  1. 1. Footbridge Dynamics : Human-Structure Interaction

    Author : Emma Zäll; Raid Karoumi; Mahir Ülker-Kaustell; Andreas Andersson; Peter Van den Broeck; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamics; vibration; footbridge; pedestrian bridge; human-structure interaction; runner; running loads; simplified models; Dynamik; vibration; gångbro; människa-bro-interaktion; löpare; löparlaster; förenklade modeller; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : For aesthetic reasons and due to an increased demand for cost-effective and environmentally friendly civil engineering structures, there is a trend in designing light and slender structures. Consequently, many modern footbridges are susceptible to excessive vibrations caused by human-induced loads. READ MORE

  2. 2. Exploring the Molecular Dynamics of Proteins and Viruses

    Author : Daniel Larsson; David van der Spoel; Modesto Orozco; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; molecular dynamics; virus dynamics; capsid dissolution; satellite tobacco necrosis virus; satellite tobacco mosaic virus; virus genome structure; gas phase protein structure; water layer; micelle embedded protein; membrane protein; Chemistry with specialization in Biophysics; Kemi med inriktning mot biofysik;

    Abstract : Knowledge about structure and dynamics of the important biological macromolecules — proteins, nucleic acids, lipids and sugars — helps to understand their function. Atomic-resolution structures of macromolecules are routinely captured with X-ray crystallography and other techniques. READ MORE

  3. 3. Adaptive Finite Element Procedures in Structural Dynamics

    Author : Xiangdong Li; Chalmers University of Technology; []
    Keywords : finite element; h-adaptivity; Newmark method; structural dynamics; space-time; a posteriori; superconvergent patch recovery; postprocessing; automatic time-stepping; semidiscretization; error estimation; discontinuous Galerkin;

    Abstract : This thesis deals with a posteriori error estimation and adaptivity in finite element procedures for the analysis of structural dynamic problems. First, error estimation and adaptivity for the Newmark time integration method are studied. READ MORE

  4. 4. Carbody and Passengers in Rail Vehicle Dynamics

    Author : Pelle Carlbom; KTH; []
    Keywords : Rail-Vehicle Dynamics; Human-Body Dynamics; Ride Comfort; Structural Dynamics;

    Abstract : The carbody plays an important role in rail vehicle dynamics.This thesis aims atdeveloping validated modelling methods tostudy its dynamics, how it is excited on trackand how itinteracts with the passengers. The primary interest is ridecomfort,considering vibrations up to 20 Hz. READ MORE

  5. 5. Input Estimation in Structural Dynamics

    Author : Lars Nordström; Chalmers University of Technology; []
    Keywords : sensitivity analysis; dynamic programming; input estimation; load identification; ill-posedness; regularization; indirect force measurement; inverse problems;

    Abstract : Knowledge of time-varying excitation is of importance in the design of a wide range of engineering applications, from spacecraft and processing plants to electronic circuits. Regardless of the actual application or underlying physics, the expected input will play a key role in the determination of adequate system properties and parameters. READ MORE
