Cryptology is the art and science of secure communication over insecure channels. The primary aim of this book is to provide a self-contained overview of recent cryptologic achievements and techniques in a form that can be understood by readers having no previous acquaintance with cryptology. It can thus be used as independent reading by whoever wishes to get started on the subject. An extensive bibliography of 250 references is included to help the reader deepen his or her understanding and go beyond the topics treated here. This book can also be used as preliminary material for an...

Peer-to-peer networking is a disruptive technology for large scale distributed app- cations that has recently gained wide interest due to the successes of peer-to-peer (P2P) content sharing, media streaming, and telephony applications. There are a large range of other applications under development or being proposed. The - derlying architectures share features such as decentralizaton, sharing of end system resources, autonomy, virtualization, and self-organization. These features constitute the P2P paradigm. This handbook broadly addresses a large cross-section of c- rent research and...

I have attended quite a few conferences and meetings devoted to the ideas of Kurt Lewin. Among these the 1984 conference at Temple was out standing for its high quality. What made it so successful? Several things. The conference included a stimulating mix of generations. The first generation of women who obtained their Ph. D. 's in psychology in Berlin in the 1920's strike me as a remarkable group. Now in their 80's, they are characterized by enormous vigor and energy. They are still professionally active. Two of them - Tamara Dembo and Maria Rickers Ovsienkina - joined us. Other participants...

This book is intended to give an account of the theory of infi nitely divisible statistical experiments which started from LeCam, 1974. It includes a presentation of LeCam's basic results as well as new developments in the field. The book consists of four chapters written by different authors. Chapters I, III and IV have been prepared in Bayreuth with the support of the Deutsche Forschungsgemeinschaft (DFG); Chapter II is part of its author's Habilitationsschrift, 1982 (Dortmund). For the reader's convenience, the chapters have been unified in presentation, without neglecting differences in...

This volume represents a collection of pioneering papers introducing immunochemical techniques to the aquatic sciences. It is the product of a workshop entitled "Immunochemical Approaches to Coastal, Estuarine and Oceanographic Questions" held at the University of Southern Maine, Portland, Oct. 5-7, 1986. Funding from many sources made this workshop possible, and is gratefully acknowledged. The reader will note great variability in both the quality and scope of the papers which we have divided 'into four sections: I. Background material on the immune system (borrowed from a recent NIH...

Lying along the eastern seaboard of South Africa, the province of Natal has many important associations with the ocean. There is a considerable wealth of information available, presented by specialists from academia and state-funded research organizations. Thus, this volume provides the reader with a broad and thorough overview of the oceanography of this important region of the Southern African coastline. This volume will be of interest to a wide audience of oceanographers, marine geologists, and geographers.

This book is a slightly revised and expanded version of a set I I I of notes used for a lecture series given at the Ecole dlEte de I Probabilites at st. Flour in August 1986. In view of the statistical nature of the material discussed herein it was agreed to publish the material as a separate volume in the statistics series rather than, as is the tradition, in a joint volume in the Lecture Notes in Mathematics Series. It is a genuine pleasure to have this opportunity to thank I I I the organizers of Les Ecoles dlEte, and in particular Professor P. -L. Hennequin, for the excellent arrangements...
