A penalised data-driven block shrinkage approach to empirical Bayes wavelet estimation [PDF]
, 2010 In this paper we propose a simple Bayesian block wavelet shrinkage method for estimating an unknown function in the presence of Gaussian noise. A data–driven procedure which can adaptively choose the block size and the shrinkage level at each resolution ...

Influence of Root Gap and Tack Weld on Transverse Shrinkage during Welding [PDF]
Welding distortion is caused by the local shrinkage produced during the welding thermal cycle. The local shrinkage can be separated into four components, namely transverse shrinkage, longitudinal shrinkage, transverse bending and longitudinal bending. In

Modeling the Cupping of Lumber
BioResources, 2016 Wood shrinks anisotropically as it loses hygroscopic moisture. While longitudinal shrinkage (parallel to the grain) is nearly negligible in normal wood, transverse shrinkage (across the grain) is significant and characterized as tangential and radial ...

Determination of residual stress evolution during repair welding of high-strength steel components
Forces in Mechanics, 2022 During the assembly of steel structures, unacceptable weld defects may be found. An economical solution is local thermal gouging of the affected areas and re-welding.
