Any opinions in the examples do not represent the opinion of the Cambridge Dictionary editors or of Cambridge University Press or its licensors. There are banks of storage for the waveforms, envelopes and pages. The rotary devices used offset weighting which generated sinusoidal waveforms throughout the frequency range. Effects specific to the memory and control tasks, other than the effect of probe status, were approximately canceled in these difference waveforms. The site was at once very personal, in that the waveforms reacted differently in each individual. An architecture for lossy compression of waveforms using piecewise-linear approximation. Voltage waveforms were therefore used for measuring spectra because of the more rapid data processing. The averaged evoked (or event related) potential is assumed to consist of spatially and temporally overlapping waveforms generated by different neural systems. However, grand-average waveforms can be visually deceptive and give the appearance of group differences that are not actually present. Typical temporal waveforms of the incident and reflected waves without pre-pulse. I show below representative waveforms and spectrograms of the relevant tokens. In that case, one can consider the energy and the spectral extent of the waveforms which are directly related to the modulation index. To the more advanced student, the drawing of waveforms also presents a few problems. Our spectrograms and waveforms have illustrated this type of relationship. Learning features and segments from waveforms : a statistical model of early phonological acquisition. The gray waveforms represent responses before addition of the last drug in the combination. Others were constantly looking for the most intense areas, or following the waveforms as they travelled across the floor. The complexity or presence of multiple peaks appeared to be somewhat dependent on stimulus wavelength; longer wavelength stimuli tended to produce more complex waveforms. The open triangles and filled triangles plot observers' thresholds for sawtooth test stimuli after adaptation to either rapid-on or rapid-off sawtooth waveforms, respectively. Additionally, the present results indicate that these waveforms exhibit a slight increase in amplitude until preadolescence (about age 10). In contrast to the responses to the achromatic stimuli, these waveforms do not exhibit a single prominent component at a specific latency. Finally, at the highest speeds the waveforms merge into the pattern offset-onset response. Thus, we obtained nine response data sets, each with estimated elementary waveforms for the eight regions for each eye. The black waveforms represent responses of the inner regions of lower visual field, which are triphasic. See text for description of waveforms 3- 4. To that end we fitted the standard three-component, two-lag model to sets of responses waveforms from each stimulus region and eye!. Occasionally, the maximum and minimum amplitude values do not bracket the grand average amplitude as a result of phase variations in the contributing waveforms. To compare the offset responses, the waveforms were aligned at stimulus offset. The difference waveforms are negative in polarity, with an initial oscillatory component. Responses of macaque ganglion cells and human observers to compound periodic waveforms. Displayed traces are average waveforms of five consecutive recordings obtained from the same cell. The recordings of the highest peak velocity were selected for deriving the mean and maximal instantaneous gradients and averaged from 3 to 5 waveforms. The compound grating consists of red and green raised cosine waveforms. Figure 9 displays the contrast between unrelated-minus-related probe difference waveforms for the memory and control tasks. Shapes go all the way down to, for example, waveforms of light. They also showed that poor cognitive progress at 2 years was more strongly associated with fetal heart rate abnormalities than with abnormal umbilical artery waveforms. The current waveforms in our experiment are not able to fit to an analytic function accurately. Representative waveforms and spectrograms of the ejective clusters are shown below in 5.1, but their measurements are not included in the statistics. The drawn waveforms pass over photocells, illuminated from above by a steady stream of light, to the right of the flat surface. When the waveforms of the pulses were resolved in the time domain, it was recognized that they were most probably coherent nonlinear structures [1, 2]. The data points of the figure represent the intervals at which the voltage waveforms were analyzed. Figure 2 shows the oscilloscope traces of the typical incident and reflected waveforms at several incident energies. Another parameter of interest is the thickness of the insulating coating for optimal expansion of a wire for given pulser current and voltage waveforms. The secondary voltages are stacked and synthesized to make designed waveforms, for example, as required in an induction acceleration unit. The square plots below the rasters show the spike waveforms and the quality of spike isolation. The grey waveforms are for all other regions, and are generally biphasic. Additionally, latencies of the components in the infant waveforms do not coincide with adult latencies. Both responded with sinusoidal waveforms whose amplitude varied linearly with modulation depths ranging up to 7-8%. Adequacy of isolation was also monitored by display of detected spike waveforms on a digital oscilloscope with delayed triggering. In this regard, the stereotypical regenerative waveforms in isolated bipolar cells might serve as a model for such studies. The waveforms obtained from both subjects under cone isolating conditions were similar. Reconstructed waveforms across the five channels for adults and infants comparing rotation, translation, and