Full textThis thesis is part of Cart-O-Matic project set up to participate in the challenge CARROTE (mapping of a territory) organized by the ANR and the DGA. The purpose of this challenge is to build 2D and 3D maps of a static unknown 'apartment-like' environment. In this context, the use of several robots is advantageous because it increases the time efficiency to discover fully the environment. However, as we show, the gain is determined by the level of cooperation between robots. We propose a cooperation strategy for efficient multirobot mapping. A difficulty is the construction of a common map, necessary so that each robot can know the areas of the environment which remain unexplored.For a good cooperation with a simple algorithm we propose a deployment technique based on the choice of a target by each robot. The proposed algorithm tries to distribute the robots in different directions. It is based on calculation of the partial potential fields allowing each robot to compute efficiently its next target. In addition to these theoretical contributions, we describe the complete robotic system implemented in the Cart-O-Matic team that helped win the last edition of the CARROTE challenge

Full textDans un second temps, sur la proposition d'Oliver Zobay et Barry Garraway, nous avons mis au point une nouvelle approche pour confiner les atomes dans des potentiels très anisotropes. La combinaison d'un champ radiofréquence (RF) et d'un champ magnétique statique résulte en un potentiel adiabatique dont la géométrie peut être largement contrôlée, y compris dynamiquement. Ces potentiels RF permettent de réaliser une « bulle » à atomes, un double puits, un anneau... Nous nous sommes intéressés principalement à produire un piège quasi bidimensionnel dans l'épaisseur de la bulle. Ces pièges sont compatibles avec les condensats de Bose-Einstein, et les atomes peuvent être refroidis par évaporation in situ. Nos premières expériences impliquant des champs radiofréquence ont eu un impact important dans la communauté des atomes froids, en particulier pour les expériences sur puce. A la suite de nos travaux, de nombreuses équipes ont utilisé cette technique avec succès.

Full textMany authors have used stress fields to solve the equilibrium equation of continuum me- chanics. Airy (1863) solved the two-dimensional case, Maxwell (1870) and Morera (1892) solved the three-dimensional case. The above solutions are special cases of those of Beltrami (1892). Gurtin gave an example of solutions that do not have Beltrami’s S = CurlCurlA representation. He showed that if the domain Ω is regular, then this representation is complete in the class of regular stress fields which are self-equilibrated.My thesis title is ”Characterizations of matrix fields, potential matrices and applications to trace operators”. In this work, we are interested by showing many characterizations ofvector fields, of matrix fields and especially by generalizing the result of Gurtin in the case when the open set and the stress fields are not regular.This thesis consists of five chapters. The first chapter presents the research problem ad- dressed in this thesis. It also presents the origin of the subject of research.In the second chapter, we study the operator . In particular, the existence of potential vectors in different functional frameworks.In Chapters 3 and 4, we will show some versions of Beltrami’s completeness and we deduce some Helmholtz decomopsitions for symmetric matrix fields.The last chapter is devoted to the study of the image of different trace operators of functions W 2,p (Ω), W 3,p (Ω) when Ω is a bounded open of R 2 with Lipschitz boundary. The essential ingredient is given by the Airy’s function or by the Beltrami representation

Full textLocal field potentials (LFPs) are low-frequency (< 200-500 Hz) events resulting from brain activity. Their meaning and the mechanisms shaping them have been highly debated for decades. The existence and importance of a frequency-dependant filtering of ionic currents by brain tissue is controversial. Some authors conclude that the medium is resistive, while others suggest that brain tissue may exert significative low-pass filtering on electrical currents. A new measurement method is presented here, relying on the concept of natural impedance, which is measured using a neuron as an ''electrode''. This allows to obtain the most relevant impedance from a physiological point of view, in terms of electrode-medium interface, current intensity and spatial scale. The measured impedance is stable, reproducible, stronger than what is traditionally measured, and has a 1/\√f frequency dependance. A physical model, taking into account ionic diffusion in the medium, is able to reproduce this impedance. A similar method allows to compute the transfer function between the intra- and extracellular potentials of a neuron. Models are proposed to explain its structure, predict LFPs from cell activity and vice-versa. These results may help interpreting LFP and electroencephalography signals, yielding a deeper understanding of the physiological and pathological brain function

