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. ... -
The Acoustic Wave Propagation Equation: Discontinuous Galerkin Time Domain Solution Approach
(Applied Mathematical Sciences Vol. 13, 2019, no. 16, 753 - 767, 2019)This paper discusses a finite element method, discontinuous Galerkintime domain approach that solves the 2-D acoustic wave equation incylindrical coordinates. The method is based on discretization of thewave ... -
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, ... -
Application of Principal Component Analysis to Crime Data, Case Study: Mathare Slums, Nairobi County in Kenya
(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 ... -
CONSTRUCTION OF MODIFIED THIRD ORDER ROTATABLE DESIGNS THROUGH PAIRWISE BALANCED DESIGNS
(2019-11-30)Rotatable designs are designed 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 technique valuable ... -
HYDRODYNAMIC ANALYSIS OF A FIXED INCLINE SLIDER BEARING
(2016-05-23)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 ... -
APPLICATIONS OF BAYESIAN METHODS IN ANALYSIS OF VARIANCE
(2016-05-20)Analysis of variance (ANOVA) is a standard method for describing and estimating heterogeneity among the means of a response variable across the levels of multiple categorical factors. In most experimental settings, ANOVA ... -
AN INVESTIGATION OF EFFECTS OF BOUNDARY LAYER THICKNESS
(2016-05-20)The motion of fluid substances can be described by the Navier-Stokes equations. These equations arise from the application of Newton's second Law of motion to a fluid. In this study, Navier-Stokes equations in two ... -
AN INVESTIGATION ON MAGNETOHYDRODYNAMICS FLUID FLOW BETWEEN TWO PARALLEL INFINITE PLATES SUBJECTED TO AN INCLINED MAGNETIC FIELD AND VARYING TEMPERATURES
(2016-05-20)Magnetohydrodynamics (MHD) is the study of electrically conducting fluids in the presence of magnetic fields. This study examined the motion of a viscous, electrically conducting and incompressible fluid flowing steadily ... -
DELAY DIFFERENTIAL EQUATION MODEL OF HIV-1 IN VIVO DYNAMICS IN THE PRESENCE OF ARV TREATMENT
(2016-05-18)ABSTRACT Many mathematical models have been developed to describe the immunological response to infection with human immunodeficiency virus (HIV-1). The models have been used to predict the evolutions of HIV-1 in vivo ...
