A Complex Equivalent Source Method for Scattering Effect of Aircraft Noise [PDF]
20th AIAA/CEAS Aeroacoustics Conference, 2014 An equivalent source method using equivalent monopoles in complex space is developed for calculating scattering effects for aircraft noise applications. The new method overcomes deficiencies in traditional equivalent real space source methods in treating

The Source Equivalence Acceleration Method [PDF]
Annals of Nuclear Energy, 2015 Abstract Fine-group whole-core reactor analysis remains one of the long sought goals of the reactor physics community. Such a detailed analysis is typically too computationally expensive to be realized on anything except the largest of supercomputers.

Acoustic Source Characterization of Marine Propulsors
Journal of Marine Science and Engineering, 2022 Marine propulsors represent one of the most important contributors among anthropogenic sounds radiated into water. Blade based propulsors, e.g., propellers, generate tones at the blade passing frequency and its harmonics, especially in cavitating ...

A Fast Iterative Shrinkage/Thresholding Algorithm via Laplace Norm for Sound Source Identification
IEEE Access, 2020 As a powerful tool, near-field acoustical holography (NAH) recognizes the sound source effectively. The traditional equivalent source method (ESM) calculated by the Tikhonov regularization method could be available in the low-frequency band.

Compatibility of high-altitude aeromagnetic and satellite-altitude magnetic anomalies over Canada [PDF]
, 2002 Results from equivalent-source distributions derived jointly from high-altitude (average 4 km) aeromagnetic and Magsat-derived (average 400 km) magnetic anomalies over Canada indicate that long-wavelength components (500–2500 km) in these fields are ...

The equivalent fundamental-mode source [PDF]
, 1996 In 1960, Hansen analyzed the problem of assembling fissionable material in the presence of a weak neutron source. Using point kinetics, he defined the weak source condition and analyzed the consequences of delayed initiation during ramp reactivity ...
