A tool for model conversion between simulators of grid computing
(2015-01-01)
High performance computing systems usually have a high usage cost, even with the use of shared systems, such as grids and clouds. To reduce such costs it is necessary to optimize system's utilization through performance ...
Global-local HROM for non-linear thermal problems with irreversible changes of material states
(Elsevier France-editions Scientifiques Medicales Elsevier, 2018-07)
Highly concentrated moving nonlinearities are extremely difficult to solve numerically. The Selective Laser Melting Additive Manufacturing process is a problem of this kind. A material global-local scheme is proposed, which ...
Industrial high pressure ethylene polymerization initiated by peroxide mixtures: A reduced mathematical model for parameter adjustment
(John Wiley & Sons Inc, 2001-05)
We present a method for the adjustment of parameters in the mathematical modeling of industrial tubular reactors for high pressure polymerization of ethylene. We propose a reduced mathematical model for these reactors that ...
Predictive Control of the mineral particle size with kernel-reduced volterra models in a balls mill grinding circuit
(Institute of Electrical and Electronics Engineers Inc., 2015-06)
We report the results of the application of the Model-based Predictive Control (MPC) algorithm for a 3×3 MIMO balls mill grinding system by using computational simulation and Monte Carlo data generation. For this purpose, ...
An enhanced substructure coupling technique for dynamic re-analyses: Application to simulation-based problems
(2016)
This work presents the implementation of an enhanced substructure coupling technique in the context of complex simulation-based problems. Attention is focused to problems requiring a large number of dynamic re-analyses of ...
The Evolution of Inventory Management in Manufacturing and Services Companies
(Centro de Investigaciones Comerciales e Iniciativas Académicas de la Facultad de Administración de Empresas. Forum Empresarial. Vol.5 Num.2, 2010)
Global–Local ROM for the solution of parabolic problems with highly concentrated moving sources
(Elsevier Science Sa, 2017-11)
Problems characterised by steep moving gradients are challenging for any numerical technique and even more for the successful formulation of Reduced Order Models (ROMs). The aim of this work is to study the numerical ...
Improvement proposal applying standardized work and 5's to reduce the rate of returned orders of a poultry company under the PDCA cycle
(Universidad de LimaPE, 2023)
Over the last few years, the poultry sector has positioned itself advantageously in the Peruvian market since it contributes 56% of the animal protein consumption demanded by the population. This represents annual sales ...
Joint reconfiguration of feeders and allocation of capacitor banks in radial distribution systems considering voltage-dependent models
(Elsevier B.V., 2019-05-01)
This paper presents a study about operation planning for radial distribution systems using a mixed-integer second-order cone programming formulation. The proposal consists of a complete model for solving the problems of ...
