Dirichlet-to-Neumann finite element method for axisymmetric elastostatics in a semi-infinite domain
(CIENCIAS, 2017)
The Dirichlet-to-Neumann finite element method (DtN FEM) has proven to be a powerful numerical approach to solve boundary-value problems formulated in exterior domains. However, its application to elastic semi-infinite ...
Evaluation of an ensemble based data assimilation system over Southern South America: Sensitivity to the use of perturbed boundary conditions
(Servicio Meteorológico Nacional. Gerencia de Investigación Desarrollo y Capacitación. Departamento de Investigación y Desarrollo, 2017)
A coupled FEM-SBFEM approach for soil-structure-interaction analysis using non-matching meshes at the near-field far-field interface
(Elsevier, 2019-06)
Nowadays numerical simulation of soil structure interaction (SSI)is applied to different problems, such as the construction of reliable earthquake-resistant structures. To analyze SSI considering unbounded domains, a ...
Species delimitation with abc and other coalescent-based methods: A test of accuracy with simulations and an empirical example with lizards of the liolaemus darwinii complex (Squamata: Liolaemidae)
(Wiley Blackwell Publishing, Inc, 2012-09)
Species delimitation is a major research focus in evolutionary biology because accurate species boundaries are a prerequisite for the study of speciation. New species delimitation methods (SDMs) can accommodate nonmonophyletic ...
Relationship between the contact force strength and numerical inaccuracies in piecewise-smooth systems
(2021-11-15)
This work studies the different types of behavior and inaccuracies that can occur when contact is not adequately accounted for in a dynamical system with freeplay, as the strength of the contact stiffness increases. The ...
Benchmark problems for numerical treatment of backflow at open boundaries
(Wiley, 2018)
In computational fluid dynamics, incoming velocity at open boundaries, or backflow, often yields unphysical instabilities already for moderate Reynolds numbers. Several treatments to overcome these backflow instabilities ...
Modelagem direta de integrais de domínio usando funções de base radial no contexto do método dos elementos de contorno
(Universidade Federal do Espírito SantoBRMateriais e Processos de Fabricação; Mecânica dos SólidosPrograma de Pós-Graduação em Engenharia MecânicaUFES, 2012-10-19)
A pesquisa envolvida na presente dissertação se baseou no uso de funções de base radial para gerar uma nova formulação integral, que interpola diretamente o termo não homogêneo da equação diferencial de governo, no contexto ...
Music Boundary Detection using Convolutional Neural Networks: A Comparative Analysis of Combined Input Features
The analysis of the structure of musical pieces is a task that remains a challenge for Artificial Intelligence, especially in the field of Deep Learning. It requires prior identification of the structural boundaries of the ...
