unstable

Examples of unstable in the following topics:

• The Even/Odd Strategy

  • Some projects use the parity of the minor number component to indicate the stability of the software: even means stable, odd means unstable.
  • The advantage of the even/odd system, which has been used by the Linux kernel project among others, is that it offers a way to release new functionality for testing without subjecting production users to potentially unstable code.
  • The development team handles the bug reports that come in from the unstable (odd-minor-numbered) series, and when things start to settle down after some number of micro releases in that series, they increment the minor number (thus making it even), reset the micro number back to "0", and release a presumably stable package.
  • It is not the only way to get new functionality tested in the wild, however. the section called "Stabilizing a Release" describes another, perhaps more common, method of releasing potentially unstable code to the public, marked so that people have an idea of the risk/benefit trade-offs immediately on seeing the release's name.

• Collusion and Competition

  • Firms in an oligopoly can increase their profits through collusion, but collusive arrangements are inherently unstable.
  • However, collusive oligopoly is inherently unstable, because the most efficient firms will be tempted to break ranks by cutting prices in order to increase market share.

• Nuclear Fission

  • These nuclei are called unstable, and this instability can result in radiation and fission.
  • The combination of these two produces 236U, which is an unstable element that undergoes fission.
  • In nuclear fission, an unstable atom splits into two or more smaller pieces that are more stable, and releases energy in the process.
  • If U-235 is bombarded with a neutron (light blue small circe), the resulting U-236 produced is unstable and undergoes fission.

• Stability, Balance, and Center of Mass

  • When the first derivative is zero, we can take the second derivative to find whether the equilibrium is stable or unstable.
  • If the second derivative is zero or does not exist, then the equilibrium is neutral—neither stable nor unstable.
  • But if it gets pushed just slightly to the side, then it will roll down the hill with increasing speed, and the equilibrium is unstable.
  • It might have been initially "balanced" and at equilibrium, but it was an unstable equilibrium, prone to being disturbed.
  • This is an example of unstable equilibrium.

• Attribution Theory

  • Almost everyone made an A. " Such a belief suggests that the successful performance resulted from chance; the easy test is an inconsistent or unstable cause.
  • Thus, the cause of his failure is unstable, external, and uncontrollable.

• Hydrophilic and Hydrophobic Colloids

  • Since the colloid does not interact with the aqueous solvent, hydrophobic colloids are inherently unstable and generally do not form spontaneously.
  • An example of this is seen in the separation of the oil and vinegar components of vinaigrette, an unstable emulsion that will quickly separate unless shaken almost continuously.
  • In C, the unstable emulsion progressively separates.

• Kelvin-Helmholtzor Shearing Instability

  • for $g=0$ we see that if $g=0$ waves with all values of $k$ are unstable and if $g\neq 0$ for sufficiently large values of $k$ (small wavelengths), waves are unstable even if $\rho'>\rho$.
  • It turns out that even if the velocity changes gradually with position, the flow is unstable, so we would like to get a heuristic understanding of the Kelvin-Helmholtz instability.

• Nuclear Stability

  • Most odd-odd nuclei are highly unstable with respect to beta decay because the decay products are even-even and therefore more strongly bound, due to nuclear pairing effects.
  • An atom with an unstable nucleus, called a radionuclide, is characterized by excess energy available either for a newly created radiation particle within the nucleus or via internal conversion.

• Nuclear Stability

  • However, if neutron count surpasses an ideal ratio, a nucleus becomes unstable and can undergo radioactive decay.
  • Only 90 isotopes in this region are believed to be perfectly stable, while 163 more are understood to be theoretically unstable but have never been observed to decay.

• Cartel Example

  • Game theory suggests that cartels are inherently unstable, because the behavior of cartel members represents a prisoner's dilemma.
  • If monitoring is difficult, a member is likely to get away with cheating for longer; members would then be more likely to cheat, and the cartel will be more unstable.
