Traditional recommender systems as they are mostly used in today’s recommendation applications (e.g. the SMART Recommendations Engine of Fraunhofer FOKUS) primarily concentrate on recommending items to users. However, thinking of many modern (mobile) applications, contextual and semantic information may provide a significant preciseness to the recommendation process. That’s why, Fraunhofer FOKU...

We present an approximation for the numerical calculation ofČerenkov radio pulses in the Fraunhofer limit from very high energy showers in dense media. We compare it to full Montecarlo simulations in ice studying its range of applicability and show how it can be extended with a simple algorithm. The approximation reproduces well the angular distribution of the pulse around thě Cerenkov directio...

A publication by Fraunhofer IESE Fraunhofer IESE is an institute of the Fraunhofer Gesellschaft. The institute transfers innovative software development techniques, methods and tools into industrial practice, assists companies in building software competencies customized to their needs, and helps them to establish a competetive market position. Abstract Capturing a process as it is being execut...

The Fraunhofer Institute for Experimental Software Engineering (IESE) recognized reverse engineering as an essential competence and thus has been active in the field since 1996, which is right from its beginning. The role of reverse engineering, however, within the institute changed over time. Since Fraunhofer IESE is an applied research institute its competencies are tailored to the market to ...

Fulgide is well-known as a thermally irreversible organic photochromic compound [1,2]. It is one of the important materials in the field of optical signal processing and optical storage. Focusing on the holographic storage applications of 3indoly-benzylfulgimide/PMMA film, in this chapter include the following themes. In section 2, first the Fulgide, photochroism and photo-induced anisotropy ar...

The customary defocussed and Foucault modes of Lorentz microscopyare usually described in terms of geometric optics. Wohlleben has shown that geometric optics has a restricted range of validity, however; a more fundamental approach is provided by wave optics. The defocussed and Foucault modes may be discussed in terms of wave optics, and for the defocussed mode it can be shown explicitly that t...

INTRODUCTION In laser-scanning measurement of cylindrical objects extremely complex interfering signals occur. They are due to superimposition of reflected, unobstructed and scattered light. The proportions between these components vary in time and also the total intensity distribution changes. The considerations applying Fraunhofer theory are static and fragmentary, and may be concluded that t...
