Book excerpt: Cette thèse présente l'étude d'une stratégie de coordination hybride d'un groupe de robots sous-marins pour la recherche d'objets de petites dimensions ou de singularités sur les fonds marins. Chaque robot est équipé d'un module de perception utilisant la librairie de traitement d'image OpenCV qui lui permet d'apercevoir les autres éléments de la meute ainsi que l'environnement d'évolution de la mission.Cette stratégie hybride est constituée de deux phases : une phase de mise en formation géométrique et une phase d'acquisition des données vidéo. La première phase s'appuie sur des algorithmes de type "essaims" alors que la seconde se fonde sur une méthode hiérarchique de coordination. En cas de perte de la formation, le groupe de robots quitte le mode hiérarchique et reprend le mode essaim pour se reformer. Ces changements de modes sont contrôlés par une machine à états finis. Avant d'entamer une expérimentation en grandeur nature, la méthodologie et les algorithmes de coordination doivent être testés et validés par simulation.Dans ce contexte, un simulateur basé sur le logiciel Blender a été conçu de façon à ce qu'il tienne compte des différentes contraintes liées à l'évolution des robots dans l'environnement sous-marin. Les résultats de simulation d'une meute de 3 AUVs montrent la capacité de notre stratégie à optimiser l'exécution d'une mission d'acquisition vidéo par un groupe de robots autonomes contrôlés par la vision et coordonnés par une stratégie hybride.

This book was released on 2013 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: La convergence des besoins en mission de guerre des mines et des avancées scientifiques dans le domaine de la robotique nous ont amenés à explorer une méthode innovante pour résoudre ce problème. Contrairement aux solutions de l'état de l'art, nous proposons de prendre en compte l'ensemble des contraintes opérationnelles de la mission et d'utiliser de nombreux UUV. Dans nos travaux, nous proposons une solution originale : le comportement d'essaim. Le comportement réactif des robots permet de faire émerger un comportement de groupe, effectuant la mission. Nous justifions l'approche en essaim de micro-robots par une étude technico-opérationnelle. Nous nous appuyons sur une méthode partant du général vers le particulier pour concevoir notre algorithme. Cet algorithme est capable d'aligner un essaim et de le faire progresser le long d'une trajectoire sans aucune communication. Nos résultats montrent que notre solution est robuste. L'essaim parvient à reconstituer la formation en cas de perte. La présence d'obstacles ne dégrade pas l'efficacité opérationnelle de l'essaim. L'application des méthodes en essaim à un domaine très contraint reste très peu explorée. Nous estimons que nos travaux montrent leurs capacités sur des missions complexes.

Book excerpt: Cette thèse décrit une partie du travail effectué dans le cadre du projet européen Symbrion 1 . Ce projet vise à la réalisation de tâches complexes nécessitant la coopération de multiples robots dans un cadre de robotique en essaim (au moins 100 robots opérant ensemble). De multiples problèmes sont étudiés par le projet dont : l'auto-assemblage de robots en structures complexes et l'auto-organisation d'un grand nombre de robots afin de réaliser une tâche commune. Le principal sujet porte sur les mécanismes d'auto-adaptation pour la robotique modulaire et en essaim, avec un intérêt pour des capacités de forte coordination et de coopération à l'échelle de l'essaim.Les difficultés rencontrées dans la réalisation de ce projet sont dues à l'utilisation de robots dans des environnements ouverts restant inconnus jusqu'à la phase de déploiement. Puisque les conditions d'opérations ne peuvent être prédites à l'avance, des algorithmes d'apprentissage en ligne doivent être utilisés pour élaborer les comportements utilisés. Lorsqu'un grand nombre de robots sont utilisés, plusieurs considérations doivent être prise en compte : capacité de communication réduite, faible mémoire, faible capacité de calcul. Par conséquent les algorithmes d'apprentissage en ligne doivent être distribués à travers l'essaim.De multiples approches ont déjà été proposées pour faire face aux problèmes posés par l'apprentissage en ligne décentralisé de comportements robotiques, parmi lesquels la robotique probabiliste, l'apprentissage par renforcement, et la robotique évolutionnaire. Cependant, le problème abordé dans le cadre de cette thèse se caractérise par le fait que l'on considère un groupe de robots (en lieu et place d'un seul et unique robot). De plus, dû à la nature ouverte de l'environnement, il n'est pas possible de supposer que l'ingénieur humain ait les connaissances nécessaires pour définir les éléments indispensables aux processus d'apprentissage.Assurer l'intégrité de l'essaim est placé en tant que premier élément d'une feuille de route visant à définir un ensemble d'étapes nécessaires à la réalisation d'une tâche par un groupe de robot dans un environnement ouvert :- Étape 1 : Assurer l'intégrité de l'essaim.- Étape 2 : Maintenir les robots disponibles en tant que service à l'utilisateur.- Étape 3 : Réaliser la tâche définie par l'utilisateur.Dans le cadre de cette thèse nous travaillons à la réalisation de l'étape 1 de cette feuille de route, et assumons l'hypothèse de travail suivante :Hypothèse de travail : Dans un cadre de robotique collective en environnement ouvert, la réalisation d'une tâche définie par l'utilisateur implique tout d'abord un comportement auto-adaptatif.Le sujet de cette thèse est la réalisation de solutions algorithmiques décentralisées pouvant garantir l'in- tégrité d'un essaim de robots en environnement ouvert lorsque un système robotique collectif utilise une communication locale. La principale difficulté à sa résolution est le besoin de prendre en compte l'envi- ronnement. En effet, en fonction de l'environnement courant, les robots peuvent avoir à démontrer une grande variété de comportements à l'échelle globale comme la coopération, la spécialisation, l'altruisme, ou la division du travail.Dans cette thèse nous introduisons et définissons le problème de l'Adaptation Evolutionnaire Distribuée Guidée par l'Environnement. Nous proposons un algorithme pour résoudre ce problem. Cet algorithme a été validé aussi bien en simulation que sur des robots réels. Il a été utilisé pour étudier le problème de l'auto-adaptation dans les environnements suivants :- Environnement où l'émergence de consensus comportementaux est nécessaire.- Environnements où la robustesse face à des changements environnementaux est nécessaires.- Environnements où des comportements altruistes sont nécessaires.

