Design of an initial LLC Data Protocol for the NBWF Simulator
(2012-03-21)NATO has an ongoing activity with the objective to develop a narrowband waveform (NBWF) standard. This is a single-channel mobile ad-hoc network (MANET) which shall serve voice traffic and data traffic over a 25 kHz radio ... -
The design of an initial NBWF network simulator
(2008)Dette dokumentet er en leveranse fra modellerings- og simuleringsaktiviteten under TIPPER-prosjektet. Prosjektet deltar aktivt i et standardiseringsarbeid i NATO som skal ta fram en smalbånds bølgeformstandard. Hensikten ... -
Design og implementasjon av FFI GCS - kontrollstasjon for ubemannede systemer
(2016-02-26)Formålet med denne rapporten er å dokumentere og gjøre kjent en egenutviklet kontrollstasjon for ubemannede systemer, tatt frem gjennom prosjektet 1359 «Teknologi for fremtidens UAS». Motivasjonen for å utvikle en egen ... -
Desinfeksjon og gjenbruk av åndedrettsvern (filtrerende halvmasker) - litteratursammenstilling
(2020-05-05)Åndedrettsvern, som filtrerende halvmasker, benyttes i helsevesenet for å beskytte brukeren mot smittestoffer. Maskene må ha god tetting mot ansiktet og et velfungerende filtermateriale for å virke optimalt. De er ... -
Destined for deadlock? Russia, Ukraine, and the unfulfilled Minsk agreements
(2020-01-27)Bringing peace, security, and stability to the war-torn region of Donbas has proven to be a challenging — some would say near-impossible — task. The "Minsk II" agreement, signed in February 2015, was supposed to put an end ... -
Det grønne forsvaret?
(2019-11-13)DET ER PÅ TIDE Å TA NESTE STEG Bladet du nå holder i hendene skiller seg fra andre FFI-rapporter. Det er ikke sluttresultatet av ett bestemt forskningsprosjekt. Denne utgaven av VITEN er resultat av flere års forskning ... -
Det slaviske triangelet - en studie av Russlands utenriks- og sikkerhetspolitikk i forhold til Hviterussland og Ukraina
(2000)This report gives an analysis of how Russian foreign policy ambitions towards Ukraine and Belarus changed during the period from 1991 to 1997, and by what means Russia conducted her foreign policy towards the two countries. ... -
Detection metrics and ship [D]RI
(2018)Well-known detection metrics based on Johnson criteria or Target Task Performance (TTP) models were developed for land-based targets [1,2]. In this paper we investigate how (whether) we can apply these metrics to especially ... -
Detection of forest clear-cuts with shuttle radar topography mission (SRTM) and tandem-X InSAR data
(2013)The aim of this study was to determine whether forest clear-cuts during 2000–2011 could be detected as a decrease in surface height by combining Digital Surface Models (DSMs) from the Shuttle Radar Topography Mission ... -
Detection of Legionella pneumophila in a biological treatment plant by co-cultivatiobn with Acanthamoeba castellanii
(2014)Legionella pneumophila was identified in the aeration ponds of a biological wastewater treatment plant at the pulp and paper industry Borregaard, Sarpsborg, Norway. After 3 outbreaks of Legionaires’ disease reported in ... -
Detection of military objects in LADAR images
(2008)This report describes different techniques for preprocessing, segmentation, and detection of vehicle sized objects in LADAR images. Five preprocessing strategies are presented; 1) Median filtering, 2) Two 1-D median ... -
Detection of Point Scatterers in Medical Ultrasound
(2021-11-19)We present an overview of the detection of point scatterers in ultrasound images and suggest strategies for evaluating and measuring the detection performance. We use synthetic aperture Field II simulations of a point ... -
Detection performance for Incoherent Range Walk Compensation
(2014-11-24)FFI supports the Royal Norwegian Air Force in their acquisition of new air surveillance sensors. Improved detection performance on low observable targets may be obtained by increasing the radar dwell time on target. For ... -
Detection: how many pixels are required?
(2020-09-23)In this work, we studied how detection range of a small target changes as a function of the number of defined target pixels. The intuitively simplest method to look for a target in IR images is to look for the “hottest” ... -
Deteksjon av eksplosivrester i felt ved hjelp av hyperspektral avbildning
(2009)Der er kjent at det i Forsvarets skytefelt ligger rester av eksplosiver, noe som hovedsakelig skyldes ufullstendig detonasjon av ammunisjon. Disse restene er vanskelige å finne, men er ansett å være et miljøproblem blant ... -
Determination of chemical warfare agents in water samples by solid phase microextraction and GC-FID
(2007)The Norwegian Defence Research Establishment (FFI) is presently developing a mobile laboratory for the identification of chemical warfare agents (CWA) and related compounds. The laboratory will be used in the field, and ... -
Determination of critical diameter for DPX-6
(2006)M72 LAW (Light Antiarmour Weapon) has been redesigned with a new warhead for urban warfare. The new warhead is designed for combat of light buildings and therefore needs an explosive filling that is optimized for this ... -
Determination of detonation pressure and velocity for RDX/GAP propellant
(2017-03-13)Detonation velocity and detonation pressure have been determined for the solid propellant D- 07, a RDX/GAP propellant produced by Nammo Raufoss. Three firings, two with test item diameter 35.6+1 mm and one with diameter ... -
