What is meant by the term steady state of concentration of ozone in stratosphere?
Steady state of concentration of ozone means no change in its concentration. It maintains the level to be accurate.
Is there a dynamic steady state of ozone in the stratosphere?
yes
If a population of bacteria is in steady state does that mean no bacteria are dying?
no
What discovery destroyed the steady state theory?
For most cosmologists, the refutation of the steady-state theory came with the discovery of the cosmic microwave background radiation in 1965, which was predicted by the Big Bang theory
Is the steady state a theory o a fact?
The Steady State theory is now an obsolete theory. It was an interesting alternative to the normal Big Bang theory, but it doesn't agree with observations.The Steady State theory is now an obsolete theory.

What is along and digital control system?
A: The last time that i kept up with types of systems there were only three what is along?. Well anyhow type-0 system is one that requires a constant error signal to operate type-1 a constant rate of change of the controlled variable requires a constant error signal under steady state condition. type 1 is usually referred as servomechanism system. type-2 a constant acceleration of the control variable requires a constant error under steady state condition. type-2 sometimes is referred to as zero velocity error system
Steady state gain of the system?
Steady state gain,
What is dynamic error coefficients in control system?
static error coefficients are the error calculated when steady state is reached. so, the dynamic error coefficients give the error calculated with time. it just calculated by taking the inverse Laplace transform of E(s) term resulting in the equation: e(t)=k0 r(t) + k1 r('t) + k2 r''(t) + ... where, k0: position error coefficient k1: velocity error coefficient k2: acceleration error coefficient sks..
What is the use of PD controller?
Proportional-Derivative control is useful for fast response controllers that do not need a steady-state error of 0. Proportional controllers are fast. Derivative controllers are fast. The two together is very fast. Below is a review.Proportional Action[1]Proportional action provides an instantaneous response to the control error. This is useful for improving the response of a stable system but cannot control an unstable system by itself. Additionally, the gain is the same for all frequencies leaving the system with a nonzero steady-state error. Derivative Action[2]Derivative action acts on the derivative or rate of change of the control error. This provides a fast response, as opposed to the integral action, but cannot accomodate constant errors (i.e. the derivative of a constant, nonzero error is 0). Derivatives have a phase of +90 degrees leading to an anticipatory or predictive repsonse. However, derivative control will produce large control signals in response to high frequency control errors such as set point changes (step command) and measurement noise. In order to use derivative control the transfer functions must be proper. This often requires a pole to be added to the controller (this pole is not present in the equations below).

Is homeostasis and human biology relevant?
Yes it is Homeostasis involves the bodys systems combating a stimulus the body returns the systems to its optium state and creaetes a steady state it does this by using the feedabck system Yes it is Homeostasis involves the bodys systems combating a stimulus the body returns the systems to its optium state and creaetes a steady state it does this by using the feedabck system Yes it is Homeostasis involves the bodys systems combating a stimulus the body returns the systems to its optium state and creaetes a steady state it does this by using the feedabck system
What is the difference between feedback control and feedback measurement system?
In feedback measuring system • indication is fedback via inverse transducer, •compared with measurand and •moves on to new steady state till error is reduced to zero. Feedback control system controls relatively high power through actuator. Feedback measuring system is drawing fairly low power devices at output (indicators, inverse transducer). Feedback in measuring system•Improves accuracy in measurement •Improves Speed of measurement •Allows remote indication •Allows noncontact measurement BUT•Increases complexity of design, operation, size and cost
What is the difference between regulatory control system and servo system?
A servo control loop is one which responds to a change in setpoint. The setpoint may be changed as a function of time (typical of this are batch processes), and therefore the controlled variable must follow the setpoint.and,A regulatory control loop is one which responds to a change in some input value, bringing the system back to steady state. Regulatory control is by far more common than servo control in the process industries.
