In this article, the performance of an inclined north-south axis (INSA) multiple positions sun-tracked V-trough with restricted SCALP THERAPY reflections for photovoltaic applications (MP-VPVs) is investigated theoretically based on the imaging principle of mirrors, solar geometry, vector algebra and three-dimensional radiation transfer.For such a
Effective steel surface defect classification with low computational cost is essential for online quality inspection.The challenge of this task is large intra-class differences and unclear inter-class distances shown in various surface defects.This paper proposes a novel feature extraction method based on Legendre multi-wavelet transform and Auto-E
This paper examines the efficiency of alternative energy equity Exchange-Traded Funds (ETFs) and conventional energy equity ETFs from 2018 to 2020, utilizing a combination of an output-oriented Slack-Based Data Envelopment Analysis (DEA) model and cluster analysis.In the context of an output-oriented DEA model, efficiency is defined as the ability
