Let G = (V, E) be an undirected weighted graph with |V | = n and |E| = m. Let k 1 be an integer. We show that G = (V, E) can be preprocessed in O(kmn1/k ) expected time, construc...
The Image Distortion Model (IDM) has shown good retrieval quality in previous runs of the medical automatic annotation task of previous ImageCLEF workshops. However, one of its li...
Abstract. We introduce the notion of persistent authenticated dictionaries, that is, dictionaries where the user can make queries of the type “was element e in set S at time t?â€...

Internet-based virtual environments (VEs) let users explore multiple virtual worlds with many different geometric models which are downloaded rather than predistributed. To avoid ...
Abstract. We present algorithms for maintaining shortest path information in dynamic outerplanar digraphs with sublogarithmic query time. By choosing appropriate parameters we achi...
