Using a Semantic Wiki for Documentation Management in Very Small Projects

International audienceThe emerging ISO/IEC 29110 standard Lifecycle profiles for Very Small Entities is targeted at very small entity (VSE) having up to 25 people, to assist them unlock the potential benefits of using software engineering standards. VSEs may use semantic web technologies to improve documentation management infrastructure and processes. We proposed to use a semantic wiki for documentation management based on an identification scheme inspired from an IFLA proposition called Functional Requirements for Bibliographic Records. The document identification scheme allows documents to be managed by the internal resource management of the semantic wiki, hence benefiting from a straightforward but powerful version control. With few inputs of semantic annotations by VSE employees - through usable semantic forms and templates, the semantic wiki acts as a library catalog, and users can find, identify, select, obtain, and navigate resources

Inner Garden, interface tangible pour une approche sensorielle et poétique du biofeedback

DemoInner Garden is a multisensory stimulation device. It appears as a sandbox that the user is invited to manipulate in order to shape a landscape. A depth camera is used to compute a colormap that is projected in real time. Another layer of interaction takes place through the measurment of user’s inner states. For example, the breathing can directly influence waves’ pace. This device aims to increase engagement during a therapeutic activity or during a rehabilitation exercice.Inner Garden est un dispositif de stimulation multisensorielle. Il se présente sous la forme d’un bac à sable que l’utilisateur.rice est invité.e à manipuler pour modeler un paysage. Une caméra de profondeur permet de calculer une carte de couleurs projetée en temps réel. Un niveau d’interaction supplémentaire est achevé via la mesure d’état internes. Par exemple la respiration peut directe- ment influer le rythme des vagues. Ce dispositif vise à augmenter l’engagement lors d’un atelier thérapeutique ou d’une activité de rééducation

Relation between air pollution and allergic rhinitis in Taiwanese schoolchildren

BACKGROUND: Recent findings suggest that exposure to outdoor air pollutants may increase the risk of allergic rhinitis. The results of these studies are inconsistent, but warrant further attention. The objective of the study was to assess the effect of relation between exposure to urban air pollution and the prevalence allergic rhinitis among school children. METHODS: We conducted a nationwide cross-sectional study of 32,143 Taiwanese school children. We obtained routine air-pollution monitoring data for sulphur dioxide (SO(2)), nitrogen oxides (NOx), ozone (O(3)), carbon monoxide (CO), and particles with an aerodynamic diameter of 10 μm or less (PM(10)). A parent-administered questionnaire provided information on individual characteristics and indoor environments (response rate 92%). Municipal-level exposure was calculated using the mean of the 2000 monthly averages. The effect estimates were presented as odds ratios (ORs) per 10 ppb change for SO(2), NOx, and O(3), 100 ppb change for CO, and 10 μg/m(3 )change for PM(10). RESULTS: In two-stage hierarchical model adjusting for confounding, the prevalence of allergic rhinitis was significantly associated with SO(2 )(adjusted odds ratio (OR) = 1.43, 95% confidence interval (CI): 1.25, 1.64), CO (aOR = 1.05, 95% CI: 1.04, 1.07), and NOx (aOR = 1.11, 95% CI: 1.08, 1.15). Contrary to our hypothesis, the prevalence of allergic rhinitis was weakly or not related to O(3 )(aOR = 1.05, 95% CI: 0.98, 1.12) and PM(10 )(aOR = 1.00, 95% CI: 0.99, 1.02). CONCLUSION: Persistent exposure to NOx, CO, and SO(2 )may increase the prevalence of allergic rhinitis in children

Detection of Greenhouse Gas Precursors from Diesel Engines Using Electrochemical and Photoacoustic Sensors

