On conventional track at a speed of 30km/h, the sleeper deflection was 1.15mm while the beam deflection was 0.57mm on Tubular track under the same conditions. TMT has been installed at a number of ...

Blue Origin and NASA are teaming up on a new mission to protect Earth from asteroids, building on NASA's DART success.

GXBeam is a pure Julia implementation of Geometrically Exact Beam Theory, originally based on the open source code GEBT and its associated papers[1] [2], though it has since been augmented with a ...

Abstract: Accurate characterization of surfaces using cantilever-based optical beam deflection (OBD) systems is crucial for obtaining the sample’s “true” topography and its corresponding material ...

NASA’s DART mission, the first-ever planetary defense test in space, sent a spacecraft to crash into an asteroid in 2022. That mission was a success. It showed that, in a hypothetical scenario where a ...

Millions of asteroids orbit the Sun. Smaller fragments often brush the Earth’s atmosphere to light up the sky as meteors. Once every few centuries, a meteoroid has sufficient size to cause regional ...

We demonstrate a novel approach to X-ray ptychography, a phase-sensitive scanning microscopy method. By replacing the conventional sample scanning approach with a beam-scanning via reflective optics, ...

School of Mechanical Engineering, National Technical University of Athens, Athens, Greece. A Google Scholar search for the term “Timoshenko beam” currently yields approximately 127,000 results—an ...

If you want to build semiconductors at home, it seems like the best place to start might be to find a used scanning electron microscope on eBay. At least that’s how [Peter Bosch] kicked off his ...