Full textTo understand the dynamics of the neural network, neuron specificity, neural pathologies, and find new treatments, devices will have to allow a stable neural recording and multi-site stimulation with a good temporal resolution. In this thesis, we designed a flexible SU-8 implant with a high electrode density to record different regions of the cortex simultaneously. Each 15µm diameter platinum electrode of the implant is located at the end of a 11, 20 or 50 µm wide wire, free of its movements over a length of 2mm. The different sizes of the wires will further allow to evaluate the influence of dimensions on the immune response. In this thesis, the very fragile and thin implant fabrication, manipulation and connection with the recording station using a thick polyimide/copper extension and an anisotropic conductive film, were successfully achieved. The mean impedance was 810 KOhm and the mean RMS noise of electrode implants in saline solution was about 10 µV. Various surgical insertion techniques in rat cortex or agar gel (agarose 0,6%) have been studied, in particular the electrodes encapsulation in biodegradable tips or the use of a thin wire as a shuttle. Both techniques present pros and cons and should be improved in the future. Neuronal activity, such as local field potentials as well as action potentials, could be recorded in three rats implanted with the shuttle technique, demonstrating the capacity of this new type of implant in recording. Finally, in this thesis, a new method was developed to compare the performance of electrode materials commonly used to stimulate neurale tissue. It determines the injection charge capacity of an electrode by observing a change in fluorescence of a pH-sensitive dye around the electrode for different stimulation current intensities. Usual measurement tools such as impedance spectroscopy, noise recording, or evaluation of the injection charge capacity and the charge storage capacity were used as well, to check the new method reliability. This study shows that most effective materials to stimulate are the 3D nanostructured diamond and the PEDOT and highlights that when the stimulation current pulse is shorter, the current density will rather be located in the edges of the electrode

Full textNeuronal correlates of movement preparation and execution are generally studied by using tasks in which the different steps of the motor plan are triggered by stimuli. However in natural conditions, movements are rarely triggered. Time estimation processes play an important role in motor performance, but only a few studies take this fact in account. To study the influence of time estimation processes in motor cortical activity, we trained monkeys to estimate and discriminate durations in order to perform the required arm reaching movement. Movements were either self initiated or triggered by a signal. We also manipulated the probability of signal occurrence to induce signal expectancy. By using a multi-electrode device, we recorded multiple single-neuron activity and local field potentials (LFP) in primary motor cortex (MI). We found neuronal correlates of time estimation processes in motor cortical activity, such as single neuron activity, precise spike synchronizations and LFP patterns linked to signal expectancy. To better understand the relationship between spiking activity and LFPs, we also studied the correlation between the two. In general, we found that, for a given mouvement, neuronal activity is largely influenced by the temporal context of the task

Full textThe work presented in this PhD thesis promotes the idea that the resolution of complex problems can be tackled thanks to a population of simple interacting agents. The objective of this thesis is to propose a self-organized approach to solve the single and multi-level facility location problem. This kind of problem requires locating facilies considering a certain demand, in order to optimize some performance criteria. The proposed model relies on a set-organizing simple agents situated in a common environment which interact and attempt to reach a global optimization goal. The agents have neither cognitive abilites nor a representation of the global system. The interactions between agents and their environment, which are based on the artificial potential fields approach, allow to locally optimize the agent's locations. In particular, the agents' behaviors are based on a combination of attractive and repulsive forces. The facility agents are attracted to the demand to satisfy their local objectives and repulsed by each other to ensure a consistent repartition in the environment. The optimization of the whole system is the outcome of a process of agents' self-organization. Our work has several concerns : agentifying the location problem, defining the solving process, and evaluating the approach relying on qualitative and quantitative criteria. We conduct empirical studies on various case studies. These, allow to handle several variants of the location problem, especially the multi-level problem, and to check the relevance of our approach
