  1. 1. Fluorescence studies of complex systems : organisation of biomolecules

    Författare :Denys Marushchak; Lennart B.A. Johansson; Alexander Lyubartsev; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fluorescence anisotropy; BODIPY; homo and hetero dimerisation; protein aggregates; protein polymer structures; actin polymerisation; FRET; donor–acceptor energy transfer DAET; donor-donor energy migration DDEM; homotransfer; Monte Carlo simulation; MC; Brownian dynamics; BD; Genetic Algorithm; GA.; Ganglioside GM1; Biophysical chemistry; Biofysikalisk kemi;

    Sammanfattning : The homo and hetero dimerisation of two spectroscopically different chromophores were studied, namely: 4,4-difluoro-4-bora-3a,4a-diazas-indacene (g-BODIPY) and its 5-styryl-derivative (r-BODIPY). Various spectroscopic properties of the r-BODIPY in different common solvents were determined. LÄS MER

  3. 2. Stiffness and vibration properties of slender tensegrity structures

    Författare :Seif Dalil Safaei; Gunnar Tibert; René Motro; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tensegrity booms; Tensegrity grids; Tensegrity power lines; Finite element analysis; Genetic algorithm; Flexibility analysis; Form-finding; Pre-stress design; Optimization;

    Sammanfattning : The stiffness and frequency properties of tensegrity structures are functions of the pre-stress, topology, configuration, and axial stiffness of the elements. The tensegrity structures considered are tensegrity booms, tensegrity grids, and tensegrity power lines.A study has been carried out on the pre-stress design. LÄS MER

  4. 3. Optimization of Point Absorber Wave Energy Parks

    Författare :Marianna Giassi; Malin Göteman; Jens Peter Kofoed; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave energy arrays; genetic algorithm; optimization; WEC; hydrodynamic interaction; Engineering Science; Teknisk fysik;

    Sammanfattning : Renewable energies are believed to play the key role in assuring a future of sustainable energy supply and low carbon emissions. Particularly, this thesis focus on wave energy, which is created by extracting the power stored in the waves of the oceans. LÄS MER

  5. 4. Model-based Analysis of Temporal Patterns in Atrioventricular Node Conduction During Atrial Fibrillation

    Författare :Mattias Karlsson; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atrial fibrillation AF ; Atrioventricular node; Mathematical modeling; Genetic algorithm GA ;

    Sammanfattning : The lifetime risk of developing atrial fibrillation (AF) is estimated to be between 1in 3 to 1 in 4 individuals, making it the most common arrhythmia in the world.For persistent AF, rate control drugs with the purpose to affect the conduction properties of the atrioventricular (AV) node are the most common treatment.
