SARS-CoV-2 in the Air Surrounding Patients during Nebulizer Therapy
(2022-09-17)Nebulizer therapy is commonly used for patients with obstructive pulmonary disease or acute pulmonary infections with signs of obstruction. It is considered a “potential aerosol-generating procedure,” and the risk of disease ... -
Scaling Behavior of Quasi-One-Dimensional Vortex Avalanches in Superconducting Films
(2020-03-27)Scaling behaviour of dynamically driven vortex avalanches in superconducting YBa2Cu3O7−δ films deposited on tilted crystalline substrates has been observed using quantitative magneto-optical imaging. Two films with different ... -
Scenario modelling with morphological analysis
(2017)Scenarios can serve as points of reference in the future for decisions that we have to make today. Morphological analysis provides a structured method for ensuring consistency and relevance in scenario development. This ... -
Search by photo methodology for signature properties assessment by human observers
(2015)Reliable, low-cost and simple methods for assessment of signature properties for military purposes are very important. In this paper we present such an approach that uses human observers in a search by photo assessment of ... -
Security for Autonomous and Unmanned Devices: Cryptography and its Limits
(2022-02-07)We survey existing literature on protecting resource constrained autonomous and unmanned devices. The goal is to secure data both during transmission and at rest, also when facing highly skilled and motivated adversaries. ... -
Segmentation of PMSE data using random forests
(2022-06-22)EISCAT VHF radar data are used for observing, monitoring, and understanding Earth’s upper atmosphere. This paper presents an approach to segment Polar Mesospheric Summer Echoes (PMSE) from datasets obtained from EISCAT VHF ... -
Seismic exploration noise reduction in the marginal ice zone
(2014)A sonobuoy field was deployed in the Marginal Ice Zone of the Fram Strait in June 2011 to study the spatial variability of ambient noise. High noise levels observed at 10–200 Hz are attributed to distant (1400 km range) ... -
Selected Issues of QoS Provision in Heterogenous Military Networks
(2014)Tactical ad-hoc networks are evolving today towards complex heterogeneous networks in terms of architecture, protocols and security. Due to the difference in network resources and reliability, end-to-end quality of service ... -
Selective adsorption of lead, copper and antimony in runoff water from a small arms shooting range with a combination of charcoal and iron hydroxide
(2015)Metals and metalloids from ammunition residues at small arms shooting ranges leach into the soil and surrounding watercourses and may pose a threat to exposed wildlife and humans. To reduce the potential impact of heavy ... -
Semantic Service Discovery for Interoperability in Tactical Military Networks
(2010)Interoperability, both inter- and intra-nation, is a main concern when attempting to fully realize NATO Network Enabled Capabilities (NNEC). The NNEC vision implies an information infrastructure that supports prioritized access ... -
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 ... -
