This paper proposes a method for optimising the hull form of ocean-going trawlers to decrease resistance and consequently reduce energy consumption. The entire optimisation process was managed by integration computer-aided design computational fluid dynamics (CFD) in CAESES software. Resistance simulated using CFD solver STAR-CCM+. trawler investigated under two main navigation conditions: traw...

Monte Carlo methods are used extensively in computational finance to estimate the price of financial derivative options. In this paper we review the use of quasi-Monte Carlo methods to obtain the same accuracy at a much lower computational cost, and focus on these key ingredients: i) the generation of Sobol and lattice points; ii) reduction of effective dimension using the principal component a...

Flexible DC transmission systems experience negative damping characteristics in the high-frequency range due to delay system control link. This can lead interactions between impedance of modular multilevel converters (MMCs) and AC lines, resulting oscillation (HFO) issues. To resolve this problem, a simplified MMC model was developed, taking into account current inner loop The Sobol method empl...

This study compares the performances of two sampling-based strategies for simultaneous estimation first- and total-order variance-based sensitivity indices (a.k.a. Sobol’ indices). The first strategy corresponds to current approach employed by practitioners recommended in literature. second one was only recently introduced last authors present article. Both rely on different estimators indices....

Due to the limitation of machining accuracy, transmission performance uncertainty mass gears must be evaluated quantitatively provide basis for its application in whole machine. Based on polynomial chaotic expansion (PCE) method, a dynamic analysis method gear systems with specified precision was proposed this paper. Combined tooth surface contact and load-bearing analysis, model system establi...

A supervised machine learning (ML) based computational methodology for the design of particulate multifunctional composite materials with desired thermal conductivity (TC) is presented. The variables are physical descriptors material microstructure that directly link to material’s properties. sufficiently large and uniformly sampled database was generated on Sobol sequence. Microstructures were...
