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 ... -
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 ... -
Assessment of Water Quality in Boreholes and Wells in Waa Location, Kwale County –Kenya”.
(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 ... -
Norm Estimates for Norm-attainable Elementary Operators
(HIKARI ltd, 2018-03-20)In this paper we estimates the norms of norm-attainable elementary operators: inner derivations, generalized derivation, basic elementary operator and Jordan elementary operator. -
Modeling the Impact of Soil Porosity on Nitrate Leaching to Groundwater Using the Advection Dispersion Equation
(2019-04)Nitrogen is a vital nutrient that enhances plant growth which has motivated the intensive use of nitrogen-based fertilizers to boost crop productivity. However, Pollution by nitrate is a globally growing ... -
On the Norm of Basic Elementary Operator in a Tensor Product
(2018-01)In this paper, we determine the norm of an elementary operator in a tensor product. More precisely, we investigate the bounds of the norm of a basic elementary operator in a tensor product. We employ the techniques of ... -
On The Norm of an Elementary Operator of Finite Length in A C*Algebra”
(2018-08)Properties of elementary operators have been studied over the past years especially the norm aspect. Various results have been obtained on elementary operators of different lengths using different approaches. In this paper, ... -
Stability Analysis of the Modified Advection-Dispersion Model for Nitrate Leaching into Groundwater
(2020)Nitrogen is a vital nutrient that enhances plant growth which has motivated the intensive use of nitrogen-based fertilizers to boost crop productivity. However, Pollution by nitrate is a globally growing problem due to the ... -
