“…The majority of the image processing operations are included in the OpenMV vision module that was used in this project. The core algorithmic function in this project, find blobs [3] , locates and returns all of the color blocks in the image. All of the returned objects will be merged by this function.…”

The system uses the OpenMV algorithm module combined with the k-means framework through the Euclidean distance formula to facilitate the automation of logistics sorting, which identifies the color of logistics parcels in the LAB color space. It sends the identified color information to the motion drive module, which sorts and transports the logistics parcels to the designated storage area. The fusion of algorithms allows the system to identify colors and transportation accurately.

“…With reference to the literature, 8 40 g of cotton stalk bark fibers was soaked in a mixed solution including 20% sodium sulfide, 2% anthraquinone, 2% sodium silicate, and different concentrations of caustic soda (5, 10, or 15%) for 0.5 h at 150 C. The degummed cotton stalk bark fibers were then removed and washed with water at 80 to remove the remaining hemicelluloses and lignin adhered to the fibers; they were then thoroughly rinsed with water. Finally, the fibers were dried to remove free water and placed in a glass container in a conditioning chamber.…”

“…According to GB5889-86 (China National Standard, 1986), the chemical constituents of the raw and degummed cotton stalk bark fibers with different caustic soda concentration were tested. Temperatures up to 150 C, from the literature, 8 were selected to investigate the effect of the caustic soda concentration on the constituents of the cotton stalk bark fibers at a high temperature, and the results are shown in Table I. As shown in Table I, the cellulose, hemicellulose, and lignin in the raw cotton stalk bark fibers were 41.05, 21.41, and 18.46%, respectively.…”

The high‐temperature degumming technology of cotton stalk bark fiber was studied, and the effects of the caustic soda concentration on the constituents, structure, and thermal degradation of the cotton stalk bark fiber were examined. The morphology, structure, and thermal degradation of the cotton stalk bark fiber after high‐temperature degumming were investigated through scanning electron microscopy, Fourier transform infrared (FTIR) spectroscopy, wide‐angle X‐ray diffraction, and thermogravimetric analysis. The results indicate that the high‐temperature degumming process was effective for removing hemicelluloses and lignin and could improve the thermal stability of the cellulose. The raw and degummed cotton stalk bark fibers both showed the structure of cellulose I, according to the FTIR spectroscopy and X‐ray diffraction results. It was interesting to note that the crystallinity and crystallinity index were related to the caustic soda concentration. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012

“…The results showed that the compatibility of the mixture directly inuences the foaming ability and a small amount of cationic surfactant can be added to the anionic surfactant to improve foam stability. 11 Although there have been many reports about new foaming agents, improving the foaming ability of foaming agents is still a challenge.…”

To develop a highly efficient foaming agent, the fluorocarbon surfactant (4-hydroxyethylether) (pentadecafluoroalkyl) amide was designed and synthesized and the surface activity and foaming performance were investigated through surface tension, surface viscosity and foaming performance measurements. The results show that the fluorocarbon surfactant has superior surface activity and can reduce the surface tension of water to 15.3 mN m À1 . When used as a foaming agent, it also shows great advantages over conventional hydrocarbon surfactants. For the sake of cost reduction, sodium dodecyl sulfate (SDS) was added to construct a highly efficient foaming agent. The results show that the mixture has superior surface activity and great foaming ability. Surface viscosity measurements show that surface viscosity of the mixture is much higher than that of single SDS. The foam integrated value of the mixture is enhanced by about 67% compared to SDS. The optimized formula of the foaming system is 0.03-0.08% HPA4 + 0.20-0.40% SDS.
