In this research, two different filler metals, ERNiCrMo-3 and ER309L, were used for developing different microstructure, austenite (γ) and austenite and ferrite (γ+δ) in the weld metal and fatigue properties of welded samples were evaluated in the air and sea water environments. Microstructural studies indicated a good agreement between predicted microstructures via schiffler diagram and metall...

In this study, fatigue test and crack propagation analysis of welded joints in ships and offshore structures were performed. The test models have two types of welded joints, T-joint and double plate. Test data is presented in S-N curves obtained by the Hot Spot Stress (HSS) approach. The S-N data for each length of crack were appraised to define the fatigue life of crack initiation and propagat...

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
