  1. 1. Triaxialförsök och utvärdering av parametrar för modellering : Anrikningssand med sprött beteende

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geoteknologi

    Författare :Lukas Haga; [2024]
    Nyckelord :Geoteknik; Triaxialförsök; Anrikningssand; Gruvdamm; Statisk liquefaction; NorSand; Utvärdering; Parametrar;

    Sammanfattning : Efter det dammbrott som skedde vid Brumadinho i Brasilien under januari 2019, där hundratals människor miste sina liv, har frågor kring statisk liquefaction hos anrikningssand fått stort fokus inom gruvdammsindustrin.  Statisk liquefaction kan modelleras med den konstitutiva modellen NorSand, där NorSand-parametrarna kan utvärderas från triaxialförsök.

  3. 2. DRIVER ENGAGEMENT User experience of static & dynamic interaction and engagement in Non-Driving Related Activities in Automated Vehicles - An experimental study

    Kandidat-uppsats, Institutionen för tillämpad informationsteknologi

    Författare :Elin Johansson; Sara Börjesson; [2023-05-19]
    Nyckelord :Non-Driving Related Activities; Take-over Request; SAE Level 4; Engagement; Situational Awareness; Self Assessment Manikin; The Contextual Control Model; Take-Over Scenario;

    Sammanfattning : The rapid development of automation in vehicles is reshaping the role of the driver and consequently changing driver behavior. This study is based on the SAE level 4 of automation, i.e the autonomous vehicle (AV) can drive fully autonomously in a conditioned area. LÄS MER

  4. 3. Monte Carlo evaluation of static and dynamic 6FFF treatments - Evaluation of dose distributions calculated with AAA, Acuros XB, and Collapsed Cone (RayStation and DoseCheck)

    Master-uppsats,

    Författare :Alma Blombäck; [2023-02-23]
    Nyckelord :Medical physics; Monte Carlo; 6FFF; AAA; Acuros XB; DoseCheck; RayStation; DVH evaluation; flattening filter free;

    Sammanfattning : There are several benefits to removing the standard flattening filter and using so-called flattening filter free (FFF) treatments in external radiation therapy with photons. The main advantage is the possibility of significantly shortening the treatment time, de spite this FFF is not widely used yet. LÄS MER

  5. 4. Evaluation and Optimization of LTE-V2X Mode 4 under Aperiodic Messages of Variable Size

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Md Mamunur Rashid; [2023]
    Nyckelord :LTE-V2X; aperiodic; variable size; CAM; Technology and Engineering;

    Sammanfattning : Vehicular networks connect vehicles for improved road safety and efficiency with the assistance of wireless information exchange. Vehicular networks are based on the frequent broadcast of awareness messages referred to as CAM (Cooperative Awareness Messages) or BSM (Basic Safety Message) in the ETSI and SAE standards, respectively.

  7. 5. Exploring patterns in risk factors for bark beetle attack during outbreaks triggered by drought stress with harvester data on attacked trees: A case study in Southeastern Sweden

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

    Författare :Nikolaos Kouskoulis; [2023]
    Nyckelord :Geography; GIS; Geographic Information Science; Forest ecosystems; Bark beetle outbreak; Southeastern Sweden; Predisposing factors; Triggering factors; Drought stress; Earth and Environmental Sciences;

    Sammanfattning : ABSTRACT Raising temperatures and climate variability have intensified extreme weather events worldwide. These extremes can enhance and trigger possible pest outbreaks. Bark beetle attacks have become a major concern in regions with extensive spruce forest areas. Southeastern Sweden has faced repeated outbreaks resulting in widespread tree loss. LÄS MER
