This book is designed for a professional audience composed of practitioners and researchers in industry. It is also suitable for advanced-level students in computer science.

Networks on Chip presents a variety of topics, problems and approaches with the common theme to systematically organize the on-chip communication in the form of a regular, shared communication network on chip, an NoC for short.

As the number of processor cores and IP blocks integrated on a single chip is steadily growing, a systematic approach to design the communication infrastructure becomes necessary. Different variants of packed switched on-chip networks have been proposed by several groups during the past two years. This book summarizes the state of the art of these efforts and discusses the major issues from the physical integration to architecture to operating systems and application interfaces. It also provides a guideline and vision about the direction this field is moving to. Moreover, the book outlines the consequences of adopting design platforms based on packet switched network. The consequences may in fact be far reaching because many of the topics of distributed systems, distributed real-time systems, fault tolerant systems, parallel computer architecture, parallel programming as well as traditional system-on-chip issues will appear relevant but within the constraints of a single chip VLSI implementation.

The book is organized in three parts. The first deals with system design and methodology issues. The second presents problems and solutions concerning the hardware and the basic communication infrastructure. Finally, the third part covers operating system, embedded software and application. However, communication from the physical to the application level is a central theme throughout the book.

The book serves as an excellent reference source and may be used as a text for advanced courses on the subject.

Android development is hot, and many programmers are interested in joining the fun. However, because this technology is based on Java, you should first obtain a solid grasp of the Java language and its foundational APIs to improve your chances of succeeding as an Android app developer. After all, you will be busy learning the architecture of an Android app, the various Android-specific APIs, and Android-specific tools. If you do not already know Java fundamentals, you will probably end up with a massive headache from also having to quickly cram those fundamentals into your knowledge base. Learn Java for Android Development teaches programmers of any skill level the essential Java language and foundational Java API skills that must be learned to improve the programmer's s chances of succeeding as an Android app developer. Each of the book's 10 chapters provides an exercise section that gives you the opportunity to reinforce your understanding of the chapter's s material. Answers to the book's s more than 300 exercises are provided in an appendix.Once you complete this book, you will be ready to dive into Android, and you can start that journey by obtaining a copy of Beginning Android 2. Additionally, author Jeff Friesen will provide supplementary material (such as 6 more chapters) on his javajeff.mb.ca website, available over the next few months following this book's release. What you'll learn * The Java language: This book provides complete coverage of nearly every pre-Java version 7 language feature (native methods are briefly mentioned but not formally covered). Starting with those features related to classes and objects, you progress to object-oriented features related to inheritance, polymorphism, and interfaces. You then explore the advanced language features for nested types, packages, static imports, exceptions, assertions, annotations, generics, and enums. Continuing, you investigate strictfp, class literals, synchronized, volatile, the enhanced for loop statement, autoboxing/unboxing, and transient fields. The book also briefly presents most (if not all) of Java version 7's language features, although not much is said about closures or modules (which were not finalized at the time of writing).* Java APIs: In addition to Object and APIs related to exceptions, you explore Math, StrictMath, BigDecimal, BigInteger, Package, Boolean, Character, Byte, Short, Integer, Long, Float, Double, Number, the References API, the Reflection API, String, StringBuffer, System, the Threading API, the collections framework, the concurrency utilities, the internationalization APIs, the Preferences API, Random, the Regular Expressions API, File, RandomAccessFile, stream classes, and writer/reader classes. You will also get a tiny taste of Swing in the context of internationalization. * Tools: You will learn how to use the JDK's javac (compiler), java (application launcher), javadoc (Java documentation generator), and jar (Java archive creator, updater, and extractor) tools. You will also receive an introduction to the NetBeans and Eclipse integrated development environments. Although you can develop Android apps without NetBeans or Eclipse, working with these IDEs is much more pleasant.Who this book is for This book is for any programmer (including existing Java programmers and Objective-C (iPhone/iPad) programmers) of any skill level who needs to obtain a solid understanding of the Java language and foundational Java APIs before jumping into Android app development.

Design of complex artifacts and systems requires the cooperation of multidisciplinary design teams using multiple sophisticated commercial and non-commercial engine- ing tools such as CAD tools, modeling, simulation and optimization software, en- neering databases, and knowledge-based systems. Individuals or individual groups of multidisciplinary design teams usually work in parallel and independently with various engineering tools, which are located on different sites, often for quite a long period of time. At any moment, individual members may be working on different versions of a design or viewing the design from various perspectives, at different levels of details. In order to meet these requirements, it is necessary to have efficient comput- supported collaborative design systems. These systems should not only automate in- vidual tasks, in the manner of traditional computer-aided engineering tools, but also enable individual members to share information, collaborate, and coordinate their activities within the context of a design project. Based on close international collaboration between the University of Technology of Compiegne in France and the Institute of Computing Technology of the Chinese Ac- emy of Sciences in the early 1990s, a series of international workshops on CSCW in Design started in 1996. In order to facilitate the organization of these workshops, an International Working Group on CSCW in Design (CSCWD) was established and an International Steering Committee was formed in 1998. The series was converted to int- national conferences in 2000 building on the success of the four previous workshops."

