  1. 26. Local spatio-temporal image features for motion interpretation

    Författare :Ivan Laptev; KTH; []
    Nyckelord :computer vision; motion; recognition; scale-space;

    Sammanfattning : Visual motion carries information about the dynamics of ascene. Automatic interpretation of this information isimportant when designing computer systems forvisualnavigation, surveillance, human-computer interaction, browsingof video databases and other growing applications.

  3. 27. Spatial and temporal metrology of intense attosecond pulses

    Författare :Helene Coudert-Alteirac; Atomfysik; []
    Nyckelord :Ultrafast optics; High-order harmonic generation; Filamentation; Attosecond; Femtosecond; Extreme ultraviolet; Wavefront measurement; Optical metrology; XUV optics; interferometry; Pump-probe; Fysicumarkivet A:2018:Coudert-Alteirac;

    Sammanfattning : Attosecond pulses are short enough to capture the electronic dynamics in atoms and molecules. The work presented in this thesis deals with the generation and optimization of attosecond extreme-ultraviolet (XUV) pulses. LÄS MER

  4. 28. Temporal Studies of Molecular Processes using Resonant Spectroscopy : Femtosecond experiments with synchrotron radiation and pulsed lasers

    Författare :Ingela Hjelte; Dennis Lindle; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; fysik; Physics;

    Sammanfattning : The physical and chemical properties of matter are to a high degree determined by the electronic structure. One of the most powerful experimental techniques to study the electronic structure is electron spectroscopy. LÄS MER

  5. 29. Plant community assembly and biodiversity: a spatio-temporal perspective

    Författare :Oliver Purschke; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phylogenetic diversity; null model; life-history traits; land use history; landscape fragmentation; dispersal; functional diversity; semi-natural grasslands;

    Sammanfattning : Biodiversity, the variety of life at all organisational levels from genes to ecosystems, affects ecosystem processes and therefore the goods and services ecosystems provide. More research is needed to provide new insights into biodiversity changes and the processes that drive these changes, in order to formulate effective policy and conservation measures to stop the ongoing biodiversity loss.

  7. 30. A Study of Some Temporal Properties of the Human Visual Evoked Potential, and Their Relation to Binocular Function

    Författare :Björn Johansson; Peter Jakobsson; Anders Sjöström; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; VEP Visual Evoked Potential ; contrast sensitivity; binocularity; latency; Fourier analysis; strabismus; amblyopia; Ophtalmology; Oftalmologi;

    Sammanfattning : As disturbed binocular functions in small children may lead to severe amblyopia it is of interest to detect it as early as possible. Most tests for binocular functions, however, demand active cooperation and may be unreliable in children up to 4-5 years of age. LÄS MER
