Title:

Digital Tape Drawing

Abstract:

Tape drawing artists at auto design studios create concept images of cars using black photographic tape. These images eventually have to be digitized. Researchers at Alias/Wavefront have come up with a digital version of tape drawing. In this presentation I will talk about a paper presented at UIST '99 titled "Digital Tape Drawing". The authors are Ravin Balakrishnan, George Fitzmaurice, Gordon Kurtenbach and William Buxton.

9. Seminars

• Wednesday, 26 April 2000, 3:30PM - Computer Science (Algorithms and Complexity Group), DC1304
  Michael A. Nielsen: -- Quantum computation and quantum information
  Quantum computers are devices which harness quantum mechanics to perform information processing tasks in a manner strikingly different from and perhaps superior to "classical" computing devices. Most interestingly, they appear to be good candidates to violate the strong Church-Turing thesis: that any realisitic computing device can be simulated efficiently using a probabilistic Turing machine. In this talk I introduce the basic ideas of quantum computation, describe some of the reasons why quantum computers are thought to be superior to ordinary computing devices, and review some of the challenges facing us in understanding the power of quantum computers for information processing. No prior knowledge of quantum mechanics will be assumed.
• Thursday, 27 April 2000, 10:30AM - Computer Science , DC 1304
  N. Asokan: -- Fair Exchange
  In this talk, I will describe optimistic_ protocols for fair exchange. They use a third party to guarantee fairness; but the third party is involved only when one of the players demands it. The idea is to optimise for the common case that both players are honest and are interested in completing the exchange successfully. I will illustrate the optimistic approach using contract signing protocols in the synchronous communication model (where communication channels can be assumed to be reliable) as well as the asynchronous communication model.
• Thursday, April 27, 3:00 - 5:00 p.m., DC 1304.
