The purpose of this study is to introduce a multistage irregular shortest-path method (ISPM)
for tracking multiple seismic arrivals including any combinations of transmissions, reflections …

The solutions of traveltime inversion problems are often not unique because of the poor
match between the raypath distribution and the tomographic grid. However, by adapting the …

We present the concept, some of the approaches used, and the capabilities of the technique
referred to as GPS tomography. It is used for retrieval of the 3-dimensional distribution of the …

Passive seismic velocity tomography is a promising tool for use in evaluating rockburst risk
during underground coal mining, however, the traditional model gridding method will lead to …

针对计算截面为任意形状的非均匀密度二度体的重力问题, 提出了二维情况下的非规则重力建模
方法, 即利用二维Delaunay 剖分方法, 将其截面分割为若干三角形, 将该二度体分解成为若干 …

在井间地震初至走时层析成像中, 随着相邻地质体速度差的增大, 使得射线分布不均匀,
以及网格剖分不合适, 导致层析成像结果不理想. 物理和数值模型的井间走时层析成像表明 …

以二维大地电磁(Magneto-telluric, MT) 为例研究了自适应网格细化正则化反演方法.
在反演的初期使用粗网格, 通过减少反演单元数的方式降低反问题的不适定性; …

By late 2008 one of the most important pieces of the 'Museo delle Antichità Egizie'of Turin,
the sculpture of the Pharaoh with god Amun, was planned to be one of the masterpieces of a …

We present the results obtained by processing high‐resolution seismic data acquired along
the spring line located in the Friuli‐Venezia Giulia plain (NE of Italy), in order to characterize …

We present a novel adaptive model parametrization strategy for the 3-D electrical resistivity
tomography problem and demonstrate its capabilities with a series of numerical examples …
