La fixité thématique du discours du vin en français et en allemand : analyses et proposition d’un modèle quadri-dimensionnel
2020
International audience; La présente contribution vise à souligner la fixité thématique dans les descriptions de vin en français et en allemand, réunies dans un corpus multimodal bilingue [3]. Il s'agira de mettre en évidence les quatre composantes sémantiques de ces descriptions [4], qui sont stabilisées pour les genres textuels associés à la vente du vin, mais qui subissent des variations en termes de proportions lorsque le genre textuel se spécifie. Ces continuités thématiques s'inscrivent en effet dans une progression textuelle marquée par d'incessants aller-retour avec la trame discursive de l'énoncé, et c'est précisément à l'interface texte-discours que s'actualisent (entre autres), da…
Poids culturel du discours numérique de la bière en allemand Pour une approche par la sémantique discursive
2019
International audience; La présente contribution vise à développer la méthodologie de la sémantique discursive en convoquant la sémantique des cadres pour l’analyse du discours sensoriel. Seront, dans un premier temps, discutés les deux notions de discours et de sensoriel pour partir d’une définition stabilisée et opérationnalisable. Les cadres sémantiques sont ensuite employés pour l’analyse d’un corpus numérique original en langue allemande de publications d’Instagram générées à partir de hashtags portant sur la bière. Il sera alors démontré en quoi la culture influence la construction du sens du texte de la publication.
Detección temprana de la dislexia mediante el reconocimiento de voces
2015
Un aspecto clave para la intervención educativa específica es la detección temprana de niños con riesgo de dislexia. En este trabajo presentamos una sencilla tarea conductual de asociación de voces (modalidad auditiva) con avatares (modalidad visual), en la que las personas con dislexia muestran un rendimiento más bajo que las personas normo-lectoras. Dicho patrón de datos ocurre no solamente con lectores adultos, sino también con niños. Por tanto, esta tarea de integración multisensorial puede ser empleada como un marcador de la dislexia, en conjunto con otras tareas (v.g., conocimiento fonológico).
Integration of large-area optical imagers for biometric recognition and touch in displays
2021
In recent years there has been an increasing interest to integrate optical sensing in mobile displays, for instance, for biometric fingerprint scanning functionality. There are several routes to incorporate optical fingerprint functionality within the full display area, each with their own benefits and challenges. Here we investigate the different integration routes using large-area, ultra-thin imagers based on organic photodiodes.
Decentralized Deployment of Mobile Sensors for Optimal Connected Sensing Coverage
2008
In this paper, we address the optimal connected sensing coverage problem, i.e., how mobile sensors with limited sensing capabilities can cooperatively adjust their locations so as to maximize the extension of the covered area while avoiding any internal “holes”, areas that are not covered by any sensor. Our solution consists in a distributed motion algorithm that is based on an original extension of the Voronoi tessellation.
Effects of Tray-Drying on the Physicochemical, Microbiological, Proximate, and Sensory Properties of White- and Red-Fleshed Loquat (Eriobotrya Japoni…
2022
Loquat fruits, highly valued by consumers for their characteristic aroma and pleasant taste, have a short post-harvest life and are susceptible to mechanical damage, loss of firmness, and initial organoleptic characteristics. The aim of this work was to develop a drying method suitable for storing loquat fruits in polyamide/polyethylene (PA/PE) bags containing two gaseous mixtures (treatments): MAPN2 (100% N2) and MAPP (21% O2 and 0.04% CO2), at room temperature (20 ± 1 °C) for at least 2 months. The effects of these conditions on the physico-chemical, microbiological, proximate, and sensory properties of fruit stored over a 50-day time interval were studied. The results showed that convect…
The dynamics of aroma release during consumption of candies of different structures, and relationship with temporal perception
2011
; We investigated the role of both candy texture and eating technique (melting or chewing) on the dynamics of aroma release. One novelty of this type of analysis was the simultaneous application of instrumental and sensory analysis. Four candy textures were established based on their storage modulus at 1 Hz by varying the gelatine content between 0 and 15% w/w. The in vivo release of three aroma compounds was monitored using Proton Transfer Reaction Mass Spectrometry and with a trained panel of testers. The gelatine content had no significant effect on the headspace/product partition and diffusion properties of the aroma compounds. The highest in vivo release for all aroma compounds was ob…
3-4 gadus vecu bērnu sensorās prasmju pilnveides iespējas brīvdabas pedagoģijā

Reti sismiche urbane per monitoraggio sismico monitoraggio strutturale ed allerta precoce
2021
In questa tesi, viene effettuato un analisi preliminare in cui si mette in evidenza come l'italia sia un paese a rischio sismico, poichè possiede molti centri storici con strutture non progettate per eventi sismici di media entità. Si è prestato molta attenzione su quante vite umane vengono salvate dopo un terremoto catastrofico. L'analisi fa emergere come, è importante essere tempestivi nell'estrarre le persone rimaste sotto le macerie, poichè la percentuale di persone estratte vive si mantiene alta solo entro le 48 ore dall'evento. Dopo 96 ore questa percentule si attesta a 0. In eventi passati spesso i soccorsi sono arrivati con giorni di ritardo nelle zone più devastate. L'obbiettivo ch…
Pleasure of eating: a lever for the adoption of healthy eating in children
2018
Childhood obesity, despite a recent stabilization, is still a matter of concerns in the European region and elsewhere (WHO, 2017), i.e. in France (where it concerned 17% of 3-14 y-old children in 2015; INCA3). Since many years, public health campaigns have encouraged healthy eating in many countries over the world, in particular by highlighting the beneficial effect on health of some food groups (e.g., in France “For your health, eat five fruits and vegetables a day”). However, the WHO noted in 2017 that among adolescents, “daily consumption of fruit and vegetables increased slightly between 2002 and 2014, but overall prevalence remains low ; and daily consumption of sugary soft drinks and …
