The Matsuoka oscillator has been used to control various robots that perform rhythmic movements. The oscillator-driven control system usually takes a feedback structure. While the oscillator actuates some part of a controlled object, some state variable of the object is fed back to the oscillator. An important property of this control scheme is that the oscillator comes to drive the object at i...

In this research, a new explanation and design crystal oscillator based on injection locking phenomenon is proposed. The crystal oscillator is viewed as a regular oscillator whereas is ac small input signal is its forced function. In this work, a crystal is considered to be a very small sinusoidal signal generator. To guarantee that the injection locking phenomenon is occurred the frequency of ...

the prediction of the joint angle position, especially during tremor bursts, can be useful for detecting, tracking, and forecasting tremors. thus, this research proposes a new model for predicting the wrist joint position during rhythmic bursts and inter‑burst intervals. since a tremor is an approximately rhythmic and roughly sinusoidal movement, neural oscillators have been selected to underli...

many procedures suggest for reduction of responses of riser to vortex induced vibrations (viv). natural frequencies of marine risers is an important parameter that can affect the responses of riser to viv. change of riser properties such as top tension and bending stiffness can alter natural frequencies. in this study effects of riser specifications on the responses and fatigue damage of marine...

The wien-bridge oscillator is the standard oscillator circuit for all fr...

The synchronized oscillator composed of the plural CMOS ring oscillators is interesting for improving the performances of the oscillators. Several different circuits using the CMOS ring oscillators are discussed in this report. These are the tetrahedral oscillator, ORIGAMI oscillator, precise delay generator, braided connected oscillator, and the newly proposed oscillator embedded the pincer mo...

The Silicon Physical Unclonable Function (SPUF) was first introduced by Devadas. The silicon PUF works on the basis of the variations in delays present in the gates as well as wires. The ring oscillator PUF is one of the implementation of SPUF. The ring oscillator requires one pair of ring oscillators for each output bit. So for collecting more number of output bits to acquire safe security lev...
