CREAK descriptor evaluation for visual odometry
(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
(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
(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 ...
An energy perspective on modelling, supervision, and control of large-scale industrial systems: survey and framework
(IFAC, 2014)
Energy is a universal concept that can be used across physical domains to describe complex large-scale industrial systems. This brief survey and framework gives a perspective on energy as a unifying domain for system ...
Statistical modelling of an ammonium nitrate fluidised bed granulator for inference measurement
(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
(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 ...
Computational cost of an exergy-based fault detection scheme implemented in a commercial process simulator
(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 ...
Cathodic protection system design framework
(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 ...
Pseudo-magnetic centre identification of an active magnetic bearing for sensorless drive control start-up
(Elsevier, 2017)
A method of identifying runout of an active magnetic bearing at standstill and low speed is presented. The on-line current bias injection method found in literature is improved, but is still found to converge too slowly ...
Energy-based visualisation of a counter-flow heat exchanger for the purpose of fault identification
(Elsevier, 2016)
The need for fault detection and diagnosis (FDD) is becoming increasingly important for industrial processes as the complexity of processes increases. A state space model of a counter-flow heat exchanger is used study to ...
