The paper proposes the typical model and the functional structure of reflexive-active systems of artificial heterogeneous intelligent agents within the multi-agent approach to the construction of distributed artificial intelligence systems. Reflexive-active systems of artificial heterogeneous intelligent agents are characterized by the dynamic composition and structure of agent connections, which are formed during the joint problem solving as a result of modeling each other's reflexive positions. Thus, self-organization of the system is ensured with the involvement of currently relevant versions of agents that implement modern information and intelligent technologies, and the formation of a collective subject relevant to the problem posed. The development of such systems for solving practical problems will make it possible to obtain new theoretical, methodological and technological knowledge about collective intelligence, increase the relevance of these systems to real teams of specialists, and also verify knowledge about collective processes and effects in small groups. © 2023 IEEE.

Given the intricate three-dimensional structure and variable density of lung tissue, accurate airway segmentation remains a challenging task. This study proposes a method rooted in an enhanced U2-Net t architecture that excels in identifying small peripheral bronchi in non-contrast CT scans. Replacing all ReSidual U-blocks in the U2-Net network with three-dimensional convolutions enables direct processing of CT images. Furthermore, the introduction of Instance Normalization enhances the model's capacity to discern individual features. Optimization of upsampling and downsampling mechanisms minimizes information loss during sampling and preserves crucial image details. We also employed an advanced Loss function, expediting model convergence. Experimental results indicate that these enhancements substantially elevate the performance. Our method surpasses existing strategies by extracting a more extensive array of fine branches. © 2023 ACM.

In response to real-time detection requirements for bird nests and other hidden danger on power grid transmission lines, this paper proposes a lightweight real-time detection system of bird nests. In terms of bird nests on transmission towers, there are many small targets, which may lead to possible loss of data. Thereby, the algorithm detects small targets of bird nests through three scales: low, middle and high scales. At the same time, the DIoU-NMS calculation method is utilised to make the prediction box closer to the real box. The average accuracy of the improved algorithm is 90.05%, 7.38% higher than the original one. The detection speed of the detection system of bird nests in NVIDIA Xavier NX, an embedded device, is 26.3 FPS. With higher detection accuracy and real-time detection speed, the requirements of high-precision and real-time inspection of State Grid in line inspection can be met. © 2023 Inderscience Enterprises Ltd.

In the test sequence optimization generation problem, the generated test sequences are usually problematic cannot be well applied in practical testing. In order to make the test sequence cover the test sub-sequence with the minimum number of test cases and can be applied in the actual test, a test sequence optimization meth-od is proposed. First, taking the mode conversion function of on-board equipment of a new type of train control system (CTCS-n) as an example, a test sequence generation method based on Traveling Salesman Problem (TSP) is introduced to convert the test sequence optimization problem into a TSP problem. Then, the requirements for test sequence generation are put forward according to the actual test work experience, and a solution algorithm based on simulated annealing (SA) algorithm is given. Finally, examples are introduced for validation and analysis, and the results show that the test sequences generated in this paper are more in line with the actual needs of testing compared with previous methods. © 2025 SPIE.
