Archives of Neurology And Psychiatry, 1919 Samuel Johnson (1759), in his "Rasselas, Prince of Abyssinia," sets forth very graphically the principles of flying. He says: He that can swim needs not despair to fly; to swim is to fly in a grosser fluid, and to fly is to swim in a subtler. We have only to proportion our power of resistance to the different density of matter through which we are to ...

Adapting Sentence Transformers for the Aviation Domain [PDF]
arXiv, 2023 Learning effective sentence representations is crucial for many Natural Language Processing (NLP) tasks, including semantic search, semantic textual similarity (STS), and clustering. While multiple transformer models have been developed for sentence embedding learning, these models may not perform optimally when dealing with specialized domains like ...

On Perception and Reality in Wireless Air Traffic Communications Security [PDF]
, 2016 More than a dozen wireless technologies are used by air traffic communication systems during different flight phases. From a conceptual perspective, all of them are insecure as security was never part of their design. Recent contributions from academic and hacking communities have exploited this inherent vulnerability to demonstrate attacks on some of ...

Advanced Engineering Materials, EarlyView.This article investigates optimal processing conditions for the laser‐based powder bed fusion of WE43. To limit the interaction with remaining oxygen, a 3 vol% hydrogen admixture to the inert gas is investigated. Furthermore, heat treatments are investigated in the range of 250–350 °C for 48 h.
