Mobile robot motion planning in unstructured dynamic environments is a challenging task. Thus, often suboptimal methods are employed which perform global path planning and local obstacle avoidance separately. This work introduces a holistic planning algorithm which is based on the concept of state

Discipline en plein essor depuis 2013 en France, particulièrement prisée des médias et réseaux sociaux pour son identité visuelle spectaculaire, la course à obstacles est en train de devenir un sport d'endurance à part entière. Inspirée des parcours du combattant propres aux entraînements militaires, la course à obstacles a séduit un large public par sa dimension ludique, voire festive. Cette pratique très exigeante permet de se confronter avec soi-même en testant ses limites physiques et mentales. Que ce soit pour se dépenser sans compter, vivre une expérience inédite ou renforcer l'esprit d'équipe au sein d'un groupe, les courses à obstacles sont une épreuve dont chacun, quel que soit son niveau sportif, sort grandi. Murs, filets, barbelés, montagnes de boue, ce livre présente les outils techniques et conseils utiles à la préparation d'une course à obstacles dans de bonnes conditions. Après avoir expliqué les bienfaits de cette activité, les auteurs présentent les 5 courses emblématiques qui ont lieu en France et leurs obstacles. Une méthodologie d'entraînement ainsi que des exercices spécifiques permettront au lecteur de progresser rapidement. Emmanuel SANNA et Marion LORBLANCHET cosignent le premier ouvrage français sur les courses à obstacles avec le souci constant de donner à tous les pratiquants l'ensemble des connaissances indispensables pour devenir un finisher !

One of the most basic mathematical questions in PDE is that of regualrity. A classical example is HIlbert's XIXth problem, stated in 1900, which was solved by De Giorgi and Nash in the 1950s. The question of regularity has been a central line of research in elliptic PDE during the second half of the 20th century and has influenced many areas of mathematics linked one way or another with PDE. This text aims to provide a self-contained introduction to the regularity theory for elliptic PDE, focusing on the main ideas rather than proving all results in their greatest generality. It can be seen as a bridge between an elementary PDE course and more advanced books. The book starts with a short review of the Laplace operator and harmonic functions. The theory of Schauder estimates is developed next, but presented with various proofs of the results. Nonlinear elliptic PDE are covered in the following, both in the variational and non-variational setting and, finally, the obstacle problem is studied in detail, establishing the regularity of solutions and free boundaries.

In 2012, after Gerard Comeau had driven to Quebec to purchase cheaper beer and crossed back into New Brunswick, police officers tailed and detained him, confiscated his haul, and levied a fine. With Comeau's story as his starting point, Ryan Manucha tells the fascinating tale of Canadian interprovincial trade.
