Noise-resistant device-independent certification of Bell state measurements [PDF]
Physical Review Letters, 2018 Device-independent certification refers to the characterization of an apparatus without reference to the internal description of other devices. It is a trustworthy certification method, free of assumption on the underlying Hilbert space dimension and on ...

Toward Noise Certification during Design: Airframe Noise Simulations for Full-Scale, Complete Aircraft. [PDF]
CEAS Aeronaut J, 2019 An overview of a recent, NASA-sponsored effort to substantially advance simulation-based airframe noise prediction is presented. An accurate characterization of this component of aircraft noise requires a high-fidelity representation of the finer geometrical details associated with the landing gear and wing high-lift devices, such as slats and flaps ...
