1. 11. Impartial Games and Recursive Functions

   Författare :Urban Larsson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Algorithmically undecidable; Beatty sequences; Blocking maneuver; Cellular automaton; Comply maneuver; Complementary sequences; Dictionary process; Dual game; Game complexity; Game convergence; Game reflexivity; Heap game; Impartial game; Invariant subtraction game; Move-size dynamic; Nim; P-equivalence; Rule 110; Splitting sequences; *-operator; Subtraction game; Take-away game; Turing complete; Wythoff Nim; Turing complete;

   Sammanfattning : Interest in 2-player impartial games often concerns the famous theory of Sprague-Grundy. In this thesis we study other aspects, bridging some gaps between combinatorial number theory, computer science and combinatorial games. LÄS MER

3. 12. Urban Area Information Extraction From Polarimetric SAR Data

   Författare :Deliang Xiang; Yifang Ban; Thuy Le Toan; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polarimetric SAR; Scattering Decomposition; Man-Made Target Detection; Edge Detection; Superpixel; Urban Classification; Polarimetrisk SAR; Spridningsnedbrytning; Upptäckt av artificiella objekt; Kantupptäckt; Superpixel; Urban klassificering; Geodesy and Geoinformatics; Geodesi och geoinformatik;

   Sammanfattning : Polarimetric Synthetic Aperture Radar (PolSAR) has been used for various remote sensing applications since more information could be obtained in multiple polarizations. The overall objective of this thesis is to investigate urban area information extraction from PolSAR data with the following specific objectives: (1) to exploit polarimetric scattering model-based decomposition methods for urban areas, (2) to investigate effective methods for man-made target detection, (3) to develop edge detection and superpixel generation methods, and (4) to investigate urban area classification and segmentation.

4. 13. Urban-Rural Relations in China : A Study of the Beijing-Tianjin-Hebei Metropolitan Region

   Författare :Yuheng Li; Hans Westlund; Göran Cars; Johan Klaesson; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Urban-rural linkages; Urban bias; Urban-rural interface; Beijing-Tianjin-Hebei Metropolitan Region; China; Human geography; economic geography; Kulturgeografi; ekonomisk geografi;

   Sammanfattning : Over three decades of rapid economic growth in China, beginning in 1978, has been accompanied by ever-enlarging urban-rural inequalities in terms of the various aspects of income, welfare, infrastructure, medical treatment, and education (amongst others). These two parts – the urban and the rural - have long been treated separately, without much consideration being given to their mutual linkages (relations). LÄS MER

5. 14. Towards Better Urban Spaces in Harmony with Microclimate: Urban design and planning regulations in hot dry Damascus, Syria

   Författare :Moohammed Wasim Yahia; Boende och bostadsutveckling; []
   Nyckelord :HUMANIORA; HUMANITIES; Architecture; Arid zones; Built environment; Climate; Climatic design; Damascus; Hot dry regions; Landscape elements; Microclimate; Planning regulations; Thermal comfort; Thermal indices; Urban climate; Urban design; Urban planning;

   Sammanfattning : This research is an attempt to develop further understanding of the relationship between microclimate, thermal comfort, urban design and outdoor space users in the hot dry city of Damascus. This is done by studying the impact of urban regulations on microclimate in different urban design patterns in Damascus. LÄS MER

7. 15. Lokalområdet som strategi för en hållbar stadsutveckling: fallstudier av tre danska exempel

   Författare :Lena Falkheden; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; participatory planning; urban design and planning; urban district; visual ecology; sustainable urban development; neighbourhood; ecological design; fair shares in environmental space; local area; urban ecology;

   Sammanfattning : During the 1990s the role of the city in a sustainability perspective has received increasing attention. Within the framework of the research field, sustainable urban development, this dissertation discusses issues concerning how environmental initiatives at the urban district level may be planned, designed and organised.
