A likelihood ratio test for correlated paired multivariate samples
(Chilean Statistical Society, 2020-04)Many laboratory experiments in the fields of biological sciences usually involve two main groups say the healthy and infected subjects. In one of these kind of experiments, each specimen from each group can be divided ... -
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 ... -
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 ... -
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 ... -

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 ... -
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 ... -
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. -
Norm- Attainability of Generalized Finite Operators on C*- Algebra
(Modern Scientific Press Company, 2022)Norm -attainability of elementary operators on Hilbert and Banach spaces have been Characterized by many mathematicians. However, there is little information on Normattainability of generalized finite operators on C*-algebra. ... -
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 ... -
A NOTE ON QUASI-SIMILARITY OF OPERATORS IN HILBERT SPACES
(International Journal of Mathematical Archive, 2015-07-23)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 ... -
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 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 ... -
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 ... -
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 ... -
On Similarity and Quasisimilarity equivalence relations
(2012-01)Similarity and unitary equivalence can be shown to be of equivalence relations. We discuss a result showing that two similar operators have equal spectra (i.e. point and approximate point spectrum). More ... -
On the Banach Space Numerical Range for a Linear Operator ",
(Modern Scientific Press Company, Florida, USA, 2019-03-25)The numerical range has been studied extensively in Hilbert spaces. Properties of the numerical range such as non-emptiness, containment of the spectrum and in particular, convexity have been proved and results have ... -
On The Convexity of A Generalized q-Numerical Range’’
(2005-01)For a given $q in kom$ with $|q| le 1$, we study the $C$-numerical range of a Hilbert space operator where $C$ is an operator of the form [ left( begin{array}{ccc} qI_n & sqrt{1-|q|^2}I_n \ 0_n & 0_n end{array} right) oplus ... -
