Considerações sobre a não-realização da vogal epentética em corpus poético do Português Arcaico

This study has as main aim to discuss the motivation for the non-occurrence of epenthetic vowel at the beginning of the word in the context of word junction in the first hundred Cantigas de Santa Maria (CSM – Afonso X, 1221-1284). Through this work and from a non-explored corpus (especially as for linguistic themes - SNOW, 1987, p. 478-480; MASSINI-CAGLIARI, 2005, p. 24-26), we intended to contribute to reaching a deeper knowledge of Portuguese prosody history in the period of its recognition as an “independent” language in relation to Latin.

A coleta de corpus de aprendizes: questões qualitativas em uma pesquisa sobre a escrita de aprendizes de língua espanhola

In this paper we discuss and present the first results gathered from the compilation of a learner corpus comprised of texts written by university students (Language, Literature and Translation Course). We made use of Corpus Linguistics and observations of researchers from the learner’s corpus field, in order to compile and analyze a corpus of argumentative and descriptive texts written in Spanish. Four hundred compositions were collected (about 120 thousand words) from August 2011 to December 2012. The methodology adopted assisted us considerably in maintaining a comprehensive working agenda, taking into consideration students’ needs and using the data collected as subsidy to improve classroom management of content. We also present the difficulties faced during the data gathering and propose procedures do avoid or minimize them.

Recovery Tests of an Hybrid Current Limiter Composed of a SFCL in Parallel to an Air-Core Power Reactor

The resistive-type superconducting fault current limiters (RSFCL) prototypes using YBCO-coated conductors have shown current limitation for medium voltage class applications for acting time up to 80 ms. By connecting an air-core reactor in parallel with the RSFCL, thus making an hybrid current limiter, one can extend the acting time for up to 1 s. In this work, we report the performance of a hybrid current limiter subjected to an AC peak fault current of 2 kA during 1 s for which within the first 80 ms the SFCL limits the current concurrently with the air-core reactor, and for the remaining 920 ms, only the air-core reactor limits the current. In order to evaluate the actual conditions for subsequent reconnection of RSFCL to the power grid, the hybrid fault current limiter was tested varying the time interval for recovery from 900 ms and 1.2 s, followed again by the concurrent operation of the hybrid limiter during 1 s (SFCL during 80 ms). From this evaluation test, the recovery time can be measured and compared using the voltage peak generated in superconducting module from the first and second fault test. The recovery time was also determined through the pulsed current method (PCM) on short-length sample test. The results showed that the fault current was limited from 1.9 kA down to 514 A after 1 cycle of 60 Hz frequency, with recovery time lower than 1.2 s for two subsequent fault current tests.
