This paper addresses issues of user interface design, relating to ease of use, of handheld CSCW. In particular, we are concerned with the requirements that arise from situations i...
Scalable parallel computers with TFLOPS (Trillion FLoating Point Operations Per Second) performance levels are now under construction. While we believe TFLOPS processor technology...
In the setting of secure computation, a set of parties wish to securely compute some function of their inputs, in the presence of an adversary. The adversary in question may be st...
