1. 1. Development of New Methods for Inferring and Evaluating Phylogenetic Trees

   Författare :Tobias Hill; Helgi Schiöth; Robert Fredriksson; Mark Wilkinson; Uppsala universitet; []
   Nyckelord :Pharmacology; Evolution; Phylogeny; SPR; Genetic Algorithm; Tree metrics; Farmakologi;

   Sammanfattning : Inferring phylogeny is a difficult computational problem. Heuristics are necessary to minimize the time spent evaluating non optimal trees. In paper I, we developed an approach for heuristic searching, using a genetic algorithm. Genetic algorithms mimic the natural selections ability to solve complex problems. LÄS MER

3. 2. Fluid Flow Phenomena, Inclusion Characteristics and some Heat Transfer Phenomena during Filling of an Ingot Mmold

   Författare :Robert Eriksson; KTH; []
   Nyckelord :up-hitt teeming; model powder; inclusions; plant trials; thermal diffusivity; fluid flow; physical modeling;

   Sammanfattning : Clean steel production requires a good understanding of theinclusion characteristics at all stages of the steelmakingprocess. So far there exist little information about theformation and evolution of inclusions during the filling ofingot molds. LÄS MER
