Architecture domestique punique, hellénistique et romaine. Sauvegarde et mise en valeur / Architettura domestica punica, ellenistica e romana. Salvag…
2014
Finanziato dall’Unione Europea nell’ambito della cooperazione transfrontaliera Italie Tunisie 2007-2013, il Progetto APER (Architettura domestica punica, ellenistica e romana: salvaguardia e valorizzazione) ha unito istituzioni italiane e tunisine (il capofila Polo Didattico di Agrigento dell’Università di Palermo, con i partner Consorzio Universitario Provincia di Agrigento, Institut National du Patrimoine e Agence de Mise en Valeur du Patrimoine et de Promotion Culturelle e gli enti associati Parco della Valle dei Templi di Agrigento, Provincia Regionale di Agrigento, Centro Regionale per la Progettazione e il Restauro della Regione Siciliana, École Nationale d’Architecture et Urbanisme d…
Améliorer l'école
2006
06003; "L'idée que l'école peut s'améliorer n'est pas qu'un acte de foi. Les recherches empiriques en sciences sociales mettent en évidence que l'école agit à partir d'un contexte social qui en détermine fortement les effets mais que, dans un contexte semblable, certaines approches pédagogiques, certains établissements, certains systèmes éducatifs produisent des effets différents : des élèves faibles moins faibles, des inégalités sociales moins élevées. La recherche en sciences sociales peut contribuer à cette amélioration de plusieurs façons, à la condition de se rappeler que la transformation radicale de l'école n'est pas possible, que les obstacles rencontrés par les élèves ne sont pas d…
Dynamiques de classe et efficacité scolaire
2003
The present research aims at describing the efficiency of teaching practices involved in dynamic "teaching-training" processes. Our main approach consisted in relating in-class-monitoring to the results of knowledge-acquisition by pupils so as to better explain through what means the pupils’ knowledge and competence are acquired. At a theoretical level this implies combining the "process-product" paradigm along with the "ecological" paradigm [ 1]. Results obtained indicate that bringing together the analysis of teaching practices with the evaluation of their impact "which are still limited to an exploratory stage" are a method well-worth pursuing. [ 1] See above the general introduction to …
Idéologie et production de connaissances : le poids de l'inspection
2013
Il s'agit d'identifier dans quelle mesure l'inspection, en EPS, est productrice de connaissances (notamment dans les revues professionnelles) et/ou d'idéologie(s), de la fin des années 1950 au début des années 1990. Nous montrons que si une déontologie de neutralité est largement partagée, les postures et actions de l'inspection permettent de dégager des sensibilités différentes (notamment en terme de rapport aux pratiques sportives extra-scolaires et à leur "démocratisation").

Contribution à la caractérisation de la mémoire des aliments
2008
Memory plays a fundamental role in the acquisition of food likes and dislikes. As a consequence, a better understanding food memory will contribute to a better understanding food choice and behavior. This work sets out several experiments based on a common recognition paradigm: during a first session, participants are exposed to the food to be remembered (target) under conditions ensuring incidental learning. After a certain retention interval, participants are asked to recognize the target among a set of distractors with a flavor and/or a texture slightly different from the target. In line with previous works on food memory, three main results emerged from this work. First, participants of…
3D shape recognition and matching for intelligent computer vision systems
2018
This thesis concerns recognition and matching of 3D shapes for intelligent computer vision systems. It describes two main contributions to this domain. The first contribution is an implementation of a new shape descriptor built on the basis of the spectral geometry of the Laplace-Beltrami operator; we propose an Advanced Global Point Signature (AGPS). This descriptor exploits the intrinsic structure of the object and organizes its information in an efficient way. In addition, AGPS is extremely compact since only a few eigenpairs were necessary to obtain an accurate shape description. The second contribution is an improvement of the wave kernel signature; we propose an optimized wave kernel …
Automatic recognition of tree species from 3D point clouds of forest plots
2014
The objective of the thesis is the automatic recognition of tree species from Terrestrial LiDAR data. This information is essential for forest inventory. As an answer, we propose different recognition methods based on the 3D geometric texture of the bark.These methods use the following processing steps: a preprocessing step, a segmentation step, a feature extraction step and a final classification step. They are based on the 3D data or on depth images built from 3D point clouds of tree trunks using a reference surface.We have investigated and tested several segmentation approaches on depth images representing the geometric texture of the bark. These approaches have the disadvantages of over…
Image-based detection and classification of allergenic pollen
2015
The correct classification of airborne pollen is relevant for medical treatment of allergies, and the regular manual process is costly and time consuming. An automatic processing would increase considerably the potential of pollen counting. Modern computer vision techniques enable the detection of discriminant pollen characteristics. In this thesis, a set of relevant image-based features for the recognition of top allergenic pollen taxa is proposed and analyzed. The foundation of our proposal is the evaluation of groups of features that can properly describe pollen in terms of shape, texture, size and apertures. The features are extracted on typical brightfield microscope images that enable…
Spectral interest points and texture extraction and fusion for identification, control and security
2018
Biometrics is an emerging technology that proposes new methods of control, identification and security. Biometric systems are often subject to risks. Face recognition is popular and several existing approaches use images in the visible spectrum. These traditional systems operating in the visible spectrum suffer from several limitations due to changes in lighting, poses and facial expressions. The methodology presented in this thesis is based on multispectral facial recognition using infrared and visible imaging, to improve the performance of facial recognition and to overcome the deficiencies of the visible spectrum. The multispectral images used in this study are obtained by fusion of visi…
