Language learning tasks ans automatic analysis of learner language : connecting FLTL and NPL in the design of ICALL materials supporting effective use in real-life instruction
Esta investigación se encuentra en la encrucijada entre el Procesamiento del Lenguaje Natural y el Aprendizaje y Enseñanza de Lenguas Extranjeras y, en concreto, dentro del área denominada Aprendizaje de Lenguas Asistido ...
Language learning through extensive TV viewing. A study with adolescent EFL learners
This doctoral dissertation explores the benefits of an extensive exposure to L2 television for content comprehension and vocabulary learning with beginner, adolescent EFL learners, through a longitudinal classroom-based ...
Language learning with correction queries
In the field of grammatical inference, the goal of any learning algorithm is to identify a target concept from a given class by having access to a specific type of information. The main learning settings are Gold's model ...
Language policy and internationalisation: The experience of international students at a Catalan university
La internacionalització la universitat ha generat un increment de la comunicació intercultural entre els estudiants i el personal acadèmic i administratiu. En universitats públiques com la Universitat de Lleida (UdL), ...
Language transfer in second language acquisition. Some effects of L1 instruction (Romanian) on L2/L3 learning (Catalan/Spanish)
In migration contexts, the diversity of languages in contact triggers the processes of second language (L2) acquisition and language transfer; as well as drawing attention to the importance of mother tongue (L1) maintenance. The ...
Language: universals, principles and origins
Here, old and new linguistic universals, i.e. properties obeyed by all languages on Earth are investigated. Basic principles of language predicting linguistic universals are also investigated. More precisely, two principles ...
Languages Generated by Iterated Idempotencies.
The rewrite relation with parameters m and n and with the possible length limit = k or :::; k we denote by w~, =kW~· or ::;kw~ respectively. The idempotency languages generated from a starting word w by the respective ...
Lanthanide-based dielectric nanoparticles for upconversion luminescence
En esta tesis se ha estudia la luminiscencia y la emisión anti-stokes visible por excitación infrarroja a 980 nm, en iones lantánidos embebidos en nanoestructuras de Lu2O3 y KLu(WO4)2, en los cuales los iones lantánidos ...
Large cardinals and resurrection axioms
In the current dissertation we work in set theory and we study both various large cardinal hierarchies and issues related to forcing axioms and generic absoluteness. The necessary preliminaries may be found, as it should ...
Large scale analysis of communication cues in negotiation
Què fa que algunes persones siguin millors negociadors que altres? En aquesta tesi, faig servir programari de reconeixement d'expressió facial, processament de llenguatge natural i eines estadístiques recents (com la tècnica ...
Large scale battery systems in distribution grids
The increasing integration of renewable energy installations at the distribution grid level has led to a strong increase in grid reinforcement measures in recent years. Since the costs are being passed on to the general ...
Large Scale Excitations in Disordered Systems
Disorder is present in many systems in nature and in many different versions. For instance, the dislocations of a crystal lattice, or the randomness of the interaction between magnetic moments. One of the most studied ...
Large scale finite element solvers for the large eddy simulation of incompressible turbulent flows
In this thesis we have developed a path towards large scale Finite Element simulations of turbulent incompressible flows. We have assessed the performance of residual-based variational multiscale (VMS) methods for the ...
Large scale geostatistics with locally varying anisotropy
Classical geostatistical methods are based on the hypothesis of stationarity, which allows to apply repetitive sampling in different locations of the spatial domain, in order to obtain enough information to infer cumulative ...
Large scale image retrieval base on user generated content
Los sistemas online para compartir fotos proporcionan una valiosa fuente de contenidos generado por el usuario (UGC). La mayor a de los sistemas de re- cuperaci on de im agenes Web utilizan las anotaciones textuales ...
Large scale photovoltaic power plants: configuration, integration and control
This thesis focuses on the operation and control of Large Scale Photovoltaic Power Plants (LS-PVPPs) according to grid code requirements with a special focus on the basic unit: the PV generator. The aim of this thesis is ...
Large scale quantitative assessment of biodiversity using next-generation sequencing
Actualment, els mètodes moleculars són aplicats àmpliament en l’estudi de comunitats biològiques. Pels organismes eucariotes, la tècnica dominant és el DNA metabarcoding. Aquest tècnica es basa en l’amplificació amb PCR ...
Large scale structure and dark energy
The cosmic expansion history tests the dynamics of the global evolution of the universe<br/>and its energy density contents, while the cosmic growth history tests the evolution of the<br/>inhomogeneous part of the energy ...
Large scale structure with Lyman-alpha absorption surveys
[cat] Gran part dels estudis presentats en aquesta tesi doctoral estan vinculats als esforços per detectar les oscil·lacions acústiques dels barions (BAO, de l’anglès Baryon Acoustic Oscillations) en la funció de correlació ...
Large vocabulary continuous speech recognition for the transcription of Catalan broadcast news and conversations : towards analysis and modelling of acoustic reduction in spontaneous speech
The transcription of spontaneous speech still poses a challenge to state-of-the-art methods for automatic speech recognition. The present thesis describes the comprehensive development of a large vocabulary continuous ...
