Velocity Profile for Magnetohydrodynamic Flow in Straight Horizontal Elliptical Pipe
(Applied Mathematical Sciences, 2021)Velocity profile for Magnetohydrodynamic (MHD) fluid flow in a straight long pipe with elliptical cross section has been investigated. Governing equations are partial differential equations comprising Ohm’s law of ... -
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 ... -
On the Zero Divisor Graphs of Finite Rings in Which the Product of Any Two Zero Divisors Lies in the Coefficient Subring
(Journal of Mathematics and Statistical Science, 2016)Let r be a positive integer and 2 ≤ ∈k . Let ( ) kr k GR p p, be a Galois ring of order kr p and characteristic k p . Consider, ( ) kr k R GR p p U = ,⊕ where U is a finitely generated ( ) kr k GR p p, module. If Z R( ... -
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 ... -
Models for Variable Premiums Payable to Benevolent Funds
(Hikari Ltd., 2020)he application of multiple life actuarial calculations have been studied by many authours for instance Elizondo [5] studied the construction of multiple decrement models from associated single decrement experiences. He ... -
On the Theory of Random Search
(University of Nairobi,, 1994)The problem of identifying one or more unknown elements belonging to a finite set So' containing n distinguishable elements is well known in literature. Designs used in this kind of investigation are known as search designs. ... -

Locally oriented noncrossing trees
(2015)We de ne an orientation on the edges of a noncrossing tree induced by the labels: for a noncrossing tree (i.e., the edges do not cross) with vertices 1; 2; : : : ; n arranged on a circle in this order, all edges are ... -
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 in degree ... -
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 ... -
Modeling of jumps and mean reversion in the Kenyan interest rates

A STUDY OF ATTITUDES OF TEACHERS AND PUPILS TOWARD THE TEACHING AND LEARNING Of M~THEMATICS RESPECTIVELY IN UPPER PRIMARY SCHOOLS IN MASIMBA EDUCATIONAL ZONE, IRIANYI DIVISION, KISII DISTRICT (KENYA) •
(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 ... -
Zero Inflated Poisson Mixture Distributions
(Applied Mathematical Sciences, 2017)This paper presents a method of constructing the Zero in ated Pois- son continuous mixture distributions which have applications in various fields. The distributions can be formed by either direct integration or integration ... -
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 ... -

Consistency Inference Property of QIC in Selecting the True Working Correlation Structure for Generalized Estimating Equations
(Science Publishing Group, 2019-06-29)Abstract: The generalized estimating equations (GEE) is one of the statistical approaches for the analysis of longitudinal data with correlated response. A working correlation structure for the repeated measures of the ... -
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 ... -
Fitting Time-series Models to Kisumu Rainfall Data for the Period 1961-2014
(Science Publishing Group, 2020-02-20)Abstract: Many small-scale farmers require adequate forecasts to help them plan for the rainfall. The National Meteorological Service provides forecasts seasonally, monthly and weekly. The forecasts are qualitative in ... -
OPEN EDUCATIONAL RESOURCES FOR STATISTICS TEACHING
(ISI/IASE, 2017)A series of papers at this conference have built on the African Data Initiative (ADI) which was started to improve statistical literacy and understanding. One immediate deliverables of this initiative has been new ...
