Krigsspill i operasjonsplanlegging: Hva kan datasimuleringer bidra med?
(2022-09-19)Krigsspill er en sentral aktivitet i operasjonsplanlegging for både å utvikle alternative handlemåter og utvikle plan basert på valgt handlemåte. Å gjennomføre krigsspill i et operativt miljø har stramme føringer i forhold ... -
A Computational Protocol for Vibrational Circular Dichroism Spectra of Cyclic Oligopeptides
(2022-08-05)Cyclic peptides are a promising class of compounds for next-generation antibiotics as they may provide new ways of limiting antibiotic resistance development. Although their cyclic structure will introduce some rigidity, ... -
Using the Pauli Scattering Mechanisms for Analysis of Polarimetric SAR Images from RADARSAT Constellation and TanDEM-X Missions
(2022-07-13)This article describes techniques for extraction of information in polarimetric images from RADARSAT constellation mission (RCM) and TanDEM-X (TDX) and TerraSAR-X (TSX) satellites. Using the boundary conditions of Maxwell's ... -
Challenges of Labelling Unknown Seabed Munition Dumpsites from Acoustic and Optical Surveys: A Case Study at Skagerrak
(2022-05-31)The disposal of unexploded ordnance (UXOs) at sea is a global problem. The mapping and remediation of historic UXOs can be assisted by autonomous underwater vehicles (AUVs) carrying sensor payloads such as synthetic aperture ... -
Modeling FMCW Radar for Subsurface Analysis
(2022-04-05)Determining subsurface properties through ground penetrating radar sounding can be challenging, especially in planetary exploration, where little is known about the terrain and additional observations are limited. Analysis ... -
Analysis of samples of high explosives extracted from explosive remnants of war
(2022-10-10)Millions of tonnes of dumped ammunition and explosive remnants of war remain in nature both on land and at sea. It is well known that the ordnance could represent a definite explosive risk if disturbed, and that some of ... -
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 ... -
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 ... -
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 ... -
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, ... -
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 ... -
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 ... -
Unimolecular Decomposition Reactions of Picric Acid and its Methylated Derivatives — A DFT Study
(2022-04-26)To handle energetic materials safely, it is important to have knowledge about their sensitivity. Density functional theory (DFT) has proven a valuable tool in the study of energetic materials, and in the current work, DFT ... -
Behavioral responses to predatory sounds predict sensitivity of cetaceans to anthropogenic noise within a soundscape of fear
(2022-03-21)As human activities impact virtually every animal habitat on the planet, identifying species at-risk from disturbance is a priority. Cetaceans are an example taxon where responsiveness to anthropogenic noise can be severe ... -
