  1. 1. Cost Optimization of Aircraft Structures

    University dissertation from Stockholm : KTH

    Author : Markus Kaufmann; KTH.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aircraft structures; optimization; cost estimation; manufacturing cost; direct operating cost; multiobjective optimization; multidisciplinary optimization; composites; airframe design; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik 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

    University dissertation from Växjö : Växjö University Press

    Author : Morgan Ericsson; Växjö universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; software composition; software reuse; optimization; high-performance computing; Datavetenskap; Data- och informationsvetenskap; Computer and Information Sciences Computer Science;

    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

  4. 4. Ride Comfort Optimization of Buses

    University dissertation from Chalmers University of Technology

    Author : Peter Eriksson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Samhällsbyggnadsteknik och arkitektur; Civil engineering and architecture; Teknisk mekanik; Engineering mechanics; bus; ride comfort; optimization; road irregularities; structural vibrations; FEM; MBS; global optimization; sensitivity analysis; roll control system;

    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. Multicriteria optimization for managing tradeoffs in radiation therapy treatment planning

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Rasmus Bokrantz; KTH.; [2013]
    Keywords : 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
