The IceCube data acquisition system: Signal capture, digitization, and timestamping
2008
IceCube is a km-scale neutrino observatory under construction at the South Pole with sensors both in the deep ice (InIce) and on the surface (IceTop). The sensors, called Digital Optical Modules (DOMs), detect, digitize and timestamp the signals from optical Cherenkov-radiation photons. The DOM Main Board (MB) data acquisition subsystem is connected to the central DAQ in the IceCube Laboratory (ICL) by a single twisted copper wire-pair and transmits packetized data on demand. Time calibration is maintained throughout the array by regular transmission to the DOMs of precisely timed analog signals, synchronized to a central GPS-disciplined clock. The design goals and consequent features, func…
The Necessary Competences for Student Success in the First Academic Year
2013
En ligne sur : http://infonomics-society.org/IJCDSE/The%20Necessary%20Competences%20for%20Student%20Success%20in%20the%20First%20Academic%20Year.pdf; International audience; This paper tries to show which competences have an impact on the success of students in higher education and especially in the first academic year. This situation also requires finding a way to acquire the competences which are necessary in this new experience that is the first year. A student is considered to be a person who has the basic competences required. Our role is to show how this person in higher education can acquire the other new competences that help him/her attain the positive results that we name ''succes…

Shareholder Wealth Creation in Response to Announcements of Acquisitions of Unlisted Firms: Evidence from Spain
2011
We investigate shareholder value creation of Spanish listed firms in response to announcements of acquisitions of unlisted companies and compare this experience to the purchase of listed firms over the period 1991–2006. Similar to foreign markets, acquirers of listed targets earn insignificant average abnormal returns, whereas acquirers of unlisted targets gain significant positive average abnormal returns. When we relate these results to company and transaction characteristics our findings diverge from those reported in the literature for other foreign markets, as our evidence suggests that the listing status effect is mainly associated with the fact that unlisted firms tend to be smaller …
Les acquisitions scolaires des élèves au cours préparatoire : les origines des différences
1984
International audience; L’Institut de Recherche sur l’Économie de l’Éducation (ERA du CNRS), après des premières recherches sur les coûts, puis l’efficacité de l’éducation, menées dans une optique économique, a progressivement concentré son attention - entre autres - sur l’analyse du fonctionnement du système éducatif. Si les domaines de recherches se sont élargis, la méthodologie rigoureuse des premiers travaux reste bien présente, et cet article, qui relate une évaluation d’une action pédagogique, apporte autant des éléments de méthode - et de réflexion sur la méthode - que des faits, dont l’intérêt n’est pas négligeable. Les données recueillies pour cette recherche ont été collectées lor…
L'enseignement des langues vivantes à l'école élémentaire : éléments d'évaluation des effets au collège
1997
This evaluation is based on a longitudinal survey carried out over two years concerning 1 500 pupils who started secondary school. Some of them were initiated in English in the last two grades of Primary school (experimentation launched by the Ministry of Education), the other pupils had started learning English at Secondary School. Two kinds of results were obtained : first, we described a certain number of factors that influence pupils' acquisitions in English ; second, we tried to show the extent to which the outcome of early initiation explains the differences between pupils during the secondary school. It appears finally that the impact of English initiation at the Primary school seems…

Conception et réalisation d’un dispositif portatif de capteur de rayonnement PAR
2021
National audience; Dans un contexte de changement climatique et de pratiques agricoles tournées vers la préservation desressources, il devient indispensable de suivre précisément la croissance des cultures pour amener une réponserapide en cas de problèmes (stress, bio-agresseurs…). La croissance des plantes repose sur un processusbioénergétique appelé photosynthèse, elle-même stimulée par le rayonnement photosynthétiquement actif (PAR).Combinée au microclimat, cette grandeur devient également un paramètre essentiel dans certains modèles deprédiction. Cependant les coûts ou la complexité des solutions commerciales (capteurs/centrale d’acquisition) sontdes freins pouvant retarder la compréhen…
The development of L2 Italian morphosyntax in adult learners with limited literacy
2020
Low literacy and schooling rates are a significant factor among adults in the recent migration towards Europe, including Italy. However, in Italy linguistic research has paid very little attention to the relationship between newcomers’ language learning processes and (low) schooling and literacy. This lack of attention to the role of home language(s) literacy – and, more in general, to the sociolinguistic variables characterising the condition of migration – is problematic at a theoretical level. As it assumes the role of literacy as the main research question, the investigation on the acquisition of morphosyntax by adult learners with limited literacy, which is described in the volume, rep…
Repeatability of patellar cartilage thickness patterns in the living, using a fat-suppressed magnetic resonance imaging sequence with short acquisiti…
1998
A fast, reproducible, and noninvasive method is required for quantifying cartilage thickness clinically and for studying the deformation of articular cartilage during and after mechanical loading in vivo. The objective of the current investigation was to test the repeatability of regional distribution patterns of patellar cartilage thickness in the living on the basis of a fat-suppressed magnetic resonance imaging sequence with a short acquisition time and three-dimensional digital data processing. The knees of eight healthy volunteers were transversally imaged with a fat-suppressed FLASH-3D (fast low angle shot) sequence (acquisition time: 4 minutes and 10 seconds). In each case, the joint…
