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 ...
A self-sensing active magnetic bearing based on a direct current measurement approach
(MDPI, 2013)
Active magnetic bearings (AMBs) have become a key technology in various industrial applications. Self-sensing AMBs provide an integrated sensorless solution for position estimation, consolidating the sensing and actuating ...
Block RAM-based architecture for real-time reconfiguration using Xilinx® FPGAs
(South African Institute of Computer Scientists and Information Technologists, 2015)
Despite the advantages dynamic reconfiguration adds to a system, it only improves system performance if the execution time exceeds the configuration time. As a result, dynamic reconfiguration is only capable of improving ...
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 ...
An energy graph-based approach to fault diagnosis of a transcritical CO2 heat pump
(MDPI, 2020)
The objective of this paper is to describe an energy-based approach to visualize, identify, and monitor faults that may occur in a water-to-water transcritical CO 2 heat pump system. A representation using energy attributes ...
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 ...
Improving functional density of time-critical applications using hardware-based dynamic reconfiguration and bitstream specialisation
(South African Institute of Computer Scientists and Information Technologists, 2019)
The dynamic reconfiguration of an FPGA has many advantages, but the overhead from the process reduces the functional density of applications. Functional density is an indication of the composite benefits a reconfigured ...
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 ...
