Although at first sight, the web track might seem a copy of the ad hoc track, we discovered that some small adjustments had to be made to our systems to run the web evaluation. As we expected, the basic language model based IR model worked effectively on this data. Blind feedback methods however, seem less effective on web data. We also experimented with rescoring the documents based on several...

Hierarchical topic detection is a new task in the TDT 2004 evaluation program, which aims to organize a collection of unstructured news data in a directed acyclic graph (DAG) structure, reflecting the topics discussed in the collection, ranging from rather coarse category like nodes to fine singular events. The HTD task poses interesting challenges since its evaluation metric is composed of a t...

In this paper we present the results obtained with a new program dedicated to the automatic detection of trans-Neptunian objects (TNOs) with standard sets of images obtained in a same field of view. This program is available freely from the World Wide Web server of the Observatory of Besançon (http://www.obs-besancon.fr/www/ publi/philippe/tno.html) and is designed to be used with the Munich Im...

This paper summarizes the different algorithms developed in ATVS-UPM in order to submit a reliable Likelihood Ratio based forensic system, fully compliant with the bayesian framework for the analysis of forensic evidences, to 2003 NFI-TNO Forensic Speaker Recognition Evaluation. Once identified the main causes and consequences of the erratic estimation of Likelihood Ratios due to forensic condi...

Laguna Beach is a legacy stand-alone flight simulator, developed for demonstration purposes by Silicon Graphics, Inc. The Simulation group at TNO–FEL was able to successfully, and with only a modest amount of effort, convert this legacy application into an interoperable, HLA-compliant multi-aircraft federation. This rapid migration was achieved by using the RCI (Runtime Communication Infrastruc...

In 1992, Jewitt and Luu (1993) carried out a survey of 0.7 square degrees of the sky to a limiting magnitude of We present B–V and V–R colors for trans-neptunian objects (TNOs) 1994 TB and 1993 SC. We have found that these TNOs R p 25 and discovered the first TNO (1992 QB1). Thirtyhave colors almost as red as 5145 Pholus which are therefore six TNOs have been discovered as of June, 1996. The co...

BACKGROUND Improved survival in children with critical illnesses has led to new disease patterns. As a consequence evaluation of the well being of survivors of Pediatric Intensive Care Units (PICU) has become important. Outcome assessment should therefore consist of evaluation of morbidity, functional health and Health Related Quality of Life (HRQoL). Awareness of HRQoL consequences and physica...

One application of virtual environments is to form an affective appraisal of an environment, such as a building before it is constructed. But the affective appraisal attributed to a real environment can differ from the affective appraisal of the simulated virtual environment. One virtual environment specific problem is that people can experience cybersickness by watching virtual scene movement....

يعتبر الجريان السطحي نتيجة تساقط الأمطار من المكونات الهيدرولوجية الهامة في تقييم الموارد المائية. تتوفر العديد الطرق لتقدير ومع ذلك تظل طريقة حفظ وصيانة الترب الأمريكية SCS-CN الأكثر شيوعًا والأكثر استخدامًا حيث أن رقم منحنى (CN) هو عامل حاسم هذه الطريقة ويعتمد على استخدام الأرض أو غطاء (LU/LC) ونوع التربة وحالات رطوبة (AMC) تقدير السطحي. تم تطبيق هذا النهج بالتكامل مع نظم المعلومات الجغرافية (G...
