Fault Detection, Diagnosis and Identification
1998In this work we distinguish between two kind of faults: slowly changing and abrupt changing faults. The first often originate from wearing and the latter from a abrupt errors within the process control system. In practice, a supervision system has to deal simultaneously with both types of faults, but here we make a distinction because different methods

Detecting Novel Classes with Applications to Fault Diagnosis
1992Existing empirical learning algorithms such as decision trees and neural networks usually measure the quality of the learned model in terms of classification error. However, as machine learning algorithms are adapted for practical applications, other aspects of classifier performance can become critically important.

Fault detection and diagnosis for operational control systems
2015 21st International Conference on Automation and Computing (ICAC), 2015Operational control for complex industrial processes consists of two layers, namely the loop control layer and the operational layer. The former realizes the required loop control for each production unit and the later determines the best set-points to the control loops in the loop control layer.

A Fault Detecting System of Intelligent Detection and Diagnosis
Advanced Materials Research, 2011By testing the running gear system with fault, the vibration signals of gear system are acquired at different speeds. Using wavelet de-noising by threshold to extract the useful feature signals, combining time-frequency analysis with intelligence detection theory of wavelet analysis, the feature signals are decomposed into different frequency bands ...

Terminology in fault detection and diagnosis
2011The following definitions are the result of a coordinated action within the IFAC Technical Committee SAFEPROCESS, published in Isermann and Balle (1997). Some basic definitions can also be found in IFIP (1983), Omdahl (1988) and in German standards like DIN and VDI/VDE-Richtlinien, see references at the end of this section and Isermann (2006).

Detection and Diagnosis of Single Faults in Quantum Circuits
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2018Detection and isolation of faults is a crucial step in the physical realization of quantum circuits. Even though quantum gates and circuits compute reversible functions, the standard techniques of automatic test pattern generation (ATPG) for classical reversible circuits are not directly applicable to quantum circuits. For faulty quantum circuits under

Fault Detection and Diagnosis for Aeronautic and Aerospace Missions
2010The term Fault Detection and Diagnosis (FDD) is a development of the term Fault Detection and Isolation (FDI). Generally speaking, FDD goes slightly further than FDI by including the possibility of estimating the effect of the fault and/or diagnosing the effect or severity of the fault.

An OOM-KBES approach for fault detection and diagnosis
1998This paper presents an integrated approach to the intelligent building research: using both the object-oriented modeling (OOM) and knowledge-based expert-system (KBES) methodologies and technologies for fault detection and diagnosis (FDD) of building HVAC systems.

Tools for fault detection and diagnosis
2008Bioprocesses play an important role in food processing, the pharmaceutical industry and in environmental management. Their underlying principles are based on inputs from chemical engineering, molecular biology, molecular genetics, physics, chemistry, mathematics, computer science and other engineering disciplines.
