin from 1996-2005 was aimed to analysis the trend of insurance in Nigeria as regards to the three policies mentioned above regression analysis and correlation was use to analyse the data. Sequences to the analysis carried out, it revealed that the amount of claims settled does not depend on the amount of premium paid. The lif...
Abstract We propose Asap, an adaptive stochastic optimization algorithm for principal component analysis (PCA), in the increasing block size setting. Asap is a novel generalized variant of the classical Oja’s algorithm (Oja, 1982), but can compute top-k principal components without the necessity of tuning the step size. Asap performs PCA by first-order gradient-based optimization based on adaptive estimates of lower-order moments as with Adagrad and Adam. We provide a theoretical guarantee ...
ABSTRACT Consider the problem of r t / randomly distributed points in a unit n-ball and the convex hull created by these points. Let ~ 11 be r.t times the r-content of an rsimplex whose p vertices are in the interior and r + /- p vertices on the boundary of a unit n-ball. Explicit expressions for the exact distribution functions of ~,, are given when r 1 / points are independently, and identically distributed according to the Uniform distribution. The exact distributions are obtained using t...
Abstract We find new classes of exact solutions for the Einstein-Maxwell field equations. The solutions are obtained by considering charged anisotropic matter with a linear equation of state consistent with quark stars. The field equations are integrated by specifying forms for the measure of anisotropy and one of the gravitational potentials which are physically reasonable. A general feature of our models is that isotropic pressures are regained when certain parameters vanish; this behaviou...
ABSTRACT Data has increased at an exponential rate and has outpaced our capability to analyze it. However, new ways of data analysis, which thrive in big data such as Machine Learning (ML) have emerged. This study explores Machine Learning by creating a Machine Learning algorithm based on Support Vectors. This was done by converting mathematical formulations into a computer algorithm that was then used for data classification. The algorithm was evaluated and compared to other algorithms. The ...
ABSTRACT Research work examines the accuracy and forecasting performance of volatility models for the KES/USD exchange rate return in Kenya using the EGARCH and TARCH. In fitting these models to the daily and monthly exchange rate returns data collected from CBK which extended from the period January 2008 to December 2015, In this study, performance of Time series models ( asymmetric EGARCH and TARCH models) in forecasting the volatility behavior of Kenya FOREX market was examined. Daily FORE...
