Virtual Contact: the Continuum from Purely Visual to Purely Physical

Providing appropriate cues to users when interacting with objects in immersive virtual environments (IVEs) is a difficult task. In addition to individual user differences, environmental factors, and task-specific requirements, the technological complexity of the current state of the art in haptic feedback further increases the difficulty. Though the technology continues to improve, we are still...

Purely Rational Secret Sharing

Rational secret sharing is a fundamental primitive at the intersection of cryptography and game theory. In essence, a dealer wishes to engineer a communication game that, when rationally played, guarantees that each of the players learns the dealer’s secret. Yet, all solutions so far were quite inefficient and relied on the players’ beliefs and not just on their rationality. After providing a m...

Purely elastic flow asymmetries.

Using a numerical technique we demonstrate that the flow of the simplest differential viscoelastic fluid model (i.e., the upper-convected Maxwell model) goes through a bifurcation to a steady asymmetric state when flowing in a perfectly symmetric "cross-slot" geometry. We show that this asymmetry is purely elastic in nature and that the effect of inertia is a stabilizing one. Our results are in...

Purely functional data structures

When a C programmer needs an efficient data structure for a particular problem, he or she can often simply look one up in any of a number of good textbooks or handbooks. Unfortunately, programmers in functional languages such as Standard ML or Haskell do not have this luxury. Although some data structures designed for imperative languages such as C can be quite easily adapted to a functional se...
