Approaches to Dealing with More Parametric Diagnostics of Manufacturing Machines

Applied Mechanics and Materials, 2013
The contribution points out that the technical diagnosis is necessary for ensuring reliable operation. Today there is an effort to achieve maximum reliability of the machine and to plan maintenance efficiently. Technical diagnostics is basically used to monitor the status of the device.

A Parametric Comparison of Diagnostic Accuracy with Three Ordinal Diagnostic Groups

Biometrical Journal, 2007
AbstractMany medical diagnostic studies involve three ordinal diagnostic groups in which the diagnostic accuracy can be summarized by the volume or partial volume under a Receiver Operating Characteristic (ROC) surface. We study in this paper the statistical comparison of diagnostic accuracy from multiple diagnostic tests when three ordinal diagnostic ...

A New Diagnostic Model for Identifying Parametric Faults

IEEE Transactions on Control Systems Technology, 2010
This paper presents a new approach to failure detection and isolation (FDI) for systems modeled as an interconnection of subsystems that are each subject to parametric faults. This paper develops the concept of a diagnostic model and the concept of a fault emulator which are used to model and parameterize subsystem faults.

A Diagnostic Model For Identifying Parametric Faults

IFAC Proceedings Volumes, 2008
Abstract This paper considers a new approach to fault detection and isolation (FDI) for systems modeled as an interconnection of subsystems that are each subject to parametric faults. The paper develops i) the concept of a diagnostic model that parameterizes all possible subsystem faults, ii) an off-line scheme for identification of the diagnostic ...

Combining dependent tests to compare the diagnostic accuracies—a non-parametric approach

Statistics in Medicine, 2006
In this paper, we propose a non-parametric approach for comparing diagnostic accuracies in multi-reader receiver operating characteristic (ROC) studies. The approach constructs a test from each reader by extending the conventional non-parametric method and then combines all the individual test statistics to draw an overall conclusion on the relative ...

Parametric data mining and diagnostic rules for digital thermographs in breast cancer

2008 30th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2008
In this study, a novel data mining algorithm and parametric analysis protocol were utilized for generating knowledge-based diagnostic rules for infrared thermographs. First, Beier-Neely field morphing and linear affine transformation algorithms were used in geometric standardization for the whole body and partial region respectively.

Multi-resolution Image Parametrization in Stepwise Diagnostics of Coronary Artery Disease

2007
Coronary artery disease is one of the world's most important causes of early mortality, so any improvements of diagnostic procedures are highly appreciated. In the clinical setting, coronary artery disease diagnostics is typically performed in a sequential manner. The four diagnostic levels consist of evaluation of (1) signs and symptoms of the disease
