Strong earthquakes of great intensity pose a severe threat to human life and property. Earthquake early warning systems are designed to give people in endangered areas valuable seconds to save their lives and property. The basis of an efficient warning system is a communication infrastructure that provides high-speed and reliable communication betw...

Volunteers can be a valuable support for disaster management. Disaster management must be able to coordinate volunteers in order to benefit from their support. Interactive, collaborative, and mobile technologies have the potential to overcome the challenges involved in integrating volunteers into crisis and disaster management. This paper presents...

GeoAR, or location-based augmented reality, can be used as an innovative representation of location-specific information in diverse applications. However, there are hardly any software development kits (SDKs) that can be effectively used by developers, as important functionality and customisation options are generally missing. This article presents...

This paper describes the experiences and challenges with the application of the Fraunhofer FOKUS Knowledge Fusion Toolkit within the context of a large-scale project, the lessons learned and the performed design changes to establish a distributed and application-independent framework to support decision-making in intelligent assistance, early warni...

This paper describes an application-independent Knowledge Fusion Toolkit to support decision-making in intelligent assistance, early warning, and security systems. The toolkit is realized on the basis of an industrial strength Java Enterprise technology, providing a runtime environment for modularized knowledge components, which contain all the app...

Mobile devices are a promising platform for content delivery considering the (i) variety of attached sensors, (ii) widespread availability of wireless networks, (iii) even increasing screen estate and hardware specs. What has been missing so far is the adequate coupling of content to those devices and their users’ actions. This is especially appare...

In many application fields such as disaster management or personal planning, efficient mobile services should capture users' context in order to provide them with the most appropriate information at a given time. Situation-based services aim towards this direction. They go beyond location-based services as they take a user's current situation into...

Großveranstaltungen verursachen ein außergewöhnlich hohes Verkehrsaufkommen in der unmittelbaren Nähe des Veranstaltungsortes sowie im gesamten Stadtbereich. Ziel des Projekts TRANSIT (2005-2006) war es, Veranstaltungsbesuchern – hier Besuchern der FIFA Fussball-Weltmeisterschaft 2006™ in Berlin – mobile, intermodale Verkehrsinformationsdienste zur...

In applications that need meteorological forecast data, for instance for planning purposes (such as construction or environmental applications), each weather service is currently an effort-intensive result of domain-dependent programming. Instead, such applications need weather information platforms that would combine new forecast technologies and...

Großveranstaltungen verursachen ein außergewöhnlich hohes Verkehrsaufkommen in der unmittelbaren Nähe des Veranstaltungsortes - wie zum Beispiel einem Sportstadion sowie im gesamten Stadtbereich. TRANSIT stellt Veranstaltungsbesuchern mobile, verkehrsbezogene, intermodale Dienste zur Verfügung, damit sie auf dem optimalen Weg an einen bestimmten Or...

Demand-orientation is of crucial importance in mobile and pervasive information services in order to ensure the delivery of the right information at the right time and at the right place. In the past years, increasing attention has been devoted to the notion of personalized services that take the situation of the user into account. The trade-off is...

Unterschiedliche Sichten auf einen Anwendungsbereich drücken sich in unterschiedlich strukturierten Modellen aus. Diese Modelle enthalten im allgemeinen unterschiedliche Arten von Informationen über Objekte ihres Anwendungsbereiches. In diesem Beitrag soll ein Konzept zur Modellintegration beschrieben werden, das die Zusammenführung dieser Informat...

Bauwerke werden heute mit umfassender Systematik Bauwerke werden heute mit umfassender Systematik die Brauchbarkeit der Bauwerke werden durch Normung und Prüfung intensiv beeinflußt. Der Computereinsatz ist in diesem Bereich allgemein üblich. Im Gegensatz zu Planungs- und Ausführungsphase eines Bauwerks ist die Betriebsphase wenig systematisiert. D...

In recent years, there has been considerable develop- ment to support personalized services that take the situa- tion of a user into account. One of the major problems in this area is to ensure an optimal information supply and to prevent information overload. Comparing situations pre- dicted by the system with the expectations of a user yields inf...

A considerable part of today's enterprise information flow consists of the exchange of messages between individuals such as e-mail correspondence. With the increasing amount of such messages several problems in information logistics arise that lead to an inefficient and sometimes inconsistent information flow. One major problem is that today's mess...

In order to deliver relevant information at the right time to its mobile users, systems such as event notification systems need to be aware of the users’ context (e. g., time, location, used devices). Many context frameworks have been introduced in the past few years. However, they usually do not consider the no- tion of characteristic features of...

The aim of information logistics is to reduce information overflow by utilizing the paradigm of a demand-oriented information supply. We focus on asynchronous message-based communication processes in collaborative environments. Our main task in this context is the assessment of messages with respect to the situations of the receiver. This work pres...

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 implementa...

Ubiquitous computing, applications that serve users with information in any situation is currently a topic of frequent discussion. In this paper we argue that many of these applications lead to an information overflow rather than providing the user with the appropriate kind of information. We, therefore, introduce an approach that we call informati...

Zur Jahreswende 1999/2000 schlug das Orkantief "Lothar" eine Schneise der Verwüstung durch Frankreich, die Schweiz und Süddeutschland. Obwohl es im Internet schon am Vorabend die ersten Hinweise über das Aufziehen eines schweren Sturms gab, wurden Warnungen über Radio und Fernsehen an die Bevölkerung erst verbreitet als es für Sicherungsmaßnahmen b...

Der vorliegende Bericht dokumentiert das Konzept zum Wissenstransfermodell Scalable Innovation Process (SIP), das innerhalb des Projekts easy.going* ausgearbeitet wurde. Die Zielstellung dieses Modells ist es, insbesondere Kleinen und Mittleren Unternehmen (KMU) einen kostengünstigen Einstieg in eine auf KMU-Problemstellungen zugeschnittene Gemeins...
