We introduce an efficient, robust means of obtaining reliable surface descriptions, suitable for object recognition, at multiple scales from range data. Mean and Gaussian curvatures are used to segment the surface into regions of four saliency classes, each based on curvature consistency. We evaluate curvature consistency in a robust multivoting scheme. Contiguous regions consistent in both mea...

An important question in information processing is the extent to which neural .ring patterns remain consistent while processing representations. Transient changes in representational consistency can provide clues to the dynamics of neural processing. We present a generalized framework for measuring the consistency of a neuronal representation that does not require explicit knowledge of the para...

The reliability and availability of replicated data can often be increased by generating new replicas when some become inaccessible due to system malfunctions. This technique has been used in the Regeneration Algorithm, a replica control protocol based on file regeneration. The read and write availabilities of replicated data managed by the Regeneration Algorithm are evaluated and two new regen...

Strategyproof mechanisms provide robust equilibrium with minimal assumptions about knowledge and rationality but can be unachievable in combination with other desirable properties such as budget-balance, stability against deviations by coalitions, and computational tractability. In the search for maximally-strategyproof mechanisms that simultaneously satisfy other desirable properties, we intro...
