  2. 1. High speed imaging analysis of laser welding

    Author : Ingemar Eriksson; William O’Neill; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Abstract : Laser welding is often considered a new and exotic manufacturing method even though it has been used in industrial applications for nearly fifty years. In the early years only a few special applications justified the high investment cost involved, but as the price of the laser sources has reduced, industrial interest in laser welding has increased.

  4. 2. High strain-rate experiments using high-speed photography

    Author : Jörgen Kajberg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : In many technical processes, material is deformed under conditions that contain high strain rates. Examples of such processes are collisions, impact, penetration, metal forming and crack propagation. Constitutive models including viscoplasticity have been proposed for these kinds of situations.

  5. 3. Semi-Autonomous Navigation of Powered Wheelchairs : 2D/3D Sensing and Positioning Methods

    Author : Cristian Vilar; Mattias O'Nils; Silvia Krug; Nicolas Ragot; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 3D object recognition; YOLO; YOLO-Tiny; 3DHOG; Histogram-of-Oriented-Gradients; ModelNet40; Feature descriptor; Intel RealSense; Depth camera; Wheelchair;

    Abstract : Autonomous driving and assistance systems have become a reality for the automotive industry to improve driving safety in the car. Hence, the cars use a variety of sensors, cameras and image processing techniques to measure their surroundings and control their direction, braking and speed for obstacle avoidance or autonomously driving applications.

  6. 4. Laser Diagnostic Techniques with Ultra-High Repetition Rate for Studies in Combustion Environments

    Author : Jimmy Olofsson; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High-Speed; High Repetition Rate; LIF; PLIF; 3D Visualisation; Engine; Teknik; Technological sciences; Fysik; Physics; Combustion; Laserteknik; Laser technology; Laser-Induced Fluorescence; Laser Diagnostics;

    Abstract : When conducting laser based diagnostics in combustion environments it is often desirable to obtain temporally resolved information. This can be due to several factors such as combustion taking place in a turbulent flow field, flame propagation from a spark plug in an initially quiescent combustible mixture, or rapid, multi-point fuel consumption in a homogeneous charge as a result of compression ignition in an engine cycle.
