The practice of “incident reporting” is commonly recognized as an effective mean to reduce the vulnerability of “at risk” socio-technical systems (e.g. nuclear plants, large industrial facilities or hospitals), as it allow the concerned community to learn from past incidents. Indeed, it is assumed that collective resilience will be upgraded via the use of institutionalized Incident Reporting System (IRS), enabling the organization to improve the quality of the actions and reactions in case of deviation from normality, or to prevent such deviation. Yet, inductive analysis of what happens with those IRS in practice are not numerous. In this paper, we address this gap and display the results of semi-structured interviews conducted in a nuclear facility. During those interviews, participants were also requested to produce a mind map of the IRS they are concerned with. As a result, we show that safety is a matter of solidarities that are situated in specific contexts. To that regard, incident reporting is a practice of decomposition and recomposition of trusts and thus of solidarities. Reporting incidents consists in putting solidarity on trial, as the collective safety was threatened. We show that such open trial is often avoided because questioning solidarities is not always desirable in order to allow the group to continue functioning. Overall, we argue that informal reporting behaviors can also contribute to upgrade collective resilience without putting solidarities on trial. [less ▲]

Medications often partially alleviate the symptoms of RLS patients, emphasizing the need for finding alternative treatments. Recent studies reported an efficacy of bright light therapy (BLT) in Parkinson disease. RLS pathogenesis involves the dopaminergic system and light has been shown to influence the dopaminergic tone. Therefore, the objective of our study was to determine the therapeutic value of three weeks of BLT on RLS symptoms severity, sleep quality, daytime somnolence, circadian rhythms and mood. [less ▲]

During the two last decades, the Greenland ice sheet (GrIs) contribution to the global mean sea level (GMSL) rise has significantly increased. In the future, difficulties remain to assess the GrIs contribution to GMSL rise because of large uncertainties linked to the feedback between the surface mass balance (SMB) and the elevation of the GrIs. In 2013, Xavier Fettweis, my promoter, has coupled a regional climate model (RCM), the model MAR, with an ice sheet model (ISM), the model GRISLI, in order to account of this feedback and, in this way, to improve the assessment of the future GrIs contribution to the GMSL rise. The aim of this study is to assess the pertinence of the MAR−GRISLI coupling which requires long computation time. Nine imulations were carried out with GRISLI. Six of these simulations consisted in forcing GRISLI with several present days MAR outputs (SMB and surface temperature) in order to identify the GRISLI biases. The three last simulations consisted in forcing GRISLI until 2100 with future non-coupled, coupled and modified non- coupled MAR outputs in order to find a technique to avoid the coupling. The results show that initial conditions need to be improved and that the ice flow velocities required recalibration because an abnormal present-day thickening of the GrIs margins. Ice calving only depends on ice sheet extension because of constant ice flow velocities. The MAR−GRISLI coupling can be avoided until the middle of the 2080s. Beyond these years, the SMB correction is too large so that the thinning of the GrIs margins is overestimated. In a further study, the SMB correction could be reduced to avoid the MAR−GRISLI coupling over longer periods. GRISLI could be improved or replaced by a more complex ISM with dynamic ice flow velocities to enhance the results. [less ▲]

In this talk, I presented a joint work with Juha Honkala. We study the freeness problem for matrix semigroups. We show that the freeness problem is decidable for upper-triangular 2x2 matrices with rational entries when the products are restricted to certain bounded languages. We also show that this problem becomes undecidable for large enough matrices. [less ▲]

Improving the monitoring of rumination in cattle could help in assessing of the welfare status and their risk of acidosis. In this work, the monitoring of cattle’s behaviour was performed using the inertial measurement unit (IMU) present in smartphones mounted on the neck of cows. The processing of both time and frequency domains of the IMU signals was capable to detect accurately the main behaviours (grazing, rumination and other) and highlight the characteristics of the rumination process. The algorithm for analysis of rumination was more accurate for grazing cattle than for silage-fed cattle in stables. [less ▲]

The aim of the paper is to develop a new nonlinear tuned vibration absorber (NLTVA) capable of mitigating the vibrations of nonlinear systems which are known to exhibit frequency-energy-dependent oscillations. A nonlinear generalization of Den Hartog’s equal-peak method is proposed to ensure equal peaks in the nonlinear frequency response for a large range of forcing amplitudes. An analytical tuning procedure is developed and provides the load-deflection characteristic of the NLTVA. Based on this prescribed relation, the NLTVA design is performed by two different approaches, namely thanks to (i) analytical formulas of uniform cantilever and doubly-clamped beams and (ii) numerical shape optimization of beams with varying width and thickness. A primary system composed of a cantilever beam with a geometrically nonlinear component at its free end serves to illustrate the proposed methodology. [less ▲]

L’objectif de ce papier est de comprendre comment la médiatisation technologique et les contraintes d’utilisation d’un outil vont modifier la manière dont les agents vont mobiliser les modalités de communications pour collaborer efficacement. Dans ce travail, nous nous sommes centrés sur les références démonstratives, c’est-à-dire les références verbales qui nécessitent d’être accompagnées de gestes pour que leur interprétation soit complète. Nous avons mené cette recherche dans le domaine de la conception architecturale et avons examiné deux situations de travail collaboratif (une en coprésence et une outillée) dans le but de pouvoir les comparer. Pour chaque situation, nous décrivons comment les architectes s’adaptent aux modalités potentiellement disponibles pour désigner l’objet à quoi ils font référence dans leur discours. Nos résultats montrent que lorsque la modalité gestuelle ne peut être utilisée de manière effective, comme c’est le cas dans la situation outillée, les architectes vont développer des stratégies de compensation. En effet, la modalité graphique va pallier la transmission partielle des gestes en prenant le relais de la fonction de désignation. [less ▲]

A finite word is bordered if it has a non-empty proper prefix which is equal to its suffix, and unbordered otherwise. Ehrenfeucht and Silberger proved that an infinite word is (purely) periodic if and only if it contains only finitely many unbordered factors. We are interested in an abelian modification of this fact. Namely, we have the following question: Let w be an infinite word such that all sufficiently long factors are abelian bordered. Is w (abelian) periodic? We also consider a weakly abelian modification of this question, when only the frequencies of letters are taken into account. Besides that, we answer a question of Avgustinovich, Karhumaki and Puzynina concerning abelian central factorization theorem. [less ▲]
