(Springer, 2017)This paper is the first in a two-part work, where the investigation into the characteristics of multiple machine processes is made in order to accurately control them via the frequently used machine centre platform. The ...
-
(2017)Part 2 of this work looks at the simulation for the accurate control of multiple machine processes made on a machining centre. Specifically the models are based on controlling against two grinding anomalies; grinding burn ...
-
(Taylor & Francis, 2021)Let Sigma be a surface of constant mean curvature in R-3 with multiple Delaunay ends. Assuming that Sigma is non degenerate in this paper we construct new solutions to the Cahn-Hilliard equation epsilon Delta u + epsilon(-1)u(1 ...

(Elsevier, 2022)While MRI allows to encode the motion of tissue in the magnetization's phase, it remains yet a challenge to obtain high fidelity motion images due to wraps in the phase for high encoding efficiencies. Therefore, we propose ...
-
(Elsevier, 2006)By describing the technical process, in this article we argue that cargothat arrives in many different forms are distinct outputs of a port, whose services require inputs that can be grossly defined as labor, space, ...
-
(Elsevier, 2016)The coherent propagation of elastic waves in a solid lled with a random distribution of pinned dislocation segments is studied to all orders in perturbation theory. It is shown that, within the independent scattering ...
-
(Universidad de Chile, 2019)Dado un conjunto finito de N vértices, el tiempo de viaje entre cada uno de ellos, una cantidad m de vehículos y un punto de origen llamado depósito, en el multiple traveling salesman problem se desea encontrar m rutas ...
-
(2010)We construct a new class of entire solutions for the Allen-Cahn equation u + (1 u2)u = 0, in R2( C). Given k 1, we nd a family of solutions whose zero level sets are, away from a compact set, asymptotic to 2k ...
-
(INT PRESS BOSTON, 2015)zeta-regularized determinants are well-known to fail to be multiplicative, so that in general det(zeta)(AB) not equal det(zeta)(A) det(zeta)(B). Hence one is lead to study the n-fold multiplicative anomaly M-n(A(1),..., ...
-
(2016)We report new CHARA/Michigan InfraRed Combiner interferometric observations of the Cepheid archetype delta Cep, which aimed at detecting the newly discovered spectroscopic companion. We reached a maximum dynamic range Delta ...
-
(Universidad de Chile, 2013)Esta tesis contiene cinco cap\'{i}tulos. En el primer cap\'{i}tulo, presentamos algunas motivaciones de los problemas que consideramos en los siguientes cuatro cap\'{i}tulos. En particular, describimos algunos resultados ...
-
(Springer, 2020)Reservoir operations often require balancing among several water uses. Despite the non-consumptive nature of hydropower, conflicts exist between irrigation and hydropower due to a demand seasonality mismatch. Hydropower ...
-
(MDPI, 2020)Speech enhancement is one of the most important fields in audio and speech signal processing. The speech enhancement methods are divided into the single and multi-channel algorithms. The multi-channel methods increase the ...
-
(Blackwell Publishing Ltd, 2019)Using data from Defense Meteorological Satellite Program 16–18, National Oceanic and Atmospheric Administration 15–19, and METOP 1–2 satellites, we reconstructed for the first time a two-dimensional statistical distribution ...
-
Multiscale Approach to the Study of the Electronic Properties of Two Thiophene Curcuminoid Molecules (2016)We studied the electronic and conductance properties of two thiophene-curcuminoid molecules, 2-thphCCM (1) and 3-thphCCM (2), in which the only structural difference is the position of the sulfur atoms in the thiophene ...
-
(Royal Astronomical Society, 2016)By using Adaptive Mesh Refinement cosmological hydrodynamic N-body zoom-in simulations, with the RAMSES code, we studied the mass transport processes on to galactic nuclei from high redshift up to z ∼6. Due to the large ...
-
(American Physical Society, 2018)Weyl semimetals are a new paradigmatic topological phase of matter featuring a gapless spectrum. One of its most distinctive features is the presence of Fermi arc surface states. Here, we report on atomistic simulations ...
-
(Elsevier, 2012)Longest edge (nested) algorithms for triangulation refinement in two dimensions are able to produce hierarchies of quality and nested irregular triangulations as needed both for adaptive finite element methods and for ...
-
(Universidad de Chile, 2021)Caving mining currently represents a low-cost and massive exploitation option. However, its productive and economic attractiveness is affected by some challenges that operations must overcome. Such is the case of the ...
