  1. 1. Dynamics of Molecular Adsorption on Metal Surfaces

    Författare :Christer Engdahl; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this Thesis different aspects of dissociative chemisorption and of scattering and trapping in a physisorption potential are investigated, mainly by means of classical trajectory calculations. In papers I-III the sticking coefficients of hydrogen on copper and nickel are calculated using a multidimensional effective-medium potential which takes the molecular orientation as well as the surface structure into account.

  4. 3. Analysis of Synchronous machine dynamics using a novel equivalent circuit model

    Författare :Christer Danielsson; Chandur Sadarangani; Göran Engdahl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synchronous machine; Equivalent circuit; Magnetic equivalent circuit model; Simulation model; Parameter determination; Electric power engineering; Elkraftteknik;

    Sammanfattning : This thesis investigates simulation of synchronous machines using a novel Magnetic Equivalent Circuit (MEC) model. The proposed model offers sufficient detail richness for design calculations, while still keeping the simulation time acceptably short. Different modeling methods and circuit alternatives are considered. LÄS MER
