As the business environment has become more and more turbulent over the past decade, information technology has begun to run into the danger of becoming an impediment rather than a motor of progress. In order to deal with the need for rapid, continuous change, computer science is challenged to develop novel interrelated information and communication technologies, and to align them with the social needs of co-operating user groups, as well as the management requirements of formal organisations. Workflow systems are among the most advertised technologies addressing this trend, but they mean different things to different people. computer scientists understand workflows as a way to extract control from application programs, thus making them more flexible. Bureaucratic organisations (and most commercial products) perceive them as supporting a linear or branching flow of documents from one workplace to another - the next try after the failure cf office automation. This book takes another perspective, that of the modem customer-driven and groupwork-oriented process organisation. Extending the language-action perspective from the CSCW field, its customer-oriented view of workflows enables novel kinds of business process analysis, and leads to interesting new combinations of information and co-operation technologies. Schal's empirical studies show some of the pitfalls resulting from a naive use of these technologies, and exemplify ways to get around these pitfalls.

This lecture presents a first compendium of established and emerging standards in pervasive computing systems. The lecture explains the role of each of the covered standards and explains the relationship and interplay among them. Hopefully, the lecture will help piece together the various standards into a sensible and clear landscape. The lecture is a digest, reorganization, and a compilation of several short articles that have been published in the “Standards and Emerging Technologies” department of the IEEE Pervasive Computing magazine. The articles have been edited and shortened or expanded to provide the necessary focus and uniform coverage depth. There are more standards and common practices in pervasive systems than the lecture could cover. However, systems perspective and programmability of pervasive spaces, which are the main foci of the lecture, set the scope and determined which standards should be included. The lecture explains what it means to program a pervasive space andintroduces the new requirements brought about by pervasive computing. Among the standards the lecture covers are sensors and device standards, service-oriented device standards, service discovery and delivery standards, service gateway standards, and standards for universal interactions with pervasive spaces. In addition, the emerging sensor platform and domestic robots technologies are covered and their essential new roles explained. The lecture also briefly covers a set of standards that represents an ecosystem for the emerging pervasive healthcare industry. Audiences who may benefit from this lecture include (1) academic and industrial researchers working on sensor-based, pervasive, or ubiquitous computing R&D; (2) system integrator consultants and firms, especially those concerned with integrating sensors, actuators, and devices to their enterprise and business systems; (3) device, smart chips, and sensor manufacturers; (4) government agencies; (5) the healthcare IT and pervasive he

The first edition having been sold out, gives me a welcome opportunity to augment this volume by some recent applications of speech research. A new chapter, by Holger Quast, treats speech dialogue systems and natural lan guage processing. Dictation programs for word processors, voice dialing for mobile phones, and dialogue systems for air travel reservations, automated banking, and translation over the telephone are at the forefront of human-machine inter faces. Spoken language dialogue systems are also invaluable for the physically handicapped. For researchers new to the field, the new chapter (pp. 67-106) provides an overview of fundamental linguistic concepts from phonetics, morphology, syntax, semantics and pragmatics, gramm ars and knowedge representation. Symbolic methodology, such as Norman Chomsky's traditional hierarchy of formal languages is layed out as are statistical approaches to analyze text. Proven tools of language processing are covered in detail, including finite state automata, Zipf's law, trees annd parsers. The second part of the new chapter introduces the building blocks of state-of-the-art dialogue systems.

Dieses Lehrbuch behandelt verständlich, umfassend und modern die Theorie der Berechenbarkeit, ein klassisches Gebiet der Mathematischen Logik, das als Grundlagengebiet auch für die Informatik von höchster Bedeutung ist. Lebendig und didaktisch klar wird das Studium der berechenbaren Funktionen auf dem Programmbegriff aufgebaut. Dabei sind die Induktion als Beweisprinzip und die Rekursion als Konstruktionsprinzip die beiden grundlegenden Werkzeuge für den Umgang mit Zahlen und Funktionen. Obwohl über eine gewisse Vertrautheit mit der mathematischen Argumentationsweise hinaus keine inhaltlichen Kenntnisse aus der Mathematik oder der Informatik vorausgesetzt werden, findet auch der Kenner eine durch viele neuartige Details angereicherte und an neuesten Ergebnissen orientierte Darstellung.

The intricate relationship between information technologies, community, and social memory is critical to a fuller understanding of the evolution of our societies. Telecommunications and information technologies modify the process of accessing and storing data and knowledge, and consequently they also modify our relationship with both social and historical m- ory. Our various virtual communities continue to expand on a planetary scale, and hence the neologism “Global Village”, while concurrently, their physical counterparts are progressively being contained within speci?c contexts and places, often referred to as a process of “localization”. And then, there is the unpredictable evolution of today’s communication s- tems, an evolution that has been de?ned by Albert Einstein as the third bomb of the 20th century, after the atomic bomb and the demographic bomb. Therefore, as communication systems continue to develop, we face new scenarioswithimpreciseboundaries,thatleadtoendlessnewopportunities for establishing the relationship between social memory, community, and information systems. How can the knowledge process dynamic, together with the storing and transmitting of information, sounds, and images through digital devices, affect the communal memory and the way we both conceive of and create communities? We have at least three emerging paradigms that help us to understand the phenomena concerning the evolution of social memory linked with the recent diffusion of communication technologies.
