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 ...
Redrawing borders, reshaping orders: Russia’s quest for dominance in the Black Sea region
(2021-01-04)
Since Russia’s annexation of Crimea in March 2014, severe limitations have been placed on Ukraine’s coastal state rights and navigational freedoms in the Black and Azov Seas and the Kerch Strait. The "Kerch Strait clash" ...
Generative Adversarial Immitation Learning for Steering an Unmanned Surface Vehicle
(2020-02)
The task of obstacle avoidance using maritime vessels, such as Unmanned Surface Vehicles (USV), has traditionally been solved using specialized modules that are designed and optimized separately. However, this approach ...
A study of the Browning M2 Quick Change Barrel and problems experienced in the Norwegian Armed Forces
(2021-03-09)
Norway has used the Browning M2 heavy machine gun for decades. The first guns were US weapons
given to us through the Mutual Defence Assistance Program. They were M2 Heavy Barrel (HB)
versions. All weapons were converted ...
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 ...
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. ...
Vehicle Safety of the Velocity Obstacle Algorithm
(2021-01)
This paper presents a mathematical analysis of the velocity obstacle algorithm applied to a nonholonomic vehicle for avoiding a moving obstacle in the plane. The velocity obstacle algorithm can be used for local navigation ...
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 ...
A2/AD and the missile threat - systems, countermeasures and models
(2021-03-12)
In this report we discuss the (relatively) novel military term A2/AD, which is an acronym for Anti-
Access/Area Denial. We cover both general aspects related to how the term should be
understood, Russian A2/AD capabilities ...
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 ...
