(Universidad de Chile, 2008)En este trabajo presentamos un nuevo algoritmo para simulación de medios granulares densos que incluye partículas estáticas en presencia de gravedad. El modelo consiste en esferas duras inelásticas, para el cual contamos ...
-
(Institute of Physics (IoP), 2008)In the present work, an assessment of the Physics research capacity in Chile is presented. For this, the period between 2000 and June 2005 has been studied. In this period almost 200 physicists have contributed to ...
-
(IOP Publishing, 2014)A review of activities and future prospects of nuclear energy in Chile is presented. It shows that the development of this sector is closely linked to the history of the Chilean Nuclear Energy Commission, CCHEN, established ...
-
(Universidad de Chile, 2016)La fricción interna corresponde a la capacidad de los materiales de disipar la energía de ondas de sonido. Esta capacidad depende del tipo de material así como del tipo y cantidad de defectos que contenga. Durante muchos ...
-
(SPRINGER, 2010-04)A study of the vibrational density of states (DOS) of c-Al2O3 is presented. Four structural models from the recent literature are considered: vacant spinel model and three nonspinel models. The vacant spinel and one ...
-
(Springer, 2015)In this work we review the formalism used in describing the thermodynamics of first-order phase transitions from the point of view of maximum entropy inference. We present the concepts of transition temperature, latent ...
-
(Universidad de Chile, 2013)El principal objetivo de esta tesis es sentar las bases protocolares para la utilización del método Espectroscopía de Resonancia Ultrasónica No Lineal (NRUS, por sus siglas en in- glés) en la caracterización de la densidad ...
-
(Universidad de Chile, 2023)Estudiamos las dinámicas macroscópicas fuera del equilibrio que se obtienen a partir del principio de máximo calibre, determinando las hipótesis y restricciones que dan lugar a procesos irreversibles. Mostramos que los ...
-
(SPRINGER, 2010-05-15)Molecular dynamic (MD) simulations, both classical and ab initio, of amorphous GeO2 (germania), Al2O3 (alumina), and CdTeO compounds are presented. We focus our attention on the structural and vibrational properties, ...
-
(ELSEVIER SCIENCE BV, 2005-01-31)We investigate the dynamic properties of a classical anisotropic Heisenberg chain interacting with an external magnetic field at different temperatures. Properties such as time-dependent energy autocorrelation and space-time ...
-
(IOP PUBLISHING LTD, 2008-07-02)The classical action for a three-dimensional rotating particle with time-dependent angular velocity and that submitted to a general linear and quadratic time-dependent potential is explicitly calculated and, via path ...
-
(2013)The strength of key interfacial contacts that stabilize protein–protein interactions have been studied by computer simulation. Experimentally, changes in the interface are evaluated by generating specific mutations ...
-
(AMER INST PHYSICS, 2006-05-15)First-principles calculations of the single-crystal elastic constants of the body-centered cubic phase of bismuth are carried out in the pressure range of 31-191 GPa. The calculations are performed in the framework of ...
-
(Universidad de Chile, 2016)Los vidrios metálicos son aleaciones con una estructura atómica desordenada que han atraído interés durante las últimas décadas debido a sus propiedades mecánicas particulares como un alto módulo y límite elástico. Sin ...
-
(Universidad de Chile, 2021)El objetivo general de esta tesis es estudiar experimentalmente los materiales policristalinos, cuando éstos están creando y propagando dislocaciones. El principal interés de estudio de esta tesis nace de la física presente ...
-
(Universidad de Chile, 2009)El objetivo principal de esta tesis es el desarrollo de un protocolo experimental que permita medir de manera muy precisa las constantes elásticas en muestras de un mismo material pero que difieren significativamente en ...
-
(Universidad de Chile, 2006)El ob jetivo de nuestro trabajo es contribuir al estudio de la transición sólido-líquido en sistemas bidimensionales. Particularmente, pretende contrastar resultados numéricos generados por simulaciones de dinámica ...
-
(Elsevier, 2015)In this work, we report the heat rectifying capability of a-helices. Using molecular dynamics simulations we show an increased thermal diffusivity in the C-Terminal to N-Terminal direction of propagation. The origin of ...
-
(American Chemical Society, 2014)Recent evidence has shown a correlation between the heat diffusion pathways and the known allosteric communication pathways in proteins. Allosteric communication in proteins is a central, yet unsolved, problem in ...
-
(Springer-Verlag, 2014)We study how the opinions of a group of individuals determine their spatial distribution and connectivity, through an agent-based model. The interaction between agents is described by a Hamiltonian in which agents are ...
