Révision méthodologique du suivi statistique de l'emploi dans les professions vertes
No full textCe document présente la révision méthodologique du suivi statistique des emplois dans les professions dites « vertes », initiées début 2019 dans le cadre des travaux de l’Observatoire national des emplois et métiers de l’économie verte (Onemev). La mise en place de cette nouvelle méthodologie s’intègre dans le cadre des travaux de refonte de la nomenclature des professions et catégories socioprofessionnelles (PCS) de l’Insee, qui ont débuté en septembre 2018
MOSARIX: PROGRESS REPORT
No full textMOSARIX is a collaborative project between three research group in Sorbonne University to build a x-ray spectrometer (2-5 keV) portable to large scale facilities with high efficiency and good resolution. X-ray spectroscopy and coincidences experiment are planned. A prototype with a single HADP crystal with von Hamos geometry has been tested (resolution and efficiency). A fast time and position detector has been realized (patent and publication).We plan to build the spectrometer with 8 HADP (or 4) crystals under Helium atmosphere using a TimePix3 or a CCD camera. MOSARIX is a project of an x-ray spectrometer in the tender x-ray domain (2-5 keV) with high efficiency, allowing performing x-ray emission and coincidences (or covariance mapping) experiments using synchrotron radiation, XFEL, the future installation SPIRAL2/GANIL or CRYRING/FAIR. It involves 2 groups at LCPMR (Francis PENENT and Marc SIMON) and one group at INSP (Dominique VERNHET). The coincidences/covariance measurements will be between x-ray photons and ions or electrons. It would be the first time for such coincidences with energy-resolved photons. The spectrometer will be portable and will be brought to the different large-scale facilities. MOSARIX is a multi-crystal HAPG von Hamos spectrometer optimized for the 2-5 keV photon energy range. Its resolving power E/DE will be 4000. It will be equipped with a fast time and position sensitive detection system, allowing performing coincidences, or with a CCD camera. I. Scientific case and some possible experiments The accelerated development of x-ray sources, as 3 rd generation synchrotrons (and recent upgrades) or free-electron lasers, has opened new opportunities to investigate new phenomena by means of photoelectron and Auger spectroscopy, electron-ion coincidence techniques and x-ray emission. However, several processes of high scientific interests are still hard to measure; some of them require the measurement of photons with high efficiency, high resolution and even sometimes in coincidence mode. This is the purpose of MOSARIX development. As an example, we propose to revisit Resonance-Enhanced X-ray Multiple Ionization (REXMI) 1 with a significant amelioration of the detection of photons, i.e. measuring the photons not only with high efficiency and high resolution but also in coincidence with ions or electrons. This will allow accessing the involved intermediate states and obtaining a clearer image of the dynamic of the multiple ionization process. MOSARIX can also be used for the investigation of very low cross-section phenomena such as attosecond electron dynamics 2 and High-Energy Resolution Off-Resonant Spectroscopy (HEROS) 3,4. X-ray spectroscopy has also proved to be a very powerful tool to investigate quantum dynamics in heavy ions collisions with matter of whatever nature, dilute or condensed 5-7.

Brain Invaders Solo versus Collaboration: Multi-User P300-based Brain-Computer Interface Dataset (bi2014b)
No full textWe describe the experimental procedures for a dataset that we have made publicly available at https://doi.org/10.5281/zenodo.3267301 in mat and csv formats. This dataset contains electroencephalographic (EEG) recordings of 38 subjects playing in pair to the multiuser version of a visual P300-based Brain-Computer Interface (BCI) named Brain Invaders (Congedo et al., 2011). The interface uses the oddball paradigm on a grid of 36 symbols (1 Target, 35 Non-Target) that are flashed pseudo-randomly to elicit a P300 response, an evoked-potential appearing about 300ms after stimulation onset. EEG data were recorded using 32 active wet electrodes per subjects (total: 64 electrodes) during three randomized conditions (Solo1, Solo2, Collaboration). The experiment took place at GIPSA-lab, Grenoble, France, in 2014. Python code for manipulating the data is available at https://github.com/plcrodrigues/py.BI.EEG.2014b-GIPSA. The id of this database is bi2014b.Dans ce document, nous décrivons une expérimentation dont les données ont été publiées sur https://doi.org/10.5281/zenodo.3267301 aux formats mat et csv. Ce jeu de donnée contient les enregistrements électroencéphalographiques (EEG) de 38 sujets jouant par pair à une version multi-user du jeu Brain Invaders (Congedo et al., 2011), une interface cerveau-ordinateur de type ‘P300 visuel’. L’interface repose sur le paradigme oddball avec une grille de 36 symboles (1 Target, 35 Non-Target) qui clignotent de façon pseudo-aléatoire afin de produire un P300, un potentiel évoqué apparaissant environ 300ms après le début d’une stimulation. L'EEG de chaque sujet a été enregistré grâce à 32 électrodes humides réparties sur la surface du scalp (total : 64 électrodes par pair), au cours de trois session expérimentales randomisé (Solo1, Solo2, Collaboration). L'expérience a été menée au GIPSA-lab (Université de Grenoble-Alpes, CNRS, Grenoble-INP) en 2014. Nous fournissons également une implémentation python pour manipuler les données à https://github.com/plcrodrigues/py.BI.EEG.2014b-GIPSA. L’identifiant de cette base de données est bi2014b
Experimental analysis of vectorized instructions impact on energy and power consumption under thermal design power constraints
No full textInternational audienceVectorized instructions were introduced to improve the performance of applications. However, they come with an increase in the power consumption cost. As a consequence, processors are designed to limit the frequency of the processors when such instructions are used in order to maintain the thermal design power.In this paper, we study and compare the impact of thermal design power and SIMD instructions on performance, power and energy consumption of processors and memory. The study is performed on three different architectures providing different characteristics and four applications with different profiles (including one application with different phases, each phase having a different profile).The study shows that, because of processor frequency, performance and power consumption are strongly related under thermal design power. It also shows that AVX512 has unexpected behavior regarding processor power consumption, while DRAM power consumption is impacted by SIMD instructions because of the generated memory throughput