Computinghasbeenanenormousacceleratortoscienceandindustryalikeandit has led to an information explosion in many di?erent ?elds. The unprecedented volume of data acquired from sensors, derived by simulations and data analysis processes, accumulated in warehouses, and often shared on the Web, has given risetoanew?eldofresearch: provenancemanagement.Provenance(alsoreferred to as audit trail, lineage, and pedigree) captures information about the steps used to generate a given data product. Such information provides important documentation that is key to preserving data, to determining the data's quality and authorship, to understanding, reproducing, as well as validating results. Provenancemanagement has become an active ?eld of research, as evidenced byrecentspecializedworkshops, surveys, andtutorials.Provenancesolutionsare needed in many di?erent domains and applications, from environmental science and physics simulations, to business processes and data integration in wa- houses. Not surprisingly, di?erent techniques and provenance models have been proposed in many areas such as work?ow systems, visualization, databases, d- ital libraries, and knowledge representation. An important challenge we face - dayishowtointegratethesetechniquesandmodelssothatcompleteprovenance can be derived for complex data products. The InternationalProvenanceand AnnotationWorkshop(IPAW 2008)wasa follow-up to previous workshopsin Chigago (2006, 2002)and Edinburgh (2003). It was held during June 17-18, in Salt Lake City, at the University of Utah campus. IPAW 2008 brought together computer scientists from di?erent areas and provenance users to discuss open problems related to the provenance of computational and non-computational artifacts. A total of 55 people attended the workshop.

The Workshop on Self-sustaining Systems (S3) is a forum for the discussion of topics relating to computer systems and languages that are able to bootstrap, implement, modify, and maintain themselves. One property of these systems is that their implementation is based onsmall but powerfulabstractions;examples include (amongst others) Squeak/Smalltalk, COLA, Klein/Self, PyPy/Python, Rubinius/Ruby, andLisp.Suchsystemsaretheenginesoftheirownreplacement, giving researchers and developers great power to experiment with, and explore future directions from within, their own small language kernels. S3 took place on May 15-16, 2008 at the Hasso-Plattner-Institute (HPI) in Potsdam, Germany. It was an exciting opportunity for researchers and prac- tioners interested in self-sustaining systems to meet and share their knowledge, experience, and ideas for future research and development. S3 provided an - portunity for a community to gather and discuss the need for self-sustainability in software systems, and to share and explore thoughts on why such systems are needed and how they can be created and deployed. Analogies were made, for example, with evolutionary cycles, and with urban design and the subsequent inevitable socially-driven change. TheS3participantsleftwithagreatersenseofcommunityandanenthusiasm for probing more deeply into this subject. We see the need for self-sustaining systems becoming critical not only to the developer's community, but to e- users in business, academia, learning and play, and so we hope that this S3 workshop will become the ?rst of many.

As software systems become increasingly ubiquitous, issues of dependability become ever more crucial. Given that solutions to these issues must be considered from the very beginning of the design process, it is reasonable that dependability and security are addressed at the architectural level. This book has originated from an effort to bring together the research communities of software architectures, dependability and security.

This state-of-the-art survey contains expanded and peer-reviewed papers based on the carefully selected contributions to two workshops: the Workshop on Architecting Dependable Systems (WADS 2008), organized at the 2008 International Conference on Dependable Systems and Networks (DSN 2008), held in Anchorage, Alaska, USA, in June 2008, and the Third International Workshop on Views On Designing Complex Architectures (VODCA 2008) held in Bertinoro, Italy, in August 2008. It also contains invited papers written by recognized experts in the area. The 13 papers are organized in topical sections on dependable service-oriented architectures, fault-tolerance and system evaluation, and architecting security.

Information and communication technologies are advancing fast. Processing speed is still increasing at a high rate, followed by advances in digital storage technology, which double storage capacity every year. Furthermore, communication techno- gies do not lag behind. The Internet has been widely used, as well as wireless te- nologies. With a few mouse clicks, people can communicate with each other around the world. All these advances have great potential to change the way people live, introducing new concepts like ubiquitous computing and ambient intelligence. Technology is becoming present everywhere in the form of smart and sensitive c- puting devices. They are nonintrusive, transparent and hidden in the background, but they collect, process, and share all kinds of information, including user beh- ior, in order to act in an intelligent and adaptive way. These emerging technologies put new requirements on security and data m- agement. As data are accessible anytime anywhere, it becomes much easier to get unauthorized data access. Furthermore, the use of new technologies has brought about some privacy concerns. It becomes simpler to collect, store, and search personal information, thereby endangering people's privacy. Therefore, research in secure data management is gaining importance, attracting the attention of both the data management and the security research communities. The intere- ing problems range from traditional topics, such as, access control and general database security, via privacy protection to new research directions, such as cryptographically enforced access control.

The application of formal methods to security protocol analysis has attracted increasing attention in the past two decades, and recently has been sh- ing signs of new maturity and consolidation. The development of these formal methodsismotivatedbythehostilenatureofsomeaspectsofthenetworkand the persistent e?orts of intruders, and has been widely discussed among - searchers in this ?eld. Contributions to the investigation of novel and e?cient ideas and techniques have been made through some important conferences and journals, such asESORICS, CSFW andACM Transactions in Computer Systems. Thus, formal methods have played an important role in a variety of applications such as discrete system analysis for cryptographic protocols, - lief logics and state exploration tools. A complicated security protocol can be abstractedasamanipulationofsymbolsandstructurescomposedbysymbols. The analysis of e-commerce (electronic commerce) protocols is a particular case of such symbol systems. There have been considerable e?orts in developing a number of tools for ensuring the security of protocols, both specialized and general-purpose, such as belief logic and process algebras. The application of formal methods starts with the analysis of key-distribution protocols for communication between two principals at an early stage. With the performance of transactions - coming more and more dependent on computer networks, and cryptography becoming more widely deployed, the type of application becomes more varied and complicated. The emerging complex network-based transactions such as ?nancial transactionsand secure groupcommunication have not only brought innovationstothecurrentbusinesspractice, butthey alsoposeabigchallenge to protect the information transmitted over the open network from malicious attack
