A teaching concept based on a software toolbox for automated uncertainty propagation has been previously developed.

The Bayesian Linear Minimum Mean Square Estimation (BLMMSE) is introduced with AUP. It is demonstrated that concepts like the Extended Kalman Filter (EKF) and the Unscented Kalman Filter (UKF) are easily implemented following the same approach as for the already introduced uncertainty quantification, since the toolbox supports linearization, Unscented Transform and Monte Carlo methods and the code for these variants is compact and equivalent. Additionally, the uncertainty analysis of signals and parameters reconstructed from compressed measurements can be easily assessed, as well as the impact of uncertainty in the expected performance of the recovery technique. This approach facilitates the integration of complex topics—such as late fusion, posterior state estimation or sparse recovery—into measurement science education. Its applicability is demonstrated through three examples, highlighting the benefits of the Unscented Transform method for AUP in sensor and data fusion.</div></div>","PeriodicalId":18349,"journal":{"name":"Measurement","volume":"258 ","pages":"Article 119109"},"PeriodicalIF":5.6,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145221652","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}

Traditional fixed-spacing random paths often result in insufficient coverage and uneven surface quality. To address this issue, the article proposes a pseudo-random path planning method based on removal of regional overlap rates. According to the surface shape and curvature changes of the rotationally symmetric non-spherical surface, a path point set is obtained for achieving an equal overlap rate distribution. Moreover, the path search algorithm is optimized by adjusting the weights of the path points, allowing the paths to precisely converge at the predetermined positions. A two-layer acceleration architecture is established, including the inputting algorithm and the blocking strategy to improve the efficiency of path generation; The integrated angular velocity control module compensates for curvature differences, ensuring consistent removal depth at all locations. The experimental results show that the surface roughness variance obtained by the proposed method is only 2.49 × 10<sup>−7</sup> μm<sup>2</sup>, which is significantly lower than the 3.25 × 10<sup>−4</sup> μm<sup>2</sup> obtained by the traditional fixed-spacing random path method, thereby validating the uniform coverage and efficient path generation of this method in polishing rotationally symmetric aspherical surfaces.

More importantly, this method requires no modifications to the existing configuration or impedance adaptation of the cable, making it suitable for a wide range of cable types.

However, the experiments in this study reveal that adhesive layer inconsistencies can lead to variations in these features, particularly TOA, which may be misinterpreted as stress changes, causing significant errors in absolute stress evaluation. Therefore, a new absolute stress evaluation method that combines the Lamb wave time–frequency spectrum with the residual network (LwTFS-ResNet) is developed, which can alleviate the effect of adhesive layer inconsistencies. This model is pre-trained using a theoretical dataset generated based on the acoustoelasticity theory and a time-domain wave packet model. Once pre-trained, this model requires only a small training dataset measured from a single experimental specimen for final training. Mounting the piezoelectric wafers onto a testing specimen where stress is measured often contains variations related to the adhesive layer. The absolute stress evaluation experiments were conducted using both the LwTFS-ResNet method and the traditional TOA-based method. Adhesive layer inconsistencies caused errors in the TOA-based absolute stress measurement results (max error: 31.40 MPa, root mean square error (RMSE): 29.85 MPa), while the proposed method reduced the max error to 7.83 MPa and RMSE to 4.93 MPa, respectively.

Traditional composite error models typically separate and integrate errors using function approximation approaches, which result in limited prediction accuracy under varying temperature conditions. As a result, a deep pyramid convolutional neural network (DPCNN) model is constructed. It achieves a nonlinear mapping from position and temperature parameters to composite errors. The complexity and low accuracy issues of composite error modeling are resolved. To address the limitations of conventional coupling effect evaluation methods, an improved sensitivity analysis method is employed to quantify error coupling effects. Geometric errors are classified based on first-order sensitivity. It avoids issues arising from small differences between total and first-order indices that hinder the evaluation of coupling effects. The improved method enables a clearer analysis of coupling effects while reducing computational complexity and cost. To mitigate the influence of error coupling and enhance compensation efficiency and accuracy, an error proportion compensation approach is proposed. The compensation ratio is calculated using the error distribution characteristics output by the DPCNN, thereby enabling targeted adjustment of key error components. Experimental results show that this strategy enhances compensation accuracy while reducing the number of compensation terms.

This issue is further highlighted in industrial and manufacturing environments. For example, a fluid flow disturbance in an industrial facility can cause a significant explosion that would threaten both the facility and its operators. One promising approach to adopt is the use of data analysis (DA) and machine learning (ML) algorithms due to their effectiveness in illustrating the behavior of flow anomalies and detecting them in environments such as water transportation systems and underground pipelines. This work proposes a DA and ML-based approached to better understand the characteristics and detect flow anomalies in industrial-installed pipelines. As such, this work first proposes the use of Short-Time Fourier Transform to visualize the variation of the transmitted signal power measured for different frequency components over time. Then, representative and relevant features are extracted, normalized, and fed as input to four different supervised ML classification algorithms for flow anomaly detection. To evaluate the performance of the proposed framework, a real-word dataset collected through an industrial partner representing different working conditions is used.
