  1. 1. Turbulence Modelling of Flows Related to Wall-Cooling Applications

    Author : Stefan Jansson; Chalmers University of Technology; []
    Keywords : low-Reynolds number models; second-order-moment closures; turbulent heat transfer; two-equation models; film-cooling; near-wall models; turbulence modelling;

    Abstract : Engineering flows are generally characterised by complex strain field and turbulence structure arising from a combination of shear, curvature, separation and recirculation etc. Under such flow conditions, transport by turbulent velocity fluctuations can make a significant contribution to the transport of momentum, heat and mass.

  3. 3. Microstructure and Mechanical Properties of Magnetron Sputtered Refractory Metal Thin Films

    Author : Stefan Fritze; Ulf Jansson; Erik Lewin; Petr Vasina; Uppsala universitet; []
    Keywords : thin films magnetron sputtering; refractory metals; high entropy alloys; mechanical properties; transition metal carbides; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : The design and development of new multifunctional materials that exhibit a combination of high hardness and ductility, as well as a high corrosion resistance and thermal stability, is one of the key challenges in the field of material science. The focus of this thesis is on the development of novel multifunctional magnetron sputtered CrNbTaTiW–C based thin films. READ MORE

  4. 4. Geometry Calibration of IceCube : using Photon Timing from Downgoing Muons

    Author : Matti Jansson; Klas Hultqvist; Stefan Richter; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Abstract : The IceCube Neutrino Observatory at the South Pole has instrumented one cu-bic kilometer of ice by deploying digital optical modules (DOMs) in 86 drillholes, each containing a string of DOMs. So far IceCube has used the locationof the drill tower for the positions of DOMs in the transverse directions (x andy) to the vertical direction (z).

  5. 5. Harmonizing National Laws on Human Trafficking by Implementing Article 3 of the Palermo Protocol : Problems and Reform

    Author : Dominika Borg Jansson; Petter Asp; Stefan Hedlund; Per Ole Träskman; Uppsala universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Trafficking in human beings; international law; criminal law; organized crime; legal transplants; language; irregular migration; Palermo Protocol; human rights; women’s rights; Criminal Law; Straffrätt;

    Abstract : Trafficking in human beings is one of the most serious and acute problems of our time. It is seen as one of the main forms of organized crime as well as a modern form of slavery. Trafficking is a practice that affects entire societies or rather the very fabric of democratic societies. READ MORE
