  2. 1. 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

  4. 2. Active Matter in a Critical State: From passive building blocks to active molecules, engines, and active droplets

    Author : Falko Schmidt; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; active matter; nonequilibrium; self-assembly; microswimmers; nanomotors; optical tweezers; colloidal molecules; active droplets; critical Casimir forces;

    Abstract : The motion of microscopic objects is strongly affected by their surrounding environment. In quiescent liquids, motion is reduced to random fluctuations known as Brownian motion. Nevertheless, microorganisms have been able to develop mechanisms to generate active motion. READ MORE

  5. 3. Dynamics of Biomembranes and Rheological Properties of Living Cells

    Author : Peter Berntsen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cell mechanics; lipid dynamics; cell rheology; biomembranes; water dynamics; relaxations; phospholipids; glass transition;

    Abstract : An ingenious assembly of biomolecules and water constitute what we call biological tissue. The presence of water in this assembly is fundamental for the physiological processes and can make the difference between life and death. READ MORE

  6. 4. Controlling the Roll Responses of PCTC's

    Author : Carl-Johan Söder; Jakob Kuttenkeuler; Dominic Hudson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PCTC; parametric roll; roll response; roll damping; rudder control; roll mitigation; racking;

    Abstract : Modern Panamax Pure Car and Truck Carriers (PCTC) have become more vulnerable to critical roll responses as built in margins have been traded against increased transport efficiency. The research presented in this licentiate thesis aims at enhancing the predictability and control of these critical roll responses. READ MORE

  7. 5. Steering Based Lateral Performance Control of Long Heavy Vehicle Combinations

    Author : Sogol Kharrazi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trailer Swing; Active Steering; Offtracking; Heavy Vehicle; Lateral Performance; Sine with Dwell; Accident Analysis; Longer Combination Vehicle; Rearward Amplification;

    Abstract : In this thesis the lateral performance of heavy vehicle combinations, specifically longer combination vehicles, is discussed. The use of longer combination vehicles is promoted by their positive impact on the traffic congestion problem, as well as their economic and environmental benefits due to reduced fuel consumption and emissions.
