A serious error exists in the above paper. The equation (7) in [1] is as follows d2y(t) dt2 + ?? dy(t) dt + ??y(t) = x(t) (1) where the functions x(t) and y(t) are the input and output signals. From figure 2 in [1] it is seen that the units of parameter ?? are meters(length). From figure 3 in [1] it is seen that the units of parameter ?? are also meters(length). From figure 4 in [1] it is seen that the units of parameter t are second(time). Thus the units of the terms in Eq. (1) are as follows d2y(t) dt2 : y(t)sec???2 ?? dy(t) dt : y(t)msec??? 1 ??y(t) : y(t)m In a Physics equation all terms must have the same units. For that reason the Eq. (1) is wrong. The entire work in [1] is based on Eq. (1). Taking into account that Eq. (1) is the basic equation in [1] it is obvious that all subsequent results are wrong. Superscript/Subscript Available</comment
