#### Information and Estimation Theoretic Approaches to Data Privacy

Warner [145] in 1960s proposed a simple mechanism, now referred to as the randomized response model, as a remedy for what he termed “evasive answer bias” in survey sampling. The randomized response setting is as follows: ...

#### Management and Sensing of Spectrum in Cognitive Radio

(2013-06-04)

Under the contemporary spectrum usage regulations, radio frequency bands are allocated statically to licensed users in a large geographical area and over a long period of time. Recent investigations have revealed that such ...

#### Variations of Li's criterion for an extension of the Selberg class

(2012-08-09)

In 1997, Xian-Jin Li gave an equivalence to the classical Riemann hypothesis,
now referred to as Li's criterion, in terms of the non-negativity of a particular
infinite sequence of real numbers. We formulate the analogue ...

#### An impulsive differential equation model for Marek's disease

(2016-09-22)

Many dynamical processes are subject to abrupt changes in state. Often these perturbations can be periodic and of short duration relative to the evolving process. These types of phenomena are described well by what are ...

#### Curves of low genus on surfaces and applications to Diophantine problems

(2015-08-31)

We describe in detail a technique due to Vojta for finding the explicit set of curves of low genus on certain algebraic surfaces of general type, and refine some of its aspects. We then provide applications of this method ...

#### On the role of regularity in mathematical control theory

(2016-04-08)

In this thesis, we develop a coherent framework for
studying time-varying vector fields of different regularity classes and their flows. This setting has the benefit of unifying all classes of regularity. In particular, ...

#### On the Convergence and Applications of Mean Shift Type Algorithms

(2013-10-01)

Mean shift (MS) and subspace constrained mean shift (SCMS) algorithms are non-parametric, iterative methods to find a representation of a high dimensional data set on a principal curve or surface embedded in a high ...

#### Homoclinic Points in the Composition of Two Reflections

(2013-09-17)

We examine a class of planar area preserving mappings and give a geometric condition that guarantees the existence of homoclinic points. To be more precise, let $f,g:R \to R$ be $C^1$ functions with domain all of $R$. ...

#### Joint Modelling of Longitudinal Quality of Life Measurements and Survival Data in Cancer Clinical Trials

(2013-01-23)

In cancer clinical trials, longitudinal Quality of Life (QoL)
measurements on a patient may be analyzed by classical linear
mixed models but some patients may drop out of study due to
recurrence or death, which causes ...

#### Smooth Complete Intersections with Positive-Definite Intersection Form

(2012-10-16)

We classify the smooth complete intersections with positive-definite intersection form on their middle cohomology. There are two families. The first family are quadric hypersurfaces in P(4k+1) with k a positive integer. ...
