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 financial and innovation literature generally claims that venture capital (VC) investments spur the growth of new technology-based firms (NTBFs). However, it has proved difficult so far to separate the "treatment" effect of the VC investment from the "selection" effect attributable to the...
