In today's unsafe and increasingly wired world cryptology plays a vital role in protecting communication channels, databases, and software from unwanted intruders. This revised and extended third edition of the classic reference work on cryptology now contains many new technical and biographical details. The first part treats secret codes and their uses - cryptography. The second part deals with the process of covertly decrypting a secret code - cryptanalysis, where particular advice on assessing methods is given. The book presupposes only elementary mathematical knowledge. Spiced with a wealth of exciting, amusing, and sometimes personal stories from the history of cryptology, it will also interest general readers.
The aim of this monograph is to outline the physics of image formation, electron–specimen interactions, and image interpretation in transmission el- tron microscopy. Since the last edition, transmission electron microscopy has undergone a rapid evolution. The introduction of monochromators and - proved energy ?lters has allowed electron energy-loss spectra with an energy resolution down to about 0.1 eV to be obtained, and aberration correctors are now available that push the point-to-point resolution limit down below 0.1 nm. After the untimely death of Ludwig Reimer, Dr. Koelsch from Springer- Verlag asked me if I would be willing to prepare a new edition of the book. As it had served me as a reference for more than 20 years, I agreed without hesitation. Distinct from more specialized books on speci?c topics and from books intended for classroom teaching, the Reimer book starts with the basic principles and gives a broad survey of the state-of-the-art methods, comp- mented by a list of references to allow the reader to ?nd further details in the literature. The main objective of this revised edition was therefore to include the new developments but leave the character of the book intact. The presentation of the material follows the format of the previous e- tion as outlined in the preface to that volume, which immediately follows. A few derivations have been modi?ed to correspond more closely to modern textbooks on quantum mechanics, scattering theory, or solid state physics.
Im Gegensatz zu existierenden Fachbüchern, die sich entweder ausschließlich auf die pharmakologischen Eigenschaften von pflanzlichen Naturstoffen konzentrieren oder den Sekundärstoffwechsel von Pflanzen im Rahmen der allgemeinen Pflanzenwissenschaft behandeln, deckt dieses Lehrbuch sämtliche Aspekte in einem Band ab. Es überzeugt durch Modernität, enthält farbige Abbildungen, einen Fragen- und Antwortteil und bietet Zugang zu einer begleitenden Website. Darüber hinaus liefern die einleitenden Kapitel ausreichend Hintergrundinformationen zur Chemie und Biochemie pflanzlicher Naturstoffe und deren Einsatz in der Biotechnologie. Damit ist dieses Lehrbuch in jeder Hinsicht als eigenständiges Werk in entsprechenden Kursen einsetzbar.
Long awaited by the scholarly community, Wittgenstein's so-called Big Typescript (von Wright Catalog # TS 213) is presented here in an en face English–German scholar's edition. Presents scholar's edition of important material from 1933, Wittgenstein's first efforts to set out his new thoughts after the publication of the Tractatus Logico Philosophicus Includes indications to help the reader identify Wittgenstein's numerous corrections, additions, deletions, alternative words and phrasings, suggestions for moves within the text, and marginal comments
A complete new edition of Beethoven's conversation books, now translated into English in their entirety for the first time, covering a period associated with the revolutionary style of what we call late Beethoven.
The aim of this book is to outline the physics of image formation, electron specimen interactions, imaging modes, the interpretation of micrographs and the use of quantitative modes "in scanning electron microscopy (SEM). lt forms a counterpart to Transmission Electron Microscopy (Vol. 36 of this Springer Series in Optical Sciences) . The book evolved from lectures delivered at the University of Münster and from a German text entitled Raster-Elektronenmikroskopie (Springer-Verlag), published in collaboration with my colleague Gerhard Pfefferkorn. In the introductory chapter, the principles of the SEM and of electron specimen interactions are described, the most important imaging modes and their associated contrast are summarized, and general aspects of eiemental analysis by x-ray and Auger electron emission are discussed. The electron gun and electron optics are discussed in Chap. 2 in order to show how an electron probe of small diameter can be formed, how the elec tron beam can be blanked at high frequencies for time-resolving exper iments and what problems have tobe taken into account when focusing.
This thorough treatise provides you with empirical evidence, case studies, and effective models designed to help you develop reliable programs for promoting safety among high-risk drivers. Intervening to Improve the Safety of Occupational Driving: A Behavior-Change Model and Review of Empirical Evidence is plentifully illustrated with charts and tables for easy comprehension. Researchers and practitioners in the field of organizational behavior will find valuable data about various factors in safety programs, including community agents of change, static versus dynamic goal setting, using competition to encourage change, community feedback, and effects of multiple interventions.
Incorporating significant editorial changes from earlier editions, the fourth edition of Ludwig Wittgenstein's Philosophical Investigations is the definitive en face German-English version of the most important work of 20th-century philosophy The extensively revised English translation incorporates many hundreds of changes to Anscombe’s original translation Footnoted remarks in the earlier editions have now been relocated in the text What was previously referred to as ‘Part 2’ is now republished as Philosophy of Psychology – A Fragment, and all the remarks in it are numbered for ease of reference New detailed editorial endnotes explain decisions of translators and identify references and allusions in Wittgenstein's original text Now features new essays on the history of the Philosophical Investigations, and the problems of translating Wittgenstein’s text
