Time Series Investigation of Land Subsidence Using a Weighted Least Squares Adjustment Based on Image Mode Interferometric Data
(Conference object; Konferansebidrag, 2010)
This study presents the weighted least squares method based on Interferometric Synthetic Aperture Radar (InSAR) images to retrieve spatial-temporal evolution of land subsidence in Mashhad Valley, northeast Iran. Using the analysis of a few interferograms covering the 2003-2005 period, Motagh et al (GJI 2006) presented a preliminary analysis of the subsidence in this area. Here we extend this study ...
Studies of DC biasing of internal ring on plasma rotation and transport in a toroidal geometry
(Conference object; Konferansebidrag, 2004-10)
We report results from experiments performed to study how a DC bias with respect to
the plasma potential is affecting the plasma states in the toroidal geometry of the
Blaamann device in Tromso. In the experiments discussed here, a ring with smaller
diameter than the limiter was centered inside the bulk of the plasma and its bias varied
with respect to the plasma potential.
In the electron ...
An Advanced Non-Gaussian Feature Space Method for POL-SAR Image Segmentation
(Conference object; Konferansebidrag, 2013)
This work extends upon our simple feature-based multichannel SAR segmentation method to incorporate highly desirable statistical properties into a computationally simple
approach. The desirable properties include Markov random field contextual smoothing and goodness-of-fit testing to automatically obtain the significant number of classes. To achieve this we need to find an explicit class model to ...

A Simple and Extendable Segmentation Method for Multi-Polarisation SAR Images
(Conference object; Konferansebidrag, 2013)
This work presents a simple feature-based multi-channel
SAR segmentation method that produces good, smooth,
fast and robust results for image segmentation and interpretation.
A basic set of six features produce good class
distinction for general applications, and the method is
easily extendable with new features and for multi-source
data fusion. Optional steps of sub-sampling and Markov
Random ...
