steady state

Examples of steady state in the following topics:

• Steady-State Approximation

  • The steady state approximation can be used to determine the overall rate law when the rate-determining step is unknown.
  • Both cases can be addressed by using what is known as the steady state approximation.
  • With the steady state assumption, we can write the following:
  • We had no knowledge of the rate-determining step, so we used the steady state approximation for our reaction intermediate, N2O2.
  • Simplify overall rate laws using the steady state approximation for reactions with various or unknown rate-limiting steps, explainting the steady state approximation and when it is valid

• Managing the Business Cycle

  • When the economy is not at a steady state, the government and monetary authorities have policy mechanisms to move the economy back to consistent growth.
  • When the economy is not at a steady state and instead is at a point of either overheating (growing to fast) or slowing, the government and monetary authorities have policy mechanisms, fiscal and monetary, respectively, at their disposal to help move the economy back to a steady state growth trajectory.

• Phasors

  • Phasors are used to analyze electrical systems in sinusoidal steady state and with a uniform angular frequency.
  • Sinusoidal Steady State and the Series RLC CircuitPhasors may be used to analyze the behavior of electrical and mechanical systems that have reached a kind of equilibrium called sinusoidal steady state.
  • In the sinusoidal steady state, every voltage and current (or force and velocity) in a system is sinusoidal with angular frequency ω.

• Driven Oscillations and Resonance

  • The general solution is a sum of a transient solution that depends on initial conditions, and a steady state that is independent of initial conditions and depends only on the driving amplitude $\!
  • Steady state variation of amplitude with frequency and damping of a driven simple harmonic oscillator.

• Catabolic-Anabolic Steady State

• Different Types of Currents

  • This solution gives the circuit voltages and currents when the circuit is in DC steady state.
  • The solution to these equations usually contain a time varying or transient part as well as constant or steady state part.
  • It is this steady state part that is the DC solution.

• The Representation Function

  • The two-chamber structure had functioned well in state governments.
  • Two senators were chosen by state governments which benefited smaller states.
  • When the Constitution was ratified in 1787, the ratio of the populations of large states to small states was roughly 12 to one.
  • Since each state has two senators, residents of smaller states have more clout in the Senate than residents of larger states.
  • Critics, such as constitutional scholar Sanford Levinson, have suggested that the population disparity works against residents of large states and causes a steady redistribution of resources from large states to small states.

• Immigration and Border Security

  • Immigration and border security are two important issues for United States policy.
  • Illegal immigrants are those non-citizens who enter the United States without government permission and are in violation of United States nationality law or stay beyond the termination date of a visa, also in violation of the law.
  • The illegal immigrant population in the United States in 2008 was estimated by the Center for Immigration Studies to be about 11 million people, down from 12.5 million people in 2007.
  • Illegal immigrants who come generally for economic opportunities or to escape political oppression, continue to outpace the number of legal immigrants - a trend that has held steady since the 1990s.
  • Rate of immigration to the United States relative to sending countries' population size, 2001–2005

• Cutaneous Sensation

  • The somatosensory is the system of nerve cells that responds to changes to the external or internal state of the body, predominately through the sense of touch, but also by the senses of body position and movement.
  • It demonstrates a slow response and has a small receptive field; it is useful for detecting steady pressure from small objects, such as when gripping something with the hand.
  • It demonstrates a slow response and has a large receptive field; it is good for detecting steady pressure or stretching, such as during the movement of a joint.

• Principle of Diminishing Marginal Utility

  • The principle of diminishing marginal utility states that as more of a good or service is consumed, the marginal benefit of the next unit decreases.
  • The principle of diminishing marginal utility states that as an individual consumes more of a good, the marginal benefit of each additional unit of that good decreases.
  • This concept suggests a uniform steady decline of marginal utility, but that may not always be the case.
