Diploma Thesis from the year 2002 in the subject Computer Science - Miscellaneous, grade: 1,0, University of Applied Sciences Bielefeld (unbekannt), language: English, abstract: Inhaltsangabe:Abstract:Language learning software has been available on the market for a couple of years. So far the most common form of delivering the product is a CD-Rom. The Internet offers not only the possibility to deliver this product in an immaterial way, but also to add new features to it.The goal of the thesis is to find out, which additional features an online offered language learning software must possess, to satisfy the needs of the customer. This task is part of the so called new product development process. It is a very complex process and refers to all departments of a company, even though, for a long time it has been considered to be only the job of the R & D department. But to solve the above mentioned task, the technical component, of new product development is not important. For this piece of work only the point of view of the marketing department is important, as it is their duty to observe the market expectations. Therefore this thesis only covers the first part of new product development, the opportunity identification, and partly the design.Firstly the different environments were studied and secondary data were collected. A main part of the secondary data were delivered by a European Union study from the year 2000. This research was focused on the knowledge and habits of EU inhabitants regarding foreign languages. After the examination of the available secondary data, the required primary data were collected, to find out how the single features satisfy the requirements of the target group. Other secondary data were delivered by pedagogical departments of universities. They researched and evaluated, from the pedagogical point of view, possible online features like e-mail, newsgroups and chats, videoconferences, downloadable video / audio files and up to date articles.This thesis objective is to find out, how these possible features meet the requirements of the customer, or to be more precise of the target group. Therefore the target group had to be defined. Defined by profession, the target group consist of: Students in higher education and universities, managers and White Collar Workers.Thanks to the secondary data, the needs of the target group are known. To obtain the required primary data, on how the possible product features satisfy the market needs, a questionnaire was designed. The interviews took place in two countries and at international courses in order to be able to consider domestic differences. The universities were: The University of Applied Science, Bielefeld, Germany and the Universidade do Minho, Braga Portugal.The results were analysed and afterwards the few available offers, of online language learning products, were evaluated according to the obtained results. Resulting from this work one can state that there is a general positive attitude of the respondents regarding the new possible features, even though different attitude groups exist.The features that are considered to be the most valuable and helpful ones are E-mail, newsgroups and Chat and Downloadable Video / Audio files . At present there is not even a handful of companies, which are offering one or all of the new possible features, on the Internet. This means the entry barrier for this emerging market is still very low and that makes this market quite attractive.Inhaltsverzeichnis:Table of Contents:1.)Executive Summary42.)Introduction6a.)A General outline of the development in Europe6b.)Elearning of foreign languages7c.)The part of New Product Development83.)Literature Review9a.)Introduction9b.)Elearning from the pedagogical point of View9c.)Problems of New Product Development11i....

Maintaining a Global Communication Network

Bachelor Thesis from the year 2008 in the subject Communications - Multimedia, Internet, New Technologies, grade: 1.3, Bielefeld University, course: Politikwissenschaft, language: English, abstract: The question at heart of this paper is how society manages to maintain what has become its most important communication network, the Internet. The coordinative mechanisms necessary to achieve this are regarded as governance mechanisms. Since 'governance' is understood as a property of social systems and 'Internet infrastructure' relates to a technological system, two system/environment relations need to be observed: technology as the environment of society and society as the environment of technology. This circular system/environment relationship complicates the notion of governance, because governance (the establishment of social coordination) shapes and limits Internet architecture (the basic design principles of the Internet platform) and Internet architecture shapes and limits governance. Thus, before governance mechanisms regarding Internet infrastructure can be addressed, some preliminary considerations have to be made regarding the interaction between society and technology in general. This topic has been the subject of many academic publications covering disciplines such as sociology, political science, economics and network engineering; but the solutions proposed usually tend to either oversimplify the problem or use the jargon of complex systems to paraphrase them. The approach presented here examines the fundamental technical principles of Internet connectivity, sets them in relationship to social systems and regards 'Internet governance' as contextual intervention (Willke 1989).

