Three-Site Diversity at Ka-Band Satellite Links in Norway: Gain, Fade Duration and the Impact of Switching Schemes
(2017)
Analysis of two years of measurements from a three-site satellite beacon diversity experiment in Norway is presented. The operating frequency was 19.68 GHz, elevation angles were between 21.7° and 22°, and site separations ...
Large-eddy simulations of dense-gas dispersion within a high-Reynolds number turbulent boundary layer
(2017)
Large-eddy simulations of flows over a backward-facing step with release of four different gases with increasing densities have been performed. The results have been analysed with particular emphasis on the part of the ...
Software-Defined Underwater Acoustic Modems: Historical Review and the NILUS Approach
(2017)
Flexible/adaptive acoustic modems that are reprogrammable/reconfigurable at all layers of the communication stack, either by a user or by means of autonomous decisions, are considered as an important enabler for interoperability ...
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 ...
Simulation of infrared avalanche photodiodes from first principles
(2017)
The present article deals with device physics and modeling of an Hg0.28Cd0.72Te wide-area electron-initiated avalanche photodiode, with main input data extracted from first principles electronic structure codes. Due to the ...
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 ...
