With society’s progression, the rapid advancements in science and technology, and the continual economic growth, a heightened emphasis on health and sports is observed. Sports footwear plays an indispensable role in various sporting activities, and, with the progress in science and technology, these products are continually evolving to cater to diverse requirements. Nevertheless, this evolution has led to the manufacturing and disposal of substantial quantities of sports footwear, thereby adversely impacting the environment. Our Common Future advocates for sustainable development that fulfills the present generation’s needs without jeopardizing those of the future generations. In the contemporary context, global concerns regarding sustainability have made it imperative to tackle the environmental pollution stemming from sports footwear across its life cycle. The research focuses on sports footwear and employs a modular design approach to investigate sustainable solutions for sports shoes from a sustainability perspective.In this examination of existing sustainable and modular shoes, the article aimed to elucidate their strengths and limitations concerning sustainability. Sustainable footwear of the present excels in various aspects, including the utilization of recycled materials, reduction of environmental impact, increased adaptability, and the consideration of social equity concerns. Nevertheless, the use of adhesives in assembly processes impedes recycling efforts and inflates disposal costs. In the meanwhile, modular sports footwear often lacks sustainability considerations. To address these sustainability challenges, the study embraced a comprehensive approach that places significant emphasis on full life-cycle sustainability, modular design, and the enhancement of recovery and recycling processes. The article approached the formulation of a sustainable design strategy for modular footwear from a systematic perspective. It outlined a threefold approach to constructing a sustainable modular sports footwear system. Firstly, it is necessary to create a modular system with detachable structures, tailored to user needs and sustainability. Employing the system-function-structure layering model, the article analyzed the structure and function of sports shoes to provide the foundation for module segmentation, and establish a connection with user needs. The article gathered user needs through desktop research, questionnaires, and interviews, providing the basis for module segmentation and subsequent design. In terms of structure, each module was designed without the use of adhesive, facilitating individual disassembly, thereby enhancing production efficiency and recycling ease. Secondly, material selection guided shall be by life cycle and recycling design principles, and it is necessary to prioritize natural materials with minimal environmental impact and recyclable materials. Thirdly, it is necessary to enhance the end-to-end service system design and business chain to improve the user experience throughout the entire process. From a product and service system design perspective, the article created a systematic process that spans from purchase to recycling and replacement. Finally, from the four design elements of structural division, user demand, material selection and system service, the specific design practice was verified. It is found that by applying the proposed design strategy to the specific sports footwear design, the improved solution exhibits enhanced sustainability, with an improved overall evaluation of the design’s ability to better meet user needs while striving for sustainability. Considering that it offers improved repairability but relatively weak durability, subsequent solutions can focus on further optimizing and strengthening the durability to meet evolving user demands.The modular design approach offers a novel avenue for sustainable footwear design, addressing key innovation challenges in the field. It effectively reduces the consumption of non-renewable resources, and mitigates environmental pollution by employing natural and biodegradable materials. The modular structure facilitates easy assembly and recycling, enhances production efficiency, and allows for personalized customization. Compared to traditional sports shoes, sustainable modular sports footwear caters to individual preferences while emphasizing environmental friendliness and recyclability. It preserves the performance characteristics of sports footwear and provides valuable insights for the sustainable design of sports shoes. [ABSTRACT FROM AUTHOR]

In order to enhance the automation level of metallographic image analysis and accurately obtain key information reflecting material properties such as grain size, a grain boundary segmentation method based on multi-task learning is proposed. This method designs a relationship prediction auxiliary task to improve the accuracy of grain boundary extraction by focusing on the internal information of grains. Simultaneously, contrastive learning is used to train feature extractors, making the model more targeted towards grain boundary topological structures. A metallographic microstructure recognition system based on relationship prediction task is implemented under the Pyside2 framework. Through experimental verification, this system not only assists laboratory technicians in intelligently detecting microscopic structural information such as grain size but also significantly improves the software's applicability, detection efficiency and accuracy.

