Abstract:
... Capacity estimation is of great significance to help assess the performance degradation of lithium-ion batteries, so as to take actions to extend their lifetime. Traditional capacity estimation methods for Lithium-ion batteries are usually based on individual model-based or data-driven prognostic approaches. However, no single prognostic method performs appropriately for all possible situations as ...

Abstract:
... In this study, we assess the extent to which attending a candidate rally was associated with distrust of democratic institutions, epistemic rigidity, attribution of malevolent intentions to the political outgroup, and acceptance of political violence. Surveys (N = 251) were distributed at rallies the night before and day of the 2016 Iowa Caucuses. Results suggest that attendees of rallies for Bern ...

Abstract:
... In this note, we propose a local maximum likelihood estimator for spatially‐dependent distributions. Our estimator adopts the Poisson regression approach for density ratio models and incorporates spatial smoothing via local regression. We also present a method of smoothing parameter selection. We illustrate this easy‐to‐implement estimator with an application to the estimation of corn yield distri ...

Good agreement is observed between the 3-D model predictions and results of dam-break experiments performed in the laboratory. The 3-D model is then applied to predict flood-wave propagation induced by the sudden failure of two flood-protect ...

Abstract:
... Walleye Sander vitreus Mitchill have been progressively raised in hatcheries to larger sizes under the paradigm that larger stocked fish have higher survival. However, extended time in hatcheries may result in domestication, with stocked individuals lacking behaviours that promote survival. The objective of this study was to evaluate behaviour and survival of wild versus stocked fingerling (>200 m ...

Abstract:
... Fractured till is often represented as an equivalent porous medium (EPM) in groundwater models. Knowledge of the representative elementary volume (REV) is necessary for proper application of an EPM model. While REV estimation and hydraulic conductivity tensor determinations are common in fractured rock studies, they are rarely applied to materials with a permeable matrix such as fractured till. Th ...

Abstract:
... Current estimations of sediment transport at the watershed scale are limited by the difficulty of accurately simulating the sediment transfer along the main stem.
