Designing Limit-Cycle Suppressor Using Dithering and Dual-Input Describing Function Methods

Dual function of first position nominal groups in research article titles: Describing methods and structuring summary

Previous research has identified the nominal group as the most distinctive feature of the research article title. In contrast, the findings reported in this paper suggest Theme/Rheme is the dominant structure in title text. Theme/Rheme structures order and tie nominal groups in titles. When a title starts with a methodological term the first position nominal group acts as a theme marker. Thus, ...

Limitations of the describing function for limit cycle prediction

We consider comparator-based nonlinear feedback systems, and use Tsypkin’s method to develop a strategy with which to find systems with low-pass linear part for which the describing function technique erroneously predicts limit cycles. We produce an infinite set of examples of systems with very low-pass linear parts for which the describing function technique predicts spurious limit cycles, and...

Methods for Spatiotemporal Dithering

1 flicker rates, but when the frequency is raised to 5-20 Hz, color flicker fusion occurs, where the e s flicker is seen as a variation of intensity only. Th ubject can eliminate all sensation of flicker by h p balancing the intensities of the two lights (at whic oint the lights are said to be equiluminant). When r c the intensities are not balanced, the luminance flicke an be seen at frequenci...
