Federated Identity Management in a Tactical Multi-Domain Network
(2011)Identity Management maintains information regarding actors of an Information System, like users, equipment and services. One important service is to disseminate and validate credentials for the purpose of authentication ... -
Solar Wind from Coronal Funnels and Transition Region Lyalpha
(2005)Using a newly developed gyrotropic solar wind model that extends continuously from the mid-chromosphere to 1 AU and that accounts for radiative losses in the transition region, we have studied the difference between the ... -
Statistics-based filtering for low signal-to-noise ratios, applied to rocket plume imaging
(2017)Extracting information from low signal to noise ratio images poses significant challenges. Noise makes extracting spatial features difficult, in particular if extraction of both large, smooth features at the same time as ... -
Planning and conducting crisis management exercises for decision-making: the do’s and don’ts
(2017)Organizations exercise to strengthen their crisis management capability, to identify possible improvements to plans, and to develop necessary skills. Taking part in exercises is one way leaders can test their decision-making ... -
Enhancement in Light Emission From Hg-Cd-Te Due to Surface Patterning
(2011)Enhancement of light emission from HgCdTe due to surface patterning has been studied by means of photoluminescence (PL) spectroscopy. A triangular pattern of circular holes was etched into the CdTe layer grown on top of ... -
Critical thickness of MBE-grown Ga1-xInxSb (x < 0.2) on GaSb
(2009)Several Ga1−xInxSb layers, capped with 1 μm of GaSb, were grown on GaSb(0 0 1) substrates by molecular beam epitaxy in a Varian Gen II Modular system using either the conventional sample growth position with substrate ... -
Russia's Northern Fleet and the Oil Industry-Rivals or Partners? Petroleum, Security, and Civil-Military Relations in the Post-Cold War European Arctic
(2009)Described as one of the world's most promising new energy provinces, the European Arctic is no longer primarily seen as a military playground. Russia's approach to the region is increasingly governed by national economic ... -
When Security Speech Acts Misfire: Russia and the Elektron Incident
(2009)In October 2005, the Russian trawler Elektron refused to be subjected to arrest when caught by the Norwegian coast guard fishing illegally in the Fisheries Protection Zone off the Svalbard archipelago. With two Norwegian ... -
The ECOMA 2007 campaign: rocket observations and numerical modelling of aerosol particle charging and plasma depletion in a PMSE/NLC layer
(2009)The ECOMA series of rocket payloads use a set of aerosol particle, plasma, and optical instruments to study the properties of aerosol particles and their interaction with the ambient plasma environment in the polar mesopause ... -
Spin scan tomographic imager
(2015)A novel imaging device based on tomographic reconstruction is presented. The imager is based on rotating an image of the scene onto a linear detector array, and then reconstructing a 2-dimensional image from the detector ... -
Experimental tomographic scanning (TOSCA) imagers
(2014)The tomographic scanner (TOSCA) detects signals using line detectors scanning a scene at regularly distributed angles. These line scan signals are then processed to reconstruct 2-dimensional images. In the simplest form, ... -
Study of the seasonal ozone variations at European high latitudes
(2011)The geographic area at high latitudes beyond the polar circle is characterized with long darkness during the winter (polar night) and with a long summertime insolation (polar day). Consequentially, the polar vortex is ... -
Deletion of the γ-aminobutyric acid transporter 2 (GAT2 and SLC6A13) gene in mice leads to changes in liver and brain taurine contents
(2012)The GABA transporters (GAT1, GAT2, GAT3, and BGT1) have mostly been discussed in relation to their potential roles in controlling the action of transmitter GABA in the nervous system. We have generated the first mice lacking ... -
The social context of individual foraging behaviour in long-finned pilot whales (Globicephala melas)
(2014)Long-finned pilot whales (Globicephala melas) are highly social cetaceans that live in matrilineal groups and acquire their prey during deep foraging dives. We tagged individual pilot whales to record their diving behaviour. ... -
Improved active sonar tactical support by through-the-sensor estimation of acoustic seabed properties
(2014)Accurate environmental information is required for obtaining confident sonar performance predictions. This environmental information is, however, often unreliable or unavailable. To support antisubmarine warfare (ASW) ... -
Health effects after firing small arms comparing leaded and unleaded ammunition
(2014)A number of Norwegian soldiers have reported health problems after live-fire training using the HK416 rifle. The objective of this study was to characterize gaseous and particulate emissions from three different types of ... -
A logical characterisation of SPARQL federation
(2014)The paper provides a logical characterisation of distributed processing of SPARQL queries. The principal notion analysed is that of a distribution scheme; a pair consisting of an evaluation rule and a distribution function. ... -
The modus operandi of jihadi terrorists in Europe
(2014)This article provides the most thorough overview yet of how jihadis have plotted terrorist attacks in Europe. Drawing on a database of 122 incidents, we review trends in weapon types, attack types and target types in the ...
