Algorithms and lower bounds in finite automata size complexity
… the relative succinctness of several types of finite automata, focusing mainly on the following four basic models: one-way deterministic (1)FAs), one-way nondeterministic (1NFAs), two-way deterministic (2DFAS), and two-way nondeterministic (2NFAS). First, we establish the exact values of the …

The transformational implementation of JSD process specifications via finite automata representation
… with reference to formal language theory and automata theory. In particular, it is noted that Jackson structure diagrams are equivalent to regular expressions and can be thought of as specifying corresponding finite automata. The thesis discusses the automatic transformation of structure …

On the power of nondeterminism in small two-way finite automata
… the conjecture that one-way nondeterministic finite automata (NFAS) can be exponentially more succinct than two-way deterministic ones (2DFAS); equivalently, that no polynomial-size sequence of 2DFAs can recognize B, for B a particular sequence of regular languages that is among the hardest of …

On the sets of real vectors recognized by finite automata in multiple bases
This thesis studies the properties of finite automata recognizing sets of real vectors encoded in positional notation using an integer base. We consider both general infinite-word automata, and the restricted class of weak deterministic automata, used, in particular, as symbolic data structures for …

Exploring Computational Models: Analysis, Extensions, and Novel Approaches in Automata Theory
… of classical computational models, including finite automata, pushdown automata, and Turing machines. Motivated by the trade-off between expressive power and structural simplicity, it introduces a novel model called Counter-Based Finite Automata (CBFA). The proposed model extends deterministic …

Expressiveness and Decidability of Weighted Automata and Weighted Logics
Automata theory, one of the main branches of theoretical computer science, established its roots in the middle of the 20th century. One of its most fundamental concepts is that of a finite automaton, a basic yet powerful model of computation. In essence, finite automata provide a method to finitely …

A model-based approach to automated test generation and error localization for Simulink/Stateflow
… to a formal model, called Input/Output Extended Finite Automata (I/O-EFA), that is amenable to formal analysis such as test generation. The approach automatically identifies a set of input-output sequences to activate all executable computations in the Simulink/Stateflow diagram by applying three …

Modelling temporal patterns using soft computing techniques. Application to the analysis of human body movements

Two new approaches for learning Hidden Markov Models
… algorithm that efficiently learns deterministic finite automata. The second insight follows from a careful analysis of the representation of HMMs as matrices and realizing that matrices hold deeper meaning than simply entities used to represent the HMMs. This thesis takes Angluin's approach and …

State Estimation of Timed Discrete Event Systems and Its Applications

Transitive Closure Logic and Multihead Automata with Nested Pebbles
