    L1 attrition in Spanish speakers of English: split intransitivity and the syntax−semantics interface

    Get PDF
    Research on bilingual linguistic development has demonstrated that, after prolonged use of a second language (L2), syntactic structures from the first language (L1) that interface with extralinguistc factors (i.e. syntax−discourse interface) may be vulnerable to attrition. This dissertation presents data from an experimental study intended to test whether syntactic structures that interface with other linguistic aspects (i.e. syntax−semantics interface) are also affected by attrition. Split intransitivity, an understudied phenomenon in L1 attrition, was chosen to evaluate this possibility. An experimental group of Spanish speakers who presented conditions conductive to L1 attrition, as well as a control group of non-attrited Spanish speakers, performed an Acceptability Judgment Task. The results revealed no significant differences between the two groups, suggesting that language structures dependent on syntax−semantics interface conditions have greater stability and are, therefore, unaffected in L1 attrition.La investigación sobre el desarrollo lingüístico bilingüe ha demostrado que, tras el uso prolongado de una segunda lengua (L2), las estructuras sintácticas de la primera lengua (L1) que interactúan con factores extralingüísticos (i.e. interfaz sintáctico-discursiva) pueden resultar vulnerables a atrición. Este trabajo presenta datos de un estudio experimental destinado a comprobar si las estructuras sintácticas que interactúan con otros aspectos lingüísticos (i.e. interfaz sintáctico-semántica) también experimentan efectos de atrición. El fenómeno de intransitividad escindida, poco estudiado en atrición de la L1, fue escogido para evaluar dicha posibilidad. Un grupo experimental de hablantes españoles en condiciones que conducen a la atrición, así como un grupo control de hablantes españoles sin atrición, realizaron una prueba de juicios de aceptabilidad. Los resultados no revelaron ninguna diferencia significativa entre los dos grupos, lo que sugiere que las estructuras lingüísticas en la interfaz sintáctico-semántica son más estables y no se ven, por tanto, afectadas por la atrición de la L1.Departamento de Filología InglesaGrado en Estudios Inglese

    Integration of DERs on power systems: challenges and opportunities

    Get PDF
    The integration of large amounts of distributed energy resources (DERs) as photovoltaic solar generation, micro-cogeneration, electric vehicles, distributed storage or demand response pose new challenges and opportunities on the power sector. In this paper, we review the current trends on: i) how consumers adopting DERs can self-provide energy services and provide other services at system level, ii) what can be expected at distribution networks and how retail markets will evolve with more proactive and market engaged consumers, iii) what are the effects and integration of DERs on wholesale markets, and iv) what are the challenges that DERs pose on cybersecurity and the opportunities for improving system resilience. Several recommendations are given for achieving an efficient integration of DERs. For instance, the design of a comprehensive system of prices and charges and the elimination of existing barriers for market participation are crucial reforms to achieve a level playing field between distributed and centralized resources when providing electricity services. This paper summarizes part of the work developed under the MIT Utility of the Future study

    Shack - Hartmann spot dislocation map determination using an optical flow method

    Get PDF
    We present a robust, dense, and accurate Shack-Hartmann spot dislocation map determination method based on a regularized optical flow algorithm that does not require obtaining the spot centroids. The method is capable to measure in presence of strong noise, background illumination and spot modulating signals, which are typical limiting factors of traditional centroid detection algorithms. Moreover, the proposed approach is able to face cases where some of the reference beam spots have not a corresponding one in the distorted Hartmann diagram, and it can expand the dynamic range of the Shack-Hartmann sensor unwrapping the obtained dense dislocation maps. We have tested the algorithm with both simulations and experimental data obtaining satisfactory results. A complete MATLAB package that can reproduce all the results can be downloaded from [http://goo.gl/XbZVOr]

    Nanotechnology for high frequency communications: nitrides and graphene

    Get PDF
    The achievement of higher frequencies (HF) and the reduction of energy consumption, to improve sensing, communication and computation, involve the continued scaling down to the nanometer level. This scaling is enabled by of innovative device designs, improved processing technologies and assessment tools, and new material structures. In this work, we have used all these factors to demonstrate state-of-the-art HF devices in two materials with quite different electronic properties: wide semiconductor bandgap III-nitrides for resonators and power amplifiers; and graphene, a zero bandgap material expected to revolutionize low noise and HF flexible electronics. Some issues faced during their development will be discussed during the talk
