The role of pause location in perceived fluency and proficiency in L2 Finnish
2022
Fluency is a commonly used descriptor of second language (L2) speaking skills. Unplanned and too frequent pauses, hesitations, and repetitions disrupt the flow of speech and can cause temporal irregularities at all levels of speech hierarchy, from syllable rate to phrasing. However, most studies that attempt to quantify fluency disregard pause locations. The current study investigates, whether and which pause locations affect the perceived fluency and proficiency in L2 Finnish. Several pause parameters were computed from spontaneous L2 Finnish speech samples. Pause locations were investigated with regards to clauses and phrases as well as incomplete words. The effect of pause locations to h…
Desk Set e Reverso: punti di partenza in traduzione automatica
2011
Si propone un raffronto tra strutture a verbo supporto, nel dominio della proposizione, e strutture a determinante nominale complesso, nel dominio del sintagma nominale. Per entrambi i tipi di struttura si avanza l'ipotesi che la testa sintattica non sia quella tradizionalmente riconosciuta e si suggerisce quali siano i punti di partenza ai fini della traduzione automatica.
La dimensione cognitiva nella traduzione assistita da computer e nella traduzione automatica
La tesi sviluppa una riflessione critica sull’utilizzo delle tecnologie per la traduzione, cercando di comprendere come esse siano state sviluppate a partire da rappresentazioni diverse del processo traduttivo umano, e di identificare le ricadute positive e negative che esse producono sul processo di traduzione, sia a livello pratico sia più profondamente, ovvero sulle dinamiche cognitive che lo caratterizzano e sul nuovo modo in cui il traduttore percepisce gli strumenti stessi, il testo e persino il proprio lavoro. The work presents the wide range of translation technologies today available, trying to shed light on the different representations of the human translation process that they t…
Adaptive Control of Underactuated Underwater Vehicles
2008
This paper deals with a control strategy for underactuated underwater vehicles whose target is trajectory tracking. A cascade approach is employed which brings to a control law consisting of: a) an outer loop, obtained from the vehicle kinematic model, which forces this model to track the reference trajectory; b) an inner adaptive control loop which forces the system to track the reference signals given by the outer control loop. Conditions for asymptotic tracking of the trajectory and boundness of the unactuated velocities are given. Simulation tests illustrate the proposed approach.
SLMotion - An extensible sign language oriented video analysis tool
2014
We present a software toolkit called SLMotion which provides a framework for automatic and semiautomatic analysis, feature extraction and annotation of individual sign language videos, and which can easily be adapted to batch processing of entire sign language corpora. The program follows a modular design, and exposes a Numpy-compatible Python application programming interface that makes it easy and convenient to extend its functionality through scripting. The program includes support for exporting the annotations in ELAN format. The program is released as free software, and is available for GNU/Linux and MacOS platforms. peerReviewed
ANALISI DELLE TENSIONI RESIDUE NEL VETRO MEDIANTE LA FOTOELASTICITÀ CON FRANGE DI RIFERIMENTO
2011
L’analisi delle tensioni residue nei vetri viene di solito effettuata con metodi fotoelastici dato che il vetro è un materiale birifrangente. Questa memoria considera l’automazione del cosiddetto "test fringes” metodo che si basa sull’impiego di un compensatore di Babinet o di un provino inflesso. In particolare si propongono due metodi automatici basati sull’impiego del metodo del centro frangia in luce monocromatica e sull’impiego della fotoelasticità RGB in luce bianca. I metodi proposti possono efficacemente sostituire i metodi manuali.
Sensitivity Analysis and Frequency Dynamics of Grid-Connected Converters with Virtual Inertia
2021
For the participation in the frequency control of the system, power converters can be controlled with different strategies and methods, sharing the common concept of virtual inertia capability. In this work, a sensitivity analysis of two main categories of converter controls with virtual inertia is presented. The considered schemes are a grid-following current vector control with additional virtual inertia block and a grid-forming control scheme based on virtual synchronous machine concept. A proper basis for the comparison is first assessed providing an analytical correlation between the control parameters of the two schemes. For the two control strategies, the sensitivity analysis of the …
Evaluation of the wave energy density on the Sicilian coast
2016
In this article the wave energy density of the northern Sicilian coasts is evaluated and is used to evaluate the producibility of a wave nergy converter to be installed in an area in the north west part of Sicily. In particular, the objective of the study is the evaluation of a potential installation in an area between Trapani and Palermo, which are the largest cities in the north west part of Sicily. In particular in this research, the wave energy density of Sicily has been analyzed by using an analysis of wave data carried out in a 10-year period, using the measurements of buoyant of National Wave measuring System (RON - Rete Ondametrica Nazionale). The analysis shows that the north-weste…
Search for Light Dark Matter Interactions Enhanced by the Migdal Effect or Bremsstrahlung in XENON1T.
2019
Direct dark matter detection experiments based on a liquid xenon target are leading the search for dark matter particles with masses above ∼5 GeV/c2, but have limited sensitivity to lighter masses because of the small momentum transfer in dark matter-nucleus elastic scattering. However, there is an irreducible contribution from inelastic processes accompanying the elastic scattering, which leads to the excitation and ionization of the recoiling atom (the Migdal effect) or the emission of a bremsstrahlung photon. In this Letter, we report on a probe of low-mass dark matter with masses down to about 85 MeV/c2 by looking for electronic recoils induced by the Migdal effect and bremsstrahlung us…
Modelling the influence of automaticity of behaviour on physical activity motivation, intention and actual behaviour
2014
In research and in practise social-cognitive models, such as the theory of planned behaviour (TPB), are used to predict physical activity behaviour. These models mainly focus on reflective cognitive processes. As a reflective process, intention is thought to be the most proximal predictor to behaviour. Nevertheless, research suggests that the relation between intention and actual behaviour, the so called intention-behaviour gap, is moderate. Many health-related actions in daily life are performed repetitively and with minimal forethought. In contrast to social-cognitive theories, dual-process theories suggest that behaviour is based on both reflective and automatic processes. Recent researc…
