  3. 7. Numerical Optimization of a propeller in a given wake and behind a ship

    Författare :Kaijia Han; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; propeller geometry; pressure fluctuation; correction; full scale; efficiency; RANS; cavitation; grid density; verification; delivered power; optimization; Hamburg test case; iteration number;

    Sammanfattning : The work presented in this thesis includes two stages in a research project at the Rolls-Royce University Technology Center (UTC) at Chalmers Technology University. The objective of the project is to develop an optimization technique for ship/propeller interaction. LÄS MER

  4. 8. 3D nano-tomography using coherent X-rays

    Författare :Maik Kahnt; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ptychography; Tomography; Phase reconstruction; X-ray microscopy;

    Sammanfattning : X-rays allow to non-destructively investigate biological, chemical or physical processes at the nano-scale. Their high penetration depth in matter allows to investigate samples even inside sample environments, which would be difficult with complementary methods such as transmission electron microscopy (TEM).

  5. 9. Ultrafast resonant magnetic scattering at the European XFEL

    Författare :Nanna Zhou Hagström; Stefano Bonetti; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; XFEL; ultrafast magnetism; holography; SAXS; fysik; Physics;

    Sammanfattning : Magnetic materials are of interest in a wide range of nanotechnologies such as for data storage, memory, logic, and sensing applications. Today, there is a strong desire to manipulate magnetism at timescales below the picosecond. There is therefore a high motivation in studying ultrafast magnetism at the nanoscale. LÄS MER

  7. 10. FPGA-based Instrumentation for Advanced Physics Experiments

    Författare :Attila Hidvégi; Samuel Silverstein; Martin Grossmann; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Instrumentation; Data acquisition; clock distribution; trigger; FPGA; PCB; LHC; ATLAS; XFEL; fysik; Physics;

    Sammanfattning : Modern physical experiments often demand advanced instrumentation based on advances in  technology. This work describes four instrumentation physics projects that are based on modern, high-capacity Field-Programmable Gate Arrays, making use of their versatility, programmability, high bandwidth communication interfaces and signal processing capabilities.
