Abstract
One of the most important terms in Jungian psychology is "collective unconscious". The contents of the collective unconscious form "archetypes", which Jung considers the psychological forms of the old, inherent and inherited remains of the human mind and outside the circle of events in people's lives. Traces of archetypes can be found in the world's valuable literary works, and the comparative study of works from this perspective is considered as one of the important studies of literary research. The aim of the present research is to investigate the archetypes in two important literary works, Dante's Divine Comedy and the story of Ibn Sina's Hayy bin Yaqzan, in order to find out the commonalities and differences of these two works in the archetypes section, and realize the possible reasons for that. The method used in this research was text analysis. The results show that the archetypes of "travel", "shadow", "sage" and "self" can be seen in both works, and the archetypes of "rebirth" and "passing the water" are the cases of differences.

Abstract
Parallel robots have a lot of compared to their counterparts, serial robots, such as higher accuracy, more load to weight ratio, and higher stiffness, which contribute to their various, and precise applications. Stiffness of the robot, as one of the most crucial parameters which should be considered in of the robot, the desired application. In this paper, an experimental study is investigated on evaluation of the robot’s stiffness and the errors corresponding to of the mechanism, which indicate the displacement of -effector of the robot with respect to external imposed forces. The aim of this paper is to evaluate the stiffness and the errors due to the softness behavior of the mechanism of a 3 degree of freedom (3-DoF) parallel robot; for this end, the amount of transfer of the final executor to the applied load is simulated. First, the 3-DoF decoupled robot is introduced and its features are expressed and the stiffness of the mechanism is modeled using Finite Element Method (FEM). Then, of the mechanism is determined in different positions of the end-effector by considering predefined boundary conditions. In order to evaluate the obtained model of the robots’ stiffness, a novel experimental setup is developed to measure the stiffness of the mechanism. By employing the setup, of the robot is measured in different conditions. Finally, the output results of the stiffness model are compared to the experimental tests. The results reveal that the 3-DoF decoupled parallel robot shows a proper stiffness behavior. Hence, it can be employed in various applications with high precision.
