  1. 1. First-principles investigations of planar defects

    Author : Lu Song; Levente Vitos; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Two types of planar defects, phase interface and stacking fault, are addressed in this thesis. The investigation is mainly carried out for stainless steels which are fundamental materials in modern society. For the phase interface, we investigate the metallic bcc/bcc and fcc/bcc phase interfaces. READ MORE

  2. 2. First-principles investigations of planar defects

    Author : Song Lu; Levente Vitos; Graeme Ackland; KTH; []
    Keywords : ;

    Abstract : Two types of planar defects, phase interface and stacking fault, are addressed in thisthesis. The first-principles exact-muffin orbitals method in combination with thecoherent-potential approximation is the main density functional theory (DFT) toolfor our studies. READ MORE

  3. 3. Ab Initio Investigation of Interfacial and Grain Boundary Properties of Metals and Alloys

    Author : Changle Li; Levente Vitos; Song Lu; Hongbin Zhang; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : Phase interface (IF) and grain boundary (GB) are both common yet critical planar defects influencing the mechanical and physical properties of polycrystalline materials. Due to the complex nature of IFs and GBs in terms of structure and chemistry, determining the accurate excess energies associated with these defects is challenging for both experimental measurements and theoretical simulations.

  4. 4. Critical Scenario Identification for Testing of Autonomous Driving Systems

    Author : Qunying Song; Programvarusystem; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Software testing; Critical scenario identification; Autonomous systems; Autonomous driving systems;

    Abstract : Background: Autonomous systems have received considerable attention from academia and are adopted by various industrial domains, such as automotive, avionics, etc. As many of them are considered safety-critical, testing is indispensable to verify their reliability and safety.

  5. 5. Genetic organization of encapsulated and non-encapsulated Haemophilus influenzae strains. Analysis of the glpTQ and 23S rRNA operons

    Author : Xin-Ming Song; Malmö Klinisk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; intervening sequence; 23S rRNA; transcription; DNA sequence; glpT; Haemophilus influenzae; glpQ; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Encapsulated Haemophilus influenzae type b (Hib) and non-encapsulated H. influenzae (NTHi) are important pathogens causing invasive and mucosal infections in children. A 42 kDa surface-exposed lipoprotein, protein D, has been found to be a potential virulence factor of NTHi. READ MORE
