Material properties can vary through the object, lattice structure and internal voids are used for improving performance. State-of-the-art CAD-tools are not well suited for AM as they are b-rep based: An object is represented by its inner and outer hulls. b-rep representation was developed more than 3 decades...

...train unreliability over time on transport demand within a fixed-effect framework. The train services that we study carry high-value consumer goods and compete heavily with trucks. We find that if the share of substantially delayed trains increases by 10 percentage points, freight volume goes down by...

...resazurin, yeast extract, casitone, and using a low salt concentration, that was optimized for Methanosarcina barkeri, Methanobacterium formicicum, and Methanothrix soehngenii. The aim was to provide a medium for follow-up co-culture studies using specific methanogens and Geobacter spp. dominated biofilm...

...energy conservation, and efficiency with environmental compliance through the inter-disciplinary integration of information and communication technologies (ICT) and power system technologies to facilitate the modernization of grids. The paradigm of smart grid has been brought forward and is being continually...

...activities related to wind integration studies in the US and Europe. Transmission planning for energy resources is different from planning for capacity resources. Those differences are explained, and illustrated with examples from several regions of the US and Europe. Transmission planning for wind is becoming...
