Study of a hybrid solid oxide fuel cell: Energetic analysis and sankey diagram
In this paper a hybrid solid oxide fuel cell (SOFC) system is analyzed. This system applies a combined cycle utilizing gas turbine associated to a SOFC for rational decentralized energy production. Initially the relative ...
Failure probability metric by machine learning for online risk assessment in distribution networks
The risk assessment approach is useful for monitoring and supervisory control because it provides distribution operator with the capability to quantify the tradeoff between reliability and economic performance. The risk ...
Analysis of source separation algorithms in industrial acoustic environments
(Institute of Electrical and Electronics Engineers Inc., 2015)
This paper shows the results from the computation cost evaluation of three blind source separation algorithms. The algorithms tested were: FastICA, Adaptive Algorithm Based on Natural Gradient, and Adaptive EASI Based on ...
Georeferenced road extraction and formulation of hypotheses for new road segments
The acquisition and update of Geographic Information System (GIS) data are typically carried out using aerial or satellite imagery. Since new roads are usually linked to georeferenced pre-existing road network, the extraction ...
