A new class of space-time models derived from standard dynamic factor models is proposed. The temporal dependence is modeled by latent factors while the spatial dependence is modeled by the factor loadings. Factor analytic arguments are used to help identify temporal components that summarize most of the spatial variation of a given region. The temporal evolution of the factors is described in ...

A master element to be employed as a general spatial rod finite element is presented. This spatially curved and pretwisted element can have variable cross-section and variable curvature change. It may also be resting on an elastic foundation. Also, a finite element formulation for a general earthquake analysis of spatial rods is presented. The theoretical foundation has lead to a general-purpos...

A spatial co-location pattern represents a subset of features whose instances are prevalently located together in geographic space. Although many algorithms mining have been proposed, there still some problems: 1) they miss meaningful patterns (e.g., {Ganoderma_lucidumnew, maple_treedead} and {water_hyacinthnew(increase), algaedead(decrease)}), get the wrong conclusion that two or more increase...

We characterize the shape of spatial externalities in a continuous time and space differential game with transboundary pollution. posit realistic spatiotemporal law motion for pollution (diffusion advection), tackle non-cooperative (and cooperative) games. Precisely, we consider circle partitioned into several states where local authority decides autonomously about its investment, production de...
