Bases del sistema de seguridad social y sus paradigmas en transformación a proposito de la Constitución Chilena.
2019
Working paper sobre Chile en el contexto Iberoamericano, que ha mostrado un fuerte desarrollo en temas de seguridad social, cabe destacar que desde inicios del Siglo XX, los trabajadores asalariados, o sea aquellos que estaban adscritos al sistema formal de trabajo, contaban con instituciones preocupados de su protección como la llamada: Caja del Seguro Obrero Obligatorio, y otras cajas que surgieron . Esta institucionalidad fue heredera de las políticas impulsadas por Bismarck a finales del Siglo XIX, inspiradores de este sistema de Cajas de ahorro y Seguro Social . En este sentido en la década de los 80 del siglo XX, con el inicio del gobierno militar de Augusto Pinochet, este propugna un…
Design of a customized pattern for improving color constancy across camera and illumination changes
2010
International audience; This paper adresses the problem of color constancy on a large image database acquired with varying digital cameras and lighting conditions. Automatic white balance control proposed by an available commercial camera is not sufficient to provide reproducible color classification. A device-independent color representation may be obtained by applying a chromatic adaptation transform, from a calibrated color checker pattern included in the field of view. Instead of using the standard Macbeth color checker, we suggest to select judicious colors to design a customized pattern from contextual information. A comparative study demonstrates that this approach insures a stronger…
Riannodare passato e presente con le foto d’archivio. Ricostruzione della chiesa delle Stimmate di Palermo
2021
La restituzione prospettica è stata pressoché ignorata nelle ricerche incentrate sulla ricostruzione di architetture e contesti urbani da foto d’archivio, a causa dell’ampio margine di approssimazione che caratterizzava il processo di restituzione condotto con gli strumenti tradizionali del disegno. Gli strumenti digitali per la rappresentazione riducono sensibilmente il margine di approssimazione e permettono di ricostruire direttamente nello spazio tridimensionale le opere che compaiono in una singola immagine fotografica. Il caso studio prescelto è la chiesa delle Stimmate di Palermo, demolita alla fine del XIX secolo per la costruzione del teatro Massimo, principale teatro lirico della …
Una capitale intermittente: la vicenda di Antiochia di Siria nel IV secolo d.C.
2020
Thanks to the mass of information that can be extrapolated from Libanius of Antioch, it is possible to select the two facies of the city on the Oronte in Late Antiquity, i.e. Antioch as administrative capital (of the province of Syria; of the Diocese of the East), and Antioch as imperial capital (although not in the strict sense: but the city played the role of ‘episodic capital’). This contribution aims at focusing on Antioch as ‘imperial capital intermittently’, highlighting: the implications both at economic- logis- tical (supply related to the presence of the court) and urban-monumental level (new buildings already starting from Diocletian) as well as the relationship with the other cit…
Smart Micro-Grid Performance using Renewable Energy
2020
The aim of this research is to determine the performance of PV panels, wind turbines, battery storage and power imported from the grid to the system which will ensure a reliable energy supply, as well as the technical feasibility of a smart microgrid system. Indonesia’s renewable energy potential for electricity reaches 443 GW, where solar energy is the largest potential, namely 4.8 KWh m–2 or equivalent to 112 000 GWp, but only 10 MWp has been utilized. The most basic problem in this system, namely, the uncertainty of wind energy and solar energy, one of the most vital factors in the optimal size of a renewable energy-based smart microgrid system is the reliability of the system being buil…
Multiscale variation in drought controlled historical forest fire activity in the boreal forests of eastern Fennoscandia
2017
Forest fires are a key disturbance in boreal forests, and characteristics of fire regimes are among the most important factors explaining the variation in forest structure and species composition. The occurrence of fire is connected with climate, but earlier, mostly local-scale studies in the northern European boreal forests have provided little insight into fire-climate relationship before the modern fire suppression period. Here, we compiled annually resolved fire history, temperature, and precipitation reconstructions from eastern Fennoscandia from the mid-16th century to the end of the 19th century, a period of strong human influence on fires. We used synchrony of fires over the network…

La jurisprudencia del Tribunal Constitucional chileno sobre tratados internacionales: el específico caso de las cláusulas autoejecutables y no autoej…
2016
El presente trabajo se pronuncia sobre el tratamiento específico que ha dado la magistratura constitucional chilena a la cuestión de las cláusulas autoejecutables y no autoejecutables de los tratados internacionales, y sobre si dicho tratamiento es adecuado conforme al sistema constitucional de incorporación y vigencia del derecho convencional internacional en el ordenamiento jurídico nacional. This paper deals with the specific treatment that has given the Constitutional Court of Chile on the question of self-executing and non-self-executing provisions of international treaties, and whether the treatment is appropriate under the constitutional system of incorporation and validity of intern…
Macro-micro relationship in nanostructured functional composites
2012
This paper examines the results of the characterization of two functional composites: Poly(methyl methacrylate) (PMMA)-Ce:YAG (yttrium aluminium garnet doped with cerium) and PMMA-cobalt hexacyanoferrate (CoHCF). The composites were prepared as possible emitters in the fields of lighting thermal sensors. The prepared composites were char- acterized using transmission electron microscopy (TEM), nuclear magnetic resonance (NMR) spectroscopy, thermogravi- metric analysis (TGA), differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA) analyses to study the correlation between micro and macro characteristics. We found that the molecular interactions of the two different fill…
