Alpha Stable Distribution Based Morphological Filter for Bearing and Gear Fault Diagnosis in Nuclear Power Plant
Published 2015-01-01“…The length of structuring element (SE) of dilation-erosion gradient filter is optimized by alpha stable distribution. Method experimental verification confirmed that parameter alpha is superior compared to kurtosis since it can reflect the form of entire signal and it cannot be influenced by noise similar to impulse.…”

Lévy walk of pions in heavy-ion collisions
Published 2025-02-01“…Utilising Monte-Carlo simulations of high-energy collisions, we show that the chain of processes ending in a final state pion has a step length distribution leading to Lévy-stable distributions. Subsequently, we show that simulated pion freeze-out distributions indeed exhibit heavy tails and can be described by a three-dimensional elliptically contoured symmetric Lévy-stable distribution.…”

Constant modulus algorithm for blind equalization under impulsive noise environments
Published 2009-01-01“…The presence of α stable distributed ambient channel noise in wireless systems can degrade the per-formance of existing constamt modulus(CM) equalizers.The problem of blind equalization in noisy communication channels was investigated by addressing the negative effects of heavy-tailed noise to the original constant modulus algorithm based on a stochastic gradient descent(SGD-CMA).Two modified algorithms were proposed.The first is robust CM algorithm based on SGD(SGD-RCMA) and the second is robust CM based on recursive least square(RLS-RCMA) novel methods are robust under both Gaussian and α stable distributed ambient noise environments.And compared to SGD-RCMA method,the RLS-RCMA method has a significantly faster convergence rate and more powerful ISI impressing ability.…”
