Quad-Polarimetric SAR for Detection and Characterization of Icebergs
(Conference object; Konferansebidrag, 2016)This paper evaluates the performance of fully polarimetric SAR data in iceberg detection and characterization. The study aims to explore the potential of RADARSAT-2 SAR data to detect icebergs and growlers in Svalbard that have broken off from the glaciers nearby. To be able to detect iceberg/growlers in a SAR image, a significant contrast between iceberg and background clutter is required. The ... -
Non-gaussian clustering of SAR images for glacier change detection
(Journal article; Tidsskriftartikkel, 2010-12)Our aim is to use unsupervised, non-Gaussian clustering of Arctic glaciers for post-classification change detection. Firstly, we demonstrate the consistency of non-Gaussian clustering algorithms for Envisat ASAR images by characterizing the expected random error level for different SAR acquisition conditions (such as incidence angle). This allows us to determine whether an observed variation is ... -
Should Clinicians Split or Lump Psychiatric Symptoms? The Structure of Psychopathology in Two Large Pediatric Clinical Samples from England and Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-12-14)It has been suggested that the structure of psychiatric phenomena can be reduced to a few symptom dimensions. These proposals, mainly based on epidemiological samples, may not apply to clinical populations. We tested the structure of psychiatric symptoms across two pediatric clinical samples from England (N=8434) and Norway (N=5866). Confirmatory factor analyses of the parent-reported Strengths ... -

Semelfactives are bigger than degree achievements: The nanosyntax of Czech and Polish semelfactive and degree achievement verb stems
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-21)This paper argues that semelfactive and degree achievement verbs are morphosyntactically distinct, despite the fact that the morphemes they are made of are often syncretic even in languages with synthetic verb morphology like Czech or Polish. We use the mechanisms of Nanosyntax, a theory of the architecture of grammar in which the lexicon stores entire syntactic subtrees, to show that there is a ... -
