Journal ArticleDOI
Modal expansion of one‐way operators in laterally varying media
TL;DR: In this paper, the authors explore the possibility of applying this concept to the construction of one-way wavefield operators for depth migration, and obtain one way wavefield operator that are unconditionally stable and significantly increase the lateral resolution of the result.

Harmonic wavelet-based data filtering for enhanced machine defect identification
Ruqiang Yan,Robert X. Gao +1 more
TL;DR: In this paper, a generalized harmonic wavelet transform (GHWT) is used to construct a series of sub-frequency band wavelet coefficients for rotary machine defect detection. But the method is limited to rotary machines.
Journal ArticleDOI
Fast rotational matching.
Julio A. Kovacs,Willy Wriggers +1 more
TL;DR: A computationally efficient method is presented - 'fast rotational matching' or FRM - that significantly accelerates the search of the three rotational degrees of freedom (DOF) in biomolecular matching problems.

The spatial structure of edge fluctuations in the Wendelstein 7-AS stellarator
TL;DR: In this paper, the Wendelstein 7-AS stellarator was used to measure ion saturation current Isat and floating potential Φfl with high poloidal, radial and temporal resolution.

The effect of the Galactic spheroid on globular cluster evolution
TL;DR: In this paper, the combined effects of relaxation, tidal heating and binary heating on globular cluster evolution were studied, exploring the physical consequences of external effects and examining evolutionary trends in the Milky Way population.
