Polygons with parallel opposite sides
(Springer, 2013-09)
In this paper we consider convex planar polygons with parallel opposite sides. These polygons can be regarded as discretizations of closed convex planar curves by taking tangent lines at samples with pairwise parallel ...
Descripción sintética de objetos en dos dimensiones de acuerdo a su contorno
(2008-10-20)
RESUMEN: En este trabajo se propone una técnica para la descripción sintáctica del contorno de figuras geométricas en dos dimensiones, por medio del análisis de puntos equidistantes sobre el contorno, se aplican criterios ...
Singularities of equidistants and global centre symmetry sets of Lagrangian submanifolds
(SpringerDordrecht, 2014-04)
We study the global centre symmetry set (GCS) of a smooth closed submanifold 'M POT.M'⊂'R POT.N', n≤2m . The GCS includes both the centre symmetry set defined by Janeczko (Geometria Dedicata 60:9–16, 1996) and the Wigner ...

Cartografía matemática y sus aplicaciones
(Universidad de los AndesMatemáticasFacultad de CienciasDepartamento de Matemáticas, 2018)
"El objetivo de la cartografía matemática es valerse de un conjunto de proyecciones, atlases o mapas, para pasar la mayor parte de información geométrica de una superficie curva al plano euclidiano introduciendo la mínima ...
Natural frequencies of thin rectangular plates with partial intermediate supports
(Plapiqui, 2004-12)
In the present study, a methodology to find natural frequencies with arbitrary precision of thin rectangular plates on linear intermediate supports and mixed boundary conditions is presented. This means that the edges are ...
Determination and statistical treatment of short-circuit currents for faults on the lines of networks of 440 kV CESP system
(1995-12-01)
The distribution of short-circuit current is investigated by means of two methods, one direct and the other analytic; both methods consider uniform probability distribution of line faults. In the direct method, the procedure ...

Exatidão das coordenadas topográficas de pontos obtidas a partir de levantamentos geodésicos com receptor GPS L1-L2 no método relativo semiestático
(Universidade Federal de Santa MariaBrasilUFSMCentro de Ciências Rurais, 2011-01-06)
The appearance the satellite of geodesy revolutionized the geodesic survey. However, the
utilization of results obtained in surveys of local topographic planes, using the traditional
methodology, present some operational ...
