  1. 1. The growth of waves by wind as a problem in nonequilibrium statistical mechanics

    Författare :Anthony Bonfils; John Wettlaufer; Kristian Gustafsson; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; out-of-equilibrium system; fluctuation spectrum; oscillatory force; classical Casimir effect; non-linear waves; wave turbulence; wind-wave coupling.; teoretisk fysik; Theoretical Physics;

    Sammanfattning : In 1948, Casimir predicted a net attractive force between two perfectly conducting parallel plates due to electromagnetic vacuum fluctuations. By analogy, the interaction of two ships on a wavy sea has been named Maritime Casimir effect. This is an example of force generation in non-equilibrium systems. LÄS MER

  2. 2. Detailed analysis of slow oscillatory movements of eye position

    Författare :Bing Zhang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Our eyes make continuous movements even when attempting to fixate a stationary object. The involuntary eye movements occurring during fixation are referred to as fixational eye movements. There is a general agreement on three types of eye movements occurring during visual fixation: tremor, drift and microsaccade. LÄS MER

  3. 3. Numerical study of dense particle flows under planar shear

    Författare :Junhao Dong; Teoretisk kemi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dense suspension; granular flow; shear thickening; oscillatory flow; rheology; Discrete element method;

    Sammanfattning : In this thesis I conducted numerical simulations to study the flow behavior of dense particle flows composed of hard particles under planar shear using the discrete element method. The simulations were carried out in two dimensional systems, where the particles are modelled as circular discs. The discs are non-Brownian and neutrally buoyant. LÄS MER

  4. 4. Texture and color of potato products

    Författare :Sandra Segnini; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; potato processing; sensory evaluations; L*a*b*; French fries; potato chips; Texture; color; Food and drink technology; Livsmedelsteknik;

    Sammanfattning : Texture and color are the most important parameters in the definition of the quality of potato products, but usually their subjective measurements do not give any reproducible results due to the complicating factors related to human perception. In order to understand the factors that can affect the texture and the color of the potato products during processing, instrumental techniques have been developed for quantifying those parameters.

  5. 5. Quantum mechanical effects on charge transport in two mesoscopic systems

    Författare :Gustav Sonne; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanoelectromechanical systems; NEMS; carbon nanotubes; carbon peapods; excess current; superconducting weak links; suspended carbon nanotubes; non-linear resonances;

    Sammanfattning : Carbon nanotubes are one of the most promising building blocks for the developing field of nanoelectromechanics. Due to their unique electronic and mechanical properties, these all-carbon systems have been suggested for a range of applications where one wishes to utilse the coupling between mechanical and electronic degrees of freedom on the nanometer length scale.
