  1. 1. Improving AEB in winter conditions using road condition sensor

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Carl Jacob Edvinger; Moritz Breitbach; [2022]
    Nyckelord :AEB; aktiv säkerhet; fordonstest; styrrobot;

    Sammanfattning : Autonomous braking systems are becoming more common in modern cars. Autonomous EmergencyBraking (AEB) can help a driver avoid collision by automatically applying the brakes and stop thevehicle before an accident occurs. This can help save lives and reduce the risk of injuries in traffic.Previous work shows that AEB only works well on asphalt. LÄS MER

  3. 2. Fragmentation in graupel snow collisions

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Martanda Gautam; [2022]
    Nyckelord :Ecosystem Analysis; Clouds; Snow; Graupel; SIP; Fragmentation; CKE; Rime Fraction; Earth and Environmental Sciences;

    Sammanfattning : Aircraft observations of precipitating clouds with cloud top temperatures higher than -38°C have revealed that Secondary Ice Production (SIP) is responsible for presence of majority of ice particles. One such SIP mechanism is fragmentation via collisions between ice particles. LÄS MER

  4. 3. Snow-graupel collisions in clouds: a newly derived formulation for breakup of single crystals

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Victor Craig van der Brug; [2022]
    Nyckelord :Physical Geography and Ecosystem Analysis; Secondary Ice Production; Ice Cloud Number Concentration; Cloud Ice; Ice-Ice Collisions; Snow Crystal; Atmospheric Science Biogeochemical Cycles; Earth and Environmental Sciences;

    Sammanfattning : The observed and well-known discrepancy between concentrations of ice nucleating particles in the environment and the concentrations of ice particles in clouds show that there are additional ‘secondary’ processes enhancing the concentrations of ice particles. In present-day modelling of weather and climate, such processes are mostly overlooked and thus a cause for uncertainty. LÄS MER

  5. 4. Analysis of the Potential of Different Foam Materials in Face Protection to Reduce the Risk of Concussions in Ice Hockey

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Annika Neumann; [2021]
    Nyckelord :Ice Hockey Jaw Protection; FEM; Concussion; Foam;

    Sammanfattning :  Ice hockey players are at a high risk to sustain a concussion. Most of the concussion-inducing hits are to the jaw region, nevertheless, most players do not wear any protective gear shielding the jaw. LÄS MER

  7. 5. Concussions in Ice Hockey : Accident Reconstructions Using Finite Element Simulations

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Ekant Mishra; [2019]
    Nyckelord :Concussion; Ice hockey helmet; Accident reconstruction; FE; HBMs;

    Sammanfattning : Ice hockey, one of the most popular sports in the world, is a contact sport that is always associated with huge risks of traumatic brain injuries (TBIs) resulting from high-velocity impacts. Although technology in player protection equipment has advanced over the years, mild traumatic brain injuries (mTBIs) like concussion remain prevalent. LÄS MER
