The subway microbiome: Seasonal dynamics and direct comparison of air and surface bacterial communities
(2019-12-19)
Background
Mass transit environments, such as subways, are uniquely important for transmission of microbes among humans and built environments, and for their ability to spread pathogens and impact large numbers of people. ...
Predicting False Alarm Rates for High-Resolution Antisubmarine Warfare Sonars in a Cluttering Environment Prone to False Alarm Rate Inflation
(2019-09-13)
Operation of high-resolution, broadband, antisubmarine warfare sonars in littoral waters is challenging, since the presence of sea mounts, underwater ridges, and other topographic features causes increased false alarm ...
Ship-of-opportunity noise inversions for geoacoustic profiles of a layered mud-sand seabed
(2019-04-30)
This paper considers the use of broadband noise from a ship-of-opportunity in statistical inference for estimating geoacoustic parameters of a layered mud-sand seabed model via trans-dimensional (trans-D) Bayesian matched-field ...
Improved Passivation Effect Due to Controlled Smoothing of the CdTe-HgCdTe Interface Gradient by Thermal Annealing
(2019-07-11)
HgCdTe films grown by liquid phase epitaxy were passivated with CdTe grown by molecular beam epitaxy. A series of annealing tests with different temperatures and durations were then carried out in order to reach a two-fold ...
Characterization of (111)B and (211)B CdZnTe Substrates for HgCdTe Growth
(2019-06-13)
We have studied state-of-the-art CdZnTe (211)B and (111)B substrates and compared them to each other and to substrates from an alternative vendor. The CdZnTe surface has been characterized both as-received and after growth ...
Den autonome framtid
(2019-09-17)
Framtiden er ubemannet. Autonom betyr uavhengig. Med autonome systemer mener vi maskiner som løser opp-gaver på egen hånd. Det investeres store summer i slik teknologi både sivilt og militært. Grensene for hva autonome ...
Oversikt over FFIs vitenskapelige publiseringer i 2018
(2019-06-18)
Rapporten gir en oversikt over FFI-forskernes vitenskapelige publiseringer i fagtidsskrifter med fagfellevurdering og annen publisering med nivåinndeling. Oversikten er hentet ut fra den norske publiseringsbasen CRIStin, ...
Distributed fusion in underwater sensor networks: Fusing bearing information
(2019)
In underwater sensor networks, distributed data fusion may be more efficient than centralized fusion because the limited data transmission capacity can make it difficult to collect all required sensor information at a ...
Imaging radar for navigation and surveillance on an autonomous unmanned ground vehicle capable of detecting obstacles obscured by vegetation
(2019-09-16)
The Norwegian Defence Research Establishment (FFI), has developed a multi purpose radar demonstrator for Intelligence, Surveillance and Reconnaissance (ISR) on the Off-road Light Autonomous Vehicle (OLAV) platform. The ...
ESTIMATING RANGE DEPENDENT SEDIMENT THICKNESS AND REFLECTION COEFFICIENTS FROM BATHYMETRIC DATA FOR IMPROVED SONAR PERFORMANCE MODELLING
(2019)
Knowledge about the underwater environment is critical to anti-submarine warfare
operations in littoral waters. The sonar settings and depth selections can significantly affect
the predicted sonar performance. Bathymetry ...
