Choice of approaches in developing novel medical countermeasures for nerve agent poisoning
(2014)During the establishment of a research branch, all relevant matters encountered will be of interest to study. After having acquired a body of basal knowledge, it becomes possible to derive ideas or hypotheses for further ... -
Thirty years after its foundation – where is al-Qaida going?
(2017)This article presents a framework for understanding al-Qaida, based on a new reading of its thirty-year history. Al-Qaida today is commonly labelled a ‘global insurgency’ or ‘global franchise.’ However, these labels are ... -
How to assess good candidate molecules for self-activated optical power limiting
(2018)Reverse saturable absorbers have shown great potential to attenuate laser radiation. Good candidate molecules and various particles have successfully been incorporated into different glass matrices, enabling the creation ... -
Metrics and provider-based results for completeness and temporal resolution of satellite-based AIS services
(2018)Collecting AIS messages from ships by satellites allows for maritime situational awareness, and a wide range of commercial applications, at global and regional scales. This work provides methods and indicators for evaluation ... -
Exact 3D scattering solutions for spherical symmetric scatterers
(2018)In this paper, exact solutions to the problem of acoustic scattering by elastic spherical symmetric scatterers are developed. The scatterer may consist of an arbitrary number of fluid and solid layers, and scattering with ... -
Isogeometric Analysis of Acoustic Scattering using Infinite Elements
(2018)Isogeometric analysis (IGA) has proven to be an improvement on the classical finite element method (FEM) in several fields, including structural mechanics and fluid dynamics. In this paper, the performance of IGA coupled ... -
Stochastic space interval as a link between quantum randomness and macroscopic randomness?
(2017)For many stochastic phenomena, we observe statistical distributions that have fat-tails and high-peaks compared to the Gaussian distribution. In this paper, we will explain how observable statistical distributions in the ... -
Evaluation of camouflage pattern performance of textiles by human observers and CAMAELEON
(2017)Military textiles with camouflage pattern are an important part of the protection measures for soldiers. Military operational environments differ a lot depending on climate and vegetation. This requires very different ... -
Scenario modelling with morphological analysis
(2017)Scenarios can serve as points of reference in the future for decisions that we have to make today. Morphological analysis provides a structured method for ensuring consistency and relevance in scenario development. This ... -
Mathematical modelling of the oxygen uptake kinetics during whole-body endurance exercise and recovery
(2017)In this study, we elucidate four different mathematical models of the kinetics of oxygen uptake during whole-body endurance exercise at different intensities and throughout the subsequent recovery periods. We employ the ... -
DETOUR trials: The mission and its results
(2017)In this paper DMPAR Evaluation Trials for Operationally Upgraded Radar (DETOUR) and their results for a selected scenario are described. The DETOUR trials were conducted by the SET-195 research task group (RTG) under an ... -
A Reactive Collision Avoidance Algorithm for Vehicles withUnderactuated Dynamics
(2017)This paper presents a reactive collision avoidance algorithm, which avoids both static and moving obstacles by keeping a constant avoidance angle between the vehicle velocity vector and the obstacle. In particular, we ... -
Robust eye-safe pulsed fiber laser source for 3D ladar applications
(2017)We present a pulsed all-fiber Er/Yb-doped master oscillator power amplifier at 1.55 μm wavelength. In a simple two-stage amplifier design, the source delivers 140 μJ pulses at 25 kHz and 50 kHz pulse repetition frequency, ... -
Country survey: military expenditure and defence policy in Norway 1970?2013
(2017)This article examines military expenditure and defence policy in Norway from 1970 to 2013. Until 1990 Norwegian military expenditure remained between 2.5 and 3.0 per cent of Gross Domestic Product (GDP). Despite constant ... -
DVB-T Passive Radar Dual Polarization Measurements in the Presence of Strong Direct Signal Interference
(2017)A dual-polarization passive bistatic radar is used to evaluate the potential benefit of cross-polarized measurements for the suppression of strong direct signal interference in the DVB-T band. The linear array antenna ... -
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 ...
