The WibQuS project investigates distributed computer and communication support for Total Quality Management in industrial organizations. An interdisciplinary study of this task reveals three aspects of intelligent cooperation required from such a system which we call conceptual, technical, and social integration. We use the repository standard IRDS to characterize these aspects. A solution conc...

An efficient usage of available resources is a substantial requirement for the successful design of networked control systems. Recent results indicate major benefits of event-based control compared to conventional designs, when resources such as communication, energy, and computation, are sparse. This paper considers multiple entities of heterogeneous control systems whose feedback loops are co...

Subsystem codes protect quantum information by encoding it in a tensor factor of a subspace of the physical state space. Subsystem codes generalize all major quantum error protection schemes, and therefore are especially versatile. This paper introduces numerous constructions of subsystem codes. It is shown how one can derive subsystem codes from classical cyclic codes. Methods to trade the dim...

In this paper, we describe a multimedia system architecture consisting of: (1) an information management subsystem, (2) a storage subsystem, and (3) a network subsystem. Whereas the informationmanagement subsystem provides means for identifying the set of multimedia objects that may be pertinent to a client’s query, the storage subsystem ensures that multimedia objects are efficiently stored an...
