Radiometric Calibration by Transform Invariant Low-rank Structure
We present a robust radiometric calibration method that capitalizes on the transform invariant low-rank structure of sensor irradiances recorded from a static scene with different...

Optimizing MPI collective communication by orthogonal structures
Many parallel applications from scientific computing use MPI collective communication operations to collect or distribute data. Since the execution times of these communication op...

Adjacency queries in dynamic sparse graphs
We deal with the problem of maintaining a dynamic graph so that queries of the form “is there an edge between u and v?” are processed fast. We consider graphs of bounded arbor...

Kinetic Dictionaries: How to Shoot a Moving Target
A kinetic dictionary is a data structure for storing a set S of continuously moving points on the real line, such that at any time we can quickly determine for a given query point ...

Timing optimization by bit-level arithmetic transformations
This paper describes a method to optimize the performance of data paths. It is based on bit-level arithmetic transformations, and is especially suited to optimize large adder stru...
