In this paper, we introduce a novel metadata model for describing scalable and interactive TV services that can be enriched with supplemental multimedia information. The model all...
This paper addresses a novel linear programming based approach to optimize the choice of the encoding parameters for the MPEG-4 AAC audio codec. Current techniques solve the encod...
We study simple greedy approximation algorithms for general class of integer packing problems. We provide a novel analysis based on the duality theory of linear programming. This e...
We study the complexity of the reachability problem for a new subclass of Petri nets called simple-circuit Petri nets, which properly contains several well known subclasses such as...
In this paper, the stability of objects in graspless manipulation (or nonprehensile manipulation) is investigated. In contrast with the stability of grasps, it is crucial for the ...
