ASKALON: A Development and Grid Computing Environment for Scientific Workflows

Abstract: Most existing Grid application development environments provide the application developer with a nontransparent Grid Commonly, application developers are explicitly involved in tedious tasks such as selecting software components deployed on specific sites, mapping applications onto the Grid, or selecting appropriate computers for their applications Moreover, many programming interfaces are either implementation-technology-specific (eg, based on Web services [24]) or force the application developer to program at a low-level middleware abstraction (eg, start task, transfer data [22, 153]) While a variety of graphical workflow composition tools are currently being proposed, none of them is based on standard modeling techniques such as Unified Modeling Language (UML)

ESCAPE: an adaptive framework for managing and providing context information in emergency situations

Abstract: Supporting adaptive processes in tackling emergency situations, such as disasters, is a key issue for any emergency management system. In such situations, various teams are deployed in many sites, at the front-end or back-end of the situations, to conduct tasks handling the emergency. Context information is of paramount importance in assisting the adaptation of these tasks. However, there is a lack of middleware supporting the management of context information in emergency situations. This paper presents a novel framework that manages and provides various types of context information required for adapting processes in emergency management systems.

The WORKPAD P2P Service-Oriented Infrastructure for Emergency Management

Abstract: In this paper~ we present the architecture of the research project WORKPAD 1. This project aims at designing and developing an innovative service-oriented software infrastructure J/br supporting collaborative work of human operators in emergency/disaster scenarios. In such scenarios, different teams, belonging to different organizations, need to collaborate with one other; each team member is equipped with handheld devices (PIJAs) and communication technologies, and should carry on specific tasks. In such a case we can consider the whole team as carrying on a process, and the different teams collaborate through the "interleaving " of all the different processes. Each team is supported by some back-end centres, which need to cooperate at an inter-organizational level.
