Experimental Observation of a Large Low-Frequency Band Gap in a Polymer Waveguide
2018
The quest for large and low-frequency band gaps is one of the principal objectives pursued in a number of engineering applications, ranging from noise absorption to vibration control, and to seismic wave abatement. For this purpose, a plethora of complex architectures (including multiphase materials) and multiphysics approaches have been proposed in the past, often involving difficulties in their practical realization. To address the issue of proposing a material design that enables large band gaps using a simple configuration, in this study we propose an easy-to-manufacture design able to open large, low-frequency complete Lamb band gaps exploiting a suitable arrangement of masses and stif…
L'application du principe de laïcité à la justice
2019
Ce rapport sur « l’application de la laïcité à la justice » est le fruit d’un travail collectif mené sur deux années par une équipe d’enseignants-chercheurs (juristes et sociologues) avec le soutien de la mission de recherche « Droit et Justice ».Le sujet est d’autant plus intéressant que la justice n’est sans doute pas un service public comme les autres. Outre une laïcisation plus lente, la justice se distingue également des autres services publics par la diversité des acteurs qui s’y croisent : tous ne sont pas des professionnels (les jurés notamment) et parmi les professionnels, tous ne sont pas des agents publics. Toutes ces personnes ne sont donc pas soumises aux mêmes règles.L’essenti…

Sports teams as complex adaptive systems: manipulating player numbers shapes behaviours during football small-sided games
2016
Small-sided and conditioned games (SSCGs) in sport have been modelled as complex adaptive systems. Research has shown that the relative space per player (RSP) formulated in SSCGs can impact on emergent tactical behaviours. In this study we adopted a systems orientation to analyse how different RSP values, obtained through manipulations of player numbers, influenced four measures of interpersonal coordination observed during performance in SSCGs. For this purpose we calculated positional data (GPS 15 Hz) from ten U-15 football players performing in three SSCGs varying in player numbers (3v3, 4v4 and 5v5). Key measures of SSCG system behaviours included values of (1) players’ dispersion, (2) …
Les sources sérielles de l'étude des victimes en histoire contemporaine
1999
À l'évidence, les victimes de crimes et délits ont peu intéressé les historiens de la période contemporaine. Elles n'ont fait l'objet, en tant que telles, d'aucune recherche. L'histoire est ici un peu au diapason des autres sciences humaines, la victimologie étant une discipline toute récente dont la naissance accompagne la montée des victimes au sein du processus pénal dans les dernières décennies du xxe siècle. Encore faut-il remarquer que cette matière nouvelle déborde largement le champ t...
A Channel-Aware Adaptive Modem for Underwater Acoustic Communications
2021
Acoustic underwater channels are very challenging, because of limited bandwidth, long propagation delays, extended multipath, severe attenuation, rapid time variation and large Doppler shifts. A plethora of underwater communication techniques have been developed for dealing with such a complexity, mostly tailoring specific applications scenarios which can not be considered as one-size-fits-all solutions. Indeed, the design of environment-specific solutions is especially critical for modulations with high spectral efficiency, which are very sensitive to channel characteristics. In this paper, we design and implement a software-defined modem able to dynamically estimate the acoustic channel c…
At the interface between sensation and emotion : perceived qualities of single chords
2017
The focus of this dissertation is to investigate the perception of single chords, both in terms of perceived emotions and psychoacoustic qualities. Previous empirical research on harmony perception has mainly been concerned with horizontal aspects of harmony: studies focusing on vertical harmony perception have been rare. The current work aims to fill some of the still evident gaps between musicology, music psychology, and psychoacoustics with regard to single chord perception by combining both empirical and theoretical approaches. The work comprises three publications, based on two large-scale empirical experiments conducted with the aim of drawing the attention of both expert and inexpert…
Educación en el ordenamiento constitucional: una apuesta renovada de democracia militante (Educación para la ciudadanía y desarrollo de los valores c…
2015
La presente tesis trata de analizar en clave constitucional el diseño educativo actual en desarrollo del art. 27.2 CE, del que parte la investigación llevada a cabo sobre las facultades y previsiones que recoge el propio precepto constitucional, entre ellas las que sirvió de apoyo a la asignatura prevista en la L.O.E de 2006, la Educación para la Ciudadanía y los Derechos Humanos, y su posterior derogación por la LOMCE de 2013, acrecentando si cabe, el interés por una materia tan trascendente en el desarrollo social como es la educación. En estas coordenadas, el enfoque jurídico-constitucional realizado tiene como eje un elemento fundamental, el constituido por la descomposición analítica d…
Solidaridad y universalidad de los derechos
2019
Esta tesis aborda el principio de indivisibilidad entre la universalidad de los derechos y los deberes del ser humano apelando a un corolario: el deber de solidaridad. Para ello se analiza el sentido de la noción de solidaridad y la doble tensión en la que se mueve el concepto a través de la dicotomía público/privado y abierto/cerrado que la caracteriza, examinándose las dos dimensiones mutuamente condicionantes que lo componen: la ético-política y la jurídica. Ello nos permite examinar la problemática que encierra la configuración de la solidaridad como un valor jurídico, fuente de deberes también jurídicos, y ponderar la correspondencia entre dignidad, deberes y derechos. Así, primero se …
Soundscape design through evolutionary engines
2008
Abstract Two implementations of an Evolutionary Sound Synthesis method using the Interaural Time Difference (ITD) and psychoacoustic descriptors are presented here as a way to develop criteria for fitness evaluation. We also explore a relationship between adaptive sound evolution and three soundscape characteristics: keysounds, key-signals and sound-marks. Sonic Localization Field is defined using a sound attenuation factor and ITD azimuth angle, respectively (Ii, Li). These pairs are used to build Spatial Sound Genotypes (SSG) and they are extracted from a waveform population set. An explanation on how our model was initially written in MATLAB is followed by a recent Pure Data (Pd) impleme…
