    CREAK descriptor evaluation for visual odometry 

    Smulders, Dehan; Uren, Kenneth; Van Schoor, George; Van Daalen, Corné; Engelbrecht, Japie (IEEE, 2019)
    Each year, latest state of the art technologies and algorithms arise that claim and prove to-shine their predecessors. One such algorithm is the Colour-based Retina Key-point (CREAK) descriptor, which is based on the FAST ...

    Delevitation modelling of an active magnetic bearing supported rotor 

    Janse van Rensburg, Jan J.; Van Schoor, George; Van Vuuren, Pieter A. (s.nCurran Associates, 2010)
    For active magnetic bearings (AMBs) to be used with confidence in industrial applications, the safe failure of the AMB system should be guaranteed. The exact behaviour of the rotor on the backup bearings (BBs) is relatively ...

    The characterization of the severity of rotor delevitation events: a parametric study 

    Janse van Rensburg, Jan J.; Van Schoor, George; Van Vuuren, Pieter A. (s.n, 2012)
    Active magnetic bearing (AMB) failure and the ensuing rotor behavior is a very important aspect of AMB safety. A model for this rotor behavior was developed and was used to characterize the severity of rotor delevitation ...

    Cathodic protection system design framework 

    Diedericks, Dewald E.; Van Schoor, George; Ranft, Eugén O. (IEEE, 2019)
    The aim of this article is to establish a cathodic protection (CP) system design framework for the petrochemical industry in South Africa. The CP system design framework is destined to be used as a guideline when designing ...

    Computational cost of an exergy-based fault detection scheme implemented in a commercial process simulator 

    Marais, Henri; Van Schoor, George; Uren, Kenneth R. (Elsevier, 2019)
    Energy-based fault detection and isolation (FDI) schemes show promise in terms of applicability to petrochemical industries and the broader process industries. Model-based FDI schemes offer pronounced advantages over more ...

    Statistical modelling of an ammonium nitrate fluidised bed granulator for inference measurement 

    Kok, Rudolph L.; Van der Merwe, Abraham F.; Van Schoor, George; Uren, Kenny R. (Elsevier, 2019)
    Fluidised bed granulation is a widely used wet granulation technique. The operation of a fluidised bed granulator (FBG) as well as the quality of the product is strongly influenced by multiple process variables and ...

    An energy-attributed graph approach for the purposes of FDI in a heated two-tank system 

    Uren, Kenneth R.; Van Schoor, George; Auret, Lidia (Elsevier, 2019)
    The focus of this paper is the development of attributed graph representations of industrial processes. In this case energy attributes are used since it serves a data reduction purpose and allows for the consideration of ...

    Series-parallel approach to on-line observer based neural control of a helicopter system 

    Hager, Louw vS.; Uren, Kenneth R.; Van Schoor, George (Elsevier, 2014)
    This paper is concerned with the control of an under-actuated, uncertain, delayed non-linear system through the implementation of arti cial neural networks(ANNs). The aim is the development of a series-parallel training ...

    Interdependent multi-objective sizing and control optimisation of a renewable energy hydrogen system 

    Human, Gerhardus; Van Schoor, George; Uren, Kenneth R. (Elsevier, 2014)
    This paper presents a sizing and control optimisation architecture for the design and evaluation of a small-scale stand-alone hybrid PV-wind-battery system for the production of hydrogen (H2) using proton exchange membrane ...

    Flight controller and low-cost test environment for a simulated helicopter 

    Terblanche, Martin C.; Uren, Kenneth R.; Van Schoor, George (IFAC, 2014)
    In this paper, optimal linear control techniques are utilised to control a radio-controlled helicopter (30 size) in the AeroSIMRC simulation environment. A grey-box time-domain system identification method is used to ...
