When the normalized chromatographic data were subjected to similarity index calculations, definite seasonal variation was observed with the most matches occurring in adjacent months and the most mismatches occurring in distant months. This method appears to have value in determining the chromatographic ...
In this research, twenty-four (24) machine learning models were constructed to predict the Standardized Precipitation Evapotranspiration Index (SPEI) in various timescales, including 1-, 3-, 6-, and 12-month periods. The methodology, as illustrated in Fig. 2, encompassed the subsequent procedural...
Redundancy analysis indicated that water temperature, total nitrogen, total phosphorus, ammonia nitrogen, Nitrate nitrogen, permanganate index and Secchi depth were the main environmental factors that influencing the functional groups. Although the filamentous cyanobacteria were seasonally different in terms of...
