Travel time is a variable that varies over both time and space. Hence, an ideal formulation should be able to capture its evolution over time and space. A mathematical representation capturing such variations was formulated from first principles, using the concept of conservation of vehicles. The ...
Then, the first-arrival traveltime and amplitude can be extracted from the phase and amplitude of monochromatic frequency-domain wavefield. In order to obtain the optimum combination of the frequency and damping factor, we propose a parameter analysis scheme for all possible combinations. The ...
We’ve been doing “life travel” for five years now. When the kids were young, it seemed like they would be that way forever and we could travel using the same formula in perpetuity. All of a sudden we have a high school kid in the house with a tween close behind. In this article...
LATTE: Los Alamos TravelTime package based on Eikonal equation We develop an open-source package for traveltime computation, tomography and source location in 2D/3D isotropic acoustic/elastic media. The work was supported by Los Alamos National Laboratory (LANL) Laboratory Directory Research and Devel...

A wave equation-based local traveltime inversion algorithm is proposed for seismic inversion Local domain cross correlation and energy weighted misfit are proposed to attenuate the cross-talk noise A multiwindow strategy is applied to further improve the inversion result Plain Language Summary The high...
Space travel calculator – relativistic rocket equation Now that you know whether interstellar travel is possible and how fast we can travel in space, it's time for some formulas. In this section, you can find the "classical" and relativistic rocket equations that are included in the relativisti...
