High-Precision Waveform Stacking Location Method for Microseismic Events Based on S-Transform
SensorsThe waveform stacking location method achieves microseismic source localization by computing characteristic functions (CFs) and stacking multi-channel data, without phase picking. It has been widely applied in geotechnical engineering.

On a uniqueness theorem for characteristic functions
Nonlinear Analysis, 2017 Suppose that f is the characteristic function of a probability measure on the real line R. We deal with the following open problem posed by N.G. Ushakov: Is it true that f is never determined by its imaginary part Im f?

On certain generating functions in positive characteristic
, 2016 We present new methods for the study of a class of generating functions introduced by the second author which carry some formal similarities with the Hurwitz zeta function.

Exponential functions in prime characteristic
, 2005 In this note we determine all power series $F(X)\in 1+X\F_p[[X]]$ such that $(F(X+Y))^{-1} F(X)F(Y)$ has only terms of total degree a multiple of $p$. Up to a scalar factor, they are all the series of the form $F(X)=E_p(cX)\cdot G(X^p)$ for some $c\in ...

Multi-operator colligations and multivariate characteristic functions
, 2010 In the spectral theory of non-self-adjoint operators there is a well-known operation of product of operator colligations. Many similar operations appear in the theory of infinite-dimensional groups as multiplications of double cosets.

Characteristic functions and averages [PDF]
, 2013 Let $\Omega$ be a set and $\Omega_1,\ldots,\Omega_{m-1}$ subsets of $\Omega$, being $m$ an integer greater than one. For a given function $f=(f_1,\ldots f_m):\Omega\rightarrow\mathbb{R}^m$, we prove the existence of a unique function $\alpha=(\alpha_1 ...

Axiomatic Attribution for Multilinear Functions [PDF]
, 2011 We study the attribution problem, that is, the problem of attributing a change in the value of a characteristic function to its independent variables. We make three contributions.
