BAKTRAK: Backtracking drifting objects using an iterative algorithm with a forward trajectory model
(2012)The task of determining the origin of a drifting object after it has been located is highly complex due to the uncertainties in drift properties and environmental forcing (wind, waves, and surface currents). Usually, the ... -
Capacities of metabotropic glutamate modulators in counteracting soman-induced seizures in rats
(2013)The mechanisms underlying insulin sensitivity and fat tissue distribution in chronic renal insufficiency remain unclear. Previous studies have shown the benefits of angiotensin II receptor blockers on moderately nourished ... -
Two medical therapies very effective shortly after high levels of soman poisoning in rats, but only one with universal utility
(2013)A treatment regimen consisting of HI-6, scopolamine, and physostigmine (termed the physostigmine regimen) has been based on the serendipitous discovery that it exerts powerful antidotal effects against high levels of soman ... -
The perirhinal cortex of rats: An intricate area for microinfusion of anticonvulsants against soman-induced seizures
(2013)Microinfusion of anticonvulsants into the perirhinal cortex through 1 guide cannula in each hemisphere only invades a small area of this seizure controlling site in rats exposed to soman. The purpose of the present study ... -
An ATR architecture for algorithm development and testing
(2013)A research platform with four cameras in the infrared and visible spectral domains is under development at the Norwegian Defence Research Establishment (FFI). The platform will be mounted on a high-speed jet aircraft and ... -
Using stereo SAR and InSAR by combining the COSMO-SkyMed and the TanDEM-X mission satellites for estimation of absolute height
(2013)The objective of this work is to estimate absolute height in synthetic aperture radar (SAR) interferograms. Since height in interferograms is relative, we use stereo SAR with several satellites to achieve absolute height ... -
Intracavity molecular spectroscopy in the mid-IR using ultra-broadband optical parametric oscillator
(2013)We have performed intracavity molecular spectroscopy of water vapor, isotopic carbon dioxide, methane, acetylene, carbon monoxide, formaldehyde and other gases using broadband mid-IR sync-pumped OPO sources (PPLN-based OPO ... -
Propagation and scattering effects in underwater acoustic communication channels
(2013)Systematic measurements were performed to characterize shallow-water acoustic propagation channels for applications in the field of underwater communications. The survey was conducted in northern Europe and covers the ... -
Three-dimensional multiple-source focalization in an uncertain ocean environment
(2013)This letter develops a Bayesian focalization approach for three-dimensional localization of an unknown number of sources in shallow water with uncertain environmental properties. The algorithm minimizes the Bayesian ... -
Improved estimation of oceanographic climatology using empirical orthogonal functions and clustering
(2013)Vertical profiles of temperature, salinity, and sound speed velocity are used in numerous applications where accurate vertical profiles are crucial. Conventional climatological representations of vertical oceanographic ... -
Effects of a 7-days military training exercise on inflammatory biomarkers, serum hepcidin, and iron status
(2013)Background Hepcidin, a peptide that is released into the blood in response to inflammation, prevents cellular iron export and results in declines in iron status. Elevated serum and urinary levels of hepcidin have been ... -
Reciprocity and the scattering matrix of waveguide modes
(2013)The implications of the Lorentz reciprocity theorem for a scatterer connected to waveguides with arbitrary modes, including degenerate, evanescent, and complex modes, are discussed. In general it turns out that a matrix ... -
Acoustic seabed classification using QTC IMPACT on single-beam echo sounder data from the Norwegian Channel, northern North Sea
(2013)Sediment mapping is important for understanding the physical processes, the impact of human activity, and the conditions for marine life on the seabed. For this purpose, the seabed classification tool QTC IMPACT analyses ... -
Wideband Interferometry in Synthetic Aperture Sonar
(2013)Synthetic aperture sonar (SAS) interferometry can provide very high resolution images and topographic maps of the seafloor over large swaths. Processing of interferometric data to retrieve reliable depth estimates of the ... -
Long-range tropospheric transport of uranium and plutonium weapons fallout from Semipalatinsk nuclear test site to Norway
(2013)A combination of state-of-the-art isotopic fingerprinting techniques and atmospheric transport modelling using real-time historical meteorological data has been used to demonstrate direct tropospheric transport of radioactive ... -
EFFECT OF COULOMB COLLISIONS ON THE GRAVITATIONAL SETTLING OF LOW AND HIGH FIRST IONIZATION POTENTIAL ELEMENTS
(2013)We model the effect of gravitational settling in the upper chromosphere on O, Fe, Si, and Ne, studying whether Coulomb collisions between ionized low First Ionization Potential (FIP) elements and protons is sufficient to ... -
Preparation and characterisation of epoxy/alumina polymer nanocomposites
(2013)The effect of adding nanosized alumina fillers of both fibre-like and spherical shapes to an epoxy polymer has been investigated. The alumina was dispersed in the epoxy hardener using two different sonication techniques. ... -
On-line solid phase extraction-liquid chromatography-mass spectrometry for trace determination of nerve agent degradation products in water samples
(2013)Three primary nerve agent degradation products (ethyl-, isopropyl- and pinacolyl methylphosphonic acid) have been determined in water samples using on-line solid phase extraction-liquid chromatography and mass spectrometry ... -
Serial Ricinine Levels in Serum and Urine after Ricin Intoxication
(2013)Ricinine is an alkaloid present in the castor bean plant (Ricinus communis) that can be used as a biomarker for ricin poisoning. Serial ricinine levels are reported in the serum and urine of a patient suffering from ... -
A Graphical User Interface for Multivariable Analysis of Silicon Solar Cells Using Scripted PC1D Simulations
(2013)PC1D is an open source computer program for simulation of crystalline semiconductor devices, and is the most commonly used simulation software in the solar cell community today. In this work we present a modified version ...
