  1. 1. Simulating cable fires in Fire Dynamics Simulator : Based on small scale testing in cone calorimeter

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Hugo Zacharoff; [2021]
    Nyckelord :Cable fires; FDS; cone calorimeter;

    Sammanfattning : In a society increasingly more influenced by technology and electricity, electrical and computer cables will play a more vital role in humans’ everyday life. With an increasing number of cables being introduced into society, the risk of fires caused by or involving cables will increase and become a more common danger to property and human lives. LÄS MER

  3. 2. Feldetektering i återgångkablar

    Kandidat-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Erik Asp; [2021]
    Nyckelord :Feldetektering;

    Sammanfattning : The purpose of ths report is to shed light on the problems surrounding error detection in returncables, specifically in connection with tunnels. In Sweden, among other things, has chosen to usea BT system with a suction transformer and a dedicated return conductor to reduce interferencesuch as occurs on telecommunications and signal cables along the track.

  5. 4. DEVELOPMENT OF RISK INFORMED METHODS FOR ESTIMATING RADIATION RELEASE FROM CABLE FIRES AT HIGH ENERGY PHYSICS FACILITIES

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Daniel Funk; [2020]
    Nyckelord :Fire Safety Engineering; CERN; Fire-induced Radiological release; particle accelerator; Fire Protection; Fire Risk Analysis; Technology and Engineering;

    Sammanfattning : CERN operates the Large Hadron Collider (LHC), the world’s largest and most powerful particle accelerator. The LHC was built to advance the state of knowledge in particle physics by increasing the energy of colliding particles to the TeV range. LÄS MER

  7. 5. Impact of Surrounding Objects on Inductive Wireless Power Transfer

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

    Författare :Brenda Odhiambo; [2019]
    Nyckelord :Wireless power transfer; inductive coupling; Qi Specification; effect of metals; Technology and Engineering;

    Sammanfattning : Many new models of smartphones and small electronic devices are using their wireless charging feature as a key selling point. This is due to the convenience of cable-free charging as well as not requiring multiple power adapters for charging different devices. LÄS MER
