The atmospheric wind and temperature can be estimated through the traveltimes of infrasound between pairs of receivers. The traveltimes can be obtained by infrasonic interferometry. In this study, the theory of infrasonic interferometry is verified and applied to modeled stratospherically refracted waves. Synthetic barograms are generated using a raytracing model and taking into account atmosph...

today, the issue concerning the conferment of the whole or a part of the material rights belonging to the author and the related contracts is of special importance, to the extent that in some legal systems, such as the french, various specific contracts, like the publication contract, special provisions and regulations have been devised for it. whereas, no special rules concerning the above-men...

For the update summaries task of the Text Analysis Conference 2008 we have implemented a novel summarization technique based on query expansion with encyclopedic knowledge and activation spreading in a large document graph. We have also experimented with sentence compression for building the summaries. The results are average – ranked 27 out of 58 for responsiveness in manual evaluation – but w...

We propose a framework for deterministic simulation of user behavior that allows to analyze the cost-gain-based performance on single result lists or whole search sessions. The ideal user representing optimal behavior (i.e., most gain with lowest effort) is contrasted with more “average” users that employ the spreading activation model from cognitive theory. On TREC Session Track data, the idea...

The ultimate goal of this work was to develop a biocompatible and biomimetic in situ crosslinkable hydrogel scaffold with an instructive capacity for bone regenerative treatment. To this end, synthetic hydrogels were functionalized with two key components of the extracellular matrix of native bone tissue, i.e. the three-amino acid peptide sequence RGD (which is the principal integrin-binding do...
