Abstract Integrated Seismic Program (ISP) is a graphical user interface designed to facilitate and provide user-friendly framework for performing diverse common advanced tasks in seismological research. ISP composed of five main modules earthquake location, time–frequency analysis signal processing, implementation array techniques estimate the slowness vector, seismic moment tensor inversion, r...

The failure mechanism of surrounding rock is an important issue in the field underground engineering. To quantitatively understand process and mass deep engineering, powerhouse Houziyan hydropower station was selected as a case study. study area determined by analysing spatiotemporal distribution microseismic (MS) events site investigations. After noise reduction, P-wave arrival time extraction...

Higher order tensor inversion is possible for even order. This is due to the fact that a tensor group endowed with the contracted product is isomorphic to the general linear group of degree n. With these isomorphic group structures, we derive a tensor SVD which we have shown to be equivalent to well-known canonical polyadic decomposition and multilinear SVD provided that some constraints are sa...

Dilute gas-particle flows can be described by a kinetic equation containing terms for spatial transport, gravity, fluid drag, and particle-particle collisions. However, the direct numerical solution of the kinetic equation is intractable for most applications due to the large number of independent variables. A useful alternative is to reformulate the problem in terms of the moments of the veloc...
