Range-dependent geoacoustic inversion using the parabolic equation and genetic algorithms - application to GAIT test cases
(2006)Rapid in-situ assessment of sonar conditions in shallow water is an area of interest for military applications. The goal is through-the-sensor techniques that collect acoustic data from sonar, infer the relevant ocean ... -
Rapid Autodyn-3D penetration simulations using a virtual target
(2002)By taking advantage of the possibilities for developing user subroutines in Autodyn-3D, we implement a method that uses a virtual target to decrease runtimes for 3D problems by several orders of magnitude. The new method ... -
Rapid detection of gastrointestinal pathogens in water using the FilmArray® system
(2018-11-08)We investigated the capabilities of the FilmArray gastrointestinal panel to detect bacterial and parasitical agents in contaminated river water. The FilmArray system is based upon molecular methods using a nested multiplex ... -
Rapid Environmental Assessment (REA) for øvelse Cold Response 2012
(2012-09-03)Informasjon om miljøet man opererer i er kritisk for gjennomføringen av en militær operasjon. Rapid Environmental Assesment (REA) er et NATO-konsept for å samle inn, prosessere og videreformidle miljøinformasjon til ... -
Rapid Identification of Bacillus anthracis Spores in Suspicious Powder Samples by Using Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS)
(2013)Rapid and reliable identification of Bacillus anthracis spores in suspicious powders is important to mitigate the safety risks and economic burdens associated with such incidents. The aim of this study was to develop and ... -
The Rapidly Exploring Random Tree Funnel Algorithm
(2022-03-17)This paper shows the feasibility of combining robust motion primitives generated through the Sums Of Squares programming theory with a discrete Rapidly exploring Random Tree algorithm. The generated robust motion ... -
Rate table tests of low-cost inertial measurement units
(2014-11-13)This report gives a summary of the results of a series of tests of low cost inertial measurement units conducted at FFI in late 2012. The units were all based on microelectromechanical technology (MEMS) and included the ... -
A Reactive Collision Avoidance Algorithm for Vehicles withUnderactuated Dynamics
(2017)This paper presents a reactive collision avoidance algorithm, which avoids both static and moving obstacles by keeping a constant avoidance angle between the vehicle velocity vector and the obstacle. In particular, we ... -
Reactive Collision Avoidance for Nonholonomic Vehicles in Dynamic Environments with Obstacles of Arbitrary Shape
(2021-11-01)Over the recent years, there has been an increasing interest in autonomous systems. Consequently, the problem of avoiding static and dynamic obstacles without human interference has gained a lot of attention. Avoiding ... -
Reactive Collision Avoidance for Underactuated Surface Vehicles using the Collision Cone Concept
(2021-08)Avoiding collisions is a crucial task for autonomous systems. Many strategies for avoiding obstacles have been proposed, yet the problem of having underactuated dynamics is rarely addressed in previous studies of collision ... -
Reaktordrevne fartøyer og deres eventuelle kjernevåpen : en oversikt ved årsskiftet 2015/2016
(2016-08-29)En rekke stater har reaktordrevne fartøyer. De fleste av disse har strategisk og taktisk militær betydning, og i tillegg representerer de en ulykkesrisiko som igjen kan føre til spredning av radioaktiv forurensning i ... -
Real-time anomaly detection in hyperspectral images using multivariate normal mixture models and GPU processing
(2009)Hyperspectral imaging, which records a detailed spectrum of light arriving in each pixel, has many potential uses in remote sensing as well as other application areas. Practical applications will typically require real-time ... -
Real-time georeferencing for an airborne hyperspectral imaging system
(2011)The paper describes the georeferencing part of an airborne hyperspectral imaging system based on pushbroom scanning. Using ray-tracing methods from computer graphics and a highly efficient representation of the digital ... -
Real-time PCR and NASBA for rapid and sensitive detection of Vibrio cholerae in ballast water
(2012)Transport of ballast water is one major factor in the transmission of aquatic organisms, including pathogenic bacteria. The IMO-guidelines of the Convention for the Control and Management of Ships’ Ballast Water and ... -
Realising benefits in public IT projects: A multiple case study
(2022-12-13)Information Technology (IT) investments in the public sector are large, and it is essential that they lead to benefits for the organisations themselves and wider society. While there is evidence suggesting a positive ... -
Realkostnadsvekst i Forsvaret - betydningen av innsatsfaktorenes substitusjonsmulighet
(2012-03-01)FFI har gjennom mange år studert fenomenet enhetskostnadsvekst (EKV) og dets betydning for Forsvarets langtidsplanlegging. Disse analysene kan deles inn i henholdsvis kvantitative analyser, med fokus på historisk utvikling, ... -
Realkostnadsvekst i offentlig sektor - teoretisk fundament og konsekvenser for Forsvarets langtidsplanlegging
(2011-02-20)I Forsvarets langtidsplanlegging er det behov for å beregne fremtidige kostnader for alternative strukturer og operasjonskonsepter. Derfor er det avgjørende å vite hvordan kostnadene for Forsvarets ulike ressurser endrer ...
