A weakening transatlantic relationship? Redefining the EU-US security and defence cooperation
(2022-05-18)
The aim of this article is to discuss how a weakening transatlantic relationship influences European defence cooperation and integration. It also asks how these observed patterns of weakening EU–US relations can be explained ...
Security for Autonomous and Unmanned Devices: Cryptography and its Limits
(2022-02-07)
We survey existing literature on protecting resource constrained autonomous and unmanned devices. The goal is to secure data both during transmission and at rest, also when facing highly skilled and motivated adversaries. ...
Dispersion of SARS-CoV-2 in air surrounding COVID-19-infected individuals with mild symptoms
(2022-02-12)
Since the beginning of the pandemic, the transmission modes of SARS-CoV-2—particularly the role of aerosol transmission—have been much debated. Accumulating evidence suggests that SARS-CoV-2 can be transmitted by aerosols, ...
Abstracts from The Cold Weather Operations Conference 2021
(2022-03-11)
A common effort for both military and civil healthcare is to achieve knowledge-based health care in cold weather injuries and fatal accidents in harsh arctic environment. The Cold Weather Operations Conference in November ...
How extending the kinematic model affects path following in off-road terrain for differential drive UGVs
(2022-05-31)
Traversal in off-road conditions for Unmanned Ground Vehicles is highly relevant for defence applications, with an increasing amount of research being put into the field. A central part of the autonomous traversal is path ...
Military Muscle-Flexing as Interstate Communication: Russian NOTAM Warnings off the Coast of Norway, 2015–2021
(2022-06-14)
When, where, and why does Russia issue warnings about missile launches and other potentially dangerous military activities in international waters and airspace west and north of Norway? Drawing on information derived from ...
Segmentation of PMSE data using random forests
(2022-06-22)
EISCAT VHF radar data are used for observing, monitoring, and understanding Earth’s upper atmosphere. This paper presents an approach to segment Polar Mesospheric Summer Echoes (PMSE) from datasets obtained from EISCAT VHF ...
Population Based Routing in LEO Satellite Networks
(2022-06-26)
Packet switching in a Low Earth Orbit (LEO) satellite network may calculate the best traffic route through the less populated areas of the planet, in order to avoid relaying through the busiest satellites. A number of ideas ...
Cooperative Caching in Space Information Networks
(2022-05-22)
Members of a Low Earth Orbit (LEO) satellite group need to coordinate their activities in order to improve the quality and timeliness of the services provided to terrestrial clients. As a report from a work in progress, ...
Correlations between sound speed and density in seabed sediment cores collected in Norwegian waters
(2022-08-08)
In modelling of underwater sound propagation, knowledge about the seabed’s acoustic properties is essential, especially sound speed and density. These two properties are highly correlated, and standard empirical regressions ...
