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 ... -
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 ... -
Computation of efficient nash equilibria for experimental economic games
(Maseno University, 2014)Game theory has been used to study a wide variety of human and animal behaviors. It looks for states of equilibrium, sometimes called solutions. Nash equilibrium is the central solution concept with diverse applications ... -
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 ... -
The Derivation of a Logistic Nonlinear Black Scholes Merton Partial Differential Equation: European Option
(Maseno University, 2011)\onlinear Black-Scholes equations have been increasingly attracting interest over the last twenty years. This is because they provide more accurate values by taking into account more realistic assumptions, such as ... -
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 ... -
Determinants of mortality and survival time among HIV infected patients on antiretroviral therapy in Machakos county, Kenya
(Maseno University, 2019)ABSTRACT Human Immunodeficiency Virus (HIV) remains one of the world's most significant public health concerns. Anti-retroviral treatment (ART) is meant to suppress replication of the virus, consequently improving health ... -
Finite element method solution for steady magnetohydrodynamic flow in a straight horizontal pipe of elliptical cross section
(Maseno University, 2022)Velocity profile and temperature distribution for Magnetohydrodynamic (MHD) flow in a straight horizontal pipe of elliptical cross section has been investigated. Many researchers have carried out research on pipes of circular, ... -
Health risk of toxic Cyanobacteria in drinking water in the Nyanza gulf water, Lake Victoria Kenya
(Maseno University, 2018)Cyanobacteria are single-celled algae that thrive in warm and nutrient rich water bodies including lakes. They can produce different kinds of toxins called cyanotoxins. Microcystin is the most common and most studied ... -
Lie symmetry solutions of the Generalized burgers equation
(Maseno University, 2005)Burgers equation: u, + UUx = luxx is a nonlinear partial differential equation which arises in model studies of turbulence and shock wave theory. In physical application of shock waves in fluids, coefficient 1 ,has the ... -
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 ... -

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 ... -
Mathematical Modeling of Pesticide Adsorption In A Porous Medium; Convection-Dispersion Transport with Steady State Water Flow in Three Dimensions
(Maseno University, 2019)ABSTRACT The transport of solutes through porous media where chemicals undergo adsorption or change process on the surface of the porous materials has been a subject of research over years. Usage of pesticides has ... -
Mathematical Models for Malaria Co-Infections With Persistent Pediatric Infections in Kenya
(Maseno University, 2013)Despite many years of study and advanced biological, medical and mathematical understanding of diseases together with commitment to child survival, malaria and persistent infectious diseases of childhood continue 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 ... -
Modeling the effects of interference in fertility rate: a case study of Rwanda, Indonesia and Kenya
(Maseno University, 2016)Many studies have been done on fertility for many years. However, very little has been documented in the existing literature concerning modeling of fertility in the presence of interference, yet interference to fertility ... -
Modelling The Impact of Misdiagnosis and Treatment on the Dynamics of Malaria Concurrent and Co-Infection with Pneumonia and Typhoid
(Maseno University, 2014)Mathematical models of malaria-pneumonia and malaria- typhoid concurrent and co-infection have been formulated to establish the effects of misdiagnosing pneumonia and typhoid as malaria. We performed stability analysis ... -
