Modeling and Simulation as a Service infrastructure capabilities for discovery, composition and execution of simulation services
(2020-01-13)Modeling and Simulation as a Service (MSaaS) embodies the idea that simulations should be composed quickly for the task at hand from loosely coupled shared components, simulation services, in a cloud-based environment. ... -
The Importance of Significant Others in Preventing Extremism: The Philosophy and Practice of the Swedish Tolerance Project
(2020)This article concerns a specific educational programme to reduce recruitment to racist and extreme organizations in Sweden. The programme is called the Tolerance Project, and it functions as an elective course offered to ... -
Challenges for Risk and Security Modelling in Enterprise Architecture
(2019-11-19)From our experience cooperating with the Norwegian Armed Forces, we outline two interconnected challenges for modelling risk and security in an enterprise architecture: (1) modelling what is protected and why it is protected ... -
The subway microbiome: Seasonal dynamics and direct comparison of air and surface bacterial communities
(2019-12-19)Background Mass transit environments, such as subways, are uniquely important for transmission of microbes among humans and built environments, and for their ability to spread pathogens and impact large numbers of people. ... -
Ship source level estimation and uncertainty quantification in shallow water via Bayesian marginalization
(2020-04-17)This paper applies a non-linear Bayesian marginalization approach to ship spectral source level estimation in shallow water with unknown seabed properties and uncertain source depth. The algorithm integrates the posterior ... -
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 ... -
Parameter selection in a fully adaptive tracking radar
(2020-04-27)A fully adaptive radar framework has been proposed in recent publications, and this paper will implement the framework for a tracking radar. A set of cost functions are developed to balance the performance cost of the track ... -
Simulation-supported wargaming for assessing force structures – methodology and best practices
(2021-02-26)When developing and assessing future force structures, wargaming is a key activity for gaining deeper insight and better understanding of the strengths and weaknesses of the force structures. Today, computer-based ... -
Laminar burning velocity of the dimethyl carbonate–air mixture formed by the Li-ion electrolyte solvent
(2020-08-21)If a Li-ion cell fails and the electrolyte leaks out into air, a flammable premixed gas cloud can be formed. The electrolyte combustion energy is 65–70% of the total energy content of the cell. The main objective of this ... -
Laser beam propagation through turbulence and adaptive optics for beam delivery improvement
(2015-10-08)We report results from numerical simulations of laser beam propagation through atmospheric turbulence. In particular, we study the statistical variations of the fractional beam energy hitting inside an optical aperture ... -
Specifying radiometric performance of hyperspectral and conventional cameras: A minimal set of independent characteristics
(2020)The radiometric performance of cameras is customarily characterized and specified in terms of component properties such as F-number and readout noise. This paper considers the camera as an integrated unit and derives ... -
Flamingo - a UAV for autonomy research
(2021-02-18)Flamingo is a four-motor unmanned aerial vehicle (UAV) developed at the Norwegian Defence Research Establishment (FFI) primarily for use in research on cooperating autonomous systems. The drone is designed with a focus ... -
