UN METODO NON DISTRUTTIVO PER LA CLASSIFICAZIONE DELLE UOVA DA CONSUMO BASATO SU RETI NEURALI ARTIFICIALI
Le uova da consumo, secondo il regolamento comunitario CE 2295/2003, sono classificate in categorie di freschezza sulla base dell’altezza della camera d’aria, la quale, come noto, aumenta con il tempo di conservazione. Per rispondere a tale esigenza, negli ultimi dieci anni sono stati studiati metodi alternativi alla speratura, poco adatta ad un impiego in linea, quali: spettroscopia o impiego del naso elettronico.
In tale contesto, scopo della presente ricerca è lo studio di una metodologia inedita, in grado di classificare le uova da consumo secondo le categorie di freschezza contemplate dalla normativa, sulla base dell’analisi delle proprietà dielettriche, realizzata attraverso una rete neurale.
La rete neurale è risultata efficace nell’estrarre il contenuto informativo delle misure dielettriche, anche in casi difficilmente affrontabili con i metodi della statistica classica, permettendo di classificare le uova in esame con una precisione superiore al 90%.
I risultati ottenuti mettono in evidenza le potenzialità di sviluppo dell’analisi delle caratteristiche dielettriche unita all’elaborazione statistica con le reti neurali nella classificazione delle uova da consumo, anche nell’ottica di una implementazione in linea del metodo
An ancient pilgrimage route and its changes over time: the “Strada della Cisa”. A proposal for development of cultural heritage and landscape
The International Conference the European Pilgrimage Routes for promoting sustainable and quality tourism in rural areas took place December 4 to 6, 2014 in Firenze (Italy) and was organized by the Department of Agricultural, Food and Forestry Systems – University of Florence in collaboration with the Tuscany Region, the Department for Life Quality Studies and Department of Agricultural Sciences – University of Bologna, the Italian Association of Agricultural Engineering and the European Association of the Francigena Way. The Conference involving 150 experts from 18 countries and was divided into five areas of discussion: conservation and evolution of the landscape along the routes; life quality and social impact; tourism and local development; sustainability in the rural areas; tools and methods for building a tourist attraction
APPLICAZIONE DI RETI NEURALI PER LA CLASSIFICAZIONE DI CULTIVAR DI ALBICOCCO MEDIANTE NASO ELETTRONICO
Nel presente studio è stata valutata la possibilità di classificare dieci cultivar di albicocca interpretando i segnali provenienti da un naso elettronico mediante una rete neurale.
Poichè il raggiungimento di una configurazione stabile richiede un basso impegno computazionale è stato possibile sperimentare diverse configurazioni di rete, con 1, 2 o 3 strati nascosti. La configurazione con un singolo strato nascosto composto da 35 neuroni ha fornito un coefficiente di correlazione superiore all’80% sul test-dataset, e la rete allenata ha permesso la corretta classificazione dei frutti con un’efficacia superiore al 90%, mostrando un potenziale promettente di tali tecniche nel controllo di qualità
Pilgrim Roads: from Medieval Maps to an interactive Application
Some cartographic documents about pilgrims itineraries are examined, in order
to study the abbeys and the hospices where they spent the night and had lunch,
the churches, and the settlements they visited. Many road maps and guidebooks,
in addition to a large variety of documents about this subject, have been existing
since the 13th century: they are critically analyzed to understand their role in the
field of pilgrimage over the different historic periods. Some efforts are focused on
the Iter de Londinio in Terram Sanctam drawn by Matthew Paris from England in
the 13th century and on the map by Erhard Etzlaub, who provided German pilgrims
en route to Rome during the Holy Year 1500 with a detailed map. These
documents were made in different periods, with different instruments (the former
is a manuscript, the latter is a printed map), but they both clearly sketch some
itineraries through Europe, recognizable even nowadays.
The aims of the analysis are two: recognition of old itineraries currently visible
and proposal of an interactive application about a section of the pilgrim itineraries,
mainly for tourists. This is a sort of interactive guide that will show both the
reconstruction of an ancient itinerary and the information about every element
of interest along it (as abbeys, churches, villages, landscape, environment, etc.).
This interactive guide has been inspired by previous applications for tourist itineraries,
particularly walking tours
THE LANDSCAPE OF PILGRIMAGE ROUTES AS TOOL FOR RURAL TOURISM DEVELOPMENT
This study focuses on one of the main pilgrim way in the Friuli Venezia Giulia region (North Est Italy) known as the “Cammino Celeste”. Different landscape types were identified according to an index of soil sealing and indices of land use/land cover calculated in a GIS environment. Then the ECOVAST method of visual analysis was applied for the characterization of different landscape types obtained by Cluster analyis and a final Map of landscapes was achieved. The results highlighted a landscape which changes along the Route: simplified landscape due to intensive agriculture in the south portion of the plain becames rich in natural habitats and built-up areas going up to the hill. From the hills to the mountains, vineyards interspersed with woods give way to the woods and less often to meadows
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
