A novel architecture to realize the conversion of rectangular to polar coordinates is presented in this paper. The proposed technique for phase calculation uses a logarithmic number system and does ...

When converting to Cartesian coordinates from indicial coordinates, care must be taken so that the resultant X-, Y-, and Z-axes in the Cartesian system define a right-handed coordinate system. IMPPY3D ...

It includes ellipsoid parameters and datums for different coordinate systems, and methods for converting between them and to Cartesian coordinates. erkir::Vector3d implements 3-d vector manipulation ...

Technological limitations for manufacturing large, round telescopes has experts considering unconventional shapes to improve ...

"We show that this design can, in principle, find half of all existing Earth-like planets orbiting sun-like stars within 30 light-years in less than three years." ...

The space-based telescope would be similar in size to the James Webb Space Telescope but with a 20-by-1-meter elongated ...

A new rectangular telescope design could finally spot Earth-like planets around nearby stars, bringing the search for alien ...

A bold new proposal from a team of astrophysicists, led by Heidi Newberg from Rensselaer Polytechnic Institute, suggests that ...

In this paper, we propose a novel task polar coordinate frame based on the spatial snapshot at a given time. The advantages of the proposed frame possess the following highlights.
