  1. 1. Effects of natural aging and low strain-rate on mechanical properties of aluminium alloy sheets used in automotive industry

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Amirhossein Gholami; Ali Abedisamarin; [2024]
    Nyckelord :Ageing. AA6014. AA6016;

    Sammanfattning : These days, lightweight materials such as aluminum alloy sheets, especiallythose in the AA6xxx series, are in high demand for use inthe automotive industry. During natural aging, the properties of aluminummay undergo significant changes due to the diffusion of atomswithin the crystal structure, impacting the strength and formabilityof aluminum sheets.

  3. 2. Beständigheten hos brandimpregnerat trä

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Filip Engström; Hannes Psajd; [2024]
    Nyckelord :Fire retardant treated wood; ISO 5660–1; Permanence; Euroclass; Cone Calorimeter; ConeTools; Infrared spectroscopy; Technology and Engineering;

    Sammanfattning : This report explores the properties of fire-retardant treated wood. This report has investigated the permanence for this material as well as seeing if the process of accelerated aging, which are used to determine the life span of the material, can be comparable to natural aging.

  4. 3. 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

  5. 4. Impact of aerosol dwell time on the survival of Mycobacterium tuberculosis

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Grisna Isabel Prensa; [2023]
    Nyckelord :;

    Sammanfattning : The airborne pathogen Mycobacterium tuberculosis (Mtb) is the causative agent of tuberculosis (TB) and claims about 1.6 million deaths annually (WHO, 2022). LÄS MER

  7. 5. Convolutional-LSTM for IGBTs Prognostics and Age Monitoring : Designing a neural network for predicting aging precursors in power devices

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Matteo Santoro; [2023]
    Nyckelord :Neural Networks; Igbt; Prognostics; Age Monitoring; Neurala Nätverk; Igbt; Prognostik; Övervakning av Ålder;

    Sammanfattning : In recent years, extensive research efforts have been dedicated to the field of prognostics and age-related degradation, with major focus on higher complexity devices. However, relatively little attention has been given to power devices, such as Insulated Bipolar Gate Transistors (IGBTs), despite their critical role in high power electronic applications. LÄS MER
