Fluency in interpreting: a native-like quality factor

Lo studio si occupa di fluency e analizza alcuni aspetti che la definiscono (pause vuote, pause piene, segnali discorsivi, riformulazioni). Si analizzano frequenza e durata di tali fenomeni, attraverso due corpora di produzioni orali di due gruppi di parlanti della lingua inglese: gli studenti italiani del corso di Mediazione Linguistica Interculturale della Scuola di Lingue, Letterature, Interpretazione e Traduzione di Forlì, Università di Bologna, e partecipanti britannici di un programma radiofonico. Si è ritenuto utile comparare le produzioni orali di studenti della lingua inglese a quelle di oratori pubblici madrelingua. Si è cercato di bilanciare i due corpora in termini di genere. Sono stati utilzzati i software Praat, per identificare la morfologia e la durata delle variabili, e Notetab Light, per l'annotazione dei corpora. I risultati della ricerca mostrano che le differenze maggiori tra i due gruppi risiedono nella durata delle pause vuote e nella frequenza, durata e e varietà di suoni delle pause piene, oltre a sillabe aggiuntive, sillabe allungate e riformulazioni. Le sillabe aggiuntive appaiono tipiche della produzione orale degli studenti italiani, in quanto, per la maggior parte, le parole della lingua italiana terminano con un suono vocalico. E' inoltre emersa una questione di genere. Le parlanti di sesso femminile, in entrambi i corpora, impiegano maggiormente le variabili della fluency prese in esame, rispetto ai parlanti di sesso maschile. Sulla base di questa ricerca e ricerche future si potranno ideare moduli di insegnamento dell'inglese basati sulla fluency come fattore primario di competenza linguistica. Il Capitolo 1 introduce lo studio. Il Capitolo 2 presenta lo stato dell'arte sul tema. Il Capitolo 3 presenta la metodologia dello studio. Il Capitolo 4 è dedicato a illustrare e discutere i risultati della ricerca. Il Capitolo 5 presenta considerazioni conclusive e future prospettive per l'insegnamento dell'inglese e per la ricerca.

Teledermatology can produce high-quality care at low cost

Teledermatology can provide both accurate and reliable specialist care at a distance. This article reviews current data on the quality of care that teledermatology provides, as well as the societal cost benefits involved in the implementation of the technique. Teledermatology is most suited to patients unable to access specialist. services for geographical or social reasons. Patients are generally satisfied with the overall care that teledermatology provides. Real-time teledermatology is more expensive than conventional care for health services. However, significant savings can be expected from the patient's perspective due to reduced travel. Appropriate patient selection, improved technology and adequate clinical workloads may improve both the quality and cost effectiveness of this service.

Design of high quality doped CeO2 solid electrolytes with nanohetero structure

Doped ceria (CeO2) compounds are fluorite related oxides which show oxide ionic conductivity higher than yttria-stabilized zirconia in oxidizing atmosphere. As a consequence of this, a considerable interest has been shown in application of these materials for low (400-650 degrees C) temperature operation of solid oxide fuel cells (SOFCs). In this paper, our experimental data about the influence of microstructure at the atomic level on electrochemical properties were reviewed in order to develop high quality doped CeO2 electrolytes in fuel cell applications. Using this data in the present paper, our original idea for a design of nanodomain structure in doped CeO2 electrolytes was suggested. The nanosized powders and dense sintered bodies of M doped CeO2 (M:Sm,Gd,La,Y,Yb, and Dy) compounds were fabricated. Also nanostiructural features in these specimens were introduced for conclusion of relationship between electrolytic properties and domain structure in doped CeO2. It is essential that the electrolytic properties in doped CeO2 solid electrolytes reflect in changes of microstructure even down to the atomic scale. Accordingly, a combined approach of nanostructure fabrication, electrical measurement and structure characterization was required to develop superior quality doped CeO2 electrolytes in the fuel cells.

Fabrication of high quality optical coherence tomography (OCT) calibration artefacts using femtosecond inscription

Optical coherence tomography (OCT) is a non-invasive three-dimensional imaging system that is capable of producing high resolution in-vivo images. OCT is approved for use in clinical trials in Japan, USA and Europe. For OCT to be used effectively in a clinical diagnosis, a method of standardisation is required to assess the performance across different systems. This standardisation can be implemented using highly accurate and reproducible artefacts for calibration at both installation and throughout the lifetime of a system. Femtosecond lasers can write highly reproducible and highly localised micro-structured calibration artefacts within a transparent media. We report on the fabrication of high quality OCT calibration artefacts in fused silica using a femtosecond laser. The calibration artefacts were written in fused silica due to its high purity and ability to withstand high energy femtosecond pulses. An Amplitude Systemes s-Pulse Yb:YAG femtosecond laser with an operating wavelength of 1026 nm was used to inscribe three dimensional patterns within the highly optically transmissive substrate. Four unique artefacts have been designed to measure a wide variety of parameters, including the points spread function (PSF), modulation transfer function (MTF), sensitivity, distortion and resolution - key parameters which define the performance of the OCT. The calibration artefacts have been characterised using an optical microscope and tested on a swept source OCT. The results demonstrate that the femtosecond laser inscribed artefacts have the potential of quantitatively and qualitatively validating the performance of any OCT system.

An infrastructure for acquiring high quality semantic metadata

Because metadata that underlies semantic web applications is gathered from distributed and heterogeneous data sources, it is important to ensure its quality (i.e., reduce duplicates, spelling errors, ambiguities). However, current infrastructures that acquire and integrate semantic data have only marginally addressed the issue of metadata quality. In this paper we present our metadata acquisition infrastructure, ASDI, which pays special attention to ensuring that high quality metadata is derived. Central to the architecture of ASDI is a verification engine that relies on several semantic web tools to check the quality of the derived data. We tested our prototype in the context of building a semantic web portal for our lab, KMi. An experimental evaluation comparing the automatically extracted data against manual annotations indicates that the verification engine enhances the quality of the extracted semantic metadata.

A high-power-factor, three-phase isolated AC-DC converter using high-frequency current injection

A single-stage, three-phase AC-to-DC converter topology is proposed for high-frequency power supply applications. The principal features of the circuit include continuous current operation of the three AC input inductors, inherent shaping of the input currents, resulting in high power factor, a transformer isolated output, and only two active devices are required, both soft-switched. Resonant conversion techniques are used, and a high power factor is achieved by injecting high-frequency currents into the three-phase rectifier, producing a high frequency modulation of the rectifier input voltages. The current injection principle is explained and the system operation is confirmed by a combination of simulation and experimental results.
