Guided play: from instructions to creativity when constructing automata

open access: yesINFAD, 2020
Play is a very important activity for children development and there are evidences that it can be an added value when used for educational purposes. Research about how to integrate play in education points to the importance of teacher role, namely how ...

Beyond Language Equivalence on Visibly Pushdown Automata [PDF]

open access: yes, 2009
We study (bi)simulation-like preorder/equivalence checking on the class of visibly pushdown automata and its natural subclasses visibly BPA (Basic Process Algebra) and visibly one-counter automata. We describe generic methods for proving complexity upper

A Combined Syntactical and Statistical Approach for R Peak Detection in Real-Time Long-Term Heart Rate Variability Analysis

open access: yesAlgorithms, 2018
Long-term heart rate variability (HRV) analysis is useful as a noninvasive technique for autonomic nervous system activity assessment. It provides a method for assessing many physiological and pathological factors that modulate the normal heartbeat.

CANA: A Python Package for Quantifying Control and Canalization in Boolean Networks

open access: yesFrontiers in Physiology, 2018
Logical models offer a simple but powerful means to understand the complex dynamics of biochemical regulation, without the need to estimate kinetic parameters.

Reliability and Safety of Autonomous Systems Based on Semantic Modelling for Self-Certification

open access: yesRobotics, 2021
A novel modelling paradigm for online diagnostics and prognostics for autonomous systems is presented. A model for the autonomous system being diagnosed is designed using a logic-based formalism. The model supports the run-time ability to verify that the

Les illustrations en pleine page du cartulaire du XIIe siècle (ms 210 d’Avranches), problèmes d’interprétation et sources textuelles

open access: yesTabularia, 2021
The three large images that adorn folios 4v, 19v and 25v of the 12th-century cartulary have already been extensively studied and commented upon and continue to raise numerous problems of interpretation.

LR Parsing for LCFRS

open access: yesAlgorithms, 2016
LR parsing is a popular parsing strategy for variants of Context-Free Grammar (CFG). It has also been used for mildly context-sensitive formalisms, such as Tree-Adjoining Grammar.

Probabilistic Timed Automata with Clock-Dependent Probabilities [PDF]

open access: yes, 2017
Probabilistic timed automata are classical timed automata extended with discrete probability distributions over edges. We introduce clock-dependent probabilistic timed automata, a variant of probabilistic timed automata in which transition probabilities ...

Tessellation Automata

open access: yesInformation and Control, 1969
Certain mathematical studies of pattern recognition, evolution theories, and self-reproducing automata motivated the definition of the tessellation automaton which is a mathematical model of an infinite array of uniformly interconnected identical finite-state machines.

BOUNDED PARIKH AUTOMATA [PDF]

open access: yesInternational Journal of Foundations of Computer Science, 2011
The Parikh finite word automaton model (PA) was introduced and studied by Klaedtke and Rueß. Here, we present some expressiveness properties of a restriction of the deterministic affine PA recently introduced, and use them as a tool to show that the bounded languages recognized by PA are the same as those recognized by deterministic PA. Moreover, this
