Øke bemanningen i Forsvaret i dramatisk nedgangskonjunktur? En samfunnsøkonomisk vurdering
(2021)Koronapandemien har resultert i kraftige fall i etterspørsel, produksjon og sysselsetting i Norge og internasjonalt. Arbeidsledigheten i Norge er nå unormalt høy. Arbeidsøkonomisk litteratur har påvist at det er kostbart ... -
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 ... -
Multimodal change monitoring using multitemporal satellite images
(2021-09-12)The main objective of this study is to monitor the land infrastructure growth over a period of time using multimodality of remote sensing satellite images. In this project unsupervised change detection analysis using ITPCA ... -
Framtidas heimevern
(2021-09-27)HVORDAN BLIR FRAMTIDAS HEIMEVERN? Forsvarets forskningsinstitutt har på oppdrag fra Forsvarsdepartementet og Heimevernsstaben studert hvilken innretning Heimevernet bør ha i framtida. Det har vi gjort gjennom et treårig ... -
Single-point structure tensors in turbulent channel flows with smooth and wavy walls
(2019-10-06)A long-standing problem in turbulence modeling is that the Reynolds stress tensor alone is not necessarily sufficient to characterize the transient and nonequilibrium behaviors of turbulence under arbitrary mean deformation ... -
Forsvarsindustrien i Norge – statistikk 2020
(2021-09-10)Statistikken for 2020 viser at utvalget av norske forsvarsvirksomheter leverer ca.17 % av Forsvarets totale materiellinvesteringer. Forsvarsindustrien i Norge rapporterer en vekst i forsvarsrelatert omsetning på 20 % fra ... -
Påvirkes fisk og skalldyr av dumpet ammunisjon? – en undersøkelse i fire dumpefelt for krigsetterlatenskaper
(2021-09-09)FFI har undersøkt innhold av ammunisjonsrelaterte stoffer i fisk og skalldyr fanget i dumpefelt for ammunisjon, for å kartlegge opptak og risiko ved konsum. Det er gjort fangst av biota i Malangen, Skjerstadfjorden, ... -

(2021-09-14)This report is based on open sources and provides an overview of the current status and recent developments in the nuclear weapons arsenals of the world’s nine nuclear-weapon possessing states. The brief sections on each ... -
Military strategic aspects of Nordic security environment changes –identifying common Nordic strategic challenges
(2021-08-18)The study compares the strategic military challenges of the Nordic countries. The challenges identified by the Nordic states are remarkably similar – among the most similar of any given group in the world. First, the ... -
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 ... -
