This article provides an overview of the development of space–time modeling in Geographic Information Science (GIScience). Distinguished from mathematical modeling of space and time, GIScience approach addresses conceptualization, representation, and database modeling of spatiotemporal constructs to support...

Geostatistical space–time models are used increasingly for addressing environmental problems, such as monitoring acid deposition or global warming, and forecasting precipitation or stream flow. Each discipline approaches the problem of joint space–time modeling from its own perspective, a fact leading to...
future work will explore joint space-time modeling for copepods and NARW. Also, there is an additional SST data source available, HYCOM (Cummings and Smedstad2013) that has wide coverage over the bay, but is recorded at a coarse spatial resolution relative ...
The spacetime autoregressive integrated moving average (STARIMA) model family provides useful tools for modeling spacetime processes that exhibit stationarity (or near stationarity) in space and time. However, a more general method for routine use and efficient computation is needed to model the nonline...

The need is now greater than ever for more accurate space-time channel models with emphasis laid on the question how to integrate the system dependency into the parametric model. In the first part of the thesis, we present a comprehensive analysis on the geometric channel models from a system...
Karen Rosenlof, an atmospheric chemistry expert at the National Oceanic and Atmospheric Administration (NOAA), told Space.com she too was concerned about the effects of the particles from the burning satellites in the atmosphere. Rosenlof has expertise in modeling the effects of geoengineering interve...
The properties and behaviours of architected materials need not be stagnant after fabrication; they can be encoded with a temporal degree of freedom such that they evolve over time. In this Review, we describe the variety of materials architected in both space and time, and their responses to ...
State Space Models (SSMs) have emerged as a potent tool in sequence modeling tasks in recent years. These models approximate continuous systems using a set of basis functions and discretize them to handle input data, making them well-suited for modeling time series data collected at specific freq...
