    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-temperature district heating; active thermal micro-grid; substation operation; performance assessment; distributed heat resources; chauffage urbain basse température; micro-réseaux de chaleur urbains actifs; fonctionnement de la sous-station; évaluation de la performance; sources de chaleur distribuées; lågtemperatur fjärrvärme; aktiv fjärrvärmemikronät; fjärrvärmecentral operation; prestationsbedömning; distribuerada värmekällor; Energy Technology; Energiteknik;

    Sammanfattning : Energy use in the urban environment is vital for the proper functioning of our society, and in particular, comfort heating –or cooling– is a central element of our energy system often taken for granted. Within this context, district energy systems and especially, district heating (DH) systems must evolve to adapt to the upcoming decades-long transition towards a sustainable energy system. LÄS MER

  4. 18. Measurements and Models of One-Way Transit Time in IP Routers

    Författare :Doru Constantinescu; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Traffic measurements; Traffic modeling; Delay performance;

    Sammanfattning : The main goals of this thesis are towards an understanding of the delay process in best-effort Internet for both non-congested and congested networks. A novel measurement system is reported for delay measurements in IP routers, which follows specifications of the IETF RFC 2679. LÄS MER

  5. 19. Network Modelling for Evaluation of Mechanical Properties of Cellulose Fibre Fluff

    Författare :Susanne Heyden; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydraulic engineering; Civil engineering; fracture; fibres; computer simulation; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Sammanfattning : A network mechanics model for cellulose fibre fluff is proposed. 2D and 3D versions of the model have been implemented and the influence of various micro-level parameters on the global mechanical performance has been determined by means of computer simulations. LÄS MER

  7. 20. High-resolution mapping and spatial variability of soil organic carbon storage in permafrost environments

    Författare :Matthias Benjamin Siewert; Gustaf Hugelius; Peter Kuhry; Iain Hartley; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbon; soil organic carbon; permafrost; soil; land cover classification; digital soil mapping; machine-learning; ecosystem; mapping; landscape studies; Siberia; Arctic; Physical Geography; naturgeografi;

    Sammanfattning : Large amounts of carbon are stored in soils of the northern circumpolar permafrost region. High-resolution mapping of this soil organic carbon (SOC) is important to better understand and predict local to global scale carbon dynamics. LÄS MER
