Communicating optimization results
… users of the tool to understand and verify the results that are generated. If a decision-maker has difficulty understanding or trusting the output of a model, then the value of the tool is seriously diminished. This paper examines the challenges between the creators, or operational research …

Rigidity results for thermostats
… structure is absent. We present rigidity results for thermostats that are Anosov, projectively Anosov, or have no conjugate points. For instance, we investigate rigidity under smooth orbit equivalences, and we explain how Eberlein's characterization of Anosov geodesic flows translates to …

Some Results on Crossing Numbers
The drawing of the complete graph in which the vertices are placed on the rims of a cylinder and connected with geodesic edges is conjectured to produce the minimum number of edge crossings for a complete graph, which is its crossing number. This dissertation proves that no edge in this drawing can …

Dynamic friction: measurement and results
… dynamic friction in linear motion and the results obtained using this apparatus. The apparatus consists of a reciprocating platform and a Test Mass on top of it. The platform moves in a sinusoidal pattern with user changeable frequencies and amplitudes. The ultimate objective of the …

New results in extended thermodynamics
… 14 moments case. After that I will present the results of my publications regarding the cases with an arbitrary but fixed number of moments for ideal gases, in the classical and in the relativistic context, and I will also show what happens when we consider their subsystems. Finally it will be …

Clustering of Database Query Results
… to use broad queries to get their desired results. Broad queries often result in too many items forcing the user to spend unnecessary time sifting through these items to find the relevant results. This problem, of finding a desired data item within many items, is referred to as …

Some Almost Sure Convergence Results
The first chapter of the thesis consists of an almost sure invariance principle for random variables in the Domain of Attraction of a Stable Law. Let {Y,Y(,1),Y(,2),...} be a sequence of i.i.d. symmetric random variables with Y in the domain of attraction of X where X is symmetric and stable of …

Some results on symmetric signings
In this work, we investigate several natural computational problems related to identifying symmetric signings of symmetric matrices with specific spectral properties. We show NP-completeness for verifying whether an arbitrary matrix has a symmetric signing that is positive semi-definite, is …

Tilings and other combinatorial results
In this dissertation we treat three tiling problems and three problems in combinatorial geometry, extremal graph theory and sparse Ramsey theory. We first consider tilings of $\mathbb{Z}^n$. In this setting a tile $T$ is just a finite subset of $\mathbb{Z}^n$. We say that $T$ tiles $\mathbb{Z}^n$ …

Halphen's theorem and related results
Halphen's Theorem states that, "A necessary and sufficient condition for every dynamical trajectory in a positional field of force in E3 to be planar is that the field of force is either parallel or central." This result has been known for some time, however only the sufficiency part of the theorem …

CLASSIFICATION RESULTS FOR SEMILINEAR ELLIPTIC EQUATIONS
… focus on the study of symmetry and rigidity results. The thesis is divided into four chapters. In Chapter 1 we consider solutions to some semilinear elliptic equations on complete noncompact Riemannian manifolds and study their classification as well as the effect of their presence on the …

Intractability Results for some Computational Problems
In this thesis, we show results for some well-studied problems from learning theory and combinatorial optimization. Learning Parities under the Uniform Distribution: We study the learnability of parities in the agnostic learning framework of Haussler and Kearns et al. We show that under the uniform …

Some results in non-parametric calibration
In statistical terminology, calibration is the problem of recovering the value of the control variable when the value of the response is given. Mathematically, it is the problem of determining the values ofthe independent variables that respond to a given function value: in other words, the problem …
