Provable, Secure & Democratic Election Model
(INTERNATIONAL JOURNAL OF MULTIDISCIPLINARY SCIENCES AND ENGINEERING, 2017)Democracy is founded on the principle of elections and opinion expression capabilities. Bimber & Leggewie foresaw e-democracy. Voting is an information transfer model. Trust is essential to communication channel but ... -
Reachability in complete t-ary trees
(Annals of Mathematics and Computer Science, 2023-10-01)Mathematical trees such as Cayley trees, plane trees, binary trees, noncrossing trees, t-ary trees among others have been studied extensively. Reachability of vertices as a statistic has been studied in Cayley trees, plane ... -
Reachability results in labelled t-ary trees
(Open Journal of Mathematical Sciences, 2021)In this paper, we prove some new formulas in the enumeration of labelled t-ary trees by path lengths. We treat trees having their edges oriented from a vertex of lower label towards a vertex of higher label. Among other ... -
Recursive Relation for Zero In ated Poisson Mixture Distributions
(2017)The paper extends the work of Sarguta who derived recursive re- lations for univariate distributions by considering the ZIP continuous mixtures. The paper gives a recursive formular which can be used to evaluate the mixed ... -
Refined enumeration of 2-noncrossing trees
(Academic Publishing House, 2021)A 2-noncrossing tree is a connected graph without cycles that can be drawn in the plane with its vertices on the boundary of circle such that the edges are straight line segments that do not cross and all the vertices ... -
Refined enumeration of k-plane trees and k-noncrossing trees
(2022)A k-plane tree is a plane tree whose vertices are assigned labels between 1 and k in such a way that the sum of the labels along any edge is no greater than k+1. These trees are known to be related to (k+1)-ary trees, and ... -
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. Mathematics Subject Classi cation: 47A10; 47A05; 47A53 -
Spatial Comparison and Quality Check of Farmer-recorded Daily Rainfall Data; A Case of Nyakach and Soyain-sigowett, Ken
(Science Publishing Group, 2020-09-01)Abstract: 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 ... -
Spectra of Composition Groups on the Weighted Dirichlet Space of the Upper Half-Plane
(Springer, 2020)We prove that the group of weighted composition operators induced by contin uous automorphism groups of the upper half plane U is strongly continuous on the weighted Dirichlet space of U, Dα(U). Further, we investigate ... -
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 ... -
A STUDY OF ATTITUDES OF TEACHERS AND PUPILS TOWARD THE TEACHING AND LEARNING Of M~THEMATICS RESPECTIVELY IN UPPER PRIMARY SCHOOLS IN MASIMBA EDUCATIONAL ZONE, IRIANYI DIVISION, KISII DISTRICT (KENYA) •
(University of Kenyatta., 1986)The purpose of the study was to identify the attitudes held by the primary school teachers and pupils toward the teaching and learning of Mathematics respectively. The study was done at Masimba Educational zone, Irianyi ... -
Three Dimensional Mathematical Models for ConvectiveDispersive Flow of Pesticides in Porous Media
(IJESC, 2018)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 ... -
Various notions of orthogonality in normed spaces
(Elsevier, 2013-09-01)In this paper, we present various notions and aspects of orthogonality in normed spaces. Characterizations and generalizations of orthogonality are also considered. Results on orthogonality of the range and the kernel of ... -
Velocity Profile for Magnetohydrodynamic Flow in Straight Horizontal Elliptical Pipe
(Applied Mathematical Sciences, 2021)Velocity profile for Magnetohydrodynamic (MHD) fluid flow in a straight long pipe with elliptical cross section has been investigated. Governing equations are partial differential equations comprising Ohm’s law of ... -
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 ...
