Whаt is the relаtiоnship between stress, cоrtisоl, аnd BDNF?
Imаgine а scenаriо where Bоeing designed a pilоt monitoring system that deploys in response to a failing MCAS system. If an MCAS system is engaged and the pilot is detected to be stressed, MCAS will automatically disengage. In this system, consider a brain mobile interface application where the pilot wears a Neurosky headset that senses brain signals (EEG) at 400 Hz. Each brain data point is a 32-bit floating point number. The brain signal is collected by a central controller in the plane and sent to a server, where complex machine learning algorithms are employed to determine the stress level of the pilot. Additionally, the aircraft is equipped with sensors, such as the AoA, pitch monitoring, and other relevant sensors. The data rate from the AoA is 5 kbps, and the data rate from the other relevant sensors is 300 kbps. Using the data from these sensors, the MCAS disable system attempts to predict MCAS failures. If the system detects that the pilot is stressed and an MCAS failure is predicted, the auto-disable facility should disable MCAS. The auto-disable feature only has 5 seconds to make a decision after collecting 5 seconds worth of data. There are two options for performing all of the related computation: (a) use a GPU server at the control center, or (b) use a fog server that is onboard the aircraft. The GPU server upload speed is 1 Mbps, whereas the fog server upload speed is 5 Mbps. However, the computation speed of the GPU server is 1500 kbps (in other words, it can finish the computation on 1500 kb of data in 1 second), whereas the fog server has a computational speed of 200 kbps. What is the computation time for the GPU server in seconds?
