  • Cavalieri integration 
    Ackermann, Etienne Rudolph; Grobler, Trienko Lups; Kleynhans, Waldo; Olivier, Jan Corne; Salmon, Brian Paxton; Van Zyl, A.J. (Taylor & Francis, 2012-04)
    We use Cavalieri’s principle to develop a novel integration technique which we call Cavalieri integration. Cavalieri integrals differ from Riemann integrals in that non-rectangular integration strips are used. In this ...
  • Land cover separability analysis of MODIS time series data using a combined simple harmonic oscillator and a mean reverting stochastic process 
    Grobler, Trienko Lups; Ackermann, Etienne Rudolph; Olivier, Jan Corne; Van Zyl, A.J. (Gusti); Kleynhans, Waldo (Institute of Electrical and Electronics Engineers, 2012-06)
    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 is modeled with ...
