(2022-01-13)Dette notatet inneholder histogrammer som viser fordelingen til alle avhengige og uavhengige variabler som ligger til grunn for de foreløpige resultatene fra FFIs prediksjonsturnering og sammenligningene av disse med ... -
Pragmatism and Purism in Jihadist Governance: The Islamic Emirate of Azawad Revisited
(2022-01-02)The Islamic Emirate established in northern Mali in 2012 was brought down less than a year later by a French military intervention, pro- voked by the Emirate’s belligerent posture. This article explains why the leaders of ... -
The First GAEN-Based COVID-19 Contact Tracing App in Norway Identifies 80% of Close Contacts in “Real Life” Scenarios
(2021-11-17)The coronavirus disease 2019 (COVID-19) response in most countries has relied on testing, isolation, contact tracing, and quarantine (TITQ), which is labor- and time-consuming. Therefore, several countries worldwide launched ... -
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 ... -
In situ performance prediction of a coherent acoustic modem in a reverberant environment
(2021-07-28)A channel sounding and communications experiment was performed in the Oslofjord, using eight bottom-mounted instrument units deployed in a network configuration. Five units were equipped with a software-defined 4–8-kHz ... -
Spectral characteristics of moist birch leaves and synthetic materials: experimental studies and evaluation of models
(2021-11-09)The optical depth of biomaterials and natural backgrounds varies with their environment and incoming light properties. Deciduous trees, for instance, have canopy thicknesses that vary significantly from one place to another. ... -
Stordata og avansert analyse – sluttrapport for FFI-prosjekt «Informasjonsintegrasjon for et moderne forsvar»
(2022-01-06)Stordata kan best forstås som et begrep heller enn en konkret teknologi eller familie av teknologier. I dette arbeidet karakteriseres stordata som data av forskjelligartet natur (variety), som kommer i store mengder ... -
Predicting scalar coupling constants via machine learning
(2021-12-22)Over the preceding decade, machine learning techniques have been successfully applied in several fields of research, including the prediction of chemical properties of atoms and molecules. Whereas conventional quantum ... -
Kildegrunnlag og metode i FFIs studier av russisk forsvarsøkonomi
(2021-12-21)I denne rapporten redegjør vi for kildegrunnlaget i FFIs studier av russisk forsvarsøkonomi. Rapporten inneholder en gjennomgang av sentrale primær- og sekundærkilder samt en diskusjon av kvaliteten på kildetilfanget og ... -
Algorithms for analysis of ballistic radar data
(2021-12-14)This report describes the algorithms used for processing ballistic radar data at the Norwegian Defence Research Establishment (FFI). A ballistic radar measures the velocity history of projectiles. This is used to determine ... -
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 ... -
Utilizing Zirconium MOF-functionalized fiber substrates prepared by molecular layer deposition (MLD) for toxic gas capture and chemical warfare agent degradation
(2021-09-12)Metal–organic frameworks (MOFs) are a class of porous organic-inorganic solids extensively explored for numerous applications owing to their catalytic activity and high surface area. In this work MOF thin films deposited in ... -
Overvåking av tungmetallforurensning ved Forsvarets destruksjonsanlegg for ammunisjon i Lærdal kommune – resultater for 2020
(2021-10-21)I Øyradalen sørøst for Lærdal sentrum ligger Forsvarets demoleringsfelt for ammunisjon. Dette området ble etablert i 1976 og har siden blitt benyttet av Forsvaret. For å overvåke konsentrasjonen av tungmetaller i dette ... -
Hvordan kan ny IKT gjøre Forsvaret bedre?
(2021-11-11)Norge står overfor en krevende sikkerhetspolitisk situasjon. Forsvaret spiller en avgjørende rolle for å skape sikkerhet for staten, befolkningen og samfunnet, og det er avgjørende at Forsvaret moderniseres og videreutvikles ... -
Spatial coherence of speckle for repeat-pass synthetic aperture sonar micronavigation
(2021-03-31)Accurate positioning of autonomous underwater vehicles is a major challenge. The long-term drift is problematic if global position updates are not available, and for applications such as repeat-pass interferometry and ... -
A neural network framework for binary classification of radar detections.
(2021-09-17)A desired objective in radar target detection is to satisfy two very contradictory requirements: offer a high probability of detection with a low false alarm rate. In this paper, we propose the utilization of artificial ... -
