    Sammanfattning : This thesis presents HELIOS, an in-house laboratory for time-resolved pump-probe spectroscopy with extreme-ultraviolet (XUV) probe radiation. A wide span of pump wavelengths can be generated using commercial laser equipment while XUV probe radiation is generated via a high harmonic generation process in a noble gas delivering probe photons with energies between 20 eV and 72 eV.

  3. 2. Lokala fjärrvärmesystem

    Författare :Lena C. Olsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; district heating; radiator circuit; low radiator flow; local network; pressure separator; jet pump;

    Sammanfattning : The thesis Local district heating systems deals with a new concept for district heating. The district heating system is arranged as one main system and a number of local systems. The production plants and the main distribution lines belong to the main system. LÄS MER

  4. 3. An Intense Attosecond Light Source - Towards Extreme Ultraviolet Pump-Probe Experiments

    Författare :Filippo Campi; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Attosecond; Femtosecond; Ultrashort; Ultrafast; High-order Harmonic Generation; pump probe; XUV; Fysicumarkivet A:2017:Campi;

    Sammanfattning : This thesis presents important steps towards performing high-intensity attosecond pump-probe experiments at the Lund high-intensity extreme ultraviolet (XUV) beamline, which followed two complementary paths: maximization of the XUV intensity available in the interaction region with a gas target, and providing attosecond temporal resolution.To maximize the energy of the XUV pulses generated via high-order harmonicgeneration (HHG), the macroscopic response of atoms to the driving infrared field was optimized.

  5. 4. Computational modelling of blood flow in medical assist devices

    Författare :Francesco Fiusco; Lisa Prahl Wittberg; Lars Mikael Broman; Anders Dahlkild; David Ku; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computational fluid dynamics; haemodynamics; platelet activation; thrombogenicity; haemolysis; extracorporeal membrane oxygenation; sensitivity; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Extracorporeal membrane oxygenation (ECMO) is a life-saving support treat-ment in case of pulmonary and/or cardiac failure. An artificial extracorporealcircuit is used to offload the function of lungs and/or heart. LÄS MER

  7. 5. Assessment of cavitation erosion risk based on single-fluid simulation of cavitating flows

    Författare :Mohammad Hossein Arabnejad Khanouki; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Cavitation erosion is material loss due to the repetitive collapse of cavities near the surface. This phenomenon is one of the limiting factors in the design of high-performance marine propulsors as it restricts their reliability and increases their operational cost. LÄS MER
