The spatial panel data model is a standard tool for analyzing data with both spatial correlation and dynamic dependences among economic units. Conventional estimation methods rely on the key assumption that the spatial weight matrix is strictly exogenous, which would likely be violated in some empirical applications where spatial weights are determined by economic factors. This paper studies th...

As a crucial component in intelligent transportation systems, traffic flow prediction has recently attracted widespread research interest the field of artificial intelligence (AI) with increasing availability massive mobility data. Its key challenge lies how to integrate diverse factors (such as temporal rules and spatial dependencies) infer evolution trend flow. To address this problem, we pro...

to evaluate the effect of crop rotation on spatial dynamic of fumaria vaillantti and polygonum aviculare a study was conducted at the three farms with different rotation in the astan ghods razavi filed that located at 10 kilometers southeast of mashhad, iran. the rotations were alfalfa- fallow- wheat, canola- fallow- wheat, and wheat- fallow- wheat. at the crosses of 7×7 m quadrangular grids ne...

For the last two decades, two related approaches have been studied independently in conjunction with limitations of image sensors. The one is to reconstruct a high-resolution (HR) image from multiple low-resolution (LR) observations suffering from various degradations such as blur, geometric deformation, aliasing, noise, spatial sampling and so on. The other one is to reconstruct a high dynamic...
