OMG.. time is running out!

On May 7, there is a exam. And on the same day, I give a presentation at PolyU.

I prepare nothing yet for the exam, and my deflection routing is still "under construction."

And I have spent two days on studying Hurst exponent estimation on self-similar signal using wavelet transformation. Two days!!! which 28% of time from today to the day of exam.....

OMG..... stress stress stress...
