Il design della comunicazione. Metodologie ed esempi di progettazione per la grafica sistematica
No full textCon esempi si esprimono metodologia di progetto per corporate identity e corporate image che sintetizzano alcune complesse
operazioni che concorrono nella maggior parte
dei casi alla costruzione dell’immagine di un ente
e a evidenziarne la sua identità. Tale identità dovrebbe risultare attraverso tutti gli aspetti della
comunicazione visiva, dall’immagine del prodotto
alle varie manifestazioni istituzionali e promozionali
emesse dai diversi media o canali di comunicazione.
Dall’insieme di queste attività deriva,
appunto, la corporate image che dovrà essere
recepita dal pubblico
Le pietre levigate dal mare
No full textGli usi del Rosso Levanto sono soprattutto nel campo dell’arredamento architettonico, nell’oggettistica e in certe decorazioni verticali. Questa
oficalcite è relativamente tenera ed erodibile ma non disdegna anche qualche piccola
scultura. Come Ricercatore presso l’Ateneo fiorentino, io stessa conosco
e ammiro Stefano Alinari: egli è un artista orafo molto quotato nel nostro ambiente
culturale e non solo. Con tratti vibranti ma sicuri, infatti, Alinari mette su
carta la previsione dettagliata della struttura del gioiello, delle forme che lo costituiranno,
dei trattamenti da riservare a ciascun elemento: il metallo levigato o traforato, le pietre
tagliate o cabochon, le superfici riflettenti o scabre e via dicendo, in una meticolosa
prefigurazione del risultato che giunge dunque alla fine non di un occasionale percorso
compiuto spigolando tra trouvailles, ma di una traiettoria riordinata e tenacemente
seguita dalla prima idea compositiva all’oggetto compiuto. Il testo, tra architettura, e design, descrive le mutevoli potenzialità dei marmi delle Cinque Terre
Processi di innovazione del prodotto ceramico. Colore e sistemi di modellazione delle superfici tra artigianalità e tecnologie digitali.
No full textLa ricerca affronta le contemporanee tendenze in atto nel settore ceramico evidenziate da un’innovazione di tipo formale ed emozionale, che deriva dal trattamento delle superfici e all’uso del colore nelle decorazioni. Attraverso i casi studio presentati, il lavoro, da un lato intende dimostrare le possibilità di sviluppo di nuove soluzioni formali e cromatiche per le superfici dell’artefatto ceramico utili a nuovi modelli di personalizzazione del prodotto e nuovi patrimoni emozionali, dall’altro sviluppa con la stampa 3D soluzioni innovative a livello estetico e funzionale di ispirazione bionica sulle superfici dei prodotti ceramici attraverso la modellazione parametrica.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Improvement of a multiphase flow model for wellhead chokes under critical and subcritical conditions using field data
No full textThe characterization of the multiphase flow through valves and orifices is a problem yet to be solved in engineering design, and there is a need for a prediction model able to simulate the complexity of this kind of flow in relation to fluid thermodynamic behaviour, and applicable to different incoming stream conditions and compositions. The present paper describes the development of a global model for the calculation of the discharge coefficient of orifices and choke valves operating under two- and three-phase flow as well as critical and subcritical conditions. The model generalizes the hydrovalve model developed by Selmer-Olsen et al. (in: Wilson (ed) Proceedings of 7th international conference on Multiphase Production, BHR Group, pp 441–446, 1995) and the Henry–Fauske (J Heat Transfer 93: 179–187, 1971. https://doi.org/10.1115/1.3449782) non-equilibrium model on the basis of an updated definition of the discharge coefficient. The model has been adapted to real choke valve geometries, by fitting the discharge coefficient and model parameters using field data from three production wells. The model developed is a global quartic function with different constants for the different valve geometries. The new discharge coefficient allows to simulate field data with high accuracy
Innovating Ceramic Products Through Digitalization and Additive Manufacturing: Two Made in Italy Case Studies
No full textThe research addresses contemporary trends in the ceramic sector in Italy, emphasizing
formal, emotional, and functional innovation through the application of digital
tools in two case studies. The digital transition in the Italian manufacturing sector
involves multiple aspects, such as the automation of production processes, the
adoption of advanced technologies, the digitization of supply chains and the implementation
of artificial intelligence solutions. The adoption of advanced technologies
such as the Internet of Things (IoT), artificial intelligence (AI) and augmented reality
(AR) is also becoming increasingly common in this in the context, enabling real-time
data collection and analysis, process optimization, improved product quality and, in
general, improved efficiency and innovation. Therefore, in both case studies, the goal
is to demonstrate the development possibilities of new formal and chromatic solutions
for ceramic artefacts, facilitating new product customization models, emotional values
and functions
Dissipative bracing and base isolation design solutions for new prefab R/C Structures
No full textA study focused on the application of passive seismic control strategies to the field of new prefab R/C structures is presented herein. A benchmark building was designed to the purpose, assuming the typical geometrical layout and dimensions of single-hall industrial buildings in Italy, which are also similar to the characteristics of the same class of buildings in other countries of the Mediterranean area. The design was carried out in the three following hypotheses: (a) according to a traditional ductility-based approach; (b) by incorporating dissipative bracings, equipped with fluid viscous dampers; (c) by placing a seismic isolation system at the base, composed of a set of double curved surface sliders. The earthquake and performance levels assumed, their relevant limitations, the design criteria and the technical installations of the three solution are discussed in detail. A comparison of relevant sizes, seismic performance and costs is finally presented
Non-linear finite element assessment analysis of a modern heritage structure
No full textA synthesis of a non-linear finite element structural assessment enquiry carried out on a monumental modern heritage building is reported in this paper. The study includes a buckling analysis of the slender steel beams constituting a mushroom-type roof, and an ―integral‖ seismic pushover analysis of the supporting R/C columns. The computational solutions obtained for the steel roof beams are compared to the results derived from a calculation of the critical stress of beam panels, and the global lateral-torsional buckling resistance of members developed according to the Technical Standards adopted for structural verifications. The unconventional ―full-cracking‖ pushover application to the R/C columns offers detailed simulation of the evolution of their non-linear response, which is discussed in the paper, along with the most significant parameter and procedure choices made in the analysis
