    A method for the allocation of responsibilities between a utility and a consumer, with reference to the distortion of three-phase voltage waveforms at the point of common coupling (PCC), has been presented. The input data required for applying this method are the measured voltage and current waveforms at the PCC. The frequencies in the measured waveforms are estimated, and a Kalman filter is used ...

    This paper presents a novel training method for estimating the parameters of retina models, such as integrate-and-fire (IF) or Poisson based. The presented models are constructed using a set of linear and nonlinear filters, which are described by basis functions and Taylor polynomials, respectively. This approach allows for the identification of a set of features that can be used for reproducing r... View full abstract»

  • In Vivo Blood Characterization From Bioimpedance Spectroscopy of Blood Pooling

    Publication Year: 2009, Page(s):3831 - 3838

    Characterization of blood impedance properties is important to estimate clinical diagnostic indexes such as hematocrit, glucose level, and hydration. Current in vivo bioimpedance spectroscopy methods are performed on a body appendage and thus represent a combined measurement of all tissues in the measurement field, rather than the blood individually. This paper describes a novel in vivo measuremen... View full abstract»

  • A Precise Analysis of the IEC Flickermeter When Subject to Rectangular Voltage Fluctuations

    Publication Year: 2009, Page(s):3839 - 3846

    The Pst measured using the International Electrotechnical Commission (IEC) flickermeter for a rectangular fluctuation is discontinuous for certain values of the frequency of fluctuation. These discontinuities do not represent a real physiological perception of flicker, but they are a consequence of the nonlinear behavior of blocks 1, 4, and 5 of the IEC flickermeter. We have theoretical... View full abstract»

  • The Histogram Test of ADCs With Sinusoidal Stimulus Is Unbiased by Phase Noise

    Publication Year: 2009, Page(s):3847 - 3854

    This paper intends to show that the presence of normally distributed phase noise or jitter in the test setup or in the analog-to-digital converter (ADC) itself does not cause a bias in the sinusoidal histogram test estimation of the transfer function of an ADC. The analytical proof presented demonstrates that there is no need to use an extra overdrive when stimulating the ADC, as is the case with ... View full abstract»

  • An Improved Super-Resolution Source Reconstruction Method

    Publication Year: 2009, Page(s):3855 - 3866

    The source reconstruction method (SRM) is a technique developed for antenna diagnostics and for carrying out near-field (NF) to far-field (FF) transformation. The SRM is based on the application of the electromagnetic equivalence principle, in which one establishes an equivalent current distribution that radiates the same fields as the actual currents induced in the antenna under test (AUT). The k... View full abstract»

  • The Quality of Lagged Products and Autoregressive Yule–Walker Models as Autocorrelation Estimates

    Publication Year: 2009, Page(s):3867 - 3873
    Cited by:  Papers (2)

    The sample autocorrelation function is defined by the mean lagged products (LPs) of random observations. It is the inverse Fourier transform of the raw periodogram. Both contain the same information, and the quality of the full-length sample autocorrelation to represent random data is as poor as that of a raw periodogram. The autoregressive (AR) Yule-Walker method uses LP autocorrelation estimates... View full abstract»

  • Jitter Measurement and Compensation for Analog-to-Digital Converters

    Clock jitter is measured and digitized by a stochastic time-to-digital converter (TDC). This jitter information is used to compensate the sampling error of an analog-to-digital converter (ADC) caused by the clock jitter. The following two system scenarios are covered: 1) an ADC with a clean external clock and 2) an ADC with an external clock as the main jitter source. TDC calibrations for b... View full abstract»

  • Particle Filtering for State Estimation in Nonlinear Industrial Systems

    State estimation is a major problem in industrial systems, particularly in industrial robotics. To this end, Gaussian and nonparametric filters have been developed. In this paper, the extended Kalman filter, which assumes Gaussian measurement noise, is compared with the particle filter, which does not make any assumption on the measurement noise distribution. As a case study, the estimation of the... View full abstract»

  • On the Calibration of DA Converters Based on $R/beta R$ Ladder Networks

    In this paper, we discuss the possibility of realizing high-accuracy digital-analog(DA) converters by exploiting the properties of R/betaR (beta > 2) ladder networks. Extensive simulations demonstrate that, if a proper value of beta is chosen, high accuracy can be obtained by resorting to a very simple self-calibration algorithm. This is true, even in the case of large tolerance values for the ... View full abstract»

  • Inductive Sensor for Measuring High Frequency Partial Discharges Within Electrical Insulation

    Partial discharges are not only a consequence but a symptom of insulation degradation in electrical equipment. Partial discharges are revealed outside the insulation as very narrow high-frequency pulses that were superimposed to the grid frequency high-level voltages or currents and thus are fairly hard to detect. This paper presents an application of a new inductively coupled sensor that allows t... View full abstract»

  • Current-Mode Capacitive Sensor Interface Circuit With Single-Ended to Differential Output Capability

    This paper presents a current-mode interface circuit for capacitive sensors, with the main features being its ability to produce a differential output from a single-ended sensor (using a fixed reference capacitor) and its simplicity in realization. These advantages make it a potential candidate for applications where differential sensors are not available and where a simple design is required. The... View full abstract»
