  4. 2. QCM-D with focus on variations in oscillation amplitude

    Author : Malin Edvardsson; Chalmers tekniska högskola; []
    Keywords : shear oscillation; actuator; Quartz crystal microbalance; amplitude; streptavidin; lipid vesicles; biosensor; colloidal particles; size distribution; QCM-D; protein binding; DNA hybridization; dual harmonic; lipid bilayer formation;

    Abstract : The QCM-D (quartz crystal microbalance with dissipation monitoring) technique is an increasingly popular tool in studies of molecular interactions at interfaces, e.g. binding/unbinding reactions at surfaces, studies of thin film properties, and conformational changes. READ MORE

  5. 3. Power System Oscillations - Detection, Estimation and Control

    Author : Morten Hemmingsson; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; oscillation; power system; damping; power swing; distance protection; detection; estimation; real-time; reactive co-variation; control; Electrical engineering; load modulation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : The topic of this thesis is the electro-mechanical oscillations which to some extent always are present in a power system. The demand of electric power is ever increasing. At the same time, the tolerance of disruptions in the power supply is decreasing. READ MORE

  6. 4. On the Load Distribution and Design of a Chain Drive

    Author : Ingvar Troedsson; Maskinelement; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tension force; tensioner; oscillation; chain drive; vibration; load distribution; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Abstract : Three methods are presented to calculate the load distribution in a chain drive containing two sprockets and one chain. The rollers, which are in contact with the sprockets, can move along the tooth flanks and their positions are given by force equilibrium. READ MORE

  7. 5. Laser-Driven Particle Acceleration - Improving Performance Through Smart Target Design

    Author : Matthias Burza; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; wakefield; ultra-relativistic; ultra-intense; TNSA; Terawatt; sheath; proton; polarimetry; plasma mirror; plasma; Petawatt; particle; oscillation; Normarski; micromachining; LWFA; laser; interferometry; electron; contrast; acceleration; bubble; Fysicumarkivet A:2012:Burza;

    Abstract : Laser-driven particle acceleration makes use of sub-picosecond, pulsed, high-power laser systems, capable of producing intensities ~10^{19} W/cm^2 at the laser focus to form plasmas, and use ultra-relativistic and nonlinear dynamics to produce quasistatic acceleration fields. This allows electrons to be accelerated to ~100 MeV over sub-centimetre distances, while protons may be accelerated to the ~10 MeV regime. READ MORE
