In contrast to existing approaches, this methodology eliminates the requirement for analog auxiliary circuit configuration while obviating the necessity of employing extensive matrix operations and inverse Fourier transform computations. The employment of the phase difference elimination technique, in conjunction with the approximate calculation of the inverse tangent function, has been demonstrated to yield enhanced calibration performance and optimized design resource utilization. The register transfer level (RTL) simulation results demonstrate that for a 12-bit four-channel TIADC model, the amplitude of the mismatch-induced spurs is suppressed below −82 dB following calibration, and signal-to-noise and distortion ratio (SNDR) and spurious-free dynamic range (SFDR) reach 72.6- and 83.7-dB frequency of sampling (FS), respectively. The experimental results of the field-programmable gate array (FPGA)-based measurement demonstrate that, under the sinusoidal input frequencies of 498 and 1448 MHz, the SNDR increased by 27.4 and 24.5 dB, respectively, both prior to and following calibration.

However, the accuracy of UAV localization is significantly affected by systematic and random errors in attitude data, and the nonlinearity of the measurement model, together with the unknown distribution of measurement noise. To achieve robust and precise localization in long-distance oblique scenarios based on dynamic platforms, this article proposes a Gaussian Mixture Filter-incorporated self-attention (SA) Residual Neural Network (GMAR) algorithm for target localization. Firstly, an end-to-end SA residual neural network (SA-ResNN) model is built to accurately model both systematic and random errors in attitude angle. The SA mechanism is innovatively introduced to enhance the global feature representation capability of the residual module. Then, the Gaussian mixture (GM) filter utilizes a GM model to model the prior and posterior probability density functions, which can effectively capture the uncertainty in the state probability density function under nonlinear measurement models and enhance the robustness of the localization system.

However, existing methods struggle to address the challenges of poor image quality and insufficient information under low-light conditions, leading to a decline in detection accuracy and affecting driving safety. To address this issue, we propose YOLO-LLTS, an end-to-end real-time traffic sign detection algorithm specifically designed for low-light environments. YOLO-LLTS introduces three main contributions: the high-resolution feature map for small object detection (HRFM-SOD) module retains more information about distant or tiny traffic signs compared to traditional methods; the multibranch feature interaction attention (MFIA) module interacts features with different receptive fields to improve information utilization; the prior-guided feature enhancement (PGFE) module enhances detection accuracy by improving brightness, edges, contrast, and supplementing detailed information. Additionally, we construct a new dataset, Chinese Nighttime Traffic Sign Sample Set (CNTSSS), covering diverse nighttime scenarios.

