Introduction to Spectral and Correlation Analysis: Basic Measurements and Methods,e fast Fourier transform (FFT) algorithm. In this context, leakage and time windowing are explained, after which we go into detail on how to compute the spectra for each type of signal. Two different methods are described: Welch’s method, based on averaging several shorter DFT blocks, and the periodSeizure 发表于 2025-3-27 09:06:30
Pollen Evidence for Human-Induced Landscape Change Reveals the History of Agricultural Development in Southeastern Chinainterland and mountainous areas in South China show evidence for the onset of profound anthropogenic influence on subtropical mountain forests around 1.0 cal ka BP. This environmental transformation coincides with the timing of large-scale immigrations of war refugees from the north during the Tang and Song Dynasties.Itinerant 发表于 2025-3-27 09:30:19
