Coherent high-speed acoustic communication inside a commercial atlantic salmon pen
(2020-06-07)
Fish telemetry is a potential method to monitor the well-being of farmed fish, where a reference group of fish are equipped with sensors tags that oversee their health and wirelessly transmit the data. Many fish must be ...
Variability of Gaseous Attenuation at Very Low Elevation Angle Slant Paths; Measurements and Modelling
(2020-07-08)
Gaseous attenuation variability for a 3.2° elevation angle satellite link operating at 20 GHz in the Norwegian Arctic is analyzed and compared with different models. At a very low elevation link like this one, gaseous ...
Fremtidig valutausikkerhet i kampflyanskaffelsen
(2021-05-18)
Stortinget vedtok i 2012 at Norge skulle anskaffe 52 kampfly av typen F-35 i perioden 2015 til
2025. Per oktober 2020 er det estimert at 85 prosent av de resterende anskaffelseskostnadene
vil påløpe i USD, noe som betyr ...
Energy deficit increases hepcidin and exacerbates declines in dietary iron absorption following strenuous physical activity: a randomized-controlled cross-over trial
(2020-11-12)
Background
Strenuous physical activity promotes inflammation and depletes muscle glycogen, which may increase the iron regulatory hormone hepcidin. Hepcidin reduces dietary iron absorption and may contribute to declines ...
Pathologic Blood Samples Tolerate Exposure to Vibration and High Turbulence in Simulated Drone Flights, but Plasma Samples Should be Centrifuged after Flight
(2021-01-30)
Objective. Most of the previous studies of drone transport of blood samples examined normal blood samples transported under tranquil air conditions. We studied the effects of 1- and 2-hour drone flights using random vibration ...
Evaluation of Two Path Following Controllers for an Ackermann Off-road Vehicle in Winter and Summer Conditions
(2021-04-02)
Off-road driving can be a challenging task with rapid changes in the driving conditions, terrain and vehicle behavior. For off-road autonomous vehicles, it is important to be robust to these changes, and parts of this ...
Data-Driven Autocalibration for Swath Sonars
(2020-12-20)
Sidelobes in swath sonar water column imagery can obscure targets of interest and create erroneous bottom detections. Differences between ideal and actual element responses limit the achievable sidelobe level for practical ...
NorSat-3 - Ship Surveillance with a Navigation Radar Detector
(Forsvarets forskningsinstitutt, 2021-04)
The NorSat-3 micro satellite will be launched into space during 2020 with a radar detector developed at the Norwegian Defence Research Establishment (FFI). It will provide improved surveillance capability of the shipping ...
NorSat-3 Skipsovervåking med navigasjonsradardetektor
(Forsvarets forskningsinstitutt, 2021-04)
I 2019 sendes mikrosatellitten NorSat-3 opp med en radardetektor utviklet ved Forsvarets forskningsinstitutt (FFI). Det skal gi bedre oversikt over skipstrafikken i norske farvann.
Operasjonalisering av Trekantmodellen 2.0 – anbefalinger for å øke innovasjonsevnen i forsvarssektoren
(2021-06-07)
Trekantmodellen har vært en effektiv innovasjons- og samarbeidsmodell for nasjonal teknologi- og materiellutvikling. Norge har også lyktes godt med en nisjebasert tilnærming til nasjonal teknologi- og industriutvikling ...