Accurate condition monitoring of HVCBs is vital to reduce maintenance costs and consequently to enhance the grid reliability. However, achieving this with low-cost measurement devices, which often provide noisy signals, poses a significant challenge. In this article, a novel defect classification framework for HVCBs is proposed that uses the Savitzky–Golay filter to preprocess the most common condition monitoring signal, which is the trip/close coil current. This filter is well-known for denoising while preserving critical signal features. Following signal preprocessing, a robust defect detection and classification methodology is introduced, combining time-series similarity assessment techniques, such as Euclidean distance and dynamic time warping (DTW), with machine learning (ML) algorithms. Moreover, an experimental setup is designed to emulate the behavior of an HVCB’s coil mechanism. To further enhance the model transparency, Shapley additive explanations (SHAP) analysis is applied, providing interpretability into feature contributions toward model decisions. The obtained results validate the effectiveness of the proposed hybrid approach, demonstrating its potential to provide a cost-effective, accurate, and reliable solution for HVCB condition monitoring.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-9"},"PeriodicalIF":5.9,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145021364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Continual learning (CL) has been introduced to the field of fault diagnosis (FD), aiming at constructing an FD model with continuous evolution capability. However, the current research has the following limitations: 1) assigning parameters for each task independently leads to a linear increase in model complexity and 2) it relies heavily on the quality and completeness of historical data and the research on incremental FD under few-shot conditions is not sufficient. To address the above limitations, this article proposes a prototype learning framework for motor incremental FD (PLFIFD) under few-shot conditions. First, a prototype classifier based on distance metric is proposed to avoid uncontrollable changes due to the update of parameters in the output layer. The prototype set is dynamically expanded instead of assigning network parameters individually. Second, a multiobjective loss function is designed to jointly optimize the classification boundary and prototype space distribution to enhance intraclass compactness and interclass separability and to improve the generalization ability under few-shot conditions and stability in dynamic scenarios. Finally, the effectiveness of PLFIFD is verified on induction motor (IM) and permanent magnet synchronous motor (PMSM).","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-11"},"PeriodicalIF":5.9,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145011341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accurately identifying fault impulse signatures in bearing signals under complex operating conditions is a key challenge in bearing fault diagnosis. Therefore, this article proposes a bearing fault time–frequency diagnosis method [time-frequency complex sparse coding K-SVD (TFCSCK)] based on the time-reassigned multisynchrosqueezing transform (TMSST) and the improved k-singular value decomposition (KSVD) algorithm [complex KSVD (CKSVD)]. First, TMSST is used to obtain a high-resolution time–frequency representation (TFR) to enhance the accuracy of impulse signature localization. Second, to address the problem that the traditional KSVD algorithm only works in the real domain and ignores time–frequency phase information, a CKSVD algorithm is proposed. This algorithm utilizes complex sparse coding and dictionary updating to preserve the time–frequency phase characteristics, improving the robustness of feature extraction under complex interference. Third, a transient component time–frequency mask decomposition (TFTCD) algorithm is proposed. This algorithm preserves the time-domain waveform details of the fault impulse through mask-weighted separation and inverse transform reconstruction. Finally, the effectiveness of the proposed method is verified using numerical simulations and real fault signals. The experimental results show that TFCSCK improves the accuracy of inner race fault frequency extraction by 2.53% compared to TMSST and KSVD on the inner race data of the TYS1-8 platform. Based on measured data from aircraft engine bearings, even when both TMSST and KSVD fail, TFCSCK still extracts high-speed rotational frequency and inner race fault frequency.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-10"},"PeriodicalIF":5.9,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145027977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, with the advancement of deep learning, data-driven methods have been proven to effectively solve this issue through trained neural networks. However, current mainstream data-driven models predominantly adopt simple multilayer perceptron (MLP) architectures. These architectures exhibit inherent limitations in scalability and interpretability when processing IMU data, resulting in inefficient parameter utilization and suboptimal positioning accuracy in inertial navigation applications. Hence, this article proposes a novel data-driven model named KANet, which consists of two key components: recurrent Kolmogorov–Arnold networks (RKANs) and long short-term memory (LSTM)-inspired memory management units. RKAN fundamentally integrates the powerful function approximation capability of Kolmogorov–Arnold networks (KANs) with the sequential modeling strength of recurrent neural networks (RNNs), while the LSTM-inspired memory mechanisms enhance temporal dependency modeling in long sequences. By leveraging learnable activation functions for nonlinear pattern representation with effective memory retention characteristics, this architecture enhances the model’s capacity to process complex sequential IMU data. This innovative design overcomes the limitations of traditional models in processing complex sequence patterns, demonstrating competitive accuracy and improved parameter efficiency in multistep time-series prediction. Experimental results demonstrate that the proposed framework achieves superior performance compared with traditional PDR models and state-of-the-art neural networks, exhibiting higher parameter efficiency across diverse datasets while maintaining high positioning accuracy. In addition, comprehensive benchmarking against tactical-grade IMU systems reveals that KANet-assisted consumer-grade MEMS sensors can achieve positioning accuracy that, in certain aspects, approaches or even matches the performance levels of higher precision IMU systems.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-13"},"PeriodicalIF":5.9,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144998069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its performance degrades significantly when measuring objects with complex surface reflection characteristics, as light undergoes interreflection and subsurface scattering during measurement, generating indirect light signals that lead to reconstruction errors. Dual profilometry, a computational 3-D profilometry based on dual photography theory, overcomes this limitation by treating each camera pixel as a single-pixel detector to isolate the direct light signals. While theoretically effective, existing implementations need the reconstruction of millions of dual images. To overcome this limitation, we present an efficient reconstruction method that avoids dual image reconstruction. Experimental validation demonstrates that the reconstruction speed can be substantially improved compared with existing dual profilometry implementations, achieved without compromising reconstruction accuracy. The proposed method effectively resolves the efficiency bottleneck that has hindered the practical adoption of dual profilometry, enabling its deployment in practical applications such as industrial inspection and high-resolution biomedical surface characterization.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-19"},"PeriodicalIF":5.9,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145061802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
