Scientific experiments produce large volumes of data represented as complex objects that describe independent events such as particle collisions. Scientific analyses can be express...
The HiPAC project is investigating active, time-constrained databasemanagment. An active DBMS is one which automatically executes specified actions when speciifed conditions arise...
Abstract. Bottom-up approaches, which rely mainly on continuity principles, are often insufficient to form accurate segments in natural images. In order to improve performance, rec...
