A Novel Dynamic Approach for Risk Analysis and Simulation Using Multi-Agents Model

Applied Sciences, 2022
Static risk analysis techniques (SRATs) use event graphs and risk analysis assessment models. Those techniques are not time-based techniques and hence are inadequate to model dynamic stochastic systems.

Fault Diagnosis of Roadheader Based on Dynamic Fault Tree

DEStech Transactions on Engineering and Technology Research, 2017
The roadheader faults are highly concerned by machinery factories. Facing the variety of the roadheader faults, the complex relationships between fault sources, as well as the difficulties of fault diagnosis, this paper proposed a method to set up the dynamic fault tree of roadheader.

Reliability analysis of dynamic systems by translating temporal fault trees into Bayesian networks [PDF]

, 2014
Classical combinatorial fault trees can be used to assess combinations of failures but are unable to capture sequences of faults, which are important in complex dynamic systems.

Make Bow-tie Dynamic by Rethinking It as a Hierarchical Bayesian Network. Dynamic Risk Assessment of an Lng Bunkering Operation

Chemical Engineering Transactions, 2022
In the present era, the spread of cyber-physical systems in the framework of the so-called Industry 4.0, is leading towards a complete automation of industrial processes, which are increasingly decentralized, smart, and require fewer and fewer frontline ...

Multi-step ahead direct prediction for machine condition prognosis using regression trees and neuro-fuzzy systems

, 2009
This paper presents an approach to predict the operating conditions of machine based on classification and regression trees (CART) and adaptive neuro-fuzzy inference system (ANFIS) in association with direct prediction strategy for multi-step ahead ...

Uncertainty-Aware Dynamic Reliability Analysis Framework for Complex Systems

IEEE Access, 2018
Critical technological systems exhibit complex dynamic characteristics such as time-dependent behavior, functional dependencies among events, sequencing and priority of causes that may alter the effects of failure.

Data-driven approach to machine condition prognosis using least square regression trees

, 2009
Machine fault prognosis techniques have been profoundly considered in the recent time due to their substantial profit for reducing unexpected faults or unscheduled maintenance.

Quantitative evaluation of Pandora Temporal Fault Trees via Petri Nets [PDF]

, 2015
© 2015, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd. All rights reserved. Using classical combinatorial fault trees, analysts are able to assess the effects of combinations of failures on system behaviour but are unable ...

Heterozygous loss‐of‐function alleles associate the conserved 3′‐5′ exoribonuclease EXOSC10 with hypersensitivity to the anticancer drug 5‐fluorouracil

Molecular Oncology, EarlyView.
EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

Risk-based Interventions for Safer Operation of a Hydrogen Station

Chemical Engineering Transactions, 2017
In ensuring safety of plant operation, both the reliability of plant components and human resources are important. Moving towards optimising resources, there is a need to prioritise intervention measures such as maintenance program and review of standard
