La filosofia del suono in Martin Heidegger

Is it possible to draw up a philosophy of sound in Heidegger? And is a phenomenology of the world as given through sound possible? Among post-Husserlian philosophers, Heidegger most radically emphasizes the inseparability of subject and world, to the extent that he avoids using such terminology to describe this kind of synusia. However, in the Heideggerian opus this fundamental determination is indicated both narrowly and loosely. The human being (das menschliche Seiende) can inquire into its...

Some peculiar families of correlation functions

In this paper a generalization of some families of correlation functions has been proposed; in particular, a generalization of the rational correlation family, as well as a generalization of a subclass of Matérn family have given, together with some relevant properties involving the two classes. Moreover, an extension of the subclass of Matérn family for the two-dimensional and three-dimensional Euclidean spaces has been provided; in addition, the importance of the proposed models for analysi...

Further advances on isotropic correlation models with negative values

Most of the covariance models utilized in spatial and in spatio-temporal data analysis are non negative; at this purpose, covariance functions characterized by negative values need to be explored not only to analyze some particular case studies characterized by negative correlation, but also and most importantly to provide richer families of correlation models. In this paper new families of correlation functions will be proposed, among the others, a generalization of the Cauchy correlation fa...
