Our aim was to perform a dynamic study of contrast enhancement of the intestinal wall in patients with Crohn’s disease to quantitatively assess local inflammatory activity. We studied a population of 50 patients with histologically proven Crohn’s disease. Magnetic resonance imaging (MRI) was performed using a 1.5-T magnet with a phased-array coil and(More)
Heuristic search using heuristics extracted from the delete relaxation is one of the most effective methods in planning. Since finding the optimal solution of the delete relaxation is intractable, various heuristics introduce independence assumptions, the implications of which are not yet fully understood. Here we use concepts from graph theory to show that(More)
Time granularity constraint reasoning is likely to have a relevant role in emerging applications like GIS, time management in the Web and Personal Information Management applications for mobile systems. This paper reports recent advances in the development of a system for solving temporal constraint satisfaction problems where distance constraints are(More)
