The 3S3 experiment data report - using operational naval sonars to study the effects of continuous active sonar, and source proximity, on sperm whales
(2021-03-18)
The 3S project is an international collaborative effort with the aim to investigate behavioral
reactions of cetaceans to naval sonar signals. The objectives of the third phase of the project
(3S3) were to investigate if ...
Performance of drag force models for shock-accelerated flow in dense particle suspensions
(2021-04)
Models for prediction of drag forces within a particle cloud following shock-acceleration are evaluated with the aid of results from particle-resolved simulations in order to quantify how much the disturbances introduced ...
Environmental Adaptation of Robot Morphology and Control Through Real-world Evolution
(2021-03-30)
Robots operating in the real world will experience a range of different environments and tasks. It is essential for the robot to have the ability to adapt to its surroundings to work efficiently in changing conditions. ...
Laminar burning velocity of gases vented from failed Li-ion batteries
(2021-06-10)
In the last decade, several fires and explosions caused by Li-ion batteries (LIBs) have been reported. This can be attributed to the thermal runaway and catastrophic failures of LIBs that release combustible gases, which ...
A global metagenomic map of urban microbiomes and antimicrobial resistance
(2021-06-24)
We present a global atlas of 4,728 metagenomic samples from mass-transit systems in 60 cities over 3 years, representing the first systematic, worldwide catalog of the urban microbial ecosystem. This atlas provides an ...
Quantification of aerosol dispersal from suspected aerosol-generating procedures
(2021-12-06)
Background Oxygen-delivering modalities like humidified high-flow nasal cannula (HFNC) and noninvasive positive-pressure ventilation (NIV) are suspected of generating aerosols that may contribute to transmission of disease ...
Økonomiske virkemidler for å oppnå strategiske mål – en oversikt
(2021-03-05)
Tradisjonelt har en stat benyttet militære maktmidler for å forsvare sin suverenitet, territorium og befolkning.
Det er nå økende fokus på hvordan også virkemidler innen det økonomiske domenet kan benyttes av en stat

Hvordan påvirkes alderspensjonen dersom alle tillegg og overtid blir pensjonsgivende?
(2021-08-09)
Militært personell må ofte jobbe til ukurante tidspunkt, på ukurante steder og tidvis med økt risiko for liv og
helse. Dette blir de kompensert for med ulike tillegg og overtid. De fleste tillegg og overtid er imidlertid ...
Hovedpunkter for en teknologisk transformasjon
(Forsvarets forskningsinstitutt (FFI), 2021-12-16)
Politiet, Politiets Sikkerhetstjeneste (PST) og Den høyere påtalemyndighet, forkortet politi- og
påtaletjenestene, må følge teknologiutviklingen tett. Dette er avgjørende for å kunne vurdere
teknologiske løsninger og ...
