Three-dimensional finite element modeling of residual stresses in a girth-welded pipe is presented in this paper, with an emphasis on modeling procedures for the global residual stress characteristics. The shell element model with a heat source moving along the circumferential joint is demonstrated to be cost effective and capable of predicting the global residual stress features. Transient res...

A particle system, as understood in computer science, is a novel technique for modeling robots in their environment. Particle systems have traditionally been used for modeling complex dynamics of fluids and gases. In this paper, as the main contribution, we adapt our earlier work on particle systems, to compute a preliminary stress visualization for a bipedal robot walking on a soft sediment. T...

The study was undertaken to estimate the size of the impact of n-3 fatty acids in psychological stress and the extent to which it is mediated via proinflammatory cytokines. Structural equation modeling (SEM) was used to analyze data from 194 healthy Australians. Biomarkers used were erythrocyte polyunsaturated fatty acids (docosahexaenoic acid (DHA) and arachidonic acid (AA)), ex-vivo stimulate...
