The running autocorrelation function (r-ACF) is obtained by the FFT method based on the Wiener-Khinchine theorem after obtaining the power density spectrum for a signal. This study attempted to reconstruct the original speech signal by using a part of its r-ACF. First the stationary part of the vowel signals were investigated to determine until which delay time of the ACF (maximum time lag) is necessary to recognize the reconstructed signals as the original ones. Then the continuous speech signals were investigated to determine the appropriate integration interval as well as the maximum time lag. © 2013 Acoustical Society of America.

From considerations about the “dematerialisation” of “informational” works developed in Argentina in the nineteen sixties, this paper spans a bridge towards the materiality of contemporary digital arts and digital literature in particular. On this basis, different approaches about how to read that question the idealistic conceptions of literature, which is only conceived as abstract content, are discussed. This paper contends that, in the recovery of the materiality of digital literature, the tradition of concrete poetry —though mostly visual rather than sonorous— and more attentive regards to different “elusive”, yet concrete materialities, such as computer code, among other things are involved. Thus, this paper discusses the prospect of articulation between readings of perceptible and intelligible materialities, which recognizes the confluence of the ways of making sense of the digital culture without neglecting the artistic work with emphasis on the word. Finally, this paper suggest a mode of collaborative reading, articulating and localised that allows for highlighting that the critical ways of reading are not universal, even for a global academic community. © 2015 by FUOC.

A new software reliability model based on the empirical Bayes estimate is developed. The number of failures estimated up to a given time is used in order to estimate the probability of failure appearance during the next time interval. Instead of a non homogeneous in time failure rate as it is usually used to model reliability growth, a failure rate depending non linearly on the previous number of failures is obtained from our model. The estimate is obtained from a mixed Poisson model where the mixing probability density function models the reliability growth. The model can be used either to simulate the cumulative failures curve or to estimate the time between failures. Data of a similar project can be used to estimate the parameters of a given project. Results of simulations and estimated mean time between failures comparing well with experimental data are also shown. © 2015 The Authors. Published by Elsevier B.V.

This article puts forward a sociotechnical analysis of the electronic artwork Proxemia, created by the Argentine artist Mariela Yeregui. In the course of this analysis, aspects of the creative process have been selected which highlight most significantly how this process is not restricted to the artist’s original intention, but rather that it reshapes and expands in line with the agents involved in the various instances on which the piece is shown. To this end, there will be an analysis of the artwork’s progression through two of the galleries and institutions at which it has been installed and exhibited. From that point, it is our intention to highlight the conflicts and solutions that have affected the piece in each of these instances. This will encompass the flexibility that the concept of problem acquires during this process, its sociotechnical construction and the operating definitions constructed by the various agents involved with respect to the work of art. Based on the unique case put forward by Proxemia, the objective of this article is to analyse how, in the production of robotic art, certain factors interfere, intertwine and complexify the process, such as institutionality, variables related to management policies, representations of the artistic scene, the crossover between different knowledge systems and even local considerations. In this respect, we aim to argue that the aforementioned variables interfere with the process not only merely as conditioning factors, or as a framework or context, but rather that, on the contrary, they acquire agency over the final experience of the artwork, influencing the mode in which the piece configures a way of seeing the world. © 2016, Universitat Oberta de Catalunya.

Psychoanalysis and history | Year: 2011
The article analyses the trajectory of Dr. José Bleger (1922-1972), an Argentine psychoanalyst who tried to articulate his triple identity as a Jew, a Marxist, and a psychoanalyst. Bleger played a central role in the constitution of the 'psy movement' and, in more general terms, in the diffusion of a 'psy culture' in Argentina, a country that today is considered as one of the 'world capitals of psychoanalysis'. However, his trajectory showed not only the limits of his projects in the increasingly politically polarized Argentina of the 1960s, as well as their internal contradictions, but also the difficulties of articulating different identities in those agitated times. Through an analysis of Bleger's trajectory this article explores larger issues of Argentine political culture and their relations with the emergence of a psychoanalytic culture.
