This paper shows an example of strong rank reversal in group decision making. Decision makers have preferences expressed through a reciprocal paired comparison matrix. Every one of them applies the eigenvector priority function to her paired comparison matrix to obtain her individual priority vector and then a group priority vector is computed by any of the following two procedures: a) Averaging the already computed individual priority vectors, and b) Averaging the entries of the comparison matrices to obtain a group comparison matrix, and applying to it the eigenvector priority function. Strong rank reversal means that there is one alternative that has the highest priority for every decision maker, and consequently the highest priority in the averaged priority vector obtained by procedure (a), but loses such highest priority when procedure (b) is applied.

This paper deals with autonomous vehicles. This could be considered a utopian goal nowadays but recent advances bring it closer than ever. Automation of the actuators involved in the management of a car, and control of the steering wheel constitute two of the most complex issues involved. We here describe an automatic power steering architecture to manage the steering wheel via an Ethernet controller. An on-board PC is connected to the controller to permit handling by computer generated signals. An electric car has been equipped with the system, and we present the results of tests of the behaviour of the system in real situations on the private driving circuit at the IAI facilities.

Artykuł dotyczy pojazdów autonomicznych. Ich budowa mogłaby zostać uznana jako cel utopijny, jeśli by nie najnowsze osiągnięcia techniki. Najbardziej skomplikowana jest w tym przypadku automatyzacja siłowników umożliwiających kierowanie samochodem oraz regulację kierownicy. W niniejszej pracy opisano architekturę systemu automatycznego wspomagania kierownicy poprzez sterownik Ethernet obsługujący sygnały generowane przez komputer pokładowy. Przedstawiono wyniki badań eksperymentalnych zachowania się opracowanego systemu, stanowiącego wyposażenie samochodu elektrycznego i testowanego w warunkach rzeczywistych na torze jazdy wydzielonym w IAI.

Important environmental and radiological applications require energy deposition models including the interactions between the secondary electrons and the atoms or molecules of the medium. In this work we propose a method to obtain reliable cross-section data to be used in these models by combining total and ionisation cross-section measurements with simple calculations of the differential and integral elastic cross sections. The energy loss spectra obtained in this experiment have been also used to derive the stopping power of the considered materials for electrons. Some examples of results for atomic (Xe) and molecular (CF4) targets are presented and discussed in this paper.
