Multiband Passive Bistatic Radar Coherent Range and Doppler-Walk Compensation
(2015)The work simulates the performance of a coherent Passive Bistatic Radar multiband processing algorithm. The aim of the work is to present improved range resolution by coherently combine non-adjacent DVB-T channels, while ... -
SYSIPHE system: A state of the art airborne hyperspectral imaging system. Initial results from the first airborne campaign
(2014)SYSIPHE is an airborne hyperspectral imaging system, result of a cooperation between France (Onera and DGA) and Norway (NEO and FFI). It is a unique system by its spatial sampling -0.5m with a 500m swath at a ground height ... -
'Bomb-making for beginners': Inside an al-Qaida e-learning course
(2013)This study explores how terrorists utilize the Internet to learn bomb-making skills. Unlike previous studies, it does not focus on assessing the quality of online bomb recipes. Rather, it discusses the efforts being made ... -
A Comprehensive Simulation Methodology for Fluid-Structure Interaction of Offshore Wind Turbines
(2014)This paper gives an overview of a comprehensive simulation methodology for fluid-structure interaction (FSI) of offshore wind turbines that is being developed at the Applied Mathematics Department of SINTEF ICT. The ... -
Simulating CSF flow dynamics in the normal and chiari I subarachnoid space during rest and exertion
(2013)BACKGROUND AND PURPOSE: CSF fluid dynamics in healthy subjects and patients with Chiari I have been characterized during rest with phase-contrast MR imaging and CFD. CSF flow velocities and pressures in the nonresting state ... -
Effect of Tonsillar Herniation on Cyclic CSF Flow Studied with Computational Flow Analysis
(2011)BACKGROUND AND PURPOSE: The Chiari I malformation, characterized by tonsils extending below the foramen magnum, has increased CSF velocities compared with those in healthy subjects. Measuring the effect of tonsillar ... -
Coherent range and Doppler-walk compensation in PBR applications
(2014)The focus of PBR research has shifted from FM to also include DVB-T and DAB over the last years, and are facing the challenges of higher bandwidth, i.e. improved range resolution. While the FM based PBR systems primarily ... -
Comparison of terahertz technologies for detection and identification of explosives
(2014)We present results on the comparison of different THz technologies for the detection and identification of a variety of explosives from our laboratory tests that were carried out in the framework of NATO SET-193 “THz ... -
Federated single sign on in disconnected, intermittent and limited (DIL) networks
(2015)In a military setting resource exchange amongst coalition partners is of great importance. Using SAML2.0 in a Single Sign On scheme in a federated setting can be a solution to Web authentication of Web resources. The problem ... -
On the use of the HUGIN 1000 HUS Autonomous Underwater Vehicle for high resolution zooplankton measurements
(2010)This paper evaluates and tests the HUGIN 1000 HUS AUV as a carrier platform for the Laser Optical Plankton Counter (LOPC). The LOPC was mounted outside on top of the carrier platform, and the tests confirm that this concept ... -
Low-energy enhancement of nuclear γ strength and its impact on astrophysical reaction rates
(2014)An unexpected enhancement in the low-energy part of the γ-strength function for light and medium-mass nuclei has been discovered at the Oslo Cyclotron Laboratory. This enhancement could lead to an increase in the neutron-capture ... -
Temporal dynamics in microbial soil communities at anthrax carcass sites
(2017)Background Anthrax is a globally distributed disease affecting primarily herbivorous mammals. It is caused by the soil-dwelling and spore-forming bacterium Bacillus anthracis. The dormant B. anthracis spores become ... -
Third-generation femtosecond technology
(2014)Femtosecond pulse generation was pioneered four decades ago using mode-locked dye lasers, which dominated the field for the following 20 years. Dye lasers were then replaced with titanium-doped sapphire (Ti:Sa) lasers, ... -
Genetic distribution of 295 Bacillus cereus group members based on adk-screening in combination with MLST (Multilocus Sequence Typing) used for validating a primer targeting a chromosomal locus in B. anthracis
(2007)The genetic distribution of 295 Bacillus cereus group members has been investigated by using a modified Multilocus Sequence Typing method (MLST). By comparing the nucleic acid sequence of the adk gene fragment, isolates ... -
A Novel Method of Predicting Site DependentSpecific Rain Attentuation of Millimeter Radio Waves
(2003)There is a need for validation and improvement of propagation prediction methods for the safe design and operation of millimeter radio communication systems. At this frequency range, propagation related degradation is ... -
Comparison of Measurements with Prediction Methods for Propagation by diffraction at88 - 108 MHz
(2004)Three methods for predicting attenuation due to diffraction are tested against a large database of 115 614 measurement points, representing 115 614 different path profiles of 100-m horizontal resolution, and vertical root ... -
A comparison of rain attenuation and drop size distributionsmeasured in Chilbolton and Singapore
(2002)Attenuation of radio waves caused by precipitation, especially in the form of rain, is considered to be the limiting factor for new communication systems that will exploit the radio wave spectrum at frequencies higher than ... -
