  1. 1. Modelling of Dislocation Bias in FCC Materials

    Författare :Zhongwen Chang; Pär Olsson; Christophe Domain; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Irradiation induced void swelling is problematic for the application of austenitic steels under high dose irradiation. In this thesis, the swelling is characterized by dislocation bias. The dislocation bias is obtained using the finite element method, accounting for fcc copper and nickel under electron irradiation.

  3. 2. Frequency Domain Linearized Navier-Stokes Equations Methods for Low Mach Number Internal Aeroacoustics

    Författare :Axel Kierkegaard; Gunill Efraimsson; Christophe Schram; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Akustik;

    Sammanfattning : Traffic is a major source of environmental noise in modern day's society. As a result, the development of new vehicles are subject to heavy governmental legislations. The major noise sources on common road vehicles are engine noise, transmission noise, tire noise and, at high speeds, wind noise. LÄS MER

  4. 3. CFD Modelling of Hydrogen Rich Biomass Syngas Combustion

    Författare :Nikolaos Papafilippou; Rikard Gebart; Kentaro Umeki; Muhammad Aqib Chishty; Christophe Duwig; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; RANS; LES; FGM; Turbulent Combustion; Numerical Combustion; Swirling Flows; Gas Turbines; Biomass Syngas; Hydrogen; Energiteknik; Energy Engineering;

    Sammanfattning : The loss of biodiversity, due to pollution and global warming, is more important and relevant now than it has ever been. Man made climate warming has its roots in the huge amount of CH4 and CO2 emissions, which have increased by 47% and 156% respectively since 1750. LÄS MER

  5. 4. Exotic Ribosomal Enzymology

    Författare :Josefine Liljeruhm; Anthony C. Forster; Christophe Danelon; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; rRNA modification; Methyltransferase; RlmM; RlmJ; D-amino acid; Unnatural amino acid; Chromoprotein; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Sammanfattning : This thesis clarifies intriguing enzymology of the ribosome, the multiRNA/multiprotein complex that catalyzes protein synthesis (translation). The large ribosomal RNAs (23S and 16S rRNAs in E. coli) are post-transcriptionally modified by many specific modification enzymes, yet the functions of the modifications remain enigmatic. LÄS MER

  7. 5. Phase-changing flows: numerical methods and fully resolved simulations

    Författare :Nicolo Scapin; Luca Brandt; Christophe Duwig; Outi Tammisola; Matthias Ihme; KTH; []
    Nyckelord :Phase change; interface-resolved simulations; compressibility; evaporating droplets; evaporation-driven thermal convection.; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Flows with evaporation and boiling are abundant in different contexts, such as geophysics, the biomedical sectors, and industrial applications. Spray combustion, boiling bubble flows, oceanic sprays, formation and evolution of clouds, spreading of infectious diseases are all relevant examples where a deeper understanding of phase-changing flows is of great importance.
