The Effect of Low-pass Pre-filtering on Subvoxel Registration Algorithms in Digital Volume Correlation: A revisited study
Authors: Zou Xiang , Li Kai , Pan Bing 
Published: November 2020

Abstract
In digital volume correlation (DVC), random image noise in volumetric images leads to increased systematic error and random error in the displacements measured by subvoxel registration algorithms. Previous studies in DIC have shown that adopting low-pass pre-filtering to the images prior to the correlation analysis can effectively mitigate the systematic error associated with the classical forward additive Newton-Raphson (FA-NR) algorithm. However, the effect of low-pass pre-filtering on the state-of-the-art inverse compositional Gauss-Newton (ICGN) algorithm has not been investigated so far. In this work, we focus on the effect of low-pass pre-filtering on two mainstream subvoxel registration algorithms (i.e., 3D FA-NR algorithm and 3D IC-GN algorithm) used in DVC. Basic principles and theoretical error analyses of the two algorithms are described first. Then, based on numerical experiments with precisely controlled subvoxel displacements and noise levels, the influences of image noise on the displacements measured by two subvoxel algorithms are examined. Further, the effects of low-pass pre-filtering on these two subvoxel algorithms are examined for simulated image sets with different noise levels and deformation modes. The results show that the low-pass pre-filtering can effectively suppress the systematic errors for the 3D FA-NR algorithm, which is consistent with the previously drawn conclusion in DIC. On the contrary, different form the 3D FA-NR algorithm, the 3D IC-GN algorithm itself can reduce the influence of image noise, and the effect of low-pass pre-filtering on it is not so obvious as on 3D FA-NR algorithm.
Using a Gauge Block for Derivation of Parameters of Four Laser Triangulation Sensors in a Local Coordinate System
Authors: Buša Ján , Dovica Miroslav , Zhabitsky Mikhail 
Published: November 2020

Abstract
The paper discusses the derivation of an accurate coordinate measuring system consisting of two, three, or four sensors based on the records of four fixed laser triangulation sensors done for a gauge block in movement. Three-dimensional case is considered. In the simulations, using a set of distances quadruplets, parameters of sensors in a local sensors coordinate system are determined through a least squares minimization process using the Differential Evolution approach. The influence of the measurement and rounding inaccuracy on the identification accuracy using numerical simulation methods are assessed.
Electromagnetic Shielding Performance Measurement for Braided-Shield Power Cables at Low Frequency Regimes
Authors: Zhou Zhongyuan , Hu Peng , Zhou Xiang , Sheng Mingjie , Li Peng , Zhou Qi 
Published: November 2020

Abstract
Although various measurement techniques have been applied to both qualitative and quantitative evaluation for the electromagnetic shielding performance of braided-shield power cables, the existing measurements cannot directly assess the low-frequency shielding performance (typically below 100 kHz) due to factors such as ground-loop effects and dynamic range problem in measurement. To solve these, an improved shield reduction factor method, based on gain (T/R) rather than scattering parameters, is proposed to evaluate the shielding performance of braided-shield power cables from 25 Hz to 1 MHz. In this work, we highlight the implementation of measurement setup to avoid the effects of ground-loop and stray electromagnetic field. Meanwhile, the test cell is simplified according to the definition of the shield reduction factor in order to obtain the gain (T/R) parameters, which can be used to calculate transfer impedance as well. From the measurements we present more intuitive evaluation of shielding behavior of braided-shield power cables at low frequency regimes, and showcase a detailed comparative discussion between transfer impedance and shield reduction factor. The proposed shield reduction factor method is expected to be a useful way for the evaluation of the low frequency shielding performance of braided-shield cables.
The identity of Azara’s description No. 18 “Gavilán mixto pintado” is a juvenile Harris’s hawk (Parabuteo unicinctus)
Authors: Smith Paul 
Published: November 2020

Abstract
The classic ornithological work by Félix de Azara “Apuntamientos para la historia natural de los páxaros del Paraguay y Rio de la Plata” was one of the first descriptive texts dealing with the avifauna of the Southern Cone of South America. Azarays No. 18 vGavilán mixto pintadow has long been misidentified as a juvenile great black hawk (Buteogallus urubitinga ((Gmelin, 1788)). However, there are clear inconsistencies in the description of the plumage coloration, shape and measurements which make that identification erroneous, and Azarays No. 18 can in fact be convincingly identified as the juvenile plumage of the Harrisys hawk (Parabuteo unicinctus (Temminck, 1824)). The description by Azara contains numerous diagnostic characteristics for that species, and the measurements provided by him are inconsistent with those of the great black hawk, yet remarkably similar to those provided by the same author for the description of the adult No. 19 vGavilán mixto obscuro y canelaw. No scientific names have apparently ever been based on Azara No. 18.

