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 ...
Highly Stable Multistage Numerical Methods for Functional Equations: Theory and Implementation Issues
(Universita degli studi di Salerno, 2010-08-06)
Functional equations provide the best and most natural way to describe evolution in time and space, also in presence of memory. In fact, the spread of diseases, the growth of biological populations, the brain dynamics, ...
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 fuzzy logic
(Universita degli studi di Salerno, 2010-05-04)
Si trattano diversi aspetti della logica fuzzy, in particolare: 1) le proprietà preservate da un modello fuzzy ogniqualvolta esso è sottoposto a qualche genere di modifica; 2) la programmazione logica fuzzy, la logica della ...
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 ...
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 ...
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 ...
Uniqueness and partition of energy for thermomicrostretch elastic solids backward intime
(Universita degli studi di Salerno, 2011-06-12)
In questo lavoro, è mostrata l’unicità delle soluzioni per il problema
a ritroso nel tempo della teoria lineare dei materiali elastici termomicrostretch,
ed è provata l’impossibilità della localizzazione nel tempo
della ...
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 ...
