When designing a system for mobile augmented reality, problems to be tackled concern tracking, rendering performance, end-to-end latency, battery usage, and communication bandwidth of the mobile platform. We developed an integral solution covering all these aspects, while still being manageable from the application's point of view. In this paper we outline the global layout of our system, and d...

Lubrication plays a crucial role in reducing friction for transporting heavy objects, from moving a 60-ton statue in ancient Egypt to relocating a 15,000-ton building in modern society. Although in China spoked wheels appeared ca. 1500 B.C., in the 15th and 16th centuries sliding sledges were still used in transporting huge stones to the Forbidden City in Beijing. We show that an ice lubricatio...
