With the rapid development of computer and Internet technology, using computer vision technology to evaluate the dynamic and static balance ability of athletes has become a research hotspot. This study combines the theory of functional training of human muscle groups and delves into the relationship between body function training and dynamic and static balance ability. By developing a computer vision-based algorithm, we successfully evaluated the dynamic and static balance abilities of athletes. To verify the effectiveness and reliability of the algorithm, we used simulation training experiments and comparative analysis methods. The simulation training experiment simulated the dynamic and static balance training of athletes in a real environment, and quantitatively evaluated their balance ability through this algorithm. In addition, we also compared the changes in balance ability of athletes before and after receiving functional training to verify the effectiveness of functional training in improving balance ability. The results of these validation methods all demonstrate good consistency and accuracy, further confirming the correctness of the research results on the dynamic and static balance ability of athletes based on functional training. This study not only provides new tools and methods for athlete balance training, but also a beneficial attempt for the application of artificial intelligence in the field of sports.

In recent years, knowledge graphs have had a significant impact across diverse domains. Notably, the power knowledge graph has garnered considerable attention as high-performance database. However, its untapped reasoning capabilities offer an enticing avenue for exploration. One of the main reasons is the sparsity of power grid datasets, especially electrical equipment knowledge graph. Because of the scarcity of high-risk records, there exists a large number of long tail entities and long tail relations. To address this challenge, we introduce a novel text-based model called GELMSP (Graph Embedding using Language Model with Self-learned Prompts). We employ a bi-encoder structure along with a contrastive learning strategy to expedite the training process. Additionally, our approach incorporates a self-learned prompt mechanism that generates prompts for specific situations without the need for any additional information, known as self-learning. This harnesses the power of pre-trained language models to comprehend the semantic nuances within the entities and relationships of the knowledge graph. Adopting this innovative method enables our model to effectively handle sparse datasets, leading to a comprehensive understanding of interconnectedness within the knowledge graph. Additionally, we demonstrate the efficacy of our model through extensive experiments and comparisons against baseline methods, reaffirming its potential in advancing the state-of-the-art in electrical equipment defect diagnosis.
近年来,知识图谱在各个领域都产生了重大影响。值得注意的是,作为高性能数据库,幂知识图谱获得了相当多的关注。然而,其尚未开发的推理能力为探索提供了诱人的途径。其中一个主要原因是电网数据集的稀缺性,尤其是电气设备知识图谱。由于高风险记录稀少,因此存在大量长尾实体和长尾关系。为了应对这一挑战,我们引入了一种新颖的基于文本的模型,称为 GELMSP(使用自学习提示的语言模型进行图形嵌入)。我们采用双编码器结构和对比学习策略来加快训练过程。此外,我们的方法还采用了自学提示机制,无需任何额外信息即可针对特定情况生成提示,即所谓的自学。这就利用了预先训练好的语言模型的力量,以理解知识图谱实体和关系中的语义细微差别。采用这种创新方法使我们的模型能够有效处理稀疏的数据集,从而全面了解知识图谱中的内在联系。此外,我们还通过大量实验和与基线方法的比较,证明了我们的模型的有效性,再次证实了它在推进电气设备缺陷诊断领域最先进技术方面的潜力。

Extracting to enhance the accuracy of diagnosing bearing faults in steam turbines, a novel approach focused on extracting key fault features from vibration signals is introduced. Recognizing the complex, non-linear, and non-stationary nature of bearing vibration signals, our strategy involves a sensitivity analysis utilizing a multivariate diagnostic algorithm. The process begins with collecting vibration data from defective bearings via the TMI system. This data is then subjected to Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (CEEMDAN), enabling the integration of adaptive noise for the extraction of in-depth information. Following this, an analysis in both time and frequency domains — post Fast Fourier Transform (FFT) — is conducted on the decomposed signals, forming the basis of a diagnostic features database. To streamline data analysis and boost the model’s computational efficiency, a combination of eXtreme Gradient Boosting (XGBoost) and Mutual Information Criterion (MIC) is applied for dimensionality reduction. Furthermore, a deep belief network (DBN) is implemented to develop a precise fault diagnosis model for the bearings in rotating machinery. By incorporating sensitivity analysis, a diagnostic matrix is crafted, facilitating highly accurate fault identification. The superiority of this diagnostic algorithm is corroborated by testing with real on-site data and a benchmark database, demonstrating its enhanced diagnostic capabilities relative to other feature selection techniques.
为了提高汽轮机轴承故障诊断的准确性,我们引入了一种从振动信号中提取关键故障特征的新方法。考虑到轴承振动信号的复杂性、非线性和非稳态性,我们的策略包括利用多变量诊断算法进行敏感性分析。首先通过 TMI 系统收集故障轴承的振动数据。然后对这些数据进行带有自适应噪声的完全集合经验模式分解(CEEMDAN),从而整合自适应噪声,提取深度信息。随后,对分解后的信号进行时域和频域分析--后快速傅立叶变换(FFT)--形成诊断特征数据库的基础。为了简化数据分析并提高模型的计算效率,采用了极梯度提升(XGBoost)和互信息标准(MIC)相结合的降维方法。此外,还采用了深度信念网络(DBN)来开发旋转机械轴承的精确故障诊断模型。通过结合灵敏度分析,建立了诊断矩阵,为高精度故障识别提供了便利。通过对真实现场数据和基准数据库的测试,证实了该诊断算法的优越性,证明了它相对于其他特征选择技术的更强诊断能力。

