Spinorial field and Lyra geometry
(Springer, 2006-10-01)
The Dirac field is studied in a Lyra space-time background by means of the classical Schwinger Variational Principle. We obtain the equations of motion, establish the conservation laws, and get a scale relation relating ...

2D Euclidean distance transform algorithms: a comparative survey
(Association Computing MachineryNew York, 2008-02)
The distance transform (DT) is a general operator forming the basis of many methods in computer vision and geometry, with great potential for practical applications. However, all the optimal algorithms for the computation ...
Geometrias não-Euclidianas no plano e geometria esférica
(Universidade Tecnológica Federal do ParanáCuritibaBrasilLicenciatura em MatemáticaUTFPR, 2018-12-10)
We talk in this work about non-Euclidean geometries, emphasizing in the plane the Poincaré disk model and, in three dimensions, the spherical geometry. In this geometry, we determined some important results, such as the ...
Sobre problemas de máximo e mínimo na Geometria Euclidiana
(Universidade Estadual Paulista (Unesp), 2013-04-11)
Neste trabalho estudamos alguns problemas clássicos envolvendo máximos e míni- mos na Geometria Euclidiana como, por exemplo, o conhecido Problema de Dido e sua relação com a Desigualdade Isoperimétrica

Estudando geometria através de dobraduras
(Universidade Estadual Paulista (Unesp), 2014-03-19)
This work aims to offer an alternative method for teaching Euclidean Geometry for Middle and High School students. This method includes: relaxation techniques, enhancement of concentration, improving motor function and ...
Áreas de polígonos via determinantes
(Universidade Estadual Paulista (Unesp), 2015-08-24)
The aim of this work is to present a study on areas of polygons through their vertex coordinates. We treat the subject using determinants of order 2 and basic Euclidean Geometry
