  1. 1. Hybrid observers for systems with intrinsic pulse-modulated feedback

    Författare :Diana Yamalova; Alexander Medvedev; Xiaoming Hu; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid systems; impulsive systems; biomedical systems; Goodwin s oscillator; observers; time-delay; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : Dynamical processes resulting from the interaction of continuous and discrete dynamics are often encountered in living organisms. Time evolutions of such processes constitute continuous variables that are subject to instant changes at discrete points of time. LÄS MER

    Sammanfattning : Filtering and reconstruction of signals play a fundamental role in modern signal processing, telecommunications, and control theory and are used in numerous applications. The feedback principle is an important concept in control theory. LÄS MER

  4. 4. Fund Managers as Cultured Observers

    Författare :Johan Henningsson; Ulf Johanson; Roland Almqvist; Matti Skoog; Guy Ahonen; Mälardalens högskola; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; System theory; network theory; intellectual capital; capital market; SRI funds; working environment; Business and economics; Ekonomi; Industriell ekonomi och organisation;

    Sammanfattning : During the last few decades, Intellectual Capital (IC) has been recognized as an important resource in firms. In order to improve IC reporting, a number of guidelines have been initiated in Europe and in Japan. The capital market has been one important target group for these initiatives. LÄS MER
