Disturbance-specific social responses in long-finned pilot whales, Globicephala melas
(2016)Social interactions among animals can influence their response to disturbance. We investigated responses of long-finned pilot whales to killer whale sound playbacks and two anthropogenic sources of disturbance: tagging ... -
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 ... -
Bond strength and performance of optical fibre Bragg gratings sensors embedded in composite patch repairs for military aircraft
(2016)Structural health monitoring (SHM) systems are recognized as a key element in a modern and efficient approach to structural lifecycle management. With novel applications of advanced materials, such as extensive use of ... -
Radar sensitivity to human heartbeats and respiration
(2015)Human heartbeats and respiration can be detected from a distance using radar. This can be used for medical applications and human being detection. It is useful to have a system independent measure of how detectable the ... -
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 ... -
Oscillatory regimes of the thermomagnetic instability in superconducting films
(2016)The stability of superconducting films with respect to oscillatory precursor modes for thermomagnetic avalanches is investigated theoretically. The results for the onset threshold show that previous treatments of nonoscillatory ... -
Effects of exercise mode, energy, and macronutrientinterventions on inflammation during military training
(2016)Load carriage (LC) exercise may exacerbate inflammation during training. Nutritional supplementation may mitigate this response by sparing endogenous carbohydrate stores, enhancing glycogen repletion, and attenuating ... -
High-pulse-energy mid-infrared fractional-image-rotation-enhancement ZnGeP2 optical parametric oscillator
(2016)A high-energy mid-infrared ZnGeP 2 (ZGP) optical parametric oscillator (OPO) based on the nonplanar fractional-image-rotation enhancement resonator pumped by a 2.05 μm Ho 3+ :YLF laser is presented. Up to 120 mJ pulse ... -
The Seven Ways to Find Heading
(2016)A magnetic compass has too large a heading error for many applications, and it is often not obvious how to achieve an accurate heading, in particular for low-cost navigation systems. However, there are several different ... -
Quantifying the tracking capability of space-based AIS systems
(2016)The Norwegian Defence Research Establishment (FFI) has operated three Automatic Identification System (AIS) receivers in space. Two are on dedicated nano-satellites, AISSat-1 and AISSat-2. The third, the NORAIS Receiver, ... -
Mathematical relations related to the lode parameter for studies of ductility
(2016)During plastic flow, hydrostatic pressure and plastic strain control the size of the yield surface while the Lode angle is responsible for its shape. The von Mises yield condition shows no dependency of the Lode angle ... -
Computing turbulence structure tensors in plane channel flow
(2016)This paper is concerned with the computation of turbulence structure tensors in plane channel flow. It has been pointed out that the previously computed turbulence structure tensors, for this configuration, used an ... -
All solid-state spectral broadening: An average and peak power scalable method for compression of ultrashort pulses
(2016)Spectral broadening in bulk material is a simple, robust and low-cost method to extend the bandwidth of a laser source. Consequently, it enables ultrashort pulse compression. Experiments with a 38 MHz repetition rate, 50 ... -
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 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, ... -
A new standard for predicting lung injury inflicted by Friedlander blast waves
(2016)An important blast injury mechanism is the rupture of the lungs and the gastrointestinal tract. In explosives safety studies and threat analysis the empirical model of Bowen is often used to quantify this mechanism. The ... -
Defence industrial policy – a sound security strategy or an economic fallacy?
(2016)This article explores whether it makes sense for national governments to employ defence industrial policies – such as offsets and discriminatory procurement practices – to support their domestic defence industries. This ... -
Behavioral side effects of prophylactic therapies against soman-induced seizures and lethality in rats
(2014)Four medical therapies previously shown to exert varying degrees of protection against a convulsant dose of soman were assessed for potential behavioral side effects in a novelty test. In Experiment 1, HI-6 (1-[([4-(amin ... -
Computer-assisted image processing to detect spores from the fungus Pandora neoaphidis
(2016)This contribution demonstrates an example of experimental automatic image analysis to detect spores prepared on microscope slides derived from trapping. The application is to monitor aerial spore counts of the entomopathogenic ... -
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 ...
