Partikelschwarmoptimierung (PSO) ist eine in der Praxis immer wieder sehr erfolgreich eingesetzte Metaheuristik zum Lösen von Black-Box-Optimierungsproblemen und wird speziell im Fall eines kontinuierlichen Suchraums verwendet. Dazu wird das in der Natur häufig auftretende Schwarmverhalten von miteinander kooperierenden Individuen imitiert. Die Dissertation liefert einen Beitrag zum besseren Ve...

The bounding-box of a geometric shape in 2D is the rectangle with the smallest area in a given orientation (usually upright) that complete contains the shape. The best-fit bounding-box is the smallest bounding-box among all the possible orientations for the same shape. In the context of document image analysis, the shapes can be characters (individual components) or paragraphs (component groups...

The aim of the present study was to verify the hypothesis that cavity design does not affect the strength of direct composite restorations as do material properties. Finite element modeling (FEM) and empirical testing were done for two cavity designs: a box shape (cube) and a concave shape (U). Two microhybrid composites were used to prepare the samples with the help of split stainless steel mo...

Evaluating the performance of an agent or group of agents can be, by itself, a very challenging problem. The stochastic nature of the environment plus the stochastic nature of agents’ decisions can result in estimates with intractably large variances. This paper examines the problem of finding low variance estimates of agent performance. In particular, we assume that some agent-environment dyna...

The hallmark of eukaryotic evolution was the development of the nucleus in cells. This compartmentalization requires the nucleocytoplasmic transport of thousands of molecules. The gate into and out of the nucleus is the nuclear pore complex (NPC). One of the molecules that needs to be exported from the nucleus is messenger RNA (mRNA). mRNA associates with proteins in the nucleus forming a messe...