expansion motion patterns. Horizontal brackets and numerals indicate consecutive flashes averaged to produce the waveforms shown in the bottom panel. The k 1 waveforms contained marginally significant coefficients at a rate expected by chance. Each trace is the average over all five cycles for 50 trials, hence, is an average of 250 waveforms. Three waveforms are illustrated for each subject; each is the average of four consecutive sweeps. There were some differences in amplitudes, most markedly for the left and right temporal gyrus waveforms in the postsentence retention interval. The beginning and end of each vowel token was identified by inspection of wide-band spectrograms and time domain waveforms. Death of one twin followed by extremely variable -ow velocity waveforms in the surviving fetus. Decreased vascularization and cell proliferation in placentas of intrauterine growth-restricted fetuses with abnormal umbilical artery flow velocity waveforms. The appearance of biphasic and negative waveforms between contractions may potentially be a useful marker for the development of severe fetal decompensation. As shown, the current waveforms of all wires have two peaks. Using vibro-acoustic energy as the working medium, the project investigated the unique properties of low-frequency waveforms as they affect structures and people simultaneously. Durational measurements were made using broadband spectrograms and aligned waveforms. The magnitude and duration time of the measured waveforms don't change while the diplexer is employed. The frequency of the occurrence of a release burst was reported, based on waveforms and wideband spectrograms. When comparing waveforms between subjects, time-to-peak values representative of the group of subjects have been used. However, our recordings with larger stimuli resulted in more distinct differences between low- and high-contrast waveforms. Both spectral analysis and the reconstructed waveforms suggest that evoked responses to expansion flow patterns differ from those evoked by contraction. Each graph was computed by synthesizing waveforms from the first 10 components of the coherently averaged spectrum. Stimulus waveforms were generated by a computer through 12-bit digital-to-analog converters. In this study, these complex waveforms were not examined. Each panel represents the waveforms superimposed for all regions, for the grand mean responses across the 13 subjects. To address this possibility, we derived the subjects' response amplitude on each cycle of the individual waveforms. With deprived-eye stimulation, activation of the retinotopic locus of the recording site elicited transformed local field potentials with abnormal waveforms and long response latencies. The waveforms are plotted with the youngest subject's response (age 2) appearing at the bottom of the figure. The indices of chromatic selectivity for the chromatic onset waveforms are plotted against field size. Similar to the temperature modulation, the waveforms and steady-state levels of emissions also vary with the modulation schemes. Note the crisscrossing of the current waveforms, which indicates the acceleration in the inactivation kinetics that accompanies the current potentiation. According to real current waveforms, the pinch process is simulated. The response of macaque retinal ganglion cells to complex temporal waveforms. A 100-channel system for real time detection and storage of extracellular spike waveforms. The main point of this paper is to describe the simplest, in a sense, nonlinear vacuum process: the interaction of two electromagnetic waveforms propagating in opposite directions. Foetal umbilical artery flow velocity waveforms and placental resistance : clinical significance. The areas of the inward currents were calculated from the negative portion of the waveforms between 0 and 9 sec, 0 sec being defined as the beginning of stimulation. Differences in these waveforms between a group of 35 maltreated and 24 nonmaltreated children were reported. Reliable velocity waveforms were obtained in 91% of cases. The brain's ceaseless electrical activity showed characteristic waveforms that varied with sleep and wakefulness, mental activity or tranquillity. Venous waveforms in the inferior vena cava and ductus venosus are triphasic with peaks corresponding to maximum systolic velocity, maximum diastolic velocity and atrial systole. The present results provide evidence that development of waveforms to low spatial-frequency achromatic reversal and chromatic onset stimuli follow different time courses. In contrast, infants' evoked response waveforms to all flow types were equivalent, and showed no evidence of the expansion0contraction asymmetry. The result is not unexpected because response waveforms tend to differ most at these longer latencies at all contrasts and temporal conditions. The waveforms were evaluated at the five backgrounds, in response to contrasts of 60.07, 60.30, and 61, for all 111 cells in the present sample. The naso-temporal comparison shows smaller and more similar waveforms for the more affected as compared to control and less affected patient. The current waveforms and the evolution of the plasma radius are shown in these figures. In addition to (and independently of) the quantitative analysis, each token was categorized by allophonic category using waveforms and spectrograms. There was one r 2 -value for each of the 736 response waveforms indicating how well the models accounted for the variance in each response. The timing generator is responsible for producing two timing waveforms. The waveforms show that for the overall system the faster the motor turns, the faster the solar tracking unit can return to its original position. Response waveforms were corrected for this delay, and also corrected regionwise for the progressive delay caused by the raster scan down the monitor screen.
