Event tree analysis is widely used for reliability and safety analyses as it can be used to specify how the system behaves under various failure conditions. Even though event tree analysis is automated, the construction of event trees is unfortunately manual, and thus error-prone. This paper proposes an automated technique to generate event trees from scenario specifications even before system ...

Event anaphora resolution plays a critical role in discourse analysis. This paper proposes a tree kernel-based framework for event pronoun resolution. In particular, a new tree expansion scheme is introduced to automatically determine a proper parse tree structure for event pronoun resolution by considering various kinds of competitive information related with the anaphor and the antecedent can...

Abstract: Event tree is a logical analysis of probability for outcome events by initiating event and probable subsequent events. However, the evaluation of every single event may contain vague information or cannot be described by a crisp number of probabilities in application. So this paper aims to develop an event tree by using fuzzy set theory with a combination of triangle membership functi...

This paper presents a methodology for quantitative risk analysis for offshore installations, that incorporates both technical and operational conditions. The basic building blocks of the methodology are barrier block diagrams, event trees, fault trees, and influence diagrams. Barrier block diagrams are used to illustrate the event scenarios and the effect of barrier systems on the scenarios. Ev...

We present efficient methods for Brillouin zone integration with a non-zero but possibly very small broadening factor $\eta$, focusing on cases in which downfolded Hamiltonians can be evaluated efficiently using Wannier interpolation. describe robust, high-order accurate algorithms automating convergence to user-specified error tolerance $\varepsilon$, emphasizing an computational scaling respe...

PSA tries to assess the whole spectrum of risk presented by a hazardous plant or operation. It does this by systematically modelling a great number of different accident sequences. The main cause of possible public or environmental harm from an accident in a nuclear plant is the radioactive release that may result, so PSA attempts to assess the frequency of occurrence of the whole range of such...
