Meta-heuristics for improved RF emitter localization
(2017)Locating Radio Frequency (RF) emitters can be done with a number of methods, but cheap and widely available sensors make the Power Difference of Arrival (PDOA) technique a prominent choice. Predicting the location of an ... -
Russian defense spending after 2010: the interplay of personal, domestic, and foreign policy interests
(2017)Since 2010, Russia’s defense spending has seen an average annual real growth of 10%, causing a profound shift in the composition of government expenditure. This article examines the formal and informal processes through ... -
Accumulation of lead (Pb) in brown trout (Salmo trutta) from a lake downstream a former shooting range
(2017)An environmental survey was performed in Lake Kyrtjønn, a small lake within an abandoned shooting range in the south of Norway. In Lake Kyrtjønn the total water concentrations of Pb (14 µg/L), Cu (6.1 µg/L) and Sb (1.3 ... -
Cerebrospinal Fluid Phosphate in Delirium after Hip Fracture
(2017)Aims: Phosphate is essential for neuronal activity. We aimed to investigate whether delirium is associated with altered phosphate concentrations in cerebrospinal fluid (CSF) and serum. Methods: Seventy-seven patients with ... -
Distribution and mobility of lead (Pb), antimony (Sb) and copper (Cu) from ammunition residues on shooting ranges for small arms located on mires
(2017)An environmental survey was performed on shooting ranges for small arms located on minerotrophic mires. The highest mean concentrations of Pb (13 g/kg), Cu (5.2 g/kg), Zn (1.1 g/kg), and Sb (0.83 g/kg) in the top soil were ... -
Changes in intestinal microbiota composition and metabolism coincide with increased intestinal permeability in young adults under prolonged physiologic stress
(2017)The magnitude, temporal dynamics, and physiological effects of intestinal microbiome responses to physiological stress are poorly characterized. This study used a systems biology approach and a multiple-stressor military ... -
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 ... -
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 ... -
Modeling the behavior of a hierarchy of command agents with context-based reasoning
(2017)Context-based reasoning is a paradigm for modeling agent behavior that is based on the idea that humans only use a small portion of their knowledge at any given time. It was specially designed to represent human tactical ... -
High-resolution Spaceborne SAR Processing Using the Decomposed Transfer Function
(2017)In this paper a new analytic decomposed transfer function (DTF) for spaceborne SAR (Synthetic Aperture Radar) processing is calculated using the stationary phase approximation and Taylor’s series expansion. The DTF copes ... -
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 ... -
Correlation between sediment properties and seafloor characterization maps based on multibeam backscatter data from three regions off the coast of Norway
(2017)Multibeam echo sounder data from Kongsberg EM 1002 and EM 710 (70– 100 kHz) acquired between 2003 and 2014 were processed using QPS Fledermaus Geocoder Toolbox (FMGT) to produce backscatter mosaics and maps of estimated ... -
Characterization of Variable Density 3D Printed Materials for Broadband GRIN Lenses
(2017)In this work we design, simulate, manufacture and measure blocks made of variable density plastic. The density is controlled through varying the size of small cubes at the intersections of a fine grid. This structure is ... -
Tiered Modelling - A Solution to Hyper-Coherent Morphological Models?
(2017)Morphological models that comprise few constraints between parameter values are considered hyper-coherent. A high degree of coherence in a model can be a problem if it results in a large and unwieldy solution space. This ... -
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 ... -
Predicting Basic Military Performance for Conscripts in theNorwegian Armed Forces
(2017)The Norwegian Armed Forces have made major changes to the enlistment and selection system for conscripts in recent years. In this article, the predictive validity of various selection criteria for military performance is ... -
Results of a Ka Band Campaign for the Characterisation of Propagation Conditions for SatCom Systems at High Latitudes
(2017)Satellite services in the High North are utilized extensively for both communication purposes and for earth and climate observations. This paper presents results of two year measurements at 20 GHz and co-sited meteorological ... -
Smokeless GAP-RDX Composite Rocket Propellants Containing Diaminodinitroethylene (FOX-7)
(2017)Composite rocket propellants prepared from nitramine fillers (RDX or HMX), glycidyl azide polymer (GAP) binder and energetic plasticizers are potential substitutes for smokeless double-base propellants in some rocket motors. ...
