Hydrodynamical simulations in FLUENT
(2010)A methodology for hydrodynamical simulations in FLUENT is described. The current application is the computational fluid dynamics analyses of two- and three-dimensional wings conducted as part of an underwater towing ... -
Sound propagation in regions of variable oceanography - a summary of student work at NTNU
(2010)Two ray tracing programs, Lybin and Ray5, have been used in student projects at NTNU to study wave propagation in range dependent environments. For a given set of sound speed profiles obtained during a FFI measuring ... -
Analyses of the geolocation accuracy that can be obtained from shipborne sensors by use of time difference of arrival (TDOA), scanphase, and angle of arrival (AOA) measurements
(2010)We have performed a theoretical study of the geolocation accuracy that can be obtained from shipborne sensors by use of the localization methods: 1) time difference of arrival (TDOA), 2) scanphase, and 3) angle of arrival ... -
Effects of contamination of water with white phosphorus on drinking behavior in sheep
(2010)White phosphorus (WP) is a toxic contaminant found in many military training areas. Wild and domestic herbivores may be exposed to WP through drinking contaminated water. Knowledge of how animals react towards WP is important ... -
Effects of heavy metals from outdoor shooting ranges on aquatic organisms
(2010)Metals deposited in shooting ranges (Pb, Zn, Cu and Sb) can affect fish health, fish populations and fish communities through a wide spectrum of mechanisms. In the current report the literature on the mechanisms of metal ... -
Semantic wiki - collaboration, semantics & semi-structured knowledge
(2010)Wikis are collaboration tools and characteristic examples of Web 2.0 utilisation of technology. Users participate to generate content and maintain the quality of information within the wiki. Information is contained in ... -
Effects of contamination of forage with explosives on feeding behaviour in sheep
(2010)The common military explosives TNT, RDX and HMX are distributed in many military training areas, and are thus encountered by large herbivores. We present the first scientific study of large herbivores’ voluntary intake of ... -
Næringsstrategisk vurdering knyttet til konseptuell løsning for UVB-kapasitet etter 2020
(2010)I prosjekt 1094 Støtte til utarbeidelse av konseptuell løsing for framtidig undervannsbåtkapabilitet har FFI gjort en næringsstrategisk vurdering av de konseptuelle løsningene. Alternativene til undervannsbåt innebærer nye ... -
LYBIN 6.0 : test report
(2010)The acoustic ray trace model LYBIN is a well established and frequently used sonar prediction model owned by the Norwegian Defence Logistic Organisation. The model is used aboard navy vessels as well as in training situations ... -

(2010)Dette dokumentet presenterer en oversikt over litteraturen innen feltet medisinsk radar, med hovedfokus p˚a hjerteslag- og pustdeteksjon, ultrabredb˚ands (UWB) medisinsk radar og avbildning i medisinsk radar. Først blir ... -
The Taliban insurgency in Afghanistan - organization, leadership and worldview
(2010)The aim of this report is to get a better understanding of the Taliban movement and its role in the Afghan insurgency post-2001. The approach to this is three-fold: First, the report discusses the nature of the Afghan ... -
Langsiktig planlegging i Forsvaret - vitenskap i skjæringspunktet mellom politikk, byråkrati og kommandostyring
(2010)Rapporten handler om utviklingen av Forsvarets langtidsplanlegging fra tidlig på 1970-tallet og fram mot år 2000. Den beskriver den prinsipielle tilnærmingen, hvordan planleggingsmetodikken ble utviklet og hvilken rolle ... -
Penetration analyses of protective suits and boots against jet fuel (JP-8)
(2000)Penetration analyses with jet fuel have been carried out on three different protective suits and one pair ofprotective boots. The analyses were performed with a single cell permeation system developed at Norwegian Defence ... -
Modeling the evaporation from a thin liquid surface beneath a turbulent boundary layer
(2010)The release and dispersion of toxic chemicals can cause a threat to military personnel and the population at large. In order to develop and implement appropriate protective capabilities and plan mitigating measures, ... -
Development of material models for semi-brittle materials like tungsten carbide
(2010)Tungsten carbide is a very special material that exhibits both brittle and ductile properties. While purely brittle and ductile materials in general are well understood, a theory for describing the properties of a hybrid ... -
Quality and equipment considerations in humanitarian demining
(2001)Simple arguments show that the commonly adopted UN requirement (99,6%) of mine clearance is too low for realistic situations if mines in a cleared region shall not be the leading cause of death also after demining. It ... -
