This paper is dedicated to the design of an AI-based fully automatic leveling control system for car-mounted radar antennas. The car-mounted radar antenna is one of the key electronic devices in automobiles, but its leveling process requires manual intervention, which is inefficient and prone to errors. To solve this problem, this paper constructs an electromechanical radar antenna car seat leveling system structure, establishes a leveling support leg transfer function and a model of the relationship between the leveling platform horizontal angle and the support leg extension length. Then, an AI neural network is applied to implement the automatic leveling control system. By establishing a neural network error compensation prediction model, effective prediction of the leveling support leg extension length and leveling accuracy is achieved. Finally, the software of the leveling control system is designed, and KEIILC51 simulation and debugging are carried out. The system has good adaptability, can meet the full automatic leveling requirements of car-mounted radar antennas in various complex road conditions, and improves leveling efficiency and accuracy. This research is of great significance for the automation control of car-mounted radar antennas. © 2023 IEEE.

Requirements and conceptual model traceability is a core software engineering activity that supports decision-making during the entire software development life cycle. With traceability data sets growing, traceability visualisation techniques that properly communicate the relevant information are imperative to ensure quality, completeness, and transparency in enterprise models and information systems. We did a comparative analysis of various graphical visualisation techniques for conceptual model traceability such as graphical graphs, tabular forms, sunbursts, etc., The findings suggest that a one-size-fits-all solution does not exist because factors such as data structure, traceability purpose, and traceability-users' skills determine the level of detail, content, and type of traceability visualisation technique. As a proof of concept, this paper presents an approach towards a traceability visualization modelling tool named StoryScreen, which facilitates the visualisation of traces among user stories and conceptual models. StoryScreen allows users to identify missing traces and fix errors in conceptual models and user stories. StoryScreen provides a project management tool for user story-based projects, which includes various traceability visualisation techniques such as graphical graphs, tabular, and textual. We expect that StoryScreen will support traceability users in improving user stories and creating conceptual models employing traceability visualisations that are filterable and interactive. © 2024 Copyright for this paper by its authors.

Due to the manufacturing demand for mass customization and the widespread application of flexible automated production equipment, manufacturers tend to shorten their production cycle. This results in a loss of regularity in the production system, and it becomes difficult for manufacturers to control the product and process quality. To circumvent the issues related with these uncertainties, recent studies showed that using stochastic programming approach in Material Requirement Planning software can yield significant cost saving for the industry. However, there are very few studies that discuss uncertain production demand and lead time simultaneously. To fill these gaps, this paper considers the lot-sizing problems for production planning with uncertainties. We propose a stochastic optimization methodology for production planning with uncertain demand and lead time based on the digital twin. The proposed method is based on the simulation and Bayesian network forecast methods. In addition, we explain how the approach can be integrated with the digital twin systems. More precisely, we integrate the lot-sizing model with the simulation model, domain model, and Bayesian network model to forecast the lead time and improve the lot-sizing model with uncertain demand and lead time. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

In molecular dynamics simulation, the phase transition is a rather complex process, and the melting point of materials simulated often deviates greatly from the experimental reported ones. Therefore, this article simulates the phase transition temperature of silicon and tries to reduce the influence of the large error from the simulation results. We use the Stillinger-Weber (SW) potential to simulate the solid-liquid coexistence method and the direct heating method are used respectively to compare and simulate the melting process of silicon. The influence of atomic number on the solid-liquid coexistence simulation process of melting point is discussed, and the influence of time step and potential function directly on the melting process is further discussed. Finally, we tried to modify the SW potential function to get better results. The selected computer algorithm has been further discussed in the section "Inverse fitting Analysis". © 2022 SPIE

The problem of controlling various industrial electro-hydraulic systems (i-EHSs) under variety of nonlinearities and disturbances are made more difficult by emerging trends, the expansion of industrial automation, and the real-time control implementation. Proportional directional control valves over servo valves are becoming more and more used in a variety of industrial and crucial domains due to their numerous advantages. The electro-hydraulic experimental test equipment and associated mathematical model were established in our work using proportional directional control (PDC) valve. The development and validation of a unique discrete-time optimum position tracking controller through simulation and actual use. A variety of nonlinearities and disturbances can be seen in an electro-hydraulic system when it is used in real-time industrial applications. A novel nonlinear linear discrete constrained controller has been proposed in light of this industrial issue and confirmed in simulation as well as experimentally under external uncertainty.

