  2. Steady-state model - Wikipedia

    en.wikipedia.org/wiki/Steady-state_model

    In cosmology, the steady-state model or steady-state theory is an alternative to the Big Bang theory. In the steady-state model, the density of matter in the expanding universe remains unchanged due to a continuous creation of matter, thus adhering to the perfect cosmological principle , a principle that says that the observable universe is ...

    The steady state approximation, [1] occasionally called the stationary-state approximation or Bodenstein's quasi-steady state approximation, involves setting the rate of change of a reaction intermediate in a reaction mechanism equal to zero so that the kinetic equations can be simplified by setting the rate of formation of the intermediate equal to the rate of its destruction.

  4. List of superseded scientific theories - Wikipedia

    Static Universe theory [14] Steady state theory, a model developed by Hermann Bondi, Thomas Gold, and Fred Hoyle whereby the expanding universe was in a steady state, and had no beginning. It was a competitor of the Big Bang model until evidence supporting the Big Bang and falsifying the steady state was found.

  5. Steady state - Wikipedia

    en.wikipedia.org/wiki/Steady_state

    In systems theory, a system or a process is in a steady state if the variables (called state variables) which define the behavior of the system or the process are unchanging in time. In continuous time , this means that for those properties p of the system, the partial derivative with respect to time is zero and remains so:

  6. Dynamic equilibrium (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Dynamic_equilibrium

    In a new bottle of soda, the concentration of carbon dioxide in the liquid phase has a particular value. If half of the liquid is poured out and the bottle is sealed, carbon dioxide will leave the liquid phase at an ever-decreasing rate, and the partial pressure of carbon dioxide in the gas phase will increase until equilibrium is reached.

  7. State-space representation - Wikipedia

    en.wikipedia.org/wiki/State-space_representation

    State-space models are applied in fields such as economics, [3] statistics, [4] computer science, electrical engineering, [5] and neuroscience. [6] In econometrics , for example, state-space models can be used to decompose a time series into trend and cycle, compose individual indicators into a composite index, [ 7 ] identify turning points of ...

  8. Process simulation - Wikipedia

    en.wikipedia.org/wiki/Process_simulation

    Steady-state models perform a mass and energy balance of a steady state process (a process in an equilibrium state) independent of time. Dynamic simulation is an extension of steady-state process simulation whereby time-dependence is built into the models via derivative terms i.e. accumulation of mass and energy.

  9. Examples of Markov chains - Wikipedia

    The next state of the board depends on the current state, and the next roll of the dice. It does not depend on how things got to their current state. In a game such as blackjack, a player can gain an advantage by remembering which cards have already been shown (and hence which cards are no longer in the deck), so the next state (or hand) of the ...
