k-Wave is an open source MATLAB toolbox designed for the time-domain simulation of propagating acoustic waves in 1D, 2D, or 3D [1]. The toolbox has a wide range of functionality, but at its heart is ...
a) MAIN_rectangle for a simulation on a 2D rectangle b) MAIN_pdetool for a simulation on a 2D mesh coming from pde_tool draw (you can also build your own mesh - see later *) c) MAIN_convergence_h for ...

New warp-drive claim questions need for exotic matter, experts debate
A series of recent theoretical papers argue that some subluminal “warp-drive” spacetime designs could avoid the traditional requirement for “exotic” negative-energy matter, or at least reduce/shift ...
In this lesson, we introduce the one dimensional wave equation and explore how it appears in electrodynamics. This video explains the basic concepts, physical meaning, and mathematical form of the ...
The wave equation is a very important formula that is often used to help us describe waves in more detail. It should be noted that some particular waves have their own specific speeds. The speed of ...
Alex's identity is revealed in the Paradise season 2 finale along with how Xavier is connected to saving the world.
When waves meet a gap or an edge in a barrier, they continue through the gap or past the edge of the barrier. This may seem obvious but what happens on the far side of the gap or barrier is not so ...
Abstract: Imaging using S-wave seismic data based on elastic media holds the potential to address certain critical issues that conventional P-wave imaging cannot resolve, thereby offering new ...
Abstract: In marine seismic data processing, velocity errors in deep-sea water can lead to distortions in seabed positioning, which in turn cause deformations in deeper geological strata. The existing ...
Introduction Climate-sensitive mortality in rapidly urbanising tropical Africa is poorly characterised, and how pandemics ...
In this paper we study one-dimensional Fisher-Kolmogorov equation with density dependent non-linear diffusion. We choose the diffusion as a function of cell density such that it is high in highly cell ...
