In this paper, finding Dynamic Load Carrying Capacity (DLCC) of flexible link manipulators in point to-point motion was formulated as an optimal control problem. The finite element method was employed for modelling and deriving the dynamic equations of the system. The study employed indirect solution of optimal control for system motion planning. Due to offline nature of the method, many diffic...

A new optimality principle for the branching angles of blood vessels in the cardiovascular system is proposed: the principle of minimum drag. The results are examined in the light of general observations and compared with those obtained from the principles of minimum work and minimum volume. It is shown that in some aspects the new principle is equally consistent with observations, and, in othe...

The unification of the basic physical laws, from classical physics, quantum physics to gravitic physics seems now possible. The key for this unity is the principle of eurhythmy, literally from the Greek, the principle of the most adequate path. It will be shown that Heron principle of minimum path, Fermat ́s principle of minimum time and de Broglie ́s guiding principle are no more than mere parti...
