Earth as an Exoplanet: A Two-dimensional Alien Map

Iterated Monodromy for a Two-Dimensional Map

We compute the iterated monodromy group for a postcritically finite endomorphism F of P. The postcritical set is the union of six lines, and the wreath recursion for the group closely reflects the dynamics of F on these lines.

Correction to "A Two-Dimensional Doppler Radiometer for Earth Observation"

Compared to synthetic aperture radars (SARs), the angular resolution of microwave radiometers is quite poor. Traditionally, it has been limited by the physical size of the antenna. However, the angular resolution can be improved by means of aperture synthesis interferometric techniques. A narrow beam is synthesized during the image formation processing of the cross-correlations measured at zero...

creation of two-dimensional greenhouse environment map using stereo vision

in this research for detection and separation cultivation platforms and flowerpots from each other, localization the corner of platforms and position of the flowerpots to form of two-dimensional point and creation two-dimensional map of greenhouse, used three-dimensional coordinates of environment components. results obtained from this research, showed that the proposed algorithm can detect 100...

Telescope search for the transit of the Earth - mass exoplanet

Results from exoplanet surveys indicate that small planets (super-Earth size and below) are abundant in our Galaxy. However, little is known about their interiors and atmospheres. There is therefore a need to find small planets transiting bright stars, which would enable a detailed characterization of this population of objects.We present the results of a search for the transit of the Earth-mas...
