Process Mapping for MPI Collective Communications
It is an important problem to map virtual parallel processes to physical processors (or cores) in an optimized way to get scalable performance due to non-uniform communication cost...

Regular layout generation of logically optimized datapaths
The inherent distortion of the structural regularity of VLSI datapaths after logic optimization has until now precluded dense regular layouts of optimized datapaths despite their ...

Rendering on a Budget: A Framework for Time-Critical Rendering
We present a technique for optimizing the rendering of highdepth complexity scenes. Prioritized-Layered Projection (PLP) does this by rendering an estimation of the visible set fo...

Separation and Approximation of Polyhedral Objects
Given a family of disjoint polygons P1, P2, : : :, Pk in the plane, and an integer parameter m, it is NP-complete to decide if the Pi's can be pairwise separated by a polygon...

Pilot optimization for time-delay and channel estimation in OFDM systems
Orthogonal frequency division multiplexing (OFDM) communication systems require accurate estimation of timing offset and channel impulse response in order to achieve desirable per...
