Pseudo-acoustic inversion method and its application
2010 Seventh International Conference on Fuzzy Systems and Knowledge Discovery, 2010In the study area, the oil reservoir is mainly of structural-lithologic type. Their lithology varies dramatically in both lateral and vertical directions. Additionally, oil-water relation of the reservoir is complicated and the seismic data are full of multiplicity, which makes it very difficult to predict the reservoirs. There is such an insignificant

Multi-Parameter Pseudo Acoustic Full Waveform Inversion Method in Elastic World
82nd EAGE Annual Conference & Exhibition, 2021Summary In land seismic exploration, low-velocity zone causes the ray path of reflected wave propagating to the detector perpendicularly. Therefore, single-component data is regarded as P-wave data. In this paper, we first derive a new pseudo acoustic wave equation (PAE) in elastic world based on acoustic approximation.

Aeroacoustic Source Identification Using a Weighted Pseudo Inverse Method
16th AIAA/CEAS Aeroacoustics Conference, 2010This paper presents a new algorithm to perform general acoustic source identiflcation. In this special case, the so called Weighted Pseudo Inverse technique is applied to the identiflcation of acoustic sources on propellers. One of the advantages of this new method is that the problem does not need to be well conditioned to perform the source ...

Pseudo-Inverse Matrix Method - A Direct Method for Non-Isothermal Kinetic Analysis
Journal of Thermal Analysis and Calorimetry, 1998A new method is reported for the evaluation of non-isothermal kinetic data for various forms of the conversion function. The algorithm is based on a pseudo-inverse matrix method. A description of the algorithm and some calculation examples are presented.

Spectral Reconstruction and Accuracy Appraisal Based on Pseudo Inverse Method
2012 Symposium on Photonics and Optoelectronics, 2012Explained based on the pseudo-inverse method spectral reflectance restructuring principle, and has confirmed the entire restructuring process using the experiment and Matlab, and used the root-mean- square error, the color difference has carried on the appraisal for the spectrum restructuring aceuracy and the color chromaticity match aceuracy.

Stability of the pseudo-inverse method for reconfigurable control systems
International Journal of Control, 1991Abstract One of the key reconfigurable control methods, the pseudo-inverse method (PIM), is analysed and new insight is obtained which provides the theoretical basis for this practical approach. The main shortcoming of this method, the lack of stability guarantees, is pointed out and a new approach is proposed in which recent results on the stability ...

Robust Estimation and the Pseudo‐Inverse Method for Geophysical Inversion
Chinese Journal of Geophysics, 2000AbstractRobust estimation is introduced into geophysical inversion for data with large errors which are named outliers in order to obtain a good solution, which is called Geophysical Robust Estimation. But if a linear equation system is ill‐conditioned, the inversion solution is still not reliable.
