A socio-cognitive perspective on implementation and use of smart technology in the Norwegian home guard
(2019-11-25)
The Norwegian Defence Research Establishment (FFI) has developed a communications concept for the Norwegian home guard (HV). This concept, called ”SMART” due to the emphasis on smart technologies, has been
realized as a ...
Ship tracking results from state-of-the-art space-based AIS receiver systems for maritime surveillance
(2019-04-11)
Norway currently operates four satellites with Automatic Identification System (AIS) receivers. The first-generation satellites, AISSat-1 and AISSat-2, are equipped with a two-channel, single-antenna AIS receiver, while ...
Development and Calibration of a Low-Cost Radar Testbed Based on the Universal Software Radio Peripheral
(2019-12-01)
For a cognitive radar algorithm to be useful, it must run on radar hardware that is flexible. Typically, this has been viewed as requiring a software-defined radio. With the emergence of cheap, digital transceiver systems, ...
Fighting on behalf of the state—the issue of pro-government militia autonomy in the Donbas war
(2019-01-04)
This study investigates the degree of autonomy the Ukrainian volunteer battalions had from the regular forces during the war in Donbas. The findings indicate that the degree of autonomy was high and that in particular, ...
Det grønne forsvaret?
(2019-11-13)
DET ER PÅ TIDE Å TA NESTE STEG
Bladet du nå holder i hendene skiller seg fra andre FFI-rapporter. Det er ikke sluttresultatet
av ett bestemt forskningsprosjekt. Denne utgaven av VITEN er resultat av
flere års forskning ...
Predicting acoustic dose associated with marine mammal behavioural responses to sound as detected with fixed acoustic recorders and satellite tags
(2019-03-08)
To understand the consequences of underwater noise exposure for cetaceans, there is a need for assessments of behavioural responses over increased spatial and temporal scales. Bottom-moored acoustic recorders and satellite ...
Computational analysis of shock-induced flow through stationary particle clouds
(2019-03-22)
We investigate the shock-induced flow through random particle arrays using particle-resolved Large Eddy Simulations for different incident shock wave Mach numbers, particle volume fractions and particle sizes. We analyze ...
Collision Avoidance for Underactuated Marine Vehicles Using the Constant Avoidance Angle Algorithm
(2019-03-21)
Avoiding collisions is a crucial ability for unmanned vehicles. In this paper, we present the constant avoidance angle algorithm, a reactive method for collision avoidance. It can be used to avoid both static and moving ...
Estimating output mix effectiveness: An applied scenario approach for the Armed Forces
(2019)
The ability of public sector policy makers to prioritize has a huge impact on the effectiveness of public service provision. Public services can take the form of final outputs demanded by consumers or of intermediate outputs ...
Automating Event-B invariant proofs by rippling and proof patching
(2019-01-02)
The use of formal method techniques can contribute to the production of more reliable and dependable systems. However, a common bottleneck for industrial adoption of such techniques is the needs for interactive proofs. We ...
