We present Risk Integrated's Enterprise Spreadsheet Platform (ESP), a technical approach to the near-elimination of spreadsheet risk in the enterprise computing environment, whilst maintaining the full flexibility of spreadsheets for modelling complex financial structures and processes. In its Basic Mode of use, the system comprises a secure and robust centralised spreadsheet management framewo...

Introduction: Risk assessment of hazardous processes is the priority of risk management. Layer of protection analysis (LOPA) is one of the most popular methods used for risk assessment. Due to the insufficient information or uncertainty in failure rates (PFD) of protective layers, risk assessment based on the conventional LOPA can result in error in calculations. In this study, we tried to use ...

Background and aims:  From the 70s onwards, safety engineering made significant progress in developing techniques and regulations relating to the fire. The first, this methods was considered after happening accidents to prevent similar accidents. But with the advancement of technology, the prediction and prevention of fire in complex industries such as power plant finds Important. This study is...

 Coupled-channels Faddeev-Yacubovsky as well as AGS calculations of three-body, J π =0¯ K(NN)I=1(I=1/2) quasibound state in the KNN- πΣ N system were performed in momentum space and the dependence of the three-body energy on the two-body KN- πΣ interaction was investigated.

Accuracy of the radiotherapy requires some routine quality control and dosimetry calculations, which would be done by radiotherapy physicists. Due to the increasing use of computers and simulation software in medical science, as well as trends indicating its continued growth, this study aims to develop a new smart-phone application to perform common radiotherapy-related calculations. Computatio...

Monte Carlo and Active Subspace Identification methods are combined with firstand second-order adjoint sensitivities to perform (forward) uncertainty quantification analysis of the thermo-acoustic stability of two annular combustor configurations. This method is applied to evaluate the risk factor, i.e., the probability for the system to be unstable. It is shown that the adjoint approach reduce...
