  1. 21. On the multiscale modeling of duplex stainless steel

    Författare :Robert Lillbacka; RISE; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; duplex stainless steel; crystal plasticity; damage; Concurrent multiscale modeling; calibration;

    Sammanfattning : This thesis deals with the modeling and simulation ofthe influence of the material substructure on the macroscopicmechanical properties of duplex stainless steel (DSS). Twosubscale levels and their interaction are considered: Grainstructure (mesoscale) and crystallographic structure (microscale). LÄS MER

  3. 22. Utilization of a GSHP System in a DHC Network : modeling and optimization

    Författare :Anjan Rao Puttige; Thomas Olofsson; Ronny Östin; Staffan Andersson; Javed Saqib; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ground source heat pump; district heating and cooling; optimization; borehole heat exchanger; artificial neural network; hybrid model; field measurements; calibration; heat pumps; prosumer;

    Sammanfattning : The ground source heat pumps (GSHPs) of customers connected to the district heating and cooling (DHC) network can benefit both the customer and the energy company. However, operating the GSHP to minimize the cost of providing heating and cooling to the customer while ensuring the long-term stability of the ground temperature is a challenge. LÄS MER

  4. 23. Deep neural networks for electromagnetics applied to optimization and inverse problems

    Författare :Simon Stenmark; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calibration; optimization; Inverse problems; normalization; deep learning; neural networks;

    Sammanfattning : This thesis explores the possibilities to complement full-wave electromagnetic solvers with fully-connected neural networks. We emphasize problems that must be solved a very large number of times in a limited parameter domain. We present and evaluate the normalization method ForwardNorm. LÄS MER

  5. 24. Statistical Calibration Algorithms for Lidars

    Författare :Anas Alhashimi; Steffi Knorn; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : Robots are becoming increasingly available and capable, are becoming part of everyday life in applications: robots that guide blind or mentally handicapped people, robots that clean large office buildings and department stores, robots that assist people in shopping, recreational activities, etc.Localization, in the sense of understanding accurately one's position in the environment, is a basic building block for performing important tasks.

  7. 25. Asymptotic Analysis of Hedging Errors Induced by Discrete Time Hedging

    Författare :Mats Brodén; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Discrete time hedging; discretization error; L2 convergence; Non-linear Kalman filters; Calibration;

    Sammanfattning : The first part of this thesis deals with approximations of stochastic integrals and discrete time hedging of derivative contracts; two closely related subjects. Paper A considers the problem of approximating the value of a Wiener process. LÄS MER
