Optimization of Energy Efficiency in Photovoltaic Water Pumping Systems Using Neural Networks

Energy Science &Engineering, EarlyView.
This study investigates an optimal control strategy for a photovoltaic (PV) water pumping system aimed at improving efficiency and autonomy in off‐grid applications. The system uses an induction motor with direct torque control and compares three maximum power point tracking (MPPT) techniques: neural network–based MPPT, Incremental Conductance (IC ...

When Technology Meets Turbulence: The Impact of Digital Transformation and Policy Uncertainty on Audit Opinions

Journal of Corporate Accounting &Finance, EarlyView.
ABSTRACT This study investigates how Corporate Digital Transformation (CDT) influences audit opinions in Chinese A‐share‐listed non‐financial firms from 2011 to 2022, with a focus on the moderating role of Economic Policy Uncertainty (EPU). Results reveal an inverted U‐shaped relationship: moderate levels of CDT enhance audit outcomes through improved ...
