Desarrollo de conocimientos matemáticos informales a través de resoluciones de problemas aritméticos verbales en primer curso de educación primaria
… with a categorization from previous studies. Direct modeling strategies have been analyzed according to the representation of the quantities and the mode to carry out counting. This circumstance coupled with the freedom given in the selection and use of materials, has led to the detection of …

Comprehensive Electromagnetic Approach for Modeling of on-Chip Power Grid Switching
… model for the on-chip power grid directly from the physical geometry in chip design. More specifically, the primitive system of Maxwell's equations for the rotation of the electric and magnetic fields is discretized over a finite-difference grid that encompasses the power grid. The …

Dual mappings and phase transitions in a short-range random valence bond theory
… The VBC/QSL phase transition is investigated by direct modeling of the J-V version of the SRRVB and measuring various correlation functions.

Vortex Methods for Fluid Simulation in Computer Graphics
… the computer graphics community for simple and direct modeling of complex flow phenomena such as turbulence. However, vortex methods have not been developed yet to the level of other techniques for fluid simulation in computer graphics. In this work we present a novel simulation framework to …

Optimizing paint blocking in an automobile assembly line : an application of specialized TSP's
… cars and windows of 75 slots per car in either direction, direct modeling using the strongest known ... formulation yields an integer program with up to 200,000 constraints and 14,000,000 variables. Reduced formulations. We exploit special problem structure to solve the LP relaxation of this …

Development of constitutive models for thin thermoelastic interphase in composite materials
… small thickness of the interphase, accurately modeling its behavior and capturing variations across and within it presents a significant computational challenge. To address these difficulties, the physical interphase in the three-phase problem is replaced with an equivalent zero-thickness …

Lattice-Boltzmann modeling of multiphase flow through rough heterogeneously wet fractures
… from laboratory experiments is unpractical, a 3D direct simulation approach via the lattice Boltzmann method was selected. This was chosen based on its rigorous kinetic derivation, its ability to simulate immiscible displacement, and its versatile boundary conditions. To study the effects of …
