  1. 16. Some aspects of optimal switching and pricing Bermudan options

    Författare :Ali Hamdi; Boualem Djehiche; Henrik Hult; Luis Alvarez; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis consists of four papers that are all related to the Snell envelope. In the first paper, the Snell envelope is used as a formulation of a two-modes optimal switching problem. The obstacles are interconnected, take both profit and cost yields into account, and switching is based on both sides of the balance sheet. LÄS MER

  3. 17. Automotive Sensor Fusion for Situation Awareness

    Författare :Christian Lundquist; Fredrik Gustafsson; Thomas Schön; Jonas Sjöberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systems engineering; Systemteknik;

    Sammanfattning : The use of radar and camera for situation awareness is gaining popularity in automotivesafety applications. In this thesis situation awareness consists of accurate estimates of theego vehicle’s motion, the position of the other vehicles and the road geometry. LÄS MER

  4. 18. Thermal Fatigue Life Prediction of Solder Joints in Avionics by Surrogate Modeling : A Contribution to Physics of Failure in Reliability Prediction

    Författare :Jonas Arwidson; Peter Leisner; Kouchi Zhang; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Manufacturers of aerospace, defense, and high performance (ADHP) equipment are currently facing multiple challenges related to the reliability of electronic systems. The continuing reduction in size of electronic components combined with increasing clock frequencies and greater functionality, results in increased power density. LÄS MER

  5. 19. Robust intersection of hexahedral meshes and triangle meshes with applications in finite volume methods

    Författare :Frida Svelander; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; triangle-hex intersection; overlapping triangles; degenerate mesh; volume fraction; area fraction; cut cell; conjugated heat transfer.; triangle-hex intersection;

    Sammanfattning : The topic of this thesis is the intersection of a structured hexahedral grid and one or more triangle meshes. The interest in the problem has arisen in connection with a finite volume method for simulation of conjugated heat transfer. LÄS MER

  7. 20. Topics in Content Based Image Retrieval : Fonts and Color Emotions

    Författare :Martin Solli; Reiner Lenz; Jan Erik Solem; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; image analysis; content based image retrieval; font recognition; color emotions; Image analysis; Bildanalys;

    Sammanfattning : Two novel contributions to Content Based Image Retrieval are presented and discussed. The first is a search engine for font recognition. The intended usage is the search in very large font databases. The input to the search engine is an image of a text line, and the output is the name of the font used when printing the text. LÄS MER
