Energy management by means of PLC for a solar powered ultra-capacitor streetlight system
(IRET (Institute of Research in Engineering and Technology), 2013)This paper presents the design of an energy management programmable logic controller (PLC) control program for a solar powered ultra-capacitor and battery powered streetlight system. A PLC is used to control the flow ... -
Energy management by means of SMD model analysis for AMB systems with eccentricity
(IRET (Institute of Research in Engineering and Technology), 2013)This paper provides the spring-mass-damper (SMD) model analysis of a radial active magnetic bearing (AMB) system that displays eccentricity. Energy management of AMB systems can be done by means of a detailed SMD model ... -
Energy management system for a residential grid-tied micro-grid
(IEEE, 2015)With the national power grid under tremendous pressure, there are enormous pressure exerted on residential electricity consumers to cut-back on electricity consumption to ensure a reliable supply. This has led to ... -
Energy monitoring and verification control interface for split unit air conditioners
(SPC, 2018)The aim of this paper is to present a new energy monitoring and verification control interface for the Eskom demand market participation (DMP) program that can be implemented on a commercial scale on all the split unit ... -
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 ... -
Energy savings in concrete production
(Crown Publications, 2014)T he rapid growth of the cement and concrete industry has created the need for concrete products such as concrete pipes, culverts, manholes, slabs, piles, etc. Since the role of electric machines in the concrete industry ... -
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 ... -
An energy-based approach to condition monitoring of industrial processes
(Elsevier, 2015)Condition monitoring has traditionally been deployed for the monitoring of a single component, such as a rotating electrical machine. The application of condition monitoring to an entire process plant has not yet received ... -
Energy-based fault detection for an autothermal reformer
(Elsevier, 2016)Condition monitoring has traditionally been deployed for the monitoring of a single component, such as a rotating machine. The application of condition monitoring techniques to entire petrochemical process plants, however, ... -
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 ... -
Energy-based visualisation of an axial-flow compressor system for the purposes of fault detection and diagnosis
(Elsevier, 2016)As the complexity of industrial systems increases, the necessity also increases for more reliable, robust and accurate Fault Detection and Diagnosis (FDD) techniques. This article proposes a methodology for the design of ... -
Engineering management and business intelligence: the importance of plant design base
(SAIIE, 2016)Most popular business improvement models center their framework and approaches around business process improvement – thus on people, process and technology aspects of the business. They tend to drive business process ... -
Engineering principles and medical discoveries

Enhancement of bio-methane production by lignocellulose substrates
(ETA-Florence Renewable Energies, 2015)In this study, water hyacinth, sweet sorghum bagasse and amaranth stems were used in a pig manure matrix to produce biogas with a high methane content. The anaerobic digestion was monitored over a period of 40 days, after ... -
Enthalpy-entropy graph approach for the classification of faults in the main power system of a closed Brayton cycle HTGR
(Elsevier, 2009)An enthalpy–entropy (h–s) graph approach for the classification of faults in a new generation type high temperature gas-cooled reactor (HTGR) is presented. The study is performed on a 165 MW model of the main power system ... -
Environmental assessment and nano-mineralogical characterization of coal, overburden and sediment from Indian coal mining acid drainage
(Elsevier, 2017)The deterioration of environmental conditions is the major contributory factor to poor health and quality of life that hinders sustainable development in any region. Coal mining is one of the major industries that contribute ... -
Environmental impact of an industrial compressed air system for solar power in South Africa
