Functional safety fault tree analysis of a model autonomous haulage system
… is accomplished by developing a generic fault tree to define exposures and failure modes of an AHS. Representative scenarios simulating various mining environments and situations are utilized to define the typical exposures in an AHS deployment. Through the implementation of a systematic safety …

A search for the ttH (H → bb) channel at the Large Hadron Collider with the ATLAS detector using a matrix element method
A matrix element method analysis of the Standard Model Higgs boson, produced in association with two top quarks decaying to the lepton-plus-jets channel is presented. Based on 20.3 fb−1 of √s=8 TeV data, produced at the Large Hadron Collider and collected by the ATLAS detector, this analysis …

UAS Risk Analysis using Bayesian Belief Networks: An Application to the VirginiaTech ESPAARO
… to investigate alternative methods of failure analysis. This thesis proposes a method of expanding on the Fault Tree Analysis (FTA) method to a Bayesian Belief Network (BBN) model. FTA is demonstrated to be a special case of BBN and BBN can allow for more complex interactions between nodes than …

Advanced Quantitative Risk Assessment of Offshore Gas Pipeline Systems
… of aggregative risk assessment and fault tree analysis are developed. Aggregative risk assessment is to evaluate the risk levels of components, subsystems, and the overall OGSS. Fault trees are then used to represent the cause-effect relationships for a specific risk in the system. Use of …

Probabilistic risk assessment of system-level radiation effects
System-level radiation effects analysis is performed using a time-dependent Probabilistic Risk Assessment (PRA) methodology. Data-driven models for the expected behavior of radiation-sensitive parts are instanced in a system model for Fault Tree Analysis (FTA). The system model is then solved using …