Materials with perovskite structure are known to exhibit fascinating physical properties such as high-temperature superconductivity, negative thermal expansion (NTE) and colossal magnetoresistance. However, transition metal trifluoride perovskites are less well studied compared to their oxide counterparts though they display marked differences such as NTE behavior in ScF3. Doping of such MF3 perovskites has been the focus of the experimental work of Morelock et al. [1] which provides a comprehensive structural study of the material class Sc1[Formula: see text]Ti[Formula: see text]F3. As shown in Fig. 1, there is a structural phase transition assumed to be tied to tilting of corner sharing octahedrons in this class of crystal structures which is believed to have an electrostatic dipolar origin, seen for example even in AlF3 [2]. However, the insulating and magnetic properties of TiF3 are closely related to the transition metal 3d-electrons. The extra valence [Formula: see text]-electron that Ti carries compared to Sc [1, 3] gives rise to unusual electronic and magnetic properties.
众所周知,具有包晶结构的材料具有迷人的物理特性,如高温超导性、负热膨胀(NTE)和巨大的磁阻。然而,与对应的氧化物相比,对三氟化过渡金属包晶石的研究较少,尽管它们显示出明显的差异,如 ScF3 中的负热膨胀行为。Morelock 等人[1] 的实验工作重点是掺杂此类 MF3 包晶,他们对 Sc1[式:见正文]Ti[式:见正文]F3 这类材料进行了全面的结构研究。如图 1 所示,在这一类晶体结构中,存在着一种假定与角共享八面体倾斜有关的结构相变,这种相变被认为是由静电偶极引起的,甚至在 AlF3 [2] 中也能看到这种相变。然而,TiF3 的绝缘性和磁性与过渡金属 3d 电子密切相关。与 Sc 相比,Ti 所携带的额外价电子[式:见正文][1, 3]产生了不同寻常的电子和磁性能。

Modern integrated circuits have active components on the order of nanometers. However, optical devices are often limited by diffraction effects with dimensions measured in wavelengths. Nanoscale photodetectors capable of converting light into electrical signals are necessary for the miniaturization of optoelectronic applications. Strong coupling of light and free electrons in plasmonic nanostructures overcomes these limitations by confining light into sub-wavelength volumes with intense local electric fields. Localized electric fields are intensified at nanorod ends and in nanogap regions between nanostructures. Hot carriers generated within these high-field regions from nonradiative decay of surface plasmons can be injected into the conduction band of adjacent semiconductors, enabling sub-bandgap photodetection. The optical properties of these plasmonic photodetectors can be tuned by modifying antenna materials and geometric parameters like size, thickness, and shape. Electrical interconnects provide connectivity to convert light into electrical signals. In this work, interconnected nanogap antennas fabricated with 35 nm gaps are encapsulated with ALD-deposited TiO2, enabling photodetection via Schottky barrier junctions. Photodetectors with high responsivity (12[Formula: see text][Formula: see text]A/mW) are presented for wavelengths below the bandgap of TiO2 (3.2[Formula: see text]eV). These plasmonic nanogap antennas are sub-wavelength, tunable photodetectors with sub-bandgap responsivity for a broad spectral range.
现代集成电路具有纳米级的有源元件。然而,光学器件往往受到以波长为单位的衍射效应的限制。能够将光转换成电信号的纳米级光电探测器是光电应用微型化的必要条件。等离子纳米结构中光与自由电子的强耦合克服了这些限制,它将光限制在具有强局部电场的亚波长体积内。局部电场在纳米棒末端和纳米结构之间的纳米间隙区域得到加强。表面等离子体的非辐射衰减在这些高电场区域内产生的热载流子可注入相邻半导体的导带,从而实现亚带隙光电探测。通过改变天线材料以及尺寸、厚度和形状等几何参数,可以调整这些等离子光电探测器的光学特性。电互连提供了将光转换为电信号的连接性。在这项工作中,用 ALD 沉积的 TiO2 封装了间隙为 35 nm 的互连纳米天线,通过肖特基势垒结实现了光电探测。对于低于二氧化钛带隙(3.2[式:见正文]eV)的波长,光电探测器具有很高的响应率(12[式:见正文][式:见正文]A/mW)。这些质子纳米隙天线是亚波长、可调谐光电探测器,在宽光谱范围内具有亚带隙响应率。

