Quantification of Temporal Fault Trees Based on Fuzzy Set Theory [PDF]

open access: yes, 2014
Fault tree analysis (FTA) has been modified in different ways to make it capable of performing quantitative and qualitative safety analysis with temporal gates, thereby overcoming its limitation in capturing sequential failure behaviour. However, for many systems, it is often very difficult to have exact failure rates of components due to increased ...

From Proof Nets to the Free *-Autonomous Category [PDF]

open access: yesLogical Methods in Computer Science, 2006
In the first part of this paper we present a theory of proof nets for full multiplicative linear logic, including the two units. It naturally extends the well-known theory of unit-free multiplicative proof nets.

On the VC-dimension‎, ‎covering and separating properties of the cycle and spanning tree hypergraphs of graphs [PDF]

open access: yesTransactions on Combinatorics, 2022
In this paper‎, ‎we delve into studying some relations between the structure of the cycles and spanning trees of a graph through the lens of its cycle and spanning tree hypergraphs which are hypergraphs with the edge set of the graph as their vertices ...

On the regularization of extremal three-point functions involving giant gravitons

open access: yesPhysics Letters B, 2015
In the AdS5/CFT4 set-up, extremal three-point functions involving two giant 1/2 BPS gravitons and one point-like 1/2 BPS graviton, when calculated using semi-classical string theory methods, match the corresponding three-point functions obtained in the ...

Failure Analysis for Hydraulic System of Heavy-Duty Machine Tool with Incomplete Failure Data

open access: yesApplied Sciences, 2021
A hydraulic system is a key subsystem of heavy-duty machine tools with a high failure intensity, the failure of which often causes shutdown of production and economic loss in machining. Therefore, it is necessary to implement failure analysis to identify

Chiral fermions and gauge-fixing in five-dimensional theories [PDF]

open access: yes, 2001
We study in detail the issue of gauge-fixing in theories with one universal extra dimension, i.e. theories where both bosons and fermions display Kaluza-Klein (KK) excitations.

Multi-decision tree prediction model for coal seam floor water inrush based on cost-sensitive theory

open access: yesGong-kuang zidonghua, 2020
When predicting coal seam floor water inrush, the situation is generally divided into two states: safe state and water inrush state. The state data has non-equilibrium characteristics.

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.

Binary classification based on a combination of rough set theory and decision trees

open access: yesINNOVATIVE TECHNOLOGIES AND SCIENTIFIC SOLUTIONS FOR INDUSTRIES, 2023
The subject of the study is to improve the accuracy and efficiency of classification algorithms using decision trees by integrating the principles of Rough Set theory, a mathematical approach to approximating sets. The aim of the study is to develop a hybrid model that integrates rough set theory with decision tree algorithms, thereby solving the ...

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 ...
