  2. 1. Urban shades of green : Current patterns and future prospects of nature conservation in urban landscapes

    Author : Sara Borgström; Regina Lindborg; Sara Cousins; Thomas Elmqvist; Christer Nilsson; Stockholms universitet; []
    Keywords : urbanisation; nature conservation; urban planning; urban systems; nature reserves; Sweden; NATURAL SCIENCES; NATURVETENSKAP; naturresurshushållning; Natural Resources Management;

    Abstract : Urban nature provides local ecosystem services such as absorption of air pollutants, reduction of noise, and provision of places for recreation, and is therefore crucial to urban sustainable development. Nature conservation in cities is also part of the global effort to halt biodiversity decline. READ MORE

  4. 2. INDOOR NOISE FROM URBAN RAILBOUND TRANSPORT

    Author : SIGMUND OLAFSEN; Teknisk akustik; []
    Keywords : Tramway noise; acoustics; Indoor noise;

    Abstract : Methods for determination of indoor noise and vibrations from urban rail bound transport are presented in this work. Both measurement methods and empirical prediction methods are described. The data and results are taken from field measurements of noise and vibrations from the trams and metro trains of Oslo.

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

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

    Abstract : 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. READ MORE

  6. 4. Stellar Surface Structures and the Astrometric Serach for Exoplnaets

    Author : Urban Eriksson; Lindegren Lennart; Kristianstad University; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astrometry; astronomy;

    Abstract : Measuring stellar parallax, position and proper motion is the task of astrometry. With the development of new and much more accurate equipment, different noise sources are likely to affect the very precise measurements made with future instruments. READ MORE
