Empowering high-speed train positioning: Innovative paradigm for generating universal virtual positioning big data

<abstract><p>High-speed trains (HSTs) positioning is a critical technology that affects the safety and operational efficiency of trains. The unique operating environment of HSTs, coupled with the limitations of real data collection, poses challenges in obtaining large-scale and diverse positioning data. To tackle this problem, we introduce a comprehensive method for generating virtual position data for HSTs. Utilizing virtual simulation technology and expert expertise, this method constructs a HST operating simulation environment on the Unity 3D platform, effectively simulating a range of operating scenarios and complex scenes. Positioning data is collected using virtual sensors, while error characteristics are incorporated to emulate real data collection behavior. The contribution of this paper lies in providing abundant, reliable, controllable and diverse positioning data for HSTs, thereby offering novel insights and data support for the evaluation and optimization of positioning algorithms. This method is not only applicable to various routes and scenarios, but also delivers fresh perspectives on data generation for research in other domains, boasting a broad scope of application.</p></abstract>

Archaeological and digital restoration of straight-front robe of Mawangdui Han Dynasty Tomb based on 3D reverse engineering and man-machine interactive technologies

Based on 3D reverse engineering and man-machine interactive technologies, this paper completed the pattern development of a straight-front robe of the Mawangdui Han Dynasty tomb and restored the straight-front robe by virtual simulation technology. Firstly, the garment contour was extracted from the straight-front robe image of the Mawangdui Han Dynasty tomb, and then the garment model was established in the 3D virtual environment. According to the style characteristics of the straight-front robe, the structural curves were drawn on the adjusted 3D robe surface, and the different curved surfaces formed by these curves were expanded to obtain 2D garment patterns. Finally, the unfolded patterns were stitched on the virtual human body to realize the digital restoration of the straight-front robe of the Mawangdui Han Dynasty tomb. Compared with the current methods of garment restoration, the method proposed in this paper not only reduces the technical requirements of pattern-making for archaeologists but also for unearthed cultural relic garments, the final pattern can be obtained without consulting a lot of data and repetitive modification of pattern, to improve efficiency and save manpower. Our proposed technology provides a new practical method for costume archaeology and restoration.

Effect analysis of a virtual simulation experimental platform in teaching pulpotomy

BackgroundThe experimental teaching of pediatric dentistry is a bridge between theoretical study and clinical practice, and virtual simulation technology provides a new method of instruction.MethodsWe built an experimental teaching platform using virtual simulation technology for vital pulpotomy that includes learning and examination modes. A total of 199 students majoring in stomatology in the fourth year at Sun Yat-Sen University were randomly divided into a control group (conventional teaching mode) and an experimental group (virtual simulation experimental teaching model). The teaching effect was evaluated by theoretical and experimental examination.ResultsWe found that both the theoretical and experimental scores of the experimental group were higher than those of the control group, and the theoretical scores of the experimental group after exposure to the virtual simulation experimental teaching platform were also higher than those before the class, with significant differences (P < 0.05). Feedback from the experimental group after the class indicated that the platform reinforced their theoretical knowledge and greatly improved their mastery of operational skills.ConclusionsThe application of a virtual simulation experimental teaching platform can effectively improve the teaching of pulpotomy.

Research on experiment teaching of anthropometry and virtual clothing design based on Gagné information processing theory

With the promotion of education informatization in colleges and universities, virtual simulation technology is increasingly used in experimental teaching. In the teaching of fashion-related majors, virtual simulation technology can help students quickly and efficiently understand design theories, which are difficult for them to understand. However, due to the complexity of the virtual simulation experiment, it is difficult for students to master all the techniques required for the operation of the experimental system in a short time. In traditional teaching, students passively accept knowledge taught by the teacher and follow the teacher's operation, thereby affecting the learning effect. Such teaching and learning process cannot fully functionalize students' sensory system coding, and therefore cannot form long-term memory. To optimize the application of virtual simulation technology in the teaching of fashion-related majors, this paper proposes a clothing virtual simulation experimental teaching method based on Gagné information processing theory. To verify its effectiveness, anthropometry and virtual clothing design experiment was adopted as the research object. Two groups of students were involved in the experiments. One group was taught traditionally while another group was taught by the Gagné information processing mode. Through a set of learning and teaching process evaluation, experiment results demonstrated that Gagné information processing mode can effectively help students to fine-process the knowledge they have learned, so that important information can be extracted and encoded to form long-term memory. This paper provides support for future Gagné information processing theory in the teaching of virtual simulation courses and exercises.

Avatar and distance simulation as a learning tool - virtual simulation technology as a facilitator or barrier? A questionnaire-based study on behalf of Netzwerk Kindersimulation e.V.

Virtual simulation modalities have been implemented widely since the onset of the severe acute respiratory syndrome coronavirus 2 pandemic restrictions in March 2020, as educators face persistent restrictions to face-to-face education of medical students and healthcare professionals.There is paucity of published data regarding the benefits and barriers of distance and avatar simulation training modalities. Following a 2-day virtual pediatric simulation competition facilitated by Netzwerk Kindersimulation e.V., using remote human avatars and distance simulation, we conducted a multicenter survey to explore the advantages and challenges of avatar and distance simulation among participants. We used a modified Delphi approach to draft and develop the 32-item online questionnaire with 7-point Likert-like scales (7 being the highest rating). Twenty participants answered our questionnaire. Respondents indicated both a high overall satisfaction (median of 5.0 [Q25-Q75: 4.0-6.0] ) for avatar and distance simulation 6.0 (5.0-6.0), respectively, as well as a high achieved psychological safety with both simulation types (5.0 [4.0-6.0] vs. 5.0 [4.0-6.0]). The most frequently reported profits of avatar and distance simulation included the elimination of travel distances, associated lower costs, less time spent attending the education activity, and effective communication and leadership training, especially with avatar simulation. Most often named challenges were technical problems, limited reception of non-verbal cues and a spatial distance from the team/educator. Based on the results of this pilot study, avatar and distance simulation can be employed successfully and appear to be good supplements to face-to-face simulation. Other studies are warranted to further explore the effectiveness of various types of virtual simulation compared to conventional presential simulation. We suggest using avatar-based simulation for targeted communication and leadership skills training and the application of distance simulation to bring simulation experts virtually to remote places where educator resources are lacking.

The results of the data analysis show that the satisfaction and willingness to continue to participate in the virtual simulation competition play a good role.

Art Design Teaching Based on the Multidata Fusion Algorithm and Virtual Simulation Technology

Virtual Reality (VR) technologies are widely applied to teaching art design. VR has been created with high-level techniques that create the artificial environment to support virtual aesthetics. Especially ceramics art design requires technical advancement to enhance business individuals. However, the user requires the virtual reality experience to improve the art design teaching performance. During the teaching process, reality learning patterns, experiences, and fusion ceramic product design are required to enhance art design teaching. So, in this research, modern art design has been optimized using virtual reality with a deep learning architecture for craftsmanship, style, ideals, creative aesthetics, cultural ramifications, and inherited designers to create an effective model. The deep learning-assisted gate array algorithm (GAA) is used to optimize the modern art structure in system design. Therefore, this approach reveals some experimental findings that produce better performance benefits than saving time and resources in traditional manual detection systems.
