It is widely recognized that fuzzy number theory relies on the characteristic function. However, within the fuzzy realm, the characteristic function transforms into a membership function contingent upon the interval [0,1]. This implies that real numbers and intervals represent exceptional cases of fuzzy numbers.

Article Synopsis
  • * Despite their advantages, magnetorheological fluids face challenges like increased friction torque and leakage of carrier liquid when used in rotating seals.
  • * A novel approach involves using extremely bidisperse MR suspensions with micrometer-sized iron particles in a ferrofluid, which not only increases magnetization but also alters flow properties, leading to an innovative sealing mechanism that significantly boosts performance with minimal additives.

Our previous studies of dissociative recombination and vibrational excitation/de-excitation of the BeH ion, based on the multichannel quantum defect theory, are extended to collision energies above the dissociation threshold, taking into account the vibrational continua of the BeH ion and, consequently, its dissociative excitation. We have also significantly increased the number of dissociative states of Π, Σ and Δ symmetry included in our cross section calculations, generating the most excited ones by using appropriate scaling laws. Our results are suitable for modeling the kinetics of BeH in edge fusion plasmas for collision energies up to 12 eV.
