In this work, we present a modified Time-Reversal Mirror (TRM) Method, called Source Time Reversal (STR), to find the spatial distribution of a seismic source induced by mining activity. This methodology is based on a known ...

We investigated the role of open innovation in the reverse innovation process. Reverse innovation is an innovation initially launched in a developing country and later introduced to an advanced country. Von Zedtwitz et al. ...

In this paper we study the phase portraits in the Poincaré disk of the reversible vector fields of type (2;0) having generic bifurcations around a symmetric singular point p. We also prove the nonexistence of any periodic ...
