Hvordan Putin ble overbevist om å gå til krig
(2023-05-02)Russlands angrep på Ukraina 24. februar 2022 sjokkerte store deler av verden. Putins misnøye med utviklingen i Ukraina og landets tilnærming til Vesten var velkjent, men de fleste trodde lenge at han ikke ville gå til ... -
Hvorfor så ambivalent? USAs politikk overfor EUs forsvarsambisjoner
(2021-01-19)Artikkelen diskuterer forholdet mellom den europeiske integrasjonsprosessen og det atlantiske samarbeidet under USAs ledelse. Problemstillingen artikkelen besvarer er hvilke tilnærminger Trump-administrasjonen har hatt til ... -
A Hybrid Architecture Framework for Simulations in a Service-Oriented Environment
(2017)Service orientation, and more recently, the notions of cloud technology that service orientation enable, are designed to accommodate the need for flexible enterprise business processes. Through standardized interfaces, a ... -
A hybrid recorded-synthetic sonar data set for validation of ASW classification algorithms
(2015)Modern anti-submarine warfare sonars are often designed with narrow beamwidths and wide frequency bandwidths in order to maximize spatial resolution and sonar performance. A known issue for high-resolution sonars in littoral ... -
Hyperosmolar sodium chloride is toxic to cultured neurons and causes reduction of glucose metabolism and ATP levels, an increase in glutamate uptake, and a reduction in cytosolic calcium
(2016)Elevation of serum sodium, hypernatremia, which may occur during dehydration or treatment with sodium chloride, may cause brain dysfunction and damage, but toxic mechanisms are poorly understood. We found that exposure to ... -
HYPSO-1 CubeSat: First Images and In-Orbit Characterization
(2023-01-28)The HYPSO-1 satellite, a 6U CubeSat carrying a hyperspectral imager, was launched on 13 January 2022, with the Goal of imaging ocean color in support of marine research. This article describes the development and current ... -
Identification and quantification of lichenysin – a possible source of food poisoning
(2015)Lichenysin produced by 53 different Bacillus licheniformis strains has been structurally examined with a qualitative liquid chromatography-tandem mass spectrometry (LC-MS/MS) method using quadrupole-time-of-flight mass ... -
Identification of airborne bacteria by 16S rDNA sequencing, MALDI-TOF MS and the MIDI microbial identification system
(2015)The aim of this study was to collect and identify airborne bacteria in Norway, Sweden and Finland and to compare three different technologies for identifying collected airborne bacterial isolates: the “gold standard” method ... -
Identification of mixed substances using a random forest regressor to classify THz absorbance spectra
(2018)We report on the development and application of a random forest regressor that not only identifies but also estimates the relative concentrations of substances (one explosive and two simulants), both in one-substance and ... -
Image-aided inertial navigation for an Octocopter
(2018)A typical unmanned aerial system combines an Inertial Navigation System (INS) and a Global Navigation Satellite System (GNSS) for navigation. When the GNSS signal is unavailable, the INS errors grow over time and eventually ... -
Imaging ground sensor system OPAK
(2003-09-18)Architecture and technology of imaging intrusion detection sensor OPAK are presented. Applications and desired features for IDS and UGS are compared. Started developments of OPAK towards an unattended ground sensor system ... -
Imaging radar for navigation and surveillance on an autonomous unmanned ground vehicle capable of detecting obstacles obscured by vegetation
(2019-09-16)The Norwegian Defence Research Establishment (FFI), has developed a multi purpose radar demonstrator for Intelligence, Surveillance and Reconnaissance (ISR) on the Off-road Light Autonomous Vehicle (OLAV) platform. The ... -
The Importance of Significant Others in Preventing Extremism: The Philosophy and Practice of the Swedish Tolerance Project
(2020)This article concerns a specific educational programme to reduce recruitment to racist and extreme organizations in Sweden. The programme is called the Tolerance Project, and it functions as an elective course offered to ... -
Improved active sonar tactical support by through-the-sensor estimation of acoustic seabed properties
(2014)Accurate environmental information is required for obtaining confident sonar performance predictions. This environmental information is, however, often unreliable or unavailable. To support antisubmarine warfare (ASW) ... -
Improved conceptualising of hybrid interference below the threshold of armed conflict
(2023-06-08)European policymakers have identified the need to understand influence operations on social media, cyber-attacks or hidden economic investments – activities that can be characterised as hybrid threats or hybrid warfare. ... -
Improved correction methods for measuring altitude by Radar and Barometer
(2018)Geometric altitude of air targets may be found from radar or barometric measurement. However, radar rays are affected by changes in refractive index gradients which result in non-normal bending of rays. Similarly, precision ... -
Improved discretisation and linearisation of active tension in strongly coupled cardiac electro-mechanics simulations
(2012)Mathematical models of cardiac electro-mechanics typically consist of three tightly coupled parts: systems of ordinary differential equations describing electro-chemical reactions and cross-bridge dynamics in the muscle ... -
Improved estimation of oceanographic climatology using empirical orthogonal functions and clustering
(2013)Vertical profiles of temperature, salinity, and sound speed velocity are used in numerous applications where accurate vertical profiles are crucial. Conventional climatological representations of vertical oceanographic ... -
Improved Passivation Effect Due to Controlled Smoothing of the CdTe-HgCdTe Interface Gradient by Thermal Annealing
(2019-07-11)HgCdTe films grown by liquid phase epitaxy were passivated with CdTe grown by molecular beam epitaxy. A series of annealing tests with different temperatures and durations were then carried out in order to reach a two-fold ...
