It can be seen from the figure that changes in porosity significantly alter the elastic modulus of the crack pore medium, which leads to changes in travel time and reflection coefficients with ...

Open source began as a rebellious idea to transform software development. Two decades later, it has firmly become the default ...

The phase and the group velocity of light propagating in conventional optical media cannot exceed the speed of light in ...

Abstract: We formulate and implement a spectral element method to simulate elastic wave propagation in an arbitrary anisotropic background with discrete anisotropic fractures. The approach uses a ...

Scientists from the University College London (UCL), the National Oceanography Centre (NOC), and the École Normale Supérieure ...

Short Wave New discoveries, everyday mysteries, and the science behind the headlines — in just under 15 minutes. It's science for everyone, using a lot of creativity and a little humor.

It is hard to determine the direction of seismic wave propagation under the condition of full space of mines, leading to difficulty in accurate fault detection. This paper compares and analyzes the ...
