1. 1. Improving image quality in multi-channel printing - multilevel halftoning, color separation and graininess characterization

   Författare :Paula Žitinski Elías; Sasan Gooran; Daniel Nyström; Marius Pedersen; Linköpings universitet; []

   Sammanfattning : Color printing is traditionally achieved by separating an input image into four channels (CMYK) and binarizing them using halftoning algorithms, in order to designate the locations of ink droplet placement. Multi-channel printing means a reproduction that employs additional inks other than these four in order to augment the color gamut (scope of reproducible colors) and reduce undesirable ink droplet visibility, so-called graininess.

3. 2. Mitigation of urban storm water runoff through application of computational fluid dynamics

   Författare :Kaj Pettersson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microstructure; infiltration; Green roof; CFD; wind-driven rain; building facade.; lattice Boltzmann;

   Sammanfattning : This thesis covers computational methods for improving the ability of green roofs to mitigate storm water runoff in urban environments. Roofs with living vegetation, known as green roofs, have been used for this purpose however quantification of their ability to slow and stop rainfall runoff has not been undertaken to a large degree.
