Design of a customized pattern for improving color constancy across camera and illumination changes
2010
International audience; This paper adresses the problem of color constancy on a large image database acquired with varying digital cameras and lighting conditions. Automatic white balance control proposed by an available commercial camera is not sufficient to provide reproducible color classification. A device-independent color representation may be obtained by applying a chromatic adaptation transform, from a calibrated color checker pattern included in the field of view. Instead of using the standard Macbeth color checker, we suggest to select judicious colors to design a customized pattern from contextual information. A comparative study demonstrates that this approach insures a stronger…

Sharing practices in the digital age: inclusive processes and new citizens in the intelligent city
2015
Il modello smart city sta diventando un nuovo approccio di vita basato su processi inclusivi e pratiche innovative che coinvolgono cambiamenti correlati alle sfide delle città. I drivers (energia, mobilità, economia,etc..) della smart city sono realmente collegati dalla componente ICT che connette tutto in una logica omni-inclusiva. Attori e utilizzatori finali di queste trafsormazioni sono i cittadini, persone che con i loro smart phones diventano sensori della città recettiva e sensibile. La città in tempo reale viene analizzata attraverso mappe prodotte con sistemi GIS offrendo un altro modo di leggere le nuove funzioni urbane. E’ possibile quasi immediatamente attraverso App dedicate co…
Improving quality in clinical placement studies in nursing homes (QUALinCLINstud):the study protocol of a participatory mixed methods multiple case s…
2020
IntroductionImproved quality in clinical supervision and assessment of student nurses in nursing home clinical placements is vitally important to effective recruitment and preparation for this healthcare sector. Knowledge regarding supervision and assessment practices within these settings is limited. Also, knowledge of evolving e-learning tools on the quality and effectiveness of these educational practices seems to be absent.Methods and analysisThe aim of the “Improving quality in clinical placement studies in nursing homes” (QUALinCLINstud) study is to develop and evaluate how a web-based programme can optimise supervision, assessment and learning during nursing home placements. The stud…
On the trail of local welfare innovations in rural Finland
2019
Final Draft In Finland, the rural areas have been most affected by the developments threatening the survival of the welfare state as well as by conflicting efforts to save it. However, there are rural communities that have—as a response to the mainstream policy emphasizing economic efficiency and individual responsibility—developed innovative solutions to secure their welfare. Based on a case study focusing on two of such communities, these local welfare innovations are a result from a combination of external causes and local resources including the sense of community and a diverse enough community structure. The authors argue that in the context of welfare policy, the promotion of local we…
La jurisprudencia del Tribunal Constitucional chileno sobre tratados internacionales: el específico caso de las cláusulas autoejecutables y no autoej…
2016
El presente trabajo se pronuncia sobre el tratamiento específico que ha dado la magistratura constitucional chilena a la cuestión de las cláusulas autoejecutables y no autoejecutables de los tratados internacionales, y sobre si dicho tratamiento es adecuado conforme al sistema constitucional de incorporación y vigencia del derecho convencional internacional en el ordenamiento jurídico nacional. This paper deals with the specific treatment that has given the Constitutional Court of Chile on the question of self-executing and non-self-executing provisions of international treaties, and whether the treatment is appropriate under the constitutional system of incorporation and validity of intern…
A Non-Local Mode-I Cohesive Model for Ascending Thoracic Aorta Dissections (ATAD)
2018
This paper presents a non-local interface mechanical model to describe aortic dissection. In this regard, the mode-I debonding problem based on a cohesive zone modeling is endowed with non-local terms to include long-range interactions that are present in multi-layered biological tissue. Such non-local effects are related to the collagen fibers that transmit forces between non-adjacent elements. Numerical simulations are provided with different values of the non-local parameters in order to show the effect of the non-locality during the debonding processes.
Modèle des voies réflexes et cérébelleuses, permettant le calcul de fonctions inverses et la commande d'un segment mécanique mobile
2004
14/07/2004; La commande et le contrôle des mouvements des membres par les voies cérébelleuses et réflexes sont modélisées au moyen d'un circuit dont la structure est déduite de contraintes fonctionnelles. 1/ La première contrainte est que les mouvements rapides des membres doivent être précis, quoiqu'ils ne puissent pas être commandés en boucle fermée au moyen de signaux sensoriels. Les voies qui préparent les ordres moteurs doivent donc contenir des fonctions inverses approximées des fonctions biomécaniques du membre et des muscles. Or une telle fonction peut être calculée au moyen de boucles de rétroaction parallèles, dont la structure est comparable à l'anatomie des voies cérébelleuses. …

A dynamic adjustment model of saccade lengths in reading for word-spaced orthographies : evidence from simulations and invisible boundary experiments
2021
Contemporary models of eye movement control in reading assume a discrete target word selection process preceding saccade length computation, while the selection itself is assumed to be driven by word identification processes. However, a potentially more parsimonious, dynamic adjustment view allows both next word length and its content (e.g. orthographic) to modulate saccade length in a continuous manner. Based on a recently proposed center-based saccade length account (a new regression model of forward saccade length is introduced and validated in a simulation study. Further, additional simulations and gaze-contingent invisible boundary experiments were used to study the cognitive mechanism…
