This text on distributed computing and real-time systems includes the topics: multimedia; communications database; fault tolerance; timing analysis; operating systems; software systems and programming environments; and scheduling.
Annotation The 47 regular papers and 25 short papers from the December 1999 conference are divided under the following headings: databases, scheduling, software and systems, communications, formal methods, multimedia and architecture, architecture, fault tolerance, real-time requirements, resource management, and O.S. and design spec. Topics include value-driven multi-class overload management, scheduling periodic task systems to minimize output jitter, formal description of real-time systems using SDL, a Matlab toolbox for real- time and control systems co-design, reliability analysis of real-time controllers with dual-modular temporal redundancy, and real-time synchronization between hard and soft tasks in RT-Linux.

In recent years, tremendous research has been devoted to the design of database systems for real-time applications, called real-time database systems (RTDBS), where transactions are associated with deadlines on their completion times, and some of the data objects in the database are associated with temporal constraints on their validity. Examples of important applications of RTDBS include stock trading systems, navigation systems and computer integrated manufacturing. Different transaction scheduling algorithms and concurrency control protocols have been proposed to satisfy transaction timing data temporal constraints. Other design issues important to the performance of a RTDBS are buffer management, index accesses and I/O scheduling. Real-Time Database Systems: Architecture and Techniques summarizes important research results in this area, and serves as an excellent reference for practitioners, researchers and educators of real-time systems and database systems.
The emergence and widespread use personal computers and network technologies have seen the development of interest in the use of computers to support cooperative work. This volume presents the proceedings of the ninth European conference on Computer Supported Cooperative Work (CSCW). This is a multidisciplinary area that embraces the development of new technologies grounded in actual cooperative practices. These proceedings contain a collection of papers that reflect the variegated research activities in the field. The volume includes papers addressing novel interaction technologies for CSCW systems, new models and architectures for groupware systems, studies of communication and coordination among mobile actors, studies of cooperative work in complex settings, studies of groupware systems in actual use in real-world settings, and theories and techniques to support the development of cooperative applications. The papers present emerging technologies alongside new methods and approaches to the development of this important class of applications. The work in this volume represents the best of the current research and practice within CSCW. The collection of papers presented here will appeal to researchers and practitioners alike, as they combine an understanding of the nature of work with the possibility offered by new technologies.
th This volume gathers together the technical papers presented at the 8 European Conference on Computer Supported Cooperative Work (ECSCW), held in Helsinki Finland. ECSCW is an international forum for multidisciplinary research covering the technical, empirical, and theoretical aspects of collaboration and computer systems. The 20 papers presented here have been selected via a rigorous reviewing process from 110 submissions. Both the number of submissions and the quality of the selected papers are testimony to the diversity and energy of the CSCW community. We trust that you will find the papers interesting and that they will serve to stimulate further quality work within the community. The technical papers are complemented by a wider set of activities at ECSCW 2003, including tutorials, workshops, demonstrations, videos, posters and a doctoral colloquium. Together these provide rich opportunities for discussion, learning and exploration of the more recent and novel issues in the field. This conference could not have taken place without considerable enthusiasm, support and participation, not to mention the hard work of a number of people. In particular, we would like to thank the following: • The authors, representing over 17 countries and 97 institutions, who submitted a paper. So many submissions of such high quality are the basis of a good conference. • The members of the program committee who so diligently reviewed and discussed papers. Their collective decisions result in a good scientific program and their feedback to authors strengthens the work of the community.
This volume contains three keynote papers and 51 technical papers from contributors around the world on topics in the research and development of database systems, such as Data Modelling, Object-Oriented Databases, Active Databases, Data Mining, Heterogeneous Databases, Distributed Databases, Parallel Query Processing, Multi-Media Databases, Transaction Management Systems, Document Databases, Temporal Databases, Deductive Databases, User Interface, and Advanced Database Applications.
