The two commonly used sources in the multi-transient electromagnetic (MTEM) method, square-wave and m-sequence, have different anti-noise performance which had been theoretically discussed in previous studies. But the onshore contrast experiment had rarely been conducted. An onshore experiment was performed over the Laizhou gold deposite, China, and the results obtained with two different source signatures were compared and analyzed. The signals had the same amplitude similar to 40 A and about the same length, so they had approximately equal energy. Two data sets with extremely different signal-to-noise ratio (SNR) were acquired with different source-receiver offsets. The skin-depth of two sources was analyzed;the recovered earth impulse responses indicated that m-sequence can compensate the high-frequency attenuation handsomely and the powerline noise suppression of m-sequence is 22 dB greater than the suppression of the square-wave, which demonstrated the superiority of m-sequence in MTEM data processing.

The data acquisition of engine operating status is of momentously significance throughout the entire lifecycle of products. In this paper, an engine data acquisition system has been developed based on STM32. Based on the system, the output data from temperature, oil quantity, and pressure sensors could be collected through signal conditioning to obtain the cylinder temperature, exhaust temperature, oil quantity, lubricating oil quantity and pressure, rotating rate of engine, and all information is sent through the CAN bus. Thus, the acquired signals could be transmitted to the upper computer, which could also be applied as variables for real-time manipulating systems. Advantages on low cost, wide applicability, and strong extendibility, the design of our work proves to be promising tool in relevant research. © 2023 IEEE.

New Image Encryption Scheme Using Chaotic Maps 3

3rd international conference on Vision, Image and signal processing (ICVISP)

data on the Internet is always vulnerable to different types of attacks due to the public nature of the Internet, which is the only source of communication all over the world. To protect sensitive information, many encryption techniques like Gingerbreadman chaotic map and S8 permutation-based image encryption scheme are proposed. However, due to security issues in these techniques, 3D Logistic map based confusion and diffusion processes are employed which solve those security problems.3D Logistic map was used to eliminate the strong correlation between the plain text image pixels. A random matrix is created in the diffusion stage via a 3D Logistic map and XORed with the scrambled image. The final ciphertext image is extracted using existing Gingerbread-man chaotic map based S-Box. The proposed scheme is analyzed experimentally and statistically using key space analysis, information entropy analysis, and differential analysis. Results are also validated via the Number of Pixel Rate Change (NPRC) to ensure the security and robustness of the proposed scheme.

In order to effectively diagnose the rub-impact fault of rotor-bearing system, this study develops an experimental model of a two-span rotor-bearing system with rubbing faults. The rubbing experiment was carried out through the experimental platform and its analysis system, and the vibration of the rotor bearing system running under normal conditions, local slight rubbing and severe rubbing throughout the cycle are observed. The Variational Mode Decomposition (VMD) is then applied to the fault data analysis experiments of different rubbing degrees of the rotor. The experimental results further verified the effectiveness of the method, which can reveal the frequency structure of rubbing faults and accurately reflect the fault information. The findings are helpful in further understanding the dynamic characteristics of the rub-impact fault of the two-span rotor-bearing system and provide reference for fault diagnosis.

In the rapidly developing information age, the explosive growth of data increases the difficulty of big data application. Through analyzing the challenges faced by big data applications such as data collection, data timeliness, data security, data quality and data expected results, based on the key characteristics of big data and the measurement indicators of data quality, the improvement procedures of data quality are proposed, that is, following the pre-processing stage, the quality measurement stage, the quality defect identification stage and the pre-processing work tracing stage, in addition, the effect of the data quality improvement procedure is evaluated, to improve the data quality and reduce the potential risks in the application process of big data. © 2023 IEEE.

The allocation of electricity and computing resources is an important factor affecting economic development and social stability. Through research on the coordinated operation of computing power and electricity, resource allocation can be optimized, resource utilization efficiency can be improved, investment in power grid construction can be reduced, fossil energy consumption and carbon emissions can be reduced, and low-carbon and green development of electricity can be promoted. This article takes data centers as an example to study and analyze the planning and operation related issues of computing power collaboration. The focus is on the perspective of power supply and demand balance, and proposes a theoretical method for data centers to participate in demand response and achieve collaborative interaction with the power grid. Firstly, the composition of the adjustable load potential of the data center and the mechanism of participating in grid interaction were analyzed. Then, a data center energy supply and load energy consumption model is established. Finally, considering delay sensitive loads and delay tolerant loads, based on the time scheduling mechanism, spatial scheduling mechanism, and server optimization management mechanism of the data center, a potential calculation model for the participation of the data center in power demand response is proposed. This study provides theoretical support for the inclusion of the data center in power grid scheduling. © 2023 IEEE.

Considering the shortcomings of malfunction and too long action time of arc protection for traditional 10kV switch cabinet, arc protection system policy is designed in this article based on DSP. This system uses arc voice recognition, arc detection and current detection to identify switchgear arc fault, and has the advantage of strong data processing capability and fast operation. Meanwhile, wavelet analysis theory is applied to fault signal processing and recognition. This can provide reliable, secure fast arc fault protection for switch cabinet. Finally, partial discharge test platform is built to experiment, and the effectiveness and correctness of this strategy is verified by the experiment.