With peptides playing such a valuable role in the body, the need for a modern and scientifically up-to-date advanced textbook is critical for both students and teachers. This book on peptide science distils the knowledge of hundreds of publications into a highly readable synopsis of this diverse field. Commencing with the broad fundamentals of peptide synthesis and structure, systematic explanations of the important families of biologically active peptides are given, and the interdisciplinary approach covers application areas in biotechnology, pharmaceutical science, and biomedicine. One major focus is on such 'hot' research topics as pseudopeptides, peptidomimetics, combinatorial synthesis, and proteomics. This new edition has been fully revised and now features study questions and exercises for each learning unit, didactically enhanced for easier self-study and classroom teaching. Norbert Sewald studied Chemistry at the Technical University of Munich, Germany, where he also obtained his PhD degree. After postdoctoral work with J. E. Baldwin in Oxford, UK, he became an Assitant Professor at Leipzig University. Since 1999 he is full Professor at the University of Bielefeld where he holds the chair in Organic and Bioorganic Chemistry. His main scientific interest is in peptide chemistry, bioactive peptides., and their application in biochemistry and medical sciences. He has authored more than 120 publications and together with Hans-Dieter Jakubke, has written the book Peptides from A - Z, also published by Wiley-VCH. Hans-Dieter Jakubke studied Chemistry at the Martin-Luther-University Halle-Wittenberg, Germany. After finishing his PhD and postdoctoral work with Josef Rudinger in Prague (Czeck Republic), he was appointed Assistant Professor at the Department of Biochemistry in Halle, and Full Professor of Biochemistry at the University of Leipzig in 1977. He was director of the Department of Biochemistry from 1993-1997 and member of the Council of the European Peptide Society from 1990-1994.

Hiding Data - Selected Topics
163,00 CHF *
ggf. zzgl. Versand

Devoted to information security, this volume begins with a short course on cryptography, mainly based on lectures given by Rudolf Ahlswede at the University of Bielefeld in the mid 1990s. It was the second of his cycle of lectures on information theory which opened with an introductory course on basic coding theorems, as covered in Volume 1 of this series. In this third volume, Shannon’s historical work on secrecy systems is detailed, followed by an introduction to an information-theoretic model of wiretap channels, and such important concepts as homophonic coding and authentication. Once the theoretical arguments have been presented, comprehensive technical details of AES are given. Furthermore, a short introduction to the history of public-key cryptology, RSA and El Gamal cryptosystems is provided, followed by a look at the basic theory of elliptic curves, and algorithms for efficient addition in elliptic curves. Lastly, the important topic of “oblivious transfer” is discussed, which is strongly connected to the privacy problem in communication. Today, the importance of this problem is rapidly increasing, and further research and practical realizations are greatly anticipated. This is the third of several volumes serving as the collected documentation of Rudolf Ahlswede’s lectures on information theory. Each volume includes comments from an invited well-known expert. In the supplement to the present volume, Rüdiger Reischuk contributes his insights. 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. The lectures presented in this work are suitable for graduate students in Mathematics, and also for those working in Theoretical Computer Science, Physics, and Electrical Engineering with a 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 questions which form the basis of entire research programs.

This book examines morphogenetic processes based on a combination of digital and analogue modeling and manufacturing techniques. Traditional physical modelling techniques were combined with digital 3d modelling and manufacturing technologies, informing the emerging constructs with additional components. These modules can in many cases be translated into architectural designs. They operate as precursors of architecture to come. These visual studies have been produced in the academic context of the Technical University of Darmstadt (Germany). The produced output proves not only to be an exciting new way in educational motivation and systematic architectural approach, but also serves as an important step of intruducing (future) architects into the understanding and handling of complex geometries and novel CAD / CAM technologies. Asterios Agkathidis studied architecture in the AU Thessaloniki and the RWTH Aachen, completing his postgraduate studies in Advanced Architectural Design at the Staedelschule Architecture Class (Frankfurt). He became a partner at b&k+ (Cologne), then worked for VMX architects (Amsterdam). He later founded the architecture and research laboratory a3lab Frankfurt-Thessaloniki and has been planning and realizing projects around the world since then. His work has been published, awarded and exhibited widely. His teaching and lecturing experiences include AdbK Nuremberg, TU Darmstadt, AU Thessaloniki, University of Thessaly, Bielefeld University of Applied Sciences, International Islamic University Malaysia, Columbia University and the Staedelschule Architecture Class. He was visiting assistant professor at the Lebanese American University and senior lecturer at Raffles Design Institute Shanghai. Today he holds a Lectureship for Digital Design at the University of Liverpool.
