the rapid change of land use and land cover in the metropolitan area of tehran has influenced the distribution pattern of land surface temperature (lst). in this study, a spatial autocorrelation analysis is adopted to process the spatial-temporal changes of lst and normalized difference vegetation index (ndvi) in tehran during the period of 1987 to 2010. global spatial autocorrelation analysis ...

The objective of this paper is to provide a state of the art review of the application of yield-line analysis to cold-formed steel members, and present a newly developed solution to the stresses that develop in an inclined yield-line. Yield-line analysis in cold-formed steel members is shown to be distinct from traditional yield-line applications. Challenges in the application of yield-line ana...

abstract the quality of soil maps depends upon their ability to show the soils variability. thus, the accuracy of the maps used for crop recommendations is due to the accuracy of soil maps. this study was performed to investigate the amount of soil properties and crop yield spatial variability in s 2 and s3 units of a semi-detailed quantitative suitability map (1:50000 scale) for irrigated whea...

Land-surface topographic attributes can be useful for estimating stable spatial patterns of crop yield caused by spatial variability in soils and water availability. We present spatial analyses of grain yield for three fields of dryland winter wheat in northeastern Colorado using topographic attributes as explanatory variables. Topographic attributes including elevation, slope, aspect, curvatur...

Based on the data about oilseed yield of 87 country units in Shandong province, the paper performed the Moran’s I computerization to analyze the spatial autocorrelation characteristics of the oilseed yield on country level. Results showed that the spatial pattern of the oilseed yield presented the significant agglomeration characteristics, the Moran’s I coefficient of 14 country units was noted...
