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 ... -
Synthesis, characterization and applications of transition metal-doped manganese oxide catalysts.
(2019)Manganese oxide octahedral molecular sieves exhibit good conductivity, tunable redox properties, high porosity and excellent thermal stability. Thus, these materials have several potential applications as cathodic materials ... -
Design and Implementation of a Transformer Vandalism Monitoring System
(Science Publishing Group, 2018-01-02)Transformer vandalism is becoming an alarming issue in the whole world. Power distribution companies are incurring losses of billions of money due to transformer vandalism. This paper is going to contributes to the design ... -
Performance of Adaptive Bandwidth Allocation for Multimedia Handover Services in UMTS mobile Cellular Networks
(Jommo Kenyatta University of Science and Technology, 2016-05-03)With the ever growing multimedia services in the telecommunicationindustry, Quality of Service (QoS) provisioning in cellular networksis becoming more challenging. Studies have suggested that QoSrequirements can be met by ... -
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 ... -
