  1. 1. Cost Optimization of Aircraft Structures

    Author : Markus Kaufmann; Dan Zenkert; Malin Åkermo; Per Wennhage; Erik Lund; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aircraft structures; optimization; cost estimation; manufacturing cost; direct operating cost; multiobjective optimization; multidisciplinary optimization; composites; airframe design; Vehicle engineering; Farkostteknik;

    Abstract : Composite structures can lower the weight of an airliner significantly. Due to the higher process complexity and the high material cost, however, the low weight often comes with a significant increase in production cost. The application of cost-effective design strategies is one mean to meet this challenge. READ MORE

  2. 2. Composition and Optimization

    Author : Morgan Ericsson; Uwe Assmann; Växjö universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; software composition; software reuse; optimization; high-performance computing; Datavetenskap; Computer and Information Sciences Computer Science; Data- och informationsvetenskap;

    Abstract : A recent trend in software engineering is to delay design decisions. One motivation is that requirements or properties of the application and environment are not known until later in the design and development process. This continues to hold for design decisions in a high-performance context where e.g. READ MORE

  3. 3. Multicriteria optimization for managing tradeoffs in radiation therapy treatment planning

    Author : Rasmus Bokrantz; Anders Forsgren; Karl-Heinz Küfer; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Optimization; multicriteria optimization; robust optimization; Pareto optimality; Pareto surface approximation; Pareto surface navigation; intensity-modulated radiation therapy; volumetric-modulated arc therapy; intensity-modulated proton therapy; Optimering; flermålsoptimering; robust optimering; Paretooptimalitet; Paretofrontsapproximation; Paretofrontsnavigering; intensitetsmodulerad strålterapi; rotationsterapi; intensitetsmodulerad protonterapi;

    Abstract : Treatment planning for radiation therapy inherently involves tradeoffs, such as between tumor control and normal tissue sparing, between time-efficiency and dose quality, and between nominal plan quality and robustness. The purpose of this thesis is to develop methods that can facilitate decision making related to such tradeoffs. READ MORE

  4. 4. Ride Comfort Optimization of Buses

    Author : Peter Eriksson; Chalmers University of Technology; []
    Keywords : structural vibrations; FEM; global optimization; ride comfort; roll control system; MBS; optimization; bus; road irregularities; sensitivity analysis;

    Abstract : As the design of buses is constantly improving, passengers are becoming more fastidious and the demand for a more comfortable travelling environment is constantly increasing. The main objective of this thesis is to contribute to the understanding of how the design of buses affects the ride comfort characteristics. READ MORE

  5. 5. Combinatorial Optimization : Three Applications

    Author : Efraim Laksman; Blekinge Tekniska Högskola; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Combinatorial optimization is a diverse area of mathematics. It concerns optimization on feasible regions defined by discrete sets, graphs, hypergraphs, matroids, etc. . . READ MORE
