Um sistema nuclear é dito subcrítico quando os eventos responsáveis pela remoção dos nêutrons (fuga pelos contornos estruturais do sistema e absorção) acontecem em maior intensidade que os eventos que promovem a produção destas partículas

Autor: R. C. Barros, M. T. Braz-César, Hosein Naderpour, S.M. Khatami

Publikováno v: Journal of Rehabilitation in Civil Engineering, Vol 2, Iss 1, Pp 75-92 (2014)

The objective of this review to be submitted in two independent parts, for steel frames and for RC frames, is to compare their structural performance with respect to the proposed N2-method, and so also of the consequent convenience of using pushover

Numerical Study on Pounding between Two Adjacent Buildings under Earthquake Excitation

Autor: H. Naderpour, R. C. Barros, S. M. Khatami, R. Jankowski

Publikováno v: Shock and Vibration, Vol 2016 (2016)

Seismic excitation, which results in large horizontal relative displacements, may cause collisions between two adjacent structures due to insufficient separation distance between them. Such collisions, known as earthquake-induced structural pounding,

Neutron angular flux reconstruction in slab geometry using multigroup discrete ordinates transport models

Autor: F. T. C. S. Balbina, R. C. Barros, H. Alves Filho

Publikováno v: Brazilian Journal of Radiation Sciences. 8:01-18

In this article, we present an application of the coarse-mesh Deterministic Spectral Method (SDM) to generate multigroup angular fluxes in one-dimensional spatial domains using the neutron transport stationary equation, in the formulation of discrete

This manuscript presents a comparison of noise properties exhibited by two stochastic binary models for: (i) a self-repressing gene; (ii) a repressed or activated externally regulating one. The stochastic models describe the dynamics of probability d
