Norms of tensor products and elementary Operators
(Maseno university, 2009)In this thesis, we determine the norm of a two-sided symmetric operator in an algebra. More precisely, .we investigate the lower bound of the operator using the injective tensor norm. Further, we determine the norm of ... -
Numerical Computation of Steady Buoyancy Driven MHD Heat and Mass Transfer Past An Inclined Infinite Flat Plate with Sinusoidal Surface Boundary Conditions
(2007)In this paper we study the e ects of magnetohydrodynamics (MHD) uid ow on a two dimensional boundary layer ow of a steady free convection heat and mass transfer on an inclined plate in which the angle of inclination ... -
Numerical solution of Korteweg-de vries equation
(Maseno university, 2008)The Kotteweg-de Vrr-es(KdV)is a mathematical model of waves on shallow water surfaces. The mathematical theory behind the KdV equation is rich and interesting, and, in the broad sense, is a topic of active mathematical ... -
Numerical Solutions of Burgers Equation Using Hybrid Methods
(Maseno University, 2016)Research on Burgers equation: u_t + 〖uu〗_x = 〖αu〗_xx which is a second order nonlinear partial differential equation is gaining interest for its application and mathematics itself. It arises in model studies of turbulence ... -
Nurses’ knowledge related to pain assessment for critically ill patients at a public sector Hospital in Johannesburg
(University of the Witwatersrand, Johannesburg, 2014)Discrepancies exist between how pain is assessed in ICU patients able and unable to self report. There are pain assessment scales and guidelines that have been developed over the years for pain assessment. However, ... -
Occurrence and Antimicrobial Profiles of Salmonella Sp in Fish (Oreochromis Niloticus) and Selected Fish-Ponds in Western Kenya
(Maseno University, 2011)Salmonella, a gram-negative facultative rod shaped bacterium: '--'in the family Enterebacteriaceae, is found in the intestinal tracts of humans and animals. Salmonella causes salmonellosis, which manifests as two diseases ... -
Occurrence, genetic relatedness and effects of diplostomum(digenea: diplostomidae) species in oreochromis niloticus L. and distribution among Vector snails in Kibos area
(Maseno University, 2013)Diplostomum species metacercariae, are trematodes that pose economic threat to aquaculture globally. Despite their diversity, species identification is difficult owing to their striking morphological similarities. Poor ... -
On a generalized q-numerical Range
(Maseno university, 2008)We 'consider numerical ranges of a bounded linear operator on complex Hilbert spaces. Many properties of the classical numerical range are known. We investigate the properties of the q-numerical range in relation to ... -
On completely bounded Operators
(2010)Calculating norms of matrices when the entries are not constants is the first problem tackled in this thesis. We have considered the space of matrices with entries from the algebra of bounded linear operators and ... -
On completely positive maps
(Maseno University, 2015)Completely positive maps is an important field due to its significance, application and mathematics itself. While discussing the properties of the positive maps, researchers have questioned whether the properties of the ... -
On Joint Essential Numerical Ranges
(Maseno University, 2013)The concept of numerical range on a Hilbert space was first introduced by O. Toeplitz in 1918 for matrices. This notion was independently ex tended by G. Lumer and F. Bauer in the sixties on finite dimensional Banach ... -
On norms of a derivation
(Maseno university, 2010)The study of derivations still remains an area of interest to mathematicians today. Of special attention has been the study of norms of inner derivations. Most of the work in this area is based on Stampfli's result of ... -
On norms of elementary operators
(2009)The study of elementary operators has been of great interest to many mathematicians for the past two decades. Of special interest has been to determine the norms of these operators. The norm problem for elementary operators ... -
On Schwarz norms
(Maseno University, 2015)Abstract Investigation of the properties of the numerical radius by Berger and Stampfli showed that indeed numerical radius norm is a Schwarz norm. Later on James P.Williams determined a family of distinct Schwarz norms ... -
On shifted Fibonacci sequences and Their polynomials
(Maseno University, 2020)Fibonacci sequences and their polynomials have been generalized mainly by two ways: by maintaining the recurrence relation and varying the initial conditions and by varying the recurrence relation and maintaining the ... -
On The Algebraic Numerical Range of the Basic Elementary Operator and Norm of a Generalized Derivation
(Maseno University, 2020)An elementary operator is a bounded linear map defined on the set of bounded linear operators acting on an infinite dimensional complex Hilbert space H. Various forms of elementary operators have been studied in the past ... -

(Maseno University, 2009)The design and application of solar chimney and solar pressure-staged wind tunnel electric power generating plants involve the understanding of parameters which affect their operations and utilization. The size and ... -
On the Essential Numerical Range
(Maseno University, 2013)The convexity. closure and compactness of the numerical range among other properties constitute a considerable literature in operator theory. The properties of the essential numerical range and how they are related to ... -
On the numerical ranges and Spectra of normal operators
(Maseno university, 2010)The study of numerical ranges and spectra has been of great interest to many mathematicians in the past decades. In this study, we have continued to look at the numerical ranges and spectra of operators .on a Hilbert space. ... -
Operation of mutation on Polar quivers
(Maseno university, 2009)In recent times, there has been a lot of interest in the study of quivers, both by mathematicians and theoretical physicists. We introduce a new concept of polar quivers and their mutation. The idea of polar quivers arises ...
