Full textSyfte – Studiens syfte är att utöka kunskapen om hur hjulmotorstömmar kan kombineras med maskininlärning för att användas vid kollisionsdetektion hos autonoma robotar, detta för att kunna minska antalet krävda externa sensorer hos dessa robotar och på så sätt öppna upp design möjligheter samt minska produktionskostnader Metod – Studien genomfördes med design science research där två artefakter utvecklades i samarbete med Globe Tools Group. Artefakterna utvärderades sedan i hur de kategoriserade kollisioner utifrån en given datamängd som genererades från en autonom gräsklippare. Studiens experiment introducerade sedan in data som inte ingick i samma datamängd för att se hur metoderna kategoriserade detta. Resultat – Artefakterna klarade med 100% noggrannhet att detektera kollisioner i den giva datamängden som genererades. Dock har de två olika artefakterna olika beslutsregioner i hur de kategoriserar datamängderna till kollision samt icke-kollisioner, vilket kan ge dom olika användningsområden Implikationer – Examensarbetet bidrar till en ökad kunskap om hur maskininlärning och hjulmotorströmmar kan användas i ett kollisionsdetekteringssystem. Studiens resultat kan bidra till minskade kostnader i produktion samt nya design möjligheter Begränsningar – Datamängden som användes i studien samlades endast in av en autonom gräsklippare som gjorde frontalkrockar med underlaget konstgräs. Nyckelord – Maskininlärning, K-nearest neighbor, Multi-layer perceptron, kollisionsdetektion, autonoma robotar

Full textIn general, the Physics of collisions concerns the study of phenomena induced by the relative motion of interacting particles. In chemical physics and atomic physics, which are the area covered by this PhD, the interactions are Coulombic and the colliding partners are atoms or molecules which can be neutral or charged. During the collision, they are likely to undergo important modifications of their electronic environment, which can be the source of various secondary processes that are of great interest, for example, in the modelling of complex systems such as plasmas or astrophysical and biological media. Our study is based on a close-coupling semi-classical description of the multielectronic processes occurring in the course of atomic and molecular collision at impact energy such as the relative velocity of the partners are of the same order of magnitude than the classical velocity of their valence electrons. We have studied two ?benchmark? systems (H+ - Li , He ? H2+), for which we have respectively highlighted the existence of couplings between channels involving inner and outer-shell electrons of lithium, and, wave matter interferences and diffraction phenomena. We have also studied more complex colliding systems involving the carbon nucleus in analyzing multielectronic (C(+) ? He collisions) and multicentric (proton-graphene collisions) phenomena. For the latter system, the results obtained have allowed us to bring out the principles of a new two-dimensional material imaging technique

Full textThis is a study about the Navigating Mariners ability to locate and use information from the Radar and ARPA, before taking important decisions in Trafic Situations. The purpose was to acquire an understanding if there are some difficulties in receiving this important information. This purpose was accomplished by a pre-investigation using two interviews with experienced deck officers. This pre-study produced criterias, that made it possible to compare 13 Accident Reports. These reports were used as a litterature for the investigation. The Department of Transport, Marine Investigation Branch(MAIB), The Swedish Accident Investigation Board(SHK) and The Swedish Maritime Safety Inspectorate(SjöfR) had produced these reports. In addition to these reports, the author used both maritime- and aeronautical based articles in order to find more facts about the issues around the investigation. The findings showed that in half of the investigated accidents the mariners involved had used a low level of functionality before making the final decisions. It was also shown, that the ones that had used a very high level of functionality, before the accident, misinterpreted the information and failed to take the right decision in ample time before the accident.

Full textThe experimental set-up developed in Toulouse enables to control collisions between a charged thermalised mass-selected free cluster and molecules. Processes of attachement of the molecule onto the cluster and collision induced fragmentation can be studied. In order to better understand the process of attachment of a molecule onto a cluster, we have measured attachment cross-sections of alcohol molecules, methanol and ethanol, onto alcohol clusters. We have observed a similar behaviour as the one observed with water clusters, that is attachment cross-sections that are lower than the geometrical cross-section at small sizes and that converge to this geometrical cross-section at bigger sizes. This behaviour had been assigned to a dynamical effect in the case of water. This dynamical model can be extended with a good qualitative agreement to alcohol clusters. Processes of attachment and fragmentation enable to realise nanocalorimetry measurements. We have determined heat capacities and transition temperatures for protonated water clusters (H2O)nH+. They complete measurements already done for deprotonated water clusters (H2O)n-1OH-. The nature of the phase transition is discussed. The last part of this dissertation concerns collision induced fragmentation for molecules that has some biological interest : protonated uracil, bare or hydrated. Fragmentation pathways of the protonated uracil molecule has been observed. The influence of the number of water molecules on the fragmentation pattern of solvated uracil is linked to the proton affinity of the constituants and to the cluster structure

