Discrete-event system abstractions for on-line logical and real-time hierarchical control
Published 2016“…The problem is addressed by formulating, for a reference output set, a new abstraction concept for output control feasibility of a DES modeled by a Moore automaton, and a system decomposition of a Moore automaton with a natural output control structure into a controllable subsystem and an uncontrollable subsystem. …”

A coalgebraic take on regular and $\omega$-regular behaviours
Published 2021-12-01“…The second part of the paper focuses on presenting the concepts of a (coalgebraic) automaton and its ($\omega$-) behaviour. We end the paper with coalgebraic Kleene-type theorems for ($\omega$-) regular input. …”

Quasitriangular Structure of Myhill–Nerode Bialgebras
Published 2012-07-01“…In computer science the Myhill–Nerode Theorem states that a set L of words in a finite alphabet is accepted by a finite automaton if and only if the equivalence relation ∼L, defined as x ∼L y if and only if xz ∈ L exactly when yz ∈ L, ∀z, has finite index. …”

Irreducible compositions of degree two polynomials over finite fields have regular structure
Published 2018“…In this paper we prove that D has a natural regular structure by showing that there exists a finite automaton having D as accepted language. Our method is constructive.…”

Transformations Between Different Types of Unranked Bottom-Up Tree Automata
Published 2010-08-01“…The bottom-up computation of an unranked tree automaton may be either deterministic or nondeterministic, and further variants arise depending on whether the horizontal string languages defining the transitions are represented by a DFA or an NFA. …”

A minimalist model of characteristic earthquakes
Published 2002-01-01“…In a spirit akin to the sandpile model of self-organized criticality, we present a simple statistical model of the cellular-automaton type which simulates the role of an asperity in the dynamics of a one-dimensional fault. …”

An Event Based Semantics of P Systems
Published 2008-12-01“…In this paper we propose a translation of membrane system into zero safe nets and then we show how to associate an event automaton to the 1-unfolding of these nets. Thus we propose an event based view of computations of a membrane system.…”

Polynomial automata: zeroness and applications
Published 2017“…We introduce a generalisation of weighted automata over a field, called polynomial automata, and we analyse the complexity of the Zeroness Problem in this model, that is, whether a given automaton outputs zero on all words. While this problem is non-primitive recursive in general, we highlight a subclass of polynomial automata for which the Zeroness Problem is primitive recursive. …”

Finite Automata with Generalized Acceptance Criteria
Published 2001-01-01“…We examine the power of nondeterministic finite automata with acceptance of an input word defined by a leaf language, i.e., a condition on the sequence of leaves in the automaton's computation tree. We study leaf languages either taken from one of the classes of the Chomsky hierarchy, or taken from a time- or space-bounded complexity class. …”
