Spectral properties of multilayered oak leaves and a camouflage net: experimental measurements and mathematical modelling
(2021-09-21)
The development of state-of-the-art surveillance technology forces nations to develop camouflage with advanced capabilities. Owing to the abundance and wide distribution of leaves, their spectral properties are often ...
Human performance research for military operations in extreme cold environments
(2020)
Objectives
Soldier performance in the Arctic depends on planning and training, protective equipment, and human physiological limits. The purpose of this review was to highlight the span of current research on enhancing ...
Øke bemanningen i Forsvaret i dramatisk nedgangskonjunktur? En samfunnsøkonomisk vurdering
(2021)
Koronapandemien har resultert i kraftige fall i etterspørsel, produksjon og sysselsetting i Norge
og internasjonalt. Arbeidsledigheten i Norge er nå unormalt høy. Arbeidsøkonomisk litteratur
har påvist at det er kostbart ...
Multibeam Echosounder With Orthogonal Waveforms: Feasibility and Potential Benefits
(2021-04-15)
Modern multibeam echosounders (MBE) employ frequency-division techniques (FDT) to ensonify multiple sectors within the same ping cycle. This leads to improved performance in coverage rate, and yaw and pitch stabilization. ...
Spatial coherence of speckle for repeat-pass synthetic aperture sonar micronavigation
(2021-03-31)
Accurate positioning of autonomous underwater vehicles is a major challenge. The long-term drift is problematic if global position updates are not available, and for applications such as repeat-pass interferometry and ...
Formation Path Following Control of Underactuated USVs
(2021-06-30)
This paper proposes a formation control method for two underactuated unmanned surface vessels (USVs) to follow curved paths in the presence of ocean currents. By uniting a line-of-sight (LOS) guidance law and the ...
Characterizing the dynamic range of a hyperspectral camera
(2021-04-12)
The dynamic range of a hyperspectral camera can have a strong impact on the quality and integrity of the collected spectra. For the image sensor chip alone, the dynamic range is the ratio between the saturation level and ...
Severity Scoring of Behavioral Responses of Sperm Whales (Physeter macrocephalus) to Novel Continuous versus Conven tional Pulsed Active Sonar
(2021-04-19)
Controlled exposure experiments (CEEs) have demonstrated that naval pulsed active sonar (PAS) can induce costly behavioral responses in cetaceans similar to antipredator responses. New generation continuous active sonars ...
CBAM: A Contextual Model for Network Anomaly Detection
(2021)
Anomaly-based intrusion detection methods aim to combat the increasing rate of zero-day attacks, however, their success is currently restricted to the detection of high-volume attacks using aggregated traffic features. ...
Evaluation of Message Broker Approaches for Information Exchange in Disadvantaged Tactical Networks in a Federated Environment
(2020)
The research task group NATO STO/IST-150 «NATO Core Services profiling for Hybrid Tactical Networks» is working towards profiling Core Services for the tactical domain, which can be described as DIL (disconnected, intermittent ...
