    Sammanfattning : Carbonaceous aerosol particles from combustion, such as diesel exhaust particles (DEP), harm human health and affect the Earth’s radiative system.Elemental carbon (EC) has been proposed to be used as a marker of DEP. LÄS MER

  5. 20. 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
