A cascade scheme for passivity-based stabilization of a wide class of nonlinear systems is proposed in this paper. Starting from the definitions and basic concepts of passivity-based stabilization via feedback (which are applicable to minimum phase nonlinear systems expressed in their normal forms) a cascade stabilization scheme is proposed for minimum and non-minimum phase nonlinear systems where the constraint of stable zero dynamics imposed by previous stabilization approaches is abandoned. Simulation results of the proposed algorithm are presented to demonstrate its performance.
The study presents F. Suárez’s theory of the principles of sensation in the context of medieval (Averroes, John of Jandun) and renaissance philosophy (Nifo, Cajetan). It proceeds in five steps. First, it considers Suárez’s ontology of sensory cognitive act. Second, it treats Suárez’s theory of the formation of sensible species. Third, it presents Suárez’s ontology of sensible species. Fourth, it exposes Suárez’s theory of the efficient causes of the sensory cognitive act. In conclusion, the author states that Suárez’s theory, compared to the doctrines of Aquinas and Thomists, constitutes the significant historical shift from cognitive passivism to cognitive activism mirroring the Zeitgeist of the Renaissance philosophy without abandoning the basic tenets of the traditional Aristotelian – scholastic philosophy., Studie prezentuje teorii F. Suáreze o principech vnímání v kontextu středověkých (Averroes, John of Jandun) a renesanční filosofie (Nifo, Cajetan). Postupuje v pěti krocích. Za prvé považuje Suárezovu ontologii smyslového kognitivního aktu. Za druhé, jedná se o Suárezovu teorii utváření rozumných druhů. Za třetí, prezentuje Suárezovu ontologii rozumných druhů. Za čtvrté, odhaluje Suárezovu teorii efektivních příčin smyslového kognitivního aktu. V závěru autor uvádí, že Suárez teorie, ve srovnání s učením Tomáše Akvinského a Thomists, představuje významný historický posun od kognitivní passivism na kognitivní aktivismu zrcadlení na Zeitgeist renesančního filozofie aniž bychom opustili základní zásady tradiční aristotelské - scholastické filozofie., and Daniel Heider
In his late philosophy, Levinas finds that the human being, along with his body, is constituted by “sensibility as proximity, as signification, as one-for-the-other, which signifies in giving”; otherwise he or she is not human. For Levinas, therefore, it is also an affectivity, which, in its bind to the Other, opens up as a sensitivity to the Other. The Other is what animates affectivity. In Otherwise than Being or Beyond Essence, “the passage to the physico-chemico-physiological meanings of the body”, that is prepared by “sensibility as proximity, as signification, as one-for-the-other”, as the materialization of the body, is now exclusively reabsorbed in ethical signification. Nevertheless, the article shows some other figures of incarnation in the earlier works of Levinas as well: the position and the enjoyment.
