This paper introduces a new shape matching algorithm for computing correspondences between 3D surfaces that have undergone (approximately) isometric deformations. The approach makes two main contributions: First, the is, unlike previous work, robust to "topological noise" such as large holes or "false connections", which is both observed frequently in real-world scanner data. Second, our samples space of feasible solutions uncertainty can be detected explicitly. We employ novel randomized...

Many businesses and private households rely on Free Libre Open Source Software (FLOSS). Due to a lack of sustained contributors, however, most FLOSS projects do not survive. The early identification developers who are likely remain is thus an eminent challenge for the management initiatives. Previous research has shown that individuals' subjective assessment often inaccurate emphasizing need objectively evaluate retention behavior. Consistent with concepts Person-Job (P-J) Person-Team (P-T)...
