Least-perimeter partitions of the disk
(Real Sociedad Matemática Española, 2004)
In this work we study the isoperimetric problem of partitioning a planar disk into n regions of prescribed areas using the least-possible perimeter. We obtain the regularity conditions that must be satisfied by the ...

Analysis of the Parameters of Transfers in Rapid Transit Network Design
(Schloss Dagstuhl--Leibniz-Zentrum fuer Informatik, 2006)
The rapid transit network design problem consists of the location of train alignments and stations in an urban traffic context. The originality of our study is to incorporate into the location model the decisions about ...

More results about spanners in the l1-metric
(Universidad de Sevilla, 2003)
In this work we study more questions about spanners in the l1-metric. Concretely, we will see that adding some Steiner points to a set of sites the metrically complete graph of the new set has a linear number of edges. ...

An Integrated Methodology for the Rapid Transit Network Design
(Springer, 2004)
The Rapid Transit System Network Design Problem consists of two intertwined location problems: the determination of alignments and that of the stations. The underlying space, a network or a region of the plane, mainly ...

Snell’s law in an isoperimetric setting
(American Institute of Physics, 2010)
In this work we focus on the isoperimetric problem in R2 endowed with a piecewise constant density. We will see that the boundary of an isoperimetric solution is not a smooth curve in general, since some corners may ...
