Drought Index Mapping at Different Spatial Units

A Real-Time Spatial Index for In-Vehicle Units

We construct a spatial indexing solution for the highly constrained environment of an in-vehicle unit in a distributed vehicle tolling scheme based on satellite navigation (gnss). We show that a purely functional implementation of a high-fanout quadtree is a simple, practical solution that satisfies all the requirements of such a system.

Groundwater Potential Mapping using Index of Entropy and Naïve Bayes Models at Ardabil Plain

Although groundwater resources have long been selected as a safe choice for resolving human water requirements, overexploitation of them, especially at Ardabil plain, has promoted a decrease in the quality and quantity of these resources. One of the significant solutions is to identification of the groundwater potential zones and exploitation of them according to their potentials. The aim of th...

Chemical Organizations at Different Spatial Scales

The dynamics of spatial reaction systems that consists of many molecular species can be difficult to understand. Here we introduce a method that allows to observe the dynamics of a diverse spatial reaction system at different spatial scales. Using chemical organization theory we define for a given spatial location its so called spatial organization, which is the organization generated by the mo...

The influence of circulation weather patterns at different spatial scales on drought variability in the Iberian Peninsula

*Correspondence: Ana C. Russo, Instituto Dom Luiz, Faculdade de Ciências, Universidade de Lisboa, Edifício C8, Piso 3, 1749-016 Lisboa, Portugal e-mail: [email protected] Europe has suffered several extreme weather events which were responsible for considerable ecological and economic losses in the last few decades. In Southern Europe, droughts are one of the most frequent extreme weather events...
