  1. 1. Biomechanical investigation of the efficacy and perceived performance of a knee brace

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Alice Garnheim; Alvina Vernersson; [2023]
    Nyckelord :Biomechanical investigation; knee brace; osteoarthritis; design; OA; healthy subjects; gait analysis; Technology and Engineering;

    Sammanfattning : The most prevalent joint disease in adults is osteoarthritis. The knee joint is the joint which is the most affected by osteoarthritis, with mechanical overloading being one of the causes. While no cure exists for osteoarthritis, many different treatment options are available. One alternative is to wear a knee brace on the affected leg. LÄS MER

  3. 2. General Defocus Particle Tracking

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Joakim Anderberg; [2023]
    Nyckelord :General Defocus Particle Tracking; ultrasonic standing waves; microscopy; microchip; single plane particle tracking; levitation; Generel ur-fokus partikel spårning; stående ultraljudsvågor; mikroskopi; mikorchip; enkelplans partikel spårning; levitation;

    Sammanfattning : Three-dimensional particle tracking is a valuable tool in microfluidics for obtaining information about a system. General Defocus Particle Tracking (GDPT) is a straightforward method of 3D particle tracking that only requires a single-camera plane, making it applicable to existing equipment in a laboratory.

  4. 3. Phase-Contrast Imaging, Towards G2-less Grating Interferometry With Deep Silicon

    Master-uppsats, KTH/Fysik

    Författare :Rickard Brunskog; [2022]
    Nyckelord :Phase-contrast imaging; phase-contrast; CT-scanning; Computed-tomography; 1 micrometer resolution x-ray; grating-less phase-contrast imaging; Faskontraströntgen; faskontrast; CT-skanning; 1 mikrometer upplösning x-ray; gitterlös faskontrast; datortomografi;

    Sammanfattning : Conventional phase-contrast imaging entails stepping an analyser grating across the detector to resolve the interference pattern caused by the x-rays after passing through a series of gratings in a so-called Talbot-Lau interferometer. However, the analyser grating in the interferometer poses a challenge, not only due to the machinery and alignment required but also due to each exposure delivering a dose to the subject. LÄS MER

  5. 4. Dark pathways : cows’ walking behavior in dim light environments

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Kajsa Ståhlberg; [2022]
    Nyckelord :night light; illumination; locomotion; activity; intensity; color; distribution; obstacle course;

    Sammanfattning : Swedish dairy cows should have access to dim light at night according to the animal welfare act, but there are no further recommendations stated for dim light management regarding light intensity, light color, or light distribution. This study aimed to examine the effects of five dim light intensities, in red and white light color, and in even and uneven light distribution on cows’ walking behavior in an obstacle course.

  7. 5. Visuomotor coordination in people with nearsightedness : A study on gaze and lower body movement

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Zhaoyuan Wan; [2022]
    Nyckelord :Visuomotor coordination; gait analysis; gaze behaviour; nearsightedness; motion capture; eye-tracking;

    Sammanfattning : At least 2.6 billion people all over the world suffer from nearsightedness, among whom 312 million are under 19 years old. Just like other vision problems, uncorrected nearsightedness brings inconvenience to many human daily activities including walking. LÄS MER
