  2. 1. Pluripolar Sets and Pluripolar Hulls

    Author : Tomas Edlund; Burglind Juhl-Jöricke; Norm Levenberg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; plurisubharmonic functions; pluripolar set; complete pluripolar set; pluripolar hull; fine topology; finely analytic function; fine analytic continuation; Matematisk analys; Mathematical analysis; Analys;

    Abstract : For many questions of complex analysis of several variables classical potential theory does not provide suitable tools and is replaced by pluripotential theory. The latter got many important applications within complex analysis and related fields. Pluripolar sets play a special role in pluripotential theory. READ MORE

    Author : Inka L. M. Locht; Igor Di Marco; Silke Biermann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dynamical mean field theory DMFT ; Hubbard I approximation; strongly correlated systems; rare earths; lanthanides; photoemission spectra; ultrafast magnetization dynamics; analytic continuation; Padé approximant method; two-particle Green s functions; linear muffin tin orbitals LMTO ; density functional theory DFT ; cerium; stacking fault energy.; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : In this work we study the interesting physics of the rare earths, and the microscopic state after ultrafast magnetization dynamics in iron. Moreover, this work covers the development, examination and application of several methods used in solid state physics. The first and the last part are related to strongly correlated electrons.

  6. 4. Modeling and Model Reduction by Analytic Interpolation and Optimization

    Author : Giovanna Fanizza; Anders Lindquist; György Michaletzky; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytic Interpolation theory with a degree constraint; rational covariance extension problem; spectral estimation; model reduction; optimization; passive system; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : This thesis consists of six papers. The main topic of all these papers is modeling a class of linear time-invariant systems. The system class is parameterized in the context of interpolation theory with a degree constraint. READ MORE

  7. 5. Costs and consequences in perioperative care : analytic models in studies on pain treatment and on haemodynamic optimization of elderly patients

    Author : Erzsebet Bartha; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Because resources are scarce in health care, costs and consequences of new interventions must be assessed to support informed policy decisions. This thesis analyses the cost-effectiveness of advanced postoperative pain treatment and perioperative haemodynamic optimization by applying decision modelling as an analytic framework. 1. READ MORE
