In this study, eco-friendly deep eutectic solvents (DESs) were used as extracting agents for the first time in extraction of pectins from mango peel. Two novel green including betaine-citric acid (Bet-CA) and choline chloride-malic (ChCl-MaA) screened, conditions further optimized by full factor design experimental along with RSM. addition, ultrasound treatment also had an influence on yield, structural physicochemical properties extracted pectins. DES-extracted significantly higher larger...

Infrared imaging technology, as an effective on-site condition monitoring means of equipment, is widely used in the maintenance task insulators. Accurate segmentation insulators infrared images great significance for temperature data acquisition and fault diagnosis. The presence multiple electrical devices image substantially increases difficulty insulator instance segmentation. Moreover, methods based on pixel-level sample annotation consume a lot time resources. Therefore, box-supervised...

Fructose is a vital ketose in the production of 5-hydroxymethylfurfural platform molecules. Herein, Zr-doped hexagonal mesoporous silica was prepared over situ co-assembly (Zr-x-HMS, x mole ratio Si to Zr, = 20, 50) and post-impregnation (Zr-Imx-HMS, 50, 100) processes regulate its catalytic performance against isomerization glucose fructose ethanol. The process did not significantly change original pore structure morphology HMS, Zr-Im50-HMS with medium Zr loading possessed most Lewis acid...

Aiming at the problems of inaccurate positioning, low recognition efficiency, and difficult segmentation insulator image in complex background, an infrared algorithm based on dynamic mask box annotation is proposed. In conditional convolution instance network framework, single-shot high-performance box-supervised methods are introduced, mask-level loss used to replace pixel-level loss. By marking insulators with a rectangular frame, can realize overall string. The experimental results show...

Abstract As the core equipment of transmission and distribution hubs, operational status gas‐insulated switchgear (GIS) is closely linked to safety power system. Recently, X‐ray digital imaging technology has been extensively used in GIS fault detection. However, image blurred, which not conducive detection tiny defects. Thus, a super‐resolution method for images based on multi‐scale context transformers proposed this study, namely MCTSR. Firstly, second‐order degradation model introduced...

Breast cancer prediction is crucial in identifying women who may be at risk for developing the disease. By doing prediction, doctors can make rapid diagnosis. Additionally, breast also help guide research efforts and inform public health policies aimed reducing incidence mortality of cancer. SVM (Support Vector Machine)is a classic method machine learning, Random Forest widely used but they all have some shortcomings. dont high accuracy. So RF-SVM(Random Forest) chosen to do prediction. The...
