Gradient flows, second-order gradient systems and convexity
(Society for Industrial and Applied Mathematics Publications, 2018)
We disclose an interesting connection between the gradient flow of a C 2 - smooth function ψ and evanescent orbits of the second order gradient system defined by the square-norm of ∇ψ, under adequate convexity assumption. ...

Gradients of histogenesis in the ependymal lining of the third ventricle in the Rabbit
Tritiated thymidine autoradiography was used to analyze the site, time of origin, and developmental gradients of the specialized lining of the ependymal surface of the third ventricle. Cells destined to form the ependyma ...
Nonmonotone spectral projected gradient methods on convex sets

Simulador de escoamento multifásico em poços de petróleo (SEMPP)
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia do PetróleoPesquisa e Desenvolvimento em Ciência e Engenharia de Petróleo, 2013-02-07)
The multiphase flow occurrence in the oil and gas industry is common throughout fluid path, production, transportation and refining. The multiphase flow is defined as flow simultaneously composed of two or more phases with ...
Gradient systems on coupled cell networks
functions, that is, functions whose gradient is an admissible vector field. The schematic representation of a gradient network dynamical system is of an undirected cell graph, and we use tools from graph theory to deduce ...
