Mueller Matrix Parameters for Radio Telescopes and their Observational Determination [PDF]
, 2001 Modern digital crosscorrelators permit the simultaneous measurement of all four Stokes parameters. However, the results must be calibrated to correct for the polarization transfer function of the receiving system. The transfer function for any device can

On the noise-resolution duality, Heisenberg uncertainty and Shannon's information [PDF]
, 2015 Several variations of the Heisenberg uncertainty inequality are derived on the basis of "noise-resolution duality" recently proposed by the authors. The same approach leads to a related inequality that provides an upper limit for the information capacity

Galactic rotation curves in modified gravity with non-minimal coupling between matter and geometry [PDF]
, 2010 We investigate the possibility that the behavior of the rotational velocities of test particles gravitating around galaxies can be explained in the framework of modified gravity models with non-minimal matter-geometry coupling. Generally, the dynamics of

Long-term analysis of clear nights using satellite data considering astronomical sites in western China [PDF]
Research in Astronomy and Astrophysics, 2020 Abstract A large ground-based optical/infrared telescope is being planned for a world-class astronomical site in China. The cloud-free night percentage is the primary meteorological consideration for evaluating candidate sites. The data from GMS and NOAA satellites and the MODIS instrument were utilized in this research, covering the ...

Astronomical observation tasks short-term scheduling using PDDS algorithm [PDF]
Astronomy and Computing, 2016 A concept of the ground-based optical astronomical observations efficiency is considered in this paper. We believe that a telescope efficiency can be increased by properly allocating observation tasks with respect to the current environment state and probability to obtain the data with required properties under the current conditions.