To meet the security requirements of smart airports, a 5G-based smart airport network security solution was proposed.The security characteristics and security requirements of the 5G scenario in smart airport were analyzed, and the pain points of security requirements in the current scenario were summarized in five aspects:unified security management and control, network slicing security, security monitoring and early warning, edge computing security, and IoT-aware node security.And then a 5G network security system was designed for smart airports.The functional components of this system included 5G network unified security management and control functions for ubiquitous networks, lightweight 5G network identity authentication and authentication functions, 5G network slice security protection for multi-service requirements, 5G network security monitoring and early warning based on big data analysis, integrated security protection function based on edge computing, and sensory node security protection function based on device behavior analysis.This comprehensive approach built an all-in-one security platform covering business encryption, network security, terminal trustworthiness, identity trustworthiness, and security management and control.Additionally, the potential counterfeit base station attacks in the existing 5G authentication and key agreement (AKA) were analyzed.Due to the lack of authenticity verification of the messages forwarded by the SN, the attacker can pretend to be the real SN to communicate with the UE and the HN, thus carrying out the base station masquerading attack.This kind of attack may lead to the leakage of smart airport network data, and encounter problems such as tampering and deception by opponents.Aiming at the network security requirements of smart airports and the security issues of 5G authentication and key agreement protocol, an improved 5G authentication and key agreement protocol was designed.Formal security models, security goal definitions, and analysis were performed to ensure the robustness and effectiveness of the protocol against attacks.

BackgroundThe molten salt reactor (MSR) is one of the six advanced reactors identified by the Generation IV International Forum. The MSR exhibits unique characteristics, such as intrinsic safety, sustainable development, nuclear nonproliferation, natural resource protection, and economic efficiency. After a liquid-fuel molten salt reactor shuts down, residual decay heat in the reactor core is passively dissipated to the environment through a natural circulation loop of the molten salt. However, the decay heat from the molten salt in the main circuit can impact the thermal capacity of the overall system.PurposeThis study aims to determine the thermal characteristics of the passive system by establishing an analysis basis for a natural cycle model to examine the effects of natural circulation loop on the physical properties of the molten salt, the loop structure, and equipment resistance coefficient K.MethodsBased on the direct reactor auxiliary cooling system (DRACS) for MSR, the natural circulation model of the passive residual heat-removal loop of a liquid-fuel molten salt reactor was established using self-developed Python analysis program, and the temperature distribution of the molten salt in the loop was explored using the numerical model. Then, the effects of different physical properties, loop structures, and core and heat exchanger resistance coefficients K on the heat transfer and flow characteristics of the residual heat-removal system were analyzed. Finally, the effects of critical factors on the residual heat-removal capacity of the reactor core were analyzed using self-developed Python program for natural circulation calculation equations code (NCCC) and validated by using the natural cycle experimental results of the DRACS circuit in CIET1.0.ResultsThe findings indicate that the presence of decay heat from molten salt in a system loop decreases the natural circulation-driven heat transfer by the molten salt within the core. Based on the significance analysis results show that fuel salt density, specific heat capacity, and height difference between the hot and cold cores are parameters that significantly influence the natural circulation capacity. When these three parameter values are increased by 15% separately, the residual heat removal capacities increase by 26.02%, 15.00%, and 18.59%, respectively.ConclusionsResults of this study demonstrate that the molten salt properties, circuit structure, and equipment resistance coefficient all affect the natural circulation heat-removal capacity.

This paper discusses the optimization problem of improved error back propagation（BP） algorithm for mathematics teaching quality evaluation. K-means clustering is used to collect data for teaching quality assessment, and the clustering center of samples is determined. The weight and threshold of mathematics teaching quality evaluation index are determined to optimize the teaching quality evaluation. MATLAB simulation results show that under the error conditions of 0.1, 0.01 and 0.001, the accuracy and efficiency of the improved BP algorithm for teaching quality evaluation are better than the standard BP algorithm, which is basically consistent with the expected teaching quality objectives. Therefore, the improved BP algorithm can accurately evaluate the teaching quality and reduce the influence of other factors on the teaching quality evaluation results. [ABSTRACT FROM AUTHOR]

Total Harmonic Distortion (THD) is an important index to measure the nonlinear degree of channel. The automatic measurement device applied in arbitrary output waveform identification and total harmonic distortion of the audio small signal amplification system has become an effective means to detect the signal amplification performance. In order to accurately calculate the total harmonic distortion of the amplified waveform, FFT technique is adopted. In order to improve the system efficiency, high frequency sampling and half extraction techniques are adopted. Dynamic control relays, resistance-capacitance components and multi-stage amplification are used to reasonably adjust the position of the static operating point of the amplification system and the size of the input waveform to realize the output of different types of distorted waveforms. Based on microcontroller stm32f103c6, the combination switch completes the collection, identification, calculation and display of arbitrary waveform in one-button, greatly improving the working efficiency of small signal amplification systems. Matlab algorithm simulation, Multisim circuit simulation and practical test show that, the automatic calculation device of arbitrary waveform THD for small signal amplification systems consisting of multi-stage transistor amplification consistency adjustment circuit and microcontroller FFT operations can accurately and real-time identify waveforms and calculate THD. The one-button switching design is convenient to operate, saves cost, and has practical value. [ABSTRACT FROM AUTHOR]
