Noise has great influence on the signal analysis for centrifugal compressor. In order to eliminate the noise, the iterative singular value decomposition (ISVD) de-noising is applied in this paper. Firstly, the algorithm of this method is introduced. It is based on singular value decomposition about the trajectory matrix of attractor which is reconstructed according to time delay embedding theor...
In magnetic resonance electrical impedance tomography (MREIT) we inject currents through electrodes placed on the surface of a subject and try to reconstruct cross-sectional resistivity (or conductivity) images using internal magnetic flux density as well as boundary voltage measurements. In this paper we present a static resistivity image of a cubic saline phantom (50 x 50 x 50 mm3) containing...
Characterization of myocardial deformation in genetically manipulated mouse models with MR tagging provides new opportunities for elucidating the molecular mechanisms of cardiac function. However, tagging on murine hearts presents additional challenge because of the requirement for high tagging and imaging resolution. The high heart rate of mice renders EPI or segmented k-space sampling impract...
We generalize the multi step prediction cost function for an unbiased reconstruction of the dynamics for noisy time series recently proposed for the case of scalar time series (which requires a reconstruction in delay space) to the case of multivariate time series data. 1 Given a time series with irregular time dependence the reconstruction of the underlying deterministic dynamics ooers probabl...
