  1. 1. Sampling-based Path Planning for an Autonomous Helicopter

    Författare :Per Olof Pettersson; Patrick Doherty; Lars Karlsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Path Planning; Motion Planning; Helicopters; Probabilistic Roadmaps; Rapidly-exploring Random Trees; Computer science; Datalogi;

    Sammanfattning : Many of the applications that have been proposed for future small unmanned aerial vehicles (UAVs) are at low altitude in areas with many obstacles. A vital component for successful navigation in such environments is a path planner that can find collision free paths for the UAV. LÄS MER

  3. 2. Optimizing prehospital acute stroke care in the presence of economic constraints

    Författare :Nicklas Ennab Vogel; Lars-Åke Levin; Tobias Andersson Granberg; Sofie Pilemalm; David Epstein; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Mechanical thrombectomy (MT) has become standard of care for acute anterior circulation ischaemic stroke due to large vessel occlusion since the launch of second-generation stent retrievers for clinical use nearly a decade ago. Up until recently, the treatment was exclusively performed at university hospitals in Sweden. LÄS MER

  4. 3. Exploring student collaboration during Data Generation in the Statistics Classroom : An Inferentialist Perspective

    Författare :Abdel Seidouvy; Maike Schindler; Ola Helenius; Dani Ben-Zvi; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inferentialism; Collaboration; Data generation; Statistics;

    Sammanfattning : This dissertation explores student collaboration during data generation in statistics. The first aim is to put the semantic theory of inferentialism to work and develop a theoretical lens for exploring student collaboration during data generation. LÄS MER

  5. 4. Noise and Vibration Control of Combustion Engine Vehicles

    Författare :Mathias Winberg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Noise and vibrations have over the last two decades been regarded as significant environmental health problems. Regulations regarding acoustic as well as vibration levels have therefore become more stringent. LÄS MER

  7. 5. Virtual Holonomic Constraints: from academic to industrial applications

    Författare :Daniel Ortiz Morales; Anton Shiriaev; Leonid Freidovich; Ivan Kalaykov; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Virtual Holonomic Constraints; modeling; control; motion planning; under-actuated systems; forestry cranes; hydraulic manipulators;

    Sammanfattning : Whether it is a car, a mobile phone, or a computer, we are noticing how automation and production with robots plays an important role in the industry of our modern world. We find it in factories, manufacturing products, automotive cruise control, construction equipment, autopilot on airplanes, and countless other industrial applications. LÄS MER
