Taschenbuch. Condizione: Neu. Neuware -This volume constitutes the refereed proceedings of the Third International Conference on Internationalization, Design and Global Development,IDGD 2009, held in San Diego, CA, USA, in July 2009 in the framework of the 13th International Conference on Human-Computer Interaction, HCII 2009 with10 other thematically similar conferences.The57 revised papers presented were carefully reviewed and selected from numerous submissions. The papers accepted for presentation thoroughly cover the entire field of internationalization, design and global development and address the following major topics: cross-cultural user interface design; culture, community, collaboration and learning; internationalization and usability; ICT for global development;and designing for eCommerce, eBusiness and eBanking. 526 pp. Englisch.…

Taschenbuch. Condizione: Neu. Neuware - Electronic voting has a young and attractive history, both in the design of basic cryptographic methods and protocols and in the application by communities who are in the vanguard of technologies. The crucial aspect of security for electronic voting systems is subject to research by computer scientists as well as by legal, social and political scientists. The essential question is how to provide a trustworthy base for secure electronic voting, and hence how to prevent accidental or malicious abuse of electronic voting in elections. To address this problem, Volkamer structured her work into four parts: 'Fundamentals' provides an introduction to the relevant issues of electronic voting. 'Requirements' contributes a standardized, consistent, and exhaustive list of requirements for e-voting systems. 'Evaluation' presents the proposal and discussion of a standardized evaluation methodology and certification procedure called a core Protection Profile. Finally, 'Application' describes the evaluation of two available remote electronic voting systems according to the core Protection Profile.The results presented are based on theoretical considerations as well as on practical experience. In accordance with the German Society of Computer Scientists, Volkamer succeeded in specifying a 'Protection Profile for a Basic Set of Security Requirements for Online Voting Products,' which has been certified by the German Federal Office for Security in Information Technology. Her book is of interest not only to developers of security-critical systems, but also to lawyers, security officers, and politicians involved in the introduction or certification of electronic voting systems.…

Buch. Condizione: Neu. Neuware -Dynamics is what characterizes virtually all phenomenae we face in the real world, and processes that proceed in practically all kinds of inanimate and animate systems, notably social systems. For our purposes dynamics is viewed as time evolution of some characteristic features of the phenomenae or processes under consideration. It is obvious that in virtually all non-trivial problems dynamics can not be neglected, and should be taken into account in the analyses to, first, get insight into the problem consider, and second, to be able to obtain meaningful results.A convenient tool to deal with dynamics and its related evolution over time is to use the concept of a dynamic system which, for the purposes of this volume can be characterized by the input (control), state and output spaces, and a state transition equation. Then, starting from an initial state, we can find a sequence of consecutive states (outputs) under consecutive inputs (controls). That is, we obtain a trajectory. The state transition equation may be given in various forms, exemplified by differential and difference equations, linear or nonlinear, deterministic or stochastic, or even fuzzy (imprecisely specified), fully or partially known, etc. These features can give rise to various problems the analysts may encounter like numerical difficulties, instability, strange forms of behavior (e.g. chaotic), etc.This volume is concerned with some modern tools and techniques which can be useful for the modeling of dynamics. We focus our attention on two important areas which play a key role nowadays, namely automation and robotics, and biological systems. We also add some new applications which can greatly benefit from the availability of effective and efficient tools for modeling dynamics, exemplified by some applications in security systems. 192 pp. Englisch.…

Taschenbuch. Condizione: Neu. Neuware -The 13th International Conference on Human-Computer Interaction, HCI Inter- tional 2009, was held in San Diego, California, USA, July 19-24, 2009, jointly with the Symposium on Human Interface (Japan) 2009, the 8th International Conference on Engineering Psychology and Cognitive Ergonomics, the 5th International Conference on Universal Access in Human-Computer Interaction, the Third International Conf- ence on Virtual and Mixed Reality, the Third International Conference on Internati- alization, Design and Global Development, the Third International Conference on Online Communities and Social Computing, the 5th International Conference on Augmented Cognition, the Second International Conference on Digital Human Mod- ing, and the First International Conference on Human Centered Design. A total of 4,348 individuals from academia, research institutes, industry and gove- mental agencies from 73 countries submitted contributions, and 1,397 papers that were judged to be of high scientific quality were included in the program. These papers - dress the latest research and development efforts and highlight the human aspects of the design and use of computing systems. The papers accepted for presentation thoroughly cover the entire field of human-computer interaction, addressing major advances in knowledge and effective use of computers in a variety of application areas. 649 pp. Englisch.…
