Abstract: A detection method for infrared thermal image damage area of coal rock includes: step 1: collecting and recording the infrared thermal image of coal rock in the process of loading destruction; step 2: processing a gray-scale transformation on the collected infrared thermal image of coal rock; step 3: denoising an infrared thermal image of coal rock after the gray-scale transformation by the dense residual image denoising algorithm of autocorrelation network; step 4: conducting an area segmentation on the infrared thermal image of coal rock after denoising to extract eigenvalues by using a coal-rock infrared thermal image damage area segmentation algorithm of improved encoder-decoder network; step 5: observing the damage area of coal rock. The detection method improves the denoising effect of the infrared thermal image of coal rock, strengthens the extraction of the characteristics of the damage area, and improves the accuracy of the segmentation.

Abstract: The present invention discloses an interactive behavior understanding method for posture reconstruction based on skeleton and image features. The steps are as follows: constructing and preprocessing the data set, extracting skeleton and image features, fusing and reconstructing these features, and conducting experimental evaluation and validation. This method retains the purity of skeleton features for human behavior information extraction and uses image features to retain effective environmental information, complementing the model feature information. Skeleton features are extracted using a graph convolution network, enhancing the relevance of input skeleton point information for accurate feature extraction. Effective image features are quickly and accurately extracted through the Vision Transformer network combined with a multi-head attention mechanism.

Abstract: The present disclosure provides a laser-annealing method for fabricating large-grain perovskite films for perovskite solar cells based on optimal conditions including laser wavelength, scanning speed and laser power. Compared with the conventional technology, the present laser-annealing method provides the laser-annealed perovskite films with better crystallinity and larger grains thereby improving the photovoltaic performance of the perovskite solar cells.

Abstract: A system and method for guiding and distributing network load flow is proposed and characterized by providing service-providing equipment with better packet routes to reduce the load flow of a routing device. At least two service-providing devices are connected to enable the routing device to guide the packets sent by a user-end device into the at least two connected service-providing devices for allowing the service provider used by the user to process requested services and thereby reduce the number of times of sending data packets to the routing device. In the case that the subscriber has applied for multiple network services, the packets only need to be requested once with the connected service-providing equipment in order to complete all network services.

Abstract: A system and a method are provided for guarding against dispersed blocking attacks in a network. The system includes detection apparatus for detecting and guiding the dispersed blocking attacks, and a guarding apparatus for receiving and filtering the flow of packets guided by the detection apparatus. The guarding apparatus includes a filtering module for filtering irregular packets according to preset filtering rules; a routing device for receiving and transmitting the filtered flow of packets; and an adjusting module for analyzing the filtered flow of packets, thereby adjusting the preset filtering rules and providing warning messages. The method includes detecting, guiding and filtering, in a multi-layered manner, irregular packet flows at major nodes of the network; and enhancing filtering based on the analyzed and adjusted preset filtering rules, thereby preventing network services from being interrupted by dispersed blocking attacks.
