    • Affine properties of convex equal-area polygons 

      Craizer, Marcos; Teixeira, Ralph Costa; Silva, Moacyr Alvim Horta Barbosa da
      2012-10
      In this paper we discuss some affine properties of convex equal-area polygons, which are convex polygons such that all triangles formed by three consecutive vertices have the same area. Besides being able to approximate ...

    • Affine skeletons and monge-ampere equations 

      Silva, Moacyr Alvim Horta Barbosa da; Teixeira, Ralph Costa; Velho, Luiz
      2009
      An important question about a. ne skeletons is the existence of differential equations that are related to the 'affine distance' and the 'area distance' (hence to a. ne skeletons) in the same way the Eikonal equation is ...

    • Culling dogs in scenarios of imperfect control: realistic impact on the prevalence of canine visceral leishmaniasis 

      Costa, Danielle N. C. C.; Codeço, Claudia Torres; Silva, Moacyr Alvim Horta Barbosa da; Werneck, Guilherme Loureiro
      2013-08
      Background: Visceral leishmaniasis belongs to the list of neglected tropical diseases and is considered a public health problem worldwide. Spatial correlation between the occurrence of the disease in humans and high rates ...

    • A fast marching method for the area based affine distance 

      Silva, Moacyr Alvim Horta Barbosa da; Teixeira, Ralph Costa; Pesco, Sinesio; Craizer, Marcos
      2008-01
      In a previous paper, it was proved that the area based affine distance of a convex region in the plane satisfies a non-homogeneous Monge-Ampere differential equation. Based on this equation, in this paper we propose a fast ...

    • A linked open data architecture for the historical archives of the Getulio Vargas Foundation 

      Rademaker, Alexandre; Oliveira, Dário Augusto Borges; Paiva, Valeria de; Higuchi, Suemi; Sá, Asla Medeiros; Silva, Moacyr Alvim Horta Barbosa da
      2015-04
      This paper presents an architecture for historical archives maintenance based on Open Linked Data technologies and open source distributed development model and tools. The proposed architecture is being implemented for the ...

    • Polygons with parallel opposite sides 

      Craizer, Marcos; Teixeira, Ralph Costa; Silva, Moacyr Alvim Horta Barbosa da
      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 ...

    • Vector borne diseases on an urban environment: the effects of heterogeneity and human circulation 

      Iggidr, A.; Koiller, Jair; Penna, Maria Lucia Fernandes; Sallet, G.; Silva, Moacyr Alvim Horta Barbosa da; Souza, M. O.
      2017-06
      We study the effect of human circulation and host/vector heterogeneities on the onset of epidemics of arboviruses. From a meta-population dynamics based on the classical Bailey-Dietz model, we derive a multi-group model ...
