Introduction This Goal of This Book Gaming on the move has become very popular during recent years. With the arrival of the Nintendo Gameboy, people realized that they could take their games out and about with them, and as technology has become more sophisticated these games have grown, too. They now encompass complex game mechanics, advanced 2D and 3D graphics, and engrossing stories and game worlds that the player can literally become lost in. Alongside this phenomenon is the explosion in popularity of mobile communication devices. Nearly everyone carries a phone with them every time they...

First established in August 1988, the Transaction Processing Performance Council (TPC) has shaped the landscape of modern transaction processing and database benchmarks over two decades. Now, the world is in the midst of an extraordinary information explosion led by rapid growth in the use of the Internet and connected devices. Both user-generated data and enterprise data levels continue to grow ex- nentially. With substantial technological breakthroughs, Moore's law will continue for at least a decade, and the data storage capacities and data transfer speeds will continue to increase...

At the dawn of the 21st century and the information age, communication and c- puting power are becoming ever increasingly available, virtually pervading almost every aspect of modern socio-economical interactions. Consequently, the potential for realizing a signi?cantly greater number of technology-mediated activities has emerged. Indeed, many of our modern activity ?elds are heavily dependant upon various underlying systems and software-intensive platforms. Such technologies are commonly used in everyday activities such as commuting, traf?c control and m- agement, mobile computing,...

Collections of digital documents can nowadays be found everywhere in institutions, universities or companies. Examples are Web sites or intranets. But searching them for information can still be painful. Searches often return either large numbers of matches or no suitable matches at all.

Such document collections can vary a lot in size and how much structure they carry. What they have in common is that they typically do have some structure and that they cover a limited range of topics. The second point is significantly different from documents on the Web in general.

Der Autor beschreibt die organisatorischen Voraussetzungen und alle vorbereitenden Arbeiten fur eine erfolgreiche Abnahme. Die Werkzeuge zur Durchfuhrung und fur den Abschluss werden detailliert erlautert. Berucksichtigt werden auch organisatorische Schnittstellenbereiche, die bei der Ermittlung von fachlichen und technischen Anforderungen betroffen sind.

The authors have here put together the first reference on all aspects of testing and validating service-oriented architectures. With contributions by leading academic and industrial research groups it offers detailed guidelines for the actual validation process. Readers will find a comprehensive survey of state-of-the-art approaches as well as techniques and tools to improve the quality of service-oriented applications. It also includes references and scenarios for future research and development.

"The Testing Network" presents an integrated approach to testing based on cutting-edge methodologies, processes and tools in today's IT context. It means complex network-centric applications to be tested in heterogeneous IT infrastructures and in multiple test environments (also geographically distributed). The added-value of this book is the in-depth explanation of all processes and relevant methodologies and tools to address this complexity. Main aspects of testing are explained using TD/QC - the world-leader test platform.

This up-to-date know-how is based on real-life IT...

The accelerated development of faster and cheaper electronic components faces the software designer with new challenges. One of them is to predict the viability of current architecture and the performance of current operating systems on CPUs able to operate at instruction-per-second rates about one order of magnitude higher than those available today. For this task we need to understand not only the principle of such an operating system but also the detailed mechanics and the scenario of actions determined by the random occurence of asynchronous events. Also we want to understand how this...

Network calculus is a theory dealing with queuing systems found in computer networks. Its focus is on performance guarantees. Central to the theory is the use of alternate algebras such as the min-plus algebra to transform complex network systems into analytically tractable systems. To simplify the ana- sis, another idea is to characterize tra?c and service processes using various bounds. Since its introduction in the early 1990s, network calculus has dev- oped along two tracks-deterministic and stochastic. This book is devoted to summarizing results for stochastic network calculus that can...

In den Proceedings zur 5. Internationalen GI/ITG/GMA-Tagung }ber Fehlerorientierte Rechensysteme in N}rnberg standen Tests, Diagnose und Fehlerbehandlung als Leitthemen im Mittelpunkt. Allerdings wurden auch die Themen Zuverl{ssigkeit, Verf}gbarkeit und Sicherheit in Hard- und Softwaresystemen behandelt. Der Tagungsband gibt mit eingeladenen und eingereichten Beitr{gen, die von einem internationalen Programmausschu sorgf{ltig ausgew{hlt wurden, eine ]bersicht }ber den Stand der Forschung, Entwicklung und Anwendungen aller Fehlertoleranz- und Zuverl{ssigkeitsaspekte.

Tagungsinhalt ist der Austausch neuer Ideen und Erfahrungen bei der quantitativen Untersuchung von Rechensystemen und Netzen. Dabei werden einerseits das volle methodische Spektrum (Me instrumentierung/Messung, Modellbildung/simulative und mathematische Modellanalyse, Bewertung und Synthese) in leistungsorientierter bzw. leistungs/zuverl{ssigkeitsorientierter Sicht abgedeckt, sowie andererseits }ber praktische Erfahrungen beim Einsatz dieser Methoden und Techniken bei Entwurf,...

The contributions to this book are the invited papers presented at the fifth annual Safety-critical Systems Symposium. They cover a broad spectrum of issues affecting safety, from a philosophical appraisal to technology transfer, from requirements analysis to assessment, from formal methods to artificial intelligence and psychological aspects. They touch on a number of industry sectors, but are restricted to none, for the essence of the event is the transfer of lessons and technologies between sectors. All address practical issues and of fer useful information and advice. Contributions from...

The papers contained within this volume cover a broad range of subjects. They represent a great deal of industrial...

REXX is a general purpose language which is easy to learn. It contains an extensive library of powerful functions which greatly reduces the amount of coding necessary to write applications. The use of REXX in a wide range of environments simplifies the writing of applications to run under different hardware and operating systems, and its expansibility allows other components to make sure of REXX facilities and vice versa.
Practical Usage of TSO REXX provides a concise source of information for the development and implication of applications using the REXX language. The author adopts a...

Dependability has always been an vital attribute of operational systems, regardless of whether they are highly-specialised (like electricity generating plants) or more general-purpose (like domestic appliances). This volume provides a highly-readable overview of the topic, concentrating on dependability as a life-cycle management issue rather than as a technical subject. Specifically avoiding technical language and complex mathematics, it is designed to be accessible to readers at all levels. It will be of particular interest to project managers and software engineers in industries where...
