Les élèves en accompagnement scolaire : adéquation entre public visé et public accueilli

2002

This article examines the adjustment between pupils targeted to study in after school programs and pupils who are already in attendance. Several analyses have been drawn up on a large cross-section of seven and ten year-old pupils and have shown that most of them have social problems and/or are under-achieving. However, a third of the cross-section are not experiencing difficulties and therefore should not have been enrolled. Regarding the selection process of the after school programs, the analysis also shows that weak and foreign pupils more frequently seek school support after the normal school day.

How Do French Junior Secondary Schools Operate ? Academic Achievement, Grading and Streaming of Students

1989

International audience; This paper is concerned with the operation of Junior Secondary Schools in France. Students' school careers have been analysed in three sequential and cumulative components: student progress in learning in the junior secondary school, student grading by teachers, and student streaming, i.e., admission, or not, into a general form 3. For each of the three mechanisms described above, the authors examine whether they are influenced by the schooling context, which schooling context (school and/or classroom), and which characteristics of those contexts it is relevant to consider. Finally, they focus on the process by which the large social inequalities visible after the pu…

Classification of spectra and search for biomarkers in prostate tumours from proton nuclear magnetic resonance spectroscopy

2010

Prostate cancer is the most common cancer in men over 50 years. Current detection methods either lack sensitivity or specificity or are unpleasant for the patient. Magnetic resonance spectroscopy allows the study of metabolism in vivo. The use of a high field machine (≥3T) has allowed us to dispense with the use of an endorectal coil, which is particularly uncomfortable for the patient. The objective of this thesis is to create an automatic method to detect cancer by processing data obtained through magnetic resonance spectroscopy MRS is a complex phenomenon, very sensitive to acquisition conditions. Firstly, we have studied how to improve and optimise signal acquisition. However, even with…

Analyses spectrale et texturale de données haute résolution pour la détection automatique des maladies de la vigne

2019

‘Flavescence dorée’ is a contagious and incurable disease present on the vine leaves. The DAMAV project (Automatic detection of Vine Diseases) aims to develop a solution for automated detection of vine diseases using a micro-drone. The goal is to offer a turnkey solution for wine growers. This tool will allow the search for potential foci, and then more generally any type of detectable vine disease on the foliage. To enable this diagnosis, the foliage is proposed to be studied using a dedicated high-resolution multispectral camera.The objective of this PhD-thesis in the context of DAMAV is to participate in the design and implementation of a Multi-Spectral (MS) image acquisition system and …

Arrangements de cercles sur une sphère: Algorithmes et Applications aux modèles moléculaires representés par une union de boules

2008

Since the early work of Richard et al., geometric constructions havebeen paramount for the description of macromolecules and macro-molecularassemblies. In particular, Voronoï and related constructions have beenused to describe the packing properties of atoms, to compute molecularsurfaces, to find cavities. This thesis falls in this realm, andafter a brief introduction to protein structure, makes fourcontributions.First, using the sweep line paradigm of Bentley and Ottmann, wepresent the first effective algorithm able to construct the exactarrangement of circles on a sphere. Moreover, assuming the circlesstem from the intersection between spheres, we present a strategy to reportthe covering …
