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 ...
Mathematical modeling of HIV/aids co-infection With tuberculosis and pneumonia incorporating protection
(Maseno University, 2016)
The synergistic relationship between HIV/AIDS and respiratory infections, such as tu-
berculosis(TB) and pneumonia not only results in high mortality rates but is also a source
of economic burden borne by many nations ...
A mathematical model for the optimal control Of trypanosomiasis in a cattle population
(Maseno University, 2015)
Trypanosomiasis is a debilitating disease which is a major constraint to livestock production
in sub-Saharan Africa. It leads to loss of productivity in animals and without treatment it is
frequently fatal. The economic ...
Certain properties of essential Numerical ranges of bounded Operators on banach spaces
(Maseno University, 2018)
Abstract
The numerical range of an operator on a Hilbert space has been extensively
researched on. The concept of numerical range of an operator goes back
as early as 1918 when Toeplitz defined it as the field of values ...
Zero Divisor Graphs of Classes of Completely Primary Finite Rings of Maximal Prime Power Characteristic
(Maseno University, 2017)
It is well known that in a finite ring R, every element is either a zero divisor or a unit. The classification of finite rings is not fully settled. Different studies have generated interesting results on certain classes ...
Mathematical model incorporating screening of Immigrants as a control against the spread of Ebola
(Maseno University, 2017)
Characterization Of Scalar Type Operators
(Maseno University, 2017)
A closed densely defined operator H, on a Banach space X, whose spectrum is contained in JR and satisfies the growth condition
II (Z-H)-l II:::; CII~~:l Vz E iJR for some a ~ 0 and C > 0 is of (00,00+1)
type R In studying ...
Construction of Zero Inflated Poisson Mixture Distributions and Application to Fertility Data
(Maseno University, 2018)
In applications involving count data, it is common to encounter the frequency of observed zeros significantly higher than predicted by the model based on the standard
parametric family of discrete distributions. In such ...
Design and Analysis of End Points in Clinical Trials for Visceral Leishmaniasis
(Maseno University, 2015)
Visceral Leishmaniasis (VL) is a vector-borne parasitic disease characterized by fever, substantial weight loss, swelling of the spleen and liver, and
anaemia. Clinical trials in VL generally take long to conclude due to ...
Modeling the Dynamics of Bacteremic Pneumonia: The role of Control Strategies, Case Detection and Treatment
(Maseno University, 2016)
Pneumonia is a respiratory disease mainly caused by bacteria, Streptococcus Pneumoniae. The bacteria exist in up to 90 different strains out of which 25 are invasive.
Pneumonia is one of the leading causes of mortality ...
