  1. 1. Mode switch for component-based multi-mode systems

    Författare :Hang Yin; Hans Hansson; Tomas Bures; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; component-based; multi-mode; mode switch; Computer Science; datavetenskap;

    Sammanfattning : Component-based software engineering is becoming a prominent solution to the development of complex embedded systems. Since it allows a system to be built by reusable and independently developed components, component-based development substantially facilitates the development of a complex embedded system and allows its complexity to be better managed.

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

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

    Sammanfattning : 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. LÄS MER

  4. 3. High Frequency (MHz) Planar Transformers for Next Generation Switch Mode Power Supplies

    Författare :Radhika Ambatipudi; Kent Bertilsson; Bengt Oelmann; Jesus Doval Gandoy; Hans-Peter Nee; Torbjörn Thiringer; Göran Thungström; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Planar Magnetics; DC-DC Converters; Switch Mode Power Supplies; MHz Frequency Region;

    Sammanfattning : Increasing the power density of power electronic converters while reducing or maintaining the same cost, offers a higher potential to meet the current trend inrelation to various power electronic applications. High power density converters can be achieved by increasing the switching frequency, due to which the bulkiest parts, such as transformer, inductors and the capacitor's size in the convertercircuit can be drastically reduced.

  5. 4. Affective Forecasting in Travel Mode Choice

    Författare :Tore Pedersen; Margareta Friman; Erik Hölzl; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Affective Forecasting; Satisfaction; Focusing Illusion; Defocusing; Public Transport; Travel Mode Choice; Psykologi; Psychology;

    Sammanfattning : The general aim of this thesis was to investigate affective forecasting in the context of public transport. Paper I, Study 1 revealed that non-users of public transport were less satisfied with the services than users. LÄS MER

  7. 5. Advanced Transmitter Architectures Based on Switch Mode Power Amplifiers

    Författare :MUSTAFA ÖZEN; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combiner; SMPA; Bandwidth; class-E; outphasing; energy efficiency;

    Sammanfattning : Nowadays the main driving parameters for the research in radio transmitters in wireless infrastructure are energy efficiency, frequency agility, and integration.This thesis presents new solutions at the device waveform-, circuit-, and transmitter level which exploit the inherent high efficiency potential of switch-mode power amplifiers (SMPAs) for realization of energy efficient, wide-band, highly integrated transmitters for wireless communication applications.
