La construcción de las dos últimas novelas de Javier Cercas: soldados de salamina y la velocidad de la luz

Con la novela Soldados de Salamina obtuvo Javier Cercas uno de los mayores éxitos editoriales de los últimos años. Este artículo trata de desvelar, desde dentro, las claves que ha manejado el autor para escribir una novela que ha merecido el reconocimiento unánime de críticos y lectores. Así como la reincidencia en este modelo narrativo en su última novela publicada: La velocidad de la luz

A Note on the Predictive Content of PPI over CPI Inflation: The Case of Mexico

This note studies the causal relationship that may exist between the producer price index (PPI) and the consumer price index (CPI). In contrast with previous international studies, the results suggest that, in the case of Mexico, information on the PPI seems to be useful to improve forecasts of CPI inflation. In particular, CPI inflation responds significantly to disequilibrium errors with respect to the long-run relationship between consumer and producer prices. These results are based on in-sample and out-of-sample tests of Granger causality, in the context of an error correction model.Cointegration, forecast evaluation, Granger causality, vector error correction.

An Efficient Pipeline Wavefront Phase Recovery for the CAFADIS Camera for Extremely Large Telescopes

In this paper we show a fast, specialized hardware implementation of the wavefront phase recovery algorithm using the CAFADIS camera. The CAFADIS camera is a new plenoptic sensor patented by the Universidad de La Laguna (Canary Islands, Spain): international patent PCT/ES2007/000046 (WIPO publication number WO/2007/082975). It can simultaneously measure the wavefront phase and the distance to the light source in a real-time process. The pipeline algorithm is implemented using Field Programmable Gate Arrays (FPGA). These devices present architecture capable of handling the sensor output stream using a massively parallel approach and they are efficient enough to resolve several Adaptive Optics (AO) problems in Extremely Large Telescopes (ELTs) in terms of processing time requirements. The FPGA implementation of the wavefront phase recovery algorithm using the CAFADIS camera is based on the very fast computation of two dimensional fast Fourier Transforms (FFTs). Thus we have carried out a comparison between our very novel FPGA 2D-FFTa and other implementations

Architecture after Duchamp

[Extract] the end of art - I had my first contact with Hegel through a text by an art theorist whom I am very fond of: John Roberts. The article is titled “Conceptual Art and Imageless Truth”1 and begins precisely with an approach to Hegel’s concept of “the end of art”. The text is about conceptual art. It is structured by relating the work of different conceptual artists with a common denominator that Roberts identifies with Hegel’s notion of “imageless truth”...info:eu-repo/semantics/publishedVersio
