The Web proxy cache placement problem is often formulated as a classical optimization problem: place N proxies within an internetwork so as to minimize the average user response t...
This paper investigates the situation where a group of terminals can be simultaneously connected to several base stations using distinct technologies on nonoverlapping frequency b...
This paper introduces a linear programming (LP) technique that performs ratedistortion based optimization for constrained video coding. Given the assumption of piecewise linear an...
We study fundamental aspects related to the efficient processing of the SPARQL query language for RDF, proposed by the W3C to encode machine-readable information in the Semantic W...
Two challenges in computer vision are to accommodate noisy data and missing data. Many problems in computer vision, such as segmentation, filtering, stereo, reconstruction, inpain...
