  1. 1. Combustibility study of resin for warm magnet coils used at CERN

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Juan Carlos Lopez Santiago; [2023]
    Nyckelord :Epoxy resin; flammability; radiation; aging; cone calorimeter; micro combustion calorimeter; thermogravimetric analysis; lateral ignition and flame spread test; chemical composition of polymers; polymers; epoxy composite; polymer composite; failure of epoxy resins; magnetic coil; Technology and Engineering;

    Sammanfattning : CERN is the world's largest particle physics laboratory, housing multiple accelerators that rely heavily on magnetic coils. These coils are integral to the generation of powerful magnetic fields essential for particle accelerator experiments, detectors, and other equipment. LÄS MER

  3. 2. EV battery temperature estimation : Designing a model for minimal temperature of high-voltage battery in a BEV

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för data- och elektroteknik (2023-)

    Författare :Björn Arvidsson; [2023]
    Nyckelord :BEV; temperature estimation; lowpass filter; BEV; lågpassfilter; temperaturestimering;

    Sammanfattning : Fordonsindustrin är inne i ett skifte, där förbränningsmotorer (ICE) bör-jar fasas ut och det satsas mer på eldrift med hjälp av batterier (BEV).  I detta arbete, som efterfrågades av Volvo Cars, utvecklades en matema-tisk modell som uppskattar den lägsta temperaturen i en elbils högspän-ningsbatteri.

  4. 3. Wrist Angle Estimation Using Two Wearable Inertial Measurement Units

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Arvin Razavi; [2023]
    Nyckelord :IMU wrist angle estimation; Wrist absolute angle; IMU-based human motion capture; orientation filter; Complementary filter; Kalman filter; IMU handledsvinkeluppskattning; handleds absolutvinkel; IMU-baserad mänsklig rörelsefångst; orienteringsfilter; komplementfilter; Kalman-filter;

    Sammanfattning : Hand-intensive work is closely related to the prevalence of upper body and hand/wrist work-related musculoskeletal disorders (WMSDs) in office work, manufacturing, service industries, as well as the healthcare industry. Some risk factors include vibrations, forceful exertions, heavy manual handling, repetitive motions, and prolonged nonneutral wrist postures. LÄS MER

  5. 4. Evaluating an increased spill regime as a management tool to improve downstream passage of salmon smolt

    Master-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Författare :Mattias Hansson; [2022]
    Nyckelord :hydraulic modeling; hydroacoustic telemetry; time to event analysis; hydraulisk modellering; överlevnadsanalys; hydroakustisk telemetri;

    Sammanfattning : The anadromous Atlantic salmon (Salmo salar) is dependent on river connectivity to reach spawning and rearing habitats in rivers. Most rivers are today fragmented by artificial barriers such as hydroelectric powerplants (HEP) which impede this migratory movement. LÄS MER

  7. 5. Ambient temperature and risk of preterm birth in three Nepalese regions from March 2019 to May 2020: a retrospective secondary data analysis using distributed lag non-linear models

    Master-uppsats, Uppsala universitet/Institutionen för kvinnors och barns hälsa

    Författare :Katharina Albert; [2022]
    Nyckelord :preterm birth; ambient temperature; neonatology; Nepal; DLNM;

    Sammanfattning : Background: Preterm birth is a global health problem which causes significant short- and long-term morbidity and mortality. Pathophysiology is not entirely clear and due to climate change environmental risk factors, such as extreme temperatures, should be considered as emerging and modifiable risk factors. LÄS MER
