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 ... -
Simulation supported CBRNE accident coordination training
(2024-10-24)The utilization of computer simulations and virtual environments offers a cost-effective solution for education, training, and exercises. These platforms provide training audiences exposure to scenarios that may be too ... -
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 ... -
Using drone swarms with manoeuvre units
(2024-10-17)We have examined the use of drone swarms in support of mechanized units at low tactical level. This has primarily been done through simulations. We have used the same interface for controlling the swarm in the simulator, ... -
Sikre beregninger fra kryptografi – hvordan samarbeide om hemmelige data uten å røpe hemmeligheter
(2024-10-23)Ved hjelp av moderne kryptografi kan vi utføre sikre beregninger, der ingen får innsyn i andre data enn de skal. Det gjør oss i stand til å redusere risikoen som følger av å dele data med andre organisasjoner eller ... -
Veien mot bærekraftige investeringsprosjekter i forsvarssektoren – en empirisk studie
(2024-10-15)Den nye langtidsplanen for forsvarssektoren legger opp til en historisk forsvarssatsing, med betydelige investeringer i både materiell og eiendom, bygg og anlegg (EBA). I henhold til langtidsplanen skal forsvarssektoren ... -
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 ... -
Temporal Answer Set Programming for gjenkjenning av kjente cyberangrepsmønstre
(2024-09-17)Dette notatet er skrevet for å dokumentere et sommerstudentprosjekt som omhandler bruk av ASP-solveren telingo [1] til å gjenkjenne kjente cyberangrepsmønstre. Med utgangspunkt i et eksperiment av Grov mfl. [3], har vi ... -
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 ... -
Bolstering the Bastion: The Changing Pattern of Russia's Military Exercises in the High North
(2024-09-18)Between 2015 and 2022, Russia conducted a number of naval and air exercises, including live-fire drills, in the international waters and airspace on NATO’s northern flank. Some of this activity took place in the Norwegian ... -
Assessing Radar Attenuation in RIMFAX Soundings at the Jezero Western Fan Front, Mars
(2024-07-02)Estimates of radar attenuation in the shallow Martian subsurface are retrieved from RIMFAX soundings along the Perseverance rover traverse. Specifically, analyzed data is from the Hawksbill Gap area during the rover's first ... -
Capture and Release of Minke Whales Offers New Research Opportunities, Including Measurements of Mysticete Hearing
(2024-09)Knowledge about species-specific hearing is vital to assessing how anthropogenic noise impacts marine mammals. Unfortunately, no empirical audiogram exists for any mysticete whale. We therefore developed a catch-and-release ... -
Riding the yellow wave: the online populist communication of Rassemblement National (RN) leaders in response to the Gilets Jaunes protests and the 2019 European elections
(2024-07-02)Radical-right populist parties will often try to exploit and ride a wave of popular discontent for their own electoral gain. This paper studies the online populist communication of the leaders of the Rassemblement National ... -
Failures in Ukrainian Arms Procurement 2014-2023 The Negative Effects of Limited Access Orders (LAOs) on National Security
(2024-07-15)This article discusses critical failures in Ukrainian defense production and procurement in the period 2014 to 2023. The main puzzle is why Ukraine did so little to satisfy the needs of the country’s armed forces in essential ... -
Glyceraldehyde metabolism in mouse brain and the entry of blood-borne glyceraldehyde into the brain
(2024-06-22)D-Glyceraldehyde, a reactive aldehyde metabolite of fructose and glucose, is neurotoxic in vitro by forming advanced glycation end products (AGEs) with neuronal proteins. In Alzheimer's disease brains, glyceraldehyde-containing ... -
Generalizing the Black and Scholes Equation Assuming Differentiable Noise
