Secure Physical Auctions for the Non-Expert
(2014)An auction is a simple way of selling and buying goods. Modern auction protocols often rely on complex cryptographic operations to ensure manifold security properties, for instance bidder-anonymity or bid-privacy, non-repudiation, fairness or public veriability of the result. This makes them dicult to understand for users who are not experts in cryptography. We propose two physical auction protocols inspired by Sako's cryptographic auction ...Report -
Consistently Orienting Facets in Polygon Meshes by Minimizing the Dirichlet Energy of Generalized Winding Numbers
(2014)Jacobson et al. [JKSH13] hypothesized that the local coherency of the generalized winding number function proposed in that work could be used to correctly determine consistent facet orientations in polygon meshes. We report on an approach to consistently orienting facets in polygon meshes by minimizing the Dirichlet energy of generalized winding numbers. While the energy can be concisely formulated and eciently computed, we found that ...Report -
