A Control Strategy With Hybrid Compressor Modeling for Electric Vehicle CO2 Heat Pump Systems
A hybrid PSO‐BP compressor sub‐model is developed and embedded in a MATLAB/Simscape physical model of a transcritical CO2 heat pump system for electric vehicles. Based on this high‐fidelity platform, a phased variable‐PTC cooperative control strategy is proposed and evaluated.

Four Questions for Ethnographers Under Trumpian Authoritarianism
ABSTRACT This article examines evolving challenges and ethical dilemmas facing ethnographers working under intensifying authoritarianism in the United States. Because very little of what the United States is experiencing is new, my work here is primarily curatorial in nature, drawing upon the lessons offered by scholars across disciplines in the United

Imaging Methods for Analyzing Adhesion in Extrusion Coating
ABSTRACT Extrusion coating is a common method to produce materials for the packaging industry. One of the most important properties in extrusion‐coated structures is adhesion between the substrate and the coating. Analyzing adhesion of samples produced by extrusion coating in a standardized way can be challenging, and especially, quantitative data are ...
