Carbon emission reduction is a challenge and an opportunity for all countries in the world. In this paper, Delphi method applied to screen indicators affecting carbon emission, first second level weighting are derived according Spearman, heat map, entropy method, building life cycle indicator system established. Then, taking Jiangsu Province as example, TOPSIS was used comprehensively evaluate ...

Recently, wind power plants that generate energy with electricity are attracting a lot of attention thanks to their smaller installation area and cheaper generation costs. In generation, it is important predict the amount generated because system would be unstable due uncertainty in supply. However, difficult accurately varies several causes, such as speed, direction, temperature, etc. this stu...

Kredi kartı aracılığıyla hızlı ve kolay satın alma işlemleri sahtecilik işlemlerinin artmasına neden olmuştur. Son yıllarda makine öğrenmesi yöntemlerinin kullanımı tespiti işlemlerinde önemli bir pay oluşturmuştur. Sahtecilik karşılaşılan yaygın problemlerden birisi veri kümelerinin dengesiz olmasıdır. Dengesizlik problemi için kullanılan yeniden örnekleme metotları kullanıldıkları aşamalar ba...

Journal: :Remote Sensing 2022

With the development of multisource satellite platforms and deepening remote sensing applications, growing demand for high-spatial resolution high-temporal images has aroused extensive interest in spatiotemporal fusion research. However, reducing uncertainty results caused by sensor inconsistencies input data preprocessing is one challenges algorithms. Here, we propose a novel bias correction m...
