Combinatorics of oriented trees and tree-like structures
(Stellenbosch University, 2015)
In this thesis, a number of combinatorial objects are enumerated. Du and Yin as well as Shin and Zeng (by a different approach) proved an elegant formula for the number of labelled trees with respect to a given in degree ...
Locally oriented noncrossing trees
(2015)
We de ne an orientation on the edges of a noncrossing tree induced by the
labels: for a noncrossing tree (i.e., the edges do not cross) with vertices 1; 2; : : : ; n
arranged on a circle in this order, all edges are ...
On the Zero Divisor Graphs of Finite Rings in Which the Product of Any Two Zero Divisors Lies in the Coefficient Subring
(Journal of Mathematics and Statistical Science, 2016)
Let r be a positive integer and 2 ≤ ∈k . Let ( ) kr k GR p p, be a Galois ring of order kr p and
characteristic k p . Consider, ( ) kr k R GR p p U = ,⊕ where U is a finitely generated ( ) kr k GR p p,
module. If Z R( ...
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 ...
Incremental Modernization of Statistics Teaching and Curriculum at Maseno University, Kenya
(International Association of Statistical Education, 2010)
Modernisation of statistics teaching is a continual problem the world over. The advances in
statistical methods and tools along with the growing demand of applied practitioners creates a
dual need of people with the ...
Farmer versus Researcher data collection methodologies: Understanding variations and associated trade-offs
(2019)
The number of non-experts (such as farmers) participating in research activities has increased
over the years, with the aim of them addressing their heterogeneous conditions. The situation
has resulted in them being ...
On the Norm of a Generalized Derivation
(HIKARI Ltd, 2019)
Let H be an infinite dimensional complex Hilbert space and B(H)
the algebra of all bounded linear operators on H. For two bounded
operators A, B ∈ B(H), the map δAB : B(H) → B(H) is a generalized
inner derivation operator ...
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 ...
