There are two main approaches in the theory of network error correction coding. In this SpringerBrief, the authors summarize some of the most important contributions following the classic approach, which represents messages by sequences similar to algebraic coding, and also briefly discuss the main results following the other approach, that uses the theory of rank metric codes for network error correction of representing messages by subspaces. This book starts by establishing the basic linear network error correction (LNEC) model and then characterizes two equivalent descriptions. Distances and weights are defined in order to characterize the discrepancy of these two vectors and to measure the seriousness of errors. Similar to classical error-correcting codes, the authors also apply the minimum distance decoding principle to LNEC codes at each sink node, but use distinct distances. For this decoding principle, it is shown that the minimum distance of a LNEC code at each sink node can fully characterize its error-detecting, error-correcting and erasure-error-correcting capabilities with respect to the sink node. In addition, some important and useful coding bounds in classical coding theory are generalized to linear network error correction coding, including the Hamming bound, the Gilbert-Varshamov bound and the Singleton bound. Several constructive algorithms of LNEC codes are presented, particularly for LNEC MDS codes, along with an analysis of their performance. Random linear network error correction coding is feasible for noncoherent networks with errors. Its performance is investigated by estimating upper bounds on some failure probabilities by analyzing the information transmission and error correction. Finally, the basic theory of subspace codes is introduced including the encoding and decoding principle as well as the channel model, the bounds on subspace codes, code construction and decoding algorithms.

Scientific Workflow has seen massive growth in recent years as science becomes increasingly reliant on the analysis of massive data sets and the use of distributed resources. The workflow programming paradigm is seen as a means of managing the complexity in defining the analysis, executing the necessary computations on distributed resources, collecting information about the analysis results, and providing means to record and reproduce the scientific analysis.

A major challenge in grid computing remains the application software development for this new kind of infrastructure. Grid application programmers have to take into account several complicated aspects: distribution of data and computations, parallel computations on different sites and processors, heterogeneity of the involved computers, load balancing, etc. Grid programmers thus demand novel programming methodologies that abstract over such technical details while preserving the beneficial features of modern grid middleware. For this purpose, the authors introduce Higher-Order Components (HOCs). HOCs implement generic parallel/distributed processing patterns, together with the required middleware support, and they are offered to users via a high-level service interface. Users only have to provide the application-specific pieces of their programs as parameters, while low-level implementation details, such as the transfer of data across the grid, are handled by the HOCs. HOCs were developed within the CoreGRID European Network of Excellence and have become an optional extension of the popular Globus middleware. The book provides the reader with hands-on experience, describing a broad collection of example applications from various fields of science and engineering, including biology, physics, etc. The Java code for these examples is provided online, complementing the book. The expected application performance is studied and reported for extensive performance experiments on different testbeds, including grids with worldwide distribution. The book is targeted at graduate students, advanced professionals, and researchers in both academia and industry. Readers can raise their level of knowledge about methodologies for programming contemporary parallel and distributed systems, and, furthermore, they can gain practical experience in using distributed software. Practical examples show how the complementary online material can easily be adopted in various new projects.

This brief examines current research on cooperative device-to-device (D2D) communication as an enhanced offloading technology to improve the performance of cognitive radio cellular networks. By providing an extensive review of recent advances in D2D communication, the authors demonstrate that the quality of D2D links significantly affects offloading performance in cellular networks, which motivates the design of cooperative D2D communication. After presenting the architecture of cooperative D2D communication, the challenges of capacity maximization and energy efficiency are addressed by optimizing relay assignment, power control and resource allocation. Furthermore, cooperative D2D communication is enhanced by network coding technology, and then is extended for broadcast sessions. Along with detailed problem formulation and hardness analysis, fast algorithms are developed by exploiting problem-specific characteristics such that they can be applied in practice.

Certification and Security in Inter-Organizational E-Services presents the proceedings of CSES 2004 - the 2nd International Workshop on Certification and Security in Inter-Organizational E-Services held within IFIP WCC in August 2004 in Toulouse, France. Certification and security share a common technological basis in the reliable and efficient monitoring of executed and running processes; they likewise depend on the same fundamental organizational and economic principles. As the range of services managed and accessed through communication networks grows throughout society, and given the legal value that is often attached to data treated or exchanged, it is critical to be able to certify the network transactions and ensure that the integrity of the involved computer-based systems is maintained. This collection of papers documents several important developments, and offers real-life application experiences, research results and methodological proposals of direct interest to systems experts and users in governmental, industrial and academic communities.

"Running Mainframe z on Distributed Platforms is particularly suitable for a more detailed discussion." Bill Ogden, IBM zPDT Redbook, April 2015 "The authors offer very well-reasoned solutions accompanied by case studies, which will be useful to specialists. The book is made even more useful as the System z mainframe-based solutions offer an advanced systems management environment for significant segments of data within large companies." Eugen Petac, Computing Reviews, Oct. 8, 2014 "Should you choose to implement zPDT, RDz UT, or RD&T in your team's arsenal, you will find Barrett and Norris's insights, genius, and hard work illuminating as to how to rationally and economically manage the environment." -Scott Fagen, Chief Architect-System z Business, CA Technologies "A must-read for anyone interested in successfully deploying cost-efficient zPDT environments with agility in an enterprise that requires simple or complex configurations. The case-study-based exposition of the content allows for its easy consumption and use. Excellent!" -Mahendra Durai, SVP & Information Technology Officer, CA Running Mainframe z on Distributed Platforms reveals alternative techniques not covered by IBM for creatively adapting and enhancing multi-user IBM zPDT environments so that they are more friendly, stable, and reusable than those envisaged by IBM. The enhancement processes and methodologies taught in this book yield multiple layers for system recovery, 24x7 availability, and superior ease of updating and upgrading operating systems and subsystems without having to rebuild environments from scratch. Most of the techniques and processes covered in this book are not new to either the mainframe or distributed platforms. What is new in this book are the authors' innovative methods for taking distributed environments running mainframe virtual machine (VM) and multiple virtual storage (MVS) and making them look and feel like other MVS systems.The authors' combined expertise involves every aspect of the implementation of IBM zPDT technology to create virtualized mainframe environments by which the mainframe operations on a z series server can be transitioned to distributed platforms. All of the enhancement methods consecutively laid out in this book have been architected and developed by the authors for the CA Technologies distributed platform. Barrett and Norris impart these techniques and processes to CIOs and CTOs across the mainframe and distributed fields, to zPDT and RDz UT implementers, and to IBM's independent software vendors and customers.

This book is an attempt to bring closer the greater vision of the development of Social Informatics. Social Informatics can be de?ned as a discipline of informatics that studies how information systems can realize social goals, use social concepts, or become sources of information about social phenomena. All of these research directions are present in this book: fairness is a social goal; trust is a social concept; and much of this book bases on the study of traces of Internet auctions (used also to drive social simulations) that are a rich source of information about social phenomena. The book has been written for an audience of graduate students working in the area of informatics and the social sciences, in an attempt to bridge the gap between the two disciplines. Because of this, the book avoids the use of excessive mathematical formalism, especially in Chapter 2 that attempts to summarize the theoretical basis of the two disciplines of trust and fa- ness management. Readers are usually directed to quoted literature for the purpose of studying mathematical proofs of the cited theorems.
