In sheet metal forming processes with complex strain paths, a part is subjected to large plastic deformation. This severe plastic deformation leads to high plastic strain localization zones and subsequent accumulation of those strains. Then internal and superficial micro-defects and in other words ductile damage is created. This damage causes quality problems such as fracture. Therefore, design...

This study investigates the main threats related to environmental degradation that affect Amazonian Indigenous Lands (ILs). Through a cluster analysis, we group ILs according set of common occur within and outside their limits. The results show most 383 are affected internally by combination different threats, namely: deforestation, forest degradation, fires, mining, croplands, pastures, roads....

We implented a lesion segmentation toolkit with a focus on segmenting solid and part-solid lesions from lung CT. The algorithm constructs four three-dimensional features to detect the lung wall, vessels, soft and diffuse tissue and edges. These features form boundaries and propagation zones that guide the evolution of a subsequent shape detection level set. User input is used to determine an in...
