Colle Santo Stefano (Ortucchio, AQ)
No full textDurante l’estate 2014 sono ripresi gli scavi del sito di Colle Santo Stefano (AQ), già sottoposto ad indagini tra il 1988 ed il 2006, ad opera di una équipe dell’Università di Pisa, sotto la direzione scientifica di Giovanna Radi (Radi et alii 2001; Radi, Danese 2003; Fabbri et alii 2011; Petrinelli Pannocchia et alii 2016). Le ricerche hanno interessato due aree distinte, poste rispettivamente ad ovest ed a sud-ovest dell’area interessata dai precedenti scavi
Qualitative methods in continuous and discrete dynamical systems
No full textThis chapter gives a general and friendly overview to the qualitative theory of continuous and discrete dynamical systems, as well as some applications to simple dynamic economic models, and is concluded by a section on basic principles and results of optimal control in continuous time, with some simple applications. The chapter aims to introduce some general concepts, notations and a minimal vocabulary concerning the study of the mathematical theory of dynamical systems that are used in the other chapters of the book. In particular, concepts like stability, bifurcations (local and global), basins of attraction, chaotic dynamics, noninvertible maps and critical sets are defined, and their applications are presented in the following sections both in continuous time and discrete time, as well as a brief introduction to optimal control together with some connections to the qualitative theory of dynamical systems and applications in economics
On a discrete-time model with replicator dynamics in renewable resource exploitation
No full textWe consider a discrete-time version of the model proposed by Lamantia and Radi [15] to describe a fishery where a population regulated by a logistic growth function is exploited by a pool of agents that can choose, at each time period, between two different harvesting strategies according to a profit-driven evolutionary selection rule. The resulting discrete dynamical system, represented by a two-dimensional nonlinear map, is characterized by the presence of invariant lines on which the dynamics are governed by one-dimensional restrictions that represent pure, i.e. adopted by all players, strategies. However, interesting dynamics related to interior attractors, where players playing both strategies coexist, are evidenced by analytical as well as numerical methods that reveal local and global bifurcations
Mechanics of Interfacial Cracks between dissimilar Quasicrystals
No full textWe analize the steady propagation of a straight interfacial crack between two dissimilar planar quasicrystals in pure elastic setting and infinitesimal deformation regime. A closed form solution to the balance equations is furnished. Inertia is attributed only to the macroscopic motio
