Gli usi parlati nei language forum: un modo innovativo per interrogarsi sulla lingua viva

Questo contributo parte da un’analisi delle marche d’uso impiegate nei dizionari per riferirsi alla lingua parlata, prestando particolare attenzione alla marca colloquiale che, essendo quella più neutra rispetto alle altre, non ha una definizione enciclopedica. Il nostro intento è quello di mostrare come gli usi parlati sono segnalati nei dizionari e nei language forum al fine di verificare se gli utenti sono in grado di distinguere i vari registri riconducibili alla lingua parlata e se, in riferimento a determinate unità lessicali, essi fanno ricorso a un’etichetta piuttosto che a un’altra. Attraverso un’analisi esclusivamente lessicale degli usi parlati all’interno dei forum linguistici incentrati sulla lingua inglese è stato possibile verificare quanto e in relazione a quali problematiche gli utenti si mostrano disponibili a iniziare nuove discussioni in rete. Perseguendo il nostro obiettivo abbiamo preso in esame i language forum situati all’interno di due dizionari online, The Free Dictionary e Word Reference, e altri forum e blog creati ad hoc per discutere su che cosa possa considerarsi colloquiale, gergale, informale ecc

Development of an Embedded Myokinetic Prosthetic Hand Controller

The quest for an intuitive and physiologically appropriate human machine interface for the control of dexterous prostheses is far from being completed. In the last decade, much effort has been dedicated to explore innovative control strategies based on the electrical signals generated by the muscles during contraction. In contrast, a novel approach, dubbed myokinetic interface, derives the control signals from the localization of multiple magnetic markers (MMs) directly implanted into the residual muscles of the amputee. Building on this idea, here we present an embedded system based on 32 magnetic field sensors and a real time computation platform. We demonstrate that the platform can simultaneously localize in real-time up to five MMs in an anatomically relevant workspace. The system proved highly linear (R2 = 0.99) and precise (1% repeatability), yet exhibiting short computation times (4 ms) and limited cross talk errors (10% the mean stroke of the magnets). Compared to a previous PC implementation, the system exhibited similar precision and accuracy, while being ~75% faster. These results proved for the first time the viability of using an embedded system for magnet localization. They also suggest that, by using an adequate number of sensors, it is possible to increase the number of simultaneously tracked MMs while introducing delays that are not perceivable by the human operator. This could allow to control more degrees of freedom than those controllable with current technologies

Assessment of non linear bond laws for NSM systems in concrete elements

In this paper the numerical FEM model developed to simulate the behaviour of the NSM strengthening system for concrete elements is presented. The plane model introduces the non linear bond law of the system by an interface element between the composite reinforcement and the concrete considered linear. The results of two experimental programs are analysed and used to calibrate the parameters of the bond shear-slip relationship by means the numerical model. The procedure is based on the inverse analysis of the experimental data in order to have the better fitting of the global pull-out load-displacement curves.(undefined

Assessment of nonlinear bond laws for near-surface-mounted systems in concrete elements

This paper presents a numerical plane Finite Element (FE) Model for use in simulating the behaviour of different types of Near Surface Mounted (NSM) Fibre Reinforced Plastic (FRP) strengthening systems for concrete elements. Based on a nonlinear bond law for simulating the behaviour of the FRP reinforcement-adhesive-concrete interface, the model employs an interface element between the NSM FRP reinforcement and the concrete. The results of two different experimental programs, both dealing with 'bond tests' but with distinct set-ups, are briefly summarised and analysed. The main objective of this research is to assess the values of the parameters that define the nonlinear bond laws for each type of FRP reinforcement tested. This assessment was accomplished by inverse analysis, fitting numerically the pullout load–displacement curves that were experimentally recorded. The effect of bond length on different types of NSM FRP reinforcement is assessed. Finally, the bond behaviour in the transverse plane is examined too.Fundação para a Ciência e a Tecnologia (FCT

