TGV Rhin-Rhône branche sud : l'introuvable débat public
2007
Ouvert au début de l'année 2000, le débat public concernant la future ligne TGV Rhin-Rhône a été le quatrième organisé dans le cadre de la loi Barnier de 1995 par la CNDP. Ce débat a été marqué par une succession d'ambiguïtés et un contexte politico-administratif qui ont fortement altéré sa pertinence. Initié dans l'urgence, il n'a conduit début 2007 à aucune décision quant au lancement des études ni bien sûr à aucune assurance sur sa réalisation. Cet échec patent, tant dans les procédures suivies que dans ses résultats, a néanmoins été instructif : il a peut-être joué un rôle précurseur dans la révision des procédures de débats publics dans la nouvelle loi relative à la démocratie de proxi…
CasuHal : HAL Open Access Repository Users Group
2018
CasuHal is a team of volunteers, gathered into a non-profit organisation. Its purpose is to foster exchanges and communication among its 270+ members, to help them understand and take ownership of the HAL platform, and to propose the functional developments needed for a full institutional use.
Relative Effectiveness of Direct Instruction vs. Active Learning in the Teaching of Science
2013
International audience; This study compares two controversial pedagogy [5], [6], [8], [11]: direct instruction and active learning. As “performance” still used by teacher and institution as assessment indicator we have went measuring it in this research. Then, we question on effectiveness of two learning methods on acquisition of scientific knowledge. Direct instruction and active learning are there same impact in teaching of sciences? Must we choose between these two methods or use both? Scientific knowledge is it single assessment indicator?Results of this work would show that direct instruction mobilizes especially memory strategy even though active learning mobilizes more conceptual str…
Blessures et sentiments : les poèmes de Sinéad Morrissey
2018
This paper explores the poetry of Sinéad Morrissey (born in Portadown, Northern Ireland, in 1972), one of the most highly regarded of the younger generation of contemporary Irish poets. Taking into account her six collections to date – including There Was Fire in Vancouver (1996), The State of the Prisons (2005), Parallax (2013) and On Balance published in 2017, it examines the great variety of poetical strategies – analogy, metaphor, polysemy, play on form and perspective, pictorialism and iconicity, ekphrasis, etc. – that Morrissey uses to tell of most personal experiences (physical pain, exile, loss, pregnancy and motherhood, confrontation with forms of otherness, states of imprisonment,…
Ceramique/metal component elaborated by flash sintering for ballistic protection
2012
This dissertation describes the synthesis of new components for ballistic protection with the assistance of flash sintering. Indeed, the objective is to associate two compounds showing very different sintering temperatures – such as alumina and aluminum, two reference materials for ballistic protection applications.The first synthesis method tested was the elaboration of a bi-material via the sintering of aluminump owder on alumina bulks. This study permitted to observe the formation of the alumina/aluminum bonding by scanning and transmission electron microscopy and to optimize the assembly parameters in order to obtain a bimaterials howing a strong interfacial cohesion. Adapted characteri…
Frequency Stability Measurement of Cryogenic Sapphire Oscillators with a Multichannel Tracking DDS and the Two-Sample Covariance
2018
This article shows the first measurement of three 100 MHz signals exhibiting fluctuations from 2E-16 to parts in 1E-15 for integration time tau between 1 s and 1 day. Such stable signals are provided by three Cryogenic Sapphire Oscillators (CSOs) operating at about 10 GHz, also delivering the 100 MHz output via a dedicated synthesizer. The measurement is made possible by a 6-channel Tracking DDS (TDDS) and the two-sample covariance tool, used to estimate the Allan variance. The use of two TDDS channels per CSO enables high rejection of the instrument background noise. The covariance outperforms the Three-Cornered Hat (TCH) method in that the background converges to zero "out of the box," wi…
Combining omnidirectional vision with polarization vision for robot navigation
2012
Polarization is the phenomenon that describes the oscillations orientations of the light waves which are restricted in direction. Polarized light has multiple uses in the animal kingdom ranging from foraging, defense and communication to orientation and navigation. Chapter (1) briefly covers some important aspects of polarization and explains our research problem. We are aiming to use a polarimetric-catadioptric sensor since there are many applications which can benefit from such combination in computer vision and robotics specially robot orientation (attitude estimation) and navigation applications. Chapter (2) mainly covers the state of art of visual based attitude estimation.As the unpol…
The Individual-level Productivity Costs of Physical Inactivity
2023
Abstract Purpose: This study estimated the long-term individual-level productivity costs of physical inactivity. Methods: The data were drawn from the Northern Finland Birth Cohort 1966, to which the productivity cost variables (sick leaves and disability pensions) from Finnish registries were linked. Individuals (N = 6261) were categorized into physical activity groups based on their level of physical activity, which was measured in three ways: 1) self-reported leisure-time moderate- to vigorous-intensity physical activity (MVPA) at 46 yr old, 2) longitudinal self-reported leisure-time MVPA at 31–46 yr old, and 3) accelerometer-measured overall MVPA at 46 yr old. The human capital approach…
