Communities have built collections of information in a collaborative manner for centuries. Around 250 years ago, more than 140 people wrote l’Encyclopedie in 28 volumes with 70,000 articles. More recently, Wikipedia has demonstrated how collaborative efforts can be a powerful method of building a massive data storage. It is...

Event-based distributed systems are playing an ever increasing role in areas such as enterprise management, information dissemination, finance, environmental monitoring and geo-spatial systems. Event-based processing originated with the introduction of Event-Condition-Action (ECA) rules to database systems in the 1980s. Since then,...

Service-Oriented Computing (SOC) allows software development time to be shortened by the composition of existing services across the Internet. Further exploitation of this revolutionary trend is feasible through automation, thanks to the use of software agents and techniques from distributed artificial intelligence. This book provides an...

Increased levels of chip integration combined with physical limitations of heat removal devices, cooling mechanisms and battery capacity, have established energy-efficiency as an important design objective in the implementation flow of modern electronic products. To meet these low energy objectives, new low power techniques, including...

Steganography and steganalysis, the hiding and detection of a covert payload within an innocent cover object, started to receive attention from the computer science, engineering, and mathematics communities in the 1990s. At first the problems were not clearly defined, but proper statistical foundations were proposed and mathematical...

All students interested in researching the Internet are living in very interesting and exciting times. From the Internet’s beginning in the 1960s up to the present day, the Internet has grown to become a vast platform where there are now 2 billion users of this global infrastructure.1 Predictions are that this number will rise to...

The history of software development paradigms suggests that a new paradigm often has its genesis in programming languages and then moves up to design and analysis (e.g., structured programming preceded structured design and analysis, and objectoriented programming predated object-oriented design and modeling). This same pattern can...

This volume contains the proceedings of the 6th International Conference on Logical Aspects of Computational Linguistics 2011 (LACL 2011), held June 29- July 1, 2011 in Montpellier, France. The LACL conferences aim at providing a forum for the presentation and discussion of current research in all the formal and logical aspects of...

This volume contains revised versions of selected papers presented at the biennial meeting of the Classification and Data Analysis Group (CLADAG) of the Italian Statistical Society, which was held in Macerata, September 12–14, 2007. Carlo Lauro chaired the Scientific Programme Committee and Francesco Palumbo chaired the Local...

This is not a book about algorithms . Certainly, it is full of algorithms , but that 's not what this book is about . This book is about possibilities . Its purpose is to present you not only with the prerequisite mandatory knowledge of the available problem-solving techniques , but more importantly to expand your ability to frame...

This volume contains the proceedings of the 17th International Conference on Tools and Algorithms for the Construction and Analysis of Systems (TACAS 2011). TACAS 2011 took place in Saarbr¨ucken, Germany, March 28–31, 2011, as part of the 14th European Joint Conferences on Theory and Practice of Software (ETAPS 2011), whose...

In the last decade there has been a growing interest in the research and software industry communities toward techniques, methods and tools that allow one to manage system performance concerns in the software developer domain. Poor performance can often be the cause of software project failure, and the need to address performance...
