“…Two sets of simulations were executed to measure the effects of the suggested methodology on the total efficiency of the CPU usage time. The first simulations (DAE) were run using the conventional methodology based on (Hollerbach 1980, Walker and Orin 1982, Korayem and Shafei 2007, Shafei and Mirzaeinejad 2021, in which λ was solved before q¨ followed by the numerical integrations. The second simulations were executed through the methodology based on (2-14), (2-16), (2-19), (2-25), and the recursive algorithm of ODE.…”
