Model and specification for analyzing the scalability of a public key infrastructure
(2009)Most security mechanisms rely on cryptographic keys and other secret values. Key management is crucial. A Public Key Infrastructure (PKI) is commonly established as a basis for key management. So far, PKIs have been ... -
A model for the burn velocity of tracers
(2006)In this report we perform a study of the burn velocity of tracer compositions. Both the burn velocity during flight and in static conditions is studied. In addition we present results for varying densities of the tracer ... -
A model for the viscous dissipation rate in stably stratified, sheared turbulence
(2013)A model for the turbulence dissipation rate in stably stratified shear turbulence is developed and validated. The functional dependence of the model is derived from first principles and it represents a conceptually new ... -
A model of internal ballistics properties in gun tubes
(2002)In this report a study of the pressure generated by burning of gunpowder in gun barrels has been carried out. Calculations using the model were compared with experimental results and with results from the standard ... -
A model study of the effective Young´s modulus for randomly distributed short-fiber composites
(2011-01-25)This report provides an overview of a set of macro-mechanical models for the effective Young’s modulus of short fiber composites. Various models are found in the literature with varying complexity, ranging from simple rule ... -
Modeling and Simulation as a Service infrastructure capabilities for discovery, composition and execution of simulation services
(2020-01-13)Modeling and Simulation as a Service (MSaaS) embodies the idea that simulations should be composed quickly for the task at hand from loosely coupled shared components, simulation services, in a cloud-based environment. ... -
Modeling Effectiveness of Gradual Increases in Source Level to Mitigate Effects of Sonar on Marine Mammals
(2014)Ramp-up or soft-start procedures (i.e., gradual increase in the source level) are used to mitigate the effect of sonar sound on marine mammals, although no one to date has tested whether ramp-up procedures are effective ... -
Modeling FMCW Radar for Subsurface Analysis
(2022-04-05)Determining subsurface properties through ground penetrating radar sounding can be challenging, especially in planetary exploration, where little is known about the terrain and additional observations are limited. Analysis ... -
MODELING IRON ABUNDANCE ENHANCEMENTS IN THE SLOW SOLAR WIND
(2011)We have studied the behavior of Fe ions in the slow solar wind, using a fluid model extending from the chromosphere to 1 AU. Emphasis is on elemental "pileup" in the corona, i.e., a region where the Fe density increases ... -
Modeling of a back-illuminated HgCdTe MWIR avalanche photodiode with alloy gradients
(2015)We present results from 2D Monte Carlo simulations of a mid-wave infrared (MWIR) back-illuminated planar n-on-p HgCdTe electron-initiated avalanche photodiode (e- APD). The main objective of this work has been to study the ... -
Modeling potential masking of echolocating sperm whales exposed to continuous 1-2 kHz naval sonar
(2021-04-30)Modern active sonar systems can (almost) continuously transmit and receive sound, which can lead to more masking of important sounds for marine mammals than conventional pulsed sonar systems transmitting at a much lower ... -
Modeling the behavior of a hierarchy of command agents with context-based reasoning
(2017)Context-based reasoning is a paradigm for modeling agent behavior that is based on the idea that humans only use a small portion of their knowledge at any given time. It was specially designed to represent human tactical ... -
Modeling the effect of random roughness on synthetic aperture sonar image statistics
(2022-09-02)A model has been developed to predict the effect of random seafloor roughness on synthetic aperture sonar (SAS) image statistics, based on the composite roughness approximation–a physical scattering model. The continuous ... -
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, ... -
Modeling underwater explosions: Extending Charles to FIVER
(2021-09-27)Modeling of explosions and implosions under water is important for design of vehicles and installations both under water and on the sea surface. There exists simple models, often in the form of empirical calibrations, for ... -
Modell for Beregning av Internasjonale Leveranser (MOBIL) - brukerveiledning og dokumentasjon
(2012-02-01)Denne rapporten dokumenterer metoden og forutsetningene i kostnadsberegningsmodellen MOBIL (Modell for Beregning av Internasjonale Leveranser). I tillegg til å dokumentere modellen er denne rapporten ment å fungere som ... -
Modell for flerscenario strukturoptimering - modellbeskrivelse
(2000)This report describes a model for cost-effective force structuring analysis using mathematical programming and optimization with game-theoretic utility measure. Force components including C2 and sensor/information are ... -
Modell for optimering av investeringsbeslutninger - resultater og anvendelse
(2011-05-10)FFI-prosjekt 1185 “Støtte til Forsvarsdepartementets langtidsplanlegging” (SIMFOR III) skal blant annet utnytte kvantitative analyser for å se på fremtidig utvikling av Forsvaret. Denne rapporten beskriver anvendelsen ... -
Modell for vurdering av operativ effekt av ulike AUV-konfigurasjoner
(2008)Denne rapporten er en delleveranse fra FFI-prosjekt 1040, AUV for kyststrid. Rapporten beskriver en modell for vurdering av operativ effekt av ulike konfigurasjoner av Autonomous Underwater Vehicle (AUV). Konseptutvikling ...
