With the increase of enterprise informatisation, database security and compliance operation management have become increasingly important. Therefore, it is essential to design an efficient database proxy approval system. In this paper, we develop a database proxy approval system based on the MySQL protocol for fortress machines, which provides a real-time customised configuration scheme for high-risk commands, designs a real-time approval process for six types of high-risk commands, and creates a simple and efficient matching algorithm for high-risk commands. We designed a large number of experiments to test the system’s connection success rate, operation stability, response time, CPU resource consumption, matching algorithm performance, and other aspects. The experimental results show that this database proxy approval system has good configuration flexibility, high accuracy, and good time performance. This system has a wide range of applications in electric power, finance, petroleum, and other fields. © 2025 Inderscience Enterprises Ltd.

As a unique local dialect, Waxiang dialect carries rich regional culture and historical information. However, with the acceleration of modernization and the increase of population mobility, the inheritance and protection of Waxiang dialect are facing severe challenges. By constructing the 'Xuewatong' APP- Waxiang dialect digital protection platform, based on cloud storage technology, digital resource display, multimedia integration and other technologies, and providing learning resources through big data analysis of user needs, it can effectively promote the digital recording and preservation of Waxiang dialect language resources, and significantly improve the dissemination and educational effect of Waxiang dialect culture, showing the great potential of digital technology in dialect protection. © 2024 IEEE.

The evaluation of burn degree is a key step to guide the treatment of patients with thermal injury. In this work, multiple parameters including intensity, accumulative and local birefringence features based on dual-detection polarization sensitive optical coherence tomography (PS-OCT) are proposed to quantitatively describe the information of skin burn. The results demonstrated that the intensity and the cumulative phase retardation and local phase retardation information of skin decrease with the burn degrees, since thermal damage to the collagen structure of dermal layer. In addition, the slopes of accumulative phase retardation dependent of depth are extracted for characterization of normal and damaged skins. Finally, the local phase retardation not only distinguishes the normal and damaged skin, but also evaluates the burn depth. Therefore, multiple parameters using dual-detection PS-OCT can detect the anisotropic change of birefringence of skin tissue caused by thermal injury and reveal the potential for burn assessment. © 2023 SPIE.

To address the issue of water surface garbage pollution, a new energy-powered intelligent water surface garbage recycling boat has been designed. The intelligent water surface garbage recycling boat takes the STM32F103 single-chip microcontroller as the core control unit. And it integrates some modules such as visual recognition, Beidou/GPS dual-mode positioning, and millimeter-wave radar. The unit module design method and the collaborative working mechanism of each module effectively guarantee the realization of the functions of the intelligent water surface garbage recycling boat. Specifically, the motor driving module ensures the normal running and steering of the water surface garbage recycling boat. Besides, the visual module facilitates garbage recycling and intelligent classification on the water surface. Moreover, the Beidou positioning module is utilized not only for daily navigation of intelligent fixed-point garbage recycling, but also for the recovery and utilization of solar and wind energy from all directions. In addition, the millimeter-wave radar on the hull can ensure the safe travelling of the garbage recycling boat comprehensively. The boat designed in this paper exhibits the characteristics of low energy consumption, high performance, and energy conservation and emission reduction. © 2024 IEEE.

In this paper, a selection underwater power line communication (UPLC) and hybrid free-space optical/radio frequency (FSO/RF) system is studied, where the connection between the UPLC link and the hybrid FSO/RF link is through a decode-and-forward (DF) relay. More specifically, we assume that the hybrid system transmits the same data with the same data rate over both links simultaneously. New closed-form expressions for the outage probability (OP), the average bit-error-rate (ABER), and the average channel capacity (ACC) are derived for the system. Finally, simulation results are provided to verify our analytical results. © 2024 IEEE.

Aiming at the problem of quality assurance of intelligent logistics service in 5G+ edge computing environment, this paper proposes a mechanism based on federated cooperative cache, which aims to utilize the computing and storage resources of edge nodes to realize rapid processing and sharing of logistics data and improve the efficiency and reliability of logistics services. This paper first analyzes the characteristics and challenges of intelligent logistics services under 5G+ edge computing environment, and then introduces the concept and principle of federated cooperative cache, as well as its application scenarios and advantages in intelligent logistics services. Then, this paper designs an intelligent logistics service quality assurance mechanism based on federated cooperative cache, including five modules such as data partitioning, data transmission, data fusion, data access and data update, and gives the corresponding algorithms and processes. Finally, this paper verifies the effectiveness and performance of the proposed mechanism through simulation experiments. Compared with the traditional centralized cache and distributed cache, the proposed mechanism can reduce the data transmission delay, improve the data hit rate and data consistency, so as to ensure the quality of intelligent logistics services. In the future, the federated collaborative cache mechanism can be further optimized to consider the needs of multiple scenarios. And explore the application potential of other areas to drive the continuous development and innovation of intelligent logistics services. © ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2024.

The refinement and intelligent control of shield tunneling is the development trend of modern tunnel construction technology. In order to better predict and control the surface subsidence caused by shield excavation, this paper takes the shield construction of Luoyang Metro Line 2 from Longmen Station to Longmen Avenue Station as the background, and proposes a method based on edge intelligence for shield construction in water-rich sand egg strata. Methods for predicting land subsidence. First, low latency and faster data processing are achieved by collecting a large amount of data containing dynamic information about geological conditions and surrounding environments during the shield tunneling process;then using the iFogSim simulator to create different configurations;second, establishing support A surface subsidence model based on vector regression was established, and the model was deployed on the edge equipment;finally, the model was evaluated using the monitoring data of surface subsidence of the water-rich sand egg formation in Luoyang area. The research results show that the edge computing-based system has lower latency and higher processing speed than only deploying cloud data centers. After Pearson-related parameter tuning and model comparison training with Linear as the kernel function, the mean square error of the predicted value and the collected value of the surface subsidence is better than the other two kernel functions. The method proposed in this paper can provide real-time prediction service for large-scale surface subsidence prediction caused by shield construction, and is more practical. © 2023, ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering.
