  1. 11. A lumped element transformer model including core losses and winding impedances

    Författare :David Ribbenfjärd; Göran Engdahl; Arvid Broddefalk; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power transformer; hysteresis; dynamic hysteresis; eddy currents; excess eddy currents; leakage flux; winding model; core model; magnetic measurements; magnetic materials; Electrical engineering; Elektroteknik;

    Sammanfattning : In order to design a power transformer it is important to understand its internal electromagnetic behaviour. That can be obtained by measurements on physical transformers, analytical expressions and computer simulations. LÄS MER

  5. 14. Stochastic model updating and model selection with application to structural dynamics

    Författare :Majid Khorsand Vakilzadeh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element model; Bayesian model selection; Bayesian model updating; stochastic simulation; Bootstrapping; Subspace system identification; Uncertainty quantification;

    Sammanfattning : Uncertainty induced by our incomplete state of knowledge about engineering systems and their surrounding environment give rise to challenging problems in the process of building predictive models for the system behavior. One such challenge is the model selection problem, which arises due to the existence of invariably multiple candidate models with different mathematical forms to represent the system behavior, and so there is a need to assess their plausibility based on experimental data.

  7. 15. Predictive Modeling of Lake Eutrophication

    Författare :Jan Mikael Malmaeus; Lars Håkanson; Kurt Pettersson; Jürg Bloesch; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; mass balance model; dynamic model; mechanistic model; phosphorus; LEEDS; suspended particulate matter; settling velocity; sedimentation; accumulation sediments; burial; diffusion; climate scenario; Erken; Balaton; Kinneret; Batorino; Miastro; Naroch; Galten; Ekoln; Geovetenskap; Earth sciences; Geovetenskap;

    Sammanfattning : This thesis presents predictive models for important variables concerning eutrophication effects in lakes. The keystone is a dynamic phosphorus model based on ordinary differential equations. LÄS MER
