However, existing region-based methods for detecting objects in PMMW multipolarization imaging suffer from the poor performance of regional segmentation. To address the concerns mentioned, this article presents an iterative method combining fuzzy fusion and Fisher vectors, named ICFFFV. First, the multipolarization membership degree vectors from contrast images of low BT (CILBTs) are analyzed. This leads to a multipolarization fuzzy fusion that constructs potential target regions. Next, a new index searching-assisted re-segmentation strategy is introduced from the analyses of inaccurate segmentation and superpixels near the body edge. It mitigates the impact of inaccurate object segmentation and superpixel interference near the body edge. Finally, the subregional contrast of the Fisher vector (SCFV) image is combined with the fuzzy fusion image. Following a feedback-based iterative manner, it protects the edge pixels of objects while suppressing clutter pixels. The experiments validate the enhancement performance and the effectiveness of improving detection performance at pixel and region levels.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-15"},"PeriodicalIF":5.6,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143937977","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}

GCF analysis can represent a simple and noninvasive tool for monitoring periodontal and bone remodeling during the orthodontic tooth movement (OTM). Previous work has demonstrated that Fourier transform infrared (FT-IR) spectroscopy on GCF gives interesting information on the changes occurring in protein, lipid, and carbohydrate contents during orthodontic treatments. Consequently, FT-IR spectroscopy can be considered a useful tool for monitoring OTM in a clinical environment. To this aim, it is important to shorten the spectra acquisition times and optimize the data analysis procedures. In this article, a faster procedure for collecting GCF spectra has been adopted by exploiting the attenuated total reflection (ATR) contact sampling method, which allows the collection of good-quality infrared spectra with no sample preparation. In this case, the spectra have been directly acquired on the supports used for collecting GCF avoiding any time-consuming extraction procedure. Furthermore, to optimize the data analysis procedures, different methods have been applied and new biomarkers have been identified for promoting a robust and rapid characterization of GCF, allowing more personalized orthodontic treatment by reducing any side effects.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-7"},"PeriodicalIF":5.6,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144073072","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}

Random matrix-based ETT often presumes that the measurement points are evenly dispersed across the entirety of the ellipse object. However, its performance will significantly decrease when measurement points are SDD. The proposed VBSDD-ETT approach not only solves this issue, but also obtains recursive estimation within a Bayesian framework. Specifically, a new Gaussian mixture model that uses translations, scaling, and rotations of subellipses is proposed to address the problem of SDD. Second, a VBSDD-ETT approach based on the Gaussian mixture model is presented to derive the posterior distribution in an analytical form. Also, we propose a VBSDD-ETT-based information-theoretic interacting multiple model (ITIMM-VBSDD) algorithm to tackle the problem of model uncertainty caused by the maneuvering of the target. The ITIMM-VBSDD algorithm can obtain more accurate estimation results of the kinematic state and extension. Finally, the performances of VBSDD-ETT and ITIMM-VBSDD are evaluated in the simulation and real scenarios.

Unlike conventional CT systems, this static CT acquires full projection views in axial scanning mode using a focus-shifting technique combined with small-angle gantry rotation. This unique scanning protocol limits the angular range of each source, enabling complete scan acquisition. However, the large cone angle between the sources and the detector, combined with the uneven clustering of projections inherent in multisource acquisition, leads to significantly incomplete projections. Consequently, significant cone-beam artifacts and uneven sparse-angle artifacts coexist, degrading the reconstructed image quality. To address these issues, this article proposes a deep iterative network based on directional total variation (DTV) regularization (DTV-Net). DTV-Net incorporates DTV as a regularization term within the fast iterative shrinkage-thresholding algorithm (FISTA) framework, achieving both artifact suppression and rapid convergence. Specifically, it employs an encoder-decoder architecture and a head attention block (HAB) module to adaptively adjust threshold parameters in the gradient space, effectively removing redundant gradient information corresponding to artifacts. During end-to-end training, we integrated the ASTRA toolbox with tensorized representations and introduced a tensorized projection operator (TPO) tailored for the multiflat-panel detector array, optimizing iterative forward and backward projections. Extensive experiments demonstrate that the proposed DTV-Net algorithm outperforms prior art solutions on both simulation and clinical data.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-14"},"PeriodicalIF":5.6,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144072786","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}

Independent component analysis (ICA) is then applied to extract non-Gaussian independent source features from the image data, which serve as input to a random forest (RF) model. Second, a mechanistic model is used to construct the temperature field within the blast furnace.

Principal component analysis (PCA) is then used to extract principal components, which serve as input to an ensemble of random vector functional-link networks (RVFLNs).

The reference cavity, constructed by fusing an SMF at both ends of a capillary tube, ensures high stability.

Furthermore, by setting the FSR of FPI1 to approximately half that of a modified reference cavity (FPI3), the FHVE enhances sensitivity to −83.03 nm/MPa, 27.86 times greater than FPI1. The sensor demonstrates minimal temperature cross-sensitivity, with gas pressure variations of only 2.44 kPa/°C.

To address this challenge, we propose a surrogate modeling approach that trains a conditional generative model to approximate the output of the reference numerical model. Specifically, we introduce dual-domain conditional generative adversarial networks (DD-CGAN) to generate contact force (CF) curves for various PCS parameter configurations. The generator network takes system parameters as input and produces the corresponding CF curve, while the discriminator network distinguishes between real and predicted curves in both the time and frequency domains, ensuring greater consistency. Furthermore, the feature fusion module is proposed to extract and integrate time- and frequency-domain features by using a multiscale channel attention (MSCA) mechanism. Extensive experimental results demonstrate the effectiveness and advantages of DD-CGAN for surrogate modeling of pantograph–catenary interactions. The CF curves generated by our method exhibit high consistency with simulation results from high-fidelity numerical models with a mean absolute error (MAE) of 0.9815, which is six times more accurate than state-of-the-art methods.
