HYDRODYNAMIC ANALYSIS OF A FIXED INCLINE SLIDER BEARING
(University of Eldoret, 2016)In the present day technological scenario, machines rotating at high speeds and carrying heavy rotor loads are used. As a result, fixed incline slider bearings are used. They are designed for high axial loads. When a bearing ... -
THE ACOUSTIC WAVE PROPAGATION EQUATION: THE DISCONTINUOUS GALERKIN TIME DOMAIN SOLUTION APPROACH
(University of Eldoret, 2019)This thesis presents a finite element method, discontinuous Galerkin time domain approach that solves the 2-D acoustic wave equation in cylindrical coordinates. The method is based on discretization of the wave field into ... -
FINITE DIFFERENCE SCHEMES ARISING FROM OPERATOR SPLITTING FOR SOLVING TWO DIMENSIONAL SYSTEM OF BURGERS’ EQUATION
(University of Eldoret, 2016)Solving Burgers equation continues to be a challenging problem. Burgers‟ equation is a fundamental partial differential equation from fluid mechanics. It occurs in various areas of applied mathematics, such as modeling of ... -
EFFECTS OF PRICES BEFORE AND AFTER TAX, AND INCOME PER CAPITA ON TOBACCO CONSUMPTION IN KENYA: COINTEGRATION APPROACH
(University of Eldoret, 2021)Smoking of cigarette is regarded as one of the most cause of deaths among other factors in the world. It is also a causative agent of the various cancerous diseases. It is by fact though preventable, the major cause ... -
SOLVING MATHEMATICAL WORD PROBLEMS IN SECONDARY SCHOOLS: A CASE OF TINDERET SUB-COUNTY, NANDI COUNTY KENYA
(University of Eldoret, 2020)Mathematical word problems are concepts taught at the end of every topic to allow students apply the content that was taught. The study focused on investigating the student’s difficulties in solving mathematical word ... -
ON ALMOST SIMILARITY AND SOME CLASSES OF OPERATORS IN HILBERT SPACES
(University of Eldoret, 2021)Similarity is a recent area of study on classes of operators in Hilbert spaces. The study of operators, under similarity and quasisimilarity concepts, motivated researchers to extend their research to almost similarity ... -
ON NUMERICAL RANGE OF SOME CLASSES OF OPERATORS IN HILBERT SPACES
(University of Eldoret, 2021)The numerical range of operators in Hilbert spaces has been researched by several authors. The properties of the numerical range play an important role in identifying the behaviour of operators in Hilbert spaces. It ... -
On the Norm of Basic Elementary Operator in a Tensor Product
(International Journal of Scientific and Innovative Mathematical Research., 2019)In this paper, we determine the norm of an elementary operator in a tensor product. More precisely, we investigate the bounds of the norm of a basic elementary operator in a tensor product. We employ the techniques of ... -
ON THE NORM OF AN ELEMENTARY OPERATOR OF FINITE LENGTH IN A 𝑪∗ALGEBRA
(Journal of Progressive Research in Mathematics(JPRM), 2018)Properties of elementary operators have been studied over the past years especially the norm aspect. Various results have been obtained on elementary operatorsof different lengths using different approaches. ... -

Construction of a Five-Level V-Dimensional Modified Third Order Rotatable Designs using a Pair of Pairwise Balanced Designs
(African Journal of Education, Science and Technology, 2019)Rotatable designs are devised for use of response surfaces. Rotatability is evidently a greatly popular property for Response Surface Methodology (RSM). RSM is a group of statistical and mathematical ... -
Need to make people believe science-science is reliable and means truth
(Open Journal of Social Science,, 2019)Science is the engine that drives the wheel of development. Consequently, there is a need for people to have faith in science and believe its facts and truths. This paper has looked into ... -
Analysis and Modelling of Extreme Rainfall: A Case Study for Dodoma, Tanzania
(Asian Journal of Probability and Statistics, 2019)The analysis of climate change, climate variability and their extremes has become more important as they clearly affect the human society and ecology. The impact of climate change is reflected by the change of frequency, ... -

(AmericanJournalofTheoreticalandAppliedStatistics, 2019)The study focuses on statistical analysis of causes of crimes in Mathare slums, Nairobi county using data collected via questionnaires in April 2018.The Correlation analysis was carried out to explain the ... -
Central Limit Theorem and Its Applications in Determining Shoe Sizes of University Students
(Asian Journal of Probability and Statistics, 2019)The Central limit theorem is a very powerful tool in statistical inference and Mathematics in general, since it has numerous applications such as in topology and many other areas. For the case of probability theory, it ... -
Parametric Point Estimation of the Geeta Distribution
(International Journal of Statistical Distributions and Applications, 2018)Geeta distribution is a new discrete random variable distribution defined over all the positive integers with two parameters. This distribution belongs to the family of Location-parameter (LDPD) system and is of the form ... -
Optimal Kiefer Ordering of Simplex Designs for Third-Degree Mixture Kronecker-Models with three ingredients.
(Mathematical Theory and Modeling, 2019)This paper investigates the Kiefer optimality in the third-degree Kronecker model for mixture experiments. For mixture models on the simplex, a better design is obtained, by matrix majorization that yields a larger ... -
Parametric Interval Estimation of the Geeta Distribution
(International Journal of Statistics and Probability, 2018)t is well known that the sample mean is the estimator of a population mean in mathematical statistics from a given population of interest as a point estimator which assume a single number that is obtained ... -
