Abstract: Disclosed herein are method, system, and computer product embodiments for generating a textual summary of a data set based on traversing a decision tree according to sequence and rank numbers related to a query. Subsets of the data set may receive a rank number indicating the relevancy of the subset of data to the query. In response to traversing the desicion tree, a textual summary representative of the data set and subsets of data may be generated and displayed. The textual summary may also include a course of action recommendation based on the culmination of the data set and relevant data subsets.

Abstract: A method for evaluating an aging state of a silicone rubber composite insulator includes: step 1: collecting samples from the silicone rubber composite insulator, and subjecting samples in a surface layer and a center layer successively to hydrophobicity, flexing resistance, hardness, color, and absorbance tests; step 2: determining relevant data of the samples in a natural evolution process according to the tests in step 1; step 3: subjecting the samples to thermo-oxidative aging; and after the thermo-oxidative aging is completed, subjecting the samples to a hardness test of artificial accelerated evolution, and calculating position coordinates (F1, F2) of the samples in an aging space; and step 4: classifying the samples in advance and solving an aging state centroid of each classified population, calculating a minimum aging distance based on the position coordinates in step 3, and evaluating the aging state of the silicone rubber composite insulator.

Abstract: Disclosed herein are aspects for dispersing a non-fungible token in response to a security program. An aspect begins by generating a three-dimensional virtual world. The aspect continues by receiving a request to access a test program as part of a security program in the three-dimensional virtual world. The test program includes a display of a source code and instructions for a user to resolve an associated challenge. The aspect then determines a tier of the user, where the tier indicates progress of the user in resolving challenges corresponding to the security program. The test program is generated based on the tier of the user and is generated on a user device through a perspective of a virtual camera. The aspect continues by receiving a resolution to the challenge. A non-fungible token is then generated based on the resolution, assigned to a digital wallet, and recorded on a blockchain.

Abstract: The disclosure relates to a spray gun, and particularly relates to a suction pipe rotating device, and a spray gun with same. The device includes: a rotary knob rotatably arranged at a top of a gun body of the spray gun; a rotary connecting portion, where one end of the rotary connecting portion is arranged on the rotary knob and is movably inserted into a material suction hole of the spray gun; and an angle suction pipe including a straight pipe and an inclined pipe that are connected to each other, where the straight pipe is rotatably arranged in the material suction hole and is connected to the other end of the rotary connecting portion, the inclined pipe is obliquely arranged, and an end of the inclined pipe is close to a joint between a side wall and a bottom of a material barrel of the spray gun.

Abstract: An integrated detection test device for a drill bit and a rotary blowout preventer and a detection method thereof are provided. The test device includes a support frame, a rotary shaft is mounted on the support frame, and an upper end of the rotary shaft is connected to a piston rod of a first hydraulic cylinder fixed on the support frame; and the rotary shaft is connected to a driving device through a rotary disc sleeved outside the rotary shaft. A pit sinking to a fixing plane of the support frame is arranged below the support frame; and an L-shaped track and a transport vehicle slidably connected to the track are mounted in the pit and used to transport the rotary blowout preventer or the drill bit test bench to a test position.

The device includes a test box body and a rotary blowout preventer body, a base is fixedly connected inside the test box body with screws, and two first receiving blocks are fixedly connected to a top of the base with screws. Through the arrangement of the structures such as a motor and an output shaft, the motor is started, the output shaft is driven to rotate, a rotating rod is driven to rotate, a forward-rotating screw rod and a reverse-rotating screw rod are driven to rotate, a right-moving sliding block and a left-moving sliding block are driven to move.

Abstract: Systems and methods for voice-enabled transactions are disclosed. A merchant system may generate a transaction request comprising a transaction amount and a merchant identifier. The merchant system may invoke an audio signal generator to generate an audio transaction signal comprising the transaction request data. A voice assistant may play the audio transaction signal. The user initiating the transaction may use a mobile device to detect and ingest the audio transaction signal. In response to detecting and ingesting the audio transaction signal, the mobile device may interact with a payment network to authorize, process, and complete the transaction request. The payment network may transmit a transaction approval to the merchant system.

Abstract: A method for calculating a surface relaxation rate of a shale includes: a relaxation time T distribution curve and a pore throat radius r distribution curve are obtained through experiments; abscissas of the two distribution curves are standardized, and the abscissa of the relaxation time T distribution curve is expanded or shrunk to ensure an abscissa value corresponding to a maximum ordinate value in the transformed relaxation time T distribution curve is same as an abscissa value corresponding to a maximum ordinate value in the pore throat radius r distribution curve; straight lines with a number of N parallel to a y-axis of a combined curve graph including the two distribution curves are drawn and a ? value corresponding to each straight line is calculated; and ? value with the number of N are processed to obtain a final surface relaxation rate ??.