Ciclo Escena y Memoria: una rebeldía amorosa
Authors: Alegret Mauro 
Published: November 2020

En el presente trabajo se abordan dos eventos teatrales: la representación de la obra Villa, del dramaturgo chileno Guillermo Calderón, y el Ciclo Escena y Memoria, coordinado por Jorge Villegas. Ambos eventos tuvieron lugar en el campo teatral independiente de la ciudad de Córdoba, Argentina, durante el año 2019. Desde una perspectiva sociohistórica abordamos la relación de dichos eventos con el ejercicio de la memoria en la ciudad. De Villa retomamos las actuales inquietudes respecto al uso político de los sitios de la memoria, para formular la pregunta: ¿es posible representar el horror del terrorismo de Estado? Del Ciclo nos interesan las redefiniciones respecto al cruce entre teatro y militancia política, y la habilitación de nuevos espacios de comunidad social a partir del dolor de los cuerpos.AbstractThis article addresses two theatrical events: the play Villa, by Chilean playwright Guillermo Calderón, and the Performing Arts and Memory Cycle, coordinated by Jorge Villegas. Both were produced in 2019 as part of the independent theater scene in the city of Córdoba, Argentina. These events are discussed from a socio-historical perspective, in order to understand the how they are related to the city’s collective memory. In Villa it’s possible to identify the political use of the memory sites and how Calderón works with a fundamental question: is it possible to represent the horror of State terrorism? In the Performing Arts and Memory Cycle, the author discusses the intersection between theatre and political militancy, and the enabling of new spaces for social community where bodies have been subjected to pain.

La (in)visibilidad de las escenógrafas mexicanas (1950-1990)
Authors: Ruíz Rivera Patricia 
Published: November 2020

En el relato de la historia de la escenografía en México hace falta incluir a las mujeres; es una deuda pendiente. La memoria institucionalizada, en tanto política heteropatriarcal, las ha invisibilizado por medio del silencio que guardan las fuentes sobre su trabajo y por omisión en el relato histórico del teatro mexicano del siglo xx. Este trabajo es un apunte sobre la manera en que se ha construido esa memoria y acerca de la necesidad de hacer visible lo invisible.The (In)visibility of Mexican Women Stage Designers (1950-1990)AbstractThe inclusion of women in the history of stage and set design in Mexico is long overdue. The institutionalized memory, with its hetero-patriarchal politics, has rendered women stage designers invisible. They are largely ignored in diverse documentary sources, as in the historical account of twentieth century Mexican theater. This article addresses the diverse ways women have been elided from archival sources, calling for the urgent need to make visible their contribution.

CHILE ENTRE EL PROTAGONISMO PRODUCTIVO DE PIELES DE GANADOS MENORES Y EL REZAGO COMERCIAL COMPETITIVO REGIONAL. ANÁLISIS A PARTIR DE UNA RED MERCANTIL LOCAL/REGIONAL (FINALES DEL SIGLO XVIII)
Authors: Soler Consuelo 
Published: November 2020

En las dos últimas décadas del siglo XVIII el virreinato del Río de la Plata aumentó la exportación de cueros hacia ultramar, resultado de la captura productiva de los mercados internos y del nexo de los comerciantes locales con la metrópoli. Algo semejante ocurrió en Perú, al comercializar cueros producidos localmente y en áreas de su influencia hacia la América septentrional. En ese contexto, el estudio resalta cómo a partir de esta división operativa, los tradicionales proveedores subregionales quedaron en desventaja para ofertar sus pieles de ganados menores. Por correspondencia privada y fuentes institucionales, se analiza la dinámica interna de la producción, distribución, tráfico y comercializaciónprincipalmente de cordobanes, desde los lugares productivos de origen hacia las plazas o mercados comercializables. En síntesis, se argumentan los factores que explican dónde y por qué los famosos cordobanes, badanas y pellones chilenos rezagaron sus exportaciones interregionales.
ABSTRACT
In last two decades of the 18th century the viceroyalty of the Silver increased the export of leather towards overseas ensued from the productive capture of the internal markets and of the link of the local merchants with the bureaucratic device. Something similar happened in Peru, on having commercialized leather produced locally and in areas of his influence towards the north America. In this context, the study highlights how from this operative division, the traditional sub regional suppliers stayed in disadvantage to offer his skins of minor cattles. For private correspondence and institutional sources, there is analyzed the internal dynamics of the production, distribution, traffic and commercialization principally of cordovans, from the productive places of origin towards the squares or marketable markets. In synthesis, there are argued the factors that explain where and why the famous cordovans, shepskin and pellones Chileans.left his interregional exports behind

