• Ripple compensation for a class-D amplifier 

      Cox, Stephen M.; Mouton, H. du Toit (Society for Industrial and Applied Mathematics, 2015)
      ENGLISH ABSTRACT: This paper presents the first detailed mathematical analysis of the ripple compensation technique for reducing audio distortion in a class-D amplifier with negative feedback. The amplifier converts a ...
    • Rapid calculation of antenna noise temperature in offset Gregorian reflector systems 

      De Villiers, Dirk I. L.; Lehmensiek, Robert (Institute of Electrical and Electronics Engineers, 2015)
      Antenna noise temperature calculations of reflector systems is often a slow process and makes direct optimization of the sensitivity of these systems a difficult and time consuming task. This paper presents an improvement ...
    • Clustering acoustic segments using multi- stage agglomerative hierarchical clustering 

      Lerato, Lerato; Niesler, Thomas (Public Library of Science, 2015)
      Agglomerative hierarchical clustering becomes infeasible when applied to large datasets due to its O(N2) storage requirements. We present a multi-stage agglomerative hierarchical clustering (MAHC) approach aimed at large ...
    • Afrikaans and Dutch as closely-related languages : a comparison to West Germanic languages and Dutch dialects 

      Heeringa, Wilbert; De Wet, Febe; Van Huyssteen, Gerhard B. (University of Stellenbosch, Department of General Linguistics, 2015)
      Following Den Besten’s (2009) desiderata for historical linguistics of Afrikaans, this article aims to contribute some modern evidence to the debate regarding the founding dialects of Afrikaans. From an applied perspective ...
