Abstract: A transaction record is created showing a purchase transaction of a customer. A CV profile showing a list of items in the transaction obtained from images is also obtained. The items in the transaction record are compared to items on the list. When there is a discrepancy, an action to take is determined.

Abstract: The invention provides a method for evaluating deep-buried tunnel blasting parameters, and belongs to the technical field of mine engineering. The method comprises: setting multiple diverse blasting schemes; selecting a plurality of test sections with the same geological characteristics, the number of the test sections corresponding to the number of the blasting schemes; blasting the test sections using the blasting schemes, and obtaining diversified monitoring data of each test section; and comparing the diversified monitoring data to select the optimal blasting schemes for the test sections. According to the method for evaluating the deep-buried tunnel blasting parameters, by implementing different blasting schemes in test sections with the same geological characteristics, diversified monitoring data of the test sections are obtained and compared to select the optimal blasting schemes for the test sections, so as to ensure the safety and quality of blasting excavation of deep-buried tunnels.

Abstract: A method for preparing biochar and hydrogen by utilizing anaerobic fermentation byproducts, the method including: (1) mixing a first straw, seeding sludge and distilled water, and then carrying out anaerobic fermentation to obtain a mixed product after fermentation; (2) performing separation on the mixed product to obtain a second straw and biogas slurry; and (3) carbonizing the second straw to obtain biochar, and collecting gas after a pressurized catalytic reaction on the biogas slurry to obtain hydrogen.

Abstract: In a data processing method, a first device obtains a plurality of first commands. To ensure an execution sequence of the plurality of first commands, the first device performs encapsulation on each first command to obtain a second command. The encapsulation includes adding a sequence identifier for each of target commands in the plurality of first commands that have an order-preserving requirement. The first device sends the plurality of second commands in parallel. The second device receives the plurality of second commands in parallel and performs decapsulation on the second commands to retrieve the first commands with their sequence identifiers. The second device then schedules the plurality of first commands for execution based on their sequence identifiers.

Abstract: The present invention provides a method for generating hydroxyl radicals and removing organic pollutants in water by utilizing an organic membrane. The inventive method generates hydroxyl radicals by adopting a nitrocellulose membrane as a photocatalytic material, placing the nitrocellulose membrane in water, illuminating with the sun or a sunlamp having a wavelength above 280 nm as a light source, and causing the nitrocellulose membrane to undergo a photochemical reaction at the membrane surface, and the generation rate of hydroxyl radicals can be achieved by adjusting the surface area of the membrane and a light intensity. The generated hydroxyl radicals can remove phenol, bisphenol A, thiamphenicol and other typical organic pollutants in water very well.

Abstract: The system controls one or more VCRs to perform various operations including rapid and accurate tape repositioning from any point to any other point utilizing time codes and VCR performance data. They system includes the ability to encode, record, and reproduce a video signal with time codes and other information such as text commentary, directories to the tape content and VCR commands. Tapes prepared on any implementation of the system can be positioned on any other implementation except that the copying process must translate as appropriate between different signal formats (NTSC, PAL, SECAM), tape formats (VHS, Video 8, etc.) and encoding systems. The system includes a method for characterizing the tape transport performance of individual VCRs in the various tape transport modes including fast forward and rewind and during transitions between transport modes.
