Regularity of the inverse of a Sobolev homeomorphism in space
2006
Let Ω ⊂ Rn be open. Given a homeomorphism of finite distortion with |Df| in the Lorentz space Ln−1, 1 (Ω), we show that and f−1 has finite distortion. A class of counterexamples demonstrating sharpness of the results is constructed.
Comment évaluer et mesurer la conflictualité liée aux usages de l'espace ? Eléments de méthode et de repérage
2010
Cet article a pour objet de présenter le travail réalisé depuis quelques années par une équipe pluridisciplinaire sur la question des conflits d’usage de l’espace et de révéler la méthodologie d’enquête et de collecte de données, ainsi que la structure de la base de données qui en est issue. Dans un premier temps nous procédons à une définition du champ des investigations, en donnant une définition de ces conflits, de leurs caractéristiques, des mobiles et des manifestations de la conflictualité, ainsi que des acteurs impliqués (I). Nous exposons ensuite notre méthode de repérage des conflits, fondée sur un diagnostic de zone et la mise en commun de différentes méthodes de recueil de donnée…
Attention-Based Landmark Selection in Autonomous Robotics
2007
This paper describes a robotic architecture that uses visual attention mechanisms for autonomous navigation in unknown indoor environments. A foveation mechanism based on a bottom-up attention system allows the robot to autonomously select landmarks, defined as salient points in the camera images. Landmarks are memorized in a behavioral fashion by coupling sensing and acting to achieve a representation that is view and scale independent. Selected landmarks are stored in a topological map. During the navigation a top-down mechanism controls the attention system to achieve robot localization. Experiments and results show that our system is robust to noise and odometric errors, being at the sa…
Attention-based environment perception in autonomous robotics
2007
This paper describes a robotic architecture that uses visual attention mechanisms for autonomous navigation in unknown indoor environments. A foveation mechanism based on classical bottom-up gaze shifts allows the robot to autonomously select landmarks, defined as salient points in the camera images. Landmarks are memorized in a behavioral fashion, coupling sensing and acting to achieve a representation view and scale independent. Selected landmarks are stored in a topological map; during the navigation a top-down mechanism controls the attention system to achieve robot localization. Experiments and results show that our system is robust to noise and odometric errors, being at the same time…
MultiSlice human organ extraction based on GVF
2008
Segmentation techniques based on active contours algorithm are widely used in medical imaging. Unfortunately, they require a lot of parameters to be used and this can rep- resent an issue for those physicians with not much informatics skills. This paper proposes a software tool which allows to segment multiple slice can differ organ extraction setting a small number of parameters. Moreover, the tool offers the functionality to perform a multiple segmentation the same time, so that an entire volume composed by hundreds slices can be segmented.
Chapter 11: Affect and Mathematical Modeling Assessment: A Case Study on Engineering Students’ Experience of Challenge and Flow During a Compulsory M…
2019
This chapter describes a study on engineering students’ affect while working on the Tracker Project Task, a group assessment task that asks students (1) to use digital tools (the camera in their smart phones and free tracker software) to capture the movement of an object, (2) to mathematically model that movement, and (3) to create a poster reporting on the video analysis of the movement.

Advanced functionality for radio analysis in the Offline software framework of the Pierre Auger Observatory
2011
The advent of the Auger Engineering Radio Array (AERA) necessitates the development of a powerful framework for the analysis of radio measurements of cosmic ray air showers. As AERA performs ‘‘radio- hybrid’’ measurements of air shower radio emission in coincidence with the surface particle detectors and fluorescence telescopes of the Pierre Auger Observatory, the radio analysis functionality had to be incorporated in the existing hybrid analysis solutions for fluorescence and surface detector data. This goal has been achieved in a natural way by extending the existing Auger Offline software framework with radio functionality. In this article, we lay out the design, highlights and features …
From This Side of Pyrenees: An Overview of Autoethnography in Spain
2022
In recent years, we have witnessed a growing interest in autoethnography in Spain. However, the visibility of Spanish autoethnography within and beyond our borders continues to be limited. In this article, I have examined autoethnographic texts written by Spanish authors for the first time. I based this examination on a traditional bibliographic review of texts published in Spanish and English up to 2020. I organized texts according to my proposal for three stages of the development of Spanish autoethnography: its emergence, its dissemination from anthropology to other academic fields, and its consolidation and diversification. In these, I address the description of the content, the discipl…
