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.

Zigzags in Turing Machines [PDF]

open access: yes, 2010
We study one-head machines through symbolic and topological dynamics. In particular, a subshift is associated to the subshift, and we are interested in its complexity in terms of realtime recognition. We emphasize the class of one-head machines whose subshift can be recognized by a deterministic pushdown automaton.

The Ghost in the Quantum Turing Machine [PDF]

open access: yesThe Once and Future Turing, 2013
In honor of Alan Turing's hundredth birthday, I unwisely set out some thoughts about one of Turing's obsessions throughout his life, the question of physics and free will. I focus relatively narrowly on a notion that I call "Knightian freedom": a certain

Local Transition Functions of Quantum Turing Machines [PDF]

open access: yes, 2000
Foundations of the notion of quantum Turing machines are investigated. According to Deutsch's formulation, the time evolution of a quantum Turing machine is to be determined by the local transition function.

Undecidability and Complexity for Super-Turing Models of Computation

open access: yesProceedings, 2022
It seems that intelligent complex systems will require formalisms having richer behavior than Turing machines. Very little is known about the relations (e.g., the expressiveness and/or effectiveness) between new super-Turing models of computation.

Formalizing Turing Machines [PDF]

open access: yes, 2012
We discuss the formalization, in the Matita Theorem Prover, of a few, basic results on Turing Machines, up to the existence of a (certified) Universal Machine. The work is meant to be a preliminary step towards the creation of a formal repository in Complexity Theory, and is a small piece in our Reverse Complexity program, aiming to a comfortable ...

Addressing Machines as models of lambda-calculus [PDF]

open access: yesLogical Methods in Computer Science, 2022
Turing machines and register machines have been used for decades in theoretical computer science as abstract models of computation. Also the $\lambda$-calculus has played a central role in this domain as it allows to focus on the notion of functional ...

Set Turing Machines

open access: yesCoRR, 2021
We define a generalization of the Turing machine that computes on general sets. Our main theorem states that the class of generalized Turing machine computable functions and the class of Set Recursive functions coincide.

Going beyond Church–Turing Thesis Boundaries: Digital Genes, Digital Neurons and the Future of AI

open access: yesProceedings, 2020
The Church–Turing thesis deals with computing functions that are described by a list of formal, mathematical rules or sequences of event-driven actions such as modeling, simulation, business workflows, etc.
