Roesz, Germain. "Contre l'heroique et solitaire image de l'artiste duos groupes collectifs." Strasbourg 2, 1999. http://www.theses.fr/1999STR20001.
From a catalogue of artists'duos and groups in the 20 century, the author analyses the artists' features through texts and manifestos : identities, transformations, quarrels, recurrences. The question is to differentiate the working mode between groups and duos. The question is to try an explanation of a collective creation from consciousness of separation. For ending, the author shows his own artistic attempts in this fields. Six parts are joined together in this thesis : volume 1 - taxonomy with no epilogue volume 2 ~ indexes of duos, reviews, pseudonyms (tracking list) volume 3 - index of groups volume 4 - l'epongistes volume 5 - roesz & c0 volume 6 - appendixes

Dans une première partie nous étudions plusieurs variantes du modèle PKS classique, incluant notamment une diffusion non-linéaire des cellules, ou bien une loi de diffusion chimique à noyau de Green logarithmique. Puis nous montrons l'existence globale pour une masse sous-critique du modèle PKS classique dans tout l'espace $\mathbb{R}^2$.
On complexifie ensuite le modèle de base en ajoutant un intermédiaire chimique réactionnel, ce qui modifie l'homogénéité du système. Enfin les conditions d'existence globale pour le modèle cinétique ODA avec effets délocalisants sont affaiblies par rapport aux travaux précédents.
Dans une deuxième partie nous appliquons le modèle phénoménologique de PKS, et son principe de masse critique, à un processus d'auto-organisation remarquable dans le cerveau: la sclérose concentrique de Baló. Un couplage adéquat entre un front de propagation et une instabilité de PKS décrit raisonnablement les motifs en anneaux de la maladie.
La troisième partie adopte le point de vue du transport optimal de masse pour analyser le modèle de PKS unidimensionnel modifié auparavant (afin de partager les caractéristiques de PKS 2D). Bien que la fonctionnelle d'énergie ne soit pas convexe par déplacement, nous démontrons la convergence vers un unique état d'équilibre, lorsqu'il existe. Ces nouvelles idées sont mises en oeuvre numériquement~: un flot gradient discret pour la distance de Wasserstein est analysé, puis simulé en dimension un d'espace.
Plusieurs annexes viennent compléter ce travail, dont une annexe qui regroupe tous les aspects numériques de la thèse.
Dagois, Simon. "Le chant des dunes : mouvements collectifs dans un écoulement granulaire." Paris 7, 2010. http://www.theses.fr/2010PA077081.
The song of dunes is a natural phenomenon that have arisen men's curiosity for a long time, from Marco Polo to R. A. Bagnold. Scientific observations in the XXth century have shown that the sound is emitted by a coherent vibration of the free surface of a flow in these special singing grains, and that this sound is linked to a threshold effect that depends on many parameters. In order to understand the synchronization mechanism that links the movements of the grains, we have made two missions in Morocco and in Oman to study on field these singing dunes, from which we brought back many samples. On the basis of a study of their microscopic properties, we showed that these grains are covered by a varnish that increases their friction and adhesion properties. In an experiment with varying shear rate, we characterized the threshold dependency on relative humidity as well as on flow parameters. In an avalanche experiment, we reproduced with high fidelity the song of dunes that can be heard on field and our observations showed that the flow has a part at the surface where the velocity is homogeneous like a solid movement. This experiment also showed that the synchronization is not due to an acoustic wave propagating inside the granular layer. We then developed a mode! based on the interaction between the force chains in the shear part of the flow and the plug part of the flow. This model have a good quantitative agreement with the experiments, and it also explains all the qualitative observations that have been made on this subject
Ducasse, Lauris. "Mouvements collectifs de particules en turbulence : collisions et concentration préférentielle." Nice, 2009. http://www.theses.fr/2009NICE4115.
