Arctic Maritime Surveillance With Sentinel-1 Data Using a Norwegian Collaborative Ground Segment
(2017)The Sentinel-1A and Sentinel-1B C-band Synthetic Aperture Radar (SAR) satellites provide data for European Union's Copernicus program. Norway uses SAR satellites operationally to monitor Norway's maritime areas of interest. ... -
USRP based cognitive radar testbed
(2017)Cognitive radar is a relatively new field of research and the existence of low cost experimental testbeds is limited. This work will show the development of a low cost experimental testbed for experimental validation of ... -
LTE for Military Communication - Business Models and Vulnerabilities
(2017)This document outlines security issues concerning military use of LTE. It illustrates implications of different business models, and outlines vulnerabilities that decision makers should be aware of in order to protect the ... -
Uptake and effects of 2, 4, 6 - trinitrotoluene (TNT) in juvenile Atlantic salmon (Salmo salar)
(2017)Organ specific uptake and depuration, and biological effects in Atlantic salmon (Salmo salar) exposed to 2, 4, 6-trinitrotoluene (TNT) were studied. Two experiments were conducted, the first using radiolabeled TNT (14C-TNT, ... -
Avoidance responses of minke whales to 1?4 kHz naval sonar
(2017)Minke whales are difficult to study and little information exists regarding their responses to anthropogenic sound. This study pools data from behavioural response studies off California and Norway. Data are derived from ... -
Feasibility of a standard for full specification of spectral imager performance
(2017)The current state of the art of specifying spectral imagers falls short of what is needed. Commercial datasheets do not adequately reflect the performance of hyperspectral imagers offered as standard products. In particular, ... -
Military small arms fire in association with acute decrements in lung function
(2017)Objective After introduction of unleaded ammunition, Norwegian Armed Forces received reports of acute respiratory symptoms in soldiers after exposure to fumes from firing the standard weapon, HK416. The aim of the present ... -
Multichannel open tubular enzyme reactor online coupled with mass spectrometry for detecting ricin
(2017)For counterterrorism purposes, a selective nano liquid chromatography–mass spectrometry (nanoLC-MS) platform was developed for detecting the highly lethal protein ricin from castor bean extract. Manual sample preparation ... -
A 2.5-D Integrated Data Logger for Measuring Extreme Accelerations
(2017)A very compact and rugged 2.5-D integrated data logger has been built and tested. The data logger is capable of measuring accelerations exceeding 70 000 g. Microcontroller and flash memory as bare dies have been mounted ... -
The final destination: building test bed apps for DIL environments
(2015)Recent years have seen a massive growth in the everyday use of smartphones and tablet (here called smart mobile devices or SMDs) and a turn towards app based software to connect to cloud based services. This has had a huge ... -
Lack of behavioural responses of humpback whales (Megaptera novaeangliae) indicate limited effectiveness of sonar mitigation
(2017)Exposure to underwater sound can cause permanent hearing loss and other physiological effects in marine animals. To reduce this risk, naval sonars are sometimes gradually increased in intensity at the start of transmission ... -
Marine mammals and sonar: dose-response studies, the risk-disturbance hypothesis and the role of exposure context
(2017)Marine mammals may be negatively affected by anthropogenic noise. Behavioural response studies (BRS) aim to establish a relationship between noise exposure conditions (dose) from a potential stressor and associated behavioural ... -
Using a genetic algorithm to solve the troops-to-tasks problem in military operations planning
(2017)The troops-to-tasks analysis in military operational planning is the process where the military staff investigates who should do what, where, and when in the operation. In this paper, we describe a genetic algorithm for ... -
Projected area and drag coefficient of high velocity irregular fragments that rotate or tumble
(2017)3 degrees of freedom (DOF) exterior ballistic computer models are used in fragment studies to calculate individual trajectories of each fragment based on drag coefficient and the projected (presented) area in the direction ... -
Underwater Acoustic Communications: Long-Term Test of Turbo Equalization in Shallow Water
(2008)Acoustic telemetry sea trials lasting for three months with experiment periods of 7 h have been carried out, using a turbo receiver. The communication channel is shallow; the depth is approximately 10 m, and the range is ... -
Consequence assessment of indoor dispersion of sarin-A hypothetical scenario
(2010)The objective of this study is to provide a hypothetical scenario of indoor dispersion of the highly toxic nerve agent sarin in a large building, which can be used as a starting point for discussion, planning, training and ... -
Calculation of decomposition products from components of gunpowder by using ReaxFF reactive force field molecular dynamics and thermodynamic calculations of equilibrium composition
(2014)The major combustion products from munitions containing nitro-based propellants are water, carbon monoxide, carbon dioxide, hydrogen and nitrogen. In addition, compounds including hydrogen cyanide, ammonia, methane, nitrogen ... -
The Watermark benchmark for underwater acoustic modulation schemes
(2017)Watermark is a freely available benchmark for physical-layer schemes for underwater acoustic communications. It allows researchers to test and compare algorithms for the physical layer under realistic and reproducible ... -
CEP-stable few-cycle pulses with more than 190 μJ of energy at 100 kHz from a noncollinear optical parametric amplifier
(2017)Noncollinear optical parametric amplifiers (NOPAs) have become the leading technique for the amplification of carrier-envelope phase (CEP)-stable, few-cycle pulses at high repetition rate and high average power. In this ... -
Bitstream radar waveforms for generic single-chip radar
(2017)A Digital-to-Time converter (DTC) based on static CMOS multiplexers is presented, achieving a time resolution of 65 ps consuming 0.5 mW. The DTC relies on gate delay for programmability, ensuring robustness, linearity and ...
