Utopies et medias de masse
2019
International audience; Toute technologie est portée, au moins à ses débuts, par un imaginaire.Utopies et médias de masse traite des courants utopiques qui ont cherché à considérer les médias de masse comme un levier pour une société meilleure. La perspective adoptée est à la fois historique, sociétale et éducationnelle. Elle permet d’expliquer ces courants, de les situer dans leur contexte mais aussi de saisir l’influence qu’ils ont pu avoir. Si cet ouvrage jette parfois un regard rétrospectif sur le XIXe siècle ou plus loin dans le passé, il couvre principalement le XIXe siècle. Il examine également les conditions d’une éducation aux médias de masse au XXIe siècle.L’ouvrage s’adresse aux …
Affective matching of odors and facial expressions in infants: shifting patterns between 3 and 7 months.
2016
Recognition of emotional facial expressions is a crucial skill for adaptive behavior. Past research suggests that at 5 to 7 months of age, infants look longer to an unfamiliar dynamic angry/happy face which emotionally matches a vocal expression. This suggests that they can match stimulations of distinct modalities on their emotional content. In the present study, olfaction-vision matching abilities were assessed across different age groups (3, 5 and 7 months) using dynamic expressive faces (happy vs. disgusted) and distinct hedonic odor contexts (pleasant, unpleasant and control) in a visual-preference paradigm. At all ages the infants were biased toward the disgust faces. This visual bias…
Sporta pasākumu organizācijas vietne
2022
Sports ir cilvēka dzīves neatņemama sastāvdaļa. Daudzi sporta veidi prasa noteiktu cilvēku skaitu. Bieži gadās, ka nevaram savākt vajadzīgo cilvēku skaitu. Gadās arī tā, ka trenēties vienam ir vienkārši garlaicīgi. Sporta pasākumu organizācijas vietne ir SPA (Single Page Application) lietotne, kas paredzēta sportistu savienošanai un iepazīstināšanai. Šī lietotne ļauj veidot sporta pasākumus, un lietotāji, savukārt, var tajos piedalīties. Šai lietotnei ir arī karte, kurā var atzīmēt dažāda veida sporta laukumus, piemēram, skeitparku vai tenisa kortu.

Computer Science Meets Ecology (Dagstuhl Seminar 17091)
2017
This report summarizes the program and main outcomes of the Dagstuhl Seminar 17091 entitled ``Computer Science Meets Ecolog''. Ecology is a discipline that poses many challenging problems involving big data collection, provenance and integration, as well as difficulties in data analysis, prediction and understanding. All these issues are precisely the arena where computer science is concerned. The seminar motivation was rooted in the belief that ecology could largely benefit from modern computer science. The seminar attracted scientists from both fields who discussed important topics in ecology (e.g. botany, animal science, biogeochemistry) and how to approach them with machine learning, co…
Efficient generation of restricted growth words
2013
A length n restricted growth word is a word w=w"1w"2...w"n over the set of integers where w"1=0 and each w"i, i>1, lies between 0 and the value of a word statistics of the prefix w"1w"2...w"i"-"1 of w, plus one. Restricted growth words simultaneously generalize combinatorial objects as restricted growth functions, staircase words and ascent or binary sequences. Here we give a generic generating algorithm for restricted growth words. It produces a Gray code and runs in constant average time provided that the corresponding statistics has some local properties.
Restricted compositions and permutations: from old to new Gray codes
2011
Any Gray code for a set of combinatorial objects defines a total order relation on this set: x is less than y if and only if y occurs after x in the Gray code list. Let @? denote the order relation induced by the classical Gray code for the product set (the natural extension of the Binary Reflected Gray Code to k-ary tuples). The restriction of @? to the set of compositions and bounded compositions gives known Gray codes for those sets. Here we show that @? restricted to the set of bounded compositions of an interval yields still a Gray code. An n-composition of an interval is an n-tuple of integers whose sum lies between two integers; and the set of bounded n-compositions of an interval si…
Statistics-preserving bijections between classical and cyclic permutations
2012
Recently, Elizalde (2011) [2] has presented a bijection between the set C"n"+"1 of cyclic permutations on {1,2,...,n+1} and the set of permutations on {1,2,...,n} that preserves the descent set of the first n entries and the set of weak excedances. In this paper, we construct a bijection from C"n"+"1 to S"n that preserves the weak excedance set and that transfers quasi-fixed points into fixed points and left-to-right maxima into themselves. This induces a bijection from the set D"n of derangements to the set C"n"+"1^q of cycles without quasi-fixed points that preserves the weak excedance set. Moreover, we exhibit a kind of discrete continuity between C"n"+"1 and S"n that preserves at each s…
Effect of space charge on the negative oxygen flux during reactive sputtering
2017
Negative ions often play a distinctive role in the phase formation during reactive sputter deposition. The path of these high energetic ions is often assumed to be straight. In this paper, it is shown that in the context of reactive magnetron sputtering space charge effects are decisive for the energetic negative ion trajectories. To investigate the effect of space charge spreading, reactive magnetron sputter experiments were performed in compound mode with target materials that are expected to have a high secondary ion emission yield (MgO and CeO2). By the combination of energy flux measurements, and simulations, a quantitative value for the negative oxygen ion yield can be derived.
