Pilot Whales Attracted to Killer Whale Sounds: Acoustically-Mediated Interspecific Interactions in Cetaceans
(2012)In cetaceans’ communities, interactions between individuals of different species are often observed in the wild. Yet, due to methodological and technical challenges very little is known about the mediation of these ... -
Pilotstudie ernæring – test av alternative matprodukter i arktiske feltrasjoner
(2023-03-06)Flere studier har vist at krevende militære feltøvelser leder til et betydelig energiunderskudd hos soldatene. Soldater inntar daglig omtrent 3000 kcal, selv om energiforbruket kan komme opp i 6000 kcal og de har mer mat ... -
Pixel scaling in infrared focal plane arrays
(2013)We discuss effects that arise in pixels of IR focal plane arrays (FPAs) when pixel size scales down to approach the wavelength of the incident radiation. To study these effects, we perform first-principles electromagnetic ... -
PlaneRay: an acoustic underwater propagation model based on ray tracing and plane-wave reflection coefficients
(2008)PlaneRay is a ray tracing program for underwater acoustic propagation modeling that can treat moderately range-varying scenarios. The model uses a unique sorting and interpolation routine for efficient determination of a ... -
Planned and early results of low elevation angle measurements at Ka-band from two projects in Norway
(2013-03-15)Geostationary satellite fixed communication services for high latitude and mostly maritime environment are increasingly important for Norway and the regions in the high north in general. Although measurement results have ... -
Planning and conducting crisis management exercises for decision-making: the do’s and don’ts
(2017)Organizations exercise to strengthen their crisis management capability, to identify possible improvements to plans, and to develop necessary skills. Taking part in exercises is one way leaders can test their decision-making ... -
Plasma Cytokine Profiles in Long-Term Strenuous Exercise
(2016)The open window theory indicates altered immunity 3 to 72 hours after exercise. The J-curve describes the risk of illness in response to exercise. The aim of this study was to examine the secretion of proinflammatory and ... -
Plasticity computation in hydrocodes compared with analytical theory
(2000)Associated analytical plasticity theory is reviewed and compared with the approach to plasticity used in hydrocodes such as Autodyn and Dyna. In general, the two methods are seen to be quite different, but for certain special ... -
Point detection in textured ultrasound images
(2023-02-26)Detection of point scatterers in textured ultrasound images can be challenging. This paper investigates how four multilook methods can improve the detection. We analyze many images with known point scatterer locations and ... -
Polarimetric scattering calculation based on Maxwells equations for very high resolution SAR
(2004)A method for raw signal generation for extended SAR (Synthetic Aperture Radar) scenes with very high resolution is described. Such a simulator shall handle resolution better than 30 cm, squinted geometry, elliptical orbit ... -
Polarization dependence in CHESS fiber optic strain monitoring system based on fiber Bragg gratings
(2002)This report describes the polarization dependence in the hull monitoring system CHESS, developed in FFI project 79301 CHESS II. The report describes the polarization behaviour of some main components in the system, ... -
Police forces with military status in international peace operations - preliminary findings
(2002)Recent peace operations are characterised by a gap between a large number of heavily-armed military forces and the international civilian police – often few in number and if at all equipped with light weapons (the so-called ... -
Policy og praksis for gjenkjøp - en komparativ studie av sju nasjoner
(2006)The Norwegian offset guidelines are up for revision, and this study has been part of a process of establishing a new Norwegian offset policy and practice. The purpose of this report has been to conduct a comparative study ... -
Polycarbonate in transparent armour – mechanical properties, ballistic performance and ageing behaviour
(2023-08-14)Polycarbonate is an engineering plastic that is frequently used as a component in, or as a stand-alone, transparent armour for many military applications. One important application of polycarbonate is in transparent armour ... -
Population Based Routing in LEO Satellite Networks
(2022-06-26)Packet switching in a Low Earth Orbit (LEO) satellite network may calculate the best traffic route through the less populated areas of the planet, in order to avoid relaying through the busiest satellites. A number of ideas ... -
Possible effects of the 2003 invasion of Iraq on the nuclear programs in Iran, North Korea and Libya
(2014-01-09)In 2003 the nuclear programs in North Korea, Iran and Libya all took a radical new turn; North Korea left the Treaty on the Non-Proliferation of Nuclear Weapons; Iran halted parts of its nuclear program and signed the ... -
Post-blast explosive residue-a review of formation and dispersion theories and experimental research
(2014)The presence of undetonated explosive residues following high order detonations is not uncommon, however the mechanism of their formation, or survival, is unknown. The existence of these residues impacts on various scenarios, ... -
Postnatal exposure to PCB 153 and PCB 180, but not to PCB 52, produces changes in measures of attention, activity level and impulsivity in outbred male Wistar Kyoto rats
(2011)Background Polychlorinated biphenyls (PCBs) are a class of organic compounds that bioaccumulate due to their chemical stability and lipophilic properties. Humans are prenatally exposed via trans-placental transfer, ... -
The potential impact of 1-8 kHz active sonar on stocks of juvenile fish during sonar exercises
(2005)The mortality threshold for juvenile herring exposed to sonar signals is 180-190 dB (re 1μPa), and for other species even higher. This report analyses the potential impact of sonar transmissions on recruitment to important ...
