The SENSOTEK Synthetic Aperture Sonar - results from HUGIN AUV trials
(2007)FFI har et samarbeid med Kongsberg Maritime for utvikling av syntetisk aperture sonar (SAS) teknologi for HUGIN autonom undervannsfarkost (AUV). Som en del av dette samarbeidet er en bredbåndet, bredstrålet interferometrisk ... -
Sentrale regler for kontrahering i prosjekters tidligfase : Forsvarets anskaffelser
(2007)Denne rapporten handler om hvordan man innenfor offentlige rammer og regler kan gjennomføre gode og effektive prosjekter som i sin natur er komplekse. Utgangspunktet er Forsvarets anskaffelser og behov. Vårt hovedspørsmål ... -
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 ... -
Service decomposition using the NATO C3 Taxonomy - case studies
(2021-01-29)NATO introduced the Connected Forces Initiative at the 2012 Chicago summit with the aim to enhance allied interoperability and readiness in order to strengthen the combat power of the alliance. One of the aspects highlighted ... -
Service discovery in the soldier networking environment
(2008)Mobile Ad-hoc Network (MANET) technology have proved to be a very useful tool for meeting the tactical battlefield communication requirements and is crucial in the future soldier networking environment. Automatic discovery ... -
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 detection probability analysis for a possible long-range AIS system
(2005)There is an increasing requirement for global tracking of sea-going vessels. This report investigates the possibility of optimising the existing Universal Shipborne Automatic Identification System (AIS) for long-range AIS ... -
Ship detection using high resolution satellite imagery and space-based AIS
(2011-12-15)Denne rapporten presenterer en test utført i Malangen nær Tromsø i Nord-Norge i september 2010. Høyoppløselige Syntetisk Aperture Radar-bilder (SAR) fra RADARSAT-2 har blitt brukt for å analysere hvordan SAR-bilder og ... -
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 ... -
Shock attenuation by porous materials
(2015-03-24)Shock waves from explosions can do great damage to humans, buildings and other structures. Protective measures may therefore be useful to attenuate the effect of the shock waves. Porous materials have traditionally been ... -
Shock attenuation experiments using a Hopkinson bar method : summary of experimental results
(2009)Close-in attenuation of the pressure wave from a detonation is desirable in several applications. Porous materials are often assumed to have good shock damping properties. In this report an experimental set-up using a ... -
Shock sensitivity testing of Octols
(2008)Octol 60/40 and 70/30 (HMX/TNT) have been tested with regard to shock sensitivity in Intermediate Scale GAP test. Both compositions were cast filled into the test tubes. An average density of 98.1% of TMD was obtained ... -
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 ... -
