Spatiotemporal patterns induced by four mechanisms in a tussock sedge model with discrete time and space variables

Admissibility analysis for discrete-time singular systems with time-varying delays by adopting the state-space Takagi-Sugeno fuzzy model

This paper is pertained with the problem of admissibility analysis of uncertain discrete-time nonlinear singular systems by adopting the state-space Takagi-Sugeno fuzzy model with time-delays and norm-bounded parameter uncertainties. Lyapunov Krasovskii functionals are constructed to obtain delay-dependent stability condition in terms of linear matrix inequalities, which is dependent on the low...

Space-in-Time and Time-in-Space Self-Organizing Maps for Exploring Spatiotemporal Patterns

Spatiotemporal data pose serious challenges to analysts in geographic and other domains. Owing to the complexity of the geospatial and temporal components, this kind of data cannot be analyzed by fully automatic methods but require the involvement of the human analyst’s expertise. For a comprehensive analysis, the data need to be considered from two complementary perspectives: (1) as spatial di...

Understanding Spatiotemporal Patterns: Visual Ordering of Space and Time

Deriving patterns and relations from large multivariate and multi-temporal datasets to acquire knowledge about real world processes is not trivial. To understand the content of such datasets current analytical tools do offer interesting solutions, but an integrated approach is lacking. Here we introduce a visual integrated solution that allows one to explore and analyze the data at hand. The ap...
