The program seeks new kinds of cognitive radio techniques that enable wireless communications that autonomously find open radio frequencies and choose the most efficient RF waveform to avoid interference, achieve necessary range, and send data quickly.
Intelligent RF transceivers
Cognitive radio describes an RF transceiver that intelligently can detect which communication channels are in use, which ones are not, and instantly move into vacant channels. The same principles could apply to radar, electronic warfare (EW) and other RF and microwave applications.
Weather forecasting is a powerful tool. During hurricane season, for instance, meteorologists create computer simulations to forecast how these destructive storms form and where they might travel, which helps prevent damage to coastal communities.
When you’re trying to forecast space weather, rather than storms on Earth, creating these simulations gets a little more complex.
To simulate space weather, you would need to fit the Sun, the planets, and the vast empty space between them in a virtual environment, also known as a simulation box, where all the calculations would take place.
YouTube is currently facing a global outage, with users reporting playback errors on both the website and mobile apps.
When trying to watch videos, users see messages like “Playback error” or “Something went wrong,” while some say the site is slow or not loading at all.
The outage began within the last 30 minutes.
