Compact multispectral multi-camera imaging system for small UAVs
(2016)Cameras with filters in the focal plane provide the most compact solution for multispectral imaging. A small UAV can carry multiple such cameras, providing large area coverage rate at high spatial resolution. We investigate ... -
Architectural work for modeling and simulation combining the NATO Architecture Framework and C3 Taxonomy
(2016)To provide modeling and simulation functionality as services is strategically leveraged in the defense domain and elsewhere. To describe and understand the context, the ecosystem, wherein such services are used and ... -
Source Localization With Multiple Hydrophone Arrays via Matched-Field Processing
(2016)This paper considers approaches to combining information from multiple arrays in matched-field processing (MFP) for underwater acoustic source localization. The standard approach is to apply conventional MFP for each array ... -
Automatic detection of marine gas seeps using an interferometric sidescan sonar
(2016)There is a significant need for reliable, cost-effective, and preferably automatic methods for detecting and monitoring marine gas seeps. Seeps at the seafloor may originate from natural sources including sediments releasing ... -
Microbial community structure in a full-scale anaerobic treatment plant during start-up and first year of operation revealed by high-throughput 16S rRNA gene amplicon sequencing
(2016)High-throughput amplicon sequencing of six biomass samples from a full-scale anaerobic reactor at a Norwegian wood and pulp factory using Biothane Biobed Expanded Granular Sludge Bed (EGSB) technology during start-up and ... -
Near-PHz-bandwidth, phase-stable continua generated from a Yb:YAG thin-disk amplifier
(2016)We report on the generation of a multi-octave, phase-stable continuum from the output of a Yb:YAG regenerative amplifier delivering 1-ps pulses with randomly varying carrier-envelope phase (CEP). The intrinsically CEP-stable ... -
FESTER: a propagation experiment, overview and first results
(2016)A long term field trial called FESTER (First European South African Transmission Experiment) has been conducted by an international collaboration of research organizations during the course of almost one year at False Bay, ... -
Protecting our food: Can standard food safety analysis detect adulteration of food products with selected chemical agents?
(2016)The food we eat and water we drink is routinely tested for a range of biological and chemical contaminants, which can be hazardous to human health, as part of food safety legislative requirements. The vulnerability of the ... -
24 Hour Test of a Fuel Cell System for an Autonomous Underwater Vehicle
(2016)The Norwegian Defence Research Establishment (FFI) has a long experience with power sources for autonomous underwater vehicles (AUVs). FFI has designed and built a power supply system based on a water-cooled and air-supplied ... -
Optical limiting properties of carbon disulfide at 2.05μm wavelength
(2016)Several types of infrared sensors are based on sensitive focal plane arrays. In such sensors, the intensity will typically increase by a factor ~107 at the focal plane, compared to the intensity of the incoming radiation. ... -
Formation of Range-Doppler Maps Based on Sparse Reconstruction
(2016)This paper presents an application of compressed sensing in a pulsed system, such as a radar or sonar to form range-Doppler maps. Instead of transmitting a train of pulses, we portrait a system where the pulse emission ... -
High-pulse-energy mid-infrared fractional-image-rotation-enhancement ZnGeP2 optical parametric oscillator
(2016)A high-energy mid-infrared ZnGeP 2 (ZGP) optical parametric oscillator (OPO) based on the nonplanar fractional-image-rotation enhancement resonator pumped by a 2.05 μm Ho 3+ :YLF laser is presented. Up to 120 mJ pulse ... -
Computer-assisted image processing to detect spores from the fungus Pandora neoaphidis
(2016)This contribution demonstrates an example of experimental automatic image analysis to detect spores prepared on microscope slides derived from trapping. The application is to monitor aerial spore counts of the entomopathogenic ... -
In operando neutron diffraction study of a commercial graphite/(Ni, Mn, Co) oxide-based multi-component lithium ion battery
(2016)In situ neutron diffraction was employed to investigate the structural evolution of the electrode materials in an ICR 10440 commercial cylindrical lithium-ion battery, which has a discharge capacity of 360 mAh and a nominal ... -
Why Putin went to war: ideology, interests and decision-making in the Russian use of force in Crimea and Donbas
(2016)Russia’s 2014 annexation of Crimea, and the country’s prominent role in instigating and supporting an anti-Kiev rebellion in Donbas, surprised the world. This study seeks to explain Russian behaviour in these two cases. ... -
Effects of Supplemental Energy on Protein Balance during 4-d Arctic Military Training
(2016)Soldiers often experience negative energy balance during military operations that diminish whole-body protein retention, even when dietary protein is consumed within recommended levels (1.5-2.0 g[middle dot]kg-1[middle ... -
Comparative visualization of multiple time surfaces by planar surface reformation
(2016)Comparing time surfaces at different integration time points, or from different seeding areas, can provide valuable insight into transport phenomena of fluid flows. Such a comparative study is challenging due to the often ... -
