Un petit garçon part en excursion dans la campagne. Sa mère va lui faire découvrir que la nature peut être source de jeux : une coque de noix devient une embarcation, un pissenlit se transforme en parachute, un coquelicot devient une poupée, etc.

This book constitutes the thoroughly refereed post-conference documentation of the Fourth International Conference on Hybrid Systems held in Ithaca, NY, USA, in October 1996. The volume presents 19 carefully revised full papers selected from numerous submissions. Hybrid systems research focuses on modeling, design, and validation of interacting systems (plants) and computer programs (control automata). This volume is devoted to hybrid systems models, formal verification, computer simulation, goal reachability, algorithms for extracting hybrid control programs, and application models for avionics, highway traffic control, and air traffic control.

"Describes the different systems that make up humans and plants: how and why they both eat, drink, and stay alive. As readers use scientific inquiry to learn about these specific living systems, an activity based on real world situations challenges them to apply what they've learned in order to solve a puzzle"--Provided by publisher.
