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, ... -
Robust Identification of Concealed Dangerous Substances by Spectral Correlation of Terahertz Transmission Images
(2015)Terahertz (THz) images containing spectral information in each pixel are recorded in transmission mode using a fiber-coupled time-domain spectroscopy system. The images are acquired by mounting a sample holder on an x-y ... -
Robust identification of concealed dangerous substances using THz imaging spectroscopy
(2015)False alarm rates must be kept sufficiently low if a method to detect and identify objects or substances is to be implemented in real life applications. This is also true when trying to detect and identify dangerous ... -
Robust Web Services in Heterogeneous Military Networks
(2010)NATO Network Enabled Capability is firstand foremost about achieving better interactionbetween the different actors involved in militaryoperations. This implies more efficient exchangeof information. Consequently, the NATO ... -
Robustness of adversarial camouflage (AC) for naval vessels
(2020-04-24)Different types of imaging sensors are frequently employed for detection, tracking and classification of naval vessels. A number of countermeasure techniques are currently employed against such sensors, and with the advent ... -
Role of the gerA operon in L-alanine germination of Bacillus licheniformis spores
(2012)Background The genome of Bacillus licheniformis DSM 13 harbours three neighbouring open reading frames showing protein sequence similarities to the proteins encoded from the Bacillus subtilis subsp. subtilis 168 gerA ... -
Russia and its Western Neighbours: A Comparative Study of the Security Situation in the Black, Baltic and Barents Sea Regions
(2019-12-17)Since Russia’s military intervention in Ukraine in 2014, the security situation of Europe’s eastern "frontline states" has undergone significant changes. In and around the Black Sea, the Baltic Sea and the Barents Sea, the ... -
Russia's Northern Fleet and the Oil Industry-Rivals or Partners? Petroleum, Security, and Civil-Military Relations in the Post-Cold War European Arctic
(2009)Described as one of the world's most promising new energy provinces, the European Arctic is no longer primarily seen as a military playground. Russia's approach to the region is increasingly governed by national economic ... -
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 ... -
Russian Rearmament: An Assessment of Defense-Industrial Performance
(2016)This article addresses two related questions associated with Russia’s rearmament program (GPV- 2020). First, it examines how the Russian defense industry has performed in the first five years of the rearmament program, ... -
Russland og Ukraina – krigsmål, virkemiddelbruk ogmåloppnåelse
(2023-05-02)Det sikkerhetspolitiske landskapet i Europa er i 2022 blitt endret på dramatisk vis. Russlands fullskala invasjon av Ukraina, som startet den 24. februar, utviklet seg raskt til å bli den største og mest ødeleggende krigen ... -
SARS-CoV-2 in the Air Surrounding Patients during Nebulizer Therapy
(2022-09-17)Nebulizer therapy is commonly used for patients with obstructive pulmonary disease or acute pulmonary infections with signs of obstruction. It is considered a “potential aerosol-generating procedure,” and the risk of disease ... -
Scaling Behavior of Quasi-One-Dimensional Vortex Avalanches in Superconducting Films
(2020-03-27)Scaling behaviour of dynamically driven vortex avalanches in superconducting YBa2Cu3O7−δ films deposited on tilted crystalline substrates has been observed using quantitative magneto-optical imaging. Two films with 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 ... -
Search by photo methodology for signature properties assessment by human observers
(2015)Reliable, low-cost and simple methods for assessment of signature properties for military purposes are very important. In this paper we present such an approach that uses human observers in a search by photo assessment of ... -
Security for Autonomous and Unmanned Devices: Cryptography and its Limits
(2022-02-07)We survey existing literature on protecting resource constrained autonomous and unmanned devices. The goal is to secure data both during transmission and at rest, also when facing highly skilled and motivated adversaries. ... -
Segmentation of PMSE data using random forests
(2022-06-22)EISCAT VHF radar data are used for observing, monitoring, and understanding Earth’s upper atmosphere. This paper presents an approach to segment Polar Mesospheric Summer Echoes (PMSE) from datasets obtained from EISCAT VHF ... -
Seismic exploration noise reduction in the marginal ice zone
(2014)A sonobuoy field was deployed in the Marginal Ice Zone of the Fram Strait in June 2011 to study the spatial variability of ambient noise. High noise levels observed at 10–200 Hz are attributed to distant (1400 km range) ... -
