Given a set B of d-dimensional boxes (i.e., axis-aligned hyperrectangles), a minimum coverage kernel is a subset of B of minimum size covering the same region as B. Computing it is NP-hard, but as for many similar NP-hard ...

We consider the Minimum Coverage Kernel problem: given a set B of d-dimensional boxes, find a subset of B of minimum size covering the same region as B. This problem is NP -hard, but as for many NP -hard problems on graphs, ...

Esta tese é composta por quatro ensaios sobre precificação de ativos e opções. O primeiro ensaio estuda a precificação de opções de índice no contexto de mercados incompletos. Um novo método é fornecido para construir ...

Yellow fever is an arbovirus with high epidemic potential and lethality, where the wild cycle has generated epidemic waves that originate in the Amazon region and reach the rest of Brazil, demanding eco-epidemiological ...

This work proposes a framework to aid the strategic decision making regarding the proper location of fire stations as well as their assignment of vehicles to improve emergency response. We present an iterative simulation ...

The no-tillage system is the predominant model in the agricultural scenario of southern Brazil. Thus, the use of cover crops is significant due to the addition of biomass to protect the soil surface, and contribute to the ...
