Los objetos en los escenarios de la memoria: aproximaciones teóricas y análisis de ejemplos referidos a los hijos de desaparecidos en Argentina
2020
Proponemos, en primer lugar, reflexionar en torno a tres tipos de objetos vinculados a diversos escenarios de la memoria: el objeto testimonio que funciona como un código verificativo cuya primera intención consiste en certificar el acontecimiento; el objeto memoria que despliega un trabajo con la memoria de tipo reflexivo-interpretativo y/o elaborativo, y el objeto emblema que se presenta y actúa en las marchas, en las conmemoraciones, en los juicios, en las protestas y demandas articuladas en las luchas por la memoria, verdad y justicia. Focalizamos luego en el examen de un conjunto de producciones culturales realizadas por los hijos de víctimas del terrorismo de Estado desplegado en torn…

Appropriation and restitution in the Argentinian Dictatorship's Children of the Disappeared Narratives: The missing alive
2020
Junto con el secuestro y desaparición de personas, el terrorismo de Estado en Argentina –que operó en su mayor parte durante la dictadura (1976-1983)– puso en práctica un plan sistemático para la apropiación de sus hijos, ya sea aquellos niños de poca edad que estaban con sus padres en el momento del allanamiento de la casa o los que nacían en centros clandestinos de detención, producto del secuestro de mujeres embarazadas, a las que se solía cuidar hasta dar a luz para luego ser asesinadas. Se trata de los “niños apropiados” o los “desaparecidos vivos” que las Abuelas de Plaza de Mayo procuran encontrar para devolverles su identidad primera. En este artículo exploramos, a partir de un ampl…
Perpetrators fathers: Perspectives from the sons and daughters of Argentinian repressors
2020
En el presente artículo propongo abordar la figura del perpetrador elaborada desde la mirada de los hijos e hijas de represores en Argentina, es decir la representación del “padre perpetrador”. Esta perspectiva viene a agregar un nuevo capítulo a la tradición sobre el represor que ahora es revisitada por sus propios hijos, en especial aquellos hijos/as desobedientes que reniegan y se distancian de sus padres. Nos interesa señalar la reciente creación en 2017 del colectivo Historias Desobedientes: Familiares de genocidas por la Memoria, la Verdad y la Justicia ya que constituye una nueva voz con sus peculiares aportes y demandas en las políticas y prácticas de la memoria. Si bien partimos de…
Piccole città per quarantenni. Sul senso di sé nella scrittura storiografica, in margine a un libro di Vanessa Roghi
2019
Starting from an analysis of Vanessa Roghi's recent book, Piccole città, we focus on the link between historiographic writing and autobiography. In particular, it analyzes the way this link changed at the end of the twentieth century, when political categories that had determined identities, even of historians, for more than a century, have finished. Since then, issues considered "private" have emerged in the public debate and in the historiographic debate, as happened for example with drug addiction, at the centre of Roghi's book.
Robots that look like humans: A brief look into humanoid robotics
2018
This article provides a brief overview of the technology of humanoid robots. First, historical development and hardware progress are presented mainly on human-size full-body biped humanoid robots, together with progress in pattern generation of biped locomotion. Then, «whole-body motion» – coordinating leg and arm movements to fully leverage humanoids’ high degrees of freedom – is presented, followed by its applications in fields such as device evaluation and large-scale assembly. Upper-body humanoids with a mobile base, which are mainly utilized for research on human-robot interaction and cognitive robotics, are also introduced before addressing current issues and perspectives.
Environmental Data Processing by Clustering Methods for Energy Forecast and Planning
2011
This paper presents a statistical approach based on the k-means clustering technique to manage environmental sampled data to evaluate and to forecast of the energy deliverable by different renewable sources in a given site. In particular, wind speed and solar irradiance sampled data are studied in association to the energy capability of a wind generator and a photovoltaic (PV) plant, respectively. The proposed method allows the sub-sets of useful data, describing the energy capability of a site, to be extracted from a set of experimental observations belonging the considered site. The data collection is performed in Sicily, in the south of Italy, as case study. As far as the wind generation…
Climate Data Records of Vegetation Variables from Geostationary SEVIRI/MSG Data: Products, Algorithms and Applications
2019
The scientific community requires long-term data records with well-characterized uncertainty and suitable for modeling terrestrial ecosystems and energy cycles at regional and global scales. This paper presents the methodology currently developed in EUMETSAT within its Satellite Application Facility for Land Surface Analysis (LSA SAF) to generate biophysical variables from the Spinning Enhanced Visible and InfraRed Imager (SEVIRI) on board MSG 1-4 (Meteosat 8-11) geostationary satellites. Using this methodology, the LSA SAF generates and disseminates at a time a suite of vegetation products, such as the leaf area index (LAI), the fraction of the photosynthetically active radiation absorbed …
A Decision support system for sustainable operations management in small power plants
2014
The importance of environmentally-friendly electricity production is recognized as one of the most important challenges of our future, covering a broad context of research topics and promoting future scenarios based on renewable energies and new technologies. In the short term, however, energy generation will still be largely relying on power plants fired with fossil fuels whose emissions of pollutants are regulated by the industrial emissions directive in the EU legislation. Such directive does not apply to small and medium combustion plants, which until now, have only been subject to national regulations. As part of its air quality package from December 2013, the EU Commission has propose…
