Cellular automata on regular rooted trees [PDF]

, 2012
We study cellular automata on regular rooted trees. This includes the characterization of sofic tree shifts in terms of unrestricted Rabin automata and the decidability of the surjectivity problem for cellular automata between sofic tree ...

Effect of Interactions between Vehicles and Mid-Block Crosswalks on Traffic Flow and CO₂ Emission

Applied Sciences, 2021
Unsignalized mid-block raised crosswalks have been adopted as inclusive transport strategies, providing humps to reduce vehicles’ speed to promote drivers to yield to pedestrians.

Automatic Programming of Cellular Automata and Artificial Neural Networks Guided by Philosophy

, 2020
Many computer models such as cellular automata and artificial neural networks have been developed and successfully applied. However, in some cases, these models might be restrictive on the possible solutions or their solutions might be difficult to ...

A Customizable Quantum-Dot Cellular Automata Building Block for the Synthesis of Classical and Reversible Circuits

The Scientific World Journal, 2015
Quantum-dot cellular automata (QCA) are nanoscale digital logic constructs that use electrons in arrays of quantum dots to carry out binary operations. In this paper, a basic building block for QCA will be proposed.

Silicon Atomic Quantum Dots Enable Beyond-CMOS Electronics

, 2013
We review our recent efforts in building atom-scale quantum-dot cellular automata circuits on a silicon surface. Our building block consists of silicon dangling bond on a H-Si(001) surface, which has been shown to act as a quantum dot.

On the Parity Problem in One-Dimensional Cellular Automata [PDF]

, 2012
We consider the parity problem in one-dimensional, binary, circular cellular automata: if the initial configuration contains an odd number of 1s, the lattice should converge to all 1s; otherwise, it should converge to all 0s.

Cryptographic primitives based on cellular transformations [PDF]

Computer Science Journal of Moldova, 2003
Design of cryptographic primitives based on the concept of cellular automata (CA) is likely to be a promising trend in cryptography. In this paper, the improved method performing data transformations by using invertible cyclic CAs (CCA) is considered ...

Cellular automata and Lyapunov exponents [PDF]

, 2002
In this article we give a new definition of some analog of Lyapunov exponents for cellular automata . Then for a shift ergodic and cellular automaton invariant probability measure we establish an inequality between the entropy of the automaton, the ...
