  • A generalized Freud weight 
    Clarkson, Peter A.; Jordaan, Kerstin Heidrun; Kelil, Abey (Wiley, 2016-04)
    We discuss the relationship between the recurrence coefficients of orthogonal polynomials with respect to a generalized Freud weight w(x; t ) = |x|2λ+1 exp(−x4 + tx2), x ∈ R, with parameters λ > −1 and t ∈ R, and classical ...
  • Generalized Geometry and Hopf Twists 
    Dlamini, Siphesihle Hector (University of Pretoria, 2016)
    The Leigh-Strassler theories are marginal deformations of the N = 4 SYM theory preserving N = 1 Supersymmetry. As such they admit a Hopf algebra structure which is a quantum group deformation of the SU(3) structure of the ...
  • Generalized linear mixed model and generalized estimating equation for binary longitudinal data 
    Sepato, Sandra Moepeng (University of Pretoria, 2014)
    The most common analysis used for binary data is generalised linear model (GLM) with either a binomial or bernoulli distribution using either a logit, probit, complementary log-log or other type of link functions. However, ...
  • A generalized model to estimate field size for solar-only parabolic trough plant 
    Channiwala, S.A.; Ekbote, A. (3rd Southern African Solar Energy Conference, South Africa, 11-13 May, 2015., 2015)
    Paper presented to the 3rd Southern African Solar Energy Conference, South Africa, 11-13 May, 2015.
  • Generalized multivariate beta distribution : control charting when the measurements are from an exponential distribution 
    Adamski, Karien; Human, Schalk William; Bekker, Andriette, 1958- (Springer, 2012)
    In Statistical Process Control (SPC) there exists a need to model the runlength distribution of a Q-chart that monitors the process mean when measurements are from an exponential distribution with an unknown parameter. ...
  • Generalized network transport and Euler-Hille formula 
    Banasiak, Jacek; Puchalska, Aleksandra (American Institute of Mathematical Sciences, 2018-07)
    In this article we consider asymptotic properties of network flow models with fast transport along the edges and explore their connection with an operator version of the Euler formula for the exponential function. This ...
  • A generalized solid state kinetic expression for reaction interface-controlled reactivity 
    Badenhorst, Heinrich; Rand, Brian; Focke, Walter Wilhelm (Elsevier, 2013-06)
    The ICTAC-recommended approach was used to characterize the gasification of high-purity, highly crystalline, large natural graphite flakes in oxygen. The average activation energy was found to be 157.7 ± 4.2 kJ mol−1. ...
  • Generalized solutions of systems of nonlinear partial differential equations 
    Van der Walt, Jan Harm (University of Pretoria, 2009-06-02)
    In this thesis, we establish a general and type independent theory for the existence and regularity of generalized solutions of large classes of systems of nonlinear partial differential equations (PDEs). In this regard, ...
  • Generalized statistics and the formation of a quark-gluon plasma 
    Teweldeberhan, Amanuel Matewos (University of Pretoria, 2007-05-17)
    Please read the abstract in the section 00front of this document
  • A Generalized theoretical deterministic particle swarm model 
    Cleghorn, Christopher Wesley (University of Pretoria, 2013)
    Particle swarm optimization (PSO) is a well known population-based search algorithm, originally developed by Kennedy and Eberhart in 1995. The PSO has been utilized in a variety of application domains, providing a wealth ...
  • A generalized theoretical deterministic particle swarm model 
    Cleghorn, Christopher Wesley; Engelbrecht, Andries P. (Springer, 2014-03)
    A number of theoretical studies of particle swarm optimization (PSO) have been done to gain a better understanding of the dynamics of the algorithm and the behavior of the particles under different conditions. These ...
  • Generally recognised accounting practice : a critical evaluation of the impact of grap 23 on administrative tax legislation and recommendations 
    De Vos, Gerhard Johannes (University of Pretoria, 2009)
    The application of accrual accounting principles is a challenge for public sectors internationally and increases the level of transparency and accountability of management. Taxation authorities are governed by legislation ...
  • A generally weighted moving average chart for time between events 
    Chakraborty, Niladri; Human, Schalk William; Balakrishnan, N. (Taylor and Francis, 2017-05)
    Shewhart-type attribute charts are known to be inefficient for small changes in monitoring nonconformities. An alternative way is to use a time-weighted chart to monitor the time between events (TBE). We propose a one-sided ...
  • A generally weighted moving average exceedance chart 
    Chakraborty, Niladri; Human, Schalk William; Balakrishnan, Narayanaswamy (Taylor and Francis, 2018-03)
    Distribution-free control charts gained momentum in recent years as they are more efficient in detecting a shift when there is a lack of information regarding the underlying process distribution. However, a distribution-free ...
  • A generally weighted moving average signed-rank control chart 
    Chakraborty, Niladri; Chakraborti, Subhabrata; Human, Schalk William; Balakrishnan, N. (Wiley, 2016-12)
    The idea of process monitoring emerged so as to preserve and improve the quality of a manufacturing process. In this regard, control charts are widely accepted tools in the manufacturing sector for monitoring the quality ...
  • Generating a theory from predicting the success level of assurance representatives 
    Lane, Liezel (University of Pretoria, 2001)
    The aim of this research was to generate a theory to predict the success levels of assurance sales representatives. A sample of 245 participants from a life insurance company in South Africa was selected to participate in ...
  • Generating an improved quality of informal housing in Mamelodi, South Africa 
    Peeters, Nele; Osman, Amira (IAHS World Congress on Housing, 2005-09-26)
    Human settlements play a central role in determining the progress of a country; housing is an indicator of wealth or poverty. In developing countries, satisfactory housing is often the exception to the rule. The people ...
  • Generating Armstrong ABoxes for ALC TBoxes 
    Harmse, Henriette; Britz, Katarina; Gerber, Aurona Jacoba (Springer, 2018-11)
    A challenge in ontology engineering is the mismatch in expertise between the ontology engineer and domain expert, which often leads to important constraints not being specified. Domain experts often only focus on specifying ...
  • Generating hope in pastoral care through relationships 
    Steyn, Tobias Hertzog van Reenen; Masango, Maake J.S. (OpenJournals Publishing, 2012-05-07)
    This article concerned itself with the notion of Christian hope, in the midst of suffering, where this hope will find its energy from within a relationship with God and his people. Hope in God finds its substance from ...
  • Generating ideas and managing suggestion systems in organisations : some empirical evidence 
    Du Plessis, Andries J.; Marx, Andrew E.; Wilson, Gregory (Common Ground, 2008)
    Methods used to generate ideas and suggestions differ. It is generally accepted that employees from all levels in the organisation are involved in the design, but the respondents have different opinions. Suggestion systems ...
