3D tomographic images are used by the Schneider Electric Company to assess the quality of composite materials. These images bring information on the internal organization of the parts. Several image classification methods were applied to detect the orientated and the isotropic regions within the image. This paper presents the fusion of these partial classifications by means of the decision templates method proposed by L. Kuncheva. An adaptation of the initial method is proposed to manage the class of reject for which it is not possible to learn a decision template. Obtained detections are assessed by the confusion matrix whose results show the effectiveness of the approach

Representation of multi-winding transformers by equivalent circuits has been recently improved and so it is for the identification of its components. In this paper, focus is on magnetic coupling with its related losses. A general method, based on impedance measurements, is used to determinate inductances, coupling ratio and resistances included in these equivalent circuits. Justification for impedance measurements, choice of measured impedances and precautions regarding short-circuit compensation are discussed. For illustration, two components are tested and their equivalent circuits are established

Presented in this paper is a new flame monitor that uses three photovoltaic cells covering UV, visible and IR spectral bands respectively. A gain adjustable amplifier is incorporated into the monitor so that it is applicable to coal, oil or gas fired flames. Self-checking of the monitor is implemented through cross-correlation of the signals from the three cells and hence no additional self-checking hardware is required. Both flickering frequency and brightness of the flame are determined to monitor flame stability and to detect flame presence as well as sighting tube blockage. Unlike conventional single cell flame detectors, the new multi-cell device can still be in operation before being repaired after a cell-failure alarm has gone off. Experiments carried out on an industrial scale combustion test facility demonstrate the advantages of the new flame monitor over conventional flame detectors

A novel filter for use in three-phase power systems is introduced. When the input to the filter is a three-phase balanced set of signals, the filter suppresses noise and distortions and extracts a smooth version of the fundamental components. When the input signal to the filter is unbalanced, it extracts the positive-sequence components of the input signal. The filter also estimates the magnitude, phase-angle and frequency of the input signal while adaptively accommodates variations in all these three variables. Characteristics of the filter including its mathematical equations as well as steady-state and dynamic responses are discussed in this paper. Structural simplicity and robustness of the filter make it desirable for power system application. It can specifically be used as an adaptive anti-aliasing filter

In this paper, we proposed a technique based on random fuzzy approach for the calibration of a virtual instrument (VI). This technique is based on Yager triangular norm and is used to describe measurement uncertainty (both random and systematic effects, as seen in (Urbanski and Wasiwsky, 2003)) in a simple and quite fast way. The whole measurement chain is not totally treated as a black box, because manufacturer's specifications for conversion and transducer system are used to determine the uncertainty propagation in measurements performed by the VI of (De Capua et al., 2004)

This paper presents an analytical model which describes the inductance change when a double air-cored coil sensor is placed next to a conducting plate. Analysis of the analytical model reveals that the phase signature of such sensor is virtually lift-off independent. This finding is verified by numerical evaluations. This paper also finds that the phase signature of a ferrite U-cored sensor can be approximated by that of a double air-cored sensor of similar size, and therefore possesses similar lift-off independent property. Measurements made with a sample U-cored sensor next to plates of non-magnetic and magnetic materials verified the theoretical results

The development and implementation of a digital signal processor (DSP) based portable impedance measurement instrument is described in this paper. The circuit sinewave stimulus is generated by the device using a direct digital synthesizer at the desired measurement frequency. The sine is applied to a reference impedance in series with the unknown impedance. Two analog to digital converters (ADCs) acquire multiple samples of the two sine voltages which are transmitted to the DSP. Sine-fitting algorithms determine the sine amplitudes, phases, DC components and frequency. From these values and the reference impedance values, the impedance amplitude and phase are determined. Included in the device, amplifiers extend the ADCs input range while a digital potentiometer enables the adjustment of the reference impedance to improve accuracy

We present a system allowing the determination of the distribution of light at any given distance (e.g. 25m) from a light source, by measuring the intensity and direction of the illumination distribution at a closer distance (e.g. near 20 cm). The measurement principle is based on the acquisition of images taken by a CCD matrix-sensor through an optical system focused at infinity. A sequence of images is obtained by moving the camera at different positions in front of the source. The process involves the accumulation of shifted images and corrections for optics (geometrical distortion and vignetting) and electronic shutter (exposure time). We describe the developed experimental set-up and the calibration procedures needed to obtain absolute photometric values. We present results obtained for automotive headlamps: computed relative illumination distribution is very similar to that obtained using a reference given by a measurement tool using a lightmeter. Absolute calibration of the system is performed from the set of measured points

In this paper, a novel approach is presented to the measurement of velocity and mass flow rate of pneumatically conveyed fine particles using electrostatic sensing and neural network techniques. A single ring-shaped electrostatic sensor is used to obtain a signal from which the two crucial parameters, velocity and mass flow rate of particles, may be derived for the purpose of monitoring and control. It is found that the quantified characteristics of the signal are related to the velocity and mass flow rate of particles. The relationships between the signal characteristics and the two measurands are established through the use of a back-propagation (BP) neural network. Results obtained on a laboratory test rig suggest that an electrostatic sensor in conjunction with a trained neural network may provide a simple, practical solution to the long standing industrial measurement problem
