Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Dr. Ernst Werner (1907-1986) wurde in Lodz in der deutschen Minderheit geboren. Er studierte in Leipzig Philologie und promovierte dort 1933. Anschließend ging er nach Polen zurück und arbeitete als Gymnasiallehrer, zuerst in Lodz und dann in Lissa. Seine Haupt-Unterrichtsfächer waren Latein, Griechisch und Philosophie.Nach dem Krieg arbeitete Werner zuerst im Kultusministerium von NRW. Von 1949 bis 1957 war er dann Schulleiter am Engelbert-Kaempfer-Gymnasium in Lemgo, von 1958 bis 1960 am humanistischen Gymnasium in Bochum. Mit Ernst Schütte wechselte er nach Hessen, wo er 1960 bis 1961 das humanistische Gymnasium in Darmstadt und von 1961 bis 1970 die Ricarda-Huch-Schule in Gießen leitete.Werner war ein moderner Pädagoge (zwanzig Jahre seiner Zeit voraus), der auch immer wieder provozierte. Zu seinen markantesten Sprüchen zählte: 'Ich verbiete euch zu gehorchen', 'Ich will aus den Kindern von Nazis gute Menschen machen' und 'Wenn euch ein Lehrer schlägt, dürft ihr zurückschlagen'. Während viele seiner Schüler ihn verehrten, hatte er oft Konflikte mit konservativen Lehrern und Eltern. Schon 1988 erschien ein Buch ehemaliger Lemgoer Schüler über Ernst Werner, bezeichnenderweise mit dem Titel 'Ich verbiete euch zu gehorchen'. Das neue Buch ist eine heitere Ergänzung, mit viel neuem Material und Fotos, gerade auch über die Stationen Bochum, Darmstadt, Gießen und Wetzlar. Nach dem Lesen versteht man auch, warum Werner gelegentlich als um zwei Stufen härter bezeichnet wird als der Lehrerheld im Film 'Der Club der toten Dichter' (von 1989).

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The volume 'Storing and Transmitting Data' is based on Rudolf Ahlswede's introductory course on 'Information Theory I' and presents an introduction to Shannon Theory. Readers, familiar or unfamiliar with the technical intricacies of Information Theory, will benefit considerably from working through the book; especially Chapter VI with its lively comments and uncensored insider views from the world of science and research offers informative and revealing insights. This is the first of several volumes that will serve as a collected research documentation of Rudolf Ahlswede's lectures on information theory. Each volume includes comments from an invited well-known expert. Holger Boche contributed his insights in the supplement of the present volume.Classical information processing concerns the main tasks of gaining knowledge, storage, transmitting and hiding data. The first task is the prime goal of Statistics. For the two next, Shannon presented an impressive mathematical theorycalled Information Theory, which he based on probabilistic models. The theory largely involves the concept of codes with small error probabilities in spite of noise in the transmission, which is modeled by channels. The lectures presented in this work are suitable for graduate students in Mathematics, and also in Theoretical Computer Science, Physics, and Electrical Engineering with background in basic Mathematics. The lectures can be used as the basis for courses or to supplement courses in many ways. Ph.D. students will also find research problems, often with conjectures, that offer potential subjects for a thesis. More advanced researchers may find the basis of entire research programs.

Druck auf Anfrage Neuware - Printed after ordering - Ning Cai was an eminent mathematician, engineer and computer scientist who mademany significant contributions to information theory. In particular, his work onnetwork coding theory created a new research direction for the community.Prof. Cai's passion for science inspired his collaborators across the fields of classicaland quantum information theory, combinatorics, computation, post-Shannon theory,and coding theory, and the contributions in this volume reflect his success as a researcherand mentor.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The fourth volume of Rudolf Ahlswede's lectures on Information Theory is focused on Combinatorics. Ahlswede was originally motivated to study combinatorial aspects of Information Theory via zero-error codes: in this case the structure of the coding problems usually drastically changes from probabilistic to combinatorial. The best example is Shannon's zero error capacity, where independent sets in graphs have to be examined. The extension to multiple access channels leads to the Zarankiewicz problem.A code can be regarded combinatorially as a hypergraph; and many coding theorems can be obtained by appropriate colourings or coverings of the underlying hypergraphs. Several such colouring and covering techniques and their applications are introduced in this book. Furthermore, codes produced by permutations and one of Ahlswede's favourite research fields -- extremal problems in Combinatorics -- are presented. Whereas the first part of the book concentrateson combinatorial methods in order to analyse classical codes as prefix codes or codes in the Hamming metric, the second is devoted to combinatorial models in Information Theory. Here the code concept already relies on a rather combinatorial structure, as in several concrete models of multiple access channels or more refined distortions. An analytical tool coming into play, especially during the analysis of perfect codes, is the use of orthogonal polynomials.Classical information processing concerns the main tasks of gaining knowledge and the storage, transmission and hiding of data. The first task is the prime goal of Statistics. For transmission and hiding data, Shannon developed an impressive mathematical theory called Information Theory, which he based on probabilistic models. The theory largely involves the concept of codes with small error probabilities in spite of noise in the transmission, which is modeled by channels.

Buch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Devoted to information security, this volume begins with a short course on cryptography, mainly basedon lectures given by Rudolf Ahlswede at the University of Bielefeld in the mid1990s. It was the second of his cycle of lectures on information theory whichopened with an introductory course on basic coding theorems, as covered inVolume 1 of this series. In this third volume, Shannon's historical work onsecrecy systems is detailed, followed by an introduction to aninformation-theoretic model of wiretap channels, and such important concepts ashomophonic coding and authentication. Once the theoretical arguments have beenpresented, comprehensive technical details of AES are given. Furthermore, ashort introduction to the history of public-key cryptology, RSA and El Gamalcryptosystems is provided, followed by a look at the basic theory of ellipticcurves, and algorithms for efficient addition in elliptic curves. Lastly, theimportant topic of 'oblivious transfer' is discussed, which is stronglyconnected to the privacy problem in communication. Today, the importance ofthis problem is rapidly increasing, and further research and practical realizationsare greatly anticipated.This is the third of several volumes serving as thecollected documentation of Rudolf Ahlswede's lectures on information theory.Each volume includes comments from an invited well-known expert.
