   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.

5. 44. Re-evaluation of methods to identify individuals with increased risk of caries

   Författare :Anna Senneby; Malmö högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; caries; risk assessment; diagnostic accuracy; methodology; acid tolerance; reliability; agreement;

   Sammanfattning : The overall aim of this thesis was to evaluate methods used to identify individuals with increased risk of coronal caries lesion development. The specific aims were to:•evaluate the accuracy of different methods used to identify individuals with increased risk of developing dental coronal caries lesions (study I)•design and pilot a novel classification system for the assessment of caries lesion progression in bitewing radiography and to report rater agreement of the system (study II)•assess intra-individual differences in biofilm acid-tolerance between different tooth surfaces and inter-individual variation as well as stability of acid tolerance over time (study III)•assess diagnostic accuracy of two established methods and a candidate method to identify adolescents with increased risk of dental coronal caries lesion development (study IV).
