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 ... -
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. ... -
On the convexity of Stampfli's numerical range
(Cambridge University Press, 1996-02)This paper investigates a certain type of numerical range introduced by Stampfli. In particular, we investigate the convexity of this set of elements of operators on Hilbert spaces and its relationship to the algebra ... -
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 ... -
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 ... -
A Functional Calculus for (α, α+ 1)− type R Operators
(Int. Journal of Math. Analysis,, 2010)A closed densely defined operator H, on a Banach space X, whose spectrum is contained in R and satisfies (z − H)−1 ≤ c z α | z|β ∀ z ∈ R with z α := |z|2 + 1 (1) for some α , β ≥ 0; c > 0, is said to ... -
Aspects of (pq) summing multipliers
(Vdm verlag Dr. Muller aktiengeselischaft & co. kg., 2010)A sequence (uj)j2N of operators in L(X; Y ) is a (p; q)-summing multi- plier (or (p; q)-summing sequence of operators), in short (uj) 2 `¼p;q (X; Y ), if there exists a constant C > 0 such that, for any ¯nite collection ... -
Norms of Inner Derivations on Norm ideals
(Int. Journal of Math. Analysis, 2010)Let B(H) be the algebra of bounded linear operators on a Hilbert space H and J be a norm ideal in B(H). We investigate the relationship between the diameter of the numerical range of an operator A ∈ B(H) and the norm ... -
Norm of a derivation and hyponormal operators
(Int J Math Anal, 2010)We characterize when the norm of inner derivation on a norm ideal equals that on the quotient algebra. We further investigate norms of inner derivations implemented by normal and hyponormal operators on norm ... -

Incremental Modernization of Statistics Teaching and Curriculum at Maseno University, Kenya
(International Association of Statistical Education, 2010)Modernisation of statistics teaching is a continual problem the world over. The advances in statistical methods and tools along with the growing demand of applied practitioners creates a dual need of people with the ... -
Norms of Derivations Implemented by S-Universal Operators
(International Journal of Mathematical Analysis, 2011)Let H be a complex Hilbert space and B(H) the algebra of all bounded linear operators on H. For A, B ∈ B(H), we define inner derivations implemented by A,B respectively on B(H) by ΔA(X) = AX−XA, ΔB(X) = BX−XB and a ... -
On the Generalized Reid Inequality and the Numerical Radii
(Applied Mathematical Sciences, 2011)In this paper, we extend the generalized Reid inequality to include the numerical radii for the product of two Hilbert space operators. Mathematics Subject Classification: 47A12, 47A30, 47A63 -
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 ... -
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 ... -
A cost - benefit analysis of substituting bamboo for tobacco: a case study of smallholder tobacco farmers in south Nyanza, Kenya
(Science Journal Publication, 2012)This study examined the economic and financial benefits and costs of farming bamboo as a crop substitute of tobacco in four (4) districts in South Nyanza, Kenya. The World Health Organization Framework Convention on ... -
Orthogonality of elementary operators in normed spaces and their applications
(SAMSA 2012 mathematics conference proceedings, 2012-11)Malaria is a major public health concern, especially among pregnant women and children under the age of five. It is a leading cause of morbidity and mortality in Malawi, accounting for fourty percent of out-patient ... -
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 ...
