Algebraic Methods for Finite Linear Cellular Automata [PDF]

open access: yes, 1996
PhDCellular automata are a simple class of extended dynamical systems which have been much studied in recent years. Linear cellular automata are the class of cellular automata most amenable to algebraic analytic treatments, algebraic techniques are ...

Pseudorandom number generation with self programmable cellular automata [PDF]

open access: yes, 2004
In this paper, we propose a new class of cellular automata – self programming cellular automata (SPCA) with specific application to pseudorandom number generation. By changing a cell's state transition rules in relation to factors such as its neighboring

Fresh-Register Automata [PDF]

open access: yes, 2011
What is a basic automata-theoretic model of computation with names and fresh-name generation? We introduce Fresh-Register Automata (FRA), a new class of automata which operate on an infinite alphabet of names and use a finite number of registers to store

PDA with Independent Counters

open access: yesМоделирование и анализ информационных систем, 2015
Push-down automata with independent counters (PDACs) combine the power of PDAs and Petri Nets. They were developed in [21, 15], as a tool of recognition of languages generated by Categorial Dependency Grammars (CDGs).

A Universal Framework for Analysis of Self-Replication Phenomena

open access: yesEntropy, 2009
In this paper, we propose definitions for a general, domain-independent concept of replicability and specifically focus on the notion of self-replication.

Local Normal Forms for First-Order Logic with Applications to Games and Automata [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 1999
Building on work of Gaifman [Gai82] it is shown that every first-order formula is logically equivalent to a formula of the form ∃ x_1,...,x_l, \forall y, φ where φ is r-local around y, i.e. quantification in φ is restricted to elements of the universe of

Children's engagement and learning in "moving toys" workshops in the 1st cycle of schooling

open access: yesINFAD, 2020
The motivation and interest of children and young people in science areas remains a challenge for contemporary education, and there is also evidence of the importance of its promotion since the early years of schooling as well as the use of ...

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 ...
