  1. 1. Ventilering av brännbara gaser vid batteribränder

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Fredrik Gahm; [2021]
    Nyckelord :Lithium-ion batteries; thermal runaway; energy storage; battery storage; ventilation; explosion; explosion hazard.; Litiumjonbatterier; termisk rusning; energilager; batterilager; ventilation; explosion; explosionsrisk.;

    Sammanfattning : The use of lithium-ion batteries is something that is becoming more common in today’s society. They are found in a variety of electronic equipment such as mobile phones, laptops and tools. Several incidents have been reported due to lithium-ion batteries ending up in a state called thermal runaway. LÄS MER

  3. 2. Improved Release Mechanisms for Aerospace Applications

    Kandidat-uppsats, Uppsala universitet/Tillämpad mekanik

    Författare :Baran Hamad; Markus Englund; [2021]
    Nyckelord :release mechanisms; hdrm; split spool initiator; reusable; smart materials; shape memory alloy; sma; pyrotechnic; non-explosive; spacecraft; nitinol; releasemekanismer; hdrm; fästelement; split spool-initierare; återanvändbar; minnesmetall; pyrotekniska; icke-explosiva; rymdfarkost; nitinol;

    Sammanfattning : Hold down release mechanisms (HDRMs) are used for tightly attaching segments of bodies together when it is desired to release them rapidly at some point. When transporting sensitive payloads on launch vehicles, the challenge arises of releasing the fastened segments of the spacecraft without risking damage to the costly equipment. LÄS MER

  4. 3. Identifying asset pricing bubbles: Testing for explosive behavior in the NASDAQ and STOXX 600 Europe Technology indices

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Tim Smits Van Oyen; Mathias Elmer; [2016]
    Nyckelord :Asset pricing bubble; explosive behavior; right-tailed ADF; forward recursive regression; Business and Economics;

    Sammanfattning : A forward recursive estimation method is used to examine stock market data on unit root against explosive behavior as an indication of financial exuberance. Through specific dividend-stock pricing modeling, the recursive implementation of a right-tailed ADF test allows for directly testing the price index series on explosive behavior and its corresponding dividend series on non-explosive behavior.

  5. 4. SECONDARY FLUIDS USED IN INDIRECT REFRIGERATION SYSTEMS IN SWEDEN

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Patrick Javier Salom Munoz; [2015]
    Nyckelord :Secondary fluids; ground source heat pumps; indirect refrigeration system; regulations; Swedish market;

    Sammanfattning : Interest in indirect (secondary) refrigeration systems has grown since the discovery of the negative effect of environmentally hazardous refrigerants and leakage problems from direct expansion systems. Among the positive effects of indirect systems are: decreased quantities of primary refrigerant, factory built units and confinement of refrigerant to the machine room. LÄS MER
