Cavalieri integrals differ from Riemann integrals in that non-rectangular integration strips are used. In this way we can use single ... Read more
Land-cover separability analysis of MODIS time-series data using a combined simple harmonic oscillator and a mean reverting stochastic process

Author: Grobler, TL ; Ackermann, ER ; Olivier, JC ; Van Zyl, AJ ; Kleynhans, W Date: Jun 2012 It is proposed that the time series extracted from moderate resolution imaging spectroradiometer satellite data be modeled as a simple harmonic oscillator with additive colored noise. The colored noise ismodeled with an Ornstein–Uhlenbeck ... Read more
