  2. 6. Meeting-places of Transformation : Urban Identity, Spatial Representations and Local Politics in St Petersburg, Russia

    Author : Thomas Borén; Bo Lenntorp; Thomas Lundén; Jussi Jauhiainen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Time-space; lifeworld; Hägerstrand; Habermas; Lotman; participant observation; post-Soviet transformation; time-geography; cultural geography; cultural semiotics; urban studies; everyday life; Soviet cartography; local self-government; Ligovo; Uritsk; Krasnosel skii raion.; Other earth sciences; Övrig geovetenskap;

    Abstract : This study develops a model for understanding spatial change and the construction of space as a meeting-place, and then employs it in order to show an otherwise little-known picture of (sub-)urban Russia and its transformation from Soviet times to today. The model is based on time-geographic ideas of time-space as a limited resource in which forces of various kinds struggle for access and form space in interaction with each other. READ MORE

  5. 8. Exploring Strategies for the Combination of Multiple Space-geodetic Techniques

    Author : Periklis Diamantidis; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Space Geodesy; GNSS; Combination on the Observation Level; EOP; Reference Systems; VLBI; Local Ties;

    Abstract : Space-geodetic techniques are based on signal acquisition from extraterrestrial radio sources that can be used to infer geodetic positioning and define Earth-fixed and inertial reference systems. These techniques, which include Very Long Baseline Interferometry (VLBI) and Global Navigation Satellite Systems (GNSS) among others, exhibit different strengths and weaknesses in recovering parameters of interest.

  6. 9. Global Savannah Phenology : Integrating Earth Observation, Ecosystem Modeling, and PhenoCams

    Author : Niklas Boke-Olén; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Savannahs are land areas where grass and trees co-exists to create a landscape that is neither a grassland nor a forest. It is estimated that savannahs cover approximately one sixth of the global land surface. They also play an important role in the global carbon cycle due to their total size. READ MORE

  7. 10. Analyzing Vegetation Trends with Sensor Data from Earth Observation Satellites

    Author : Sadegh Jamali; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Change detection; Satellite sensor data; Time series analysis; Vegetation dynamics; Vegetation index;

    Abstract : Abstract This thesis aims to advance the analysis of nonlinear trends in time series of vegetation data from Earth observation satellite sensors. This is accomplished by developing fast, efficient methods suitable for large volumes of data. READ MORE
