Ensuring spatio-temporal access control for real-world applications
Traditional access control models, such as Role-Based Access Control (RBAC), do not take into account contextual information, such as location and time, for making access decision...

A Probabilistic Framework for Partial Intrinsic Symmetries in Geometric Data
In this paper, we present a novel algorithm for partial intrinsic symmetry detection in 3D geometry. Unlike previous work, our algorithm is based on a conceptually simple and st...
