Se presenta un análisis crítico sobre las metodologías y enfoques de modelación utilizados actualmente en la ciencia de los transportes. Se señalan inconsistencias que surgen de la confrontación entre la práctica, las herramientas de modelaje utilizadas y los desarrollos teóricos en varias disciplinas. Se plantean cuatro ejes de análisis: la modela...

En esta investigación se realizó un análisis de la evolución de la confiabilidad de ductos enterrados que transportan hidrocarburos basándose en cinco distribuciones de velocidad de crecimiento de defectos. Las distribuciones de velocidad de crecimiento utilizadas fueron: el valor único de velocidad de corrosión recomendado por la Asociación Nacion...

The development of this paper is based on the study of cold water storage in air conditioning systems. To offset power consumption off-peak, as a tool to increase energy efficiency claim and reduce the cost of electricity in tropical hotels. To do this we proceed to estimate the thermal load profile Jagua by TRNSYS software, system design and testi...

Neste artigo, apresentamos os resultados de uma pesquisa sobre a ressignificação da Série de Taylor em uma situação de modelação do movimento (SM-M). De acordo com a perspectiva epistemológica, o discurso matemático escolar habitual não leva em consideração o aspecto funcional da Série de Taylor. À luz dos trabalhos de Newton, esta perspectiva dest...

RESUMEN Se aplica la modelación numérica de un edificio de mampostería cerámica cocida de fines del siglo XIX en la zona de mayor riesgo sísmico de Argentina mediante el método de los elementos finitos. Para la verificación estructural se formula un modelo no lineal, utilizando elementos tipo shell que simulan el comportamiento no lineal de la mamp...

This paper shows the development of a tool for energetic improve of plastic pipes extrusion processes by heat transference processes transients using the Wolfram Mathematica7 software. With this tool may take decisions quickly to keep an optimized process in function of the material properties used to increasing the productions and to reduce the co...

One of the most fundamental problems formulated to machine learning is the development of habits and abilities in complex systems modeling. At the present paper a system named Generator of Problems Hypermedia is described and developed. This software system allows automating the process of optimization problem construction and automatic generation ...

The research try to analyse the Corporate Social Responsibility (CSR) based on a model of Compensatory Fuzzy Logic (CFL) in companies that apply the Entrepreneurial Improvement (EI). The CFL allows modelling the knowledge of the predicates correlated to the CSR concept by looking for the continuous refinement of the Management System in terms of th...
