In this paper, we describe our first participation in the ImageCLEF campaign. The SINAI research group participated in both the ad hoc task and the medical task. For the first task, we have used several translation schemas as well as experiments with and without pseudo relevance feedback (PRF). For the medical task, we have also submitted runs with and without PRF, and experiments using only te...

This paper describes the first participation of the SINAI group of the University of Jaén in TRECVID 2007. We have only participated in the automatic search task. Our approach is a very simple system made up of three main modules: the text-based retrieval subsystem, the image-based retrieval subsystem and the fusion module. We have submitted several runs exploring fusion of both textual and vis...

Egypt is highly exposed to flash flood hazards, particularly in Sinai Peninsula and along the Red Sea coast, causing sudden huge damages constructions losses human lives during a very short time. This paper investigates dominant characterization of morphometrical features their relationships with hydrological behaviors an important strip western coast. The study focuses on analyzing October 200...

412 NOTICES OF THE AMS VOLUME 51, NUMBER 4 Billiards are dynamical systems. In the simplest case, a “billiard table” is a compact domain Q ⊂ Rd with a piecewise smooth boundary. For a large part of the theory the class of smoothness plays no role. The reader is invited to think about components of the boundary ∂Q as subsets of C∞-submanifolds of codimension 1. The phase space M of the billiard ...

This paper describes the SINAI team participation in the ImageCLEF campaign. The SINAI research group has participated in both the ad hoc task and the medical task. The experiments accomplished in both cases result from very different approaches. For the ad hoc task the main Information Retrieval (IR) system used combines the document lists retrieved by two IR systems, and uses online translato...

This paper describes the first participation of the SINAI research group in the VideoCLEF 2008 track. We have only submitted runs for the classification task on Dutch and English languages. Our approach has consisted in the use of a particular Information Retrieval system as classification architecture, using the speech transcriptions as textual queries and generating textual corpus for each to...