Scientific research performance evaluation is a crucial method to assess the scientific research results of researchers. However, current quantitative evaluation methods often prioritize quantitative indicators such as the quantity and level of scientific research results, which may not fully reflect their real quality. Qualitative evaluation suffers from subjectivity, and can be influenced by factors like human relations and the Matthew effect. To address these limitations, this paper proposes a research performance evaluation model based on the BP model and analytic hierarchy process (AHP). simulation experiments were conducted to verify the model's effectiveness. The results showed that this model can significantly improve the evaluation speed and accuracy compared to other models, leading to better evaluation outcomes. By taking into account both quantitative and qualitative indicators, the proposed model provides a more comprehensive and objective evaluation of scientific research performance. It is expected to be useful for decision-makers in academic and research institutions, as well as researchers themselves, to identify strengths and weaknesses and optimize their research strategies. © 2023 IEEE.

The evolution of wireless communication technology is inextricably linked to the growing demand from consumers to connect multiple devices to the network. Massive multiple input multiple output (MIMO) is a new advancement compared to conventional communication systems, which use tens to hundreds of interconnected antennas that serve multiple user terminals at the same time and frequency. 5G's massive MIMO system performance degrades as a result of its extensive use of antennas;consequently, it is characterized by high complexity and wasteful energy consumption. The sum rate is an essential system performance parameter in 5G massive MIMO. Deep learning (DL) is utilized to advance and enable the maximum potential of 5G massive MIMO in order to increase the sum rate. DL can process, generate, and provide sophisticated analysis on virtually any given task, with concise and verifiable outcomes. Consequently, this paper analyzes the 5G massive MIMO sum rate using a deep neural network (DNN). The proposed DNN technique employs seven hidden layers per node (512, 256, 128, 128, 32, 5, and 6) and Relu activation. The aggregate rate was obtained by simulating the 5G massive MIMO system model with the DNN. The simulation results demonstrated that the DNN algorithm was able to produce a high sum rate value and is superior to conventional 5G massive MIMO. © 2023 IEEE.

With the widespread application of satellite communication systems and the explosive growth of mobile terminals, various demands have brought considerable pressure to the satellite communication system. There are many network stability and security issues in the satellite communication process, leading to the proposal of a non-cooperative game-based satellite network communication method. Both sides engage in non-cooperative games: during the attack and defense process of the satellite communication network, the attacking side exploits vulnerabilities in the satellite communication network system to maximize the attack effect, taking a series of attack actions to achieve a certain goal of disrupting the communication network system. The defense side, in response to the performance requirements of the satellite communication network system and the attacks it faces, takes a series of defense actions [3]. The antagonism, non-cooperation, and high degree of strategic dependence in communication network attacks and defenses are closely related to game theory. After the attack and defense process begins, the attacking side continuously adjusts the next round of attack strategy based on the attacks launched and the gains obtained, while the defense side, to maximize its own gains, will maintain smooth satellite network communication as much as possible based on the contract routing algorithm. © 2023 ACM.

AC/DC microgrids contain a large number of power electronic devices, and their frequent switching process will bring a huge amount of calculation to the electromagnetic transient simulation, thus reducing the simulation efficiency. The research on the external characteristics of the microgrid does not need to pay attention to the dynamic process inside the converter. Therefore, the equivalent simplification of mathematical model is used in this paper to reduce the amount of simulation calculation data of the electromagnetic transient model to achieve the purpose of improving simulation efficiency. This method is concise and efficient, which does not relay on the performance of computer or change the program algorithm of software. By simplifying the current loop with fast dynamic response in the control system, he time response capability of the model is improved, and the converter is replaced by a controlled voltage source, which reduces the dynamic process of frequent changes in the converter. Based on the mathematical equivalent simplified model of microgrid, an electromagnetic transient simulation model was established. Through simulation verification, the simulation efficiency can be significantly improved while the accuracy of the simulation results is guaranteed. © Published under licence by IOP Publishing Ltd.
