Abstract:
This article extensively examines several sampling strategies, emphasising probability and non-probability sampling approaches. Sampling is essential in research as it influences the degree to which research findings accurately represent and can be applied to a larger population. This article provides a definition of probability sampling and explores its different approaches. The text highlights the benefits of probability sampling, such as its capacity to guarantee impartial selection and facilitate statistical inference. Furthermore, this article delves into the constraints and factors to be

The probability of default and the default time are simulated using Monte Carlo and the number of scenarios needed to obtain convergence in the simulations is investigated.

Next the concept of hypoellipticity is used to show that the corresponding Fokker-Planck equation of the highly degenerate diffusion is we

Abstract:
Abstract The reliability of a structure under random dynamic load could be measured by estimating the probability of its response, e.g., a stress element or a node displacement, passing a threshold. Such analyses often require time domain simulation, especially for nonlinear systems. For systems with high reliability with a probability of failure less than 10−4, if Monte Carlo simulation (MCS) is used, an enormous number of replications must be completed which becomes impractical for real-life structures. Variance reduction techniques such as Importance Sampling (IS) or other methods such as S

Abstract:
In 1988, the U.S. Nuclear Regulatory Commission (NRC) issued a revision to 10CFR50.46 which allows realistic calculations for loss-of-coolant accident/emergency core cooling system (ECCS) analysis. The revision also requires that uncertainties in the analysis method and inputs be considered, such that there is a high level of probability that the ECCS criteria would not be exceeded. Currently, two methodologies are approved by the U.S. Nuclear Regulatory Commission for such calculations. One technique relies on response surface generation and applying Monte-Carlo technique to the regression mo
