PURPOSE: An SNR compensating method of a satellite camera with a non linear model is provided to determine exposure time and an accumulation frequency and compensate for an SNR of the satellite camera by the determined result.;CONSTITUTION: Noise characteristics of a satellite camera are analyzed(...
To investigate the cause of SNR 0509, astronomers Bradley Schaefer and Ashley Pagnotta of Louisiana State University studied archived Hubble data from the Advanced Camera for Surveys and the Wide Field Camera 3 to search for a surviving star that could have fed the doomed white dwarf. However, ...

This section is to measure the actual SNR10 with the classic methodology. SNR10 with CCM applied is very useful to validate a camera sensor system noise performance, the smaller of the tested result, the better of the camera system noise performance. Image capturing conditions Below table shows ...

Two-dimensional (2D) pixelated Optical-Wireless-Communication-Systems (OWCS), with Intensity-Modulation, Direct-Detection (IM/DD), commonly use computer-display (on transmit-side), and camera (on receive-side). One-dimensional (1D) IM/DD OWCS and channels, which use discrete optical components...
a rapid, largely unknown, ABA-independent osmotic-stress signalling pathway. Here, through a combination of a redundancy-circumventing genetic screen and biochemical analyses, we have identified functionally-redundant MAPKK-kinases (M3Ks) that are necessary for activation of SnRK2 kinases. These M3Ks...
