  1. 1. Water-Metal Surfaces : Insights from core-level spectroscopy and density functional theory

    Author : Theanne Schiros; Anders Nilsson; John Hemminger; Stockholms universitet; []
    Keywords : water; hydroxyl; metal; surfaces; x-ray spectroscopy; density functional theory; bonding; fuel cell; kemisk fysik; Chemical Physics;

    Abstract : Computational methods are combined with synchrotron-based techniques to analyze the structure and bonding of water and water plus hydroxyl at metal surfaces under UHV and at near-ambient conditions. Water-metal interaction plays a crucial role in a multitude of cosmic, atmospheric and biological phenomena as well as heterogeneous catalysis, electrochemistry and corrosion. READ MORE

  2. 2. Geometry and Critical Configurations of Multiple Views

    Author : Fredrik Kahl; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; algebra; algebraic geometry; field theory; Number Theory; Matematik; Mathematics; reconstruction; image sequence; absolute conic; critical motions; critical surfaces; perspective projection; affine geometry; Euclidean geometry; multiple view geometry; projective geometry; group theory; Talteori; fältteori; algebraisk geometri; gruppteori; Mathematical logic; set theory; combinatories; Matematisk logik; mängdlära; kombinatorik;

    Abstract : This thesis is concerned with one of the core problems in computer vision, namely to reconstruct a real world scene from several images of it. The interplay between the geometry of the scene, the cameras and the images is analyzed. READ MORE

  3. 3. Rough surfaces in contact : artificial intelligence and boundary lubrication

    Author : Marco Rapetto; Luleå tekniska universitet; []

    Abstract : Interacting surfaces are found in mechanical systems and components. Since engineered surfaces are not perfectly smooth, only a fraction of the nominal surface area is actually in contact. This fraction is denoted as the real area of contact, Ar, and is formed by the sum of the contact spots between the two touching surfaces. READ MORE

  4. 4. Searing apparent surfaces : infernal females in four early works of William Blake

    Author : Dee Drake; Alicia Ostriker; Stockholms universitet; []
    Keywords : HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; English language; Engelska språket; English; engelska;

    Abstract : This study explores the quality of the infernal as a specifically female expression of desire in William Blake's work. The contention is that the infernal constitutes an essential female element of the divine in Blake's early work but is demonized in the late work as an attribute of the Female Will. READ MORE

  5. 5. Thermohydrodynamics of sliding contacts with textured surfaces

    Author : Samuel Cupillard; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering mechanics - Fluid mechanics; Teknisk mekanik - Strömningsmekanik; Machine Elements; Maskinelement;

    Abstract : Hydrodynamic sliding contacts like those found in journal or thrust bearings are frequently encountered in various types of machinery from computers to large turbines. These contacts, involving a variation in film thickness, are used to generate pressure in the lubricant film and separate the surfaces in relative motion. READ MORE
