Measurements and modeling of effects of out-of-plane reverberation on the power delay profile for underwater acoustic channels
(2015)
Long reverberation tails are often observed in shallow-water acoustic channel impulse responses (CIRs). Examples from three significantly different environments along the Norwegian coast are presented. It is shown that 2-D ...
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 Security Classification by Machine Learning for Cross-Domain Information Exchange
(2015)
Cross-domain information exchange is necessary to obtain information superiority in the military domain, and should be based on assigning appropriate security labels to the information objects. Most of the data found in a ...
Wireless power transfer in the presence of metallic plates: Experimental results
(2013)
We demonstrate efficient wireless power transfer between two high Q resonators, especially in a complex electromagnetic environment. In the close proximity of metallic plates, the transfer efficiency stays roughly the same ...
Postnatal exposure to PCB 153 and PCB 180, but not to PCB 52, produces changes in measures of attention, activity level and impulsivity in outbred male Wistar Kyoto rats
(2011)
Background
Polychlorinated biphenyls (PCBs) are a class of organic compounds that bioaccumulate due to their chemical stability and lipophilic properties. Humans are prenatally exposed via trans-placental transfer, ...
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, ...
