Abstract: To solve the time-optimal problem of velocity planning, various optimization-based methods were proposed in the literature, but these existing methods typically have limitations on ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Abstract: Accurate seismic velocity inversion is crucial for oil and gas exploration. The popular fixed-scale regular-grid adjoint-state first-arrival (or first-arrival travel-time) slope tomography ...

A galaxy cluster 10 billion light-years away glows with energy: white marks galaxies, red shows a newly found radio mini-halo, and blue traces hot X-ray-emitting gas. (Chandra X-ray Center via ...

The streaming age has certainly brought a number of benefits for consumers and viewing audiences, not the least of which is the ability to stream top-tier content on demand, anytime, from the comfort ...

I have seen a slope function 'pyflwdir.dem.slope'. But it seems to me like slope of D8 flow direction. I need to calculate the slope of D-inf flow direction. I guess some changes in the code of ...

Auto race drivers view time from a variety of perspectives. Have you ever found yourself in a professional race, navigating through your days and sometimes feeling like you're going in circles? We all ...

Whether it's deciding when to meet a friend for coffee or setting up a meeting for work, scheduling is annoying. The inevitable back-and-forth—“I'm free Monday, does that work?” “No, I'm busy then, ...

Calculating slope on a graph is vital for understanding many different aspects of life – from engineering and business to nature and art. With simple techniques like using two points or the rise over ...
