An ATR architecture for algorithm development and testing
(2013)A research platform with four cameras in the infrared and visible spectral domains is under development at the Norwegian Defence Research Establishment (FFI). The platform will be mounted on a high-speed jet aircraft and ... -
Augmented Lagrangian method for an Euler's elastica based segmentation model that promotes convex contours
(2017)In this paper, we propose an image segmentation model where an L1 variant of the Euler's elastica energy is used as boundary regularization. An interesting feature of this model lies in its preference for convex segmentation ... -
Augmenting Radar Doppler Resolution with Neural Networks
(2021-12-08)In order to generate high-resolution Doppler profiles a radar needs to emit a large number of pulses within a coherent processing interval (CPI). For a radar operating in demanding scenarios it can be difficult to sustain ... -
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 ... -
Automatic object recognition within point clouds in clustered or scattered scenes
(2020)We consider the problem of automatically locating, classifying and identifying an object within a point cloud that has been acquired by scanning a scene with a ladar. The recent work [E. Bae, Automatic scene understanding ... -
Automatic scene understanding and object identification in point clouds
(2019-10-10)A ladar can acquire a dense set of 3D coordinates of a scene, a so-called point cloud, in sub-second time from ranges of several kilometers. This paper presents algorithms for segmenting a point cloud into meaningful classes ... -
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 ... -
Automating Behaviour Tree Generation for Simulating Troop Movements
(2018-08-08)Computer generated forces are simulated units that are used in simulation based training and decision support in the military. These simulations are used to help trainees build a mental model of how different scenarios ... -
Automating Event-B invariant proofs by rippling and proof patching
(2019-01-02)The use of formal method techniques can contribute to the production of more reliable and dependable systems. However, a common bottleneck for industrial adoption of such techniques is the needs for interactive proofs. We ... -
Autonomous Optical Survey Based on Unsupervised Segmentation of Acoustic Backscatter
(2018)The application of acoustics to study the seabed have for decades provided industry and science with valuable information, and is still excels in terms of spatial coverage and detail. An acoustic response from the seabed ... -
Autonomous, Cooperative UAV Operations Using COTS Consumer Drones and Custom Ground Control Station
(2018)The benefits of using UA Vs for inexpensive aerial surveillance and survey have been widely accepted, and UAVs are routinely assisting humans performing ISR operations. While large countries and well-funded military ... -
Autophagic activity in BC3H1 cells exposed to yessotoxin
(2016)The marine toxin yessotoxin (YTX) can induce programmed cell death through both caspase-dependent and -independent pathways in various cellular systems. It appears to stimulate different forms of cellular stress causing ... -
Avoidance responses of minke whales to 1?4 kHz naval sonar
(2017)Minke whales are difficult to study and little information exists regarding their responses to anthropogenic sound. This study pools data from behavioural response studies off California and Norway. Data are derived from ... -
BAKTRAK: Backtracking drifting objects using an iterative algorithm with a forward trajectory model
(2012)The task of determining the origin of a drifting object after it has been located is highly complex due to the uncertainties in drift properties and environmental forcing (wind, waves, and surface currents). Usually, the ... -
Band structures and Z2 invariants of two-dimensional transition metal dichalcogenide monolayers from fully relativistic Dirac-Kohn-Sham theory using Gaussian-type orbitals
(2023-06-02)Two-dimensional (2D) materials exhibit a wide range of remarkable phenomena, many of which owe their existence to the relativistic spin-orbit coupling (SOC) effects. To understand and predict properties of materials ... -
Bandwidth optimizations for standards-based publish/subscribe in disadvantaged grids
(2012)NATO has identified Web services as a key enabler for its network enabled capability. Web services facilitate interoperability, easy integration and use of commercial off-the-shelf components, and while request/response-based ... -
A Bayesian Network Approach to Evaluating the Effectiveness of Modern Mine Hunting
(2021-10-29)This paper describes a novel technique for estimating how many mines remain after a full or partial underwater mine hunting operation. The technique applies Bayesian fusion of all evidence from the heterogeneous sensor ... -
Bayesian seabed classification using angle-dependent backscatter data from multibeam echo sounders
(2014)Acoustical seabed classification is a technology for mapping seabed sediments. Processed multibeam sonar data yield the variation of the seabed scattering strength with incidence angle, and this paper examines the effect ... -
Behavior of captive herring exposed to naval sonar transmissions (1.0-1.6 kHz) throughout a yearly cycle
(2012)Atlantic herring, Clupea harengus, is a hearing specialist, and several studies have demonstrated strong responses to man-made noise, for example, from an approaching vessel. To avoid negative impacts from naval sonar ... -
Behavioral changes following PCB 153 exposure in the Spontaneously Hypertensive rat - an animal model of Attention-Deficit/Hyperactivity disorder
(2014)Background Attention-Deficit/Hyperactivity Disorder (ADHD) is a behavioral disorder affecting 3-5% of children. Although ADHD is highly heritable, environmental factors like exposure during early development to various ...
