On Characterization of u-ideals determined by sequences’’
(2013)The area of ideals is important in the study of Analysis, algebra, Geometry and Computer science. The various types of ideals have been studied, for example m ideals and h ideals. The m ideals defined on real Banach spaces ... -
Unconditional Banach Space Ideal Property’’
(Scientific Advances Publishers, 2012)Abstract Let Lw ′ denote the assignment which associates with each pair of Banach spaces X , Y , the vector space Lw ′ ( X , Y ) and K ( X , Y ) be the space of all compact linear operators from X to Y. Let T ∈ Lw ′ ( X ... -
Magnetic field and hall current effect on Mud free convection flow past a vertical rotating flat plate
(2012-11)In this study, effects of Hall current and rotation on an electrically conducting rarefied gas are investigated . A constant , strong magnetic field is applied at an angle φ to both the electric field and the ... -
On Almost Similarity Operator Equivalence Relation
(2013-06)We consider the almost similarity property which is a new class in operator theory and was first introduced by A. A. S. Jibril. We establish that almost similarity is an equivalence relation. Some results on almost similarity ... -
Rapid, Economical and selective Compexometric Determination of Iron (III) in its synthetic alloys using 3 hydroxy-3- phynyl-1-(2,4,6-tribromophynyl)
(2013-09)The present study describes a simple, selective, rapid and economical method for the determination of iron (III) in its synthetic alloys using 3-hydroxy -3- phenyl-1- (2,4,6- tribro mophenyl) triazene as ... -
``Transitivity Action of An(n=5,6,7,8) On Unordered and Ordered Pairs’’
(2013-09)In this paper, we study some transitivity action properties of the alternating group 𝐴𝑛(𝑛=5,6,7 ,8) acting on unordered and ordered pairs from the set 𝑋𝑋 = {1,2,…,𝑛𝑛} through determination of the number of disjoint ... -
Suborbital Graphs and their properties for unordered pairs in An(n=5,6,7,8) through rank and subdegrees determination’’
(2013-12-18)In this paper, through computation of the rank and subdegrees of alternating group ( =5,6,7) on unordered triples we construct the suborbital graphs corresponding to the suborbits of these triples. When ( ≥ 5) acts on ... -
Application of Banach space ideal properties in image transmission over wireless network
(2014-04)The Banach space operator ideals and nuclear maps have a large class of morphisms which behave as if they were part of a compact closed category, that is, they allow one to transfer variables between the domain and the ... -
Distribution of Spectrum in a Direct Sum Decomposition of Operators into Normal and Completely Non normal parts;
(Modern Scientific Press Company, Florida, USA, 2014-09-05)We discuss the distribution of spectra of a direct sum decomposition of an arbitrary operator into normal and completely non normal parts. We utilize the fact that any given operator 𝑇∈𝐵(𝐻) can be ... -
A note on quasi-similarity of operators in Hilbert spaces
(2015-01)In this paper we introduce the notion of Quasi-similarity of bounded linear operators in Hilbert Spaces. We do so by defining a quasi-affinity from one Hilbert Space H to K. Some results on quasi-affinities are also ... -
Analysis of Volatility of Real Exchange Rate and Exports in Kenya using the Garch Model: 2005:2012
(2015-07)The real exchange rate has proven to be an important factor in international trade because it is expected that exports respond to real exchange rate movements with respect to the characteristics of the importing ... -
Modeling and Forecasting Kenyan GDP Using Autoregressive Integrated Moving Average (ARIMA) Models
(2016-04-13)The Gross Domestic Product (GDP) is the market value of all goods and services produced within the borders of a nation in a year. In this paper, Kenya's annual GDP data obtained from the Kenya National Bureau of statistics ... -
An Empirical analysis of Commercialization of Small holder Farming: Its inclusive household Welfare Effects
(2916-04-18)This paper assesses the potential impact of commercialization of agriculture on household welfare of farmers in eastern Kenya under the Mwea rice scheme. The study consists of cross-sectional data collected with structured ... -
Modeling HIV/AIDS Co Infection with Malaria and Tuberculosis: The role of treatment and counseling
(2018-05)HIV/AIDS remains one of the leading causes of death in the world with its effects most devastating in Sub Saharan Africa due to its dual infection with opportunistic infections especially malaria and tuberculosis. This ... -
On Almost Similarity and Metric Equivalence of operators. Accepted for publication
(2016-06)In this paper, we investigate almost-similarity relation, metric equivalence and other relations of operators on Hilbert spaces. We characterize almost-similar, metrically equivalent operators. Roughly speaking, we consider ... -
On Analytical Approach to Semi-open/Semi-closed sets in Metric Spaces”
(Science Publishing Group, 2017-03-03)The concept of open and closed sets has been extensively discussed on both metric and topological spaces. Various properties of these sets have been proved under the underlying spaces. However, scanty literature is available ... -

(CODEN (USA), 2017)Water from boreholes and dug wells is extensively used in Kwale County, especially by rural communities living away from established market centers, where piped water is commonly available. The study aimed ... -
Metric Equivalence as an Almost Similarity Property
(Science Research Organization, 2017-11-03)Various results that relate to almost similarity and other classes of operators such as isometry, normal, unitary and compact operators have been extensively discussed. It has been shown that if ... -
