Dual-tree complex wavelet transform applied to fault monitoring and identification in aeronautical structures
(2014-01-01)
This paper proposes the application of the dual-tree complex wavelet transform on fault monitoring and identification in aeronautical structures. For this purpose, a multiscale analysis from phase of the complex wavelet ...
A METHODOLOGY FOR THE DETECTION AND DIAGNOSTIC OF LOCALIZED FAULTS IN GEARS AND ROLLING BEARINGS SYSTEMS
(Universidad de Tarapacá., 2010)
A fault detection and diagnosis technique for multivariate processes using a PLS-decomposition of the measurement space
(Elsevier Science, 2013-10)
A newstatisticalmonitoring technique based on partial least squares (PLS) is proposed for fault detection and diagnosis inmultivariate processes that exhibit collinear measurements. A typical PLS regression (PLSR) modeling ...
Low cost monitoring system for safe production of hydrogen from bio-ethanol
(Elsevier, 2013-10-25)
In this paper a monitoring system is developed to guarantee safety operational conditions for the hydrogen production from bioethanol. The key idea is to detect the most critical faults with the minimum number of sensors. ...
Fault Detection in Power Distribution Systems Using Automated Integration of Computational Intelligence Tools
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011)
The main purpose of this paper is to present architecture of automated system that allows monitoring and tracking in real time (online) the possible occurrence of faults and electromagnetic transients observed in primary ...
A fault location method using Lamb waves and discrete wavelet transform
(Associação Brasileira de Engenharia e Ciências Mecânicas - ABCM, 2012)
On-line fault diagnostic system for proton exchange membrane fuel cells
(ELSEVIER SCIENCE BV, 2008)
In this paper, a supervisor system, able to diagnose different types of faults during the operation of a proton exchange membrane fuel cell is introduced. The diagnosis is developed by applying Bayesian networks, which ...
Fault Location in Distribution Systems Based on Smart Feeder Meters

Condition-based monitoring system for rolling element bearing using a generic multi-layer perceptron
(Sage Publications Ltd, 2015-12-01)
Rolling element bearings are critical mechanical components in rotating machinery and fault detection in the early stages of damage is important to prevent their malfunctioning and failure. Vibration monitoring is the most ...
New contributions to non-linear process monitoring through kernel partial least squares
(Elsevier Science, 2014-07)
The kernel partial least squares (KPLS) method was originally focused on soft-sensor calibration for predicting online quality attributes. In this work, an analysis of the KPLS-based modeling technique and its application ...
