The $\pi$-Calculus is Behaviourally Complete and Orbit-Finitely Executable [PDF]

open access: yesLogical Methods in Computer Science, 2021
Reactive Turing machines extend classical Turing machines with a facility to model observable interactive behaviour. We call a behaviour (finitely) executable if, and only if, it is equivalent to the behaviour of a (finite) reactive Turing machine.

Some undecidable problems about the trace-subshift associated to a Turing machine [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2015
We consider three problems related to dynamics of one-tape Turing machines: Existence of blocking configurations, surjectivity in the trace, and entropy positiveness. In order to address them, a reversible two-counter machine is simulated by a reversible

How Hard Is It to Detect Surveillance? A Formal Study of Panopticons and Their Detectability Problem

open access: yesCryptography, 2022
The Panopticon (which means “watcher of everything”) is a well-known prison structure of continuous surveillance and discipline studied by Bentham in 1785. Today, where persistent, massive scale, surveillance is immensely facilitated by new technologies,

Quaternionic quantum Turing machines

open access: yesFrontiers in Physics, 2023
Quaternionic quantum theory is an extension of the standard complex quantum theory. Inspired by this, we study the quaternionic quantum computation using quaternions.

Molecular system for an exponentially fast growing programmable synthetic polymer

open access: yesScientific Reports, 2023
In this paper, we demonstrate a molecular system for the first active self-assembly linear DNA polymer that exhibits programmable molecular exponential growth in real time, also the first to implement “internal” parallel insertion that does not rely on ...

A Small Universal Petri Net [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2013
A universal deterministic inhibitor Petri net with 14 places, 29 transitions and 138 arcs was constructed via simulation of Neary and Woods' weakly universal Turing machine with 2 states and 4 symbols; the total time complexity is exponential in the ...

Turing Automata and Graph Machines [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2010
Indexed monoidal algebras are introduced as an equivalent structure for self-dual compact closed categories, and a coherence theorem is proved for the category of such algebras.

Testing technology for tensile properties of metal materials based on deep learning model

open access: yesFrontiers in Neurorobotics, 2022
The properties of metallic materials have been extensively studied, and nowadays the tensile properties testing techniques of metallic materials still have not found a suitable research method.

Reflector – A Dynamic Manifestation of Turing Machines with Time and Space Complexity Analysis

open access: yesJISR on Computing, 2013
The Turing Machine model has proven to be capable of simulating every known computational model. Since its inception the model has served as the basis on which computational devices have been constructed.
