Web5 minutes ago · In the FTIR curve of the nanofiber dressings, there were wide strong peaks between 3200 and 3500 cm −1, which were caused by the vibration of O-H and N-H groups. The peak near 1598 cm −1 was formed by the vibration interaction of N-H, C-H, and C=O functional groups. WebSuppose each of the three time series have noise (this is why we would be interested in smoothing to begin with), then maybe a t = f ( t) + ϵ a, b t = g ( t) + ϵ b. Then the proportions x t = f ( t) + ϵ a g ( t) + ϵ b, which could be smoothed by taking x t ^ = f ( t) ^ g ( t) ^ time-series proportion smoothing signal-processing Share Cite
