  1. 11. Families of Sets Without the Baire Property

    Författare :Venuste Nyagahakwa; Vitalij Tjatyrko; Mats Aigner; Isidore Mahara; Vesko Valov; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The family of sets with the Baire property of a topological space X, i.e., sets which differ from open sets by meager sets, has different nice properties, like being closed under countable unions and differences. On the other hand, the family of sets without the Baire property of X is, in general, not closed under finite unions and intersections. LÄS MER

  3. 12. Turbulence modulation effects caused by small droplets using one-dimensional-turbulence

    Författare :Marco Fistler; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiphase Flow; Droplets; one-dimensional-turbulence ODT ; Turbulence;

    Sammanfattning : This thesis presents a stochastic model to study turbulence modulation effects on gas phases caused by small droplets or more generally speaking particles to achieve a better understanding about the physics and with the aim to provide data for a subgrid-scale (SGS) model for Large-eddy-simulations. The one-dimensional-turbulence (ODT) model addresses one of the major issues for multiphase flow simulations, namely computational costs. LÄS MER

  4. 13. Electro-optical properties of one-dimensional organic crystals

    Författare :Gleb Lobov; Sergei Popov; Lech Wosinski; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physics; Fysik;

    Sammanfattning : The recent development of photonics and applications puts new challenges for systems using emission, transmission and modulation of light. For these reasons, novel optical materials attract a special interest for their enabling properties for novel technologies. LÄS MER

  5. 14. Physical properties of coarse particles in till coupled to bedrock composition based on new 3D image analysis method

    Författare :Solomon Tafesse; Joanne Fernlund; Tore Påsse; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Three-dimensional shape; Grain size; Till lithology; Natural aggregate; Till provenance; Magnetic susceptibility of rock; Physical property of till; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; Geoengineering; Geoteknik;

    Sammanfattning : The physical properties of the coarse fraction of the till (0.4 to 20 cm) and the surface boulders have been studied at two different sites in Sweden. LÄS MER

  7. 15. Numerical study of primary breakup with One-Dimensional Turbulence

    Författare :Amirreza Movaghar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Most new engines will use direct injection of the fuel, making the fuel spray a critical part of the engine. Fuel spray behavior controls engine performanceand emissions and yet there is much that remains unknown about how a spray breaks up, mixes, evaporates and burns. LÄS MER
