Analyzing Music Services Positioning Through Qualitative Research
2015
Information technologies have produced new ways of distributing and consuming music, mainly by youth, in relation to both goods and services. In the case of goods, there has been a dramatic shift from traditional ways of buying and listening to music to new digital platforms. There has also been an evolution in relation to music services. In this sense, live music concerts have been losing their audiences over the past few years, as have music radio stations, in favor of streaming platforms. Curious about this phenomenon, we conducted an exploratory research in order to analyze how all these services, both traditional and new ones were perceived. Specifically, we aimed to study youth´s asse…

L’habitat du Néolithique final de Quinssaines, Le Bournadiau : approche spatiale et fonctionnelle d'un site au Nord-Ouest de l'Allier.
2011
A late Neolithic settlement was explored during excavations in the northeast of the Allier département, at Bournadiau near Quinsaines, in 2007. Despite erosion, the excavation revealed a ditch and traces of two buildings. The ceramic assemblage and the stone tool industry, partly imported from Grand Pressigny, illustrate the contacts between the inhabitants and the cultural groups from Western-Central (Artenac) and Northern France (Gord). An unusual deposit of seventeen Grand Pressigny flint objects, discovered in the foundations of a small building, provides information about the redistribution process of such products and shows that the site probably functioned in collaboration with the G…
Hydrothermal co-liquefaction of sewage sludge and formic acid
2019
The biocrude produced by non-catalytic hydrothermal liquefaction (HTL) has a too high heteroatom content to be used directly as a fuel [1-3]. Several studies found that different H2 initial pressures during HTL experiments were ineffective in improving the biocrude yield [4-6], nevertheless it was observed that higher initial pressures of H2 brought an improvement of the concentration of light compounds in the biocrude, decreasing the average molecular weight of biocrude oil. To date H2 is mainly generated from fossil sources and realization of a possible hydrogen economy from alternative sources presents many challenges. The use of a liquid hydrogen storage media could represent for the HT…
Shape identification in inverse medium scattering problems with a single far-field pattern
2016
Consider time-harmonic acoustic scattering from a bounded penetrable obstacle $D\subset {\mathbb R}^N$ embedded in a homogeneous background medium. The index of refraction characterizing the material inside $D$ is supposed to be Holder continuous near the corners. If $D\subset {\mathbb R}^2$ is a convex polygon, we prove that its shape and location can be uniquely determined by the far-field pattern incited by a single incident wave at a fixed frequency. In dimensions $N \geq 3$, the uniqueness applies to penetrable scatterers of rectangular type with additional assumptions on the smoothness of the contrast. Our arguments are motivated by recent studies on the absence of nonscattering waven…
Caractérisation des céramiques à bioclastes de la Protohistoire dans l’ouest de la France.
2015
The study of the ceramics from the site of the Batterie Basse in the region of Manche, shows again that the presence of bioclasts in the clays of protohistoric ceramics is a very common phenomenon in Normandy unlike in Brittany, where in the current state of knowledge only one individual from the Iron Age has been described. These bioclasts, mostly fragments of bivalves, are non-plastic elements naturally present in the clays, either in the form of fossils, either in the form of contemporary shells, or are incorporated by the craftsmans after being pounded to modify the technical characteristics of the clays. The aim of this work is to awareness the archaeologists to this type of artefacts …

Projet SOFT
2020
Le projet SOFT, sobriété énergétique par les formes urbaines et le transport, a abordé la question de la stratégieénergétique d’un territoire à l’aide d’un concept d’aménagement multi-échelle utilisant la géométrie fractale. Eneffet, les gains d’efficience classique (rénovation du bâti, performance des modes de transport, production localed’énergie) ne suffisent pas aujourd’hui pour assurer aux territoires une trajectoire carbone appropriée. Il estnécessaire de s’appuyer sur la sobriété énergétique, approche qui consiste à assurer la même qualité de vie auxhabitants, mais avec une baisse des consommations énergétiques qui peut s’accompagner d’une évolution despratiques. L’approche de la sob…
Nouvelles technologies et aide à la compréhension de documents techniques : Construction et expérimentation d'un simulateur de fonctionnement de grue…
2001
Reading skills are more and more required to succeed professional examination. French crane drivers are concerned with this problem. In order to help them, we have conducted a study with three main steps. First, we carried out a cognitive work analysis. Second, we test several analogical modalities of written presentations focusing on the construction of a specific simulator. Finally, two experiments are presented showing a significative effect of this simulator on the comprehension of cranes technical documentation.
