Evaluation de l’effet de recommandations sur l’introduction de textures dans les premiers mois de diversification alimentaire sur les pratiques paren…

National audience; Introduction et but de l’étude : Proposer des aliments texturés aux nourrissons rapidement après l’initiation de la diversification alimentaire est essentiel pour leur apprendre à bien mastiquer et développer un répertoire alimentaire sain. Le comité d’experts en nutrition de l’ESPGHAN recommande d’introduire les aliments texturés entre 8 et 10 mois au plus tard. Or, des travaux ont montré qu’en France, les purées restent privilégiées par de nombreux parents pendant la première année et que les enfants sont capables de manger des textures plus complexes d’après une étude comportementale. La question de la texture n’étant pas abordée en détail dans les recommandations de s…

Exploring the deviations from scale-invariance of spatial distributions of buildings using a Geographically Weighted Fractal Analysis. An application…

2018

In the early twentieth century a handful of French geographers and historians famously suggested that mainland France comprised two agrarian systems: enclosed field systems with scattered settlements in the central and western France, and openfield systems with grouped settlements in eastern France. This division between grouped and scattered settlements can still be found on the outskirts of urban areas. The objective of this paper is to determine whether the shape of urban areas varies with the type of built patterns in their periphery. To this end, we identify and characterise the local and global deviations from scale-invariance of built patterns in metropolitan France. We propose a new…

Multi-Scale Feature Extraction for Vehicle Detection Using Phis-Lbp

2018

International audience; Multi-resolutionobjectdetectionfacesseveraldrawbacksincludingitshighdimensionalityproducedby a richer image representation in different channels or scales. In this paper, we propose a robust and lightweight multi-resolution method for vehicle detection using local binary patterns (LBP) as channel feature. Algorithm acceleration is done using LBP histograms instead of multi-scale feature maps and by extrapolating nearby scales to avoid computing each scale. We produce a feature descriptor capable of reaching a similar precision to other computationally more complex algorithms but reducing its size from 10 to 800 times. Finally, experiments show that our method can obt…

Abnormal textures identification based on digital Hilbert optics methods: fundamental transforms and models

2018

The article presents the abnormal textures identification technology based on structural and statistical models of amplitude-phase images (APIm)– multidimensional data arrays (semantic models) and statistical correlation analysis methods using the generalized discrete Hilbert transforms (DHT)– 2D Hilbert (Foucault) isotropic (HTI), anisotropic (HTA) and total transforms – AP-analysis (APA) to calculate the APIm. The identified fragments of textures are obtained as examples of experimental observation of real mammograms contains areas of pathological tissues. The DHT based information technology as conceptual chart description is discussed and illustrated with DHO domain images. As additiona…

Définir, dénommer et traduire l'onctuosité : regards croisés sur une propriété gustative et ses dénominations en français, anglais et allemand

2006

International audience; Un simple coup d'œil sur les rayons crèmerie d'un supermarché ou sur les prospectus publicitaires suffit à s'en convaincre : onctueux est un attribut fort prisé en marketing alimentaire. Un test rapide sur google le confirme par ailleurs : pour les seules structures N + A, le moteur de recherche fournit une multitude d'occurrences pour ce domaine avec des syntagmes comme fromage blanc onctueux, potage onctueux mais aussi bûche de Noël au cœur onctueux, riz onctueux ou encore beurre de pomme onctueux. L'objectif de cette contribution est ainsi d'interroger les multiples emplois de l'adjectif onctueux en français et d'en envisager les équivalents possibles en anglais e…

The impact of high-temperature, short-time thermal treatment on texture and weight loss of green asparagus

1997

The kinetics of the degradation of texture and loss of weight of green asparagus heated to between 100 and 130 °C was studied. The texture of the asparagus was evaluated with two types of cells fitted to a universal texturometer: one cell measured resistance to cutting with a wire and the other was a Kramer cell. The two methods enabled distinction between the different thermal treatments, although the Kramer cell gave information about the behaviour of parts of the spear further away from the tip. The thermally induced degradation of the texture and loss of weight followed first-order kinetics. With respect to the texture, the parameters obtained with the wire cell 2.5, 5 and 7.5 cm from t…

Thermal Degradation of Green Asparagus Texture

2019

A cutting cell was developed to evaluate the texture of green asparagus by measuring its resistance to being cut with a wire. The cell was used in conjunction with a universal texturometer and improved on the single-point method of the Wilder fibrometer. Experimental conditions were determined for using the cell to measure the cutting resistance of asparagus subjected to different extents of heat treatment. Better discrimination between samples was obtained than with a Kramer cell. The fresh asparagus spears. were heated at temperatures between 70 and 100°C for different lengths of time and the kinetics of the degradation of texture was studied. A biphasic (two-component) behavior was obser…
