Approximations of ruin probabilities under financial constraints.
(Maseno University, 2022)This thesis studies the approximate ruin probabilities under financial constraints which in clude the rate of inflation, constant interest rate, and taxation. When the surplus falls below zero, the insurance company is ... 
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 ... 
Norms of tensor products and elementary Operators
(Maseno university, 2009)In this thesis, we determine the norm of a twosided 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 ... 
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 ... 
Mathematics of Pesticide Adsorption in a Porous Medium: ConvectiveDispersive Transport with steady state water flow In two Dimension
(Maseno university, 2007)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 resulted in ... 
Numerical solution of Kortewegde vries equation
(Maseno university, 2008)The Kottewegde Vrres(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 ... 
On a generalized qnumerical 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 qnumerical range in relation to ... 
Forecasting Kenya’s inflation rate using a Varma for price of imported crude oil and Kenya’s previous inflation rate time series
(Maseno university, 2021)Inflation is the persistent rise in the prices of selected goods and services over time. The rate of inflation measures economic performance of a country and is an important economic indicator to economists of any given ... 
A correlation study on the effect of Nonconditional cash transfer on poverty Alleviation among older persons in Emuhaya sub county, Kenya
(Maseno university, 2021)The world is experiencing growth in the number of older persons with those aged 60 years and above projected to double from 1.4 billion in 2015 to 2.8 billion in 2050. According to the Kenya Population and Housing Census, ... 
Mathematical modelling of flood Wave: a case study of Budalang'i Flood plain basin in Busia county, Kenya
(Maseno university, 2022)Flooding is a worldwide problem with more adverse e ects in developing countries. In Kenya, severe ooding is experienced on the lower tributaries of Lake Victoria, mainly Budalang'i area. This is indicated in the ... 
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 ... 
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 ... 
Mathematical model for nonlinear stock price adjustment
(Maseno university, 2010)The field of financial mathematics has drawn a lot of interest from both practitioners and academicians since the derivation of Black Scholes model of 1970s. :Ihe celebrated option pricing formula, the socalled Black ... 
Simplifying the markov chain analysis of rainfall Data using genstat
(Maseno university, 2011)Despite the rapid development of statistical packages, a lot of climatic data still remain unanalyzed due to lack of specialized routines in most of the packages, One package has a climatic menu though with limitation ... 
Deterministic modelling of tuberculosis and Hiv/aids
(Maseno university, 2010)The human immunodeficiency virus (HIV) pandemic presents ~ massive challenge to the control of recurrent diseases like tuberculosis (TB) at all levels. Tuberculosis is also one of the most common causes of morbidity and ... 
Efficiencies of reinforced bib and augmented· Block designs in sugarcane test families’ vs Controls experiments
(Maseno university, 2010)The designs used for experimentation generally require making all the possible paired comparisons among the treatments but in plant breeding selection programmes the comparison of interest is usually a subset of all the ... 
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. ... 
Nonparametric 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 ... 
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 ... 
Match Analysis of HIV/AIDS Model With Reference to Kenya
(Maseno University, 2011)Epidemiology models are used to combine complex data from various sources in order to study equally complex outcomes. The first simple HIV/AIDS epidemic model was by Anderson in 1986. Since then a lot has been done in ...
