We describe our experience creating a robots community using standard hardware and software – the Windows CE operating system, XScale development boards, and LEGO Mindstorm actuators. We focus on an open and extendable distributed robotics system, which in contrast to most existing proprietary robotics systems, supports cost-effective integration and(More)
Asset tracking offers high potential to improve efficiency of warehouse management. Typically the tracking is done employing RFID technology. As yet however, most goods are not prepared with RFID and it would require investment in costly hardware, infrastructure, and process adaptations. WLAN-based asset tracking is getting ready as a cost-effective(More)
Phosphatidylethanolamine (PE) and phosphatidylglycerol (PG) were co-isolated with the low molecular weight rat surfactant-associated protein C (SP-C) of Mr approximately equal to 6,000. The contribution of these phospholipids to the incorporation of 3H-labeled phosphatidylcholine (PC) liposomes into rat alveolar type II cells stimulated by SP-C was(More)
Web Services appear promising to facilitate interoperability and enable Dynamic Value Webs – the on-demand aggregation of services even across enterprise boundaries. However, past experiences have shown interoperability limitations in practice mainly due to information asymmetries on the Web Services markets. This Paper describes a service-oriented(More)
Zusammenfassung: Positionsbestimmung auf Basis der Commodity-Kommunikationstechnologien WLAN, Bluetooth und RFID erfreut sich zunehmender Beliebtheit, verfügbare Systeme erreichen bereits in vielen Fällen passable Genauigkeiten. Forschungsbedarf besteht aber noch im geeigneten Umgang mit Positionierungsambiguitäten, Umgebungsdynamik und Peer-to-Peer-Ortung.(More)
Data sharing in a large scale and for high volatility tolerance requires peer-to-peer solutions where traditional multiprocessor shared memory systems are not applicable. Efficiency of those P2P shared memory systems depends, in particular, on scale, dynamics, and concurrent write accesses. We have developed a P2P shared memory solution, DAEDALUS, based on(More)
