Existing approaches remain limited in measuring ARF on individual microscale objects at this frequency and size scale, particularly when object localization and acoustic streaming must be considered. Here, we propose a displacement-based method using a compliant microscale mechanical transducer. A model Mie-regime SiO<sub>2</sub> microsphere is encapsulated within a gelatin methacryloyl (GelMA) microsphere, which converts ARF into measurable relative displacement. The mechanical properties of GelMA are independently measured by atomic force microscopy and incorporated into a mechanical model to reconstruct ARF from the measured displacement. The solid porous matrix of GelMA reduces internal fluid motion and mitigates the bias of acoustic-streaming-induced drag on the SiO<sub>2</sub> microsphere. The method is applied to SiO<sub>2</sub> microspheres with three different diameters in the Mie regime under 100-MHz ultrasound. The reconstructed time-averaged ARF reaches tens of nanonewtons, corresponding to an ARF amplitude during the acoustic-on interval at the micronewton level. The displacement-tracking limit corresponds to a nominal time-averaged force resolution on the order of hundreds of piconewtons, and repeated measurements yield an average relative standard deviation of 9.7%. Finite element analysis is further conducted, showing consistency with experimentally measured ARF trends. The proposed method offers a practical approach for quantifying ARF in UHF acoustic actuation.</div></div>","PeriodicalId":18349,"journal":{"name":"Measurement","volume":"292 ","pages":"Article 123559"},"PeriodicalIF":6.1,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149212729","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 UniDA, accurate detection of unknown samples is the core challenge. However, many existing UniDA methods rely on feature representations learned directly from raw signals, where marginal distribution variations and fault-discriminative characteristics are highly entangled, resulting in degraded feature alignment and unreliable unknown identification. To address these issues, a Physics-Informed Disentangled Network (PIDN) is proposed, which leverages the excitation–transfer correspondence in vibration responses to learn representations with different sensitivities to different shifts. First, based on cepstral analysis, a Physical Decoupling Layer (PDL) is designed to decompose the measured response into two components: transfer-related features and excitation-related features. Building upon this, a Transfer Manifold Augmentation (TMA) mechanism is developed to generate similarity-adaptive intermediate representations within the transfer-related feature space, thereby facilitating unknown fault detection. Simultaneously, an Excitation Consistency Constraint (ECC) loss is formulated to suppress condition-induced variability in excitation-related features by enforcing consistent energy distribution patterns across operating conditions.

This study presents a systematic assessment of the accuracy and noise sensitivity of sectioning-based methods, focusing on residual stresses induced by double-sided dimpling (DSD). A combined experimental–computational framework is developed, integrating a direct finite element simulation of the deformation and cutting process with an inverse solution based on the Contour Method. The latter reconstructs residual stresses from measured displacement fields using an auxiliary finite element model. Experimental validation is performed using confocal profilometry, X-ray diffraction, and FIB-DIC. A numerical experiment is conducted to evaluate the influence of noise in displacement data on the reconstructed stress fields. The results show that the Contour Method remains stable at low noise levels (5–10%), while higher noise levels lead to rapid degradation of the solution. For a representative 10% noise level, the reconstruction error is on the order of 40 MPa, corresponding to a displacement uncertainty of approximately 2.3 μm. To improve stability, a surrogate–rational experimental–computational correlation (surrogate-RECC) approach is introduced. By approximating displacement profiles with a Gaussian function and quadratic background, the method filters noise and reduces the effective error to about 5–6 MPa (≈0.35 μm), representing an improvement by a factor of 6–7. The proposed framework enables quantitative uncertainty estimation for the Contour Method and provides a practical route for improving robustness in residual stress analysis.</div></div>","PeriodicalId":18349,"journal":{"name":"Measurement","volume":"291 ","pages":"Article 123202"},"PeriodicalIF":6.1,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148999594","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}

High-density plasmas were generated from a brass target using a pulsed Nd:YAG laser, and a continuous-wave (CW) probe beam passed through the expanding plasma along multiple lines of sight.

Unmanned aerial vehicle (UAV) inspection offers a promising acquisition modality, but deploying deep-learning detectors on edge devices faces three challenges: defect morphological diversity, limited resolution of small-scale damage, and constrained onboard computation. This paper proposes BR-DETR, a lightweight variant of RT-DETR-R18 with three task-specific components. The C2f-DIMB backbone employs dynamic multi-branch depthwise convolutions with heterogeneous kernel geometries to adapt the receptive field to diverse defect morphologies while reducing backbone parameters. The Multi-Scale Small Defect Enhanced Pyramid (MSDEP) injects fine-grained P2-level information into the feature pyramid to improve small-defect sensitivity without adding a detection head. The AIFI-HiLo encoder decomposes self-attention into frequency-specialized branches for high-frequency boundaries and low-frequency structural context. On a five-class dataset of 8,924 images, BR-DETR attains 72.51% mAP50 and 54.36% mAP50-95, improving over RT-DETR-R18 by 4.67 and 5.67 percentage points while reducing parameters by 31.9% to 13.54 M and GFLOPs by 8.6%.
