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 ...
Understanding Influence Operations in Social Media: A Cyber Kill Chain Approach
(2020-11-14)
Discussions about recent state-run influence operations in social media often focus only on quantitative elements—the number of people interacting with fake news or how many tweets were sent by bots. This article suggests ...
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 LoRa Mesh Network Asset Tracking Prototype
(2020)
Long Range (LoRa) is a low powered wide area communications technology, which uses radio frequencies in the industrial, scientific and medical (ISM) band to transmit data over long distances. Due to these properties, i.e., ...
No Country for Old Men? Increasing the Retirement Age in the Norwegian Armed Forces
(2020-05-25)
Ageing workforces due to low fertility rates and higher life expectancies challenge modern industrialized economies. In order to secure economic welfare and to balance public budgets, governments worldwide implement reforms ...
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 ...
