(2006)We study the three-dimensional distribution of non-virialized matter at z ∼ 2 using highresolution spectra of quasi-stellar object (QSO) pairs and simulated spectra drawn from cosmological hydrodynamical simulations.We ...
-
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2008-09)Automated consistency checking of UML models becomes necessary as models grow in size and complexity. Since the UML metamodel does not enforce model consistency, there are no fixed guidelines on how to approach the ...
-
(Springer, 2014)This paper analyzes feeding strategies in a sequential batch reactor (SBR) with the objective of reaching a given (low) substrate level as quickly as possible for a given volume of water. Inside the SBR, several species ...

(Springer, 2017)LetD={T1,T2,...,TD}be a collection ofDstring doc-uments ofncharacters in total, that are drawn from an alphabet setΣ= [σ]. Thetop-kdocument retrieval problemis to preprocessDintoa data structure that, given a ...
-
(Universidad de Chile, 2021)En esta tesis se estudia una serie de problemas en combinatoria extremal y probabilista relacionados a árboles y palabras. En la primera parte de este trabajo se estudian qué condiciones debe cumplir un grafo para que ...
-
(Universidad de Chile, 2020)Esta tesis consiste de dos partes. En la parte I, se modelan los grados de libertad magnéticos en el imán bidimensional de van der Waals CrI3. Se comienza desde un cálculo ab initio obtenido, mediante la aproximación de ...
-
(American Physical Society (APS), 2020)We report on a study of a one-dimensional linear photonic lattice hosting, simultaneously, fundamental and dipolar modes at every site. We show how, thanks to the coupling between different orbital modes, this minimal model ...
-
(Amer Inst Mathematical Sciences-AIMS, 2021)A linear system of di erence equations and a nonlinear perturbation are considered, we obtain su cient conditions to ensure the topological equivalence between them, namely, the linear part satis es a property of ...
-
(Amer Physical Soc, 2020)We report on the magnon spectrum of Kitaev-Heisenberg magnets and extract the parameters to model a two-dimensional CrI3. Our minimal spin Hamiltonian includes a contribution stemming from a Heisenberg, isotropic exchange, ...
-
(Universidad de Chile, 2023)La mecánica topológica es un campo emergente que combina conceptos de la mecánica clásica y las fases topológicas de la materia estudiadas en la teoría de la materia condensada. En este campo, la topología no trivial de ...
-
(MDPI, 2021)Mobile robots are no longer used exclusively in research laboratories and indoor controlled environments, but are now also used in dynamic industrial environments, including outdoor sites. Mining is one industry where ...
-
(IOP, 2016)We study the spin waves of the triangular skyrmion crystal that emerges in a two-dimensional spin lattice model as a result of the competition between Heisenberg exchange, Dzyalonshinkii-Moriya interactions, Zeeman coupling ...
-
(Springer Verlag, 2018)Recently, the search for topological states of matter has turned to non-Hermitian systems, which exhibit a rich variety of unique properties without Hermitian counterparts. Lattices modeled through non-Hermitian Hamiltonians ...
-
(Nature, 2020)Matter under different equilibrium conditions of pressure and temperature exhibits different states such as solid, liquid, gas, and plasma. Exotic states of matter, such as Bose-Einstein condensates, superfluidity, chiral ...
-
(Universidad de Chile, 2015)Este estudio se realizó en el Centro Avanzado de Manufactura [AMRC], Universidad de Sheffield, Reino Unido, dentro de su programa Proving Factory, que busca dar soporte a las industrias para optimizar sus procesos de ...

-
(Springer, 2019)Records of extreme altitudes where several coccinellid species from South America inhabit the Andes of Argentina, Bolivia, Chile, Colombia, Ecuador, and Peru are provided. After an intensive review of several entomological ...
-
(Universidad de Chile, 2017)El objetivo de la presente memoria, es evaluar como plan de negocio el desarrollo de un tour operador receptivo enfocado en el mercado indio. El concepto de turismo enfocado en el mercado indio, está escasamente desarrollado ...
-
(Universidad de Chile, 2017)Desde el año 2012 China es el líder indiscutido en el mercado turístico emisor en el mundo. El 2015 se registraron128 millones de salidas al extranjero, dejando un sorprendente gasto por turismo internacional de USD 292 ...
-
(AMER METEOROLOGICAL SOC, 2006-10-15)An important goal of the Climate Variability and Predictability (CLIVAR) research on the American monsoon systems is to determine the sources and limits of predictability of warm season precipitation, with emphasis on ...
