  2. 11. Faster. Stronger. Better? : designing for enhanced engagement of extreme sports

    Author : Rouien Zarin; Andreas Lund; Johan Redström; Ambra Trotto; Tom Djajadiningrat; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; constructive design research; design prototypes; prototypes; design research; research through design; embodiment; sports; interaction; technology; user experience; human computer interaction; tactile; feedback; design; design;

    Abstract : The human body is capable of very rich and complex movements and gestures which we use in everyday life to manipulate, navigate and negotiate the world around us—it is our interface for human experience. However, as technology advances it simultaneously shrinks, moving closer to our bodies, intertwining with the many facets of our lives and positions itself between our experiences of the physical environments around us.

  4. 12. Robust gas flow metering under extreme industrial conditions

    Author : Emil Martinson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Abstract : In this thesis, a different method for creating acoustic pulses that can be used in the ultrasonic spectrum is proposed. The aim is to develop a robust and reliable system that uses ultrasonic techniques, such as transit time or sing-around, to measure gas flows in extreme environments. READ MORE

  5. 13. Development of Microcomponents for Attitude and Communication Systems on Small Vehicles in Space and Extreme Environments

    Author : Kristoffer Palmer; Greger Thornell; Hugo Nguyen; Henrik Kratz; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Administrative Law; Förvaltningsrätt;

    Abstract : In this thesis, components intended for vehicles in space and other extreme environments have been realized using microsystems technology to facilitate miniaturized, yet high-performing systems beneficial for small spacecraft and other vehicles with limited size and power.Cold gas thrusters commonly used on spacecraft basically accelerate a gaseous propellant stored under high pressure.

  6. 14. Impact of feedback on the ISM of extreme starburst galaxies : The case of Haro 11

    Author : Veronica Menacho Menacho; Göran Östlin; Armando Gil de Paz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Galaxies; stellar feedback; ISM; Integral field spectroscopy; Astronomy; astronomi;

    Abstract : Blue compact galaxies (BCGs) are compact, metal-poor, starbursting galaxies with characteristics similar to what is expected for the young high-redshifted galaxies. BCGs are among the most active in producing a large number of massive star clusters, each containing thousands of massive stars. READ MORE

  7. 15. Wireless Sensor Network and Radio Wave Propagation in Harsh Environments

    Author : Mathias Grudén; Anders Rydberg; Erik Björnemo; Uppsala universitet; []
