  1. 6. Algorithms for Costly Global Optimization

    Författare :Nils-Hassan Quttineh; Kenneth Holmström; Hans Bruun Nielsen; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimization; systems theory; Optimeringslära; systemteori; Mathematics Applied Mathematics; Matematik tillämpad matematik;

    Sammanfattning : There exists many applications with so-called costly problems, which means that the objective function you want to maximize or minimize cannot be described using standard functions and expressions. Instead one considers these objective functions as ``black box'' where the parameter values are sent in and a function value is returned. LÄS MER

  3. 7. Approximation of topology optimization problems using sizing optimization problems

    Författare :Anton Evgrafov; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; structural optimization; bilevel programming; approximation; topology optimization; control in coefficients; optimal design; fictitious domain; control in coefficients;

    Sammanfattning : The present work is devoted to approximation techniques for singular extremal problems arising from optimal design problems in structural and fluid mechanics. The thesis consists of an introductory part and four independent papers, which however are united by the common idea of approximation and the related application areas. LÄS MER

  4. 8. A Global Linear Optimization Framework for Adaptive Filtering and Image Registration

    Författare :Gustaf Johansson; Hans Knutsson; Mats Andersson; Klas Nordberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Global Linear Optimization; Linear Optimization; Regularization; Medical Image Registration; Structure Tensor;

    Sammanfattning : Digital medical atlases can contain anatomical information which is valuable for medical doctors in diagnosing and treating illnesses. The increased availability of such atlases has created an interest for computer algorithms which are capable of integrating such atlas information into patient specific dataprocessing. LÄS MER

  5. 9. Global Optimization in Computer Vision: Convexity, Cuts and Approximation Algorithms

    Författare :Carl Olsson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Spectral Relaxation; Normalized Cuts; Continuous Cuts; Segmentation; Generalized Convexity; 3D-Reconstruction; Global Optimization; Multiple View Geometry; Trust Region Subproblem;

    Sammanfattning : Computer vision is today a wide research area including topics like robot vision, image analysis, pattern recognition, medical imaging and geometric reconstruction problems. Over the past decades there has been a rapid development in understanding and modeling different computer vision applications. LÄS MER

  7. 10. Energy systems analysis of Swedish pulp and paper industries from a regional cooperation perspective : Case study modeling and optimization

    Författare :Sofia Klugman; Bahram Moshfegh; Thore Berntsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial energy system; Optimization; District heating; Energy audit; Co-operation; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The industrial sector uses about one third of the energy end-use in the world. Since energy use in many cases highly affects both the local and global environment negatively, it is of common interest to increase energy efficiency within industries. LÄS MER
