2. Mudança Estrutural, Hiato Tecnológico e Capital Humano em um Modelo Norte-Sul de Crescimento com Restrição de Balanço de Pagamentos
Resumo Este artigo tem como objetivo apresentar um modelo macrodinâmico Kaldoriano em que o processo de convergência ou divergência entre o Norte (desenvolvido) e o Sul (em desenvolvimento) é uma função da mudança estrutural e do hiato tecnológico. A participação da indústria na economia do Sul e o hiato tecnológico se tornaram endógenos para ex

5. Towards the Brazilian Space Program Modeling Through the Combination of Stakeholder Theory and System Dynamics Methodology
Abstract: In the last 50 years, Stakeholder (STH) theory has become one of the main instruments of analysis, identification, classification and management of entities in the complex and conflicting corporate environment. In a similar way, System Dynamics (SD) methodology has been used as an instrument for modeling and simulating the dynamics of complex syste

10. 2D upper bound analysis of ECAE through 2θ-dies for a range of channel angles
Equal Channel Angular Extrusion (ECAE), sometimes referred to as Equal Channel Angular Pressing (ECAP), is a Severe Plastic Deformation technique. However the energy-power parameters of ECAE have not been fully addressed in previous known publications. The present article is focused on the punching pressure, accumulated plastic strain, and dead metal zone ge
