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 ...
High-energy bow tie multi-pass cells for nonlinear spectralbroadening applications
(2022-01-24)
Multi-pass cells (MPCs) have emerged as very attractive tools for spectral broadening and
post-compression applications. We discuss pulse energy limitations of standard MPCs considering
basic geometrical scaling principles ...
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 ...
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 ...
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 ...
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 ...
Numerical study of premixed gas explosion in a 1-m channel partly filled with 18650 cell-like cylinders with experiments
(2022-03-22)
Abused and defective Li-ion cells can cause a catastrophic failure of a Li-ion battery (LIB), leading to severe fires and explosions. In recent years, several numerical and experimental studies have been conducted on the ...
