Mass analysis of charged aerosol particles in NLC and PMSE during the ECOMA/MASS campaign
(2009)
MASS (Mesospheric Aerosol Sampling Spectrometer) is a multichannel mass spectrometer for charged aerosol particles, which was flown from the Andoya Rocket Range, Norway, through NLC and PMSE on 3 August 2007 and through ...
First in situ measurement of the vertical distribution of ice volume in a mesospheric ice cloud during the ECOMA/MASS rocket-campaign
(2009)
We present in situ observations of mesospheric ice particles with a new particle detector which combines a classical Faraday cup with the active photoionization of particles and subsequent detection of photoelectrons. Our ...
Spaceborne Bistatic SAR Processing Using the EETF4 Algorithm
(2009)
In this letter, the fourth-order extended exact transfer function (EETF4) is adapted for spaceborne bistatic synthetic aperture radar (SAR) processing. The problems with high squint and large bistatic Doppler centroid ...
Real-time anomaly detection in hyperspectral images using multivariate normal mixture models and GPU processing
(2009)
Hyperspectral imaging, which records a detailed spectrum of light arriving in each pixel, has many potential uses in remote sensing as well as other application areas. Practical applications will typically require real-time ...
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 ...
Deteksjon av eksplosivrester i felt ved hjelp av hyperspektral avbildning
(2009)
Der er kjent at det i Forsvarets skytefelt ligger rester av eksplosiver, noe som hovedsakelig skyldes ufullstendig detonasjon av ammunisjon. Disse restene er vanskelige å finne, men er ansett å være et miljøproblem blant ...
Effects of 4-methylimidazole on cerebral glutamate decarboxylase activity and specific GABA receptor binding in mice
(2009)
4-Methylimidazole (4MeI) is a tremorogenic and convulsive agent of concern both in human and veterinary toxicology. The in vitro effects of 4MeI (5 μM–20 mM) on cerebral glutamate decarboxylase (GAD) activity and (in ...
A simple Ladar simulator based on ray tracing
(2009)
In the study of ladar image processing, it is useful to have a method for producing synthetic data. This report presents a simple ladar simulator implemented in Matlab, which produces synthetic ladar images by simulating ...
