    This paper explores the effect of diffraction on estimates of the spectra of signals reflected from interfaces located at a given range from the transducer. When an ultrasound pulse is transmitted into a medium, the power spectra of reflected signals vary as a function of range from the transducer. These spectral changes are caused by diffraction effects, due to the finite-sized aperture, and by t... View full abstract»

  • Finding the Site of Origin and Velocity of Propagation in a Short One-Dimensional Strand from Two Extracellular Waveforms

    In cardiac muscle times of excitation, the site of origin of excitation and propagation velocity usually are determined from the intrinsic deflections of a collection of extracellular waveforms. Separate waveforms are measured from each site for which an excitation time is to be found. Most of the information in each measured waveshape is discarded, even though waveshape features have been shown t... View full abstract»

  • A Comparison Between Walsh and Fourier Analysis of the Electroencephalogram for Tracking the Effects of Anesthesia

    The effects that anesthesia has on the surgical patient can be characterized with the electroencephalogram (EEG). These effects are typically quantified through frequency analysis of the EEG signal. The fast Fourier transform (FFT) is usually employed for this purpose. In recent years, the fast Walsh transform (FWT) has been proposed as an alternative to the FFT for signal analysis because it is c... View full abstract»

  • Ceramic Electrodes for ELF Bioeffects Studies

    Whenever metal electrodes are used for chronic exposure of biological material to ELF electric fields in a liquid medium, there is a possibility that observed effects are caused directly by ions from the electrodes rather than by the electric field. The problem can be avoided by using insulated electrodes, but ordinarily this severely limnits the fields which can be obtained in the medium. We show... View full abstract»

  • Psychophysical Response to Electrocutaneous Stimulation

    A method is presented to determine a reliable stimulus-sensation relationship particularly suitable for electrocutaneous stimulation. An experimental intensity-discrimination curve was obtained through simple psychophysical comparison tasks, and sensory response was inferred from integration of a JND's density function. The psychophysical response resembles a power law, although departures cannot ... View full abstract»
