In the frequency tracking loop, the frequency difference between QVCO and QILO is extracted using the QILO's amplitude modulated (AM) envelope waveform. The AM frequency of the envelope signal bears ...

The excavation near Loop 88 has already dug up a giant find — the tooth of a Giant Ground Sloth. Update: Here's what else was found in the excavation “We know we’ve found Giant Ground Sloth ...

To address this problem, a laser SLAM method called PA-SLAM based on ground plane constraints and two-step accurate identification of loopback frames is proposed. In the point cloud preprocessing ...

The Square Kilometre Array (SKA) in the Karoo is one of the most sensitive scientific instruments on the planet –so sensitive that it could detect a cellphone signal on Pluto. This level of ...