The application of multimedia technology in physical education classroom teaching has become increasingly widespread. It not only enriches teaching methods and makes the classroom more lively and interesting, but also enhances students’ learning interest and participation. Through multimedia technology, teachers can more intuitively display the essentials of actions, helping students better understand and learn. In addition, multimedia technology can also provide rich information resources to help students understand more sports knowledge and improve their overall quality. This paper introduces the basic concepts and characteristics of multimedia technology, including its interactivity, integration and innovation.

In order to deeply analyze the causes of English learners’ procrastination in e-learning and its influence on learning effect, an artificial intelligence (AI)-based method is designed to analyze the influencing factors of procrastination. By using K-means algorithm, this method divides learners’ online learning procrastination into two categories: active procrastination and passive procrastination, and collects corresponding learning state data samples. Then, taking into account various factors, including students, teachers, and the environment, we identified 11 key factors that may contribute to learning procrastination. Then, using the artificial intelligence-based procrastination factor ranking analysis model and the cuckoo search algorithm-trained XGBoost model, we trained multiple decision tree models to learn and predict the association between these influencing factors and different procrastination types of learning states. The experimental results show that after the application of this method, through in-depth analysis of the phenomenon of procrastination in students’ online English learning, different types of procrastination and their influencing factors are successfully identified, and an effective intervention model is designed based on the analysis results, which significantly improves students’ learning efficiency and provides strong support for the intervention of procrastination. It is proved that this method has certain significance for the accurate analysis of learning delay factors and effective intervention of procrastination in English e-learning.

Static random-access memory (SRAM) is an essential component in the architecture of modern microprocessors and VLSI circuits. The problems of high power consumption, large area, circuit complexity, and data stability against noise are among the most important indicators of performance and obstacles to the current use of SRAM. Ternary, quaternary, and higher-order logic (MLV) systems have shown the potential in overcoming these limitations in increasing the information density compared to the traditional binary system. The quantum dot channel field-effect transistor (QDC-FET) and quantum well Spatial Wavefunction Switched field-effect transistor (SWS-FET) are a new alternative with multiple operating states, low power consumption, and smaller footprints. This work presents a new four-state SRAM design that uses SWS-FET and compares it with Voltage-Mode CMOS Quaternary logic design. In addition, this work studies the noise margin in the memory circuit of the quadrilateral logic system and its effect on data stability. Furthermore, this study shows the reliability of quaternary SRAM design by evaluating the impact of errors.
静态随机存取存储器(SRAM)是现代微处理器和超大规模集成电路结构的重要组成部分。功耗高、面积大、电路复杂、数据对噪声的稳定性等问题是性能的重要指标,也是目前使用 SRAM 的障碍。与传统的二进制系统相比,三元、四元和高阶逻辑(MLV)系统已显示出克服这些限制、提高信息密度的潜力。量子点沟道场效应晶体管(QDC-FET)和量子阱空间波函数开关场效应晶体管(SWS-FET)是一种新的替代方案,具有多工作状态、低功耗和更小的占地面积。本研究提出了一种使用 SWS-FET 的新型四态 SRAM 设计,并将其与电压模式 CMOS 四元逻辑设计进行了比较。此外,这项工作还研究了四边逻辑系统存储器电路中的噪声裕量及其对数据稳定性的影响。此外,本研究还通过评估错误的影响,展示了四元 SRAM 设计的可靠性。
