Analisi filogenetica condotta su ceppi di Bovine Diarrhea Virus (BVDV) isolati in Sicilia
2011
La Diarrea Virale del Bovino-Malattia delle Mucose, è una malattia infettiva che colpisce i bovini, ampiamente diffusa a livello mondiale. L’agente infettivo responsabile è un virus provvisto di envelope e con un genoma ad RNA a singolo filamento e a polarità positiva, appartenente al genere Pestivirus, famiglia Flaviviridae. A causa dell’elevata capacità di andare in contro a mutazioni genetiche, esistono numerose varianti di BVDV con diverso assetto antigenico e differente patogenicità. Ad oggi sono noti due genotipi: il BVDV-I e il BVDV-II. Il BVDV-I comprende almeno 13 sottotipi, mentre ne sono stati descritti solo 2 per il BVDV-II. Quest’ultimo, poco diffuso nel nostro territorio, è re…
Solution of an initial-value problem for parabolic equations via monotone operator methods
2014
We study a general initial-value problem for parabolic equations in Banach spaces, by using a monotone operator method. We provide sufficient conditions for the existence of solution to such problem.

The Krasnosel'skii fixed-point theorem is a powerful tool in dealing with various types of integro-differential equations. The initial motivation of this theorem is the fact that the inversion of a perturbed differential operator may yield the sum of a continuous compact mapping and a contraction mapping. Following and improving this idea, many fixed-point results were proved.\\ The authors present significant and interesting contributions in this direction. In particular, they give the following main theorem: \begin{theorem} Let $M$ be a nonempty bounded closed convex subset of a Banach space $E$, $S:M \to E$ and $T:M \to E$. Suppose that \begin{itemize} \item[(a)] $S$ is 1-set-contractive…

Medical news aggregation and ranking of taking into account the user needs
2019
The purpose of this work is to develop an intelligent information system that is designed for aggregation and ranking of news taking into account the needs of the user. The online market for mass media and the needs of readers, the purpose of their searches and moments is not enough to find the news is analyzed. A conceptual model of the information aggression system and ranking of news that would enable presentation of the work of the future intellectual information system, to show its structure is constructed. The methods and means for implementation of the intellectual information system are selected. An online resource for aggregation and ranking of news, news feeds and flexible setting…
GEOMETRIC AND RADIOMETRIC ANALYSIS OF PAINTINGS
2010
The paper reports an overview of some experiences carried out by some Italian research groups (Politecnico di Milano, University of Palermo, Bruno Kessler Foundation in Trento) aimed to assess the conservation‟s state of some analysed paintings and provide useful information for further diagnostic applications. The activities were accomplished in interdisciplinary teams composed of photogrammetrists, surveyors, restorers and experts of non-destructive diagnostic techniques for Cultural Heritage. Two main aspects are considered: (i) the analysis of the radiometric contents using multispectral images and (ii) the 3D surveying for geometric deformation analysis by means of photogrammetry and l…

On the representations in GF(3)^4 of the Hadamard design H_11
2020
In this paper we study the representations of the 2-(11,5,2) Hadamard design H_11 = (P,B) as a set of eleven points in the 4-dimensional vector space GF(3)^4, under the conditions that the five points in each block sum up to zero, and dim ‹P› = 4. We show that, up to linear automorphism, there exist precisely two distinct, linearly nonisomorphic representations, and, in either case, we characterize the family S of all the 5-subsets of P whose elements sum up to zero. In both cases, S properly contains the family of blocks B, thereby showing that a previous result on the representations of H_11 in GF(3)^5 cannot be improved.
