Heat recovery of dedusting systems in electric arc furnaces: concept of a bottoming cogeneration plant and techno-economic analysis
(2018-01-01)
Steelworks require large amount of energy in reduction, fusion and refining processes. A mini-mill is a steelwork that produces steel by melting scrap metal, pig iron and metallic elements in electric arc furnaces. Depending ...
Electric load forecasting using a fuzzy ART&ARTMAP neural network
(Elsevier B.V., 2005-01-01)
This work presents a neural network based on the ART architecture ( adaptive resonance theory), named fuzzy ART& ARTMAP neural network, applied to the electric load-forecasting problem. The neural networks based on the ...
Operation planning of electrical distribution systems using a mixed integer linear model
(2013-10-01)
This article presents a mixed integer linear programming model for the problem of operation planning of an electrical distribution system. The model defines the most appropriate adjustment of a set of control variables to ...
Optimal reconfiguration of electrical distribution systems using mathematical programming
(2014-01-01)
This paper presents a novel mixed integer nonlinear programming (MINLP) model for the reconfiguration problem of electrical distribution systems (EDS), aiming to reduce the active power losses of the system. Two linearization ...
Automatic system for thermal damage detection in manufacturing process with Internet monitoring
(2006-07-17)
This work involved the development of a smart system dedicated to surface burning detection in the grinding process through constant monitoring of the process by acoustic emission and electrical power signals. A program ...
Job satisfaction among control room operators of electrical systems
(IOS PRESSAMSTERDAM, 2012)
Shift workers from control centers of electrical systems are a group that has received little attention in Brazil. This study aimed to compare workers' job satisfaction at five control centers of a Brazilian company ...
Allocation of the cost of transmission losses in a multimarket framework
(2006-10-25)
The paper addresses the issue of apportioning of the cost of transmission losses to generators and demands in a multimarket framework. Line flows are unbundled using equivalent bilateral exchanges on a DC-network model and ...
Ecomorphology of the digestive tract of the brazilian electric ray Narcine brasiliensis (Olfers, 1831) (Torpediniformes: Narcinidae)
(2017-07-01)
Elasmobranchii shows particular characteristics that make them susceptible to the impacts caused by fishing pressure, especially bottom trawling, which mostly affect rays, as they have demersal habits. Based on food ...
Estimating the generation of waste electrical and electronic equipment in organizations: The case of a Brazilian federal agency
(2021-12-01)
The generation of waste electrical and electronic equipment (WEEE) has become a globally serious problem. Its adequate management has great importance for governments and organizations alike. Despite the available literature ...
Study of thresholds to burning in surface grinding process
(2005-04-01)
This work aims at finding out the threshold to burning in surface grinding process. Acoustic emission and electric power signals are acquired from an analog-digital converter and processed through algorithms in order to ...
