  1. 1. Drying of Multicomponent Liquid Films

    University dissertation from Stockholm : Kemiteknik

    Author : Fabio Luna; KTH.; [2004]
    Keywords : ternary mixture; falling film; diffusion equation; gas-phase control; liquid-phase control; selectivity; stability analysis; polymeric solution; evaporation; azeotrope; batch drying; continuous drying;

    Abstract : The convective drying of thin layers of multicomponentliquid mixtures into an inert gas, and the influence ofdifferent process controlling mechanisms on drying selectivityis studied. Drying experiments under gas-phase-controlledconditions are performed by low intensity evaporation, fromfree liquid surfaces, of ternary mixtures without non-volatilesolutes. READ MORE

  2. 2. Ultrafast opto-optical control of extreme ultraviolet light pulses

    University dissertation from Atomic Physics, Department of Physics, Lund University

    Author : Samuel Bengtsson; Lunds universitet.; Lund University.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; extreme ultraviolet; controlled emission; Free induction; time-dependent spectroscopy; noble; High order harmonic generation; phase-control;

    Abstract : Extreme ultraviolet (XUV) light is a valuable frequency range for ultrafast optics experiments. The short wavelength is a requirement for ultrashort pulses, which are widely used to characterize fast dynamics. Additionally, the high photon energy enables quantum control of high frequency transitions in atoms. READ MORE

  3. 3. Micro- and Millimeter Wave CMOS Beamforming Receivers

    University dissertation from Atomic Physics, Department of Physics, Lund University

    Author : Andreas Axholt; Lunds universitet.; Lund University.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; beamforming; CMOS; front-end; microwave; millimeter wave; phase-locked loop; phased-array;

    Abstract : Popular Abstract in Swedish Det tillgängliga frekvensutrymmet i trådlösa kommunikationssystem, så som trådlösa datornätverk, är mycket begränsat. Detta tillsammans med den ökande trafikmängden skapar problem. Nya möjligheter finns dock i och med att det finns stora mängder bandbredd som är licensfri för användning. READ MORE

  4. 4. Microwave CMOS Beamforming Transmitters

    University dissertation from Tryckeriet i E-huset, Lunds universitet

    Author : Johan Wernehag; Lunds universitet.; Lund University.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Beamforming transmitter; CMOS; frequency doubling power amplifier; polyphase filter; phase shifting;

    Abstract : The increase of the consumer electronics market the last couple of decades has been one of the main drivers of IC process technology development. The majority of the ICs are used in digital applications, and for these CMOS is the choice of technology. The urge to squeeze more transistors on to a given area has led to shrinking feature sizes.

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; optik; acoustics; optics; Electromagnetism; Ionization Dynamics; Electron Wave Packet Interferometry; Electron Wave Packet Control; Pulse Characterization; High-Order Harmonics; Attosecond Pulse Trains; Atom- och molekylärfysik; Atomic and molecular physics; akustik; Elektromagnetism;

    Abstract : Popular Abstract in Swedish Vill man ta en bild av något som rör sig mycket snabbt, krävs det att man använder en kort exponeringstid. Om kamerans slutare är öppen under för lång tid, hinner det man vill fotografera röra sig under tiden filmen exponeras, med resultatet att bilden blir suddig. READ MORE
