Abstract:
... The Iowa caucuses are the inaugural event of the American presidential nomination process. When the state Democratic Party failed to report the 2020 caucus results in a timely manner, researchers began to assess how party and press officials co-constructed the events. This research presents an in-depth case of the Iowa state and local Democratic Party’s public communication response regarding an e ...

Abstract:
... To avert the degradation information island brought by a single model for state estimation of lithium-ion batteries (LIBs), multi-model integration is well worth being extended for health evaluation. A cloud-edge collaboration strategy that integrates multi-model adaptation and machine learning is proposed for battery capacity prediction in lifespan. In this respect, multiple individual algorithms ...

Abstract:
... Watershed models are robust tools that inform management and policy in a variety of sectors, but these models are often neglected through time due to economic or technical constraints. Additionally, they are not readily accessible tools for key decision makers. Conversely, machine learning models are robust alternatives to common hydrologic modeling frameworks. The random forest algorithm specific ...
