  1. 1. Footbridge Dynamics Human-Structure Interaction

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Emma Zäll; KTH.; [2018]
    Keywords : 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. Imaging materials with intermodulation Studies in multifrequency atomic force microscopy

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Daniel Forchheimer; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; atomic force microscopy; nonlinear dynamics; frequency mixing; force reconstruction; Physics; Fysik;

    Abstract : The Atomic Force Microscope (AFM) is a tool for imaging surfaces at the microand nano meter scale. The microscope senses the force acting between a surfaceand a tip positioned at the end of a micro-cantilever, forming an image of the surface topography. READ MORE

  3. 3. Longitudinal Force Distribution and Road Vehicle Handling

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Matthijs Klomp; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ehicle dynamics; quasi steady-state; drive force; combined grip; longitudinal force distribution; combined slip; vehicle handling; optimization;

    Abstract : The distribution of longitudinal forces has a large influence on vehicle handling characteristics such as the driver/vehicle interaction, road holding and yaw stability, in particular during combined traction/braking and cornering near the grip limit of the tires. In order to select and develop suitable driveline systems and associated active control that provide consistent driver/vehicle handling, maximum road holding and sufficient yaw stability margins, it is essential to understand the influence of a particular drive force distribution on these handling characteristics.

  4. 4. Leibniz on Agency and Force

    University dissertation from Uppsala : Department of Philosophy, Uppsala University

    Author : Peter Myrdal; Uppsala universitet.; [2012]
    Keywords : HUMANIORA; HUMANITIES; Leibniz; Gottfried Wilhelm; 1646-1716; Early Modern Philosophy; Agency; Force; Final causes; Theoretical Philosophy; Teoretisk filosofi;

    Abstract : This is a study of Leibniz’s theory of agency – his theory of the nature of causal powers and agents. Leibniz develops his view against the background of an Aristotelian conception of agency. The latter was rejected by many early modern philosophers in the wake of the mechanist conception of the natural world. READ MORE

  5. 5. Force Budget Analysis of Glacier Flow Ice Dynamical Studies on Storglaciären, Sweden, and Ice Flow Investigations of Outlet Glaciers in Dronning Maud Land, Antarctica

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jim Hedfors; Uppsala universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical geography and sedimentology; force budget; ice flux; ice dynamics; mass balance; strain heating; climate change; Storglaciären; Dronning Maud Land; Antarctica; Naturgeografi och sedimentologi; NATURAL SCIENCES Earth sciences Exogenous earth sciences Physical geography; NATURVETENSKAP Geovetenskap Exogen geovetenskap Naturgeografi;

    Abstract : This thesis contributes to the understanding of glacier response to climate change by ice dynamical studies on Storglaciären, Sweden, and Bonnevie-Svendsenbreen, Kibergbreen and Plogbreen in Dronning Maud Land, Antarctica. Ice surface velocities, ice geometry and temperature information is fed through a force budget model to calculate ice mass outflux of these glacial systems via three-dimensional stress distributions for a flux-gate.
