Convex Variational Methods on Graphs for Multiclass Segmentation of High-Dimensional Data and Point Clouds
(2017)Graph-based variational methods have recently shown to be highly competitive for various classification problems of high-dimensional data, but are inherently difficult to handle from an optimization perspective. This ... -
Augmented Lagrangian method for an Euler's elastica based segmentation model that promotes convex contours
(2017)In this paper, we propose an image segmentation model where an L1 variant of the Euler's elastica energy is used as boundary regularization. An interesting feature of this model lies in its preference for convex segmentation ... -
Combination of stereo SAR and InSAR for DEM generation using TanDEM-X spotlight data
(2017)The objective of this work is to generate accurate digital elevation models (DEMs) from synthetic aperture radar (SAR) interferograms using the spotlight and staring spotlight modes during the TanDEM-X (TDX) science phase. ... -
Sparse Phase Estimation and Processing of Independent Coherent Processing Intervals
(2017)Radars employing electronically steering arrays are capable of instantaneously altering the direction of the beam along with other parameters. This flexibility offers great opportunities to a radar as it may e.g. divide ... -
Compressed Sensing with Interleaving Slow-Time Pulses and Hybrid Sparse Image Reconstruction
(2017)This paper explores a type of hybrid sparse reconstruction technique for modern multifunction task scheduling radars and on following range-Doppler plots. A compressed sensing (CS) framework is devised to emit and then ... -
The effect of contrast in camouflage patterns on detectability by human observers and CAMAELEON
(2015)Evaluation of signature properties of military equipment is very important. It is crucial to apply the proper method out of many possible approaches, based on amongst others ranking by probability of detection, detection ... -
High-resolution Spaceborne SAR Processing Using the Decomposed Transfer Function
(2017)In this paper a new analytic decomposed transfer function (DTF) for spaceborne SAR (Synthetic Aperture Radar) processing is calculated using the stationary phase approximation and Taylor’s series expansion. The DTF copes ... -
A Study of the Detonation Properties, Propellant Impulses, Impact Sensitivities and Synthesis of Nitrated ANTA and NTO Derivatives
(2016)Nitrated derivatives of 5-amino-3-nitro-1,2,4-triazole (ANTA) and 3-nitro-1,2,4-triazol-5-one (NTO) were theoretically characterized with respect to their performance as high explosives and rocket propellants. The detonation ... -
Mitotic catastrophe in BC3H1 cells following yessotoxin exposure
(2017)The marine toxin yessotoxin (YTX) can cause various cytotoxic effects depending on cell type and cell line. It is well known to trigger distinct mechanisms for programmed cell death which may overlap or cross-talk. The ... -
Smokeless GAP-RDX Composite Rocket Propellants Containing Diaminodinitroethylene (FOX-7)
(2017)Composite rocket propellants prepared from nitramine fillers (RDX or HMX), glycidyl azide polymer (GAP) binder and energetic plasticizers are potential substitutes for smokeless double-base propellants in some rocket motors. ... -
Jihadi Terrorism in Europe: The IS-Effect
(2016)The article examines the extent to which Islamic State (IS) has affected jihadi terrorism in Europe. We look at the scope of attack activity, perpetrators and their networks, modus operandi and funding. For all the talk ... -
Plasma Cytokine Profiles in Long-Term Strenuous Exercise
(2016)The open window theory indicates altered immunity 3 to 72 hours after exercise. The J-curve describes the risk of illness in response to exercise. The aim of this study was to examine the secretion of proinflammatory and ... -
Isocyanate-Free and Dual Curing of Smokeless Composite Rocket Propellants
(2013)Traditional composite rocket propellants are cured by treatment of hydroxyl-terminated prepolymers with polyfunctional aliphatic isocyanates. For development of smokeless composite propellants containing nitramines and/or ... -
Distribution and mobility of lead (Pb), antimony (Sb) and copper (Cu) from ammunition residues on shooting ranges for small arms located on mires
(2017)An environmental survey was performed on shooting ranges for small arms located on minerotrophic mires. The highest mean concentrations of Pb (13 g/kg), Cu (5.2 g/kg), Zn (1.1 g/kg), and Sb (0.83 g/kg) in the top soil were ... -
Large-eddy simulation of dense gas dispersion over a simplified urban area
(2017)Dispersion of neutral and dense gas over a simplified urban area, comprising four cubes, has been investigated by the means of large-eddy simulations (LES). The results have been compared to wind tunnel experiments and ... -
Multiple-array passive acoustic source localization in shallow water
(2017)This paper considers concurrent matched-field processing of data from multiple, spatially-separated acoustic arrays with application to towed-source data received on two bottom-moored horizontal line arrays from the SWellEx-96 ... -
Jihadistenes program i Europa
(2016)Trusselen fra jihadisme i Europa har aldri vært høyere enn den er nå. I følge en ny studie fra Forsvarets forskningsinstitutt (FFI) har det i 2015 og 2016 vært en betydelig økning i planlagte og utførte terrorangrep med ... -
