1数学教学中的开放式教学——创造一种课堂数学文化显示文摘数学教学中需要对开放式教学进行合作研究.在日本的开放式教学中,数学问题被选择是用来说明一个问题的多种解法或多个正确答案.数学教学要实现一种全新的课堂数学文化,这种教学形式的特点是:问题开放、解决问题的过程开放、构建问题开放、评价开放,使学生能自由地思考,发展学生的思维能力.桥本吉彦 Jerry Becker 孙连举 于卓 2002数学教育学报2002,11,1:14
2Mapping summer soybean and corn with remote sensing on Google Earth Engine cloud computing in Parana state – Brazil显示文摘Brazilian farming influences directly the worldwide economy.Thus,fast and reliable information on areas sown with the main crops is essential for planning logistics and public or private commodity market policies.Recent farming practices have embraced remote sensing to provide fast and reliable information on commodity dynamics.Medium-to-low resolution free orbital images,such as those from Landsat 8 and Sentinel 2,have been used for crop mapping;however,satellite image processing requires high computing power,especially when monitoring vast areas.Therefore,cloud data processing has been the only feasible option to deal with a large amount of orbital data and its processing and analysis.Thus,our goal was to develop a method to map the two main crops(soybeans and corn)in Paraná,one of the major Brazilian state producers.Landsat-8,Sentinel-2,SRTM+,and field data from 2016 to 2018 were used with the Simple Non-Iterative Clustering segmentation method and the Continuous Naive Bayes classifier,to identify cropped areas.A minimum global accuracy of 90%was found for both crops.Comparison with field data showed correlations of 0.96 and agreement coefficients no lower than 0.86.This ensures mapping quality when using Sentinel and/or Landsat imagery on the GEE platform.Alex Paludo Willyan Ronaldo Becker Jonathan Richetti Laíza Cavalcante De Albuquerque Silva Jerry Adriani Johann 2020International Journal of Digital Earth2020,13,12:2
3炼油厂中的工业无线技术显示文摘石油管道和炼油厂的地理位置给运营商带来了挑战:如何保持系统的高效运营和有效维护。在美国,大部分的炼油厂都位于墨西哥湾沿岸,设备需要承受高温、高湿度、暴风雨和飓风。Jeff Becker Jerry Stanek 2010自动化博览2010,27,7:0
