This paper pre sents and discusses a new approach to collect, organize and explore multiple digital videos on a spatial basis. We present a methodology based on direct video frame indexation to the real space represented in the video images. This approach facilitates the exploration of space through multiple videos. An illustrative application of this technology for multimedia spatial informati...

In an issue of the Wireless World magazine, back in 1945, A. C. Clarke on a letter to the editor wrote " However, I would like to close by mentioning a possibility of the remote future-perhaps half a century ahead... Three repeater stations, twelve degrees apart in the correct orbit, could give television and microwave coverage to the entire planet. " These words envisioned, before the space er...

During development, processor architectures can be tuned and configured by many different parameters. For benchmarking, automatic design space explorations (DSEs) with heuristic algorithms are a helpful approach to find the best settings for these parameters according to multiple objectives, e.g. performance, energy consumption, or real-time constraints. But if the setup is slightly changed and...

The COPS (Classification Of Protein Structures) web server provides access to the complete repertoire of known protein structures and protein structural domains. The COPS classification encodes pairwise structural similarities as quantified metric relationships. The resulting metrical structure is mapped to a hierarchical tree, which is largely equivalent to the structure of a file browser. Exp...

In order to establish an objective framework for studying galaxy morphology, we have developed a quantitative two-parameter description of galactic structure that maps closely on to Hubble’s original tuning fork. Any galaxy can be placed in this “Hubble space,” where the x-coordinate measures position along the early-to-late sequence, while the y-coordinate measures in a quantitative way the de...

representation of it in terms of its volumetric properties tomatch this token to our mental inventory of such types. Although recent developments have challenged the role of the D model within a modular theory of vision, there can be little doubt that at some conceptual level such an object-centred frame of reference exists. This is further demonstrated by work on visual imagery, which seems t...

Binary population synthesis calculations and associated predictions, especially event rates, are known to depend on a significant number of input model parameters with different degrees of sensitivity. At the same time, for systems with relatively low formation rates, such simulations are heavily computationally demanding and therefore the needed explorations of the high-dimensional parameter s...
