    • Automated mine compressed air control for sustainable savings 

      Jonker, Jeandré (North-West University (South Africa) , Potchefstroom Campus, 2016)
      Compressed air generation consists of approximately 19% of a mine’s total electricity consumption. It was found that manually operated compressed air networks are controlled inefficiently. The need exists to reduce the ...
    • Automated processing of untargeted 1H-NMR metabolomics data of urine from treated TB patients 

      Van der Westhuizen, Jessica (North-West University (South Africa), 2022)
      Metabolomics is becoming an increasingly popular field of study. An analytical platform commonly used for metabolomics studies is proton nuclear magnetic resonance (1H-NMR) spectroscopy. The main challenge of 1H-NMR is ...
    • An automated solution to facilitate sustainable DSM in the mining environment 

      Steyl, Jacob Petrus (North-West University, 2008)
      South Africa is experiencing a serious electricity supply problem. This problem is expected to persist until at least 2012. During the winter of 2006 load shedding and electricity supply-cuts started occurring in the Western ...
    • Automatic alignment of audiobooks in Afrikaans 

      Van Heerden, Carel J.; De Wet, Febe; Davel, Marelie H. (Pattern recognition association of South Africa (PRASA), 2012)
      This paper reports on the automatic alignment of audiobooks in Afrikaans. An existing Afrikaans pronunciation dictionary and corpus of Afrikaans speech data are used to generate baseline acoustic models. The baseline system ...
    • Automatic genre classification of English students' argumentative essays using support vector machines 

      Raaff, Sabrina (North-West University, 2007)
      Automatic text classification refers to the classification of texts according to topic. Similar to text classification is the automatic classification of texts based on stylistic aspect of texts, such as automatic genre ...
    • Automatic infarct planimetry by means of swarm-based clustering 

      Van Vuuren, Pieter A.; Van Vuuren, Derick (PRASA, 2014)
      Infarct planimetry is an important tool in cardiology research. At present this technique entails that infarct size is manually determined from scanned images of prepared heart sections. Existing attempts at automating ...
    • Automatic lemmatisation for Afrikaans 

      Groenewald, Hendrik Johannes (North-West University, 2006)
      A lemmatiser is an important component of various human language technology applicalions for any language. At present, a rule-based lemmatiser for Afrikaans already exists, but this lemmatiser produces disappointingly low ...
    • Automatic modulation classification system for OFDM signals 

      Rossouw, M. (North-West University (South Africa), 2020)
      Automatic modulation classification (AMC) is the process of automatically determining the modulation technique used in a received signal. An important part of identifying an unknown signal is to determine its modulation ...
    • Automatic Modulation Classification through clustering in the I/Q plane 

      Mouton, J.P. (North-West University (South Africa), 2020)
      Automatic Modulation Classification (AMC) refers to a process where the modulation scheme of a signal of interest is determined. It is not a requirement of an AMC system to recover the original data contained in the signal. ...
    • Automatic Recognition of Code-Switched Speech in Sepedi 

      Modipa, Thipe Isaaih (2016)
      Code switching (CS) is a natural phenomenon that is often observed in multilingual speakers. These speakers use words, phrases or sentences from foreign languages and embed them in sentences in the primary language. ...
