This project, supported by the Swiss Federal Roads Authority (OFROU), focuses on the long term behaviour of road tunnels and on their main pathologies. As a tunnel is composed by lining structure and rock mass, it has been necessary to consider the effects ...
In this paper, we discuss meetings as an application domain for multimedia content analysis. Meeting databases are a rich data source suitable for a variety of audio, visual and multi-modal tasks, including speech recognition, people and action recognition ...
We present here a new way of indexing and retrieving data in huge datasets having a high dimensionality. The proposed method speeds up the selecting process by replacing scans of the whole data by scans of matching data. It makes use of two levels of catal ...
The work presented in this thesis deals with several problems met in information retrieval (IR), task which one can summarise as identifying, in a collection of "documents", a subset of documents carrying a sought information, i.e.. relevant for a request ...
In this paper we present the results of the StatSearch case study that aimed at providing enhanced access to statistical data available on the Web. In the scope of this case study we developed a prototype of an information access tool combining uerybased s ...
This document specifies a process for collecting a new corpus of meetings in the IDIAP Smart Meeting Room. This document is a working draft that is expected to be updated and augmented throughout the data collection process. This follows from an earlier da ...

Following the seminal work of Von Dreele, high quality powder X-ray diffraction studies on proteins are being established as a valuable complementary technique to single-crystal measurements. Several studies using a variety of experiments approaches have b ...
We describe a query-driven indexing framework for scalable text retrieval over structured P2P networks. To cope with the bandwidth consumption problem that has been identified as the major obstacle for full-text retrieval in P2P networks, we truncate posti ...
Switches and crossings (S&C) form an important asset of modern day railways. Current Decision Support Systems for track maintenance and renewal however do not provide help on maintenance and renewal management of S&C, due to the lack of understanding of th ...
