  2. 11. Robust industrial automation software: outsets for non-determinism and real-time execution

    Author : Marcus Lindner; Alois Zoitl; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inbyggda system; Embedded Systems;

    Abstract : Studies about the industrial standard IEC 61499 and its relation to the RTFM Model of Computation represent the basis of this thesis. An overview of industrial automation software in general and in the scope of Svenska Kraftnät introduces the subject of software related issues. READ MORE

  4. 12. Photoelectron spectroscopy on strongly correlated systems

    Author : Oscar Tjernberg; KTH; []
    Keywords : ;

    Abstract : This work presents photoelectron spectroscopy data on somestrongly correlated systems. The electronic structure of the3dtransition metal oxides NiO and CoO have been studiedwith angle resolved and resonant photoemission. In the lattercase, both NiO and CoO show strong resonance effects at themetal absorption edges. READ MORE

  6. 14. Phase transitions in novel superfluids and systems with correlated disorder

    Author : Hannes Meier; Mats Wallin; Asle Sudbø; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; condensed matter physics; phase transitions; critical phenomena; spin models; quantum phase transitions; quantum fluids; superfluidity; superconductivity; disordered systems; Bose glass; dirty bosons; vortex pinning; statistical mechanics; Monte Carlo simulation; Wolff algorithm; classical worm algorithm; Wang-Landau algorithm; Fysik; Physics;

    Abstract : Condensed matter systems undergoing phase transitions rarely allow exact solutions. The presence of disorder renders the situation  even worse but collective Monte Carlo methods and parallel algorithms allow numerical descriptions. READ MORE

  7. 15. Multipoles in Correlated Electron Materials

    Author : Francesco Cricchio; Lars Nordström; Peter Oppeneer; Igor Solovyev; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; correlated electrons; magnetic ordering; multipoles; actinides; hidden order; high temperature superconductors; Fe pnictides; electronic structure calculations; Condensed matter physics; Kondenserade materiens fysik; Superconductivity; Supraledning; Electronic structure; Elektronstruktur; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : Electronic structure calculations constitute a valuable tool to predict the properties of materials. In this study we propose an efficient scheme to study correlated electron systems with essentially only one free parameter, the screening length of the Coulomb potential. READ MORE
