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 ... -
Portfolio optimization for extended (p, q) –binomial cox –ross- rubinstein model
(SSAR Publishers, 2024-03-11)In this paper, we focus on establishing optimization conditions for the extended binomial Cox-Ross-Rubinstein (CRR)model, particularly in the context of managing portfolios in life insurance under varying noise conditions. ... -
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 ... -
Provable, Secure & Democratic Election Model
(INTERNATIONAL JOURNAL OF MULTIDISCIPLINARY SCIENCES AND ENGINEERING, 2017)Democracy is founded on the principle of elections and opinion expression capabilities. Bimber & Leggewie foresaw e-democracy. Voting is an information transfer model. Trust is essential to communication channel but ... -
Reachability in complete t-ary trees
(Annals of Mathematics and Computer Science, 2023-10-01)Mathematical trees such as Cayley trees, plane trees, binary trees, noncrossing trees, t-ary trees among others have been studied extensively. Reachability of vertices as a statistic has been studied in Cayley trees, plane ... -
Reachability results in labelled t-ary trees
(Open Journal of Mathematical Sciences, 2021)In this paper, we prove some new formulas in the enumeration of labelled t-ary trees by path lengths. We treat trees having their edges oriented from a vertex of lower label towards a vertex of higher label. Among other ... -
Recursive Relation for Zero In ated Poisson Mixture Distributions
(2017)The paper extends the work of Sarguta who derived recursive re- lations for univariate distributions by considering the ZIP continuous mixtures. The paper gives a recursive formular which can be used to evaluate the mixed ... -
Recursive Relation for Zero Inflated Poisson Mixture Distributions
(HIKARI Ltd, 2017)The paper extends the work of Sarguta who derived recursive re lations for univariate distributions by considering the ZIP continuous mixtures. The paper gives a recursive formular which can be used to evaluate the mixed ... -
Refined enumeration of 2-noncrossing trees
(Academic Publishing House, 2021)A 2-noncrossing tree is a connected graph without cycles that can be drawn in the plane with its vertices on the boundary of circle such that the edges are straight line segments that do not cross and all the vertices ... -
Refined enumeration of k-plane trees and k-noncrossing trees
(2022)A k-plane tree is a plane tree whose vertices are assigned labels between 1 and k in such a way that the sum of the labels along any edge is no greater than k+1. These trees are known to be related to (k+1)-ary trees, and ... -
Some Properties of the Essential Numerical Range on Banach Spaces
(HIKARI Ltd,, 2017)We study the properties of the essential algebraic numerical range as well as the essential spatial numerical range for Banach space operators. Mathematics Subject Classi cation: 47A10; 47A05; 47A53 -
Spatial Comparison and Quality Check of Farmer-recorded Daily Rainfall Data; A Case of Nyakach and Soin-sigowett, Kenya
(Science Publishing Group, 2020-01-09)Small scale farming is currently still heavily dependent on rainfall in developing nations. With the challenge of climate change, many innovations are proposed to help the farmers mitigate and adapt. The use of historical ... -
Spatial Comparison and Quality Check of Farmer-recorded Daily Rainfall Data; A Case of Nyakach and Soyain-sigowett, Ken
(Science Publishing Group, 2020-09-01)Abstract: Small scale farming is currently still heavily dependent on rainfall in developing nations. With the challenge of climate change, many innovations are proposed to help the farmers mitigate and adapt. The use of ... -
Spectra of Composition Groups on the Weighted Dirichlet Space of the Upper Half-Plane
(Springer, 2020)We prove that the group of weighted composition operators induced by contin uous automorphism groups of the upper half plane U is strongly continuous on the weighted Dirichlet space of U, Dα(U). Further, we investigate ... -
Spectral analysis of certain groups of isometries on Hardy and Bergman spaces
(Academic Press, 2017-12-15)Using the similarity theory of semigroups as well as spectral theory, we obtain the resolvents of the generators of strongly continuous groups of isometries on the Hardy and Bergman spaces. These groups are obtained as ... -
Statistical trend analysis of residential water demand in Kisumu City, Kenya
(Science Publishing Group, 2015-04-16)This study sought to analyse trend in the monthly water demand data series in Kisumu city at both seasonal and non-seasonal levels using the parametric method of Ordinary Least Squares (OLS) and non-parametric methods of ... -

(University of Kenyatta., 1986)The purpose of the study was to identify the attitudes held by the primary school teachers and pupils toward the teaching and learning of Mathematics respectively. The study was done at Masimba Educational zone, Irianyi ... -
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 ... -