LA ANTIGUA PALMA Y LA ACTUAL HUMBERSTONE. UN COMPLEJO PATRIMONIAL Y UN PAISAJE CULTURAL PAMPINO
Authors: Ojeda Berger Orietta 
Published: November 2020

La declaratoria de las salitreras Humberstone y Santa Laura, como Patrimonio Histórico de la Humanidad el año 2005 por parte de la UNESCO, destacó a estas ruinas salitreras por sobre sus similares, transformándolas en plataformas culturales para la protección de los vestigios históricos de lo que fue el ciclo del nitrato de Chile. Sin embargo invisibilizó a la oficina La Palma, la que vio modificado su diseño urbano e industrial en 1934, cambiando también su nombre por el de Humberstone, teniendo por resultado un paisaje cultural nuevo, que incluía las salitreras del llamado Grupo Nebraska (Cala Cala, Santa Laura, Peña Chica, Keryma y campamento don Guillermo). Aquí se rescata la historia de La Palma,cuya ruina aún persiste yuxtapuesta a la de Humberstone, proponiéndose, una nueva definición para la UNESCO: Complejo patrimonial La Palma- Humberstone- Santa Laura.
ABSTRACT
Declaratory judgement of Humbertone and Santa Laura saltpeter towns, as world historic heritage in 2005 by UNESCO, emphasizes these saltpeter mine ruins above their similar ones, turning them into cultural platforms to protect the remains of the history of nitrate. Nevertheless, it overshadowed La Palma saltpeter town, which urban and industrial design was transformed in 1934, changing its name into Humberstone, resulting in a new cultural landscape that included Grupo Nebraska saltpeter towns (Cala Cala, Santa Laura, Peña Chica, Keryma and Don Guillermo Camp.). Here the history of La Palma is recovered, which ruin still overlaps Humbertone’s, suggesting a new definition for UNESCO: Heritage Complex La Palma –Humberstone- Santa Laura.
LOS LÍMITES DEL RECONOCIMIENTO EN CHILE: LA COMISIÓN DE VERDAD HISTÓRICA Y NUEVO TRATO Y UN VOTO DE MINORÍA
Authors: Espinoza Araya Claudio 
Published: November 2020

A partir de la revisión del Informe de la Comisión de Verdad Histórica y Nuevo Trato, publicado en 2003, este artículo busca reflexionar sobre uno de los elementos teóricos e ideológicos que han impedido instalar en el Estado una perspectiva amplia de reconocimiento intercultural. Se sostiene que eltratamiento de la cuestión indígena en Chile ha estado mayormente dominado por una perspectiva liberal no pluralista y por un indigenismoasimilacionista e integracionista. Para ello se revisan, de modo general, las grandes propuestas emitidas por el Informe de la Comisión y, sobre todo, la opinión de minoría expuesta por uno de los comisionados, opinión que, a pesar de su carácter minoritario en dicho informe, parece ser hegemónica encuanto al accionar del Estado chileno.
From the review of Comisión de Verdad Histórica y Nuevo Trato report, published in 2003, this article seeks to reflect on one of the theoretical and ideological elements that has prevented to install in the State a wide perspective of intercultural recognition. It is argued that the treatment of the indigenous question in Chile has been dominated mainly by a non-pluralistic liberal perspective and by an assimilationist and integrationist indigenism.To this end, are reviewed in general, the major propposals issued by the commission’s report and, especially, the minority opinion expressed by one of the commissioners, an opinion that, despite its minority nature in said report, seems to be hegemonic regarding the action s of the Chilean State.

Published: November 2020

Due to the rapid development of digital technology, the structure of future jobs is becoming increasingly complex, and university graduates need to acquire the right combination of skills to succeed in a rapidly changing world. The need for continuous replenishment and updating of professional knowledge is determined by the pace of scientific and technological progress, the transition to the information stage of the development of society, and the widespread use of innovative technologies. There are prerequisites for the formation and development of the category of “strategic outsourcing”. Unlike the services of the service, which have a one-time, episodic nature, strategic outsourcing is usually transferred to the functions of professional support for the uninterrupted operation of individual systems and infrastructure based on a long-term contract. Strategic outsourcing allows not only to restructure business processes radically but also significantly improve opportunities and prospects. The purpose of this study is to study the concept of outsourcing in entrepreneurial training and the development of human capital.
