A new technique and an algorithm have been designed which are meant to automatically capture the outlines of fonts. A more flexible class of B! ezier cubic (generalized Hermite cubic) functions are the basis of this technique. This class of functions involves two families of control parameters, to produce more flexible shapes than ordinary Hermite or B!(More)
Based on a new trial function, an analytical coupled technique (a combination of homotopy perturbation method and variational method) is presented to obtain the approximate frequencies and the corresponding periodic solutions of the free vibration of a conservative oscillator having inertia and static non-linearities. In some of the previous articles, the(More)
