Four experiments investigated observers' judgments of rigidity for different types of optical motion. The depicted structural deformations were of two types: (1) those with nonparallel image trajectories that are detectable from the first-order spatiotemporal relations between pairs of views; and (2) those with parallel image trajectories that can only be detected from higher order relations am...

Spatiotemporal data mining is an emerging area of research. Applications for mining different kinds of spatiotemporal patterns and trends are being developed by researchers in various domains. However, there is a need for underlying architecture framework for these applications to provide reusability of analysis and design. This research paper addresses such a requirement by adopting conceptual...

Drought is one of the most devastating natural hazards causing considerable losses in all climatic zones world. It complex and least understood at same time because its spatially heterogeneous temporally variable character. Spatially dense uniformly distributed ground-based meteorological data are needed for proper spatial temporal drought analysis. In practice, such lacking general due either ...

O objetivo deste trabalho foi estudar o tempo temporal e espacial da murcha do Fusarium em plantas de pimenta-do-reino. Como foram avaliadas a cada dois meses durante um ano nove áreas plantadas com pimenta reino localizado na região norte estado Espírito Santo, Brasil. Em área 500 campo preta, faça uma localização planta avalie incidência fusões. A partir dessas práticas, usado mapa acumulado ...

We investigate spatiotemporal dynamics of a semi-ratio-dependent predator-prey system with reaction-diffusion and zero-flux boundary. We obtain the conditions for Hopf, Turing, and wave bifurcations of the system in a spatial domain by making use of the linear stability analysis and the bifurcation analysis. In addition, for an initial condition which is a small amplitude random perturbation ar...
