damp·ing

(damp'ing), Do not confuse this word with dampening.
Bringing a mechanism to rest with minimal oscillation; for example, in echocardiography, electrical or mechanical loading to reduce duration of echo, transmitter pulse, and transmitter complex.
[M.E. damp, poisonous vapor]

Patient discussion about damping

Q. Can I catch pneumonia, if I go outside with wet hair? My Mother used to tell me when I was a kid that if I go outside with wet hair, I will catch pneumonia. Is this true?

A. Are you seiously, Ann? I mean, I'm sure y're wet hair make Pneumonia?...I sorry this is not true.

Q. why is it bad to walk outside with wet hair after you have taken a shower , when it's clod out side? what can happen to me if i will do it ?

A. I've done this several times. The few times, my mother told me not to, I caught a cold.

Q. My brother is a heavy alcoholic. He has very recently been diagnosed with wet brain. My brother is a heavy alcoholic. He has very recently been diagnosed with wet brain. I am wondering what this wet brain is all about?

A. It known as Wernicke-Korsakoff syndrome also referred to as wet brain often is seen in later stage alcoholics. This condition shows up on an MRI as a smaller less functional brain. The symptoms such as short term memory loss, inability to learn new things, inability to concentrate or focus could apply to a lot of things. I have never known people actually diagnosed with this. This knowledge I gained through surfing the net.

We find that the set of a is dense, but the probability density of any [alpha] locating in this domain is small, so the existence condition of critical damping is strict.
In this case, the system oscillation is strengthened, and there is no critical damping, while it is the opposite when cos [alpha][theta] = -1; that is, [k.sub.2] is odd, so substituting cos [alpha][theta] = -1 into (6) and then (10) is obtained.
r = [square root of k[alpha]/m(2 - [alpha])], we have the minimum value of damping coefficient c which represents the critical damping coefficient cc.
Take [alpha] = 3/5, for example, the lowest point of the curve represents the critical damping point and its corresponding damping coefficient is the critical value of damping coefficient.
The second condition of critical damping is defined as [alpha] = 1.
This means that critical damping will occur at values n times larger than that of the case in which no Z-transmitter is used (or n = 1).
When the system has real poles, it means that the system has critical damping. Free vibration mode of the system is shown in Figure 8 (red line), which has obvious oscillation.
Real poles mean that the system has critical damping. Free vibration mode is shown in Figure 8 (green line); the oscillation is not obvious.
Real poles mean that the system has critical damping. Free vibration mode of the system is shown in Figure 8 (blue line); oscillation decays with time quickly.
The real pole means that the system has critical damping. It can be seen from Figure 9 that the system has dominant poles; it means that free vibration modes corresponding to conjugate poles are main modes.
However, the main conclusion from this figure is that there is no significant change if the system is lightly damped, for instance, when the fraction of critical damping is less than 5%.
