Spectral analysis of certain groups of isometries on Hardy and Bergman spaces
(Academic Press, 2017-12-15)
Using the similarity theory of semigroups as well as spectral theory, we obtain the resolvents of the generators of strongly continuous groups of isometries on the Hardy and Bergman spaces. These groups are obtained as ...
Some Properties of the Essential Numerical Range on Banach Spaces
(HIKARI Ltd,, 2017)
We study the properties of the essential algebraic numerical range as
well as the essential spatial numerical range for Banach space operators.

Weighted Composition Groups on the Little Bloch Space
(Hindawi, 2020-04-29)
We determine both the semigroup and spectral properties of a group of weighted composition operators on the little Bloch space. It turns out that these are strongly continuous groups of invertible isometries on the Bloch ...
4-Regular prime graphs of nonsolvable groups
(CORNELL UNIVERSITY, 2019-01-11)
Let G be a finite group and cd(G) denote the character degree
set for G. The prime graph ∆(G) is a simple graph whose vertex set consists
of prime divisors of elements in cd(G), denoted ρ(G). Two primes p, q ∈
ρ(G) are ...
Consistency Inference Property of QIC in Selecting the True Working Correlation Structure for Generalized Estimating Equations
(Science Publishing Group, 2019-06-29)
The generalized estimating equations (GEE) is one of the statistical approaches for the analysis of longitudinal data with correlated response. A working correlation structure for the repeated measures of the outcome ...
Spatial Comparison and Quality Check of Farmer-recorded Daily Rainfall Data; A Case of Nyakach and Soin-sigowett, Kenya
(Science Publishing Group, 2020-01-09)
Small scale farming is currently still heavily dependent on rainfall in developing nations. With the challenge of climate change, many innovations are proposed to help the farmers mitigate and adapt. The use of historical ...
Inference Properties of QIC in the Selection of Covariates for Generalized Estimating Equations
(HIKARI Ltd, 2019)
The Quasi-likelihood information criterion (QIC)which results from
utilizing Kullbacks I-divergence as the targeted discrepancy is widely
used in the GEE framework to select the best correlation structure and
the best ...
A Probabilistic Estimation of the Basic Reproduction Number: A Case of Control Strategy of Pneumonia
(cience Publishing Group, 2014)
Deterministic models have been used in the past to understand the epidemiology of infectious diseases, most importantly to estimate the basic reproduction number, Ro by using disease parameters. However, the approach ...
Fitting Time-series Models to Kisumu Rainfall Data for the Period 1961-2014
(Science Publishing Group, 2020-02-20)
Many small-scale farmers require adequate forecasts to help them plan for the rainfall. The National Meteorological Service provides forecasts seasonally, monthly and weekly. The forecasts are qualitative in nature hence ...
