Quantum harmonic oscillator algebras as non-relativistic limits of   multiparametric $gl(2)$ quantizations
  Multiparametric quantum $gl(2)$ algebras are presented according to a classification based on their corresponding Lie bialgebra structures. From them, the non-relativistic limit leading to quantum harmonic oscillator algebras is implemented in the form of generalized Lie bialgebra contractions.
