    Författare :Johan Malm; Dan Henningson; Philipp Schlatter; Suad Jakirlic; KTH; []
    Nyckelord :spectral-element method; direct numerical simulation DNS ; large-eddy simulation LES ; turbulence; transition; over-integration; three-dimensional separation; massively parallel simulations; proper orthogonal decomposition POD ; Koopman modes; vorticity stretching; coherence; SRA - E-vetenskap SeRC ; SRA - E-Science SeRC ;

    Sammanfattning : The spectral-element method (SEM) is used to study wall-bounded turbulent flowsin moderately complex geometries. The first part of the thesis is devoted to simulations of canonical flow cases, such as temporal K-type transitionand turbulent channel flow, to investigate general resolution requirements and computational efficiency of the numerical code nek5000.

  3. 7. Three-dimensional structure of oligosaccharides from molecular dynamics simulations

    Författare :Christer Höög; Lennart Nilsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; organisk kemi;

    Sammanfattning : This thesis focuses on the conformation and flexibility of oligosaccharides around the glycosidic linkage. The methods employed for the elucidation of the three-dimensional structures of biomolecules are briefly described. The main techniques used here are computer simulations and molecular dynamics simulations in aqueous solution in particular. LÄS MER

    Nyckelord :;

    Sammanfattning : Study I. Aims: Evaluate a collagen-PCL scaffold with minced bladder mucosa in vitro. M&M: Minced tissue was cultured on top of the scaffold. Scaffold properties were evaluated. LÄS MER

  5. 9. Fabrication of Group IV Semiconductors on Insulator for Monolithic 3D Integration

    Författare :Ali Asadollahi; Mikael Östling; Paul R. Berger; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; monolithic three dimensional M3D integration; strained germanium on insulator sGeOI pMOSFETs; silicon silicon-germanium on insulator sSOI sSiGeOI nMOSFETs; Si0.5Ge0.5 strain-relaxed buffer SRB ; direct bonding; chemical mechanical polishing CMP ; compressively strained GeOI; tensile strained Si0.5Ge0.5OI;

    Sammanfattning : The conventional 2D geometrical scaling of transistors is now facing many challenges in order to continue the performance enhancement while decreasing power consumption. The decrease in the device power consumption is related to the scaling of the power supply voltage (Vdd) and interconnects wiring length. LÄS MER

  7. 10. Grothendieck Rings and Motivic Integration

    Författare :Karl Rökaeus; Torsten Ekedahl; Johannes Nicaise; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Sammanfattning : This thesis consists of three parts: In Part I we study the Burnside ring of the finite group G. This ring has a natural structure of a lambda-ring. However, a priori the images of the G-set S under the lambda-operations can only be computed recursively. LÄS MER
