  2. Chemical stability - Wikipedia

    en.wikipedia.org/wiki/Chemical_stability

    Thermodynamic stability applies to a particular system. The reactivity of a chemical substance is a description of how it might react across a variety of potential chemical systems and, for a given system, how fast such a reaction could proceed.

  3. Stability constants of complexes - Wikipedia

    en.wikipedia.org/wiki/Stability_constants_of...

    The difference between the two stability constants is mainly due to the difference in the standard entropy change, ΔS ⊖. In the reaction with the chelating ligand there are two particles on the left and one on the right, whereas in equation with the monodentate ligand there are three particles on the left and one on the right.

  4. Steady state - Wikipedia

    en.wikipedia.org/wiki/Steady_state

    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 ...

  5. Stability theory - Wikipedia

    en.wikipedia.org/wiki/Stability_theory

    In mathematics, stability theory addresses the stability of solutions of differential equations and of trajectories of dynamical systems under small perturbations of initial conditions. The heat equation , for example, is a stable partial differential equation because small perturbations of initial data lead to small variations in temperature ...

  6. Lyapunov stability - Wikipedia

    en.wikipedia.org/wiki/Lyapunov_stability

    Instead of considering stability only near an equilibrium point (a constant solution () =), one can formulate similar definitions of stability near an arbitrary solution () = (). However, one can reduce the more general case to that of an equilibrium by a change of variables called a "system of deviations".

  7. Metastability - Wikipedia

    en.wikipedia.org/wiki/Metastability

    The stability or metastability of a given chemical system depends on its environment, particularly temperature and pressure. The difference between producing a stable vs. metastable entity can have important consequences.

  8. Root locus analysis - Wikipedia

    en.wikipedia.org/wiki/Root_locus_analysis

    Spirule. In control theory and stability theory, root locus analysis is a graphical method for examining how the roots of a system change with variation of a certain system parameter, commonly a gain within a feedback system.

  9. Numerical stability - Wikipedia

    en.wikipedia.org/wiki/Numerical_stability

    Von Neumann stability analysis is a commonly used procedure for the stability analysis of finite difference schemes as applied to linear partial differential equations. These results do not hold for nonlinear PDEs, where a general, consistent definition of stability is complicated by many properties absent in linear equations.
