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 ... -
Imaging ground sensor system OPAK
(2003-09-18)Architecture and technology of imaging intrusion detection sensor OPAK are presented. Applications and desired features for IDS and UGS are compared. Started developments of OPAK towards an unattended ground sensor system ... -
Characterization of (111)B and (211)B CdZnTe Substrates for HgCdTe Growth
(2019-06-13)We have studied state-of-the-art CdZnTe (211)B and (111)B substrates and compared them to each other and to substrates from an alternative vendor. The CdZnTe surface has been characterized both as-received and after growth ... -
Classification based on fast and robust approximations to order statistics
(2020-04-22)A test system with four cameras in the infrared and visual spectra is under development at FFI (The Norwegian Defence Research Establishment). The system may be mounted on a jet aircraft or may be used in a land-based ... -
Robustness of adversarial camouflage (AC) for naval vessels
(2020-04-24)Different types of imaging sensors are frequently employed for detection, tracking and classification of naval vessels. A number of countermeasure techniques are currently employed against such sensors, and with the advent ... -
Investigating robustness of adversarial camouflage (AC) fornaval vessels
(2020-09-20)The use of camouflage is widespread in the biological domain, and has also been used extensively by armed forces around the world in order to make visual detection and classification of objects of military interest ... -
Studying the effect of source proximity in sperm whales and continous sonar in pilot whales using operational sonars - the 3S-2019-OPS cruise report
(2020-07)The 3S project is an international collaborative effort with the aim to investigate behavioral reactions of cetaceans to naval sonar signals. The objectives of the third phase of the project are to investigate if exposure ... -
Comparison of synthetic aperture sonar images and optical images of UXOs from the Skagerrak chemical munitions dumpsite
(2019-11-28)After World War II chemical munitions were loaded onto large ships and sunk in the Skagerrak Strait in the Norwegian trench, in deep waters between Norway and Denmark. In collaboration with the Norwegian Coastal Administration, ... -
Interferometric Synthetic Aperture Sonar in Pipeline Inspection
(2010-10-14)Accurate and reliable inspection of subsea pipelinestraditionally requires the use of multiple sensors, which againhave different requirements for range and geometry. This makespipeline inspection a time consuming and ... -
SMART II: Android apps, cloud computing and mobile device management as enablers for efficient operations
(2019-11-25)"SMART" { pervasive situational awareness at the individual soldier level { was a Concept Development and Experimentation (CD&E) project carried out in Norway during 2016. The concept being tested was the use of smart ... -
Experimental Evaluation of Named Data Networking (NDN) in Tactical Environments
(2020-03-05)Tactical edge networks represent a uniquely challenging environment from the communications perspective, due to their limited bandwidth and high node mobility. Several middleware communication solutions have been proposed ... -
Motivasjon er ferskvare - en feltstudie på forventninger og motivasjon for tjeneste blant rekrutter på KNM Harald Haarfagre
(2020-08-20)Utsagnet som tittelen viser til – at motivasjon er ferskvare – går ofte igjen blant militært personell. Det betyr at motivasjon for tjeneste ofte er i endring og må holdes ved like. Ulike faktorer spiller inn for å motivere ... -
Teknologiske trender – mulige konsekvenser for Luftforsvaret
(2020-08-19)Denne rapporten ser på hvordan ny teknologi vil kunne påvirke Luftforsvaret i løpet av de neste 10–40 år. Rapporten kommer med antagelser og vurderinger basert på observerte trender og analytiske slutninger. Rapporten ... -
