  • The irregular trend in integrated series is known as a stochastic trend as opposed to a simple linear deterministic time trend.

    Energy quality

  • It seems farfetched, but it's based on a physical principle called stochastic resonance.

  • Pearle's approach requires the precise formulation of the idea of stochastic Lorentz invariance.

  • Alexander develops the notion of stochastic technê further in his commentary on Aristotle's Topics.

    Episteme and Techne

  • He calls stochastic, then, the sorts of technê whose task is to try everything possible to achieve their goal, the realization of the goal being subject to chance.

    Episteme and Techne

  • This is analogous to a paradoxical physical phenomenon known as stochastic resonance, in which an increase in noise enhances the detection of weak signals.

    ENTANGLED MINDS

  • However, it was shown that the correction of the fluctuation of the average position of a great many particles was sufficient to produce a cooling effect, hence the name stochastic cooling.

    Accelerators and Nobel Laureates

  • From a technical analysis viewpoint, KASB Securities analyst Aiyaz Hassan said gold's so-called stochastic oscillator - an indicator of momentum in prices - has generated a buy signal for the precious metal.

  • work encompassed by the "stochastic arts"--those that "diagnose and fix things that are variable, complex, and not of our own making." He includes in this category mechanics and medical practitioners and those with other occupations which, because of the constant risk of failure, at least potentially prevent self-absorption, and instead "cultivate not creativity, but the less glamorous virtue of attentiveness"

  • Funny, this came up when I was 'randoming.'
