  2. 1. Introducing Mode Switch in Component-Based Software Development

    Author : Hang Yin; Hans Hansson; Paul Pettersson; Thomas Nolte; Carlo Ghezzi; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mode switch; multi-mode; component-based; Computer Science; datavetenskap;

    Abstract : Self-adaptivity, characterized by the ability to dynamically adjust behavior at runtime, is a growing trend in the evolution of modern embedded systems. While self-adaptive systems tend to be flexible and autonomous, self-adaptivity may inevitably complicate software design, test and analysis. READ MORE

  4. 2. Power Quality Disturbances and Protective Relays

    Author : Fan Wang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; overcurrent relays; component switching; frequency deviation; power system disturbance; protection algorithms; power quality; digital protective relays; impedance relays;

    Abstract : This thesis combines knowledge from two areas: power quality and power system protection. Power quality concerns the effect of voltage disturbances on end-user equipment and of current disturbances on network components. Power system protection concerns the detection of faults in the system from measured voltages and currents. READ MORE

  5. 3. Switching Kinetics and Charge Transport in Organic Ferroelectrics

    Author : Tim Cornelissen; Martijn Kemerink; Mats Fahlman; Kamal Asadi; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic Electronics; Ferroelectrics; Organic Ferroelectrics;

    Abstract : The continued digitalization of our society means that more and more things are getting connected electronically. Since currently used inorganic electronics are not well suited for these new applications because of costs and environmental issues, organic electronics can play an important role here. READ MORE

  6. 4. Fibre Bragg Grating Components for Filtering, Switching and Lasing

    Author : Zhangwei Yu; Lars Thylén; Pierre-Yves Fonjallaz; Lin Zhang; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fibre Bragg grating; photosensitivity; apodization; chirp; phase-shift; microwave optical filtering; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : Fibre Bragg gratings (FBGs) are key components for a vast number of applications in optical communication systems, microwave photonics systems, and optical sensors, etc. The main topic of this thesis is fibre Bragg grating fabrication and applications in direct microwave optical filtering, high speed switching and switchable dual-wavelength fibre lasers.

  7. 5. Bacterial virulence and adaptation mediated by two-component system signalling

    Author : Henrik Tomenius; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Virulence; atomic force microscopy; biofilm; adaptation; two-component system; signal transduction; gene regulation; phosphorylation; BarA; UvrY;

    Abstract : One of the most fundamental ways of signal perception and propagation is mediated by the bacterial two-component system (TCS). These types of systems mediate bacterial adaptation that may cause disease in a host due to expression of virulence factors. READ MORE
