  Developing a graphical tool for students to understand air resistance and free fall: when heavier objects do fall faster 

  Ferreira, Annalize; Seyffert, Albertus S.; Lemmer, Miriam (IOP, 2017)

  Abstract Many students find it difficult to apply certain physics concepts to their daily lives. This is especially true when they perceive a principle taught in physics class as being in conflict with their experience. ...
• Evaluation of design and planning parameter impact by energy efficient measures through appliance-based modelling 

  Alberts, Jaco A.; De Kock, Jan A. (IEEE, 2017)

  In a rapidly evolving industry as a result of consumer self-generation and a drive to become more energy efficient, it is necessary to understand whether traditional network planning methods are sufficient. Electrical ...
• Impact on power factor by small scale renewable energy generation 

  Alberts, Jaco A.; De Kock, Jan A. (IEEE, 2017)

  Domestic installations traditionally were believed to be resistive in nature and did not affect power factor much, if at all. With increasing affordability of air-conditioners, and replacement of electrical geysers with ...
• Evaluating the performance and emission reductions of a coal-derived low-smoke fuel in a conventional household stove 

  Sumbane, Lungile P.; Piketh, Stuart J.; Bunt, John R.; Neomagus, Hein W.J.P. (IEEE, 2017)

  A low-smoke fuel (LSF) produced via the devolatilisation of coal lumps is proposed as an option to combat the health-damaging effects of domestic coal combustion. This study investigates the effect of the LSF particle size ...
• Variability of domestic burning habits in the South African Highveld: a case study in the KwaDela Township (April 2017) 

  Nkosi, C. Ncobile; Piketh, J. Stuart; Burger, P. Roelof; Harrold, Annergan J. (IEEE, 2017)

  Air quality in the South African low-income residential areas is poor due to gaseous and particulate emissions from a range of sources including domestic burning. The absence of data on fuel use and variability in low-income ...
• The relationship between thermal comfort and indoor PM4 mass concentration within low-cost houses in Ikageng 

  Qhekwana, M.; Letsholo, T.; Burger, R.P.; Piketh, S.J. (IEEE, 2017)

  Solid fuels (wood, coal, and biomass) are used as alternative energy sources in South Africa, predominantly in low-income households. Space heating using wood is a common practice to obtain thermal comfort. Consequently, ...
• Rediscovery of Chonopeltis meridionalis Fryer, 1964 (Crustacea: Branchiura) from Labeo rosae Steindachner in the River Olifants, Mpumalanga, and the taxonomic status of C. victori Avenant-Oldewage, 1991 and C. koki Van As, 1992 

  Van As, Liesl L.; Smit, Nico J.; Van As, Jo G. (Springer, 2017)
