Dynamique et modélisation des crues dans le bassin du Mono à Nangbéto (Togo/Bénin)
2014
Les inondations des dernières années en Afrique de l'Ouest rendent nécessaire la prévision hydro-logique pour réduire la vulnérabilité des populations. Nous avons étudié la dynamique des crues dans le bassin du Mono en amont du barrage de Nangbéto (Togo et Bénin) par des méthodes statistiques et déterministes. L'augmentation des précipitations au cours de la décennie 1990 et la mise en eau du barrage de Nangbéto en 1988 ont modifié le régime du Mono, dont les débits d'étiages ont augmenté. Les débits entrants et sortants du barrage sont équivalents, même lors des crues. Les maximums annuels des débits entrants peuvent être modélisés par une distribution des valeurs extrêmes (GEV) de type Fr…
Uncertainty evaluation of design rainfall for urban flood risk analysis
2011
A reliable and long dataset describing urban flood locations, volumes and depths would be an ideal prerequisite for assessing flood frequency distributions. However, data are often piecemeal and long-term hydraulic modelling is often adopted to estimate floods from historical rainfall series. Long-term modelling approaches are time- and resource-consuming, and synthetically designed rainfalls are often used to estimate flood frequencies. The present paper aimsto assess the uncertainty of such an approach and for suggesting improvements in thedefinition of synthetic rainfall data for flooding frequency analysis. According to this aim, a multivariate statistical analysis based on a copulameth…
Language and Mind : towards a linguistic and critical study of spectacular language.
2021
He thesis focuses on a sample of written messages drawn from the daily environment. In the general framework of the relationship between language and power, the thesis consists in the analysis of written messages broadcast in daily life. The research is based on the collection of messages found on various media, including advertising displays. The thesis begins with the reception and use of the notions of newspeak and wooden tongue in their historical and contemporary context in order to show the topicality of linguistic and sociological questions about the relationship between language and power. The study of these two notions, through the linguistic and epistemological issues they involve…
A simple expression for electronic stopping force of heavy ions in solids
2012
Abstract A simple expression for the electronic stopping force of heavy ions in solids is proposed based on an adaption of the Bohr’s classical stopping theory. A three-parameter model is constructed by using experimental data for helium, oxygen, argon, krypton and xenon ions in carbon, aluminum, nickel and gold targets at energies from 600 eV/u to 985 MeV/u. Total average agreements between the model and used experimental data are (−4.5 ± 47)% and (−1.6 ± 7.4)% at energies below and above the Bragg peak, respectively. The good overall agreement makes this model a good candidate for future development in stopping force prediction tools.

Well GeHP detector calibration for environmental measurements using reference materials
2016
International audience; A well-type detector installed in the Modane underground Laboratory (LSM) can combine both low background and high detection efficiency and it is well suited for the analysis of small amounts of environmental samples. Reference materials such as IAEA-447 (moss-soil), IAEA-RG-Th1 and IAEA-RG-U1 were used for the detector calibration, owing to a chemical composition close to those of the environmental samples. Nevertheless , the matrix effects and the true coincidence summing effects must be corrected from the full energy peak efficiency (FEPE). The FEPE was performed for a wide range of energy by a semi-empirical method using Monte Carlo simulation (MCNP6), intended f…
Evolution of the longitudinal and azimuthal structure of the near-side jet peak in Pb-Pb collisions at √sNN = 2.76 TeV
2017
In two-particle angular correlation measurements, jets give rise to a near-side peak, formed by particles associated to a higher-pT trigger particle. Measurements of these correlations as a function of pseudorapidity (η) and azimuthal (ϕ) differences are used to extract the centrality and pT dependence of the shape of the near-side peak in the pT range 1 < pT < 8 GeV/c in Pb-Pb and pp collisions at √sNN = 2.76 TeV. A combined fit of the near-side peak and long-range correlations is applied to the data and the peak shape is quantified by the variance of the distributions. While the width of the peak in the ϕ direction is almost independent of centrality, a significant broadening in the η dir…
Ethnicity, 2010/3 : Russian Minorities in the Baltic States
2010
"Ethnicity" – a peer-reviewed journal was established by the Institute of Social Investigations (Daugavpils University, Latvia) and the Institute of Philosophy and Sociology (University of Latvia). The journal publishes original works about ethnicity in different fields of knowledge – sociology, history, social linguistics, social psychology, law, political science.
Developing and using tasks for the assessment of speaking
2019
This article provides an overview of the development and use of tasks for the assessment of speaking. It first addresses the key role of the assessment of the skill of speaking within language assessment in general and in the context of teaching and learning foreign languages. Then, it discusses how social changes and research have reshaped the way speaking is defined and operationalized, and focuses on how speaking can be assessed more validly and reliably today. The central role of tasks is also discussed, together with the importance of taking into consideration the implications and impact of different task characteristics. Some recommendations for the development of useful and meaningfu…
Virtual reality acceptance and commitment therapy intervention for social and public speaking anxiety : A randomized controlled trial
2023
Virtual reality (VR) offers new and flexible ways to provide psychological interventions. The aim of this study was to develop and investigate the effectiveness of a VR intervention based on acceptance and commitment therapy (ACT) for social and public speaking anxiety. ACT is a process-based approach that aims to (a) increase individuals’ abilities to handle difficult emotional and cognitive experiences and (b) develop the motivation required for change to occur. In this study, a sample of university students with social interaction or communication anxiety (N = 76; age M = 24.95, SD = 6.50, 69.7% females) was blindly randomized into a total of 2 h of VR ACT training (VRACT; n = 37) or a w…
