The use of multitaper estimates for spectral proper orthogonal decomposition (SPOD) is explored. Multitaper and multitaper-Welch estimators that use discrete prolate spheroidal sequences (DPSS) as orthogonal data windows are compared to the standard SPOD algorithm that exclusively relies on weighted ...
Unlocking massively parallel spectral proper orthogonal decompositions in the PySPOD package We propose a parallel (distributed) version of the spectral proper orthogonal decomposition (SPOD) technique. The parallel SPOD algorithm distributes the s... M Rogowski,BCY Yeung,OT Schmidt,... - 《Computer...
The proper orthogonal decomposition (POD) method for analysis of nonlinear panel flutter subjected to supersonic flow is presented. Optimal POD modes are extracted from a chaotic Galerkin mode responses. The aeroelastic equations of moti... X Dan,X Min,H Dai,... - 《Journal of Sound & Vibrat...
We use spectral proper orthogonal decomposition (SPOD) to extract and analyze coherent structures in the turbulent wake of a disk at Reynolds number $\Rey = 5 imes 10^{4}$ and Froude numbers $\Fro$ = $2, 10$. SPOD modes, which vary with modal index $(n)$ and frequency ($\Str$...
(73) has been obtained by solving the proper Dyson equation for G to the first-order approximation in the interaction Hamiltonian with an approximate self-energy Σ of the system, and making use of the Ansatz mentioned above. Equation (72) could be considered as a special form of scattering...
The eigenvectors of these latter matrices are engineered so as to favour the information transfer from the reading frame to the output layer, upon proper encoding. The associated eigenvalues represent the primary target of the novel learning scheme. In the following we will set up the method, ...
The signal decomposition (and reconstruction) techniques developed in this book have three salient characteristics: (1) Orthonormality. As we shall see, the block transforms will be square unitary matrices, i.e., the rows of the transformation matrix will be orthogonal to each other; the subband...
This resulted in eight libraries: four libraries with 4,046 compounds each for the COSMIC training dataset and four libraries with 3,291 compounds each for the independent dataset. Notably, the COSMIC training dataset is a proper subset of the CSI training dataset; if we simply refer to ‘trai...
Proper speech production requires auditory speech feedback control. Models of speech production associate this function with the right cerebral hemisphere while the left hemisphere is proposed to host speech motor programs. However, previous studies have investigated only spectral perturbations of the audito...
Proper stress, LLLI and combined application of these two can increase the secretions of ALP in osteoblasts compared to the control group. But the secretions of ALP decreased when combined application of stress and LLLI compared to using alone. LLLI can regulate the changing rhythm of ...
