(EDP SCIENCES S A, 2011-05)Context. In the framework of the multi-wavelength Galactic surveys of star-formation presently underway, complexes of molecular clouds that stretch over up to hundreds of parsecs are of particular interest. This is because ...
-
(Universidad de Chile, 2017)The following work is a study about wage inequality in Chile. Wage inequality is understood as the difference in total wages earned by the high earners and low earners. This thesis proposes a directed search model. This ...
-
(Universidad de Chile, 2023)El análisis automático de planos es un área dentro de la visión por computadora que ha sostenido un importante crecimiento en los últimos cinco años debido a un creciente interés de la industria por el desarrollo de ...
-
(Elsevier B.V., 2019)This paper investigates the limit properties of a sequence of competitive outcomes existing for economies where all commodities are indivisible, as indivisibility vanishes. The nature of this limit depends on whether the ...
-
(Springer, 2012)In this paper,we consider an exchange economywhere there is an external restriction for the consumption of goods. This restriction is defined by both, a cap on consumption of certain commodities and the requirement of ...
-
(IEEE, 2015)In this work, a WAMS-Based Voltage Stability Indicator considering real time operation conditions is proposed. The indicator considers operational limits, such as reactive power reserves, transmission constraints, ...
-
(Cambridge University Press, 2018)In this article, we provide sufficient conditions on a self-similar interval exchange map, whose renormalization matrix has complex eigenvalues of modulus greater than one, for the existence of affine interval exchange ...
-
(Elsevier, 2020)The coexistence of coherent and incoherent domains in discrete coupled oscillators, chimera state, has been attracted the attention of the scientific community. Here we investigate the macroscopic dynamics of the continuous ...
-
(Universidad de Chile, 2023)En este trabajo de tesis se estudia la dinámica simbólica en grupos finitamente generados. La motivación inicial de esta investigación fueron los resultados obtenidos por S. Piantadosi [42] en dinámica simbólica de grupos ...
-
(2009-10-02)New 12CO J=4–3 and 13CO J=3–2 observations of the N159 region, an active site of massive star formation in the Large Magellanic Cloud, have been made with the NANTEN2 and ASTE sub-mm telescopes, respectively. The 12CO ...
-
(Springer, 2015)A warm inflationary Universe in the Randall-Sundrum II model during intermediate inflation is studied. For this purpose, we consider the general form for the dissipative coefficient Gamma (T, phi) = C phi T-m/phi(m-1), and ...
-
(Springer, 2016)A warm intermediate inflationary model in the context of generalized Chaplygin gas is investigated. We study this model in the weak and strong dissipative regimes, considering a generalized form of the dissipative coefficient ...
-
(ESO, 2016-04)Context. The morphological, spectroscopic, and kinematical properties of the warm interstellar medium (wim) in early-type galaxies (ETGs) hold key observational constraints to nuclear activity and the buildup history of ...
-
(Springer, 2015)In the present work we show that warm chaotic inflation characterized by a simple λ4 φ4 self-interaction potential for the inflaton, excluded by current data in standard cold inflation, and by an inflaton decay rate ...
-
(The American Astronomical Society, 1995-11-10)We present observations of the (J, K) = (2, 2) and (3, 3) inversion transitions of ammonia, made at ˜4" resolution with the VLA, in the direction of the G32.80 + 0.19 and G61.48 + 0.09 star-forming regions, which contain ...
-
(Elsevier B.V., 2019)The forests in the Aysén region (ca. 43–49 °S, Chile) have a high degree of wilderness and cover more than 4.8 million hectares, making it one of the largest areas of subantarctic forest in the Southern Hemisphere. The ...
-
(Elsevier Ltd, 2019)© 2018 The main polysaccharide of the gel present in the leaves of or Aloe vera Burm.F., (Aloe barbadensis Miller) a xerophytic crassulacean acid metabolism (CAM) plant, is an acetylated glucomannan named acemannan. This ...
-
(American Society for Enology and Viticulture, 2019)Crimson Seedless is one of the most important table grape cultivars in the world, but often exhibits uneven berry color when grown in warm climates. Deficit irrigation is used extensively by growers during the ripening ...
-
(Universidad de Chile, 2021)La presente tesis tiene como objetivo el generar una metodología de análisis de riesgo sísmico para una red de agua potable deteriorada por el tiempo. Esta metodolgía se divide en 6 partes: i) análisis hidráulico de la red ...
-
(Springer, 2021)Water quality in Chile is characterized by diverse hydrochemical environments and their interaction with human activities and natural factors. The main water monitoring network is operated by the DGA (Dirección General de ...
