Finally the weekend! The time to escape the dense city to enjoy quieter environments? While leisure occupies a central place in our lifestyles, what is the relationship between urban styles and mobility? Are the inhabitants of city centers more mobile, seeking a greener environment in which to spend their free time? This would be the "barbecue effect," which invites stopping advocating for density and upgrading to suburban styles. This book explores this controversy by examining the cases of Geneva and Zurich, to answer some questions: Does the barbecue effect really exist? |
Enfin le week-end ! L’occasion de fuir la ville dense pour profiter d’environnements plus calmes ? Alors que les loisirs occupent une place centrale dans nos modes de vie, les déplacements induits par les loisirs des citadins sont peut-être à même de remettre fondamentalement en cause l’idée de ville compacte dont les vertus en matière de mobilité étaient jusqu’ici largement reconnues. C’est ce que suggèrent certains |

chercheurs, soulignant que les liens entre formes urbaines et mobilités n’ont été que peu abordés en prenant en compte les loisirs. Or, pour ce motif, ce sont bien les habitants des centres qui sont les plus mobiles. Selon eux, cela s’expliquerait par le fait qu’ils bénéficieraient de plus faibles possibilités de passer leur temps libre sur leur lieu de vie en comparaison avec les propriétaires de maisons avec jardin profitant d’un environnement verdoyant. Cet « effet de compensation » ou « effet barbe-cue », méconnu, inviterait dès lors à changer de paradigme : cesser de prôner la densité et revaloriser les formes périurbaines afin de réduire ce type de mobilités particulièrement polluantes. Cet ouvrage explore cette controverse en se penchant sur les cas de Ge-nève et Zurich. Son ambition est d’apporter des réponses précises aux en-jeux scientifiques et opérationnels de ce débat. L’effet barbecue existe-t-il vraiment ? Qui sont les plus grands pollueurs en matière de mobilité lorsque l’on intègre le motif loisirs ? Est-ce que la ville compacte doit être critiquée sous cet angle ? |

Sommario/riassunto |
|
This book develops a general analysis and synthesis framework for impulsive and hybrid dynamical systems. Such a framework is imperative for modern complex engineering systems that involve interacting continuous-time and discrete-time dynamics with multiple modes of operation that place stringent demands on controller design and require implementation of increasing complexity--whether advanced high-performance tactical fighter aircraft and space vehicles, variable-cycle gas turbine engines, or air and ground transportation systems. Impulsive and Hybrid Dynamical Systems goes beyond similar treatments by developing invariant set stability theorems, partial stability, Lagrange stability, boundedness, ultimate boundedness, dissipativity theory, vector dissipativity theory, energy-based hybrid control, optimal control, disturbance rejection control, and robust control for nonlinear impulsive and hybrid dynamical systems. A major contribution to mathematical system theory and control system theory, this book is written from a system-theoretic point of view with the highest standards of exposition and rigor. It is intended for graduate students, researchers, and practitioners of engineering and applied mathematics as well as computer scientists, physicists, and other scientists who seek a fundamental understanding of the rich dynamical behavior of impulsive and hybrid dynamical systems. |
