The frequency-amplitude (F-A) curve has been proposed to characterize the electromechanical oscillation frequency of a single-machine-infinite-bus (SMIB) system considering nonlinearity of the swing ...

For the sum of bounded deterministic signals, the behavior of the peak-to-RMS ratio as a function of the number of addends isn’t as clear. One case of interest is the sum of sinusoids of various ...

A higher amplitude of vibration at harmonics of the fundamental frequency (1X) indicates faulty conditions such as unbalance, misalignment, and a bent shaft. However, misalignment issues and bent ...

The team looked at data on their bowel movement frequency collected between 2012 and 2013, as well as self-assessments of cognitive function from 2014 to 2017 and cognitive assessments taken ...

A design idea with a 555 analog timer that can generate an arbitrary triangle/sawtooth with its waveshape and frequency controlled by pots. If you could assemble the list of all the oscillators that ...

The MIJIA Front-loading Washing Machine 12kg comes with a decent 12kg capacity that can easily meet the cleaning needs of a family of four or five. It can be used to wash up to five sets of four ...

The measurement of this network is shown in Figure 6. On the top are the frequency graphs and on the bottom are the TDR graphs. The S11 Smith chart in the top portion of the figure looks like before.

1. Here’s the setup of a simple network measurement of a length of 50-Ω coax terminated with a short. Measurement results are provided in Figure 2. The graphs in Figure 2 are all different ...
