Deficiency indices and spectrum of fourth order difference equations with unbounded coefficients
(WILEY‐VCH Verlag, 2013-03)Using subspace theory together with appropriate smoothness and decay conditions, we calculated the deficiency indices and absolutely continuous spectrum of fourth order difference equations with unbounded coefficients. In ... -
Finite Solvable Groups with 4-Regular Prime Graphs
(African Institute for Mathematical Sciences, Master Thesis, 2013-05-23)In this research project, we seek to address the problem of deciding which nite simple graph is a prime graph of a nite group. In particular, we only focus on showing which 4-regular graphs can be prime graphs of some ... -
Various notions of orthogonality in normed spaces
(Elsevier, 2013-09-01)In this paper, we present various notions and aspects of orthogonality in normed spaces. Characterizations and generalizations of orthogonality are also considered. Results on orthogonality of the range and the kernel of ... -
The application of logistic regression in modeling of survival chances of HIV-positive patients under highly active antiretroviral therapy (HAART): A case of Nyakach District …
(Basic Research Journal, 2014)In Kenya the number of persons requiring antiretroviral Therapy (ART) in 2012 was over 90,000 while globally more than 1.4 million were under ART in the year 2012. Though ART treatment has decreased mortality of HIV associated ... -
Modeling trailer-traffic flow on a Kenyan highway
(2014)Traffic flow modelling is studied in order to ease congestion on roads. However, congestion is also caused by irregular occurrences, such as traffic accidents, poor roads, vehicle disablement, spilled loads and hazardous ... -
On necessary Conditions for scalars
(Hikari Ltd, 2014)In this paper, we give a characterization of scalar operators. In particular we show that a densely defined closed linear operator H acting on a reflexive Banach space X is scalar if it is of (0, 1) type R and f (H)≤ f∞ ... -
BUILDING STRENGTH FROM COMPROMISE; A CASE STUDY OF FIVE YEAR COLLABORATION BETWEEN THE STATISTICAL SERVICES CENTRE OF THE UNIVERSITY OF READING, UK AND MASENO UNIVERSITY, KENYA
(ICOTS, 2014)Statistics teaching and practice at Maseno University has benefited immensely from its collaboration with the Statistical Services Centre (SSC) at the University of Reading. The SSC, a self-sustaining entity providing ... -
A Probabilistic Estimation of the Basic Reproduction Number: A Case of Control Strategy of Pneumonia
(cience Publishing Group, 2014)Deterministic models have been used in the past to understand the epidemiology of infectious diseases, most importantly to estimate the basic reproduction number, Ro by using disease parameters. However, the approach ... -
Parameter Driven Dynamics of Trypanosomiasis in a Cattle Population
(HIKARI Ltd, 2014)In this paper we study the disease dynamics of trypanosomiasis in a cattle population. The compartmental model presented includes the wild animal population which provides an alternative feeding source for the tsetse ... -

Supply, Demand, Equilibrium, Deterministic, Stochastic, Logistic and Differential Equations
(INTERNATIONAL JOURNAL OF MULTIDISCIPLINARY SCIENCES AND ENGINEERING, 2014)In this paper, we use the Bernoulli Jump Diffusion (BJD) process to test for the existence and probability of jumps in the Kenyan interest rates. We test these using the Maximum Likelihood Estimation (MLE) method on the ... -
Option Pricing of an Asset with Seasonal and Periodic Supply
(International Journal of Multidisciplinary Sciences and Engineering, 2014)In option pricing the rate of change of asset price with time can be viewed to be directly proportional to the Walrasian [6] excess demand. Scholars such as Jacques [3] and Onyango [4], have used the excess demand concept ... -
On the norm of elementary operator
(Scientific Research Publishing, 2014-07-07)The norm of an elementary operator has been studied by many mathematicians. Varied results have been established especially on the lower bound of this norm. Here, we attempt the same problem for finite dimensional operators. -
Jumps in the Kenyan Interest Rates
(INTERNATIONAL JOURNAL OF MULTIDISCIPLINARY SCIENCES AND ENGINEERING, 2014-11-11)— In this paper, we use the Bernoulli Jump Diffusion (BJD) process to test for the existence and probability of jumps in the Kenyan interest rates. We test these using the Maximum Likelihood Estimation (MLE) method on ... -

Groups of isometries associated with automorphisms of the half-plane
(Mississippi State University, 2015)The study of integral operators on spaces of analytic functions has been considered for the past few decades. However, most of the studies in this line are based on spaces of analytic functions of the unit disc. For the ... -
Combinatorics of oriented trees and tree-like structures
(Stellenbosch University, 2015)In this thesis, a number of combinatorial objects are enumerated. Du and Yin as well as Shin and Zeng (by a different approach) proved an elegant formula for the number of labelled trees with respect to a given ... -
Exploring the Role of Extra Curricula Maths Camps and Clubs in Kenya and Beyond
(2015)For the last four years Maseno University, Kenya, has been running a maths camp bringing together both international and local, lecturers and teachers to engage secondary students in the subject through puzzles, games, ... -
