The Intersection Problem for Steiner Triple Systems
(2011-11-16)
In this thesis we give a new solution to the intersection problem for Steiner triple systems, using results that were not available when the original solution was given. In particular we show for each pair (n,k), where n ...
Finitely Generated Modules Over Noncommutative Chain Rings
(2011-10-26)
The notion of a right chain ring, a ring whose lattice of right ideals is linearly ordered by inclusion, is a generalization of a valuation ring. In this work we investigate properties of right chain rings and the structure ...
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 ...
Spatial Spread Dynamics of Monostable Equations in Spatially Locally Inhomogeneous Media with Temporal Periodicity
(2013-05-31)
This dissertation is devoted to the study of semilinear dispersal evolution equations.
These type of equations are called as Monostable or KPP type equations, which arise
in modeling the population dynamics of many ...
Semi-Supervised Classification Techniques in Big Data Text Analytics
(2013-04-22)
Imagine that you are trying to read everything you got in 2011 as soon as possible. That will take the first three months of 2012. How can we get access to the vast unstructured literature, automatically process it, ...
Topics in Edge Regular Graphs
(2014-07-24)
A graph, G, is edge-regular with parameters (n,d,lambda) if G is regular of degree d on n vertices and for all u, v in V(G) such that uv is in E(G), the order of the intersection of N(u) and N(v) is lambda, where N(v) ...
An example of movable approximations of a minimal set in a continuous flow
(2009-02-23)
In the present dissertation the study of flows on n-manifolds in particular in dimension three, e.g., R^3, is motivated by the following question. Let A be a compact invariant set in a flow on X. Does every neighbourhood ...
Poroelasticity
(2009-02-23)
Poroelasticity is the study of elastic deformation of porous materials saturated with a fluid and the coupling between the fluid pressure and the solid deformation.
Considerable progress has been made in formulating ...
New Classes of Multivariate Gamma Survival and Reliability Models
(2008-09-09)
Multivariate modeling and analysis based on the multivariate normal distribution is well established and widely used. However, when the marginal distributions have only a positive support, such as time-to-event models, ...
Torsionless Modules and Minimal Generating Sets for Ideals of Integral Domains
(2008-09-09)
This is a treatise of relationships between the number of elements necessary to generate the ideals of a domain and the
torsionless modules of that domain. Three types of domains are
identified according to natural ...
