Context-awareness is one of the drivers of the ubiquitous computing paradigm. Well-designed context modeling and context retrieval approaches are key p- requisites in any context-aware system. Location is one of the primary aspects of all major context models - together with time, identity and activity. From the technical side, sensing, fusing and distributing location and other context information is as important as providing context-awareness to applications and services in pervasive systems. Thematerialsummarizedinthisvolumewasselectedforthe1stInternational Workshop on Location- and Context-Awareness (LoCA 2005) held in coope- tion with the 3rd International Conference on Pervasive Computing 2005. The workshop was organized by the Institute of Communications and Navigation of the German Aerospace Center (DLR) in Oberpfa?enhofen, and the Mobile and Distributed Systems Group of the University of Munich. During the workshop, novel positioning algorithms and location sensing te- niques were discussed, comprising not only enhancements of singular systems, like positioning in GSM or WLAN, but also hybrid technologies, such as the integration of global satellite systems with inertial positioning. Furthermore, - provements in sensor technology, as well as the integration and fusion of sensors, were addressed both on a theoretical and on an implementation level. Personal and con?dential data, such as location data of users, have p- found implications for personal information privacy. Thus privacy protection, privacy-oriented location-aware systems, and how privacy a?ects the feasibility and usefulness of systems were also addressed in the workshop.

USM 2000 is the third event in a series of international IFIP/GI conferences on Trends in Distributed Systems. Following the venues in Aachen, Germany (1996) and Hamburg, Germany (1998), this event in Munich considers the trend towards a Universal Service Market - USM 2000. The trend towards a universal service market has many origins, e.g., the integration of telecom and data communications, the deregulation e?orts with respect to telco markets, the globalization of information, the virtualization of companies, the requirement of a short time-to-market, the advances in network technologies, the increasing acceptance of e-commerce, and the increase in - bility. This leads to new business-to-business (B2B) and business-to-customer (B2C) environments that o?er both challenges and opportunities to enterprises and end-users. There is the need for ubiquitous services, trading, brokering and information management, for service market and business models, and for ?e- ble infrastructures for dynamic collaboration. Researchers, service vendors, and users must cooperate to set up the app- priate requirements for a universal service market and to ?nd solutions with respect to supporting platforms, middleware, distributed applications, and m- agement. The basis for these solution is a common understanding of means for de?ning, creating, implementing, and deploying the service market. Then, s- vice market makers, service aggregators, service auctioneers, ISP, ASP, BPO, and customers can freely interact in a dynamic, open, and universal market place.

Mobile Apps - Programme, die auf Smartphones ausgefuhrt werden - sind derzeit fast nur bei Konsumenten erfolgreich. Ein echtes App-Konzept fur den Business-Markt fehlt nach wie vor. Die Autoren zeigen in dem Band den Weg zu intelligenten Business-Apps fur mobile Geschaftsprozesse, mit deren Hilfe Kunden zeitnah und individuell informiert werden koennen. Die Autoren betrachten Fragen der Anwendung, der Technologie und des Marktes und berucksichtigen auch Cloud-Loesungen.

This book constitutes the refereed proceedings of the International Workshop on Trends in Distributed Systems, TreDS '96, held in Aachen, Germany, in October 1996.
The 21 revised full papers presented were carefully selected from a total of 51 submissions; also included is an invited paper by Sape Mullender and Paul Sijben on quality of service in distributed multimedia systems. Beyond the topic of the CORBA architecture and implementations, the book addresses interoperability issues, formal methods, multimedia communication services, distributed object systems, coordination protocols, reuse, workflow management, etc.

This book constitutes the refereed proceedings of the First International Workshop on Quantum Technology and Optimization Problems, QTOP 2019, held in Munich, Germany, in March 2019.The 18 full papers presented together with 1 keynote paper in this volume were carefully reviewed and selected from 21 submissions. The papers are grouped in the following topical sections: analysis of optimization problems; quantum gate algorithms; applications of quantum annealing; and foundations and quantum technologies.

DCOM, Java-RMI und CORBA sind aktuelle Entwicklungen zur Realisierung rechnerubergreifender verteilter Systeme. Das vorliegende Buch behandelt grundlegende Architekturen und Dienste sowie allgemeine Probleme, die beim Einsatz solcher Verteilungsplattformen entstehen. Am Beispiel von CORBA werden Moglichkeiten der Datenubertragung und des Managements untersucht. Verschiedene Ansatze zur Objektreplikation und dem zugehorigen Load Balancing werden vorgestellt, und es wird auf eine Moglichkeit der Objektmigration eingegangen. Das Verhalten zahlreicher untersuchter Szenarien ist graphisch dargestellt. Verfahren zur Systemanalyse runden das Werk ab.
