It is worth noting that previous studies have focused primarily on solving static algebraic Riccati equations (AREs) or interference-free TVAREs. Nonetheless, in real-world solution systems, AREs are often time-varying and subject to a variety of external disturbances. To address these problems, we propose two strong initial state discrete noise-resistant zeroing neurodynamics (SDRZND) algorithms for determining the solutions to TVAREs. First, we introduce a bounded smoothing of the strong initial state coefficient to accelerate algorithm convergence while avoiding the additional impulse noise that nonsmoothed coefficients in the discrete algorithm might generate. Then, an integral feedback term is designed and integrated with this coefficient to enhance the algorithm’s robustness. Subsequently, to further improve the algorithm’s flexibility, we introduce a variable time step, leading to the SDRZND-Euler (SDRZND-E) and SDRZND-Taylor–Zhang (SDRZND-TZ) algorithms presented in this article. Lastly, the effectiveness, noise resistance, and practicality of these algorithms are verified through theoretical analysis, numerical simulations, and sound source tracking experiments.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 7","pages":"11155-11166"},"PeriodicalIF":4.3,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is essential to suppress the environment’s magnetic field. As the environment’s magnetic field is not constant, it is necessary to compensate the magnetic field dynamically. This article presents a method of compensating the environment magnetic field dynamically for array OPMs based on real-time signal separation. The OPMs serve as the signal measurement sensors, as well as the quasi-static environment magnetic field monitoring sensors. The OPMs are placed orthogonal to each other to monitor the three components of the magnetic field. The output signals are separated and reconstructed using a fast wavelet transform. The low-frequency component is utilized to calculate the compensation current and the high-frequency component is recorded as the measurement result. This method does not require any additional sensors for magnetic field compensation, resulting in a simplified setting and low cost. The experimental results show that the method can suppress the quasi-static magnetic field fluctuations to less than one percent in real time. The magnetic field fluctuation is controlled within 10, 10, and 1 pT for the three axes. For array sensors, the effect of the magnetic field gradient can be reduced by utilizing internal coils in each OPM. The magnetic signal of a human heart is measured, which verifies the feasibility of the method for ultraweak biomagnetic field measurement.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 7","pages":"10913-10921"},"PeriodicalIF":4.3,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143761488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the magnetic, electronic, and optical properties of doped silicene have been extensively studied, there is a noticeable gap in the literature regarding its mechanical properties. To address this issue, this study explores the mechanical characteristics of bilayer silicene doped with aluminum under various conditions. By employing molecular dynamics simulations, we investigate the influence of aluminum concentration, defects, temperature, and strain rate on the material's mechanical response. The findings reveal a monotonically decreasing strength with Al concentration in both the zigzag and armchair straining directions. Additionally, the material exhibits high sensitivity to defects, with even a small percentage significantly impairing its mechanical properties. Directional dependence is also observed, with the zigzag direction showing greater sensitivity than the armchair. As strain progresses, initial mono-vacancies evolve into more complex defects, hindering predictions of the mechanical response in certain cases. Lastly, strain rate sensitivity is evaluated, yielding values of 0.0485 and 0.0365 for the zigzag and armchair directions, respectively.","PeriodicalId":449,"journal":{"name":"IEEE Transactions on Nanotechnology","volume":"24 ","pages":"134-139"},"PeriodicalIF":2.1,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10908092","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143621888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnetic sensors, valued for their compactness, low cost, and robustness to interference, show promise as traffic detectors. Yet their current vehicle detection abilities fall short of widespread deployment. This study addresses this gap by integrating magnetic sensors into smart road studs (SRSs), enabling adaptive sensing and control capabilities. Conventional detection algorithms for roadside or center-lane placement are unsuitable for sensors on lane markings. This article introduces a multilane traffic volume detection algorithm tailored for the SRS network. A multiscale convolutional neural network (MSCNN) module based on 1-D convolution is first designed to automatically extract multiscale features from individual signals. Then, the C-Transformer (C-Trans) and S-Transformer (S-Trans) encoding modules, built on Transformer architecture, are employed to capture both intrasignal and spatial intersensor correlations. By merging multiscale, correlation-based, and manually extracted features, the proposed method facilitates multilane vehicle detection. To further refine accuracy and underscore the role of key sensor nodes, a single-sensor vehicle detection approach is integrated, with the Dempster-Shafer (D-S) theory used for result fusion. Experimental results demonstrate that the proposed approach achieves multilane traffic volume detection with an error rate of approximately 1.6%, outperforming current methods.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 7","pages":"11737-11748"},"PeriodicalIF":4.3,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143761444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional segmentation methods often struggle to generalize across diverse ore types, irregular particle geometries, and complex spatial arrangements, limiting their robustness and adaptability in real-world applications. The proposed method overcomes these challenges by first using Ore-Detect, a detection module that efficiently localizes OPs, followed by a refined segmentation process using the segment anything model (SAM) to precisely delineate particle boundaries.

In conventional rotational modulation, the rotation of the IMU introduces additional errors resulting from rotational angular motion coupled with scale factor and installation error, particularly exacerbating asymmetric scale factor error. An optimal rotation scheme should eliminate inertial sensor errors without introducing new ones. Building upon the maximum rotatable angle of the IMU, a rotation modulation scheme based on time-sequence fusion (TSF) of dual RINS is proposed for the traditional single-axis two-position rotation–stop (with identical stopping durations) and single-axis four-position rotation–stop (with identical stopping durations only at symmetric positions) schemes. The proposed scheme ensures that the dual RINS is precisely timed to rotate and stop, utilizing solely the stop data derived from TSF for calculation. While modulating constant error, the rotation-induced coupling errors are effectively mitigated, and the oscillations in attitude and velocity are reduced. Simulation results show that the system positioning error based on TSF is reduced from 6.13 n mile/72 h for a single system to 1.48 n mile/72 h.
