Hybrids of equidistribution and Monte Carlo methods of integration can achieve the superior accuracy of the former while allowing the simple error estimation methods of the latter. In particular randomized (0; m; s)-nets in base b produce unbiased estimates of the integral, have a variance that tends to zero faster than 1=n for any square integrable integrand, and have a variance that for nite ...

In the field of sensitivity analysis, Sobol’ indices are widely used to assess importance inputs a model its output. Among methods that estimate these indices, replication procedure is noteworthy for efficient cost. A practical problem how many evaluations must be performed guarantee sufficient precision on estimates. The present paper tackles this issue by rendering iterative. idea enable addi...

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 order to improve both the accuracy and efficiency of grinding slide, this paper designs a novel grinder with dual-lead-dual-head. Since geometric error is one major contributors causing machine inaccuracies, sensitivity analysis performed identify critical terms, an application self-test also given. The volumetric model 38 errors built using homogeneous transformation matrix (HTM) multi-body...
