Comparative study of the effectiveness of educational policies of inclusion in France and sub-Saharan Africa: a literature review
2013
Recommended by international bodies (UNESCO, 2006; 2008), inclusive education is based on the principle of equal opportunity. It aims to promote inclusion in the broad sense of the term by addressing specific audiences excluded or marginalized from educational systems. In recent years, regulatory frameworks have been defined for the education of certain categories excluded from educational systems including children with disabilities. Educational policies concerned with taking into account the needs of this group are also implemented. Do these policies promote effective integration of students with disabilities? To what extent can these policies be considered as effective? This paper presen…
Two photogrammetric methods for measuring flat elements in buildings under construction
2008
Usually, determining the dimensions of flat surfaces in buildings under construction, such as window cavities and facade coating materials, are done by direct measuring methods using tapes and plummets. Sometimes these methods suppose a slow and highly risky work for operators. This research proposes the substitution of these procedures by indirect methods based on close range photogrammetry and laser distance measurement. First, we show the design, construction and calibration of a system composed by a digital camera and a lasermeter mounted on a support with multiple turning positions. Next, two different facade element measuring methodologies are shown. The first method is based on takin…
Smart cameras on a chip: using complementary metal-oxide-semiconductor (CMOS) image sensors to create smart vision chips
2020
Abstract: In this chapter, we introduce the fundamental concept of smart cameras on a chip or smart vision chips that simultaneously integrate the same die image capture capability and highly complex image processing. Successive technology scaling has made possible the integration of specific processing elements designed at chip level, at column level or at pixel level. To illustrate this continuous evolution, we survey three different categories of vision chips, exploring first the pioneering works on artificial retinas, then describing the most significant computational chips, and finally presenting the most recent image processing chips able to perform complex algorithms at a high frame …
First results of iButton® loggers and infrared camera application inside a greenhouse
2017
Greenhouse microclimate management (temperature, relative humidity) plays a very important role in order to optimize the production process improving pest and disease control, irrigation and energy efficiency. The systems mostly used in Sicily (south Italy) to record the ambient parameters are made up of fixed measuring stations able to give useful information about the climate inside the greenhouse limited to some pre-fixed points. In this study we texted a novel system made up of humidity and temperature data loggers (iButton®) placed inside a greenhouse. The iButton® temperature/humidity logger (DS1923) is a rugged, self-sufficient system that measures temperature and/or humidity and r…
Multimodal user interface for a semi-robotic visual assistance system for image guided neurosurgery
2005
Abstract We developed a visual assistance system for image guided neurosurgery, consisting of a stereoscopic digital camera (exoscope) mounted on a semi-robotic manipulator. In order to minimize the operation time, the application-specific multimodal user interface enables hands-free manipulation of the exoscope. The surgeon wears thereby a head-mounted unit with a binocular display, a head tracker, a microphone and earphones. Different modes of view positioning and adjustment can be selected by voice and controlled by head rotation while pressing a miniature confirmation button mounted on a finger ring or suction device. Apart from the development of the mechatronic and software modules of…
Effect of Motion Artifact on Digital Camera Based Heart Rate Measurement
2017
International audience; Depression is one of the most prevalent mental disorders, burdening many people world-wide. A system with the potential of serving as a decision support system is proposed, based on novel features extracted from facial expression geometry and speech, by interpreting non-verbal manifestations of depression. The proposed system has been tested both in gender independent and gender based modes, and with different fusion methods. The algorithms were evaluated for several combinations of parameters and classification schemes, on the dataset provided by the Audio/Visual Emotion Challenge of 2013 and 2014. The proposed framework achieved a precision of 94.8% for detecting p…
An automatic quality system for injection molding
2007
This paper describes a fully automatic quality system for injection molding. The proposed system includes an on-line measurement platform with a digital camera, a methodology for adaptive design of experiments (DOE), statistical modeling, process monitoring, and a closed loop process control. The system has been tested in the manufacturing of plastic parts for mobile phones.
Enseignement technique et professionnel au Cameroun
2012
Le Cameroun, en tirant les leçons de la crise des années 90, a développé l'enseignement technique et la formation professionnelle ETFP. Comment est organisé ce sous-secteur ? Quelle articulation avec l'enseignement général et le marché de l'emploi ? Après une présentation globale du système éducatif, cet ouvrage décrit le sous-secteur de l'ETFP au Cameroun et la manière dont est organisée la formation des formateurs.
L'enseignement technique et professionnel au Cameroun : quelle place dans l'organisation du système éducatif ?
2014
International audience; Parti des missions assignées à une direction du ministère de l'Éducation Nationale, le cadre règlementaire de l'enseignement technique et professionnel au Cameroun a évolué au cours du temps, débouchant sur la création des ministères ayant en charge et de manière spécifique les questions d'Enseignement Technique et Professionnel ; fruit de l'expression d'une certaine volonté politique et de l'engagement des différents partenaires dans l'élaboration de la politique de l'ETFP et de son financement (Ngo Mélha, 2012). Cependant, de nombreux défis persistent pour la mise en place d'un véritable système d'ETFP. Sur la base d'une recherche documentaire, cet article propose …
Il viaggio di Ernest Duvergier de Hauranne nell'America di Lincoln. Riflessioni sui vizi e le virtù della democrazia.
2020
Nel giugno del 1864 il giovane liberale francese Ernest Duvergier de Hauranne (1843-1877), cresciuto in una famiglia rispettosa delle tradizioni parlamentari della monarchia orleanista, inizia il suo viaggio verso gli Stati Uniti. In otto mesi di viaggio – con la guerra civile ancora in corso e le elezioni presidenziali che avrebbero riconfermato Lincoln alla presidenza – percorrerà gli Stati Uniti e il Canada proseguendo verso Cuba e le Antille. Quell’itinerario americano, che gli procurerà una lesione polmonare che sarà la causa della prematura morte avvenuta a soli trentaquattro anni, resterà documentato nelle lettere e note, pubblicate in dodici articoli nella «Revue des Deux Mondes» e …
