  1. 1. Elastic Properties of Nanowires - an Atomistic Evaluation

    Författare :Pär Olsson; Lund University.; Lunds universitet.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Nanowires constitute one of the fundamental building blocks in assembled nanodevices. Due to the high surface to volume ratio, the fraction of surface atoms is not negligible for nanosized elements. LÄS MER

  2. 2. Vibrations and Dynamic Isotropy in Hexapods - Analytical Studies

    Författare :Behrouz Afzali Far; Lund University.; Lunds universitet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The present work was initiated based on an industrial demand for designing a high-bandwidth hexapod of an advanced large optical telescope. In this dissertation, we have generalized this industrial problem to fully-parametric models of the hexapod vibrations as well as analytical studies on dynamic isotropy in parallel robots, which can be directly used in any hexapod application.

  3. 3. Arterial mechanics : noninvasive identification of constitutive parameters and residual stress

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Jonas Stålhand; Linköpings universitet.; Linköpings universitet.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis concerns the mechanical modelling of arteries, and particularly a method to identify parameters describing the mechanical properties using only clinically obtainable in vivo measurements. The artery is modelled as a fibre reinforced, incompressible, thick-walled cylinder subjected to large deformations and a residual stress field. LÄS MER

  4. 4. Phase Transitions in Large Oscillator Lattices

    Detta är en avhandling från Norbergsgatan 5A, 223 54 Lund

    Författare :Per Östborn; Lund University.; Lunds universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematisk och allmän teoretisk fysik; thermodynamics; statistical physics; phase transition; limit cycle oscillator; frequency entrainment; synchronization; sinus node; classical mechanics; Mathematical and general theoretical physics; arrhythmia; gravitation; quantum mechanics; relativity; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:2003:Östborn;

    Sammanfattning : This thesis deals with large networks of limit cycle oscillators. A limit cycle oscillator is a dynamical system that has a periodic attractor in phase space, and is defined in continuous time. To each such oscillator one can associate a natural frequency. LÄS MER

  5. 5. Active Control and Reduced-Order Modeling of Transition in Shear Flows

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Reza Dadfar; KTH.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRA - E-Science SeRC ; SRA - E-vetenskap SeRC ;

    Sammanfattning : In this thesis direct numerical simulation is used to investigate the possibilityto delay the transition from laminar to turbulent in boundary layer flows.Furthermore, modal analysis is used to reveal the coherent structures in highdimensional dynamical systems arising in the flow problems.
