Analisi e risoluzione del problema dell’allocazione ottima delle risorse
(Universita degli studi di Salerno, 2015-05-14)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 ... -
Stochastic diffusion processes with jumps for cancer growth and neuronal activity models
(Universita degli studi di Salerno, 2015-05-22)In the last decades, great attention has been paid to the description of bio- logical, physical and engineering systems subject to various types of jumps. A jump, or catastrophe, is considered as a random event that ... -
Difficoltà in matematica: percorsi di autoformazione in e-learning
(Universita degli studi di Salerno, 2015-05-06)My PhD thesis enters the sphere of the studies which aims at the integration between the outcomes of the research on mathematical education and the outcomes of the research about e-learning. Particularly, the thesis inquires ... -
Bornological convergences on local proximity spaces and ωµ −metric spaces
(Universita degli studi di Salerno, 2015-05-13)The main topics of this thesis are local proximity spaces jointly with some bornological convergences naturally related to them, and ωµ −metric spaces, in particular those which are Atsuji spaces (or UC spaces), jointly ... -
Ottimizzazione multi-obiettivo: scheduling delle attività di manutenzione delle reti elettriche.
(Universita degli studi di Salerno, 2014-05-16)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 ... -
Analisi, modellazione e previsione della disposizione di uccelli su cavi elettrici
(Universita degli studi di Salerno, 2014-05-15)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 ... -
Old and new problems in continuum structural materials
(Universita degli studi di Salerno, 2014-05-17)The PhD thesis in Mathematics titled "Old and New Problems in continuum structural masterials " is divided into two parts. In Part I ( Chapter I and II relative to the " Old Problems" ) is studied in particular the classic ... -
On the formulation of Einstein general relativity in a phisycal reference system
(Universita degli studi di Salerno, 2012-04-06)The research deals with the breaking of the evolution problem of a reversible material system in two different problems, the initial data problem and the restricted evolution problem. This breaking, intrinsically formulated, ... -
On the solvability of linear PDEs in weighted Sobolev spaces
(Universita degli studi di Salerno, 2012-03-30)In this work we are interested in strong solutions of a Dirichlet problem for an elliptic linear operator... [edited by author] -
Simulation and optimization of crowd dynamics using a multiscale model
(Universita degli studi di Salerno, 2012-04-11)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 ... -
Analysis of a birth and death process with alternating rates and of a telegraph process with underlying random walk
(Universita degli studi di Salerno, 2012-04-24)My thesis for the Doctoral Programme in Mathematics (November 1, 2008 - October 31, 2011) at University of Salerno, Italy, has been oriented to the analysis of two stochastic models, with particular emphasis on the ... -
Numerical treatment of special second order ordinary differential equations: general and exponentially fitted methods
(Universita degli studi di Salerno, 2012-04-19)The aim of this research is the construction and the analysis of new families of numerical methods for the integration of special second order Ordinary Differential Equations (ODEs). The modeling of continuous time ... -
Imbedding and compactness results in some function spaces
(Universita degli studi di Salerno, 2011-03-16)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 ... -
Le potenzialità dell’e-learning nell’apprendimento della matematica
(Universita degli studi di Salerno, 2011-02-18)La tesi indaga e discute le potenzialità dell’e-learning nell’apprendimento della matematica. Oggi la tecnologia dell’informazione e della comunicazione non è più strettamente legata a qualche quadro teorico. In passato ... -
Multi-biclustering solutions for classification and prediction problems
(2011-03-19)The search for similarities in large data sets has a relevant role in many scientific fields. It permits to classify several types of data without an explicit information about them. Unfortunately, the experimental ... -
Multiscale wavelet analysis for integral and differential problems
(Universita degli studi di Salerno, 2011-03-08)The object of the present research is wavelet analysis of integral and differential problems by means of harmonic and circular wavelets. It is shown that circular wavelets constitute a complete basis for L2[0; 1] functions, ... -
Some topics in the theory of generalized fc-groups
(Universita degli studi di Salerno, 2011-02-15)A finiteness condition is a group-theoretical property which is possessed by all finite groups: thus it is a generalization of finiteness. This embraces an immensely wide collection of properties like, for example, ... -
Lukasiewicz logic: algebras and sheaves
(Universita degli studi di Salerno, 2011-02-21)Classical logic arose from the need to study forms and laws of the human reasoning. But soon, it came out the di culties of classical logic to formalize uncertain events and vague concepts, for which it is not possible ... -
Simulation and optimization of supply chains and networks using a macroscopic approach
(Universita degli studi di Salerno, 2011-03-16)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 ... -
