On *Categories of Cohesive, Active Sets and Other Dynamic Systems
… but also to Conway's ""Game of Life"" automaton. Symbolic dynamics of the ""Dining Philosophers"" relational system is computed. A category composed of stochastic matrices is defined and some of its elementary properties are developed. A categorical variant of symbolic dynamics is applied to a …

Dynamical Systems and Matching Symmetry in Beta-Expansions
<p>Symbolic dynamics, and in particular β-expansions, are a ubiquitous tool in studying more complicated dynamical systems. Applications include number theory, fractals, information theory, and data storage.</p> <p>In this thesis we will explore the basics of dynamical systems with a special focus …

Anomaly detection in rolling element bearings via two-dimensional Symbolic Aggregate Approximation
Symbolic dynamics is a current interest in the area of anomaly detection, especially in mechanical systems. Symbolic dynamics reduces the overall dimensionality of system responses while maintaining a high level of robustness to noise. Rolling element bearings are particularly common mechanical …

Omega-Limit Sets of Discrete Dynamical Systems
… new results. We also make extensive use of symbolic dynamics, and prove new results relating to this method of analysis.

CARDIAC AUTONOMIC CONTROL DURING SLEEP IN PATIENTS WITH MULTIPLE SYSTEM ATROPHY: A PILOT STUDY ON THE IMPACT OF CPAP THERAPY
… (MSA) using cardiorespiratory coupling (K2) and symbolic dynamics (0V%, 2UV%, 2LV%) derived from ECG tracings in video‐polysomnography (v‐PSG). The study aims to compare patients with and without sleep‐disordered breathing (SDB) and to assess the acute autonomic effects of CPAP therapy during the …

On the Dynamics of Quasi-Self-Matings of Generalized Starlike Complex Quadratics and the Structure of the Mated Julia Sets
… to a Julia set of a rational map; the dynamics of the two polynomials are reflected in the dynamics of the mated rational map. Here, I investigate the Julia sets of self-matings of generalized starlike quadratic polynomials, which enjoy relatively simple combinatorics. The points in the …

How well can one resolve the state space of a chaotic map?
All physical systems are affected by some noise that limits the resolution that can be attained in partitioning their state space. For chaotic, locally hyperbolic flows, this resolution depends on the interplay of the local stretching/contraction and the smearing due to noise. My goal is to …

Topological Dynamics On Compact Phase Spaces
… recall the necessary background from topological dynamics. We will define the enveloping semigroup and review some of the well known results concerning its structure. Fundamental and well known theorems which lead to the assertion as to the existence of a universal system will be presented. …

Framework for the analysis and design of encryption strategies based on discrete-time chaotic dynamical systems
… the foundations of cryptography, but also of the dynamics and inner structure of chaos. Therefore, any proposal to use chaos in the context of cryptography must respect a series of design rules, in order to avoid the reconstruction of the dynamics of the underlying chaotic system, and to determine …

Algebraic relaxations and hardness results in polynomial optimization and Lyapunov analysis
… Inspired by concepts in automata theory and symbolic dynamics, we define a class of graphs called path-complete graphs, and show that any such graph gives rise to a method for proving stability of switched systems. The semidefinite programs arising from this technique include as special case …

Coloring problems in combinatorics and descriptive set theory
… set theory, with applications to topological dynamics and ergodic theory. This work consists of two parts, each of which is in turn split into a number of chapters. Although the individual chapters are largely independent from each other (with the exception of Chapters 4 and 6, which partially …
