On numerical ranges of convexoid operators
(G.I publications, 2017-02)Numerical range is useful in studying operators on Hilbert spaces. In particular, the geometrical properties of numerical range often provide useful information about algebraic and analytic properties of an operator. The ... -
On Tensor Products and Elementary Operators
(Core, 2018)In this paper we describe operator systems and elementary operators via tensor products. We also discuss norms of elementary operators. -
On the Effects of Motocycle Accidents and its Trends (A Case of Kenya)
(JKUAT press, 2016)This study analyzes recent data of accidents’ prevalence in Kenya and investigates whether there might be new trends in areas formerly not prone to accidents. Polynomials of order 6 are found best suited for accidents’ ... -
On the similarities in properties of essential numerical range and Davis-Wielandt shell of Hilbert space operators
(International Journal of Innovative Research and Advanced Studies (IJIRAS), 2017-07)Let be an operator on an infinite dimensional Hilbert space . Denote the essential numerical range of the operator by and the Davis-Wielandt shell of the operator by . We review the properties of the essential numerical ... -
On the structures of quotient groups
(Academic Publications, 5/22/2009)Let J be the Jacobson radical of a commutative completely primary finite ring R such that J k 6= (0) and J k+1 = (0). Then R/J ∼= GF(p r ), the finite field of p r elements, and the characteristic of R is p k where k ≥ 2 ... -
On Theory and Applications of Mathematics to Security in Cloud Computing: A Case of Addition-Composition Fully Homomorphic Encryption Scheme
(International Journal of Academic Studies, 2016-04-12)Addition-Composition Fully Homomorphic Encryption is given inthis paper to solve data security equation in cloud computation. An earlierattempt to solve security problem has been proposed by Craig Gentry,who combined ... -

Operators with slowly growing resolvents towards the spectrum
(Academic Publications, 1/13/2009)A closed densely defined operator H, on a Banach space X, whose spectrum is contained in R and satisfies (z −H)−1 ≤ c hziα |=z|β ∀ z 6∈ R (0.1) for some α , β ≥ 0; c > 0, is said to be of (α, β)−type R . If instead of (0.1) ... -
Optimal Allocation in Double Sampling for Stratification in the Presence of Nonresponse and Measurement Errors
(International Journal of Statistics and Applied Mathematics, 2019)The present study addresses the problem of minimum cost and precision in the estimation of the population mean in the presence of nonresponse and measurement errors. It is assumed that both the survey variable and the ... -
Optimal Allocation in Small Area Mean Estimation Using Stratified Sampling in the Presence of Non-Response
(International Journal of Statistical Distributions and Applications, 3/12/2021)Sample survey provides reliable current statistics for large areas or sub-population (domains) with large sample sizes. There is a growing demand for reliable small area statistics, however, the sample sizes are too small ... -
An Optimality Analysis of Hiatus Resolution Strategies in Olusuba
(American Research Institute for Policy Development, 2019-06)Vowel hiatus is a prohibited configuration of vowels in many languages of the world. This study is established to examine strategies used to resolve vowel hiatus in Olusuba, a Bantu language spoken in parts of Kenya, ... -
Optimization of ecotourism opportunities within freshwater environments: A multi-criterion planning outline for water-based recreation at Lake Victoria, Kisumu County
(Journal of Natural Sciences Research, 2016)Water-based recreation is an ecotourism genre that attracts participation in most developed countries, but seldom cuts a niche in developed nations. This paper presents synopsis of concepts from a study conducted in four ... -
Option Pricing of an Asset with Seasonal and Periodic Supply
(International Journal of Multidisciplinary Sciences and Engineering, 2014-12-12)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 ... -
Organising Grassroots Infrastructure: The (In)Visible Work of Organizational (In)Completeness
(Urban Studies, 2022-02-01)In this article we build on the concept of incompleteness, as recently developed in both organisational and urban studies, to improve our understanding of the collective actions of grassroots organisations in creating and ... -
