Abstract ：
The outstanding performance of current machine-learning fault diagnosis methods is mainly attributed to the availability of a large amount of labeled training data. However, in practical dynamic weighing systems, the high costs and variability of operating conditions limit the availability of reliable training data, hampering engineering fault diagnoses in dynamic weighing systems. To address this issue, this study proposes a novel cross-sensor fault diagnosis method based on multi-feature fusion using a transfer component analysis (TCA)-weighted k-nearest-neighbor (WKNN) network. Using this method, time- and frequency-domain features are extracted from a laboratory-simulated set of fault data with small batches of real operational data. Source and target domain features are fused, and TCA is applied to map the source and target domain samples to a latent space using kernel functions to reduce the distribution differences among the samples. Finally, the WKNN is employed as a metric learner to enhance small-sample data matching and classification to improve diagnostic accuracy. The results show that with three samples per support set, the proposed method achieves a diagnostic accuracy of 93.33%. Compared with other approaches, the proposed method exhibits stronger generalizability for diagnostic knowledge transference from sensor to dynamic weighing failure data, effectively improving precision in on-site small-sample environments and reducing sample imbalances.

Abstract ：
In response to the high-precision and multi-dimensional force measurement requirements in the fields of biology and medicine, this paper proposes a novel three-dimensional microforce measurement method based on the broadband optical coherence. A novel, compact, and low-coupling elastic element was designed, with a maximum outer diameter of 26 mm and a capacity of 50 g in the X-, Y-, and Z-directions, respectively. The functional relationship between the displacements of the three detecting points on the elastic element and the applied external force was derived based on the elastic mechanics theory. And it was also verified by the finite element method. A self-built optics system was set up to sense the displacements of the three points on the elastic element. The experiments results showed that the resolution in the X-, Y-, and Z-directions was 0.10 mN, 0.11 mN and 0.13 mN, respectively. In the measuring range of (10-50) g, the maximum coupling rate was 4.55 %, and the maximum linear error was 4.70 %. The maximum repeatability error was only 0.615 %. The method and sensor were verified with good characteristics of high resolution, low coupling rate, high linearity and high accuracy, comparing to other reported researches. The multi-dimensional force measuring method could be used in the fields of biology and medicine.

Abstract ：
The study of deadweight force standard machines (DWM) that operate over a wide range is at the leading edge and a hot spot in force metrology. Optimizing the combination method of the weight load has important theoretical significance for improving the stability and accuracy of DWMs. Firstly, the law of weight loading position on a pendulum relevant to the hanging system through dynamical theory and finite element methods was studied, likewise the minimum pendular degree caused by the loading on the upper end of the hanging system was determined. Then, a method for optimal combination of weights was presented and carried out using MATLAB software. A force transducer of 1000 kN was selected to test on a 2 MN DWM, and the results show that the method can effectively improve the repeatability and linearity. Finally, compared with two random combination methods, the repeatability deviation decreased by more than 50%, and the linear deviation by approximately 10%.

Abstract ：
A novel weight sensor based on the Michelson interferometer is proposed in this study to meet the demands of complex environments. The sensor uses a dual-beam type elastic element, optimized to enhance its sensitivity. Its deformation under load is sensed by a broadband optical coherence displacement measurement system, which, in combination with the spectrum correction method, enables displacement sensing down to sub-nanometer res-olution. An optical interferometric weight sensor with a rated load of 6 kg is fabricated under laboratory con-ditions, and its performance is verified experimentally. The proposed weight sensor demonstrates good stability and achieves a sensitivity of 146.814 mu m/kg, theoretical resolution of 0.004 g, nonlinearity error of 0.034%, maximum repeatability error of 0.036%, and maximum hysteresis error of 0.055%, with the relative error of the identification threshold not exceeding 0.1%. The proposed weighing method and sensor represent a significant improvement over other reported interferometer-type weight sensors.

Abstract ：
Nanoscale polymeric coatings have been developed and utilized in a wide range of industries for decades. The ability for quality control at nanoscale is critical to large-scale industrial development. Nondestructive testing (NDT) techniques play vital roles in structural health monitoring of the nanocoatings throughout their lifetime stages. In terms of recent advances in quality control of nanocomposite coatings, here we present and discuss the commonly used inspection techniques for ex-situ detections, as well as the promising in-situ or inline monitoring methods, with a focus on the application of NDT techniques. Future development of NDT techniques for polymeric nanocomposite coatings will be directed toward intelligent and automated inspection systems, in order to avoid errors caused by human factors and further improve accuracy and reliability. © 2023 Elsevier Inc.

Abstract ：
Terahertz (THz) technology has firmly established itself as an effective sensing and nondestructive testing (NDT) technique for the detection of substances and physicochemical evaluation of materials and structural systems since its first emergence almost three decades ago. To date, both the effectiveness and accuracy of this technology have been extensively demonstrated in a myriad of applications across the spectrum of research and development all the way to process analytical technology (PAT), quality control, NDT, and structural health monitoring. These applications are generally enabled by the production and availability of advanced, versatile, robust, highly accurate, and industrially rugged THz spectroscopy and imaging (THz-SI) systems, the unique properties of THz waves compared with other electromagnetic waves, as well as the advancements in electronics, photonics, and THz metamaterial systems development. This article presents a comprehensive state-of-the-art and state-of-the-practice review of sensing and NDT applications of THz technology and analyzes the role of THz metamaterials in enhancing the resolution and sensitivity of THz systems. The study also provides a general overview of the fundamentals of THz-SI systems and discusses the suitability of THz sensing and NDT in a variety of real-world application scenarios (e.g., composites' defect detection and evaluation, paints and coatings thickness measurement and characterization, and biomolecule detection). Aspects, such as the noise caused by the presence of barriers, challenges with experimental implementations and operability of THz systems, long times required to acquire THz images, as well as limited customizability and portability of currently available THz systems, are also discussed.

Abstract ：
Torque is one of the mighty core parameters of rotating machinery, and it has profound implications for the success of many engineering and industrial manufacturing activities. To date, more and more torque sensors are being researched and manufactured to meet the requirements of torque measurements in all of the engineering sectors that rely on accurate measurement of torque parameters for their success. A direct implication of these constantly growing developments is the recent development of various torque sensors, which operate based on more than ten different principles. Although several measurement principles have been created, torque sensors themselves can only be divided into two categories based on whether they come into contact with the rotating objects being measured (contact sensors) or do not have any point of contact with these objects (contactless sensors). In this paper, the concept of contactless sensors for torque measurement is redefined and the major classes of torque sensors (i.e., contactless sensors based on the laser Doppler effect, laser speckle effect, and optical coherence vibrometer, etc.) are introduced outlining the main progress, challenges, and future directions involving torque measurement applications. As the key to the success of torque measurement systems, some advanced signal processing techniques that are commonly used to enhance the accuracy of the torque measurement data are also introduced.
