Its higher and lower levels can cause Cushing’s syndrome and Addison’s disease, respectively. An accurate and highly sensitive detection of cortisol levels is crucial to monitor human mental and physical health. In this sequence, we propose and simulate a sensor design based on long-range surface plasmon resonance (LRSPR) for measuring cortisol concentrations in human saliva. The sensor’s structure includes a 2S2G prism, Cytop (1500 nm), silver (18 nm), bismuth titanate (12 nm), molybdenum ditelluride (<inline-formula> <tex-math>$2times 0.82$ </tex-math></inline-formula> nm), cysteamine (5 nm), and a sensing medium (SM).

The comparison reveals that the proposed sensor significantly outperforms the conventional surface plasmon resonance (CSPR) sensor. The Finite Element Method (FEM) simulations further reveal that the proposed sensor design achieves a large penetration depth (PD) of 510.10 nm and a cortisol detection limit of 0.1765 ng/mL. The results demonstrate a significant improvement compared to the sensor reported in the literature. It shows the potential for noninvasive and accurate cortisol monitoring required for monitoring related health conditions.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 10","pages":"17324-17331"},"PeriodicalIF":4.3,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144073192","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}

However, differences in radar setup, such as frequency band and waveform of transmitted signals, across various radar devices may lead to data incompatibility, limiting the collaborative capabilities of multiradar detection systems. To address this issue, this article proposes a radar system-agnostic (RSA) learning architecture for HAR. The framework enhances HAR performance by employing adversarial training of the gradient reversal layer (GRL) and the auxiliary classifier generative adversarial network (ACGAN), with the constraints of each module mutually reinforcing effectiveness. The proposed RSA architecture is evaluated through extensive experiments using radar datasets from three devices across different frequency bands, covering 11 types of human activities. The experimental results demonstrate that the algorithm performs well in single-domain and multidomain scenarios. In single-domain training, HAR accuracy improves by at least 1.5% over the baseline. Multidomain training significantly surpasses other methods, achieving approximately 97% accuracy with three domains. An ablation study further validates the contributions of the GRL and ACGAN components, confirming that their integration is essential for achieving optimal performance. These findings highlight the practicality and advantages of RSA for robust cross-radar frequency HAR.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 10","pages":"18492-18502"},"PeriodicalIF":4.3,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144072868","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}

However, this technology requires a substantial number of microphones, which increases the complexity and cost of the data acquisition system. To reduce the number of microphones while maintaining the performance of acoustic imaging, this article introduces a concentric circular nested array (CCNA) design method. By extending the array using a differential coarray model, a virtual uniform concentric circular array is achieved. This virtual array preserves the advantages of the circular array structure while minimizing the number of required microphones. The performance of the proposed array is validated through simulation experiments. The simulation results demonstrate that the CCNA offers higher resolution, a greater dynamic range (DR), and improved positioning accuracy in acoustic imaging compared to other arrays. Finally, this article compares the acoustic imaging results of the CCNA with those of the uniform circular array (UCA) through experiments.

Deep learning flat detection methods can learn and identify flats automatically without relying on expert experience, which has attracted widespread attention. However, accurately detecting wheel flats remains challenging due to the strong interference signal components and the data imbalance from the lack of failure data. In this article, the convolutional block attention module-enhanced residual net (CBAM-enhanced ResNet) model is adopted for flat detection tasks to improve the robustness and the recognition ability of the model. To detect wheel flat for imbalanced data, a dataset expansion method based on wheel-rail dynamics simulation is proposed. In this method, the effects of wheel-flat lengths and the impact positions on flat signals were studied based on the developed vehicle-track coupled model. Then, new flat signals can be reconstructed by transforming the actual flat signal according to the obtained fitting relationships. Experiments were conducted to verify the effectiveness of the CBAM-enhanced ResNet model and the proposed dataset expansion method. The results show that the CBAM-enhanced ResNet model achieves better flat detection results than the ResNet model. After data expansion, the accuracy of both models was improved.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 10","pages":"18268-18276"},"PeriodicalIF":4.3,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144073448","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}

