  1. 1. Propagation of Nuclear Data Uncertainties for Reactor Physics Parameters in Fluorine-19-based Molten Salt Reactors

    Master-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Sigfrid Stjärnholm; [2023]
    Nyckelord :;

    Sammanfattning : It could be argued that a renaissance is taking place for the global interest in nuclear power - especially for the development of the next generation of reactor systems that aim at solving the problems with contemporary energy production with nuclear technology. One such proposed concept for Gen IV nuclear power is a Molten Salt Reactor (MSR), in which the nuclear fuel is in solution of a salt - often based on fluorine or chlorine. LÄS MER

  3. 2. The effect of furniture on room acoustic parameters and its dependence on the sound absorbing properties of the ceiling

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Huong Nguyen; [2023]
    Nyckelord :Room acoustics; furniture; Sabine s formula; SEA model; sound absorption; sound scattering; reverberation time; speech clarity; sound strength; Technology and Engineering;

    Sammanfattning : In ordinary public rooms such as classrooms and offices, the base line of acoustical treatment is an absorbent suspended ceiling. Due to the non-uniform distribution of the absorptive ceiling material, the scattering as well as the absorption properties of furniture will have a significant effect on room acoustic parameters such as reverberation time, speech clarity and sound strength.

  4. 3. Analysis and Measurement of Key Performance Indicators for MIMO Antennas

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Ossian Kynman; [2023]
    Nyckelord :MIMO; Diversity Gain; Capacity; Correlation; Fading;

    Sammanfattning : Multiple-in multiple-out (MIMO) is a wireless communication technique where antenna arrays, at the receiver and transmitter, utilize signal multipath propagation to increase data throughput capacity. The unique benefits MIMO provides have over the last 20 years led to the steady increase in usage in both Wi-Fi and mobile networks. LÄS MER

  5. 4. Optimising microfluidic preparation of lipid sponge phase nanoparticles for biomolecule encapsulation

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Owais Khalil; [2023]
    Nyckelord :Sponge phase; lipid nanoparticles; microfluidics; SAXS; cryo-TEM; DLS; chemical engineering; Chemistry;

    Sammanfattning : Drug delivery with lipid nanoparticles, especially sponge phase lipid nanoparticles (LNP), has been well studied because of its ability for drug encapsulation and transferring the drug through the cell membrane. The sponge phase LNP formulation could be affected by the molecular structure of the lipid, the temperature, pH, dilution, the buffer, and the addition of a stabiliser. LÄS MER

  7. 5. Back analysis of rock mass properties in the regional fault zone under Lake Mälaren

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Jiaqi Liu; [2022]
    Nyckelord :Rock mass property; back analysis; tunnel deformation; optimization algorithm; numerical analysis; Bergmassans egenskaper; bakåtanalys; tunnleldeformation; optimeringingsalgoritm; numeriska analyser.;

    Sammanfattning : The properties of the surrounding rock mass in underground projects have significant impacts on the design and construction. However, it is quite challenging to evaluate rock mass properties due to the great uncertainties of the geological conditions. LÄS MER
