3-D Printed Monolithic GRIN Dielectric-Loaded Double-Ridged Horn Antennas
(2019-09-06)
Monolithic integration of 3-D printed gradient index (GRIN) dielectric loading with a double-ridged rectangular horn standard gain horn (SGH) and its impact on antenna performance are demonstrated. Results show that the ...
Challenges for Risk and Security Modelling in Enterprise Architecture
(2019-11-19)
From our experience cooperating with the Norwegian Armed Forces, we outline two interconnected challenges for modelling risk and security in an enterprise architecture: (1) modelling what is protected and why it is protected ...
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 ...
Assessment of intake of copper and lead by sheep grazing on a shooting range for small arms: a case study.
(2018-04-11)
The Norwegian Armed Forces’ shooting ranges contain contamination by metals such as lead (Pb) and copper (Cu) and are often used as grazing pastures for livestock. To determine whether the sheep were at risk from grazing ...
Validation of replay-based underwater acoustic communication channel simulation
(2013)
This paper discusses validation methods for underwater acoustic communication channel simulators, and validates direct and stochastic replay of underwater acoustic communication channels as implemented in a channel simulator ...
Estimating the pixel footprint distribution for image fusion by ray tracing lines of sight in a Monte Carlo scheme
(2013)
Images from airborne cameras can be a valuable resource for data fusion, but this typically requires them to be georeferenced. This usually implies that the information of every pixel should be accompanied by a single ...