This means that the approaches developed are insufficient for shaping soft materials. The article describes a cheap method of reproducing plastic deformations using a robotic manipulator. The shape recording and reproduction system consists of two RGB-D cameras, two containers with kinetic sand, and a manipulator with 6 degrees of freedom (DOF). Volunteers create templates by drawing on the surface of kinetic sand with a wooden stylus or finger. Some pressure is exerted while writing. The resulting shapes recorded by the RGB-D camera have the form of ribbon ditches (grooves). The obtained point cloud is processed to create a sand deformation model. In the first stage, a dedicated local smoothing technique is used. Then, special algorithms are implemented to create a description of the main curvatures and key dimensions of recorded signs. A spline-based approach is used. The method allows for the representation of various shapes in a unified form. In the final stage, modulated sinusoidal functions define the robot’s trajectory. The effects of the robot’s operation are recorded to assess the reproduction quality. The point cloud structural similarity measure (Point SSIM) evaluates the results. Experimental research takes into account many different shapes. Copies of shapes created by humans and robots are compared with the originals. The outcomes show that the quality of reproduction achieved by humans and robots is comparable. The median-based curvature similarity measure obtained for the human was only 1.92% higher than the robot’s result, and the covariance-based geometric similarity measure was only 0.74% higher than the robot’s score.

To address this issue, this article proposes an intelligent adaptive dehazing system (IADS) that integrates range-gated imaging with deep learning, combining image acquisition and restoration for enhanced dehazing performance. The range-gated imaging system reduces scattered light interference. However, our approach primarily focuses on enhancing image quality through advanced dehazing methods. Specifically, we introduce the MSCENAFormer dehazing network, which achieves high-quality reconstruction of target scenes in dense fog by effectively removing fog and improving visibility. The core modules of MSCENAFormer include the multiscale enhanced neighborhood attention (MSENA) module and the comprehensive attention refinement module (CARM). MSENA is designed to capture rich local information in harsh environment, improving the dehazing effect and enhancing image details. CARM integrates the local and global information to optimize the visual effect further. In addition, the adaptive feature mixing (AFM) module is used to fuse multiscale features for better performance. To validate the performance of our method, we utilize our lab-collected nonhomogeneous haze real dataset, O-ITDF, along with the public datasets NH-HAZE, NTIRE2021, and NTIRE2023.

However, conventional pipeline inspection Gauges (PIGs) equipped with high-grade inertial measurement units (IMUs), which are primarily designed for normal size pipeline, cannot access small diameter or tightly curved pipelines due to their large overall size and the large-sized high-precision IMUs they rely on. This limitation leaves a critical gap in accurately locating such pipelines, as no effective method currently exists for their precise positioning. To address this challenge, we propose a novel method using an air-propelled inertial positioning ball (IPB) integrated with a chip-level micro-electromechanical systems (MEMS) IMU, so as to make the device compact and lightweight enough to traverse the small-diameter pipelines. However, it comes with a serious problem that the MEMS IMU chip has large sensor errors leading to fast position drift and therefore can only keep positioning accuracy for several seconds. Unlike the conventional PIGs, which are typically pulled through pipelines by steel cables at a low speed (around 1 m/s), the lightweight IPB is designed to be propelled by airflow, allowing it to fly rapidly (around 10 m/s) through the pipeline. This significantly reduces the integration time of the MEMS IMU, thereby mitigating its cumulative errors effectively. Field tests conducted in a 48-m-long small-diameter pipe demonstrate the effectiveness of the IPB, with single-run positioning errors of 0.77 m in the transverse direction and 1.13 m in the height direction. By averaging the results from four independent runs, the maximum positioning errors were reduced to 0.36 m (0.75% of pipe length) in the transverse direction and 0.36 m (0.75% of pipe length) in the height direction. The proposed new approach provides a practical, efficient, and accurate solution for locating small-diameter and tightly curved underground pipelines, addressing a critical gap in underground pipeline surveying.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 10","pages":"18257-18267"},"PeriodicalIF":4.3,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144073447","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}

The modeling method based on support functions (SFs) or extended Gaussian images (EGIs) needs the down-range measurement and cross-range measurement of the object to estimate the information about the object’s extent. Down-range and cross-range refer to the projection lengths of the object along and perpendicular to the radar line of sight (LOS), respectively. The down-range measurement can be generated from the high range resolution profile (HRRP). However, in some radar applications, limited by the resolution capability in cross-range, the cross-range measurements are unavailable. To track extended objects only using down-range measurements, this article analyzes the observability of the extended object in detail. The analysis results indicate that the observability of the extended object is affected by the dimensions of range extent measurement, and the required dimensions of the range extent measurement for extended object tracking vary under different motion modes. According to the analysis results, when the object performs coordinate turn motion, extended object tracking can be achieved using only down-range measurements. The results of simulation experiments confirm this conclusion. The analysis results presented in this article clarify the measurement conditions required for extended object tracking and expand the application scope of tracking algorithms based on the SF and EGI modeling.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 10","pages":"17706-17716"},"PeriodicalIF":4.3,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144073311","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}
