  1. 1. Measurement and Application of Multidirectional Mobilities

    Författare :Michael A. Sanderson; Chalmers University of Technology; []
    Nyckelord :source signal filtering; mass loading; rotational mobility; rotational inertia loading; multidirectional mechanical mobility; moment mobility; structural intensity; measurement techniques; vibration isolation;

    Sammanfattning : The direct measurement of moment mobility, employing a twin exciter technique, is theoretically and experimentally examined. This is continued by a theoretical and experimental analysis of an improved technique using source signal filtering, for two degrees of freedom, for the measurement of multidirectional mobilities.

  2. 2. Multidirectional Mobilities - Advanced Measurement Techniques and Applications

    Författare :Lars H. Ivarsson; Chalmers University of Technology; []
    Nyckelord :R-DOFs; substructuring; measurement techniques; rotational mobility; multidirectional mechanical mobility; hybrid coupling; coupling; moment mobility; impedance coupling; consistency;

    Sammanfattning : Today high noise-and-vibration comfort has become a quality sign of products in sectors such as the automotive industry, aircraft, components, households and manufacturing. Consequently, already in the design phase of products, tools are required to predict the final vibration and noise levels. LÄS MER

  3. 3. Numerical modeling of dielectrophoresis

    Författare :Yuan Lin; Gustav Amberg; Olof Runborg; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dielectrophoresis; orientation of rotation; fluid particle dynamics; microparticle; molecular dynamics; hydrodynamics; particle-particle interaction; superimposed; mobility; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : We investigate the dielectrophoretic separation of microparticles. Two different models are formulated in two characteristic time scales. The first model mainly accounts for the orientation behavior and rotational motion of non-spheric microparticles. The concept of effective charge is suggested to calculate the finite size non-spheric particles. LÄS MER

  4. 4. Dynamics of Enzyme Immobilization in Mesoporous Silica Particles

    Författare :Pegah Sadat Nabavi Zadeh; Chalmers University of Technology; []
    Nyckelord :fluorescence spectroscopy; real-time monitoring.; fluorescence anisotropy; pore filling; Enzyme immobilization; mesoporous silica; kinetics; rotational mobility; rate of immobilization;

    Sammanfattning : The focus of this thesis is placed on the dynamic behavior of proteins in confining environments which is studied as a scientific challenge for a deeper understanding of the immobilization mechanism and a better designing of enzyme immobilization in porous materials. Enzymes are immobilized in porous materials to improve the enzyme activity and simplify their purification from the product solution in biocatalytic applications. LÄS MER
