The forklift truck enables the identification of pallets, picking them up and automatically putting them down again in another place. The essential innovation of the system is that the pallets do not have to be put at a pre-defined hand over point, but instead are picked up flexibly from varying positions and heights. A further significant innovation can be found in the localization equipment. The 3D ceiling localization system enables navigation in a highly changeable environment.
BibSonomy is a Web 2.0 platform which allows users to store, organize, and share bibliographic data. Users can describe their content using freely chosen keywords – so-called tags.

The SLA4D-Grid Project is designing and realising a Service Level Agreement layer for the Germany’s national Grid infrastructure D-Grid. The Service Level Agreement layer offers individual users, whole D-Grid communities, and the providers of D-Grid resources service usage under given guarantees, quality-of-service requirements and pre-defined business conditions. For this purpose, service level requests and the corresponding offers are linked by binding Service Level Agreements. By means of the SLA layer and with the assistance of other D-Grid services, such as monitoring and accounting, SLAs can be automatically created, negotiated and their observance monitored, so that the D-Grid can be used by academic and industrial users in an economically efficient manner, in accordance with their respective business models.
STELLAR represents the effort of the leading institutions and projects in European Technology-Enhanced Learning (TEL) to unify our diverse community.
This Network of Excellence is motivated by the need for European research on TEL to build upon, synergize and extend the valuable work we have started by significantly building capacity in TEL research within Europe, which is required to allow the European Union to achieve its goals via the Bologna Agreement and the execution of the Lisbon Agenda. The European TEL agenda has been set for the last 4 years by the Kaleidoscope network – with a huge strength in pedagogy and scientific excellence, and the Prolearn network – with a complimentary strength in technical and professional excellence. Integrating this excellence and moving on to the higher strategic formation of policy based in leading research is the key challenge for the next stage.
STELLAR will move beyond the earlier networks by setting a new and critical foresight agenda for Technology Enhanced Learning. The Network will be executed via a series of integration instruments designed to increase the research capacity of European TEL at all levels.
STELLAR’s instruments will act upon the backbone of an interlocking set of 3 Grand Research Challenge actions, themed as Connecting People, Orchestration and Context.

Today broadband Internet access is often regarded as an important and strategic factor for enterprises, private households and also for the medical and the educational sector. Unfortunately, today there is still a digital divide between urban and rural areas regarding a basic broadband Internet access. This digital divide is mainly caused by economic constraints. Especially in rural areas, costs are even more intensive and often cannot be amortized in an acceptable period of time. Within the WiMAX project, a wireless technology based on the IEEE 802.16e standard will be analyzed for its capability to provide an economical infrastructure for the future Internet.
