ICCS 2017 Workshop on AgentBased Simulations, Adaptive Algorithms and Solvers
(2017)This workshop seeks to integrate results from different domains of computer science, computational science, and mathematics. We welcome simulation papers, either hard simulations using finite element or finite difference ... 
An IMEX scheme combined with Richardson extrapolation methods for some reactiondiffusion equations
(20131231)An implicitexplicit (IMEX) method is combined with some socalled Richardson extrapolation (RiEx) methods for the numerical solution of reactiondiffusion equations with pure Neumann boundary conditions. The results are ... 
An IMEX scheme for reactiondiffusion equations: Application for a PEM fuel cell model
(20131231)An implicitexplicit (IMEX) method is developed for the numerical solution of reactiondiffusion equations with pure Neumann boundary conditions. The corresponding method of lines scheme with finite differences is analyzed: ... 
An implicit symplectic solver for highprecision long term integrations of the Solar System
(2022)We present FCIRK16, a 16thorder implicit symplectic integrator for longterm high precision Solar System simulations. Our integrator takes advantage of the nearKeplerian motion of the planets around the Sun by ... 
Influence of boreholeeccentred tools on wireline and loggingwhiledrilling sonic logging measurements
(201306)We describe a numerical study to quantify the influence of tooleccentricity on wireline and loggingwhiledrilling (LWD) sonic logging measurements. Simulations are performed with a hpadaptive Fourier FiniteElement ... 
Intersecting invariant manifolds in spatial restricted threebody problems: Design and optimization of Earthtohalo transfers in the SunEarthMoon scenario
(20121231)This work deals with the design of transfers connecting LEOs with halo orbits around libration points of the EarthMoon CRTBP using impulsive maneuvers. Exploiting the coupled circular restricted threebody problem ... 
Largeoffset Pwave traveltime in layered transversely isotropic media
(20210501)Largeoffset seismic data processing, imaging, and velocity estimation require an accurate traveltime approximation over a wide range of offsets. In layered transversely isotropic media with a vertical symmetry axis, the ... 
Local nonobtuse tetrahedral refinements around an edge
(20131231)In this note we show how to generate and conformly refine nonobtuse tetrahedral meshes locally around and towards an edge so that all dihedral angles of all resulting tetrahedra remain nonobtuse. The proposed technique can ... 
Low cost a posteriori error estimators for an augmented mixed FEM in linear elasticity. Dedicated to Professor Rodolfo Rodríguez on the occasion of his 60th birthday.
(20141231)We consider an augmented mixed finite element method applied to the linear elasticity problem and derive a posteriori error estimators that are simpler and easier to implement than the ones available in the literature. In ... 
Machininginduced characteristics of microstructuresupported LPBFIN718 curved thin walls
(202207)The microstructuresupported design of engineering components is recently gaining attention due to their high strengthtoweight and high stiffnesstoweight properties. The present study investigates the hybrid manufacturing ... 
Magnetotelluric characterization of the alhama de murcia fault (Eastern Betics)  Preliminary results
(20161231)The Lorca Earthquake (11/5/2011, Mw 5.2) stands as the most destructive in Spain over the last 50 years. It was interpreted as having occurred in an intersegment zone of the strikeslip Alhama de Murcia Fault (AMF). Within ... 
Majorant series for the Nbody problem
(20210101)As a followup of a previous work of the authors, this work considers uniform global timerenormalization functions for the gravitationalNbody problem. It improves on the estimates of the radii of convergence obtained ... 
Manufacturing of screw rotors via 5axis doubleflank CNC machining
(202011)We investigate a recently introduced methodology for 5axis flank computer numerically controlled (CNC) machining, called doubleflank milling [1]. We show that screw rotors are well suited for this manufacturing approach ... 
Massive Database Generation for 2.5D Borehole Electromagnetic Measurements using Refined Isogeometric Analysis
