Detecção de Conglomerados Espaciais com Geometria Arbitrária

This paper evaluates a variation of the spatial scan statistic that aggregates the neighbor structure into the cluster growing process. This proposal allows the detection of arbitrarily shaped clusters and it is an alternative to the original circular shaped scan geometry. The spatial scan statistic is widely used and presents consistent results with real and simulated data sets. In order to te...

Reconstrução da Geometria de Itinerários de ônibus a partir de Descrições Textuais

Bus routes are fundamental information for users when planning their way through the city. Reading and understanding the routes, which are usually presented as tables with street names, is a difficult task. In this work, we present a method aimed at retrieving the route’s geometry based on its table and the city’s road network, which allows viewing the route on a map. Using the proposed method,...

Appunti di geometria combinatoria

Dato un insieme A di n elementi, si chiamano disposizioni di classe k i suoi sottoinsiemi ordinati di k elementi. Se si ammette che gli elementi possano anche ripetersi si parla di disposizioni con ripetizione, altrimenti di disposizioni semplici. Le disposizioni semplici aventi n = k si chiamano permutazioni semplici. Si chiama permutazione con ripetizione una permutazione di n elementi non tu...

Trefftz–Herrera Method

The author’s algebraic theory of boundary value problems has permitted systematizing Trefftz method and expanding its scope. The concept of TH-completeness has played a key role for such developments. This paper is devoted to revise the present state of these matters. Starting from the basic concepts of the algebraic theory, Green–Herrera formulas are presented and Localized Adjoint Method (LAM...
