If the ratio is around 1 then it's round. If it's more than 1 it's not as round. 댓글 수: 4 이전 댓글 2개 표시 Image Analyst 2023년 7월 7일 draw_multiple_polygons.m drawCircle_demo.m drawline_demo.m ...

To account for the angle-dependence of the concentration profile around each particle j, we have modified Eq. (1) by an angle-dependent function f(Θ) to $$c_i\left( t \right) = \tilde c\mathop {\sum }\limits_{i \ne j} \frac{\sigma }{{r_{ij}\left( t \right)}}e^{ -...

The COSIMA mass spectrometer on-board Rosetta was equipped with an optical microscope, Cosiscope, which identified several 10,000 cometary particles collected on targets exposed during the orbital phase around the nucleus of comet 67P Churyumov-Gerasimenko. The median value of reflectance factors ...
In another studypublished in the same series, a team led by Scheeres and McMahon tried to figure out if ejection events might even influence Bennu’s own orbit around the sun—the answer is probably not. The group did discover something else unusual: When particles ev...
This is what happens when a fragmented comet crosses the orbit of a planet like Jupiter, Saturn, etc. We used the dynamical system that is formed by two main bodies (the Sun and one of the planets of the Solar System) and we assumed that they are in circular orbits around their center...
Schematic of the experimental setup and the phoretic motion. (a) A passive Janus polystyrene (ps) bead with a thin gold (au) cap (thermophoretic mobilities\(\mu _{\mathrm{ps}}\),\(\mu _{\mathrm{au}}\)) is exposed to the temperature gradient around a laser-heated immobilized gold nan...
size-resolved mass distributions for PL, PA, and FT, there was a mode around 150–200 nm and the remaining mass was allocated with larger particle sizes up to the detection limit of 10 μm (Fig.1b). The particle concentrations measured by the four DiSCmini devices followed the same...
