Review on Processing Control Strategy for Electrochemical Additive Manufacturing
MetalMat, EarlyView.This review systematically summarizes recent progress in processing control strategies for ECAM, with three key regulation dimensions: current monitoring and closed‐loop control, temperature regulation, and electrolyte flow/nozzle design. The roles of these parameters in governing electrochemical kinetics, mass transport, deposition stability, and ...

Energy Optimization Models for the Locomotive Assignment Problem
Networks, EarlyView.ABSTRACT Reducing energy consumption is a key objective in transportation. Using detailed infrastructure data, this study introduces the Green Locomotive Assignment Problem (GLAP) to minimize energy consumption in railway operations by efficiently assigning locomotives to pre‐scheduled trains.

Elevator dynamic monitoring and early warning system based on machine learning algorithm
IET Networks, EarlyView., 2022 In order to monitor and warn the elevator dynamics, in this work, the machine learning algorithm is introduced, and the particle swarm algorithm is used to perfect the model. The model is optimised, and the experimental comparison shows that the optimisation of the model parameters can further improve the accuracy of the elevator load prediction. Then,

Pest Management Science, EarlyView.Optimizing PWM performance requires not only appropriate duty cycle selection, but also careful choice of adjuvant formulation tailored to each nozzle type. Drift control agents increased droplet size and reduced fine droplets, mitigating PWM‐induced variability. Decreasing the duty cycle consistently narrowed the spray angle.
