Slat noise source studies for farfield noise prediction

7th AIAA/CEAS Aeroacoustics Conference and Exhibit, 2001
Todays low-noise high-bypass-ratio engines have made airframe noise for large commercial aircraft in the approach configuration to be compatible to that of the engines. As a consequence, flow noise from landing gears and from high lift devices (HLD) on wings - and its control - will become ever more important.

Ultra low noise current sources

IEEE Instrumentation and Measurement Technology Conference Sensing, Processing, Networking. IMTC Proceedings, 1998
The current sources which are normally used in research laboratories are not suitable for low noise measurement systems because of the unacceptable level of low frequency noise which they introduce in the measurement chain. The most important source of low frequency noise in such instruments is the solid state device (usually a Zener diode) which is ...

Sources of noise in photoreceptor transduction

Journal of the Optical Society of America A, 1987
Photoreceptors are surprisingly noisy, and the properties of this noise are providing clues to the molecular mechanisms underlying phototransduction. Three distinct components of noise arise from excitation of the rhodopsin photopigment molecule: the first is activation by photons, and the second is thermal activation in darkness.

Aircraft magnetic noise sources

8th International Congress of the Brazilian Geophysical Society, 2003
Aeromagnetic aircraft and data acquisition systems generate magnetic interference which can effect the quality of the data collected. Many people believe that traditional aircraft compensation, which models the permanent, induced, and eddy-current sources, can remove all of this interference.
