  2. 16. Screen Printed Large Area Sensors for Pressure Distribution Monitoring in Wheelchairs

    Author : Jawad Ahmad; Johan Sidén; Henrik Andersson; Xavier Crispin; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : A sedentary lifestyle can induce health related problems including pressure ulcers. Pro­longed sitting inadequacies constitute a risk for pressure ulcer to many individuals, in particular people with disabilities and re­duced mobility. READ MORE

  4. 17. Tribology of polymer composites for elevated temperature applications

    Author : Jonna Lind; Åsa Kassman Rudolphi; Stefan Silverbåge; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tribology; polymer composite; friction; wear; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Abstract : Polymers as construction material are common in the industry. Although more recently the use of polymer composites in more demanding applications has increased, requiring more of them mechanically, tribologically and thermally. To enhance the properties various fillers are used, from common glass fibers to more advanced nanoparticles. READ MORE

  5. 18. High-speed 3D imaging of liquid jets, surfaces and respiratory droplets

    Author : Adrian Roth; Förbränningsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Laser Induced Fluorescence; Volumetric imaging; Structured Illumination; 3D Reconstruction; Stereoscopy; 3D Particle Tracking Velocimetry; COVID­19; sprays; respiratory droplets; Fysicumarkivet A:2023:Roth;

    Abstract : Sprays are commonly found in, among other, combustion, agriculture and food processing. For each of these applications, the understanding of spray liquid dynamics is crucial for optimization of efficiency, accuracy, and robustness of the spray­-system in use. READ MORE

  6. 19. Non-contact measurement systems in robotics and telerobotics

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

    Abstract : In robotics, and particularly in telerobotics, non-contact measurement methods are widely used. In this thesis, systems are investigated with the range camera as the main sensor component. It is desirable that remotely controlled robot systems have a high degree of autonomy. READ MORE

  7. 20. Case Studies in Ion Beam Assisted Nanostructure Engineering

    Author : Rajdeep Kaur; Petter Ström; Daniel Primetzhofer; Tuan Tran; Naureen Ghafoor; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ion irradiation; material modification; nanostructures; calcium fluoride; polyimide; etching; Fysik; Physics;

    Abstract : Beams of energetic ions can be used for material analysis and modification. It provides us with a tool featuring unique control over the area, depth and amount of damage in the material. This property of ion beams can be used to generate desired changes in material properties or form nanostructures with specific characteristics in the material. READ MORE
