  1. 1. Investigation of Ice Nucleating Particles (INPs) in southern Sweden - With a special focus on their origin, possible connection to meteorological parameters and aerosol properties

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Malin Forsmalm; [2023-06-21]
    Nyckelord :INPs; DFA; LUCS;

    Sammanfattning : This study investigates if there is a seasonal variability of ice nucleating particle (INP) concentrations. There is also a focus in seeing if there are correlations between meteorological parameters and aerosol properties and the measured INP concentrations. LÄS MER

    Sammanfattning : Massive multiple input multiple output - MIMO systems are a reality and modern communication systems rely upon this technology to cope with the increasing need for capacity and network usage. Antenna arrays are at the heart of the of the massive-MIMO system and are the enabling technology. LÄS MER

  4. 3. Effekter av packning av finfilter i fyllningsdammar

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

    Författare :Anton Jonsson; [2023]
    Nyckelord :Fyllnadsdamm; Finfilter; Packningsgrad;

    Sammanfattning : There are over 10 000 dams in Sweden of various types and sizes. Most of the larger dams were built around 1950-1970 when the Swedish hydropower was expanded. Since then, the knowledge of engineering dam structures has increased and there are new guidelines for how a dam should be built. LÄS MER

  5. 4. Exploring Particulate Filtration during Thermal Runaway in Lithium-Ion Battery Packs

    Master-uppsats, KTH/Kemiteknik

    Författare :Amanda Halvarsson; [2023]
    Nyckelord :battery pack; particles; thermal runaway; filtration; batteripack; partiklar; termisk rusning; filtrering;

    Sammanfattning : Med övergången till elektrifiering inom transport uppstår nya utmaningar när det gäller batterisystem som placeras i elfordon. Det finns för närvarande en möjlighet att minska riskerna med toxiciteten hos partiklar som sprutas ut med de gaser som bildas under termisk rusning i litiumjonbattericeller som är placerade i batterisystem.

  7. 5. Cavity Beam Position Monitors State of the Art and Design Studies in the Context of the ILC Project

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola

    Författare :Laura Karina Pedraza Motavita; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The aim of this master thesis project is the study and evaluation of the design of cavity beam position monitors (BPM) for the International Linear Collider (ILC) project. The state-of-the-art of BPMs is investigated to determine the most appropriate existing BPM design for the requirements of the ILC. LÄS MER
