This paper designs and develops a set of portable comprehensive detection system based on virtual instrument technology. The detection system consists of laptop computer, engine parameter recorder, dynamic test data acquisition device and other hardware. The upper computer communicates with the lower computer through the 422 buses. With the corresponding automatic detection software, the scanning path setting, automatic sensor probe scanning, detection data preprocessing and microdefect imaging can be realized. The miniaturization, modularization and automation of the high precision measurement and control system are realized by using all digital design, improving the signal conditioning circuit of DDS technology and using virtual instrument technology. The test results show that the system can accurately reflect the test parameters, working conditions and test curves of the tested aero-engine. © 2023 IEEE.

The great explosion of data processing and the reliance on information technology are results from the widespread of computers. This results in the need for huge memory for data storing and fast transmission rate. Thus, two challenges nowadays facing information technology namely reducing the required memory size to save data on storage media and reducing the required time for data exchange between computing nodes. Many techniques were developed in both directions and others are still in progress and development. In this paper a method is introduced to reduce the size of text and image documents by utilizing the similarities between adjacent bytes in the document content. The method is analyzed and assessed experimentally using MATLAB to show its capability to reduce the size of such documents. The results are then extracted and discussed. © 2023 IEEE.

Magnetic flux leakage (MFL) nondestructive testing technology uses magnetic sensors to detect the magnetic signal on the surface of seamless steel tube. In this process, the magnetic sensors are used to detect the flux leakage signal from the defects exist in the tube. The defects are located on the external or internal surface of the tubes with significant longitudinally or transversely oriented forms. This paper proposes a defect recognition and classification method based on spectrogram and convolutional neural network (CNN), which converts magnetic flux leakage signals frames obtained by sensors into spectrograms and sends them into convolutional neural network as input data for defect classification. The experiments show that the steel tube defects classification performance was 71% for method proposed in this paper. © 2023 IEEE.

To promote the energy-saving transformation of industrial enterprises effectively, it is important to accurately grasp the energy consumption behavior of enterprises. In this study, the multi-type industrial enterprises in an industrial park located in Shanghai are selected for analysis. Based on the collection and processing of the measured heating (steam) data, by employing the big data analysis method, the cluster analysis is carried out from different dimensions including user difference, load fluctuation and typical daily characteristics. Following which, the multi-type load characteristic curve is obtained, and the energy consumption characteristics of the whole industrial park and different types of industrial enterprises are discussed. On this basis, the energy load forecasting model of industrial enterprises is developed based on the LSTM neural network, and the effect of introducing meteorological data on the accuracy of load forecasting is analyzed.

Photoplethysmography (PPG), commonly integrated into wearable devices, is widely utilized for detecting human activities and various physiological parameters. This study focuses on employing a feature-oriented and prime feature selection-based methodology in tandem with machine learning models like SVM and Decision Tree for effectively classifying human activities using wrist PPG data. The research underscores a clear relationship between essential features, relevant data points of features, their importance on target, and accurate classification of human activities derived from the PPG signals. The proposed approach demonstrates high accuracy, achieving 96.7% and 91.0% in two publicly available datasets. These results provide strong evidence of the efficiency and potential of features-based machine learning approaches in human activity classification from PPG signals. © 2023 IEEE.

High-voltage(HV) voltage transformers(VT) are widely used in the power industry, and their accuracy is directly related to the interests of power users and power grid-related enterprises. Therefore, it is of great significance for transformer verification. However, nowadays it mainly relies on manual verification, which is inefficient, and the verification work in a high-pressure environment will threaten the safety of the verification personnel. In this regard, the HV voltage transformer detection system developed in this paper based on digital signal processor (DSP) reduces manual intervention, not only improves the accuracy and reliability of verification results, but also improves the safety level of verification operations. In the application analysis experiment of the detection system, the phase test experiment of the voltage signal proves that the phase output accuracy of the verification system designed in this paper meets the design requirements. © 2023 IEEE.

High-finesse optical enhancement cavities (OECs) are powerful and versatile tools for various scientific investigations and measurements. They offer superior optical performance and have been widely researched and utilized. Finesse is a crucial parameter for OECs. It is essential to measure finesse accurately for OEC applications. Here, we outline the current development and potential applications of high-finesse OECs and introduce several finesse measurement methods. An OEC system with a length of 3.78 m is built and stable locking is achieved. Finally, the finesse is measured experimentally to be approximately 15,000 by the free spectral region (FSR) modulation method. © 2023 SPIE.
