We apply social network analysis methods to describe the evolution of the innovator network of Jena, Germany in the period from 1995 to 2001. We find this evolution to be directed towards an increasing focus on core competencies of the local innovation system. Further we analyze the network resulting from R&D cooperations and explain by means of network(More)
This contribution reports on a case study in the application of tool-based methods for a systematic analysis of hybrid systems. In particular, the study is focussed on continuous processes controlled by logic controllers, as this class of hybrid systems is widespread among process industry plants. To achieve comparable results, all methods and tools under(More)
Strong interaction of innovative actors within a local network is commonly said to increase the region-specific knowledge-stock, leading to a comparative advantage. However, it might also lead to a lock-in situation, if local trajectories are directed towards inferior solutions. Accordingly, it is argued that successful clusters are characterised by the(More)
In this paper, we present a markerless 3D motion capture system based on a volume reconstruction technique of non rigid bodies. It depicts a new approach for pose estimation in order to fit an articulated body model into the captured real-time information. We aim at analyzing athlete's movements in real-time within a 3D interactive graphics system. The(More)
The rapid development of geo-referenced information changed the way on how we access and interlink data. Smartphones as enabling devices for information access are main driving factor. Thus, the hash key to information is the actual position registered via camera and sensory of the mobile device. A rising technology in this context is Augmented Reality (AR)(More)
Skeleton extraction and visualization of 3D reconstructed target objects from multiple views continues to be a major challenge in terms of providing intuitive and uncluttered images that allow the users to understand their data. This paper presents a three-dimensional skeleton extraction technique of deformable objects based on a normalized gradient vector(More)
