The paper presents a model of an articulated vehicle with a flexible frame of a semi-trailer. The rigid finite element method in a modified formulation is used for discretisation of the frame. In order to carry out effective numerical simulation, a reduced model with a considerably smaller number of degrees of freedom is proposed. The parameters of the reduced model are chosen in an optimization process by using a genetic algorithm. To this end, it is assumed that the full and reduced model have to be similar in the range of static deflections and frequencies of free vibrations. Numerical simulations are concerned with the influence of the flexibility of the frame on the motion of the articulated vehicle during an overtaking maneuver. Results are presented and discussed.

This article explores the significance of James Hillman's archetypal psychology for the autothematic reflection and the fiction of Olga Tokarczuk. An analysis of her 2020 collection of essays Czuły narrator ( The Tender Narrator), and the psychological dimension of two novels, Ostatnie historie ( Final Stories) and Bieguni ( Flights) published in 2004 and 2007 respectively, shows that she abandoned her former intellectual master Carl Gustav Jung for Jungian revisionists, most notably James Hillman. His ideas helped her to clarify her own philosophical approach, and, for her critics, they offer a useful interpretative key to the works in which she moved beyond the bounds of orthodox Jungianism.