Full textSince the computer representation of real numbers is finite, an interval projective point is used to encompass all localization errors of a modeled point. An interval point is the elementary geometrical form from which all others are constructed. The Euclidean convex set spanned by an interval point is also a polytope.
The construction of a polytope relies on a robust convex hull algorithm. The computed hull is guaranteed to contain all interval projective points.
An extrusion based collision detection algorithm builds an AND-OR decision tree. Each leaf is a univariate function that expresses the relation between a moving point and a moving plane. Interval zero finding methods are applied to find the overlap and non-overlap portions of the trajectories of moving polytopes.
The swept-volume based collision detection algorithm depends on the construction of a convex approximation that comprises the real swept volume. To obtain a convex approximation, the convex hull algorithm is applied to the bounding volumes of the vertices of a moving polytope. Each bounding volume is an interval projective point.
Finally, both collision detection algorithms are tested in the context of generate-and-test path planning.

Full textWith the advances of instruments dedicated to molecular astronomy made during the past decades and forthcoming (herschel and alma), more and more molecules are discovered, and observed spectra become more and more precise. For a good understanding of these data, one needs state-to-state collisional rates for the observed molecules. The precision of rates is one of the key points of this thesis: at the same time, we seek the maximum precision and characterize the need and cost of precision in the calculations we make. Co-h2 is a system of great astrophysical interest, previously widely studied. We show on this system the equal importance of the main steps of the calculation in the final precision of the rates. On hc3n-h2, we achieve for the first time a fit of the potential energy surface (pes) on a spherical basis allowing us to carry out, also for the first time, quantum scattering calculations. Strong quantum selection rules are obtained (absent at the classical level). They should play a role in the astrophysical modeling of this molecule. These results are in principle transposable to any large linear molecule. Finally, we build for h2o-h2 a nine-dimensional pes, including all vibrations. The original and and precise fit of this surface allows us to rule on the optimal choice of geometries for rigid molecules, as well as to compute rovibrational rates. The latter, being one order of magnitude larger than the previous data, will change the interpretation of observations, notably those of the forthcoming herschel space telescope

Full textAn underlying requirement for any Autonomous Underwater Vehicle (AUV) is to navigate through unknown or partly unknown environments while performing certain user specified tasks. The loss of an AUV due to collision is unjustifiable both in terms of cost and replacement time. To prevent such an unfortunate event, one requires a robust and effective Collision Avoidance System (CAS). This paper discusses the collision avoidance problem for the HUGIN AUVs. In the first part, a complete simulator for the HUGIN AUV is implemented in matlab and simulink. This includes a 6 degrees-of-freedom nonlinear AUV model, simulated environment including bottom profile and surface ice, navigation- and guidance functionality and sensor simulators. In the second part a number of well known strategies for the collision avoidance problem is presented with a short analysis of their properties. On the basis of the implemented simulator, a proposed CAS is developed and it’s performance is analyzed. This system is based on simple principles and known collision avoidance strategies, in order to provide effective and robust performance. The proposed system provides feasible solutions during all simulations and the collision avoidance maneuvers are performed in accordance with the specified user demands. The developed simulator and collision avoidance system is expected to provide a suitable framework for further development and possibly a physical implementation on the HUGIN AUVs.

Full textDue to its position at a junction of two opposite subduction zones, the Taiwan orogen displays a structure particularly complex. This ongoing mountains building is the result of the convergence between the Philippine Sea Plate and the European Plate leading to a high seismic activity. In this context, this work was mainly focused on the seismicity of this complex collision zone. The spatial distribution of large events (M > 6) and of the background seismicity that was extracted with success from the whole earthquakes catalogue, allowed us to distinguish two main active parts, characterised by a specific seismic behaviour and located on both sides of the North-South Central Range (the main stratigraphic unit of Taiwan) with to the West the Deformation Front and to the East the Plate Boundary. For both areas we studied one recent and well instrumented seismic crisis, the Chi-Chi earthquake crisis (1999), MW 7. 6, for the western part and the Chengkung earthquake crisis (2003), MW 6. 8, for the eastern part. For the Chi-Chi earthquake (1999) we took advantage of the numerous aftershocks that followed the main event and for which focal mechanism were available. For the source area we also get events that occurred before the mainshock. Consequently we were able to depict the stress tensor evolution in space and time. In comparing the Pre- and the Post-Chi-Chi period for the two main tectonic structures involved in the crisis, we showed that the causative mountain thrust was not affected by the catastrophic event in a stress tensor point of view, even if the very source area recorded an increase of the background seismicity that extend until the end of our time period study (i. E. 2006). For the second structure, a transfer fault zone located north of the first one, we were able to illustrate the particular behaviour of a transfer fault that can change the sense of its movement as a function of the activated structures. To the East in the southern portion of the Plate Boundary, we were interested in the coseismic fault slip on the fault plane induced by the Chengkung earthquake (2003). One of the difficulties of this study was the complex geometry of the plate boundary that displays a listric shape in this area. By a simultaneously inversion of geodetic and seismological data we recovered the coseismic fault slip caused by the mainshock and its evolution during the faulting process. A unilateral southward propagation of the rupture was found with a decelerating rupture velocity with time. The rupture was unable to propagate northward during the coseismic period, but we recorded a variation of the stress state due to the mainshock during the post-seismic period and in a more north-western position than the source area, in the eastern part of the Central Range, indicating a different propagation mode of the deformation with time

