Vor 3 Tagen · Instant-runoff voting (IRV), also known as ranked-choice voting or the alternative vote (AV), combines ranked voting (in which voters rank candidates rather than choosing only a single preferred candidate) together with a system for choosing winners from these rankings by repeatedly eliminating the candidate with the fewest first ...
Vor einem Tag · Rainwater runoff, with its high concentration of pollutants, is a major contributor to water pollution. When the runoff enters our waterways, it can contaminate rivers, lakes, and oceans, posing a threat to aquatic ecosystems and the organisms that depend on them. The pollutants can disrupt the natural balance of these ecosystems ...
Vor 19 Stunden · In the initial task, we only use one model to predict runoff, RR-TiDE outperformed both Transformer and LSTM-based models across all metrics for 7-day runoff predictions. In the second task, RR-TiDE achieved a median NSE of 0.82 in 1-day runoff forecasting in 51 watersheds, demonstrating a strong predictive capability. To test the effects of ...
Vor 19 Stunden · Initially, we partitioned runoff response change (RRC) into multiple components associated with climate and catchment properties, and examined the spatial patterns and smoothness indicated by the Moran’s Index of RRC across the contiguous United States (CONUS). Subsequently, we employed a machine learning model to predict RRC using catchment attribute predictors encompassing climate ...
Vor 4 Tagen · This study preliminarily proves the effectiveness of combining the cyclical characteristics of NBEATSx and wavelet transforms and creatively proposes a new deep learning model integrating LSTM and RF, providing new insights for further considering multi-scale features of complex runoff time series, thereby enhancing runoff prediction ...
Vor 2 Tagen · In winner-take-all or plurality systems – such as first-past-the-post (FPTP), instant-runoff voting (IRV), and block voting – one party or voting bloc can take all seats in a district.
Vor 11 Stunden · Jon Alterman, "The Impacts of Raisi's Death," CSIS, May 20, 2024. Masoud Pezeshkian recently won the runoff election to replace Iran's late president, Ebrahim Raisi. This week, Leah Hickert speaks with Jon Alterman, director of the Middle East Program at CSIS, about Pezeshkian and the election's impact on regional politics.
