Autor: D. Baleanu, M. Hassan Abadi, A. Jajarmi, K. Zarghami Vahid, J.J. Nieto

Publikováno v: Alexandria Engineering Journal, Vol 61, Iss 6, Pp 4779-4791 (2022)

A generalized version of fractional models is introduced for the COVID-19 pandemic, including the effects of isolation and quarantine. First, the general structure of fractional derivatives and integrals is discussed; then the generalized fractional

A new and general fractional Lagrangian approach: A capacitor microphone case study

Autor: A. Jajarmi, D. Baleanu, K. Zarghami Vahid, H. Mohammadi Pirouz, J.H. Asad

Publikováno v: Results in Physics, Vol 31, Iss , Pp 104950- (2021)

In this study, a new and general fractional formulation is presented to investigate the complex behaviors of a capacitor microphone dynamical system. Initially, for both displacement and electrical charge, the classical Euler–Lagrange equations are
