Optic-Flow Information Extraction with Directional Gaussian-Derivatives
This work is intended to give some ideas to extract motion information from an image sequence. A directional energy is defined in terms of the 1-D Hermite transform coefficients o...

Synchronizing a Database to Improve Freshness
In this paper we study how to refresh a local copy of an autonomous data source to maintain the copy up-to-date. As the size of the data grows, it becomes more difficult to mainta...

New efficient algorithms for computing effective capacitance
We describe a novel iterationless approach for computing the effective capacitance of an interconnect load at a driving gate output. Our new approach is considerably faster than p...
