Efficiency analysis of an induction motor with field oriented control at a hot rolling mill
(Academic Journals, 2012)In this paper, the efficiency analysis of an induction motor with field-oriented control (FOC) at a hot rolling mill in South Africa is presented. It is shown that the energy consumption of an induction motor at a hot ... -
Efficiency and cost analysis of a designed in-line water heating system compared to a conventional water heating system in South Africa
(ERC (Energy Research Centre), 2012)In this paper, the authors compares the efficiency and cost of a designed in-line water heating system with a conventional water heating system (geyser) in South Africa. The paper provides an overview on water heating ... -
Efficiency behaviour of kernel-smoothed kernel distribution function estimators
(SASA, 2020)The asymptotic mean integrated squared error (AMISE) and the kernel efficiency (KE) of kernel distribution function estimators are well studied. In this note we define new nonparametric distribution function estimators by ... -
Efficiency measurements in IVR systems for oral users: Consequences of differences in educational levels
(South African Inst. for Computer Scientists and Information Technologists Conf. (SAICSIT), 2011)In this paper we present the development of an Interactive Voice Response (IVR) system that enables its users to obtain soccer results. The objective of the study is to evaluate the usability of the system through experiments ... -
The efficiency of South African mining companies to create shareholder and stakeholder value from enivronmental exploitation
(Babes-Bolyai University of Cluj Napoca, 2012)The aim of the study is to estimate the relative efficiency of nine South African mining companies in converting their environmental impact into shareholders’ gains and stakeholders’ gains. A data envelopment analysis model ... -
Efficient data selection for ASR
(Language Resources and Evaluation, 2015)Automatic speech recognition (ASR) technology has matured over the past few decades and has made significant impacts in a variety of fields, from assistive technologies to commercial products. However, ASR system development ... -
Efficient harvesting of Internet audio for resource-scarce ASR
(Interspeech 2011, 2011)Spoken recordings that have been transcribed for human reading (e.g. as captions for audiovisual material, or to provide alternative modes of access to recordings) are widely available in many languages. Such recordings ... -
Efficient market hypothesis in South Africa: evidence from linear and nonlinear unit root tests
(University of Primorska, 2015)This study investigates the weak form efficient market hypothesis (emh) for five generalized stock indices in the Johannesburg Stock Exchange (jse) using weekly data collected from31st January 2000 to 16thDecember 2014. In ... -
Efficient packet erasure decoding by transforming the systematic generator matrix of an RS code
(IEEE, 2008)We consider the erasures-only decoding of Reed-Solomon codes. One class of erasure decoders of algebraic codes can be viewed as a transformation of the systematic generator matrix, as first noticed by Berlekamp. We extend ... -
Efficient removal of Pb(II) and Cd(II) from industrial mine water by a hierarchical MoS2/SH-MWCNT nanocomposite
(ACS, 2019)In this study, we investigate the adsorption capability of molybdenum sulfide (MoS2)/thiol-functionalized multiwalled carbon nanotube (SH-MWCNT) nanocomposite for rapid and efficient removal of heavy metals [Pb(II) and ... -
Efficient waste reduction algorithms based on alternative underestimates for the modified Wang method
(Operations Research Society of South Africa, 2014)This paper is concerned with wastage reduction in constrained two-dimensional guillotine- cut cutting stock problems, often called trim loss problems. A number of researchers report in the literature on algorithmic ... -
Efflux as a mechanism of antimicrobial drug resistance in clinical relevant microorganisms: the role of efflux inhibitors
(Taylor & Francis, 2017)Introduction: Microbial resistance against antibiotics is a serious threat to the effective treatment of infectious diseases. Several mechanisms exist through which microorganisms can develop resistance against antimicrobial ... -
Efflux pumps genes of clinical origin are related to those from fluconazole-resistant Candida albicans isolates from environmental water
(IWA Publishing, 2018)Efflux pumps coded for by CDR1, CDR2, FLU1 and MDR1 genes could be responsible for the observed resistant phenotypes in azole-resistant Candida albicans from environmental water. This was demonstrated for clinical isolates. ... -
EFNEP's impact on exemplary educators' quality of life
(Elsevier, 2016)Objective: To determine how the Expanded Food and Nutrition Education Program (EFNEP) affects the quality of life (QoL) of its exemplary paraprofessional educators. Methods: Qualitative telephone interviews with EFNEP ... -
Egg banks in dryland wetlands provide information on the diversity and vulnerability of branchiopod communities along a longitudinal aridity gradient
(2022)Continued degradation of temporary wet-lands and rapidly declining freshwater biodiversity call for identification of vulnerable species as targets for conservation and management efforts. Branchiopod crustaceans are ... -
Ego boundaries and self-esteem: two elusive facets of the psyche of performing musicians
(Sage, 2016)This article presents a heuristic inquiry into ego boundary development and functioning in aspiring musicians. In their role as communicators in society, challenging and stretching existing boundaries form an integral ... -
Eietydse geskiedenis: 'n interdissiplinêre benadering
(University of the Free State, 2016)Contemporary history is essentially a multidisciplinary approach to explain the present or recent world. The historian, with utilisation of the time dimension and his capacity to see the dynamics of change through time ... -
Eigenvalue perturbation theory of symplectic, orthogonal, and unitary matrices under generic structured rank one perturbations
(Springer Verlag, 2014)We study the perturbation theory of structured matrices under structured rank one perturbations, with emphasis on matrices that are unitary, orthogonal, or symplectic with respect to an indefinite inner product. The rank ...
