3-Cycle Systems and Structure within Graph Decompositions
(2014-07-24)
An $H$-decomposition of a graph $G$ is a partition of the edge set $E(G)$ such that each element of the partition induces a subgraph isomorphic to $H$. A packing or cover of $\lambda K_n$ (with triples) is an ordered pair ...
4-cycles systems of line graphs of complete multipartite graphs
(2008-08-15)
Here we investigate the necessary and sufficient conditions for the existence of 4 - cycle systems of the line graphs of complete multipartite graphs.
5-cycle systems
(2014-04-25)
A k-cycle system of a multigraph G is an ordered pair (V,C) where V is the vertex set of G and C is a set of k-cycles, the edges of which partition the edges of G. A k-cycle system of lambda K_v is known as a lambda-fold ...
A-Stability For Two Species Competition Diffusion Systems
(2006-08-15)
My dissertation research focuses on establishing the structural
stability of the attractor ($\mathcal{A}$-stability) via Morse-Smale
property for diffusive two-species competition systems
\begin{equation}
\label{abst ...
Adjoint Orbits of Borel Subgroup on Maximal Nilpotent Subalgebra of Types A and C.
(2021-11-18)
We describe the adjoint orbits of a Borel subgroup on a maximal nilpotent algebra of Types A and C.
In Chapter 1, we provide a historical background and motivation behind the study. We highlight the
important works in ...
Advanced Neuroscience Data Analysis using Functional Data Analysis Methods
(2023-12-06)
There has been a growing interest in neuroscience data, encompassing fields like engineering, bioengineering, and neurophysiology. Researchers increasingly utilize neural signals, including electroencephalography (EEG) ...
Advanced Statistical Learning Approaches to Healthcare
(2019-06-03)
In this dissertation, we propose a novel statistical modeling methodology that effectively analyzes and extracts information from large datasets. Two real datasets were employed to validate the proposed methodology: breast ...
Almost Resolvable Maximum Packings of Complete Bipartite Graphs with 4-Cycles
(2012-07-17)
A packing of a complete bipartite graph K(m,n) with 4-cycles is a decomposition of K(m,n) into a collection C of edge-disjoint 4-cycles and a set of unused edges L referred to as the leave. If C is as large as possible ...
Amalgamations and Detachments of Graphs and Hypergraphs
(2012-07-09)
A \textit{detachment} of a graph $H$ is a graph obtained from $H$ by splitting some or all of its vertices into more than one vertex. If $g$ is a function from $V(H)$ into $\mathbb {N}$, then a \textit{$g$-detachment} of ...
Analysis and finite element approximation for nonlinear problems in poroelasticity and bioconvection
(2013-04-23)
This dissertation is concerned with nonlinear systems of partial differential equation with solution dependent physical coefficients satisfying the Nemytskii assumption. Such equations arise from two important application ...
Analysis and Optimal control of deterministic Vector-Borne diseases model
(2018-07-18)
In this dissertation, two systems of deterministic differential equations are introduced to study the transmission of vector-borne diseases between a host and a vector. The total population of the host and the vector are ...
An Analysis of Item Response Theory
(2019-07-02)
This paper examines a field of psychological and educational measurement testing theory
called Item Response Theory. The paper delves into the basics of the theory, its theoretical
and statistical background, and discusses ...
Analysis of stochastic vector-host epidemic models
(2017-07-25)
In this dissertation, deterministic and stochastic mathematical models are proposed to study vector-host epidemic models with direct transmission. The total population of the host and the vector is divided into different ...
The Application of Complex Numbers and Quaternions in Navigation
(2020-11-30)
Complex numbers and quaternions have a wide array of applications. This paper beginsby briefly going over the history of complex numbers and quaternions, bringing up little knownfacts on main discoverers. Then, we ...
Applications of Stationary Sets in Set Theoretic Topology
(2010-11-10)
The notion of a stationary subset of a regular cardinal, a set which intersects any closed unbounded subset of that cardinal, is a useful tool in investigating certain properties of topological spaces. In this paper we ...
Applications of Stochastic Gradient Descent for Optimization of Complex Systems with Uncertainty
(2021-07-27)
The Stochastic Gradient Descent (SGD) method in all its variations has gained popularity with the recent progress in Machine learning. In this dissertation we implement and analyze two modifications of the SGD method. In ...

(2016-12-09)
In the 1950s, G. G Lorentz introduced the spaces $\Lambda(\alpha)$ and $M(\alpha)$, for $0<\alpha<1$ and showed that the dual of $\Lambda(\alpha)$ is equivalent to $M(\alpha)$ in his paper titled 'Some New Functional ...
Avoiding k-Rainbow Graphs in Edge Colorings of Kn and other Families of Graphs
(2024-04-26)
A simple graph, G, avoids a k-rainbow edge coloring if any color appears on at least k + 1 edges of G. For any positive integer k, the k-Anti-Ramsey Number, ARk(G,H), is the maximum number of colors in an edge coloring of ...
