Computational determination of inner stresses in rock masses

M.E. Díaz‐Fernández, C. González‐Nicieza, M.I. Álvarez‐Fernández, A.E. Álvarez‐Vigil, A. Argüelles Amado

This paper aims to present a computational approach which – setting off from measures obtained by using an overdrilling method – determines, automatically and accurately, stress…

Detecting the sensitivity of structural damage based on the Hilbert‐Huang transform approach

Wei‐Ling Chiang, Dung‐Jiang Chiou, Cheng‐Wu Chen, Jhy‐Pyng Tang, Wen‐Ko Hsu, Te‐Yu Liu

This study aims to investigate the relationship between structural damage and sensitivity indices using the Hilbert‐Huang transform (HHT) method.

Neurocomputing strategies for solving reliability‐robust design optimization problems

Nikos D. Lagaros, Vagelis Plevris, Manolis Papadrakakis

This paper, by taking randomness and uncertainty of structural systems into account aims to implement a combined reliability‐based robust design optimization (RRDO) formulation…

Stochastic sensitivity analysis using preconditioning approach

R. Chowdhury, S. Adhikari

High‐dimensional model representation (HDMR) is a general set of quantitative model assessment and analysis tools for capturing the high‐dimensional relationships between sets of…

A novel image denoising algorithm in wavelet domain using total variation and grey theory

Hong‐jun Li, Zhi‐min Zhao, Xiao‐lei Yu

The traditional total variation (TV) models in wavelet domain use thresholding directly in coefficients selection and show that Gibbs' phenomenon exists. However, the nonzero…

A new approach for prediction of the stability of soil and rock slopes

Alireza Ahangar‐Asr, Asaad Faramarzi, Akbar A. Javadi

Analysis of stability of slopes has been the subject of many research works in the past decades. Prediction of stability of slopes is of great importance in many civil engineering…
