(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 ...
-
(IOP, 2020)More than a dozen young stars host spiral arms in their surrounding protoplanetary disks. The excitation mechanisms of such arms are under debate. The two leading hypotheses-companion-disk interaction and gravitational ...
-
(WORLD SCIENTIFIC PUBL, 2016)We propose a simple model of landfill and study a minimal time control problem where the re-circulation leachate is the manipulated variable. We propose a scheme to construct the optimal strategy by dividing the state ...

Dynamical models to explain observations with SPHERE in planetary systems with double debris belts (EDP Sciences, 2018)Context. A large number of systems harboring a debris disk show evidence for a double belt architecture. One hypothesis for explaining the gap between the debris belts in these disks is the presence of one or more planets ...
-
(Royal Soc, 2016)We compare two different notions of dynamical phase transitions in closed quantum systems. The first is identified through the time-averaged value of the equilibrium-order parameter, whereas the second corresponds to ...
-
(Elsevier, 2015)It is shown that a single molecular magnet placed in a rapidly oscillating magnetic field displays the phenomenon of quenching of tunneling processes. The results open a way to manipulate the quantum states of molecular ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2003-11-20)We study the existence of singular separable solutions to the 2-dimensional quasilmear equation -del(.) (\delu\(p-2)delu) + \u\(q-1) u = 0 under the form u(r, theta) = r(-beta)omega(theta). We obtain the full description ...
-
(Universidad de Chile, 2023)La masa es el parámetro fundamental que determina la estructura y evolución de una estrella. Sin embargo, medir la masa de las estrellas no es una tarea fácil, por lo que el número de estrellas con masas bien conocidas ...

A dynamically-packed planetary system around GJ 667C with three super-Earths in its habitable zone (EDP Sciences, 2013-08)Context. Since low-mass stars have low luminosities, orbits at which liquid water can exist on Earth-sized planets are relatively close-in, which produces Doppler signals that are detectable using state-of-the-art Doppler ...
-
(Elsevier, 2020)Volcanic debris avalanches are extremely destructive phenomena, with the potential to travel many kilometers from their source region, either as rockslides or as mass flows. Given that they may even be triggered at inactive ...
-
(IOP Publishing, 2020)This paper introduces a new consideration in the well known chemostat model of a one-species with a periodic input of single nutrient with period omega, which is described by a system of differential delay equations. The ...
-
(American Physical Society, 2014)Agranular system confined in a quasi-two-dimensional box that is vertically vibrated can transit to an absorbing state in which all particles bounce vertically in phase with the box, with no horizontal motion. In principle, ...
-
(Institute of Mathematical Statistics, 2018)We study the long-time behavior of the dynamics of interacting planar Brownian particles, confined by an external field and subject to a singular pair repulsion. The invariant law is an exchangeable Boltzmann – Gibbs ...
-
(AMER Geophysical Union, 2021)The 2004-2009 caldera uplift is the largest instrumentally recorded episode of unrest at Yellowstone caldera. We use GPS and Interferometric Synthetic Aperture Radar (InSAR) time series spanning 2004-2015, with a focus in ...
