  1. 21. Electronic speckle photography applied to in-plane deformation and strain field measurements

    Author : Mikael Sjödahl; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Abstract : Non-contacting measurements of deformation and strain fields are of great importance in experimental mechanics. This thesis describes the development and applications of a video-based, computerized system called electronic speckle photography that measures the in-plane deformation of a strained body.

  2. 22. Monitoring winter road friction using floating car data

    Author : Sofia Sollén; Johan Casselgren; Mikael Sjödahl; Hawzheen Karim; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Floating Car Data; Winter Road Maintenance; Tire-to-Road Friction; Road Safety; Vision Zero; Intelligent Transport Systems; Experimental Mechanics; Experimentell mekanik;

    Abstract : More than a million people die every year due to road traffic accidents globally where one in five serious or fatal accidents occurs during severe weather conditions. Sweden is in the lead of Vision Zero, with the aim of zero casualties due to road traffic, and every year new countries and organisations accept the challenge of saving lives. READ MORE

  3. 23. Machine tool vibrations and violin sound fields studied using laser vibrometry

    Author : Kourosh Tatar; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Abstract : The knowledge of the dynamic behaviour of a milling process is very important for finding an optimum process window. In today's manufacturing industry the machining parameters are often predicted using experimental data from non-rotating spindles. READ MORE

  4. 24. Development of Methods to Investigate Pulmonary Arterial Smooth Muscle Cells under Hypoxia

    Author : Joel Wahl; Kerstin Ramser; Mikael Sjödahl; Fredrik Nikolajeff; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Abstract : Hypoxic pulmonary vasoconstriction (HPV) is a physiological response to localized alveolarhypoxia that is intrinsic to the pulmonary circulation. By hypoxia-induced contractionof pulmonary arterial smooth muscle cells (PASMCs), the pulmonary capillary bloodflow is redirected to alveolar areas of high oxygen partial pressure, thus maintaining theventilation-perfusion ratio.

  5. 25. 3D localization in digital holography from scattered light from micrometer-sized particles

    Author : Johan Öhman; Mikael Sjödahl; Per Bergström; Erik Olsson; Torbjörn Löfqvist; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital Holography; Polarization; Particle Scattering; Metrology; Experimentell mekanik; Experimental Mechanics;

    Abstract : When a particle is illuminated by a beam of light it will scatter and redistribute the light in all directions. How it scatters depends on the size, shape and refractive index of the particle. Additionally, it depends on the wavelength and polarization of the illuminating beam. READ MORE
