Yates says Atlanta has come a long way since the '70s. But Silicon Valley has several key advantages: easy access to capital and a network of seasoned entrepreneurs. And, Yates says: Maybe this is a cultural difference in the rest of the world versus the Valley, but it's the idea that in the Valley, it's OK to fail.
The angular frequency is measured in radians per second. The inverse of the period is the frequency f = 1/T. The frequency f = 1/T = Ï/2Ï of the motion gives the number of complete oscillations per unit time. It is measured in units of Hertz, (1 Hz = 1/s).
The phase oscillator. A phase oscillator is an oscillator model where we view the state of the system as going around the simplest loop, a unit circle. In a phase oscillator model, the state variable $\theta$ is called the phase of the oscillator. The state space in which the phase $\theta$ lives is the interval $[0, 2\pi]$.
