Network Modelling of Infectious Diseases
(Maseno University, 2014)Mathematical modelling of infectious diseases is an important tool for assessing disease dynamics. This branch of mathematics has provided many significant insights concerning the epidemiology of infectious diseases. ... -
Ngero as a social object
(University of Nairobi, 1978)This is a study of the art of rig r no v/hich is a genre of Luo oral literature. The terra ncoro is in the singular. Like1 some Luo words whose singulars end in ro, the two let tors are replaced by che in the plural ... -
Non-parametric regression estimation of a finite Population total in the presence of Heteroscedasticity
(Maseno university, 2010)Non parametric regression provides computationally intensive estimation.of unknown finite population quantities. Such estimation is usually more flexible and robust than inferences tied to design - probabilities (in ... -
Norms of elementary operators
(Maseno University, 2015)Properties of elementary operators have been investigated in the recent past under a variety of aspects. Their norms have been a subject of interest for research in operator theory. Specifically, deriving a formula to ... -

Norms of elementary operators.
(Maseno university, 2010)The norm of an elementary operator has been investigated over long period by several mathematician under various special circumstances. Timoney working on algebra of bounded linear operators on Hilbert spaces, established ... -
Norms of generalized derivations on norm ideals
(Maseno University, 2019)The norms of inner and generalized derivations on different kinds of algebras have been determined. However, the norms of their restrictions to norm ideals have not been fully explored. For instance, the concept of ... -
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 ...
