Determination of the structural efficiency of quadric and cylindrical surfaces when used as reinforced concrete roof structures
(Journal of Physics: Conference SeriesReino Unido, 2020-12-05)
Modern architecture of civil engineering structures made of reinforced concrete is demanding solutions to problems related to design and construction of roofs shaped as creative forms which require an adequate combination ...

The Karcher mean of three variables and quadric surfaces
(Academic Press Inc Elsevier Science, 2020-10)
The Riemannian or Karcher mean has recently become an important tool for the averaging and study of positive definite matrices. Finding an explicit formula for the Karcher mean is problematic even for 2x2 triples. In this ...
Representação gráfica do ginásio de esportes Belin Carolo: utilização das quádricas e do software maple
(Universidade Tecnológica Federal do ParanáCampo Mourao, 2012)
The Belin Carolo Gymnasium, now part of the structure of UTFPR, was built in late 1970 by

Hilbert space of curved βγ systems on quadric cones
(Int School Advanced Studies, 2008-08-01)
We clarify the structure of the Hilbert space of curved βγ systems defined by a quadratic constraint. The constraint is studied using intrinsic and BRST methods, and their partition functions are shown to agree. The quantum ...

Integrabilidade e dinâmica global de sistema diferenciais polinomiais definidos em R³ com superfícies algébricas invariantes de graus 1 e 2
(Universidade Estadual Paulista (Unesp), 2017-07-05)
Neste trabalho, consideramos aspectos algébricos e dinâmicos de alguns problemas envolvendo superfícies algébricas invariantes em sistemas diferenciais polinomiais definidos em R³. Determinamos o número máximo de planos ...
Proposta de uso de material concreto no ensino de quádricas
(Universidade Estadual Paulista (Unesp), 2022-03-07)
O trabalho consiste em apresentar uma proposta pedagógica para o uso de materiais concretos no ensino de Geometria Analítica nos cursos de ensino superior. Para isso, serão construídas através de uma impressora 3D, modelos ...
Estudo de cônicas e quádricas: construções com o uso do Geogebra
(Universidade Estadual Paulista (Unesp), 2018-08-24)
Este trabalho tem como propósito estudar cônicas e quádricas que podem ser representadas algebricamente por equações do segundo grau em duas e três variáveis, respectivamente. Em particular, a temática de cônicas foi objeto ...
