  1. 11. Jordbruksmark i förändring. Drivkrafter bakom och förutsättningar för offentlig styrning i Sverige och Norge

    Författare :Elin Slätmo; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sustainable; land use; agriculture; landscape; change; driving forces; time-geography; actor-structure; context; scale; governance; spatial planning;

    Sammanfattning : With a focus on agricultural land use change, the overriding aim of this thesis is to contribute to the development of a more sustainable use and management of resources. A core requirement for doing so is to develop deeper knowledge of the ways we use resources and change land uses today. LÄS MER

  3. 12. Electron Wave Packet Dynamics on the Attosecond Time Scale

    Författare :Kathrin Klünder; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photoionization; Single attosecond pulses; Attosecond pulse trains; Electron wave packet; Electron dynamics; Interferometry; Photoemission time delay; Fysicumarkivet A:2012:Klünder; Stark spectroscopy;

    Sammanfattning : One objective of attosecond science is to study electron dynamics in atoms and molecular systems on their natural time scale. This can be done using attosecond light pulses. LÄS MER

  4. 13. On large scale real time music distribution : security, reliability and heterogeneity

    Författare :Roland Parviainen; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distribuerade datorsystem; Mobile and Pervasive Computing;

    Sammanfattning : This thesis presents a system for real-time large scale distributed music distribution, such as radio on the Internet. The existing technologies do not enable the full potential that broadcast media on the Internet can give, such as a very large number of interactive receivers. LÄS MER

  5. 14. Short-Term Traffic Prediction in Large-Scale Urban Networks

    Författare :Matej Cebecauer; Erik Jenelius; Wilco Burghout; Balázs Kulcsár; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; travel time prediction; short-term travel time prediction; traffic prediction; clustering; partitioning; spatio-temporal partitioning; large-scale prediction; PPCA; 3D speed map; Transportvetenskap; Transport Science;

    Sammanfattning : City-wide travel time prediction in real-time is an important enabler for efficient use of the road network. It can be used in traveler information to enable more efficient routing of individual vehicles as well as decision support for traffic management applications such as directed information campaigns or incident management.

  7. 15. Multiple Time Scales and Longitudinal Measurements in Event History Analysis

    Författare :Danardono; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistics; Cox regression; multiple events; proportiona hazards; random effects; survival analysis; time-dependent covariates; time origin; Statistik; Statistics; Statistik; Statistics; statistik;

    Sammanfattning : A general time-to-event data analysis known as event history analysis is considered. The focus is on the analysis of time-to-event data using Cox's regression model when the time to the event may be measured from different origins giving several observable time scales and when longitudinal measurements are involved.