Available in PDF, EPUB and Kindle. Book excerpt: The essential guide by one of America's leading doctors to how digital technology enables all of us to take charge of our health A trip to the doctor is almost a guarantee of misery. You'll make an appointment months in advance. You'll probably wait for several hours until you hear "the doctor will see you now"-but only for fifteen minutes! Then you'll wait even longer for lab tests, the results of which you'll likely never see, unless they indicate further (and more invasive) tests, most of which will probably prove unnecessary (much like physicals themselves). And your bill will be astronomical. In The Patient Will See You Now, Eric Topol, one of the nation's top physicians, shows why medicine does not have to be that way. Instead, you could use your smartphone to get rapid test results from one drop of blood, monitor your vital signs both day and night, and use an artificially intelligent algorithm to receive a diagnosis without having to see a doctor, all at a small fraction of the cost imposed by our modern healthcare system. The change is powered by what Topol calls medicine's "Gutenberg moment." Much as the printing press took learning out of the hands of a priestly class, the mobile internet is doing the same for medicine, giving us unprecedented control over our healthcare. With smartphones in hand, we are no longer beholden to an impersonal and paternalistic system in which "doctor knows best." Medicine has been digitized, Topol argues; now it will be democratized. Computers will replace physicians for many diagnostic tasks, citizen science will give rise to citizen medicine, and enormous data sets will give us new means to attack conditions that have long been incurable. Massive, open, online medicine, where diagnostics are done by Facebook-like comparisons of medical profiles, will enable real-time, real-world research on massive populations. There's no doubt the path forward will be complicated: the medical establishment will resist these changes, and digitized medicine inevitably raises serious issues surrounding privacy. Nevertheless, the result-better, cheaper, and more human health care-will be worth it. Provocative and engrossing, The Patient Will See You Now is essential reading for anyone who thinks they deserve better health care. That is, for all of us.

Available in PDF, EPUB and Kindle. Book excerpt: This book analyzes the set of forces driving the global financial system toward a period of radical transformation and explores the transformational challenges that lie ahead for global and regional or local banks and other financial intermediaries. It is explained how these challenges derive from the newly emerging post-crisis structure of the market and from shadow and digital players across all banking operations. Detailed attention is focused on the impacts of digitalization on the main functions of the financial system, and particularly the banking sector. The author elaborates how an alternative model of banking will enable banks to predict, understand, navigate, and change the external ecosystem in which they compete. The five critical components of this model are data and information mastering; effective use of applied analytics; interconnectivity and “junction playing”; development of new business solutions; and trust and credibility assurance. The analysis is supported by a number of informative case studies. The book will be of interest especially to top and middle managers and employees of banks and financial institutions but also to FinTech players and their advisers and others.

Book excerpt: This prayer book was written over a two-year span. The prayers started one night when my daughter and I could not sync our time to pray together on one particular night in March 2017. While preparing for bed, the Lord said to me, "Just write a prayer and put it on Facebook". I did and the rest is history. You are now holding what it is that the Lord has done with these prayers. Each night with the exception of being away from home with no phone service, or during times of fasting, I wrote a prayer each night and posted them on Facebook. I have been told by many people along the way that they do not know how to pray. It is my prayer that this book will be a foundation for those who feel that they do not know how to pray or who simply need a prayer devotional.

Available in PDF, EPUB and Kindle. Book excerpt: Textual information in the form of digital documents quickly accumulates to create huge amounts of data. The majority of these documents are unstructured: it is unrestricted text and has not been organized into traditional databases. Processing documents is therefore a perfunctory task, mostly due to a lack of standards. It has thus become extremely difficult to implement automatic text analysis tasks. Automatic Text Summarization (ATS), by condensing the text while maintaining relevant information, can help to process this ever-increasing, difficult-to-handle, mass of information. This book examines the motivations and different algorithms for ATS. The author presents the recent state of the art before describing the main problems of ATS, as well as the difficulties and solutions provided by the community. The book provides recent advances in ATS, as well as current applications and trends. The approaches are statistical, linguistic and symbolic. Several examples are also included in order to clarify the theoretical concepts.
