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 ... -
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 ... -
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 ... -
Operationalizing Protection of Civilians in NATO Operations
(2015)Though NATO and other military forces increasingly recognize protection of civilians as a key objective in their operations, implementation remains challenging. To effectively protect, the military force must understand ... -
Optical limiting properties and z-scan measurements of carbon disulfide at 2.05 μm wavelength
(2016)Nonlinear and optical limiting properties of carbon disulfide (CS 2 ) are characterized at 2.05 μm wavelength using a 𝑄 -switched Ho:YLF laser with high pulse energy. The nonlinear refractive index of CS 2 is measured ... -
Optical limiting properties of carbon disulfide at 2.05μm wavelength
(2016)Several types of infrared sensors are based on sensitive focal plane arrays. In such sensors, the intensity will typically increase by a factor ~107 at the focal plane, compared to the intensity of the incoming radiation. ...
