Combinare insieme piu' mezzi espressivi e' divenuto sempre pi semplice grazie agli sviluppi dell'informatica. I segnali del mondo che ci circonda sono grandezze analogiche, per poter trattare queste grandezze con un elaboratore elettronico e' necessario dapprima convertirle da analogico in...

In this paper a convergence result for the BBGKY hierarchy to a Boltzmann-like equation, in the case of anelastic collision, is shown. Boltzmann-like equations are often used to model dissipative dynamical systems such as granular media. This convergence result aims to make a contribution...

In questo lavoro si considera il problema dello scambio commerciale tra diversi agenti economici utilizzando dei modelli propri della fisica e in particolare della teoria cinetica di un gas rarefatto. La struttura microscopica di un gas è caratterizzata da una miriade di molecole libere di...

In this paper we study a differential game, for resource extraction of a renewable good, in which players are overlapping generations of extractors. The framework of overlapping generation allows us to consider intragenerational (players in the same generation) and intergenerational (players in...

Long Term Fixed Income Market securities present a strong positive correlation in daily returns. By using a metrical approach and considering "modified" time series, I show how it is possible to show a more complex structure which depends strictly on the maturity date.

The Electricity Market (in Europe) undergoes a period of transformations never seen before. The competi-tive model suggested by the European Commission is based on a gradual increase in the classes of consum-ers able to choice, freely, their providers. In general, liberalization, deregulation,...

The Manfredonia City Marine is the third in Italy both for its size and for its nation-wide importance, in the last decade a considerable crisis has been registered in this economic sector as shown by the always decreas-ing number of fishing boats registered in the Harbour-Office. As a result of...

The minority game (MG) comes from the so-called “El Farol bar” problem by W.B. Arthur. The underlying idea is competition for limited resources and it can be applied to different fields such as: stock markets, alternative roads between two locations and in general problems in which the...

In this paper we study a differential game, for the extraction activity of a renewable good, in which players are overlapping generations. The framework of overlapping generations allows us to consider intragenerational (players in the same generation) and intergenerational (players in different...
