Automatic image representation for content-based access to personal photo album
2007
The proposed work exploits methods and techniques for automatic characterization of images for content-based access to personal photo libraries. Several techniques, even if not reliable enough to address the general problem of content-based image retrieval, have been proven quite robust in a limited domain such as the one of personal photo album. In particular, starting from the observation that most personal photos depict a usually small number of people in a relatively small number of different contexts (e.g. Beach, Public Garden, Indoor, Nature, Snow, City, etc...) we propose the use of automatic techniques borrowed from the fields of computer vision and pattern recognition to index imag…
Petite histoire d'une expérience innovante dans l'académie de Dijon
2015
National audience; L'objet de cet article est d'interroger la manière dont une pratique innovante naît dans un établissement scolaire, s'installe et diffuse dans d'autres établissements. En prenant appui sur la sociologie de la « traduction », de même que sur une des propositions que de nombreux travaux sociologiques tendent à conforter - notamment celle selon laquelle les acteurs opérationnels résistent fréquemment aux prescriptions venues de leur hiérarchie -, il s'agira de faire émerger ce que sont les conditions nécessaires à la nais-sance d'une expérience innovante, ainsi qu'à l'installation et la diffusion des pratiques qui se rattachent à cette expérience. Le rôle du chef d'établisse…
Deep Learning Based Cardiac MRI Segmentation: Do We Need Experts?
2021
Deep learning methods are the de facto solutions to a multitude of medical image analysis tasks. Cardiac MRI segmentation is one such application, which, like many others, requires a large number of annotated data so that a trained network can generalize well. Unfortunately, the process of having a large number of manually curated images by medical experts is both slow and utterly expensive. In this paper, we set out to explore whether expert knowledge is a strict requirement for the creation of annotated data sets on which machine learning can successfully be trained. To do so, we gauged the performance of three segmentation models, namely U-Net, Attention U-Net, and ENet, trained with dif…
ALGORITHMS FOR JUMBLED PATTERN MATCHING IN STRINGS
2011
The Parikh vector p(s) of a string s is defined as the vector of multiplicities of the characters. Parikh vector q occurs in s if s has a substring t with p(t)=q. We present two novel algorithms for searching for a query q in a text s. One solves the decision problem over a binary text in constant time, using a linear size index of the text. The second algorithm, for a general finite alphabet, finds all occurrences of a given Parikh vector q and has sub-linear expected time complexity; we present two variants, which both use a linear size index of the text.
Opinion Statement ECJ-TF 3/2019 on the CJEU Decision of 22 November 2018 in Case C-575/17, Sofina, on Withholding Taxes, Losses and Territoriality
2020
This article deals with the decision taken by the Court of Justice of the European Union in Sofina. In the authors' view, it may have extended the standard of comparability, requiring (foreign) non-dividend income of the recipient to be taken into consideration in comparing the tax treatment of domestic and outbound dividends. This comparator, however, upsets the principle of territoriality, as accepted by the Court in Futura (Case C-250/95) and Centro Equestre (Case C-345/04), by requiring the source state to take into account losses that the non-resident taxpayer has in the residence state. Taken at face value, Sofina's impact may extend well beyond withholding taxes, specifically, and di…
The overstated generational gap in online news use? A consolidated infrastructural perspective
2021
Recent research by Taneja et al. suggested that digital infrastructures diminish the generational gap in news use by counteracting preference structures. We expand on this seminal work by arguing that an infrastructural perspective requires overcoming limitations of highly aggregated web tracking data used in prior research. We analyze the individual browsing histories of two representative samples of German Internet users collected in 2012 ( N = 2970) and 2018 ( N = 2045) and find robust evidence for a smaller generational gap in online news use than commonly assumed. While short news website visits mostly demonstrated infrastructural factors, longer news use episodes were shaped more by …

Daily wellbeing in families with children: A harmonious and a disharmonious week
2014
AbstractWhat makes daily life in families with young children harmonious, and are there better and worse times? Applying a daily approach, the present study examined one week in dual-earner families with young children, with special focus on families that reported either a harmonious or a disharmonious week in their family interaction. Quantitative and qualitative diary data were collected with mobile phones and with paper and pencil from 45 families. Fourteen families representing either disharmonious or harmonious interaction were chosen for a detailed analysis of good and difficult moments in the spousal and parent–child relationship. What most clearly distinguished these weeks was not t…
