13. Stability of Semidiscrete Formulations For Advective-Diffusive-Reactive Transport Problems / Estabilidade temporal de formulações semi-discretas para problemas de transporte convectivo-difusivo-reativo
This work deals with the stability analysis of the fully discrete transport problem obtained using a stable finite element method in space and the generalized trapeizoidal family of methods in time. Depeding on the range of parameters the Galerkin and the Streamline Upwind Petrov-Galerkin Methods are introduced. We evaluate the accuracy and stability propert

14. AnÃlise paramÃtrica de um reator anelar pulsado
A new pulsed reactor concept VICHFPR (Very Intense High Continuous Flux Pulsed Reactor) was presented in 1997 as a possible extension of IBR-2 periodically pulsed Russian reactor. The concept has an annular core which is traversed by a reactivity modulator responsible for generating a rotating neutron pulse. While the most part of the core operates under sub

15. Evolutionary behavior of dispersal process of produced water resultant from offshore : numerical treatment and computational / Comportamento evolutivo de descarga de agua de produção decorrente de atividade offshore : tratamento numerico e simulação computacional
In this work we study the evolutionary behavior of dispersal process of produced water resultant from off-shore activities, using a system of the classic partial differen-tial equations to mo deI both a circulation map as well as diffusion and advection in a three-dimensional domain. An existence and uniqueness result is obtained in the studied case, where f

16. Mathematical modeling and computational simulation of the presence of toxic impactant materials in cases of populational dynamics with inter-and intra-specific competition / Modelagem matematica e simulação computacional da presença de materiais impactantes toxicos em casos de dinamica populacional com competição inter e intra-especifica
A proposta deste trabalho é criar um modelo para descrever computacionalmente o convívio entre duas espécies competidoras com características de migração na presença de um material impactante tóxico. As equações a serem utilizadas deverão incluir os fenômenos de dispersão populacional, processos migratórios, dinâmicas populacionais densidade-d
