Optical limiting properties and z-scan measurements of carbon disulfide at 2.05 μm wavelength
(2016)
Nonlinear and optical limiting properties of carbon disulfide (CS 2 ) are characterized at 2.05 μm wavelength using a 𝑄 -switched Ho:YLF laser with high pulse energy. The nonlinear refractive index of CS 2 is measured ...
Classification of birds and UAVs based on radar polarimetry
(2016)
This letter aims to show the potential of using polarimetric parameters to distinguish between large birds and unmanned aerial vehicles (UAVs) of comparable size in the context of a modern long-range air defense radar. ...
Sperm whales reduce foraging effort during exposure to 1-2 kH z sonar and killer whale sounds
(2016)
The time and energetic costs of behavioral responses to incidental and experimental sonar exposures, as well as control stimuli, were quantified using hidden state analysis of time series of acoustic and movement data ...
Measurements of high-frequency acoustic scattering from glacially eroded rock outcrops
(2016)
Measurements of acoustic backscattering from glacially eroded rock outcrops were made off the coast of Sandefjord, Norway using a high-frequency synthetic aperture sonar (SAS) system. A method by which scattering strength ...
A Study of the Detonation Properties, Propellant Impulses, Impact Sensitivities and Synthesis of Nitrated ANTA and NTO Derivatives
(2016)
Nitrated derivatives of 5-amino-3-nitro-1,2,4-triazole (ANTA)
and 3-nitro-1,2,4-triazol-5-one (NTO) were theoretically characterized with respect to their performance as high explosives and rocket propellants. The detonation ...
Increased CSF levels of aromatic amino acids in hip fracture patients with delirium suggests higher monoaminergic activity
(2016)
Background
To examine whether delirium in hip fracture patients was associated with changes in the levels of amino acids and/or monoamine metabolites in cerebrospinal fluid (CSF) and serum.
Methods
In this ...
Classification of Ships Using Real and Simulated Data in a Convolutional Neural Network
(2016)
Convolutional neural networks (CNNs) have recently been applied successfully in large scale image classification competitions for photographs found on the Internet. As our brains are able to recognize objects in the images, ...
The Influence of Predeployment Training on Coordination in Multinational Headquarters:The Moderating Role of Organizational Obstacles to Information Sharing.
(2016)
Coordination is critical to the success of multinational military operations and may be fostered by predeployment training. We argue that whether such training is related to a high degree of perceived coordination at the ...
Low-Complexity Adaptive Sonar Imaging
(2016)
We have studied the low-complexity adaptive (LCA) beamformer in active sonar imaging. LCA can be viewed as either a simplification of the minimum variance distortionless response (MVDR) beamformer, or as an adaptive extension ...
Signal environment mapping of the Automatic Identification System frequencies from space
(2016)
This paper presents received signal strength data recorded by the NORAIS Receiver on the four VHF channels allocated to the use of the Automatic Identification System (AIS). The NORAIS Receiver operated on-board the Columbus ...
