ABSTRACT The impacts of extremely high temperatures on plants, human beings and animals’ health have been studied in several parts of the world. However, extreme events are uncommon and have only attracted attention recently. In this study, extreme temperature behaviour was modelled through the application of extreme value theory using maximum monthly temperatures over a 32 years period. Data on monthly maximum temperature from the Upper East Region were modelled using generalized extreme ...
Abstract Some inequalities involving the (q, k)-digamma function are presented. These results are the (q, k)-analogues of some recent results.
Abstract In this paper, the (q, k)-analogues of some inequalities involving the Psi function are presented. These results generalize some earlier results presented by W. T. Sulaiman. The approach is based on some mononicity properties of some functions involving the ψq,k function.
ABSTRACT Given a Lie algebra g and its complexication gC, the representations of gC are isomorphic to those of g. Moreover, if g is the corresponding Lie algebra of a connected and simply connected Lie group G then the representations of the Lie group in question are isomorphic to those of gC. This thesis explains the basic concepts of Lie groups and Lie algebras. Further, the basic representation theory of Lie groups and Lie algebras, particularly those of semisimple Lie algebras is discuss...
ABSTRACT The study of Green’s Functions and applications of BVPs solving different integration has been put in place in order to provide a broad understanding to the existence of Green’s Functions on solving Ordinary Differential Equations with nth order. The Green’s Functions plays an important role in solving boundary value problems of Ordinary Differential Equations. The solutions of some BVPs for linear ODEs can be denoted by its Green’s Function. Some BVPs for nonlinear Differen...
ABSTRACT The main objective of this study is on a global solution of the Navier-Stokes equations with internal body forces. The internal body forces play very important in both theory and application with Navier-Stokes equations. We discussed about the general solution for ordinary differential equations (ODES) and partial differential equations (PDES). Also they used the MAC model for incompressible flow. The study has been conducted in order to provide abroad understanding the existence of...
Abstract Some inequalities involving the p-digamma function are presented. These results are the p-analogues of some recent results.
ABSTRACT This study aimed at finding a minimum cost of investment in Renewable Energy (RE) sources, specifically in Hydro, Wind, Solar and Biomass that will meet projected demand levels in specific time periods in the future and ensure a modest (10%), (20%) or an ambitious (30%) incorporation of these renewable energy sources. To do this, a relevant optimization model was formulated and discussed. The Levelized Cost of Energy (LCOE) model adopted for the purpose was also discussed in detail....
Abstract Some inequalities involving the q-digamma function are presented. These results are the q-analogues of some recent results.
ABSTRACT This study was undertaken to examine the nature and quantify the magnitude of Genotype by Environment interaction effects on rice (Oryia Sativa L.) grain yield and to determine the most stable and winning genotype (s) in terms of yield stability and performance in two rice producing hubs. The study was conducted at four locations within two rice producing hubs in Northern Ghana on fifteen (15) rice genotypes including a checking genotype GR18 red. A randomized complete block design ...
ABSTRACT The role of weight-for-age babies in the early childhood and its effects on later lives of children cannot be over emphasized. Birth weight according to Murthy (1991) is a key indicator of the incidence of infant mortality and thus, a reflection of the socio-economic development of a country. The main objective is to use statistical models to assess the change in weight of children over time and to investigate whether maternal characteristics such as marital status, educational leve...
Abstract Some inequalities involving the (p, q)-digamma function are presented. These results are the (p, q)-analogues of some recent results.
ABSTRACT It is known that certain polynomials of degree one, with integer coefficients, admit infinitely many primes. In this thesis, we provide an alternative proof of Dirichlets theorem concerning primes in arithmetic progressions, without applying methods involving Dirichlet characters or the Riemann Zeta function. A more general result concerning multiples of primes in short-intervals is also provided. This thesis also considers problems concerning the existence of odd perfect numbers. T...
Abstract. In this paper, some inequalities for the ratios of generalized digamma functions are presented. The approache makes use of the series representations of the (q, k)-digamma and (p,q)-digamma functions.
ABSTRACT Residue Number System (RNS) has found a wide spread usage in a number of digital signal processing applications such as digital filtering, Discrete Fourier transform , Convolution, Correlation, communication, and cryptography. This is due to the following RNS inherent features: modularity, parallelism, carry free addition, borrow free subtraction, and fault tolerance. The major challenges ofRNS architecture lie in moduli set selection and in the reverse conversion (conversion from r...
