In this work of thesis, the Riemann zeta function was studied by using an unconventional approach. The reason for choosing this approach was to explore the many applications that the Riemann zeta has not only in pure ...

The service sector lies at the heart of industrialized nations and continues to serve as a major contributor to the world economy. Over the years, the service industry has given rise to an enor- mous amount of technological, ...

A conservation law is a partial di_erential equation, in which the variable is a quantity which remains constant in time, that is it cannot be created and destroyed. Thanks to the conservation laws it is possible to de_ne ...

In this thesis, a mathematical model to optimize the allocation of human resources is presented. The problem can be summarized as follows: given a set of jobs (or tasks), tath must be performed by a set of resources in ...

In the last decades, the modeling of crowd motion and pedestrian .ow has attracted the attention of applied mathematicians, because of an increasing num- ber of applications, in engineering and social sciences, dealing ...

The aim of thesis is to present some macroscopic models for supply chains and networks able to reproduce the goods dynamics, successively to show, via simulations, some phenomena appearing in planning and managing such ...

Abstract Nello studio di vari problemi ellittici con soluzioni in spazi di Sobolev S( ) (con o senza peso) definiti su un aperto di Rn, non necessariamente limitato o regolare, spesso risulta necessario stabilire ...

The problem addressed is "the spontaneous arrangement of birds on a wire horizontally." We evaluated several models and, starting from biological and ethological basis, we defined a new one then checked for consistency ...

In questo lavoro di tesi è stato introdotto un modello matematico per ottimizzare l’assegnazione dinamica di lavori di manutenzione delle reti elettriche. Il problema può essere così sintetizzato: dato un insieme di ...

Aim of this manuscript is to give generation results and some Hardy inequalities concerning elliptic operators with unbounded coefficients of the form Au = div(aDu) + F ·Du + V u where V is a real valued function, a(x) = ...
