Heat Flow and a Faster Algorithm to Compute the Surface Area of a Convex Body
We draw on the observation that the amount of heat diffusing outside of a heated body in a short period of time is proportional to its surface area, to design a simple algorithm f...

Chaos in a Simple Cellular Automaton Model of a Uniform Society
In this work we study the collective behavior in a model of a simplified homogeneous society. Each agent is modeled as a binary “perceptron”, receiving neighbors’ opinions a...

Managing Multi-Mode Tasks with Time Cost and Quality Levels using Optimal Discrete Control Synthesis
Real-time control systems are complex to design, and automation support is important. We are interested in systems with multiple tasks, each with multiple modes, implementing a fu...

Occlusion Textures for Plausible Soft Shadows*
Authors' version: This paper presents a novel approach to obtain plausible soft shadows for complex dynamic scenes and a rectangular light source. We estimate the lights occl...
