Campaigning with partners in the fourth age of SOF – the case of Norwegian – U.S. High North collaboration
(2024-10-11)Special Operations Forces (SOF) need to adapt to a new operating environment, characterized by competition, state-centric threats, and the use of conventional military power. The adaptation is a consequence of the existing ... -
Achieving Sub-Pixel Platform Accuracy With Pan-Tilt-Zoom Cameras in Uncertain Times
(2024-11-28)In this paper, we present a novel method for selfcalibrating a pan-tilt-zoom (PTZ) camera system model, specifically suited for long-range multi-target tracking with maneuvering low-cost PTZ cameras. Traditionally, such ... -
Effects of a 10-d Military Field Exercise on Body Composition, Physical Performance, and Muscle Cells in Men and Women
(2024-04)Purpose: To investigate the effects of a demanding military field exercise on physical performance, body composition and muscle cellular outcomes in men and women. Methods: Ten men (20.5 ± 0.5 years) and 8 women ... -
Direct hearing measurements in a baleen whale suggest ultrasonic sensitivity
(2024-11-21)Predicting and mitigating the impacts of anthropogenic ocean noise on marine animals is hindered by a lack of information on hearing in these species. We established a catch-and-release program to temporarily hold adolescent ... -
Fusion of passive and active electro-optical sensor data for enhanced scene understanding in challenging conditions
(2024-11-01)Passive electro-optical systems, such as visible and infrared light cameras, and active systems, such as ladar or LiDAR, can acquire detailed two- and three-dimensional images of a scene. This paper presents a sensor fusion ... -
On the importance of systems thinking in ERW (explosive remnants of war) risk management
(2024-01-02)One of the legacies of armed conflict is unexploded ordnance and abandoned ammunition. This legacy will, in many cases, have a severe impact on society and daily life, even for years or decades after hostilities have ... -
How to Understand Climate Change as a Threat Multiplier in the Arctic
(2024-11-18)The aim of this paper is to analyse climate change as a threat multiplier to security dilemmas in the Arctic. Security dilemmas occur when one state’s efforts to enhance its security provokes reactions from other states, ... -
Prevalence of musculoskeletal pain and associated factors among professional orchestra musicians in Norway
(2024-06-06)Background: Orchestra musicians have a high risk of experiencing musculoskeletal problems. These problems may lead to sleep and psychological disturbance. Objectives: This study investigated the occurrence of musculoskeletal ... -
War, diplomacy, and more war: why did the Minsk agreements fail?
(2024-11-15)Despite significant Western involvement, most notably by the leaders of Germany, France, and the Organization for Security and Co-operation in Europe (OSCE), the diplomatic efforts in 2014 and 2015 to forge a functioning ... -
Identification of complexes formed between sulphur mustards and arsenic-containing chemical warfare agents
(2024-10-22)Large quantities of toxic chemical warfare material, such as mixtures of sulphur mustard (HD) and arsenic-containing chemical warfare agents (As-CWAs) have been submerged in the Baltic Sea region after World War II. Little ... -
Numerical simulation of hydrogen dispersion in an open-ended rectangular channel
(2024-11-26)In this work, large-eddy simulations of hydrogen dispersion from turbulent subsonic hydrogen-gas emissions in a 5.8 × 0.9 × 0.8 m open-ended channel are described. Such numerical modeling of hydrogen-related processes ... -
A Modular Smart Ocean Observatory for Development of Sensors, Underwater Communication and Surveillance of Environmental Parameters
(2024-10-10)The rapid growth of marine industries has emphasized the focus on environmental impacts for all industries, as well as the influence of key environmental parameters on, for instance, offshore wind or aquaculture performance, ... -
Cold weather operations: Preventive strategies ina military context
(2024-10-23)Military cold weather operations (CWOs) introduce a range of challenges, including extremetemperatures, strong winds, difficult terrain, and exposure to snow, ice, and water. Personnelundertaking these missions face a ... -
Synthesis of nitroxyethylnitramine (NENA) plasticizers and dinitroxydiethylnitramine (DINA) in continuous flow**
(2023-03-05)Nitroxyethylnitramines (NENAs) and dinitroxydiethylnitramine (DINA) are useful energetic plasticizer components in propellants and explosives. However, their synthesis at large scale can be delicate because it involves two ... -
Matching radar signals and fingerprints with MPC
(2024-10-07)Vessels can be recognised by their navigation radar due to the characteristics of the emitted radar signal. This is particularly useful if one wants to build situational awareness without revealing one's own presence. Most ... -
Optimising collection geometry for long-range synthetic aperture sonar interferometry
(2024-06-21)Interferometric synthetic aperture sonar (SAS) is a technique to image and map theseabed in very high resolution. For large area coverage rate systems with hundreds ofmetres swath width, the achievable performance varies ... -
Estimating sensitivity with the Bruceton method: Setting the record straight
(2024-07-05)Accurate estimates of sensitivities of energetic materials are crucial for ensuring safe production, transport, usage and destruction of explosives. When estimating sensitivities, researchers most commonly follow the NATO ... -
