Preface

The Colloquium Colibri was born from the will of French and Brazilian researchers to meet at the occasion of the "Ano da França no Brasil 2009", in order to exchange experiences on the most current topics in Technologies of Information. It was also an opportunity to commemorate 35 years of continuous scientific relations.

This colloquium would not have been possible without a strong commitment from the INRIA, the SBC, and the INF/UFRGS. From the INRIA side, the Direction de Partenariats Européens (DPE - Direction of European Partnerships) wished to associate the scientific partners of both sides in European projects. The Direction de Relations Internationales (DRI - Direction of International Relationships) aimed at the opportunity to have a balance of the current and future collaborations, as well as to meet its institutional partners - especially those with whom calls for projects are issued.

The perspective of meeting students and scientists, actively engaged in their domains, at the yearly SBC conference, which is the very place where they regularly gather, has suggested to associate Colibri to the CSBC'09. The SBC has immediately agreed on this project and has supported it all along its preparation. Finally, nothing could have been possible without the enthusiasm of the organizers from the INF/UFRGS, who have succeeded in overcoming one by one, and with strong determination, all the obstacles.

Thus, Colibri has been set up as a two days colloquium, with an accumulation of events devised to foster the meetings among the participants.

The organization and the preparation have been led by a bilateral Steering Committee, gathering the partners from the INRIA, the SBC and the INF/UFRGS. The scientific program has been elaborated by a Program Committee constituted of renown researchers from both countries, under the co-presidency of Nelson Maculan and Malik Ghallab.

The call for participation has been especially well received, since 44 articles have been submitted to Colibri. There were 94 Brazilian authors, and 35 French, belonging respectively to 30 institutions in Brazil (from 13 States), and 23 in France. The INRIA is but one of these since many French authors belong to mixed project-teams. This slight unbalance may result from the special attention that France has had this year in Brazil. It is also due to 17 articles which have been submitted unilaterally from Brazilian teams, vs. 3 unilateral French papers. On the whole, most of the articles have been co-signed by Brazilian and French researchers, and highlight works of common interest.

The topics that have been treated are, in decreasing order: Multimedia Data Treatment and Virtual Reality (11), Software Engineering and Algorithms (7), Biocomputing and Applications to Health (7), Network and Nomadism (6), Automatics and Numerical Analysis (5), Impacts and Perspectives~(4).

Two speakers of each country have accepted to present their most recent works, as well as grand challenges in many fields of IT, in particular in "Networks and Nomadism", and "High Performance Computing".

We would like to thank here all the members of the different committees (Program, Steering and Organization) who have contributed to the success of this manifestation, sometimes giving much of their valuable time. We also thank all the speakers and participants for their involvement. We particularly appreciate the financial sponsoring of the French Embassy, the CAPES, Bull and Microsoft. Finally, we would like to acknowledge the representation of many State and Federal Agencies, which have agreed to come and share their experience on the topics dealing with international cooperation.

We hope that these proceedings will contribute to shed a light on the most active research areas between our two countries, and to give us all the motivation to keep on progressing together.
