Overvåking av tungmetallforurensning ved Forsvarets destruksjonsanlegg for ammunisjon i Lærdal kommune - resultater for 2019
(2020-11-12)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 ... -
Kritiske samfunnsfunksjoner – en framgangsmåte for status- og tilstandsvurderinger
(2020-11-13)Samfunnssikkerhet er definert som «samfunnets evne til å verne seg mot og håndtere hendelser som truer grunnleggende verdier og funksjoner og setter liv og helse i fare» i Meld. St. 10 (2016–2017). Målet med samfunnssi ... -
Vurdering av nye og gamle probitfunksjoner for innånding av akutt giftige stoffer
(2020-11-10)Probitfunksjoner benyttes som en del av en kvantitativ risikoanalyse (QRA) av farlige hendelser, som for eksempel akutte utslipp av farlige stoffer. En probitfunksjon beskriver forholdet mellom konsentrasjonen av det ... -
Personell og kompetanse i Forsvarets materiellinvesteringsprosjekter - analyser av personellbehovet i bemanningsplaner
(2020-10-22)Forsvarsmateriell (FMA) har ansvar for å fremskaffe, forvalte og avhende materiell i forsvarssektoren på en ressurseffektiv måte, og innen fremskaffelse er gjennomføringen av investeringsprosjekter en sentral aktivitet. ... -
Norwegian long-term defence analysis - a scenario- and capability-based approach
(2020-10-21)The Norwegian Defence Research Establishment (FFI) supports the political and military leadership of Norwegian defence in their long-term defence planning. In this report, we describe and review the method FFI uses to ... -
Compressed sensing og sparse rekonstruksjon i radarsammenheng
(2020-09-25)Denne rapporten gir en kort gjennomgang av de viktigste prinsippene bak compressed sensing og vurderer noen mulige anvendelser i radarsammenheng. Compressed sensing er en metodikk som kan anvendes for å samle inn og ... -
Helhetlig helse- og miljørisikovurdering av eksplosivforurensninger i Demoleringsfeltet i Svånådalen, Hjerkinn
(2014-06-27)Det er tidligere påvist meget høye konsentrasjoner av eksplosiver i grunnen på demoleringsplassen i Svånådalen i Hjerkinn skyte- og øvingsfelt. Det ble derfor gjort en risikovurdering av dette området med hensyn på mennesker, ... -
The use of Atlantic hagfish (Myxine glutinosa) as a bioindicator species for studies on effects of dumped chemical warfare agents in the Skagerrak. 2. Biochemical biomarkers
(2020)The sea bottom of the Skagerrak Strait (North Sea) contains munitions loaded with chemical warfare agents (CWA), mostly stored in shipwrecks scuttled intentionally after the end of the World War II. The munition shells ... -
The use of Atlantic hagfish (Myxine glutinosa) as a bioindicator for studies on effect of dumped chemical warfare agents in Skagerrak. 1: Liver histopathology.
(2020)Within the framework of the international project DAIMON (Decision Aid for Marine Munitions), the impact of dumped chemical munitions on fish health was investigated. The Skagerrak Straight (North Sea, at 600 m depth) ... -
Training of Neural Network Target Detectors Mentored by SO-CFAR
(2020)A desirable objective in radar detection theory is the ability to detect and recognize targets in intricate scenarios such as in the presence of clutter or multiple closely spaced targets. Herein we propose the use of ... -
A 3D reactive collision avoidance algorithm for underactuated underwater vehicles
(2020-02-28)Avoiding collisions is an essential goal of the control system of autonomous vehicles. This paper presents a reactive algorithm for avoiding obstacles in a three‐dimensional space, and shows how the algorithm can be applied ... -
Leakage rate of the nerve agent tabun from sea-dumped munition
(2020-10)The leakage rate of nerve agents from corroded munition on the sea floor has been estimated by using table sugar as a simulant for the nerve agent tabun. Laboratory experiments were conducted with a full-size model of a ... -
Computational fluid dynamics simulations of local wind in large urban areas
(2020-09-29)The present report details the methodology and parameters used for high-fidelity computational fluid dynamics (CFD) simulations of wind in large urban areas. In particular, a 150 km2 area of Oslo is used as an example, ... -
Improved Passivation Effect Due to Controlled Smoothing of the CdTe-HgCdTe Interface Gradient by Thermal Annealing
(2019-07-11)HgCdTe films grown by liquid phase epitaxy were passivated with CdTe grown by molecular beam epitaxy. A series of annealing tests with different temperatures and durations were then carried out in order to reach a two-fold ... -
Assessment of intake of copper and lead by sheep grazing on a shooting range for small arms: a case study.
(2018-04-11)The Norwegian Armed Forces’ shooting ranges contain contamination by metals such as lead (Pb) and copper (Cu) and are often used as grazing pastures for livestock. To determine whether the sheep were at risk from grazing ... -
