Efficient and effective knowledge management plays an increasingly important role in knowledge-intensive organizations. In such organizations knowledge workers require a certain degree of freedom in structuring their own tasks [3]. This essential freedom often conflicts with the organization's need of standardization, control and transparency [5]. The(More)
Efficient and effective knowledge management plays an increasingly important role in knowledge intensive organizations. The research project DYONIPOS focuses on detecting the knowledge needs of knowledge workers and automatically providing this required knowledge just in time. The prototype DYONIPOS generates new knowledge out of artefacts, while avoiding(More)
We demonstrate a scalable architecture for a high-power, high-brightness, solid-state laser based on coherent combinations of master oscillator power amplifier chains. A common master oscillator injects a sequence of multikilowatt Nd:YAG zigzag slab amplifiers. Adaptive optics correct the wavefront of each amplified beamlet. The beamlets are tiled side by(More)
The success of knowledge-intensive organizations depends significantly on the degree of knowledge availability, knowledge transparency, knowledge structuring, and knowledge up-to-dateness. The research project DYONIPOS (DYnamic Ontology based Integrated Process OptimiSation) meets these challenges: DYONIPOS sets up a context sensitive, intelligent and agile(More)
That e-Government can be innovative, adequate implementation structures must be developed. First what is needed and what should be implemented must be defined respectively. If this is clear, who is responsible for the implementation and who is affected by the innovation must be defined respectively. In this paper we will present the DYONIPOS Innovation(More)
We demonstrate a simplified approach toward active polarization control in coherently combined laser architectures. By leveraging optical phase dithers applied by a phase controller, polarization error signals are generated for an entire laser array from a single beam sample of the combined output, enabling closed-loop polarization locking of(More)
Efficient and effective knowledge management plays an increasingly important role in knowledge intensive organizations. That's because on the one hand knowledge workers need more and more knowledge to fulfil their daily work and on the other hand because the ad hoc part of a process increases. In addition the knowledge acquisition for the knowledge workers(More)
We demonstrate a method for single-detector coherent sensing and automated coalignment of group delays in a coherently combined laser array, enabling robust coherent combining of broadband sources despite initial path mismatches exceeding the laser coherence length. The method is based on Fourier-domain filtering of the coherently combined laser beam to(More)