Full textLa planification du mouvement connait une utilisation croissante dans le contexte industriel. Qu’elle soit destinée à la programmation des robots dans l’usine ou au calcul de l’assemblage d’une pièce mécanique, la planification au travers des algorithmes probabilistes est particulièrement efficace pour résoudre des problèmes complexes et difficiles pour l’opérateur humain. Cette thèse CIFRE, effectuée en collaboration entre le laboratoire de recherche LAAS-CNRS et la jeune entreprise Kineo CAM, s’attache à résoudre la problématique de planification de mouvement dans l’usine numérique. Nous avons identifié trois domaines auxquels s’intéressent les partenaires industriels et nous apportons des contributions dans chacun d’eux: la détection de collision, le volume balayé et le mouvement en collision. La détection de collision est un opérateur critique pour analyser des maquettes numériques. Les algorithmes de planification de mouvement font si souvent appel à cet opérateur qu’il représente un point critique pour les performances. C’est pourquoi, il existe une grande variété d’algorithmes spécialisés pour chaque type de géométries possibles. Cette diversité de solutions induit une difficulté pour l’intégration de plusieurs types de géométries dans la même architecture. Nous proposons une structure algorithmique rassemblant des types géométriques hétérogènes pour effectuer les tests de proximité entre eux. Cette architecture distingue un noyau algorithmique commun entre des approches de division de l’espace, et des tests spécialisés pour un couple de primitives géométriques donné. Nous offrons ainsi la possibilité de facilement ajouter des types de données nouveaux sans pénaliser la performance. Notre approche est validée sur un cas de robot humanoïde qui navigue dans un environnement inconnu grâce à la vision. Concernant le volume balayé, il est utilisé pour visualiser l’étendue d’un mouvement, qu’il soit la vibration d’un moteur ou le geste d‘un mannequin virtuel. L’approche la plus innovante de la littérature repose sur la puissance du matériel graphique pour calculer une approximation du volume balayé très rapidement. Elle est toutefois limitée en entrée à un seul objet, qui luimême doit décrire un volume fermé. Afin d’adapter cet algorithme au contexte de la conception numérique, nous modifions son comportement pour traiter des « soupes de polygones » ainsi que des trajectoires discontinues. Nous montrons son efficacité sur les mouvements de désassemblage pour des pièces avec un grand nombre de polygones. Il est difficile de manipuler le volume décrit par une soupe de polygones. A partir du calcul du volume balayé, nous introduisons des opérateurs qui changent la taille de l’objet discret. Ces operateurs calculent la somme de Minkowski entre l’objet et une sphère afin d’agrandir l’objet, et la différence de Minkowski pour le rétrécir. Nous obtenons les résultats sur les objets statiques ainsi que dynamiques. Enfin, nous abordons le problème de la planification de mouvement en collision. Cette antilogie exprime la capacité d’autoriser une collision bornée pendant la recherche de trajectoire. Ceci permet de résoudre certains problèmes d’assemblage très difficiles. Par exemple, lors du calcul des séquences de désassemblage, il peut être utile de permettre à des « pièces obstacles » telles que les vis de se déplacer pendant la planification. De plus, en autorisant la collision, nous sommes capables de résoudre des problèmes de passage en force. Cette problématique se pose souvent dans la maquette numérique où certaines pièces sont « souples » ou si le problème consiste à identifier la trajectoire « la moins pire » quand aucun chemin sans collision n’existe. Nous apportons dans ce travail plusieurs contributions qui s’appliquent à la conception numérique pour la robotique industrielle. Nous essayons de marier une approche scientifique avec des critères de fonctionnalités strictes pour mieux s’adapter aux utilisateurs de la conception numérique. Nous cherchons à exposer les avantages et les inconvénients de nos approches tout au long du manuscrit
