Shadows heighten realism and provide important visual cues about the spatial relationships between objects. But integration of robust shadow shadowing techniques in real-time rendering is not an easy task. In this course on how shadows are incorporated in real-time rendering, attendees learn basic shadowing techniques and more advanced techniques that exploit new features of graphics hardware.The

Popular Abstract in Swedish De flesta bakterier lever i harmoni med människan, på huden och på olika slemhinnor framför allt i mag-tarmkanalen. Cellerna på dessa ytorna utgör ett effektivt skydd mot sjukdomsalstrande bakterier. Ibland bryts emellertid försvarsbarriären och bakterierna kan få tillgång till delar av kroppen som normalt är sterila. De är försvarade av fagocyter, ätarceller, som omsluStreptococcus pyogenes causes infections only in humans, from trivial tonsillitis to life-threatening conditions. One of its most important virulence factors is the M-like protein family conferring resistance to phagocytosis to the bacterium. The M-like proteins are surface exposed rod-like molecules attached to the cell wall. Each strain of S. pyogenes expresses unique M-like proteins that bind t

Energy security has become a key priority in EU policy but climate change mitigation commitments live on in parallel. The purpose of this paper is to analyse the extent to which EU climate change mitigation policies and energy security policies are coherent – a relationship that is far from clear cut since both areas are both complex and wide ranging. We use a simple policy-analytical framework fo

To a large extent, the thesis deals with a future solar telescope, the Large Earth-based Solar Telescope (LEST). The dynamical properties of the telescope, in particular its live optics system, have been investigated through implementation of a computer model, which has been used for simulations. The model includes the various parts of the telescope, as well as various image degrading effects. Of

The latest technology and architectural trends have significantly improved the use of a large variety of glass products in construction which, in function of their own characteristics, allow to design and calculate structural glass elements under safety conditions. Both monolithic as well as laminated glass can be used for these proposals. In the case of laminated elements interlayers of polymers

A method is described for identifying simultaneous signals from different transmit antennas in multi-antenna sounders. Multiple orthogonal signals are produced from one pseudorandom code by using it to modulate RF carriers at pre-calculated offset frequencies. Although their frequency spectra are interleaved, the spectral lines from different transmitters are separable by Fourier transform at the
