Norge - en motvillig europeer i nord
(2023-03-23)Denne artikkelen spør hva Norge, som et lite land utenfor EU, kan gjøre for å styrke sin posisjon som en viktig aktør i nordområdene. Russlands angrep på Ukraina og en tiltakende arbeidsdeling mellom EU og Nato for ... -
Norske fremmedkrigere i går og i dag

North European security after the Ukraine conflict
(2016)Russia’s illegal occupation and annexation of the Crimean peninsula in February–March 2014, and the country’s well-documented involvement in the separatist conflict in Eastern Ukraine, have led to a significant ... -
Northern bottlenose whales in a pristine environment respond strongly to close and distant navy sonar signals
(2019-03-20)Impact assessments for sonar operations typically use received sound levels to predict behavioural disturbance in marine mammals. However, there are indications that cetaceans may learn to associate exposures from distant ... -
A novel headspace sampler for field detection of chemical warfare agents and simulants connected to a commercial ion mobility detector
(2016)A rapid and simple sampling technique for use in conjunction with commercial ion mobility spectrometric detectors is described. The technique may be used for the detection of chemical warfare agents in the field. A plastic ... -
A Novel IoBT Security Assessment Framework: LoRaWAN Case Study
(2020)The Internet of Things (IoT) is interesting because this potentially disruptive technology can also be used as a low-cost approach to augment information in military systems. This makes following IoT trends important ... -
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 ... -
Nucleation and propagation of thermomagnetic avalanches in thin-film superconductors (Review Article)
(2018)Stability of the vortex matter—magnetic flux lines penetrating into the material—in type-II superconductor films is crucially important for their application. If some vortices get detached from pinning centres, the energy ... -
Numerical study of premixed gas explosion in a 1-m channel partly filled with 18650 cell-like cylinders with experiments
(2022-03-22)Abused and defective Li-ion cells can cause a catastrophic failure of a Li-ion battery (LIB), leading to severe fires and explosions. In recent years, several numerical and experimental studies have been conducted on the ... -
Numerical study of spatiotemporal distortions in noncollinear optical parametric chirped-pulse amplifiers
(2017)During amplification in a noncollinear optical parametric amplifier the spatial and temporal coordinates of the amplified field are inherently coupled. These couplings or distortions can limit the peak intensity, among ... -
O and Ne in an H-He Fast Solar Wind
(2011)We have studied the abundances and ion fractions of O and Ne in an H-He fast solar wind with emphasis on gravitational settling in the chromosphere and corona. We use a time-dependent numerical model that spans the mid- ... -
Obtaining spectral information from infrared scenarios using hyper-spectral cameras and cameras with spinning filter wheel
(2014)In the past decades the Norwegian Defence Research Establishment (FFI) has recorded and characterized infrared scenarios for several application purposes, such as infrared target and background modeling and simulation, ... -
OmpU as a biomarker for rapid discrimination between toxigenic and epidemic Vibrio cholerae O1/O139 and non-epidemic Vibrio cholerae in a modified MALDI-TOF MS assay
(2014)Background Cholera is an acute diarrheal disease caused by Vibrio cholerae. Outbreaks are caused by a genetically homogenous group of strains from serogroup O1 or O139 that are able to produce the cholera toxin. Rapid ... -
On synchronization in semelparous populations
(2005)Synchronization, i.e., convergence towards a dynamical state where the whole population is in one age class, is a characteristic feature of some population models with semelparity. We prove some rigorous results on this, ... -
On the Big Bang Cosmology as a Kinematic Event in Newtonian Cosmology Modified by Dark Energy
(2012)The concepts dark matter and dark energy are commonly used to explain the universe. The dark energy can be conceived as a property of vacuum or the ether. However, a quite different but also common approach is to modify ... -
On the Kinetics of Anaerobic Power
(2012)Background This study investigated two different mathematical models for the kinetics of anaerobic power. Model 1 assumes that the work power is linear with the work rate, while Model 2 assumes a linear relationship ... -
On the size of intermediate results in the federated processing of SPARQL BGPs
(2018)This paper is a foundational study in the semantics of federated query answering of SPARQL BGPs. Its specific concern is to explore how the size of intermediate results can be reduced without, from a logical point of view, ... -
On the study of ricochet and penetration in sand, water and gelatin by spheres, 7.62 mm APM2, and 25?mm projectiles
(2016)We examine the ricochet and penetration behavior in sand, water and gelatin by steel spheres, 7.62 mm APM2 and 25 mm projectiles. A threshold impact angle (critical angle) exists beyond which ricochet cannot occur. The ... -
On the Use of Computational Fluid Dynamics to Investigate Aerosol Dispersion in an Industrial Environment: A Case Study
(2012)Aerosol dispersion in the area surrounding an existing biological treatment facility is investigated using large-eddy simulation, with the objective to investigate the applicability of computational fluid dynamics to complex ...
