Article Synopsis
  • Photovoltaic (PV) panels are a key area of research in green energy, particularly for estimating their parameters for health monitoring and fault diagnosis.
  • A new method using an artificial neural network (ANN) and particle swarm optimization (PSO) has been developed to estimate these parameters more accurately by analyzing dynamic current and voltage responses.
  • Simulations demonstrate that this new approach can improve estimation accuracy by up to 3.5% and increases the speed of convergence compared to traditional methods.

Photovoltaic (PV) panels have been widely used as one of the solutions for green energy sources. Performance monitoring, fault diagnosis, and Control of Operation at Maximum Power Point (MPP) of PV panels became one of the popular research topics in the past. Model parameters could reflect the health conditions of a PV panel, and model parameter estimation can be applied to PV panel fault diagnosis.

Developmental coordination disorder (DCD) is a type of motor learning difficulty that affects five to six percent of school-aged children, which may have a negative impact on the life of the sufferers. Timely and objective diagnosis of DCD are important for the success of the intervention. The present evaluation methods of DCD rely heavily on the observational analysis of occupational therapists and physiotherapists, who score the performance when children conduct some designed tasks.

Eye tracking technology has become increasingly important for psychological analysis, medical diagnosis, driver assistance systems, and many other applications. Various gaze-tracking models have been established by previous researchers. However, there is currently no near-eye display system with accurate gaze-tracking performance and a convenient user experience.
