The rational function model (RFM) utilized for high resolution satellite imagery (HRSI) provides a transformation from image to object space coordinates in a geographic reference system. Compared with the rigorous model based on the collinearity condition equation or the affine model, the RFM with 80 coefficients would be over parameterized. That would result in an ill-conditioned normal equati...

Objective: Ceftiofur, a third-generation cephalosporin, is used as a usual antimicrobial drug in veterinary medicine. Positive efficiency of ceftiofur for treatment of retained fetal membrane (RFM) and acute puerperal metritis has been previously reported. Thus, this study was conducted to evaluate the efficiency of ceftiofur hydrochloride (CH) in prevention of uterine postpart...

This study aimed at providing a systematic method to analyze the characteristics of customers’ purchasing behavior in order to improve the performance of customer relationship management system. For this purpose, the improved model of LRFM (including Length, Recency, Frequency, and Monetary indices) was utilized which is now a more common model than the basic RFM model apt for analyzing the cus...

Ridge-furrow film mulching has been proven to be an effective water-saving and yield-improving planting pattern in arid semi-arid regions. Drought is the main factor limiting local agricultural production Loess Plateau of China. In this study, we tried select a suitable ridge-furrow system improve situation. A two-year field experiment summer maize (Zea mays L.) during growing seasons 2017 2018...

The initial dry density has a significant effect on the mechanical behavior of rockfill material (RFM). size effects minimum/maximum (referred to as density, ρ d ) RFM still need further study. To investigate relationship between and M , series surface vibration compaction tests DEM simulations are performed samples with different maximum particle sizes . Both physical numerical results exhibit...

Numerous firms accumulate large quantities of data or transactions after importing information systems and services, which leads to troubles with procedure. Firms also have demands find customers’ from datasets understand how develop marketing strategies accurately adjust their operational methods. Therefore, this study proposed customer ranking combined Big Data process based on the RFM model ...

Improving farming practices of soil and water conservation has profound effects on the yield of wheat (Triticum aestivum L.) in dryland farming regions of the Loess Plateau in China. Mulching has proven to be an effective practice to increase crop yield, and possibly contribute to replenishing groundwater. This evaluation study collected and analyzed the data of 1849 observations published in 3...
