  1. 1. Sunspot structure and dynamics

    Author : Luc Rouppe van der Voort; Wolfgang Schmidt; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Astronomi; Astronomy; astronomi;

    Abstract : Fundamental physical processes occur on small spatial scales in the solar atmosphere and high-spatial-resolution observations are necessary to test theoretical models. This thesis presents high-spatial-resolution observations of sunspots obtained with the Swedish solar telescopes on La Palma: the Swedish Vacuum Solar Telescope (SVST) and its successor the Swedish 1-m Solar Telescope (SST).

  2. 2. Equilibrium and Dynamics on Complex Networkds

    Author : Gino Del Ferraro; Erik Aurell; Bernard Derrida; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Statistical mechanics; complex networks; spin systems; non equilibrium dynamics; generalized belief propagation; message passing; cavity method; variational approaches; Fysik; Physics;

    Abstract : Complex networks are an important class of models used to describe the behaviour of a very broad category of systems which appear in different fields of science ranging from physics, biology and statistics to computer science and other disciplines. This set of models includes spin systems on a graph, neural networks, decision networks, spreading disease, financial trade, social networks and all systems which can be represented as interacting agents on some sort of graph architecture.

    Abstract : This thesis presents results of a series of experimental studies on the spreading dynamics of small drops of complex solutions on solid surfaces. The capillary flow dynamics of complex solutions have also been investigated. READ MORE

  4. 4. Dynamic Wetting of Solid Surfaces, Influence of Surface Structures and Surface Active Polymers

    Author : Stina Gerdes; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; stick-slip; Wilhelmy plate; block copolymers; surface active polymers; surface channels; spreading; contact angles; dynamic wetting; surface structures; Fysikalisk kemi;

    Abstract : The effect of surface structures on the dynamics of wetting was investigated through measurements of the dynamic contact angle and spreading velocity of oil droplets spreading over surfaces with parallel and gridlike V-shaped channels. A rim of liquid was observed to spread out in the channels ahead of the dropfront after a short time of spreading (seconds). READ MORE

  5. 5. Rapid wetting - influence of surface geometry and fluid properties

    Author : Susumu Yada; Fredrik Lundell; Shervin Bagheri; Minh Do-Quang; Gustav Amberg; Jacco Snoeijer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wetting; spreading; surface structures; droplet; contact line; two-phase flow; non-Newtonian flow; Engineering Mechanics; Teknisk mekanik;

    Abstract : Wetting of a liquid on a solid surface is ubiquitous in everyday life, such as morning dew on a plant leaf and raindrops hitting on a glass window. However, this phenomenon is far away from being completely understood. READ MORE
