Abstract. The present study focuses on identifying the parameters from Weather Research and Forecasting (WRF) model that strongly influence simulation of tropical cyclones over Bay Bengal (BoB) region. Three global sensitivity analysis (SA) methods, namely, Morris One-at-A-Time (MOAT), multivariate adaptive regression splines (MARS), surrogate-based Sobol', are employed to identify most sensiti...

In Rijeka of the 1950s professor Drago Vrbanić was well-known as an excellent gynaecologist and surgeon, especially in the field of gynaecological malignant tumours. He headed the gynaecological and radiology departments of the Sobol Brothers General Hospital, and successfully applied several radiotherapy methods. Later in the 1960s, he introduced modern classification of tumours and multidisci...

We try to understand the various components affecting the stability of tunneling and wellbore operations. We use a series of advanced finite element (FE) simulations to obtain a dataset which contains the stress response of the soil during drilling operations as a function of 12 input parameters. Using Multivariate Adaptive Regression Splines (MARS), we create a simplified model of the simulati...

Quasi Monte Carlo simulations are built on quasi random number generator (QRNG). Even if the use of a QRNG might lead to a faster convergence, for example with Monte Carlo integral computation, most of the simulation time can be taken by the number generation part. This paper present an optimization technique, called “unrolling” applied to QRNG. It consists in the generation and storage of rand...

This paper presents an efficient sampling-based algorithm for the estimation of the upper bounds of the total sensitivity indices. These upper bounds, introduced by Sobol’, are based on the integration of the classical (local) gradient sensitivity analysis within the whole parameter space of the inputs. Hence, in this work the idea is to repeat the estimation of the local sensitivity analysis a...
