This comprehensive field guide offers a detailed and authoritative look at the diverse flora found in the alpine regions of Europe. Written by a team of expert botanists and illustrated with over 500 full-color photographs and diagrams, The Alpine Flora provides a valuable resource for hikers, gardeners, and naturalists alike. With its detailed descriptions and informative essays on ecology, evolution, and conservation, this book is an essential reference for anyone interested in the alpine environment and its unique plant life.

Queues and stochastic networks are analyzed in this book with purely probabilistic methods. The purpose of these lectures is to show that general results from Markov processes, martingales or ergodic theory can be used directly to study the corresponding stochastic processes. Recent developments have shown that, instead of having ad-hoc methods, a better understanding of fundamental results on stochastic processes is crucial to study the complex behavior of stochastic networks. In this book, various aspects of these stochastic models are investigated in depth in an elementary way: Existence of equilibrium, characterization of stationary regimes, transient behaviors (rare events, hitting times) and critical regimes, etc. A simple presentation of stationary point processes and Palm measures is given. Scaling methods and functional limit theorems are a major theme of this book. In particular, a complete chapter is devoted to fluid limits of Markov processes.

Virtually all societies currently have to address problems of crime and insecurity. In tackling these problems most countries have emphasized repressive penal policies. In most of these countries the size of prison populations did increase, although a corresponding positive impact on public security cannot be observed. Faced with this vicious circle, the mayors of large cities in Western Europe and in North America have proclaimed in Montreal in October 1989 the necessity to adopt a policy of prevention. In November 1991 a second International Conference put the focus on the question of developing and evaluating preventive policies. The conference was preceeded by the work of a scientific committee which summarized the experiences made in various countries with crime prevention. The national reports as well as the conclusions produced during the work of the scientific committee are part of this volume which may serve as a valuable source of knowledge for all those who are interested in the prevention of crime.
