  1. 1. Towards accurate modeling of moving contact lines

    Författare :Hanna Holmgren; Gunilla Kreiss; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Sammanfattning : The present thesis treats the numerical simulation of immiscible incompressible two-phase flows with moving contact lines. The conventional Navier–Stokes equations combined with a no-slip boundary condition leads to a non-integrable stress singularity at the contact line. LÄS MER

  3. 2. Space in motion : the art of activating space in-between

    Författare :Monica Sand; Abdellah Abarkan; Annette Arlander; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; in-between; dispersed production; producer observer; bridge; swing; penelope; Architecture; Arkitektur; Art; Konstvetenskap;

    Sammanfattning : As a contribution to the emerging field of practice-based research in the arts, this thesis aims to activate space, experience and the concept in-between. As the in-between cannot be defined ahead of the rhythmic process it carries out and of which it is a part – a rhythm inherent in the city itself and in knowledge production – it is necessary to produce rhythmic relations between bodies, sites and concepts.

  4. 3. Using the Work and Organizational Psychology Perspective in Research on Agile Software Development Teams

    Författare :Lucas Gren; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Software Engineering; Work and Organizational Psychology; Agile Software Development; Empirical Research; Group Development; Empirical Research;

    Sammanfattning : Background: The development of software has gone from more strict plan-driven projects to involve more human interaction and communication due to approaches like agile software development. With the realization of the importance of psychological aspect comes the possibility of learning from other more established research fields instead of reinventing the wheel. LÄS MER

  5. 4. Train---Track Interaction. Coupling of Moving and Stationary Dynamic Systems: Theoretical and Experimental Analysis of Railway Structures Considering Wheel and Track Imperfections

    Författare :Jens Nielsen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : A general and well-structured method is advanced for analysis of the vertical dynamic interaction between a train and its track. The trains studied are modelled as linear or non-linear discrete mass-spring-damper systems. LÄS MER

  7. 5. Inverse Problems in Tomography and Fast Methods for Singular Convolutions

    Författare :Fredrik Andersson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik; Unequally spaced FFT; Integral transforms; Singular integrals; Lippmann?Schwinger equation; Helmholtz equation; Inverse problems; Fast Gauss transform; Fast summation; Convolution; Radon transform; Tomography;

    Sammanfattning : There are two, partially interlaced, themes treated in this thesis; inverse problems of tomographic type and fast and accurate methods for the application of convolution operators. Regarding the first theme, the inverse problem of Doppler tomography is considered and the Doppler moment transform is introduced for that purpose. LÄS MER