Memorie transculturali: estetica contemporanea e critica postcoloniale

[Italiano]:Questo lavoro analizza i differenti modi in cui la memoria transculturale è articolata in alcune pratiche artistiche contemporanee legate a esperienze di migrazione, esilio, diaspora, transnazionalizzazione, e attraverso alcuni esempi di progetti curatoriali e museali innovativi che propongono delle visioni alternative sulle pratiche di memorializzazione e archiviazione del passato, evidenziandone le connessioni con la contemporaneità e la sua configurazione postcoloniale. Nella presente analisi, i distinti ‘casi-studio’, frutto di ricerche indipendenti (maturate nel corso di Dottorato in Studi Culturali e Postcoloniali del mondo Anglofono, all’Università ‘L’Orientale’ di Napoli) e comuni (queste ultime condotte nell’ambito del progetto europeo MeLa*, dedicato al ripensamento dei musei e archivi europei nell’età delle migrazioni globali), sono intrecciati tra loro poiché propongono una riflessione critica sulle complesse e stratificate interconnessioni tra i contesti culturali, geografici, storici, economici e sociali dell’Europa e del mondo contemporaneo, con particolare a attenzione all’area mediterranea, riconoscendo nei processi globali di migrazione e nella loro formazione storica un elemento imprescindibile per la comprensione del presente ./[English]:This volume analyses the several ways in which transcultural memory is articulated in contemporary artistic practices connected to the experiences of migration, exile, diaspora and transnationalization. This task is carried out through examples of innovative curatorial and museum projects, which suggest alternative understandings of practices of memorializing and archiving the past, highlighting its relation with contemporaneity and its postcolonial configuration. In the following analysis, the several ‘case-studies’ are a result of independent and collaborative research (the first was conceived during the PhD course in Cultural and Postcolonial Studies of the Anglophone World, at the University of Naples “L’Orientale”, while the latter was carried out in the context of the European project MeLa*, which deals with the reconsideration of the European museums and archives in the era of global migrations). The two kinds of research are related because they suggest a critical reflection on the complex and stratified interconnections among the cultural, geographic, historic, economic and social contexts of Europe and the contemporary World, paying keen attention to the Mediterranean area and recognizing the global processes of migration and their historic development as essential tools for understanding the present age

Il Matri-Archivio del Mediterraneo: Grafie e Materie

[Italiano]: Il volume Matri-Archivio del Mediterraneo. Greafie e Materie è il risultato di una giornata di studi organizzata in occasione del lancio della piattaforma digitale M.A.M. nel 2015 presso l’Università degli Studi di Napoli “L’Orientale” (http://www.matriarchiviomediterraneo.org). Tra il 2013-2015 l’Unità di ricerca coordinata dalla Prof.ssa Silvana Carotenuto, e costituita da Beatrice Ferrara, Celeste Ianniciello, Annalisa Piccirillo, Manuela Esposito e Roberta Colavecchio (afferenti al Dipartimento di Scienze Umane e Sociali – UNIOR) ha condotto il progetto “L’archivio della performance femminile in area mediterranea. Tentativi digitali (il progetto ha goduto della fonte di finanziamento P.O.R. Campania FSE 2007-2013, Asse IV, Capitale Umano). Sviluppato secondo la prospettiva culturalista e postcoloniale che contraddistingue il gruppo di ricerca, dopo un’approfondita indagine filosofica sulla questione dell’archivio, e in seguito alla formulazione della necessità di intervenire alla creazione di un ‘archivio contemporaneo’, il progetto ha realizzato, in collaborazione con l’azienda software “Intuizioni creative” (Foggia), la piattaforma digitale M.A.M. Il sito web si propone di collezionare, conservare e comunicare le opere contemporanee – ‘Grafie e materie’ (arti visive, fotografia, istallazioni, coreografia, performance, pittura, fumetto, etc.) – realizzate da artiste emergenti nell’area del Mediterraneo. Il volume raccoglie gli interventi di Silvana Carotenuto, Lidia Curti e Giuliana Cacciapuoti, insieme alle interviste condotte dalle ricercatrici con le artiste: Filomena Rusciano, Oni Wong, Alessandra Cianelli, Palù de Andrare and Dacia Manto./[English]: The volume Matriarchive of the Mediterranean.

Between 2013-2015, the research unit coordinated by Professor Silvana Carotenuto, and constituted by Beatrice Ferrara, Celeste Ianniciello, Annalisa Piccirillo, Manuela Esposito and Roberta Colavecchio (based at the Department of Human and Social Science, University of Naples “L’Orientale”) has carried out the project “The Archive of Female Performance in the Mediterranean Area. Digital Attempts” (ruled by the Mobility Procedures within the European Program “Networks of Excellence”, and financed by P.O.R. Campania, Asse IV, Human Capital). The project aims to study the problematic of the ‘archive’ in its theoretical, philosophical, and technological meanings, and in terms of archival praxis from a feminist and postcolonial perspective. The result is the realisation of a digital archive collecting artworks of female artists circulating in the Mediterranean area. This volume collects papers by Silvana Carotenuto, Lidia Curti and Giuliana Cacciapuoti, along with the interviews conducted by the researchers with the female artists: Filomena Rusciano, Oni Wong, Alessandra Cianelli, Palù de Andrare and Dacia Manto

Tracking the dynamics of power sources and sinks during the martensitic transformation of a Cu-Al-Ni single crystal

We have tracked the dynamics of the martensitic transformation in a Cu-Al-Ni single crystal by means of acoustic emission and infrared imaging techniques. A Fourier equation-based post-processing of temperature maps has enabled us to reveal the inhomogeneous and discontinuous character of heat power sources and sinks during the transiton. A good correlation between the dynamics of thermal and mechanical energy release has been evidenced. It has also been shown that the merging of martensitic interfaces results in an enhanced heat absorptio
