Destined for deadlock? Russia, Ukraine, and the unfulfilled Minsk agreements
(2020-01-27)Bringing peace, security, and stability to the war-torn region of Donbas has proven to be a challenging — some would say near-impossible — task. The "Minsk II" agreement, signed in February 2015, was supposed to put an end ... -
Particle-resolved simulations of shock-induced flow through particle clouds at different Reynolds numbers
(2020-01-27)This study investigates the Reynolds-number dependence of shock-induced flow through stationary particle clouds at 10% volume fraction, using ensemble-averaged results from three-dimensional particle-resolved large eddy ... -
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 ... -
When Insularity Becomes a Problem: The Literature on Jihadism in Jordan
(2020-02-07)This article offers a review of the literature on Jordanian jihadism. While excellent work has been done, particularly on the phenomenon’s history and ideologues such as Abu Muhammad al-Maqdisi, several topics remain ... -
Federating Tactical Edge Networks:Ways to Improve Connectivity, Security, and Network Efficiency in Tactical Heterogeneous Networks
(2020-02-14)This article elaborates on security and routing architectures for mobile tactical heterogeneous networks. It explores challenges and opportunities, and highlights the characteristics of these types of networks and their ... -
An application of a combined framework to set the future direction of the Norwegian Home Guard
(2020-02-17)In 2017, the Norwegian Ministry of Defence and the Norwegian Home Guard commissioned a research project to help set a future identity and direction for the reserve-based Home Guard. Using a combination of frameworks, we ... -
A 3D reactive collision avoidance algorithm for underactuated underwater vehicles
(2020-02-28)Avoiding collisions is an essential goal of the control system of autonomous vehicles. This paper presents a reactive algorithm for avoiding obstacles in a three‐dimensional space, and shows how the algorithm can be applied ... -
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 ... -
The Emergence of Russian Private Military Companies: A New Tool of Clandestine Warfare
(2020-03-19)In recent years, the Russian private security and military company (PMSC) industry has evolved to serve the needs of both business clients as well as governments. Thus far, the ties between the Kremlin and the Russian PMSC ... -
Scaling Behavior of Quasi-One-Dimensional Vortex Avalanches in Superconducting Films
(2020-03-27)Scaling behaviour of dynamically driven vortex avalanches in superconducting YBa2Cu3O7−δ films deposited on tilted crystalline substrates has been observed using quantitative magneto-optical imaging. Two films with different ... -
When the noise goes on: received sound energy predicts sperm whale responses to both intermittent and continuous navy sonar
(2020-04-08)Anthropogenic noise sources range from intermittent to continuous, with seismic and navy sonar technology moving towards near-continuous transmissions. Continuous active sonar (CAS) may be used at a lower amplitude than ... -
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 ... -
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 ... -
A Monte Carlo approach to evaluate stray laser energy from the F-35 Lightning II
(2020-04-23)The F-35 Lightning II has a powerful combat laser designator operating at a wavelength and energy levels that are damaging to the human eye at a pulse level. Due to the faceted design of the Electro Optical Targeting System ... -
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 ... -
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 ... -
