Book Description
Addressing important extensions of the relational database model, including deductive, temporal, and object-oriented databases, this book provides an overview of database modeling with the Entity-Relationship (ER) model and the relational model. The book focuses on the primary achievements in relational database theory, including query languages, integrity constraints, database design, computable queries, and concurrency control. This reference will shed light on the ideas underlying relational database systems and the problems that confront database designers and researchers.

Book Description
This volume contains the proceedings of the 4th International Workshop on Distributed Algorithms, held near Bari, Italy, September 24-26, 1990. The workshop was a forum for researchers, students and other interested persons to discuss recent results and trends in the design and analysis of distributed algorithms for communication networks and decentralized systems. The volume includes all 28 papers presented at the workshop, covering current research in such aspects of distributed algorithm design as distributed combinatorial algorithms, distributed algorithms on graphs, distributed algorithms for new types of decentralized systems, distributed data structures, synchronization and load-balancing, distributed algorithms for control and communication, design and verification of network protocols, routing algorithms, fail-safe and fault-tolerant distributed algorithms, distributed database techniques, algorithms for transaction management and replica control, and other related topics.

Book Description
Peter Sagal, the host of NPR’s Wait Wait...Don’t Tell Me! and a popular columnist for Runner’s World, shares “commentary and reflection about running with a deeply felt personal story, this book is winning, smart, honest, and affecting. Whether you are a runner or not, it will move you” (Susan Orlean). On the verge of turning forty, Peter Sagal—brainiac Harvard grad, short bald Jew with a disposition towards heft, and a sedentary star of public radio—started running seriously. And much to his own surprise, he kept going, faster and further, running fourteen marathons and logging tens of thousands of miles on roads, sidewalks, paths, and trails all over the United States and the world, including the 2013 Boston Marathon, where he crossed the finish line moments before the bombings. In The Incomplete Book of Running, Sagal reflects on the trails, tracks, and routes he’s traveled, from the humorous absurdity of running charity races in his underwear—in St. Louis, in February—or attempting to “quiet his colon” on runs around his neighborhood—to the experience of running as a guide to visually impaired runners, and the triumphant post-bombing running of the Boston Marathon in 2014. With humor and humanity, Sagal also writes about the emotional experience of running, body image, the similarities between endurance sports and sadomasochism, the legacy of running as passed down from parent to child, and the odd but extraordinary bonds created between strangers and friends. The result is “a brilliant book about running…What Peter runs toward is strength, understanding, endurance, acceptance, faith, hope, and charity” (P.J. O’Rourke).

Book Description
2010 was the first time that the International Conference on Software Process was held autonomously and not co-located with a larger conference. This was a special challenge and we are glad that the conference gained a lot of attention, a significant number of contributions and many highly interested participants from industry and academia. This volume contains the papers presented at ICSP 2010 held in Paderborn, G- many, during July 8-9, 2010. ICSP 2010 was the fourth conference of the ICSP series. The conference provided a forum for researchers and industrial practitioners to - change new research results, experiences, and findings in the area of software and system process modeling and management. The increasing distribution of development activities, new development paradigms such as cloud computing, new classes of systems such as cyber-physical systems, and short technology cycles are currently driving forces for the software domain. They require appropriate answers with respect to process models and management, suitable modeling concepts, and an understanding of the effects of the processes in specific environments and domains. Many papers in the proceedings address these issues.

Book Description
The purpose of our research is to enhance the efficiency of AI problem solvers by automating representation changes. We have developed a system that improves the description of input problems and selects an appropriate search algorithm for each given problem. Motivation. Researchers have accumulated much evidence on the impor tance of appropriate representations for the efficiency of AI systems. The same problem may be easy or difficult, depending on the way we describe it and on the search algorithm we use. Previous work on the automatic im provement of problem descriptions has mostly been limited to the design of individual learning algorithms. The user has traditionally been responsible for the choice of algorithms appropriate for a given problem. We present a system that integrates multiple description-changing and problem-solving algorithms. The purpose of the reported work is to formalize the concept of representation and to confirm the following hypothesis: An effective representation-changing system can be built from three parts: • a library of problem-solving algorithms; • a library of algorithms that improve problem descriptions; • a control module that selects algorithms for each given problem.