Atmospheric pollution is one of the worst threats to modern society. The consequences derived from different forms of atmospheric pollution vary from the local to the global scale, with deep impacts on climate, environment and human health. Several gaseous pollutants, even when present in trace concentrations, play a fundamental role in important processes that occur in atmosphere. Phenomena such as global warming, photochemical smog formation, acid rain and the depletion of the stratospheric ozone layer are strongly related to the increased concentration of certain gaseous species in the atmosphere. The transport sector significantly produces atmospheric pollution, mainly when diesel oil is used as fuel. Therefore, new methodologies based on selective and sensitive gas detection schemes must be developed in order to detect and monitor pollutant gases from this source. In this work, CO2 Laser Photoacoustic Spectroscopy was used to evaluate ethylene emissions and electrochemical analyzers were used to evaluate the emissions of CO, NOx and SO2 from the exhaust of diesel powered vehicles (rural diesel with 5% of biodiesel, in this paper called only diesel) at different engine rotation speeds. Concentrations in the range 6 to 45 ppmV for ethylene, 109 to 1,231 ppmV for carbon monoxide, 75 to 868 ppmV for nitrogen oxides and 3 to 354 ppmV for sulfur dioxide were obtained. The results indicate that the detection techniques used were sufficiently selective and sensitive to detect the gaseous species mentioned above in the ppmV range

Modèles et langage pour la conception et la manipulation de composants réutilisables de domaine

Le domaine de la conception des systèmes d'information est un secteur très demandeur en techniques et méthodes nouvelles visant à améliorer la qualité des produits et la performance des processus de conception. Ces besoins ont tait émerger des méthodes et outils innovants, aujourd'hui largement adoptés et utilisés. II est maintenant possible d'envisager une approche de développement basée sur la réutilisation de composants existants et éprouvés. Une telle approche doit permettre de réduire le temps de conception des systèmes d information, d'en améliorer la qualité et d'en faciliter la maintenance... Cinq résultats essentiels ont été produits à l'issue de ce travail de recherche. Une démarche de conception de systèmes de réutilisation permet d'identifier les connaissances de domaine à réutiliser, de les abstraire afin de taire apparaître la variabilité du domaine et de les discriminer. Cette démarche s'appuie sur un méta-modèle de domaine. Celui-ci offre un ensemble de concepts pour spécifier les buts, activités et objets d'un domaine. II peut être utilisé aussi bien lors de la modélisation de champs d'application que de méthodes d'ingénierie des systèmes d' information. Un modèle de composants réutilisables de domaine permet d'opérationnaliser, en vue de leur réutilisation, les connaissances ainsi formalisées en les structurant sous forme de composants de domaine. Des opérateurs et un processus de manipulation de composants sont décrits. Ils visent à supporter et guider l'ingénierie par réutilisation. Enfin, une plate-forme logicielle pour la conception et la manipulation de composants de domaine a été spécifiée et développée pour supporter l'ensemble de la démarche.AIX-MARSEILLE3-BU Sc.St Jérô (130552102) / SudocSudocFranceF

Exploring Biofeedback with a Tangible Interface Designed for Relaxation

International audienceAnxiety is a common health issue that can occur throughout one's existence. In this pilot study we explore an alternative technique to regulate it: biofeedback. The long-term objective is to offer an ecological device that could help people cope with anxiety, by exposing their inner state in a comprehensive manner. We propose a first iteration of this device, "Inner Flower" , that uses heart rate to adapt a breathing guide to the user; and we investigate its efficiency and usability. Traditionally, such device requires user's full attention. We propose an ambient modality during which the device operates in the peripheral vision. Beside comparing "Ambient" and "Focus" conditions, we also compare the biofeedback with a sham feedback (fixed breathing guide). We found that the Focus group demonstrated higher relaxation and performance on a cognitive task (N-back). However, there was no noticeable effect of the Ambient feedback, and the biofeedback condition did not yield any significant difference when compared to the sham feedback. These results, while promising, highlight the pitfalls of any research related to biofeedback, where it is difficult to fully comprehend the underlying mechanisms of such technique

Grasping objects with a cable-driven parallel robot designed for transfer operation by visual servoing

International audienceOur objective is to extend the assistance function- alities of the cable-driven parallel robot Marionet-Assist, designed principally for transfer operation, by allowing it to grasp usual objects (knives, box of medicines, phone, ***) by using visual servoing. Our crane robot has a configuration that provides three translational d.o.f., and a camera was added to its end-effector. In order to compute the translational velocity sent to the robot controller, the area and center of gravity in the image of the object to be grasped are used. Experimental results are presented. They show the robustness of our scheme with respect to modeling errors and an excellent positioning accuracy allowing grasping
