  1. 6. Radial basis function methods for pricing multi-asset options

    Författare :Victor Shcherbakov; Elisabeth Larsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Sammanfattning : The price of an option can under some assumptions be determined by the solution of the Black–Scholes partial differential equation. Often options are issued on more than one asset. In this case it turns out that the option price is governed by the multi-dimensional version of the Black–Scholes equation. LÄS MER

  3. 7. Optimization of truck tyres selection

    Författare :Zuzana Nedelkova; Göteborgs universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; radial basis function; categorical variables; truck tyres; simulation-based optimization; surrogate model; approximately optimal solution; efficient solution; rolling resistance coefficient; vehicle dynamics; simulation-based optimization;

    Sammanfattning : This thesis, which consists of an introduction and five appended papers, concerns the optimal selection of tyres for a variety of vehicle configurations as well as operating environments. The selection problem stems from a project cooperation between Chalmers University of Technology and Volvo Group Trucks Technology. LÄS MER

  4. 8. English Colour Terms in Context

    Författare :Anders Steinvall; Gunnar Persson; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; English language; basic colour terms; elaborate colour terms; cognitive linguistics; metonymy; domain; context; markedness; figurative meaning; type modification; classifying function; vantage; reference point; attribute; entrenchment; radial category; corpus; English language; Engelska språket; engelska; English;

    Sammanfattning : This thesis examines usage of English colour terms in context, based on an extensive computerised text corpus, the Bank of English. It describes the ways in which English colour terms may be used to refer to nuances outside their normal area of designation and to attributes outside the colour domain. LÄS MER

  5. 9. Mathematical modelling for optimization of truck tyres selection

    Författare :Zuzana Sabartova; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; simulation-based optimization; truck tyres selection; surrogate model; radial basis function interpolation; rolling resistance coefficient; combinatorial set of problem instances; global optimization; global optimization;

    Sammanfattning : This thesis, which consists of an introduction and three appended papers, concerns the optimal selection of tyres for a given vehicle configuration and an operating environment in which the vehicle is to be used. The optimization problem stems from an industrial project performed in cooperation between Chalmers University of Technology and Volvo Group Trucks Technology (GTT). LÄS MER

  7. 10. Numerical Methods for Aerodynamic Shape Optimization

    Författare :Olivier Amoignon; Martin Berggren; Per Lötstedt; Olivier Pironneau; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computational Fluid Dynamics; shape optimization; adjoint equations; edge-based finite-volume method; moving mesh adaptation; radial basis functions; inviscid compressible flow; transition control; Numerical Analysis; Numerisk analys;

    Sammanfattning : Gradient-based aerodynamic shape optimization, based on Computational Fluid Dynamics analysis of the flow, is a method that can automatically improve designs of aircraft components. The prospect is to reduce a cost function that reflects aerodynamic performances. LÄS MER
