  1. 1. Movement towards socioecological change: The case of Ecosomatics

    Kandidat-uppsats, Göteborgs universitet/Institutionen för globala studier

    Författare :Wilma Lagerman; [2024-03-19]
    Nyckelord :;

    Sammanfattning : Several scholars both within and outside the field of human ecology argue that the perceptual human-nature divide contributes profoundly to patterns of unsustainability and weak sustainability visible in the world today. Deliberately engaging in conscious bodily-felt contact with the natural environment is suggested to uncover appropriate, embodied angles to approaching ecology and the environmental crisis. LÄS MER

  3. 2. WEAR RESISTANT MULTI FUNCTIONAL POLYMER COATINGS

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Pranay Kumar Parsi; [2023]
    Nyckelord :Polymer coatings; Materials; Tribology; Wear resistant; Ice adhesion; Freezing delay; Anti-icing de-icing;

    Sammanfattning : This study aims to develop coatings which show wear resistant behaviour along with multiple functions such as improved ice adhesion, better freezing delay etc which help in improving the effectiveness of the wind turbine efficiency. The significance of anti-icing/de-icing solutions for wind turbines is emphasized since ice accretion can cause serious issues in generation of power and might lead to damage of blades. LÄS MER

  4. 3. Study and optimization of a hexacopter's composite structure

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Helena Delmotte; [2023]
    Nyckelord :Lightweight structure; Drone; Structural optimization; FEA; Lättviktsstruktur; Drönare; Strukturell optimering; FEA;

    Sammanfattning : Nowadays, the forestry industry still uses heavy machinery damaging both the forest and the soil. The start-up AirForestry is currently developing a sustainable way to thin and harvest trees. With their 6.2m wide electric drone carrying a harvesting tool, they can reach, thin, cut and carry trees without the need for access roads. LÄS MER

  5. 4. Heart Rate Measurement using a 60 GHz Pulsed Coherent Radar Sensor

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Melina Al Nasser; Linn Gromert; [2022]
    Nyckelord :Signal processing; EKG; Heart rate; Radar sensor; Neural network; Acconeer; Technology and Engineering;

    Sammanfattning : Heart rate is today measured in various ways, but they all include contact with the skin. Measuring heart rate contactless would be a more efficient method in healthcare and would also benefit people suffering from skin problems. It has been proven that it is possible to use radar to measure heart rate. LÄS MER

  7. 5. Effects of materials and texturing on wettability of ski base

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :ROSHAN SWAR; [2022]
    Nyckelord :Cross-country skiing; Stone grinding; UHMWPE;

    Sammanfattning : Cross-country skiing has turned into the most highly competitive winter sport, with skiers having the ability to win by merely milliseconds. Every year researchers, ski - technicians, and athletes come together to prepare the ski base surface that gives the best possible results. LÄS MER
