Comparative study of Holt-Winters triple exponential smoothing and seasonal Arima: forecasting short term seasonal car sales in South Africa
(Virtus interpress, 2016)In this paper, both Seasonal ARIMA and Holt-Winters models are developed to predict the monthly car sales in South Africa using data for the period of January 1994 to December 2013. The purpose of this study is to choose ... -
Comparative study of morphology, morphometrics, reproductive fitness on carrot discs and pathogenicity on musa genotypes of Radopholus Similis Philippine populations
(ISSAAS, 2019)Comparative studies were conducted on three Radopholus similis populations collected in Quezon, Laguna and Davao, Philippines from 2008 to 2010. For the first time, morphological and morphometrical characteristics of the ... -
Comparative study of steam vs hot water as primary heat transfer medium for a laboratory scale two-tank heated system
(IEEE, 2019)The need exists for a benchmark multi-domain practical system that could emulate typical process faults for the purposes of condition monitoring. A proposition was made to develop a heated two-tank system, due to its ... -
A comparative study of the chemical composition of lucerne (Medicago sativa L.) and spinach beet (Beta vulgaris var. cicla L.)
(Elsevier, 2017)The chemical composition of three lucerne (Medicago sativa L.) cultivars (‘SA Standard’, ‘WL711’ and ‘WL525’) were compared to spinach beet (Beta vulgaris var. cicla L.), a familiar leafy vegetable (as control), in order ... -
Comparative study of the dissociative ionization of 1,1,1-trichloroethane using nanosecond and femtosecond laser pulses
(MDPI, 2010)Changes in the laser induced molecular dissociation of 1,1,1-trichloroethane (TCE) were studied using a range of intensities and standard laser wavelengths with nanosecond and femtosecond pulse durations. TCE contains ... -
A comparative study of the flora and soils of Great Duck and Little Duck Islands, Maine, USA
(New England Botanical Club, 2016)Strong environmental gradients and varied land-use practices have generated a mosaic of habitats harboring distinct plant communities on islands on the coast of Maine. Botanical studies of Maine's islands, however, are ... -
A comparative study of the processing scheme of chitosan and Nafion 117 in membrane electrode assembly
(Taylor & Francis, 2013)The authors considered two fabrication techniques in the fabrication of the membrane electrode assembly. It was observed that catalytic deposition through electro-spraying was not successful for chitosan and Nafion 117 ... -
A comparative study on fault detection and correction techniques on active magnetic bearing systems
(IEEE-Institute of Electrical and Electronics Engineers, 2007)In this paper, the authors distinguish between three real-time fault detection, correction and identification schemes for vibration forces on the rotor of a rotational active magnetic bearing (AMB) system. Historical fault ... -
A comparative study on the regulation of labour brokers in South Africa and Namibia in light of recent legislative developments
(Juta Law Publishing, 2015)In an attempt to remedy the lack of proper regulation of labour brokers, the South African government has amended the Labour Relations Act 66 of 1995, especially s 198. The amendments have now reached a point where they ... -
Comparative time-series analysis of MeV electron data by Ulysses and Pioneer 10/11 in the Jovian magnetosphere
(Copernicus Publications, 2013)The dynamics of the Jovian magnetosphere is dominated by the planet’s fast rotation with a period of 10 h.Within the magnetosphere, this periodicity can in particular be seen in the temporal variation of the spectral index ... -
Comparing algorithms to disaggregate complex soil polygons in contrasting environments
(Elsevier, 2019)In South Africa, the only soil resource available with full spatial coverage is the national resource inventory. Disaggregating this polygon-based inventory, is thus a logical step to create more detailed soil maps covering ... -
Comparing antibody responses in chickens against Plasmodium falciparum lactate dehydrogenase and glyceraldehyde-3-phosphate dehydrogenase with Freund’s and Pheroid® adjuvants
(Taylor & Francis, 2015)Pheroid® technology was assessed as an alternative to Freund’s adjuvant to raise antibodies in experimental animals. Chickens were immunized with two recombinantly expressed Plasmodium falciparum proteins, lactate dehydrogenase ... -
Comparing beverage consumption, physical activity and anthropometry among young adult urban- and rural-dwelling African women
(Medpharm, 2020)Beverage consumption, physical activity, body mass index and waist circumference were compared in age-matched (aged 18– 30 years) groups of young South African women from urban (n = 78) and rural (n = 94) settings. Obesity ... -
