Sensemaking and decision-making in a joint military context: The role of translating, verifying and prioritizing information
(2018)This article, based on fieldwork during a military exercise in Norway, analyzes how new technology is used in joint operations by military personnel and how it is connected to sense-making and decision-taking. The authors' ... -
Sensitivity of input parameters to modelling of atmospheric transmission of long-wave infrared radiation at sea under warm and humid conditions
(2018)A joint Australian-Norwegian eld trial (Osprey) was held in February 2018 in Darwin, Australia. The objective of this trial was to measure IR transmission properties of the atmosphere in a marine environment under warm and ... -
Sensor noise informed representation of hyperspectral data, with benefits for image storage and processing
(2011)Many types of hyperspectral image processing can benefit from knowledge of noise levels in the data, which can be derived from sensor physics. Surprisingly, such information is rarely provided or exploited. Usually, the ... -
Serial Ricinine Levels in Serum and Urine after Ricin Intoxication
(2013)Ricinine is an alkaloid present in the castor bean plant (Ricinus communis) that can be used as a biomarker for ricin poisoning. Serial ricinine levels are reported in the serum and urine of a patient suffering from ... -
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 ... -
Severe gunshot injuries in a porcine model: impact on central markers of innate immunity
(2011)Background The mechanisms behind lipopolysaccharide (LPS) tolerance remain obscure. LPS signals through Toll-like receptor 4 (TLR4) and severe trauma/haemorrhage may influence binding and signalling through this receptor, ... -
Severity Scoring of Behavioral Responses of Sperm Whales (Physeter macrocephalus) to Novel Continuous versus Conven tional Pulsed Active Sonar
(2021-04-19)Controlled exposure experiments (CEEs) have demonstrated that naval pulsed active sonar (PAS) can induce costly behavioral responses in cetaceans similar to antipredator responses. New generation continuous active sonars ... -
Sex differences in the physiological response to a demanding military field exercise
(2020)Purpose To investigate sex differences in the effect of a military field exercise on physical performance, body composition, and blood biomarkers. Methods Measurements were done in 23 male and 12 female conscripts ... -
Ship source level estimation and uncertainty quantification in shallow water via Bayesian marginalization
(2020-04-17)This paper applies a non-linear Bayesian marginalization approach to ship spectral source level estimation in shallow water with unknown seabed properties and uncertain source depth. The algorithm integrates the posterior ... -
Ship tracking results from state-of-the-art space-based AIS receiver systems for maritime surveillance
(2019-04-11)Norway currently operates four satellites with Automatic Identification System (AIS) receivers. The first-generation satellites, AISSat-1 and AISSat-2, are equipped with a two-channel, single-antenna AIS receiver, while ... -
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 ... -
Should I Stay or Should I Go? Explaining Variation in Western Jihadists' Choice between Domestic and Foreign Fighting
(2013)This article studies variation in conflict theater choice by Western jihadists in an effort to understand their motivations. Some militants attack at home, whereas others join insurgencies abroad, but few scholars have ... -
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 ... -
Simplified energy landscape for modularity using total variation
(2018)Networks capture pairwise interactions between entities and are frequently used in applications such as social networks, food networks, and protein interaction networks, to name a few. Communities, cohesive groups of nodes, ... -
Simplified measurement of point spread functions of hyperspectral cameras for assessment of spatial coregistration
(2019-05-14)In multi- and hyperspectral imaging, spatial coregistration of the point spread functions (PSFs) of all bands within each pixel is critical for the integrity of measured spectra. There is a need to define a standardized ... -
Simulating CSF flow dynamics in the normal and chiari I subarachnoid space during rest and exertion
(2013)BACKGROUND AND PURPOSE: CSF fluid dynamics in healthy subjects and patients with Chiari I have been characterized during rest with phase-contrast MR imaging and CFD. CSF flow velocities and pressures in the nonresting state ... -
A simulation of cross-country skiing on varying terrain by using a mathematical power balance model
(2013)The current study simulated cross-country skiing on varying terrain by using a power balance model. By applying the hypothetical inductive deductive method, we compared the simulated position along the track with actual ... -
Simulation of infrared avalanche photodiodes from first principles
(2017)The present article deals with device physics and modeling of an Hg0.28Cd0.72Te wide-area electron-initiated avalanche photodiode, with main input data extracted from first principles electronic structure codes. Due to the ... -
Simulation of natural fragmentation of rings cut from warheads
(2015)Natural fragmentation of warheads that detonates causes the casing of the warhead to split into various sized fragments through shear or radial fractures depending on the toughness, density, and grain size of the material. ... -
