  1. 1. Experimental design and vortex analyses in turbulent wake flows

    Författare :Bengt E. G. Fallenius; Jens H. M. Fransson; Henrik Alfredsson; Marianna Braza; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bluff bodies; wake flow; experimental design; vortex detection; flow control; asymptotic suction boundary layer;

    Sammanfattning : A new experimental setup for studies on wake flow instability and its control that successfully has been designed and manufactured, is introduced and de- scribed. The main body is a dual-sided flat plate with an elliptic leading edge and a blunt trailing edge. LÄS MER

  3. 2. Adaptive Mesh Refinement and Simulations of Unsteady Delta-Wing Aerodynamics

    Författare :Yann Le Moigne; KTH; []
    Nyckelord :delta wing; high angle of attack; vortex; pitching; mesh refinement; UCAV; vortex sensor; tensor ofvelocity gradients;

    Sammanfattning : This thesis deals with Computational Fluid Dynamics (CFD)simulations of the flow around delta wings at high angles ofattack. These triangular wings, mainly used in militaryaircraft designs, experience the formation of two vortices ontheir lee-side at large angles of attack. LÄS MER

    Författare :Chenyu Wen; Shi-Li Zhang; Zhen Zhang; Ulrich F. Keyser; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solid-state nanopore; ionic current; current blockage; effective transport length; noise; surface charge; translocation; biomolecule; electroosmotic flow; vortex; autogenic translocation; multiple nanopores; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : Nanopore based sensing technology has been widely studied for a broad range of applications including DNA sequencing, protein profiling, metabolite molecules, and ions detection. The nanopore technology offers an unprecedented technological solution to meeting the demands of precision medicine on rapid, in-field, and low-cost biomolecule analysis. LÄS MER

  5. 4. Automated feature detection in multidimensional images

    Författare :Einar Heiberg; Carlos Alberola; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Manual identification of structures and features in multidimensional images is at best time consuming and operator dependent. Feature identification need to be accurate, repeatable and quantitative.This thesis presents novel methods for automated feature detection in multidimensional images that are independent on imaging modality.
