The balance of nature, also known as ecological balance, is a theory that proposes that ecological systems are usually in a stable equilibrium or homeostasis, which is to say that a small change (the size of a particular population, for example) will be corrected by some negative feedback that will bring the parameter back to its original "point of balance" with the rest of the system.
Limits of Stability (LoS) is a significant variable in assessing stability and voluntary motor control [6] in dynamic states. [7] It provides valuable information by tracking the instantaneous change in the center of mass (COM) velocity and position. [7]
Hegemonic stability theory (HST) is a theory of international relations, rooted in research from the fields of political science, economics, and history.HST indicates that the international system is more likely to remain stable when a single state is the dominant world power, or hegemon. [1]
In sociology, a system is said to be in social equilibrium when there is a dynamic working balance among its interdependent parts. [1] Each subsystem will adjust to any change in the other subsystems and will continue to do so until an equilibrium is retained. The process of achieving equilibrium will only work if the changes happen slowly.
Steady State Stability studies are restricted to small and gradual changes in the system operating conditions. In this we basically concentrate on restricting the bus voltages close to their nominal values. We also ensure that phase angles between two buses are not too large and check for the overloading of the power equipment and transmission ...
The stability–instability paradox is an international relations theory regarding the effect of nuclear weapons and mutually assured destruction.It states that when two countries each have nuclear weapons, the probability of a direct war between them greatly decreases, but the probability of minor or indirect conflicts between them increases.
Since Newton's law of gravitation (1687), mathematicians and astronomers (such as Laplace, Lagrange, Gauss, Poincaré, Kolmogorov, V. Arnold, and J. Moser) have searched for evidence for the stability of the planetary motions, and this quest has led to many mathematical developments and several successive "proofs" of stability of the Solar System.
Bifurcation theory is a useful way to study the stability of a given flow, with the changes that occur in the structure of a given system. Hydrodynamic stability is a series of differential equations and their solutions. A bifurcation occurs when a small change in the parameters of the system causes a qualitative change in its behavior,. [1]
