Reception of the Second Vatican Council in Tucumán, 1965-1973

A mediados de la década de 1960 finalizaba el Concilio Vaticano II, uno de los hitos más importantes del mundo católico del siglo XX. Los documentos elaborados plantearon una renovación de ciertos aspectos en lo litúrgico así como también en la concepción de la misión pastoral, que no significaron necesariamente una ruptura sino más bien un aggiornamiento ante los cambios culturales, sociales y políticos de toda la primera mitad del siglo y que parecían llegar a un punto de efervescencia en la década del '60. En este caso nos interesa analizar las repercusiones del Concilio Vaticano II en el mundo católico tucumano, así como los cambios y las continuidades que se pueden reconocer a partir de este hecho. Cabe destacar que Tucumán vivía, en el período que aquí se abarca, un momento particular con respecto al mundo eclesiástico así como a la realidad político-económica. A partir de lo señalado, entonces, nos interesa dar cuenta de las voces que se superponen en el seno de un catolicismo heterogéneo, y la articulación entre el discurso renovado de la Iglesia con la realidad local.The Vatican Council II, one of de most important landmarks of twentieth century Catholic world, ended in the mid 1960s. Te documents produced proposed a re- newal in some liturgical aspects as well as in the conception of the pastoral mission. Tey did not necessarily mean a break but rather an updating to acknowledge the cultural, social and political changes of the frst half of the century that seemed to reach a point of efervescence in the ‘60s. In this case we want to analyze the impact of the Second Vatican Council in the catho- lic world of Tucuman, and the alterations and continuities that can be recognized from this event. It should be noted that Tucumán was liv- ing a particular moment with regard to the ecclesiastical world as well as to the politi- cal and economic reality in the period cov- ered here. Thus, from these data, we want to account for overlapping voices within heteroge- neous Catholicism, and the articulation be- tween the Church’s renewed dicourse and local reality.Fil: Schkolnik, Iris.

Performance seeking control excitation mode

Flight testing of the performance seeking control (PSC) excitation mode was successfully completed at NASA Dryden on the F-15 highly integrated digital electronic control (HIDEC) aircraft. Although the excitation mode was not one of the original objectives of the PSC program, it was rapidly prototyped and implemented into the architecture of the PSC algorithm, allowing valuable and timely research data to be gathered. The primary flight test objective was to investigate the feasibility of a future measurement-based performance optimization algorithm. This future algorithm, called AdAPT, which stands for adaptive aircraft performance technology, generates and applies excitation inputs to selected control effectors. Fourier transformations are used to convert measured response and control effector data into frequency domain models which are mapped into state space models using multiterm frequency matching. Formal optimization principles are applied to produce an integrated, performance optimal effector suite. The key technical challenge of the measurement-based approach is the identification of the gradient of the performance index to the selected control effector. This concern was addressed by the excitation mode flight test. The AdAPT feasibility study utilized the PSC excitation mode to apply separate sinusoidal excitation trims to the controls - one aircraft, inlet first ramp (cowl), and one engine, throat area. Aircraft control and response data were recorded using on-board instrumentation and analyzed post-flight. Sensor noise characteristics, axial acceleration performance gradients, and repeatability were determined. Results were compared to pilot comments to assess the ride quality. Flight test results indicate that performance gradients were identified at all flight conditions, sensor noise levels were acceptable at the frequencies of interest, and excitations were generally not sensed by the pilot

The effect of wavefront aberrations in atom interferometry

Wavefront aberrations are one of the largest uncertainty factors in present atom interferometers. We present a detailed numerical and experimental analysis of this effect based on measured aberrations from optical windows. By placing windows into the Raman beam path of our atomic gravimeter, we verify for the first time the induced bias in very good agreement with theory. Our method can be used to reduce the uncertainty in atomic gravimeters by one order of magnitude resulting in an error of less than $3\times 10^{-10}\,g$ and it is suitable in a wide variety of atom interferometers with thermal or ultra cold atoms. We discuss the limitations of our method, potential improvements and its role in future generation experiments.Comment: Applied Physics B, 201

El mundo del trabajo y la revista Criterio, un vínculo conflictivo (1966-1979)

En el siguiente trabajo indagamos la configuración discursiva de la revista Criterio sobre el mundo del trabajo durante la segunda mitad de la década de 1960. Los cambios producidos en el seno del catolicismo no fueron asimilados de manera uniforme por todo el espectro eclesiástico y laico. En general, los análisis que abordan las relaciones entre el mundo del trabajo y el catolicismo en dicho periodo han estudiado a los sectores más radicalizados. Criterio, en contraste, se presenta como representante de un catolicismo moderado. La publicación indica fuertemente la necesidad de articular los intereses y de moderar los espíritus en pos de un proceso que recién se desplegaba, la Revolución Argentina. En concreto, Criterio no se dirigía a los trabajadores o a los sindicatos, sino claramente a las cumbres institucionales de la clase empresarial. En efecto, la publicación delineaba un paternalismo empresario de corte modernizante.In this paper we inquire into the discursive configuration of Criterio catholic magazine about the realm of work during the second half of the 1960s. The changes within Catholicism were not uniformly assimilated through all ecclesiastical and secular spectrums. In general, the previous analyses that have addressed the relationship between the realm of work and Catholicism in this period have usually studied the most radical scopes. Criterio, in contrast, is presented as representative of a moderate Catholicism. & e publication strongly indicates the need to articulate interests and moderate spirits after a processthat was just unfolding, the Argentinean Revolution. Specifically, Criterio was not addressed at workers or unions, but at the institutional summits of the business class. Indeed, the publication depicted an entrepreneurial paternalism with some modernizing aspects.Fil: Pattin, Sebastian Pedro. Consejo Nacional de Investigaciones Científicas y Técnicas.

Flight test validation of a frequency-based system identification method on an F-15 aircraft

A frequency-based performance identification approach was evaluated using flight data from the NASA F-15 Highly Integrated Digital Electronic Control aircraft. The approach used frequency separation to identify the effectiveness of multiple controls simultaneously as an alternative to independent control identification methods. Fourier transformations converted measured control and response data into frequency domain representations. Performance gradients were formed using multiterm frequency matching of control and response frequency domain models. An objective function was generated using these performance gradients. This function was formally optimized to produce a coordinated control trim set. This algorithm was applied to longitudinal acceleration and evaluated using two control effectors: nozzle throat area and inlet first ramp. Three criteria were investigated to validate the approach: simultaneous gradient identification, gradient frequency dependency, and repeatability. This report describes the flight test results. These data demonstrate that the approach can accurately identify performance gradients during simultaneous control excitation independent of excitation frequency
