Predicting acoustic dose associated with marine mammal behavioural responses to sound as detected with fixed acoustic recorders and satellite tags
(2019-03-08)To understand the consequences of underwater noise exposure for cetaceans, there is a need for assessments of behavioural responses over increased spatial and temporal scales. Bottom-moored acoustic recorders and satellite ... -
Predicting Basic Military Performance for Conscripts in theNorwegian Armed Forces
(2017)The Norwegian Armed Forces have made major changes to the enlistment and selection system for conscripts in recent years. In this article, the predictive validity of various selection criteria for military performance is ... -
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 ... -
Predicting Near-Time Satellite Signal Attenuation at Ka-band Using Tropospheric Weather.
(2018-12-10)There are satellite communication applications where it is desirable to predict near time (e.g. 2 to 12 h) propagation losses at Ka-band due to hydrometeor precipitation. We present results from a project investigating the ... -
Preparation and characterisation of epoxy/alumina polymer nanocomposites
(2013)The effect of adding nanosized alumina fillers of both fibre-like and spherical shapes to an epoxy polymer has been investigated. The alumina was dispersed in the epoxy hardener using two different sonication techniques. ... -
Pretreatment and prophylaxis against nerve agent poisoning: are undesirable behavioral side effects unavoidable?
(2016)The threat of chemical warfare agents like nerve agents requires life saving measures of medical pretreatment combined with treatment after exposure. Pretreatment (pyridostigmine) may cause some side effects in a small ... -
Pro-inflammatory cytokines in cystic glioblastoma: A quantitative study with a comparison with bacterial brain abscesses. With an MRI investigation of displacement and destruction of the brain tissue surrounding a glioblastoma
(2022-07-29)Cystic glioblastomas are aggressive primary brain tumors that may both destroy and displace the surrounding brain tissue as they grow. The mechanisms underlying these tumors’ destructive effect could include exposure of ... -
Probabilistic estimation of merchant ship source levels in an uncertain shallow-water environment
(2021-11-13)The estimation of ship source levels (SSLs) in shallow-water environments can be complicated by sound interaction with the seabed. Uncertainty in seabed properties influences SSL estimates, and it is of interest to mitigate ... -
Projected area and drag coefficient of high velocity irregular fragments that rotate or tumble
(2017)3 degrees of freedom (DOF) exterior ballistic computer models are used in fragment studies to calculate individual trajectories of each fragment based on drag coefficient and the projected (presented) area in the direction ... -
Propagation and scattering effects in underwater acoustic communication channels
(2013)Systematic measurements were performed to characterize shallow-water acoustic propagation channels for applications in the field of underwater communications. The survey was conducted in northern Europe and covers the ... -
Propionate enters GABAergic neurons, inhibits GABA transaminase, causes GABA accumulation and lethargy in a model of propionic acidemia
(2018)Propionic acidemia is the accumulation of propionate in blood due to dysfunction of propionyl-CoA carboxylase. The condition causes lethargy and striatal degeneration with motor impairment in humans. How propionate exerts ... -
Protecting our food: Can standard food safety analysis detect adulteration of food products with selected chemical agents?
(2016)The food we eat and water we drink is routinely tested for a range of biological and chemical contaminants, which can be hazardous to human health, as part of food safety legislative requirements. The vulnerability of the ... -
Publish/Subscribe Versus a Content-Based Approach for Information Dissemination
(2019-01-03)NATO has identified the WS-Notification standard from OASIS to support event-driven communication in the NATO enterprise and when building coalition networks. Using this standard promotes interoperability. However, there ... -
Quantification of aerosol dispersal from suspected aerosol-generating procedures
(2021-12-06)Background Oxygen-delivering modalities like humidified high-flow nasal cannula (HFNC) and noninvasive positive-pressure ventilation (NIV) are suspected of generating aerosols that may contribute to transmission of disease ... -
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, ... -
The Queen Bees and the Women's Team - A contextual examination of enmity and friendship between military women
(2018)In several studies of women in the Norwegian Armed Forces, we have found an assertion that female groups are so riddled with conflicts and enmity that it is preferable to keep women few in number and mixed up ... -
Radar imager for Mars’ subsurface experiment—RIMFAX
(2020-11-03)The Radar Imager for Mars’ Subsurface Experiment (RIMFAX) is a Ground Penetrating Radar on the Mars 2020 mission’s Perseverance rover, which is planned to land near a deltaic landform in Jezero crater. RIMFAX will add a ... -
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 ...
