Cesáro-like operators on the Hardy and Bergman spaces of the half plane
(Springer International Publishing, 2016-01-01)
We construct integral operators associated with strongly continuous groups of invertible isometries on the Hardy spaces and the weighted Bergman spaces of the upper half plane. Specifically, we obtain the spectrum and point ...
Norms of Derivations Implemented by S-Universal Operators
(International Journal of Mathematical Analysis, 2011)
Let H be a complex Hilbert space and B(H) the algebra of all
bounded linear operators on H. For A, B ∈ B(H), we define inner
derivations implemented by A,B respectively on B(H) by ΔA(X) =
AX−XA, ΔB(X) = BX−XB and a ...
On the Generalized Reid Inequality and the Numerical Radii
(Applied Mathematical Sciences, 2011)
In this paper, we extend the generalized Reid inequality to include
the numerical radii for the product of two Hilbert space operators.

Groups of isometries associated with automorphisms of the half-plane
(Mississippi State University, 2015)
The study of integral operators on spaces of analytic functions has been considered for the past few decades. However, most of the studies in this line are based on spaces of analytic functions of the unit disc. For the ...
The application of logistic regression in modeling of survival chances of HIV-positive patients under highly active antiretroviral therapy (HAART): A case of Nyakach District …
(Basic Research Journal, 2014)
In Kenya the number of persons requiring antiretroviral Therapy (ART) in 2012 was over 90,000 while globally
more than 1.4 million were under ART in the year 2012. Though ART treatment has decreased mortality of HIV
associated ...
Application of Markov chain to model and forecast stock market trend: A study of Safaricom shares in Nairobi Securities Exchange, Kenya
(International Journal of Current Research, 2015-04-28)
Wealth creation is the goal for every investor. The stock market is one attractive area for investment. Nairobi Securities Exchange being an emerging market in the region, it is considered that both foreign and local ...
Modelling of distribution of the “Matatu” traffic flow using Poisson distribution in a highway in Kenya
(HIKARI Ltd, 2018)
Traffic congestion in urban road and freeway networks leads to strong
degradation of the network infrastructure and accordingly reduced output. Expansion of the available transportation continues to be one of
the solution ...
Statistical trend analysis of residential water demand in Kisumu City, Kenya
(Science Publishing Group, 2015-04-16)
This study sought to analyse trend in the monthly water demand data series in Kisumu city at both seasonal and non-seasonal levels using the parametric method of Ordinary Least Squares (OLS) and non-parametric methods of ...
Modeling trailer-traffic flow on a Kenyan highway
(2014)
Traffic flow modelling is studied in order to ease congestion on roads. However, congestion is also caused by irregular occurrences, such as traffic accidents, poor roads, vehicle disablement, spilled loads and hazardous ...
Norm estimates for convexoid operators
(JOOUST, 2015-06-24)
Hilbert space operators are important in formulation of principles of quantum mechanics and also in other fields of applied sciences. These operators include normal operators, hyponormal operators, normaloid operators, ...
