Summary: This research uses drones and MATLAB (R) image analysis to detect failures in solar modules and evaluate their health. The use of drones significantly improves inspection efficiency, and a new box filtering method enhances the 3D image for more convenient and accurate health checks. The study also shows that the 3D image recognition technology provides better defect diagnosis capability and serves as a quantitative and qualitative indicator.

Summary: This study provides a brief review of gasification technology and identifies the best blowing agents and gasification methods for improved efficiency and environmental safety. A mathematical model of a steam-oxygen gasifier was developed, considering the impact of input parameters on combustion heat. The research presents methods to enhance the combustion heat of syngas and optimal ratios of blowing agents and solid fuel for gasification, as well as output parameters of the produced generator gas.

Summary: This paper presents an experimental investigation on the convective heat transfer around circular cylinders installed one after another using gradient heatmetry and particle image velocimetry. The study shows that the length of re-circulation bubble and vortex formation features have an influence on the flow pattern and characteristics. The results are found to be in good agreement with previous experimental and numerical data.
