A dynamic analysis model of the unbalanced vibration response a single-rotor system is established to study corresponding mechanism excitation force and caused by deviation rotor mass centroid in this paper, finally achieve combined suppression. First, installation multi-stage rotors during was studied, transfer rotating coordinate obtain vectors at all levels based on traditional stacking asse...

Common-midpoint (CMP) stacking technique plays an important role in enhancing the signal-to-noise ratio (SNR) in seismic data processing and imaging. Weighted stacking is often used to improve the performance of conventional equalweight stacking in further attenuating random noise and handling the amplitude variations in real seismic data. In this study, we propose to use a hybrid framework of ...

Visual secret sharing by using generalized random grids is a novel approach for generating nonexpansible shares by artfully utilizing various random variables. Stacking the shares together, secret image can be revealed. This paper proposes a 2 out of 3 visual multiple secret sharing method using generalized random grids. Three secret images (A, B, C) are used for generating three non-expansible...

H-κ stacking is a routinemethod for determining crustal thickness (H) and Vp/Vs (κ) using P-to-S (Ps) receiver functions. In this paper we show that S-to-P (Sp) receiver functions may also be used to determine crustal parameters. Sp provides independent information, complementary to Ps. We develop a method called H-V (crustal thickness-velocity) stacking where Ps and Sp receiver functions are s...

stability of the ;-; stacking interactions in the substituted-coronene||cyclooctatetraene complexes wasstudied using the computational quantum chemistry methods (where || denotes ;–; stackinginteraction, and substituted-coronene is coronene which substituted with four similar x groups; x =oh, sh, h, f, cn, and no). there are meaningful correlations between changes of geometricalparameters and t...
