By adopting a polar coordinate system, rotation, and retraction steps, the manufacturing of these structures can be easy achieved." Many advanced 3D printing techniques, with fast printing speed ...

However, determining these polar coordinates relies on the COordinate Rotation DIgital Computer (CORDIC), a power-hungry circuit block. CORDIC generates multi-bit amplitude and phase signals that ...

Exactly when that will happen is being influenced by humans, according to a new study, as melting polar ice alters the Earth’s rotation and changes time itself. The hours and minutes that ...

and finally an encoder was added to the base of the plotter to more accurately correct positional errors in the rotating arm mechanism. With everything said and done, the polar coordinate plotter ...
