The crossroads between art, science and technology are extended extend into a vast and relatively undefined world, modulated by a series of qualities inherent to their practices in permanent tension: to the revisited frictions between dissimilar disciplines, media and methodologies entailed by these kinds of works, which inevitably make their classification difficult, one adds the frequent labour of artists who tend to incorporate scientific and technical knowhow, or even to work in conjunction with specialists from other fields of discipline, thereby dissolving the dividing lines between the notion of the traditional artwork and the concepts of machine, device, apparatus, artefact and experiment. These attributes not only hinder the categorization of artistic productions, but also challenge the conception of physical and conceptual works, strictly individual or collective, two categories that still dominate the history, theory and aesthetics of contemporary art. This article argues that, in Argentina, this complexity is radicalised by two strands of analysis designated as “identity” and “institutional”. The former is associated with the imaginaries of modernisation that run through the history of Argentinean art, science and technology; the latter refers to the particular logics of growth and expansion of the institutions that have been promoting the confluence of art and technology from the seventies to the present day. In order to show the ways in which both aspects converged in certain initiatives, a 2014 exhibition at the San Martín Cultural Centre, a well-known institution managed by the Government of the City of Buenos Aires, is analysed. After reviewing the imaginings of the future and of innovation that have marked the local circuit, as well as the oscillating institutional developments, the article puts forward possible strategies for exploring imaginaries with a degree of autonomy with respect to the international scene, related to their own research and creation contexts. © 2017, Universitat Oberta de Catalunya.

New teaching approaches like the flipped classroom are an interesting alternative to educate new generations but they represent new challenges for teachers. This paper describes our experience re-designing our classes and study materials in order to adopt a flipped classroom approach combined with some other non-traditional teaching techniques. This experience is focused on the Software Engineering course at Universidad Nacional de Tres de Febrero. In this paper we share details of our strategy, the positive results we obtained and the concerns we still need to address. © 2017 IEEE.

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.

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.

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.

This paper describes a MATLAB program with a graphical user interface (GUI) to calculate the parameters of the autocorrelation and the interaural cross-correlation functions of binaural signal based on the auditory-brain model proposed by Ando [Y. Ando. (1998) Architectural Acoustics: Sound Source, Sound Fields, and Listeners, Springer-Verlag, New York, Chap. 5], which can describe the various subjective attributes such as pitch, timbre, and the spatial impression.

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.

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.

On the basis of the Ando's brain hemispheric specialization auditory model, spatial information is processed in the right hemisphere. When hearing a complex sound stimuli, like a monaural sound source reproduced in a reverberant sound field, several independent acoustic cues are processed in both hemispheres simultaneously. To study the brain specialization perceiving these types of sounds, it was developed the Auditory Evoked Potentials analysis for 2000ms after the first 80ms from the sound onset, even though the first 300ms is normally analyzed, and Cortical Activity descriptors, which were applied to Mismatch Negativity electro-physiological signals taken from Left and Right hemispheres. It was possible to measure the specialization of hemispheres by using two different monaural and anechoic sound sources, one with a minimum effective duration of its autocorrelation function (tau e) as low as 0.2ms and another with minimum tau e of 190ms, both embedded into the same reverberant sound field and reproduced thru headphones. This study opens the possibility to measure the perception of listener envelopment to further develop a subjective descriptor. © 2013 Acoustical Society of America.

The sound fields and the views of several positions in a concert hall and an opera theater were simulated and the subjective preference for different seating positions was investigated. First the seat preference with and without visual stimuli under the conditions of 1) the original sound level (the sound pressure level at each position was maintained as the impulse response measurements in the auditoria) and 2) the equalized sound level were compared since the subjective scale of seat preference showed the highest correlation with sound level in the previous study investigating the opera theater [Sato et al., Acustica united with Acta Acustica, 98 (2012) 749-759]. Some positions were judged acoustically preferred but visually less preferred or vice versa. Thus, another preference test was conducted by using the combinations of the acoustic and the visual stimuli of different positions to further investigate the audio-visual interaction. © 2013 Acoustical Society of America.
