Class II 6.7 GHz methanol maser association with young massive cores revealed by ALMA
(IOP, 2017)We explored the implication of the association (or lack of it) of 6.7 GHz class II methanol (CH3OH) masers with massive dense cores (MDCs) detected (within a sample of ATLASGAL selected infrared quiet massive clumps) at ... -
A class of goodness-of-fit tests based on a new characterization of the exponential distribution
(Taylor & Francis, 2008)A new characterisation of the exponential distribution in the class of new better than used in expectation (NBUE) life distributions is presented. Utilising this characterisation, a new class of goodness-of-fit tests for ... -
A class of goodness-of-fit tests for circular distributions based on trigonometric moments
(IDESCAT, 2019)We propose a class of goodness–of–fit test procedures for arbitrary parametric families of circular distributions with unknown parameters. The tests make use of the specific form of the characteristic function of the ... -
Class ranking of secondary schools in the North West province of South Africa
(ORSSA, 2016)The education system in South Africa finds itself in a dismal position. Existing research reports and general news bulletins suggest that schools in South Africa suffer from a general lack of efficiency measures and therefore ... -
Classes of sequentially limited operators
(Cambridge Univ Press, 2016)The purpose of this paper is to present a brief discussion of both the normed space of operator p-summable sequences in a Banach space and the normed space of sequentially p-limited operators. The focus is on proving that ... -
Classical and fractional analysis of the effects of silicosis in a mining community
(Elsevier, 2020)A mathematical model for the transmission dynamics of silicosis in a mining environment is designed and its qualitative analysis is given. The model takes into account the severity of silica dust exposure in a mining ... -
Classical model of Prandtl's boundary layer theory for radial viscous flow: application of (G'/G)- expansion method
(Eudoxus Press, 2017)In this paper, the exact closed-form solutions of the Prandtl's boundary layer equation for radial ow models with uniform or vanishing mainstream velocity are derived by using the (G'/G)-expansion method. Many new exact ... -
Classification and description of the vegetation in the Spitskop area in the proposed Highveld National Park, North West Province, South Africa
(AOSIS, 2012)The objective of the proposed Highveld National Park (HNP) is to conserve a considerable area of the poorly conserved Rocky Highveld Grassland and Dry Sandy Highveld Grassveld of the western Grassland Biome in South Africa. ... -
Classification and taxonomy of vegetable macergens
(Frontiers Media, 2015)Macergens are bacteria capable of releasing pectic enzymes (pectolytic bacteria). These enzymatic actions result in the separation of plant tissues leading to total plant destruction. This can be attributed to soft rot ... -
Classification of the Eastern Scarp Forests
(Springer, 2018)This chapter brings the first comprehensive classification of the Eastern Scarp Forest. These are very fragmented and relictual forests, structurally complex, rich in tropical elements as well as species of conservation ... -
Classifying aerosol type using in situ surface spectral aerosol optical properties
(EGU, 2017)Knowledge of aerosol size and composition is important for determining radiative forcing effects of aerosols, identifying aerosol sources and improving aerosol satellite retrieval algorithms. The ability to extrapolate ... -
Classifying Africans with the Metabolic Syndrome
(Thieme, 2009)This study was aimed to compare prevalences of the metabolic syndrome in Africans using five definitions as proposed by the World Health Organization (WHO), the European Group for the Study of Insulin Resistance (EGIR), ... -
Classifying bent radio galaxies from a mixture of point-like/extended images with machine learning
(IEEE, 2016)The hypothesis that bent radio sources are supposed to be found in rich, massive galaxy clusters and the avalibility of huge amount of data from radio surveys have fueled our motivation to use Machine Learning (ML) to ... -
Classifying bilinear differential equations by linear superposition principle
(World Scientific Publishing, 2016)In this paper, we investigate the linear superposition principle of exponential traveling waves to construct a sub-class of N-wave solutions of Hirota bilinear equations. A necessary and sufficient condition for Hirota ... -
Classifying objects in space according to South African property law
(Nelson Mandela Metropolitan University, 2016)Traditionally, objects were classified according to their relation to man or according to their own nature. The classical division according to their relation to man relates to the question of whether something is susceptible ... -
Classifying recognised speech with deep neural networks
(Southern African Conference for Artificial Intelligence Research, 2020)We investigate whether word embeddings using deep neural networks can assist in the analysis of text produced by a speechrecognition system. In particular, we develop algorithms to identify which words are incorrectly ... -
Classroom assessment of reading comprehension: how are preservice Foundation Phase teachers being prepared?
(University of Stellenbosch, 2011)A number of assessment studies in recent years have shown that the educational achievement of learners in South African schools is unacceptably poor. The Department of Education’s systemic evaluations, conducted in Grade ... -
Clayey materials in river basin enhancing microbial contamination of river water
(Elsevier, 2014)Mineral constituents of clay materials may promote interaction, adsorption and attachment of microorganisms, often resulting in biofilms’ formation. In this study investigation is made to determine how littoral clayey ... -
Clergies and self-care during the COVID-19 pandemic : a challenge to pastoral care
(AOSIS, 2022)On the 15th of March 2020, the current president of the Republic of South Africa, Mr Cyril Ramaphosa, declared a National State of Disaster as a response to the coronavirus disease 2019 (COVID-19). A range of regulations ... -
Client perceptions of interaction with community pharmacists in the Nelson Mandela Metropole
(Taylor & Francis, 2017)Communication plays an important role in health care professions, such as pharmacy, which is an information-driven profession in which community pharmacists are embedded. They are responsible for ensuring patient-centred ...
