  1. 1. Urban-Rural Relations in China : A Study of the Beijing-Tianjin-Hebei Metropolitan Region

    Författare :Yuheng Li; Hans Westlund; Göran Cars; Johan Klaesson; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Urban-rural linkages; Urban bias; Urban-rural interface; Beijing-Tianjin-Hebei Metropolitan Region; China; Human geography; economic geography; Kulturgeografi; ekonomisk geografi;

    Sammanfattning : Over three decades of rapid economic growth in China, beginning in 1978, has been accompanied by ever-enlarging urban-rural inequalities in terms of the various aspects of income, welfare, infrastructure, medical treatment, and education (amongst others). These two parts – the urban and the rural - have long been treated separately, without much consideration being given to their mutual linkages (relations). LÄS MER

  3. 2. Closed-loop Identification : Methods, Theory, and Applications

    Författare :Urban Forssell; Lennart Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : System identification deals with constructing mathematical models of dynamical systems from measured data. Such models have important applications in many technical and nontechnical areas, such as diagnosis, simulation, prediction, and control. LÄS MER

  4. 3. Properties and Usage of Closed-loop Identification Methods

    Författare :Urban Forssell; Lennart Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : System identification deals with the construction of mathematical models of dynamical systems using measured data. Closed-loop identification is what results when performing the identification experiment under output feedback, that is, in closed loop. LÄS MER

    Sammanfattning : It is well known that thin coatings can provide increased lifetime and reduced energy consumption for tools and components. During use, e.g. LÄS MER

  7. 5. Kinetic Energy Storage and Magnetic Bearings : for Vehicular Applications

    Författare :Johan Abrahamsson; Hans Bernhoff; Urban Lundin; Richard Magdalena Stephan; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flywheel; magnetic bearing; energy storage; electric vehicle; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : One of the main challenges in order to make electric cars competitive with gas-powered cars is in the improvement of the electric power system. Although many of the energy sources currently used in electric vehicles have sufficientlyhigh specific energy, their applicability is limited due to low specific power. LÄS MER
