Image Denoising in Mixed Poisson-Gaussian Noise
—We propose a general methodology (PURE-LET) to design and optimize a wide class of transform-domain thresholding algorithms for denoising images corrupted by mixed Poisson–Gau...

Entropy: a consolidation manager for clusters
Clusters provide powerful computing environments, but in practice much of this power goes to waste, due to the static allocation of tasks to nodes, regardless of their changing co...

A Transformational Approach to Constraint Relaxation of a Time-driven Simulation Model
Time-driven simulation models typically model timing in an idealized way that is over-constrained and cannot be directly implemented. In this paper we present a transformation to ...

Inducing Temporal Graphs
We consider the problem of constructing a directed acyclic graph that encodes temporal relations found in a text. The unit of our analysis is a temporal segment, a fragment of tex...
