Multiple Range Query Optimization in Spatial Databases
In order to answer efficiently range queries in 2-d R-trees, first we sort queries by means of a space filling curve, then we group them together, and finally pass them for process...

A Hierarchical Model of Shape and Appearance for Human Action Classification
We present a novel model for human action categorization. A video sequence is represented as a collection of spatial and spatial-temporal features by extracting static and dynamic...

Improved dynamic programs for some batching problems involving the maximum lateness criterion
We study four scheduling problems involving the maximum lateness criterion and an element of batching. For all the problems that we examine, algorithms appear in the literature th...
