Unfolding of Finite Concurrent Automata [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2018
We consider recognizable trace rewriting systems with level-regular contexts (RTL). A trace language is level-regular if the set of Foata normal forms of its elements is regular. We prove that the rewriting graph of a RTL is word-automatic.

String field theory and brane superpotentials [PDF]

open access: yes, 2001
I discuss tree-level amplitudes in cubic topological string field theory, showing that a certain family of gauge conditions leads to an A-infty algebra of tree-level string products which define a potential describing the dynamics of physical states ...

An Intelligent Fault Analysis and Diagnosis System for Electromagnet Manufacturing Process Based on Fuzzy Fault Tree and Evidence Theory

open access: yesMathematics, 2022
Because an electromagnet has a complex structure and manufacturing process, it is difficult to analyze the overall failure of the electromagnet. In order to solve this problem, a fault intelligent analysis and diagnosis system based on fuzzy fault tree ...

Failure Probability Analysis of Coherent Systems using Intuitionistic Fuzzy Fault Tree Approach [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences
In scenarios where system component failure probabilities are insufficient or imprecise, classical fault tree analysis methods often fail in providing precise assessments of system reliability and safety.

Cosmological Cutting Rules

open access: yesJournal of High Energy Physics, 2021
Primordial perturbations in our universe are believed to have a quantum origin, and can be described by the wavefunction of the universe (or equivalently, cosmological correlators). It follows that these observables must carry the imprint of the founding

MHV gluon scattering in the massive scalar background and celestial OPE

open access: yesJournal of High Energy Physics, 2023
In this paper we study the tree-level OPE between two positive helicity outgoing gluons in the celestial CFT for the Yang-Mills theory chirally coupled to a massive scalar background. This theory breaks the translation as well as scale invariance.

An Energy-Efficient and Fault-Tolerant Convergecast Protocol in Wireless Sensor Networks

open access: yesInternational Journal of Distributed Sensor Networks, 2012
The simple graph theory is commonly employed in wireless sensor networks topology control. An inherent problem of small-granularity algorithms is the high computing complexity and large solution space when managing large-scale WSNs. Computed transmission

Transforming structures by set interpretations [PDF]

open access: yesLogical Methods in Computer Science, 2007
We consider a new kind of interpretation over relational structures: finite sets interpretations. Those interpretations are defined by weak monadic second-order (WMSO) formulas with free set variables.

ForestSoft Set Approach for Estimating Innovation and Entrepreneurship Education in Universities through a Hierarchical and Uncertainty-Aware Analytical Framework [PDF]

open access: yesNeutrosophic Sets and Systems
This study introduces a novel application of ForestSoft Set (FSS) theory, an advanced extension of soft set theory, to evaluate the performance of innovation and entrepreneurship education (IEE) in universities.
