A Bayesian approach to inferring vascular tree structure from 2D imagery
We describe a method for inferring tree-like vascular structures from 2D imagery. A Markov Chain Monte Carlo (MCMC) algorithm is employed to produce approximate samples from the p...

Caches and Hash Trees for Efficient Memory Integrity
We study the hardware cost of implementing hash-tree based verification of untrusted external memory by a high performance processor. This verification could enable applications s...

A Sensitivity Analysis for the Pricing of European Call Options in a Binary Tree Model
The European call option prices have well-known formulae in the Cox-RossRubinstein model [2], depending on the volatility of the underlying asset. Nevertheless it is hard to give ...
