Decomposition of time-scale (frequency) activities from a randomly selected single trial in response to a duration deviant stimulus in a schizophrenia patient, using 8-level bio5.5 discrete wavelet. Note that this graph is a technical illustration only: single trial data vary greatly from trial to trial. Time 0 indicates the onset of the duration deviant stimulus. Activities from 25 to 275ms were extracted for calculation of power (PSD). The y-axis is scaled differently in different detail scales in this illustration. There were no discernable evoked oscillatory signals that could be easily observed from the original single trial recording (top). With the discrete wavelet transform, it appeared that very small but discernable energy changes might have appeared at detail level D3 (85–150Hz), D6 (12–20Hz), D7 (5–12Hz), and D8 (1–5Hz), as marked by the red ovals. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.) ... Oscillations

Natural frequency... Top: The Evripos (central Greece) cable bridge. An arrow indicates the position where the RTS reflector was fixed (midspan). Bottom: Spectrum of the recorded height changes at the midspan using RTS. The peak at around 0.56 Hz corresponds to the 4th modal frequency of bridge (0.552 Hz, FEM-derived value). Frequencies frequency of the bridge 0.362 Hz [13]. Interestingly, noise in the RTS recordings and the assumption of equidistant data have probably concealed some of the dominant frequencies, but still one of them is clearly shown (modified after Lekidis et al. [13]). ... (a) Cartoon to explain the measurement of the pendulum oscillation. Left, vertical section; right plan view, showing three points from which measurements were made. (b) Graph of a part of an oscillation recorded from site 1. (c) Graph of the oscillation from site 3 in perspective form. The oscillation trajectory is also projected in the x–y plane. (d) An example of poorly recorded oscillation in the case of a target with a high linear (> 15 cm/s) or angular (approximately 10–15∘/s) velocity. ... Oscillation... Time series of x, y and z axes of a representative oscillation experiment (left) and the corresponding spectrograms (right). The time series of the x axis describe accurately the oscillation amplitude (2 cm) and the corresponding spectrogram defines the oscillation frequency (1 Hz). Measurement noise in the y and z axes is ±2 mm and ±0.5 mm, respectively, and can be classified as white noise. ... RTS timeseries describing the wagon displacement during selected experiments. Horizontal lines indicate the real oscillation amplitude, preset in the device and confirmed by independent optical observations. The input (real) oscillation frequency is indicated in each diagram. Note the accurate determination of the oscillation amplitude. The arrows indicate parts of the time series where the maximum amplitude of the oscillation could not be recorded due to the limited recording frequency relatively to the oscillation frequency. Approximate maximum velocities for a:6, b:16, c:20, d:24, e:29, f: 12.5 cm/s. ... Comparison of the oscillation frequency of the pendulum predicted from the basic formula (standard error computed from the law of propagation of errors [15]) and spectral analysis of RTS data for two cord lengths