This thesis encompasses numerical studies of problems concerning the dynamics of particles in turbulent flows. Turbulence has been modelised using a random Fourier modes method known as kinematic simulations allowing us to change the parameters of the problem for a low numerical cost. The main part of the dissertation analyses the properties of the collision rate of inertial particles in dilute systems compatible which meteorogical situations. The collision rate is estimated using a Lagrangian method recently proposed by Falkovich and Pumir (2007) and systematically compared which direct numerical measurements. The contribution of the sling effect, originally introduced by Falkovich et al. (2002), to the collision rate has been quantified following this approach. The results show that this latter is negligible in the limit of very small Stokes numbers (adimensionned relaxation time of the particles), so that the enhancement of the collision rate with respect to the case of tracers can only be explained by preferential concentration. On the other hand, the sling contribution increases sharply when the Stokes number exceeds a threshold around St = 0. 3 and can become dominant if the gravity is not too strong. A second part concerns the properties of the distributions of tracers on compressible surface flows. The second moment of these distributions has been computed explicitly in both inertial and dissipative range allowing us to quantify the fluctuations of the coarse grained concentration field (preferential concentration) with respect to the scale. The results let appear some similitudes with the case of inertial particles in incompressible flows
Seguret, Axel. "Mouvements collectifs et structure sociale chez le zebrafish en environnement fragmenté." Thesis, Sorbonne Paris Cité, 2017. http://www.theses.fr/2017USPCC168/document.
The collective decision-making is one of the mecanisms used by social species during foraging, path optimisation, collective movements, predator avoidance or habitat selection. Zebrafish (Danio rerio), gregarious animal models in biology, have never been studied in the context of collective binary choices. We found logical to analyse their decision behaviours. The goal of this thesis is to meet the expectations of the ASSISI|bf project of creation of an andjustable experimental setup able to sustain robots and fish, of development of an adaptive and self-organised mixed society and of the caracterisation of individual and collective behaviours of the zebrafish, implementable in the robots. We show that the collective decision making and the cohesion of groups of zebrafish in an open environment, composed of two identical landmarks, are dynamical processes that vary in function of the strain of Danio rerio (AB or TL) and are related to the density of the populations. Always on the move, the fish oscillate between the two landmarks. The AB zebrafish are more attracted by the landmarks and are less cohesive than the TL zebrafish. In a contrained environment, two rooms connected by a corridor, we do the same type of experiments with only AB zebrafish and vary the density of the groups from 1 to 20 individuals. AB zebrafish swim together. The increase of the density of the groups make them split. We noticed that the density of the groups has an effect on the topology of the groups : during collective departures from a room to the other one, there is a correlation between the rank of exit of the zebrafish (followers) and the rank of the distances of each individual from the initiator of the exits. This correlation is higher when the followers are either the closest or the farest from the initiator.Using the previous experimental setup, we focused also on the topics related to leadership for groups of 2 to 10 individuals. We show that each fish intiate at least once a collective departure and that the number of initiations is proportional to the number of initiation attempts. Also, we found that all the fish have the same success rate in the initiations after an initiation attempt and that there is a positive correlation between the intiations and the average speed. A deeper analysis of the collective movements shows that the zebrafish swim in group and transit without any interruption or even without periodicity between the rooms. We are currently improving this study and will bring new points of comparison to check if the non-periodicity of the transitions could be related to the density of the groups. Finally, we developed a new version of the Y-maze based on the previous observations.This perpetual Y-maze shows many usefull features for the study of the behaviour : a low habituation rate, a reduction of the interactions between the animals and the experimentators, and allows the fish to move in a Y-maze without starting nor ending zones as in typical Y-maze
Guyomar, Tristan. "Roles of acto-myosin cortex dynamics in organoid self-organisation." Electronic Thesis or Diss., Strasbourg, 2023. http://www.theses.fr/2023STRAJ100.
In this PhD study, we investigate organoids—self-assembled mini-organs derived from a few stem cells, offering a unique perspective on organogenesis. Our research links organoid shapes and collective motions to the out-of-equilibrium dynamics of the acto-myosin cortex. At the interface between Physics and Biology, we design experiments to quantify cellular and tissue properties and use theoretical physics to integrate measurements into models revealing the self-organization of organoids. Using MDCK cysts, an organotypic model, we explore (i) the role of cortical asymmetries on cell shape and cyst structure, (ii) how tight junction proteins influence cyst morphology and mechanics, and (iii) the emergence of spontaneous 3D collective rotation of cell doublets due to symmetry breaking of acto-myosin dynamics. Our work highlights the intricate link between organoid self-organisation and acto-myosin dynamics further revealing how out-of-equilibrium properties drive morphogenesis
