Buch. Zustand: Neu. Neuware - Coding for Channels with Feedback presents both algorithms for feedback coding and performance analyses of these algorithms, including analyses of perhaps the most important performance criterion: computational complexity. The algorithms are developed within a single framework, termed the compressed-error-cancellation framework, where data are sent via a sequence of messages: the first message contains the original data; each subsequent message contains a source-coded description of the channel distortions introduced on the message preceding it. Coding for Channels with Feedback provides an easily understood and flexible framework for deriving low-complexity, practical solutions to a wide variety of feedback communication problems. It is shown that the compressed-error-cancellation framework leads to coding schemes with the lowest possible asymptotic order of growth of computations and can be applied to discrete memoryless channels, finite state channels, channels with memory, unknown channels, and multiple-access channels, all with complete noiseless feedback, as well as to channels with partial and noisy feedback. This framework leads to coding strategies that have linear complexity and are capacity achieving, and illustrates the intimate connection between source coding theory and channel coding theory. Coding for Channels with Feedback is an excellent reference for researchers and communication engineers in the field of information theory, and can be used for advanced courses on the topic.

Buch. Zustand: Neu. Neuware - Concurrent Enterprising: Toward the Concurrent Enterprise in the Era of the Internet and Electronic Commerce presents the concurrent enterprise business model and concurrent enterprising approach, which is emerging as a crucial challenge for organizations in all geographical locations and economic sectors. To achieve this goal, this book deals with the main aspects of the merging context in which enterprises are doing business. This context is characterized by the fastest-spread information and communication technologies (ICT) that constitute the new infrastructure of the global marketplace. This book discusses a set of the most advanced enterprise paradigms created during the 1980s and 1990s, most of them supported by advanced research programs, especially in the worldwide manufacturing industry. The book discusses differences between these enterprise paradigms and presents Internet-related technologies as a main driver toward a new business model. It then examines less theoretical questions - among them, how to implement this new business model and how companies can move to the concurrent enterprise paradigm in creating a concurrent business environment. And it introduces a methodology for enterprises willing to maintain or even improve their competitiveness in the global marketplace. The book has eight chapters. The first two concentrate on the advanced enterprise paradigms, and their advantages and limits for maintaining or improving competitiveness in the global marketplace. Chapter 3 studies, separately, the virtual enterprise and related approaches. Chapter 4 studies another fundamental ingredient of the new business model - concurrent engineering (CE). Chapter 5 summarizes these preceding approaches and establishes a foundation for building a concurrent enterprise. Chapter 6 presents specific business cases illustrating the advantages and limits of virtual enterprise applications and introduces electroniccommerce and electronic documents. Chapter 7 presents concurrent enterprise as a new business model, and Chapter 8 synthesizes the concurrent enterprising process. Concurrent Enterprising: Toward the Concurrent Enterprise in the Era of the Internet and Electronic Commerce is a reference and a user's guide designed for business managers, IT managers, engineers, researchers, scientists, and other individuals interested in learning how to use a sustainable business model driven by the Internet and electronic commerce.

Buch. Zustand: Neu. Neuware - Introduction to Intelligent Simulation of Complex Discrete Systems and Processes: RAO Language focuses on a unique approach in modeling and simulation of complex systems. In this volume are considered features of complex systems and processes, their mathematical description, and modeling. Theoretical foundations of the RAO (Resource-Action-Operation) language as well as its syntax and utilisation are given. Examples of simulation models of different complexity levels, related to different fields, are also presented. The RAO intelligent modeling system, introduced and described in Introduction to Intelligent Simulation of Complex Discrete Systems and Processes is unique because: (1) it makes simulation modeling universal for the classes of systems and processes modeled; (2) it is simple to modify the models; and (3) it has the capacity to model complex control systems together with the object controlled (including simulation modeling for on-line control). The RAO tool allows the user to use a language very similar to his professional language and rids him of intermediary, supplementary description of the system modeled. In fifteen chapters this volume provides an overview of general modeling trends, and hence serves the research community in guiding their modeling methods; intelligent simulation modeling is introduced to solve complex systems and processes.

Buch. Zustand: Neu. Neuware - The Verilog hardware description language (HDL) provides the ability to describe digital and analog systems. This ability spans the range from descriptions that express conceptual and architectural design to detailed descriptions of implementations in gates and transistors. Verilog was developed originally at Gateway Design Automation Corporation during the mid-eighties. Tools to verify designs expressed in Verilog were implemented at the same time and marketed. Now Verilog is an open standard of IEEE with the number 1364. Verilog HDL is now used universally for digital designs in ASIC, FPGA, microprocessor, DSP and many other kinds of design-centers and is supported by most of the EDA companies. The research and education that is conducted in many universities is also using Verilog. This book introduces the Verilog hardware description language and describes it in a comprehensive manner. Verilog HDL was originally developed and specified with the intent of use with a simulator. Semantics of the language had not been fully described until now. In this book, each feature of the language is described using semantic introduction, syntax and examples. Chapter 4 leads to the full semantics of the language by providing definitions of terms, and explaining data structures and algorithms. The book is written with the approach that Verilog is not only a simulation or synthesis language, or a formal method of describing design, but a complete language addressing all of these aspects. This book covers many aspects of Verilog HDL that are essential parts of any design process.
