The application relates to the technical field of data analysis, and discloses a karst fissure identification-based open-pit mine blasting parameter optimization method and system. The method comprises the following steps: obtaining karst fissure distribution characteristic data through multi-source detection, establishing a three-dimensional fissure network topology structure, analyzing static breaking agent inflation stress propagation rules, performing multi-objective optimization solving based on stress propagation direction and intensity distribution to obtain an initial blasting parameter combination, and obtaining dynamic adjustment blasting parameters through real-time tracking and regulation according to fissure dynamic evolution in the blasting process. The application solves the problem that static blasting parameters cannot be real-time regulated according to the dynamic evolution state of the fissure network in the blasting process, resulting in deviation between the blasting effect and the expected target.

This invention belongs to the field of medical image processing technology, specifically relating to a method for abdominal multi-organ medical image segmentation based on a state-space model. Addressing the shortcomings of existing technologies such as the difficulty of CNNs in modeling long-distance dependencies, the high computational complexity of Transformers, and the large semantic gaps, incomplete segmentation contours, and easy organ encroachment issues in VM-UNet skip connections, this solution makes key improvements: It constructs an improved VM-UNet-Skip architecture, placing skip connections before downsampling to reduce the semantic gap between the small decoder features; it introduces a multi-scale global-local information aggregation module, capturing global anatomical dependencies through multi-head Mamba units and enhancing local detail representations with a convolutional gated feedforward network; and it relies on the VMamba encoder-decoder to achieve efficient feature extraction and reconstruction. The method flow includes: constructing initial feature representations through patch embedding layers, extracting multi-scale hierarchical features through the encoder, enhancing features through an information fusion module, and fusing and mapping the enhanced features to obtain the segmentation result through the decoder. This invention effectively improves the segmentation accuracy of abdominal multi-organs, solves the problems of insufficient contour integrity and organ encroachment, while reducing the number of model parameters and computational complexity, providing reliable technical support for clinical diagnosis and surgical planning.

The application relates to a contact analysis method and application of an arc tooth bevel gear based on tooth surface topology modification, and belongs to the technical field of gear transmission analysis. The method is as follows: based on basic geometric parameters and machine tool machining parameters of the arc tooth bevel gear, a meshing equation and a pinion conjugate tooth surface equation are constructed, and then a topology modification model is obtained; based on the meshing equation and the pinion conjugate tooth surface equation, an instantaneous contact line Gamma0 on the pinion conjugate tooth surface is established, and then through projection and inverse projection, an actual pinion tooth surface instantaneous contact line Gamma1 corresponding to the Gamma0 is obtained; the contact area boundary of the tooth surface is demarcated through the topology modification model, and the Gamma0 and the Gamma1 are contact-aligned through an angular positioning angle; distance judgment and contact analysis are carried out on the contact-aligned instantaneous contact line, and corresponding contact characteristics, namely a contact trace, a contact mark and a transmission error, are obtained. The method is helpful to improve the calculation stability of the contact analysis method, reduces the calculation time, and can improve the design efficiency and quality of the arc tooth bevel gear.

This application provides a method for adaptive alignment and intelligent evaluation of cold chain data in dual-stream mode, relating to the field of cold chain logistics technology. The method includes the following steps: receiving a sensor data packet uploaded by a cold chain preservation box, including sensor data collected locally by the preservation box, the corresponding local timestamp, and the local serial number; comparing and analyzing the received sensor data packet with existing records of the same preservation box in the cloud database within the corresponding time interval; if the sensor data in the sensor data packet completely matches the existing records in the cloud in terms of timestamp and value, it is determined to be duplicate data and discarded; if the sensor data in the sensor data packet overlaps with the existing records in the cloud in terms of timestamp but the values ​​are inconsistent, conflict calibration is performed to generate consistent data; if the sensor data packet corresponds to a missing time period in the cloud records, it is inserted into the cloud database to fill the data gap; based on the cleaning and alignment results, continuous and consistent temperature and humidity time series data for the cold chain preservation box is generated and stored.

This utility model discloses an adhesive sealing device, belonging to the field of packaging sealing technology. It includes a sealing mechanism comprising two folding sections and an adhesive tape pasting section. Each folding section includes an upward control lever and a gathering control lever. The two upward control levers are used to control the upward folding of excess packaging film. The two gathering control levers can move towards each other in the left-right direction via corresponding first slide rails, so that the excess packaging film after folding is compressed and gathered by the two gathering control levers. The two folding sections can move backward synchronously, so that the gathered excess packaging film is folded around the periphery of the roll to be sealed by the obstruction of the two upward control levers. The adhesive tape pasting section is used to cooperate with a roller to paste and wrap adhesive tape around the periphery of the roll to be sealed. This adhesive sealing device aims to solve the problem in the prior art where heat sealing of roll packaging makes it difficult to reuse or repackage the film, significantly improving the convenience and flexibility of packaging.
