7 This paper shows an innovative implementation of simulated annealing in the 8 context of parallel computing. Details regarding the use of parallel computing 9 through a cluster of processors, as well as the implementation decisions, 10 are provided. Simulated annealing is presented aiming at the generation 11 of stochastic realizations of categorical(More)
Mobile data has allowed us to sense urban dynamics at scales and granularities not known before, helping urban planners to cope with urban growth. A frequently used kind of dataset are Call Detail Records (CDR), used by telecommunication operators for billing purposes. Being an already extracted and processed dataset, it is inexpensive and reliable. A(More)

The Chimera Method developed originally in [1, 19, 20] simplifies the construction 16 of computational meshes about complex geometries. This is achieved by breaking 17 the geometries into components and generating independently a series of different 18 meshes. This enables one a great flexibility on the choice of the type of elements, 19 their orientations(More)
