The Vienna Rectifier is an AC-DC converter system with features that allow for a high output voltage and minimal ripple compared to a conventional rectifier that does not draw current from the grid. The main differences between conventional and Vienna rectifiers are harmonics, power factor, and efficiency. The Vienna rectifier reduces grid-side harmonics and improves the power factor. In this research, the current in the Q-axis is controlled to zero so that the power factor of the system is as close to one as possible, and a PI controller is used to create a stable output signal for the system. The result is that the system can produce an output voltage level of 800V and a THD of less than 5%, according to ieee 519-2022 standards. The efficiency of the input signal has been improved, which can reduce the THD of the input as well. The research also tested software designed with C2000 microcontrollers to prove that the designed model can operate in real-life situations.

The current research on optical-SAR cooperative work mainly focuses on the fusion of optical and SAR images, while there are fewer studies on how the optical and SAR sensor can cooperate optimally for targets survey. In this paper, mutual information is employed as the evaluation metric of optical-SAR cooperative system. Firstly, the optical-SAR cooperative system is modeled according to imaging principles. Then the mutual information expression of the optical-SAR cooperative system is derived with the stochastic process theory. Finally, through simulation, the relationship between the mutual information of the cooperative system and the target detection probability is analyzed to verify the validity of the mutual information as the performance evaluation metric of the cooperative detection system. © 2024 ieee.

This paper measures and analyzes the key mechanical, thermal and electrical properties of several typical polypropylene (PP) insulation materials from Chinese and international companies and completes the selection of polypropylene insulation materials. Building upon this foundation, we carried out performance evaluation and selection research compared with low density polyethylene, and identified the polypropylene insulation base materials that are potentially suitable for medium-voltage AC and DC cables. Building upon this foundation, the material formula research has been completed. Subsequently, a 10kV DC polypropylene-based insulated cable and a 35kV AC polypropylene-based insulated cable using the same insulation material formula were produced, and type tests and electrical margins were carried out to verify the performance of the newly developed cable system.

Traditional image steganography techniques have revealed many drawbacks due to advancements in steganalysis and steganalysis detection technologies. With the continuous development and improvement of various generator-free models, more and more researchers are shifting their focus to the combination of image generation models and steganography techniques. Compared to traditional methods, generative steganography directly drives the secret information to generate images containing the hidden data, exhibiting better resistance to detection against existing statistical feature-based steganalysis. This paper describes and analyzes GAN-based steganography algorithms as well as the latest steganography algorithms based on diffusion models and deep generative models. At the end of the paper, current issues in generative steganography are discussed, along with future research and development directions. © 2024 ieee.

Interrupt-driven programs are widely used in safety-critical fields like aerospace and embedded systems. However, the unpredictable interleaving of Interrupt Service Routines (ISRs) can lead to concurrency bugs, particularly atomicity violations when ISRs preempt atomic sequences of instructions. To address this, we propose a dynamic approach for detecting atomicity violations in interrupt-driven programs. Extensive experiments demonstrate that our method is more precise and efficient than related approaches.

With the rapid development of Autonomous Rail Rapid Transit technology, lithium-ion battery as its main power source, the research of its charging technology has become particularly important. At present, the charging scheme of lithium-ion battery mainly includes two ways: single high-power charging and multiple low-power charging modules in parallel. However, the single high-power charging scheme has the problems of high cost and low efficiency, and the traditional parallel charging method lacks effective module management strategy, resulting in unbalanced load between modules during charging, affecting charging efficiency a nd safety. A iming at the shortcomings of current research, this paper proposes a parallel charging scheme of multiple DC-DC modules based on cooperative control. By designing a closed-loop control system of current inner loop and voltage outer loop, the precise control and cooperative work of parallel modules are realized. The experimental results show that the scheme not only improves the charging efficiency, but also ensures the stability and safety of the charging process, which provides an effective and reliable solution for the lithium-ion battery charging of the intelligent rail train. © 2024 ieee.

Intelligent manufacturing is a product of the deep integration of advanced manufacturing and new generation of information technology. However, current teaching of computer majors in colleges and universities for the cultivation of talents in this field is still very weak to match the enterprises' expanding demand. To address this issue, this paper explores how to conduct the relevant curriculum construction in the software engineering specialty. Specifically, the teaching objectives, course content, teaching methods, evaluation mechanism, and other related aspects is instigated to adapt to the actual professional reality, student foundation, and teaching expectations. Further, the iterative improvement of each part was carried out through the nearest two semesters of teaching practice, and the results demonstrated the feasibility of curriculum development. The research in this paper will help to provide a useful reference for the development of advanced manufacturing technology courses for information majors in colleges and universities.
