Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Low Rank Matrix Recovery for Seismic Data Analysis and Blind Superresolution
地震数据分析 盲超分辨率 低秩 矩阵恢复
2023/4/19
Low rank matrix recovery is about reconstructing a low rank matrix from incomplete measurements. It arises frequently in many research areas of science and engineering, for example, machine learning, ...
Improved techniques in data analysis and interpretation of potential fields:examples of application in volcanic and seismically active areas
gravimetry potential fields geomagnetism signal enhancement techniques
2015/9/25
Geopotential data may be interpreted by many different techniques, depending on the nature of the mathematical equations correlating specific unknown ground parameters to the measured data set. The in...
Data analysis of Permanent GPS networks in Italy and surrounding region:application of a distributed processing approach
Crustal deformations Satellite geodesy Data processing Plate boundaries, motion, and tectonics
2015/9/8
We describe the procedures used to combine into a uniform velocity solution the observations of more than 80 continuous GPS stations operating in the central Mediterranean in the 1998-2004 time interv...
