A Review of Deep-Learning Methods for Change Detection in Multispectral Remote Sensing Images
(2023-04-16): Remote sensing is a tool of interest for a large variety of applications. It is becoming increasingly more useful with the growing amount of available remote sensing data. However, the large amount of data also leads ... -
Few-cycle pulse generation by double-stage hybrid multi-pass multi-plate nonlinear pulse compression
(2023-02-10)Few-cycle pulses present an essential tool to track ultrafast dynamics in matter and drive strong field effects. To address photon-hungry applications, high average power lasers are used which, however, cannot directly ... -
MIMO synthetic aperture sonar: Benefits and limitations
(2023-01-16)The use of Multiple Input Multiple Output (MIMO) orthogonally coded waveforms sharing the same bandwidth, has the potential to increase area coverage rate in synthetic aperture sonar (SAS). The disadvantage is cross-talk ... -
Mission command: A self-determination theory perspective
(2023-09-13)It is well documented that leadership behavior influences employees’ motivation. In particular are autonomy-supportive leadership styles associated with desirable outcomes through basic psychological needs satisfaction and ... -
Comprehensive quasi-steady force correlations for compressible flow through random particle suspensions
(2023-04-26)Models for quasi-steady drag, quasi-steady drag variation, and transverse forces for compressible flows through random, fixed, particle suspensions are presented. Correlations are formulated using drag force measurements ... -
Behavioural responses of wild, spawning Atlantic cod (Gadus morhua L.) to seismic airgun exposure
(2023-03-11)Seismic airgun surveys to map petroleum deposits in the seabed may impact behaviour of marine animals over large distances. Understanding whether fish spawning behaviour is affected by this anthropogenic noise source is ... -
Automatic Underway AUV Recovery Using a USV
(2022-09-12)The future Norwegian naval mine countermeasure (NMCM) capability includes unmanned, autonomous vessels. The Royal Norwegian Navy uses the Hugin autonomous underwater vehicle (AUV) in mine hunting operations. To facilitate ... -
Numerical modelling of short pulse shock initiation of ultrafine Hexanitrostilbene (HNS)
(2023-09-15)The study of short duration shock pulses is relevant in many high-energetic applications. One such application is the initiation of insensitive high explosives, often preferred as booster charges in military and civilian ... -
Overvåking av tungmetallforurensning ved Forsvarets destruksjonsanlegg for ammunisjon i Lærdal kommune – resultater for 2022
(2023-08-25)I henhold til avtale med Forsvarets logistikkorganisasjon (FLO) foretar Forsvarets forskningsinstitutt (FFI) kjemisk analyse og vurdering av overvåkningsprøver som blir tatt ved Forsvarets destruksjonsanlegg for ammunisjon ... -
FIST skal sikre informasjonsdeling
(2023-09)FIST er et flernasjonalt forskningssamarbeid mellom Norge, Tyskland og USA. Formålet er å utvikle, teste og demonstrere teknologier og metoder som gjør det mulig å dele informasjon sikkert og effektivt mellom militære ... -
Påvirkning og robusthet på sosiale medier –resultater og erfaringer fra piloteksperiment
(2023-01-27)Uønsket og fiendtlig påvirkning gjennom digitale medier representerer en sentral trussel mot norsk sikkerhet ifølge EOS (etterretnings-, overvåkings- og sikkerhets)-tjenestene. Mer kunnskap om de psykologiske faktorene som ... -
Dekning, rekkevidde og kapasitet for et 5G-radiosystem
(2023-09-06)Allerede i dag benytter Forsvaret kommersiell mobilteknologi, og det er mange grunner til å tro at militær bruk av mobilteknologi vil øke i framtiden. Femtegenerasjons mobilteknologi (5G) kan derfor bli en vesentlig ... -
Sluttårsaker blant militært personell i Forsvaret i 2021 og 2022
(2023-08-21)Forsvaret har et mål om å beholde mer personell lenger. For å nå dette målet er det viktig at de forstår hvorfor personellet slutter før ansettelsesforholdet utløper. Dette gjelder særlig for de yngste, som bare har vært ... -
Strain rate dependency and fragmentation pattern of expanding warheads
(2014-12-22)For the characterization of the behaviors of a metal material in events like expanding warheads, it is necessary to know its strength and ductility at high strain rates, around 104 e105 /s. The flyer plate impact testing ... -
Improving the decision-making basis by strengthening the risk assessments of unexploded ordnance and explosive remnants of war
(2023-01-15)For many countries, the legacy of armed conflict in the form of unexploded ordnance has a severe impact on society and daily life, as millions of tonnes of explosive remnants of war represent a grave threat to both the ... -
Introduction: Training is more important than technology (for performance in the cold)
(2023-07-27)After more than 50 years of studying soldiers in the cold, we are well past the phase of defining the unique problems; the research requirements are known but the solutions have been slow in coming. This requires iterative ... -
