Implementation of the refined zigzag theory in shell elements with large displacements and rotations
(Elsevier, 2014-08)
This work shows a possible implementation of the refined zigzag theory in elements based on Simo’s shell theory. Refined zigzag theory can deal with composite laminate economically, adding only two nodal degrees of freedom, ...
Some properties of deformed q-numbers
(Brazilian Journal of Physics, 2009)
Nonextensive statistical mechanics has been a source of investigation in mathematical structures such as
deformed algebraic structures. In this work, we present some consequences of q-operations on the construction
of ...
POLYLLA: polygonal meshing algorithm based on terminal-edge regions
(Springer, 2022)
This paper presents an algorithm to generate a new kind of polygonal mesh obtained from triangulations. Each polygon is built from a terminal-edge region surrounded by edges that are not the longest-edge of any of the two ...
Fast Most Similar Neighbor (MSN) classifiers for Mixed Data
(Revista Computación y Sistemas; Vol. 14 No.1, 2010-09-30)
Abstract. The k nearest neighbor (k-NN) classifier has been extensively used in Pattern Recognition because of its simplicity and its good performance. However, in large datasets applications, the exhaustive k-NN classifier ...
Fractais no ensino médio
(Universidade Estadual Paulista (Unesp), 2013-11-08)
The purpose of this work is to provide some activities to be developed in the classroom with students from basic education, involving geometric fractals. The characterization of these objects is made through two of its ...
Improved robustness for nearly-incompressible large deformation meshfree simulations on Delaunay tessellations
(Elsevier, 2015)
A displacement-based Galerkin meshfree method for large deformation analysis of nearly-incompressible elastic solids is presented. Nodal discretization of the domain is defined by a Delaunay tessellation (three-node triangles ...
A MINI element over star convex polytopes
(Elsevier, 2020)
In this paper, we extend the concept of MINI element over triangles to star convex arbitrary polytopes. This is achieved by employing the volume averaged nodal projection (VANP) method over polytopes in combination with ...
Simulação numérica do escoamento bifásico de líquido-gás no Interior de um rotor de uma bomba centrífuga radial
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia MecânicaUTFPR, 2017-07-05)
In the petroleum industry it is common the usage of electric submersible pumps as a technique of artificial lift to increase the production or to enable the production in non-natural flowing wells. However, the presence ...
