On Numerical Range of Multiplication Operator
(International Journal of Mathematical Analysis, 2019)Let H be an in nite dimensional complex Hilbert space and A;B 2 B(H) where B(H) is the C -algebra of all bounded linear operators on H. Let MAB : B(H) ! B(H) be a multiplication operator induced by A and B de- ned ... -
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 ... -
Training of lecturers at Maseno University, Kenya
(Proceedings of the ICOTS8 conference, 2010)Lecturers in Kenyan universities usually start their work without any prior training on how to teach students. Hence the teaching tends to be traditional and new training techniques are rarely implemented. For effective ... -
Using e-learning to engage Mathematics and Statistics Students in a Kenyan University
(12th International Congress on Mathematical Education, 2012)Two introductory courses to statistics were taught to first year mathematics and statistics students as part of an initiative to introduce them to computers. The courses were offered using a blended approach which included ... -
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 ... -
Envisioning Change in the Statistics-Education Climate.
(Statistics Education Research Journa, 2020-02-01)The African Data Initiative started as a crowd-sourced campaign to improve the teaching of statistics in African universities. The analysis of climate data provides one suitable context to illustrate ideas that lead to a ... -
The algebra of smooth functions of rapid descent
(JOOUST, 2009)A bounded operator with the spectrum lying in a compact set V ⊂ R, has C∞(V ) functional calculus. On the other hand, an operator H acting on a Hilbert space H, admits a C(R) functional calculus if H is self-adjoint. So ... -
Operators with slowly growing resolvents towards the spectrum
(International Journal of Pure and Applied Mathematics, 2009-03)A closed densely defined operator H, on a Banach space X, whose spectrum is contained in R and satisfies -
On Numerical and Centre Values Range
(Int. Journal of Math, 2010)This paper follows [1] in the quantitative study of Numerical Ranges introduced by Stampfli [9]. In particular, we consider a family of mutually orthogonal projections and investigate how a numerical range can be related ... -
Mathematical Model for Pneumonia Dynamics with Carriers
(2013)There are major advances which have been made to understand the epidemiology of infectious diseases. However, more than 2 million children in the developing countries still die from pneumonia each year. The efforts to ... -
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 ... -
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∞ ... -
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 ... -
International Journal of Mathematical Archive-2 (10), 2011, Page: 2027-2029 Available online through www. ijma. info ISSN 2229–5046
(IJMA, 2011)In this paper, the age-structured population matrix, also known as Leslie matrix, has been extended to model the dynamics of migrating individuals. Aggregation techniques have been used to estimate the parameters of the ... -
Zero Inflated Poisson Mixture Distributions
(Applied Mathematical Sciences, 2017)This paper presents a method of constructing the Zero inflated Poisson continuous mixture distributions which have applications in various fields. The distributions can be formed by either direct integration or integration ... -
Inference Properties of QIC in the Selection of Covariates for Generalized Estimating Equations
(HIKARI Ltd, 2019)The Quasi-likelihood information criterion (QIC)which results from utilizing Kullbacks I-divergence as the targeted discrepancy is widely used in the GEE framework to select the best correlation structure and the best ... -
Consistency Inference Property of QIC in Selecting the True Working Correlation Structure for Generalized Estimating Equations
(Science Publishing Group, 2019-06-29)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 outcome ... -
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 ... -
Fitting Time-series Models to Kisumu Rainfall Data for the Period 1961-2014
(Science Publishing Group, 2020-02-20)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 nature hence ... -
