23rd International Conference on Distributed Computing systems Workshops

In this paper, we introduce the information logistics concept and demonstrate its relevance for the field of wearable computing. Information logistics is an innovative technology based on the idea that the right information gets to the recipient, e.g. journalist at the right time. The objective is a need- and user-oriented information supply according to just-in-time principles. The Smart-Wear project is a first step towards a personalized, wearable information broker based on the information logistics concept. In this paper, we want to illustrate the complexity of such a project aiming to deliver "information skin-deep". We therefore present the underlying idea as well as the system architecture. We furthermore summarize the experiences and results of the customer study as user acceptance proves to be one of the major tasks of wearable computing due the impact such technologies have on the users.

Guided support for collaborative modeling, enactment and simulation of software development processes

Software Process: Improvement and Practice 2004年第2期9卷

作者： Alejandro Fernández Badie Garzaldeen Ines Grützner Jürgen Münch Laboratorio de Investigación y Formación en Informática Avanzada Facultad de Informática Universidad Nacional de La Plata Argentina Fraunhofer Institute for Integrated Publication and Information Systems (IPSI) in Darmstadt Germany Fraunhofer Institute for Experimental Software Engineering (IESE) in Kaiserslautern Germany

Recently, the awareness of the importance of distributed software development has been growing in the software engineering community. Economic constraints, more and more outsourcing of development activities, and the increasing geographical distribution of companies come along with challenges of how to organize distributed development. In this article, we reason that a common process understanding is mandatory for successful distributed development. Integrated process planning, guidance and enactment are seen as enabling technologies for achieving a unique process view. We present an overview of the software process modeling environment SPEARMINT and the XCHIPS system for web-based process support. SPEARMINT offers extensive capabilities for multi-view modeling and analysis of software development processes. XCHIPS provides capabilities for distributed modeling and offers enactment and simulation functionalities. This article describes the integration of both approaches. The resulting environment provides planners and developers with collaborative planning and enactment support and advanced process guidance via electronic process guides (EPGs). Additionally, experience with the integrated environment is described. We describe, in particular, the usage of this integrated environment in the context of a case study for the development of a learning system. Finally, an overview of related work is given and future research directions are sketched. Copyright © 2004 John Wiley & Sons, Ltd.

Summary form only given. This paper outlines the primary goal of SatNEx which is to achieve long-lasting integration of the European research in satellite communications and to develop a common base of knowledge. Networks of excellence have been introduced as a new instrument within the 6/sup th/ IST framework program, and SatNEx is one of the first consortia to implement the new ideas and to overcome the fragmentation of European research. Through co-operation of outstanding universities and research organizations with excellent expertise in satellite communications, SatNEx will build a European virtual centre of excellence in satellite communications and contribute to the realization of the European Research Area (ERA) SatNEx will include an advisory board incorporating representatives of the European space industry, satellite service providers, and standardization and regulation organizations. SatNEx will collaborate with these players and put together a critical mass of resources and expertise needed for making Europe a world force in the field of satellite communications.

Euromicro Conference on Parallel, Distributed and Network-Based Processing

作者： A. Billig L. Nentwig Fraunhofer-Institute for Software Engineering and Systems Engineering ISST Berlin Germany

Global competition and short innovation cycles in information technology (IT) and multi-media industries (MM) lead to rapidly changing requirements with respect to education and qualification of human resources. Traditional vocational training and education offerings are no longer sufficient in this situation and have to be supplemented with short-term, need-oriented and work-process oriented offers. In *** all actors in the field of media and IT-competence have been considered as community of interest, self-regulating the evolution of qualification offers based on current developments in the market and employment situation. Interaction, communication and self-regulation within this community is supported by an Internet-based Web-Portal, providing evolution mechanisms and matchmaking between suppliers and seekers of jobs and qualification measures. This paper introduces the basic organizational and sociological aspects of ***, outlines the main concepts of the Web-Portal (***) and implementation, and summarizes the lessons learned.

EUROMICRO Conference

作者： Jaksch Pfennigschmidt Sandkuhl Thiel Fraunhofer Institute for Software Engineering and Systems Engineering Berlin Germany School of Engineering Jönköping University Jonkoping Sweden

The field of information logistics aims at developing concepts, technologies and applications for need-oriented information supply. Information-on-demand services are a typical application area for information logistics, as they have to fulfill user needs with respect to content, location, time and quality. The application context is the implementation of the weather-information-on-demand service WIND, providing warnings about hazardous weather conditions to end customers. The major technical aspects presented are (1) an information logistical framework consisting of a set of configurable and adaptive software components and (2) a robust and scalable event-reaction mechanism as part of the framework. Experiences from the WIND project include aspects of system design, development process and operations.

American Control Conference (ACC)

作者： E. Arnold O. Sawodny A. Hildebrandt K. Schneider Fraunhofer Application Center Systems Technology Ehrenberg Germany Institute of Automation and System Engineering Department of Control Engineering Technische Universität Illmenau Germany

For the operation of boom cranes a significant high level of experience is needed to achieve a large amount of handled containers. Therefore, automation systems with anti-sway abilities for boom cranes were developed to increase the handling rate especially for inexperienced crane operators. In the paper, an optimal control approach is presented as an alternative to feedback control systems. After deriving the nonlinear dynamic model, the anti-sway problem is formulated as a nonlinear constrained optimal control problem. The numerical solution method for this optimal control problem is presented. The results are illustrated at measurements for the harbour mobile crane LIEBHERR LHM400.
