Connected Components in Undirected Set--Based Graphs. Applications in Object--Oriented Model Manipulation
Ernesto Kofman, Denise Marzorati, Joaquín Fernández
This work introduces a novel algorithm for finding the connected components of a graph where the vertices and edges are grouped into sets defining a Set--Based Graph. The algorithm…
retQSS: A Novel Methodology for Efficient Modeling and Simulation of Particle Systems in Reticulated Geometries
Lucio Santi, Joaquín Fernández, Ernesto Kofman +1
This work presents retQSS, a novel methodology for efficient modeling and simulation of particle systems in reticulated meshed geometries. On the simulation side, retQSS profits fr…
Magnetostriction Reveals Orthorhombic Distortion in Tetrahedral Gd-compounds
Diana Betancourth, Victor F. Correa, Jorge I. Facio +5
We report detailed thermal expansion and magnetostriction experiments on GdCoIn and GdRhIn single crystal samples that show a sudden change in the dilation at a field B$^\a…
