(Universidad de Chile, 2016)Se presenta un modelo dinámico de múltiples mercados financieros, organizados como limit order markets, en el cual agentes endógenamente toman decisiones óptimas para maximizar el valor esperado de sus ganacias. Los ...
-
(Wiley, 2020)Production of biomass and lipids in batch cultures of the Antarctic thraustochytridOblongichytriumsp. RT2316-13, is reported. The microorganism proved capable of producing nearly 67% docosahexaenoic acid (DHA) and 15% ...

(Elsevier, 2022)Background By July 14, 2021, 81.3 % of adults (aged >= 18 years) in Chile had received a first SARS-CoV-2 vaccine and 72.3% had received a second SARS-CoV-2 vaccine, with the majority of people given Sinovac's inactivated ...

(Oxford University Press, 2017-05)We study the seismic source of the 2015 (M-w 6.7) Jujuy, Argentina intermediate depth earthquake. We first constrain the fault plane by using a teleseismic inversion and by determining the aftershock distribution. Then, ...
-
(Elsevier, 2018)In this paper, static and dynamic analyses were performed considering the reconstituted geometry of a prehistoric 0.1 km(2) rockslide with an exposed stepped-planar failure surface using a distinct element code (UDEC). The ...
-
(2004)Let K be the two-dimensional grid. Let q be an integer greater than 1 and let Q={0; : : : ; q−1}. Let s :Q → Q be de0ned by s( ) = ( + 1) mod q, ∀ ∈ Q. In this work we study the following dynamic F on QZ2 . For x ∈ QZ2 ...
-
(2009)We propose a strategy to perform query processing on P2P similarity search systems based on peers and superpeers. We show that by approximating global but resumed information about the indexed data in each peer, the ...
-
(Springer, 2015)Acoustic emission (AE) is very sensitive to minuscule molecular changes which allow it to be used in a dynamic control manner. The work presented here specifically investigates approaching grit and workpiece interaction ...
-
(Universidad de Chile, 2020)Although the origins of Revenue Management date back to its use by airlines in the post-deregulation era in the U.S., nowadays is heavily used by a variety of industries such as hotels, car rental companies and retailers. ...
-
(ICE Publishing, 2020)The paper describes the influence of 1-3% (by dry mass of sand) Laponite, a highly plastic synthetic nanoclay, on the dynamic properties of Ottawa sand, based on undrained resonant column tests. The effect of Laponite ...
-
(ELSEVIER, 2006-11-15)The digits of the square root of any real number can be consecutively calculated by hand with the use of a very popular exact algorithm. We show that the application of that algorithm defines a dynamic system in the sense ...
-
(IEEE, 2017)Clustering is one of the main data mining tasks with many proven techniques and successful real-world applications. However, in changing environments, the existing systems need to be regularly updated in order to describe ...
-
(Elsevier, 2020)Dynamic shear amplification has been commonly studied in cantilever reinforced concrete wall systems, how-ever, coupling beams or slabs can generate axial loads that can modify the response. A parametric study is carried ...
-
(2006-10-26)An important research issue in multimedia databases is the retrieval of similar objects. For most applications in multimedia databases, an exact search is not meaningful. Thus, much effort has been devoted to develop ...
-
(Pergamon-Elsevier, 2016)This paper presents the design and evaluation of a dynamic simulator for an ISCC (integrated solar combined cycle) plant. The design of the simulator is based on the phenomenological equations for both a combined cycle ...
-
(Elsevier, 2022)In this work, we have explored the dynamic properties of a Bloch Point singularity confined in a diameter modulated magnetic nanowire. By means of micromagnetic simulations, we have characterized the system when varying ...
-
(IEEE-Inst. Electrical Electronics Engineers, 2020)The satellite-terrestrial integrated networks (STINs) have gradually become a new class of effective ways to satisfy the requirements of a higher capacity and stronger connection in the future communications. In contrast ...
-
(2010)The work presents a data-model synthesis examining the response of the auroral F-region ion temperature, composition, and density to short time scale (<1 min) electric field disturbances associated with auroral arcs. ...
-
(Amer Inst Mathematical Sciences-Aims, 2015)ABSTRACT. For minimal Z 2 -topological dynamical systems, we introduce a cube structure and a variation of the usual regional proximality relation for Z 2 actions, which allow us to characterize product systems and ...
-
(IOP, 2020)We compare the observed turbulent pressure in molecular gas, P-turb, to the required pressure for the interstellar gas to stay in equilibrium in the gravitational potential of a galaxy, P-DE. To do this, we combine arcsecond ...
