Cavalieri integration

Author: Ackermann, ER ; Grobler, TL ; Kleynhans, W ; Olivier, JC ; Salmon, BP ; Van Zyl, AJ Date: Sep 2012 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 way we can use single ... Read more
Cavalieri Integration - CSIR Technical report

Author: Grobler, TL ; Ackermann, ER ; Van Zyl, AJ ; Olivier, JC Date: Oct 2011 The authors use Cavalieri's principle to develop a novel integration technique which they call Cavalieri integration. Cavalieri integrals differ from Riemann integrals in that non-rectangular integration strips are used. In this way they can ... 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
Systematic Luby Transform codes as incremental redundancy scheme

Author: Grobler, TL ; Ackermann, ER ; Olivier, JC ; Van Zyl, AJ Date: Sep 2011 Systematic Luby Transform (fountain) codes are investigated as a possible incremental redundancy scheme for EDGE. The convolutional incremental redundancy scheme currently used by EDGE is replaced by the fountain approach. The results of the ... Read more
Using Page’s cumulative sum test on MODIS time series to detect land-cover changes

Author: Grobler, TL ; Ackermann, ER ; Van Zyl, AJ ; Olivier, JC ; Kleynhans, Waldo ; Salmon, Brian P Date: 2012 Human settlement expansion is one of the most pervasive forms of land-cover change in South Africa. The use of Page’s cumulative sum (CUSUM) test is proposed as a method to detect new settlement developments in areas that were previously ... Read more
Wu’s algorithm and its possible application in cryptanalysis

Author: Grobler, TL ; Van Zyl, AJ ; Olivier, JC ; Kleynhans, W ; Salmon, BP ; Penzhorn, WT Date: Jan 2012 In this paper we reviewed Wu’s algorithm and introduced it as a cryptanalysis technique. This study reveals that when Wu’s algorithm is used for cryptanalysis it simplifies. This is true because Wu’s algorithm has to be applied to binary ... Read more
