  2. Frequency of exceedance - Wikipedia

    en.wikipedia.org/wiki/Frequency_of_exceedance

    Thus, the mean time between peaks, including the residence time or mean time before the very first peak, is the inverse of the frequency of exceedance N −1 (y max). If the number of peaks exceeding y max grows as a Poisson process, then the probability that at time t there has not yet been any peak exceeding y max is e −N(y max)t. [6] Its ...

  3. Particle aggregation - Wikipedia

    en.wikipedia.org/wiki/Particle_aggregation

    Adsorption of oppositely charged species (e.g., protons, specifically adsorbing ions, surfactants, or polyelectrolytes) may destabilize a particle suspension by charge neutralization or stabilize it by buildup of charge, leading to a fast aggregation near the charge neutralization point, and slow aggregation away from it.

  4. Buffered probability of exceedance - Wikipedia

    en.wikipedia.org/wiki/Buffered_probability_of...

    The bPOE is the probability of a tail with known mean value . The figure shows the bPOE at threshold x {\displaystyle x} (marked in red) as the blue shaded area. Therefore, by definition, bPOE is equal to one minus the confidence level at which the Conditional Value at Risk (CVaR) is equal to x {\displaystyle x} .

  5. Probability distribution fitting - Wikipedia

    en.wikipedia.org/wiki/Probability_distribution...

    An estimate of the uncertainty in the first and second case can be obtained with the binomial probability distribution using for example the probability of exceedance Pe (i.e. the chance that the event X is larger than a reference value Xr of X) and the probability of non-exceedance Pn (i.e. the chance that the event X is smaller than or equal ...

  6. Smoluchowski coagulation equation - Wikipedia

    en.wikipedia.org/wiki/Smoluchowski_coagulation...

    This diagram describes the aggregation kinetics of discrete particles according to the Smoluchowski aggregation equation. In statistical physics, the Smoluchowski coagulation equation is a population balance equation introduced by Marian Smoluchowski in a seminal 1916 publication, [1] describing the time evolution of the number density of particles as they coagulate (in this context "clumping ...

  8. Cumulative frequency analysis - Wikipedia

    en.wikipedia.org/wiki/Cumulative_frequency_analysis

    Cumulative frequency is also called frequency of non-exceedance. Cumulative frequency analysis is performed to obtain insight into how often a certain phenomenon (feature) is below a certain value. This may help in describing or explaining a situation in which the phenomenon is involved, or in planning interventions, for example in flood ...

  9. Tail value at risk - Wikipedia

    en.wikipedia.org/wiki/Tail_value_at_risk

    The former definition may not be a coherent risk measure in general, however it is coherent if the underlying distribution is continuous. [4] The latter definition is a coherent risk measure. [3] TVaR accounts for the severity of the failure, not only the chance of failure. The TVaR is a measure of the expectation only in the tail of the ...
