Opacity light fields: interactive rendering of surface light fields with view-dependent opacity
We present new hardware-accelerated techniques for rendering surface light fields with opacity hulls that allow for interactive visualization of objects that have complex reflec...

Optimization-Based Virtual Surface Contact Manipulation at Force Control Rates
Previous interactive works have used springs, heuristics, and dynamics for surface placement applications. We present an analytical technique for kilohertz rate manipulation of CA...

Floorplan area minimization using Lagrangian relaxation
modules can be handled in constraint graphs efficiently. This Floorplan area minimization is an important problem because many modules have shape flexibilities during the floorplan...

New Public-Key Cryptosystem Using Braid Groups
Abstract. The braid groups are infinite non-commutative groups naturally arising from geometric braids. The aim of this article is twofold. One is to show that the braid groups ca...
