  1. 1. Precise Image-Based Measurements through Irregular Sampling

    Författare :Teo Asplund; Robin Strand; Cris L. Luengo Hendriks; Matthew J. Thurley; Gunilla Borgefors; Hugues Talbot; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; image analysis; image processing; mathematical morphology; irregular sampling; adaptive morphology; missing samples; continuous morphology; path opening.; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Mathematical morphology is a theory that is applicable broadly in signal processing, but in this thesis we focus mainly on image data. Fundamental concepts of morphology include the structuring element and the four operators: dilation, erosion, closing, and opening. LÄS MER

  3. 2. Path planning using probabilistic cell decomposition

    Författare :Frank Lingelbach; Bo Wahlberg; Henrik I. Christensen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signalbehandling; Signal processing; Signalbehandling;

    Sammanfattning : The problem of path planning occurs in many areas, such as computational biology, computer animations and computer-aided design. It is of particular importance in the field of robotics. Here, the task is to find a feasible path/trajectory that the robot can follow from a start to a goal configuration. LÄS MER

  4. 3. (Re-)shaping regional economies : Regional innovation system dynamics and new industrial path development

    Författare :Johan Miörner; Institutionen för kulturgeografi och ekonomisk geografi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic geography; new path development; industrial change; regional innovation systems; reconfiguration; innovation policy; Structural change; agency; institutions; digital games; Automotive; IT; Scania; West Sweden; economic geography; new path development; industrial change; regional innovation system; reconfiguration; innovation policy; structural change; agency; institutions; digital games; automotive; IT; Scania; West Sweden;

    Sammanfattning : This dissertation explores the complexities of regional economic restructuring. It casts a light on how regional environments are ‘reconfigured’ in relation to the transformation of existing regional industries and the development of new ones. LÄS MER

  5. 4. Finite element procedures for crack path prediction in multi-axial fatigue

    Författare :Dimosthenis Floros; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fracture mechanics; Configurational forces; Mixed-mode; Numerical simulation; Rolling contact fatigue; Plasticity;

    Sammanfattning : Rolling Contact Fatigue (RCF) cracks in rails are among the most detrimental railway track defects regarding reliability and cost. The cracks typically grow in shear mode up to a certain length at which they might arrest or kink into a more tensile-driven growth. LÄS MER

  7. 5. Modelling Chemical Reactions : Theoretical Investigations of Organic Rearrangement Reactions

    Författare :Per-Erik Larsson; Sten Lunell; Nessima Salhi-Benachenhou; Olle Matsson; Osvaldo Goscinski; Ian H. Williams; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum chemistry; Kvantkemi; Quantum chemistry; Kvantkemi; Quantum Chemistry; Kvantkemi;

    Sammanfattning : Chemical reactions are ubiquitous and very important for life and many other processes taking place on earth. In both theoretical and experimental studies of reactivity a transition state is often used to rationalise the outcome of such studies. LÄS MER
