Research on Metaverse Technology-enabled Innovation Ecosystem
Get PDFTraditional innovation systems are facing new dilemmas and challenges, and there is an urgent need for digital technologies
to reduce investment risks and fuel technology transformation at scale. The metaverse, as an integrator of multiple emerging technologies,
brings new opportunities for the development of innovation systems as it provides a trusted platform for innovative companies and
organizations. The metaverse initially started as a game experiment that generated a new form of innovation in a virtual world with a
plethora of opportunities and capabilities. However, research on the issue of innovation entrepreneurship in the metaverse and the conceptual
framework its core technologies in this process is limited. In this paper,we construct the conceptual framework of the metaverse technologyenabled innovation ecosystem, and summarize the three phases of the metaverse innovation ecosystem towards maturity

explores the hybrid teaching mode of the course, and gives the corresponding teaching measures and assessment methods
Application analysis of intelligent robot numerical control technology in mechanical manufacturing
Get PDFunder the background of the new era, the innovation and development of science and technology promote the development
of all fi elds in the direction of intelligence, integration and informatization. At the same time, the fi eld of mechanical manufacturing has
achieved remarkable development results, but there is still room for the improvement of mechanical manufacturing capacity, which can
meet people’s production and living needs in the end. With the advent of the Internet of things era, the rapid development of science and
technology, the emergence of intelligent and digital technology, and plays a vital role in the fi eld of mechanical manufacturing. The wide
application of intelligent robot numerical control technology has greatly improved the effi ciency and quality of mechanical manufacturing,
which can provide basic equipment for the innovation and development of other fields. How to further analyze the application and
development of robot numerical control technology in the fi eld of mechanical manufacturing is an important issue for researchers to solve.
This paper will carry out in-depth exploration around this issue, in order to provide theoretical reference for researchers
Three-dimensional fi nite element analysis of the eff ects of diff erent attachments on molar distal displacement in invisible orthodontics
Get PDFObjective: The aim of this study was to establish a three-dimensional fi nite element model and use fi nite element analysis to
explore the eff ects of diff erent attachments on the distal movement of molars. Methods: Using Mimics, Geomagic Wrap, Soildworks, and
Ansys software, a three-dimensional fi nite element model of the mandible was established. According to the diff erences in the attachment
attached to the second molar, the model was divided into four groups for ex periment: A-Rectangular attachment(abbreviation:RA); B-Half
water drop shaped attachment 1(abbreviation:HWDA1); C-Half water drop shaped attachment 2(abbreviation:HWDA2); D-Double half
water drop shaped attachments set(abbreviation:DHWDAS). The distal movement of molar was analyzed by simulating the orthodontic
process of invisible appliance with diff erent loads.Results: The displacement patterns of all models were accompanied by diff erent degrees
of tilt. From the simulation results alone, the root control eff ect of half water drop attachment 2 was slightly better than that of half water
drop attachment 1 and double half water drop attachments set, but both were better than rectangular attachments. In terms of volume, the
volume of the double half water drop attachments set was signifi cantly smaller than the other three groups, and the root control eff ect was
also better. Conclusion: Comprehensively, when simulating the distal displacement of the second molar with clear aligner, the double half
water drop attachments set has more advantages

The results of this project will provide the theoretical basis and technical support for the development of digital twin technology in the field of water resources in China and contribute to the development of water resources in China
Accuracy Improvement of Fault Diagnosis Methods for Small Modular Pressurized Water Reactors Based on Machine Learning Methods
Get PDFThe paper proposes a fault diagnosis method for small modular pressurized water reactors (SMPWR). Due to the compactness and complexity of SMPWR, for general fault diagnosis methods, it is difficult to extract the corresponding special complex fault characteristics, resulting in a great increase in the difficulty of diagnosis. Therefore, this paper intends to propose a more applicable diagnosis method in close combination with the characteristics of SMPWR. Traditional machine learning methods based on feature selection and feature extraction work well in other research areas, but when it comes to SMPWR, it is difficult to determine the features that should be extracted, and different feature selection can cause great interference in the diagnosis results. Therefore, this project proposes to use advanced deep learning algorithms to automatically learn fault features of complex systems, reduce human interference, and build up more reasonable and accurate intelligent diagnostic models
Teaching Image Spectrum Based on Structured Light Illumination
Get PDFIn the past decade, structured lighting illumination technology has developed rapidly. It provides a convenient method for directly obtaining a single spectral component of an image. It is proposed in this paper that teaching image spectra through structured light lighting. Through image spectrum acquisition and image reconstruction, the relations between spatial and frequency domains are demonstrated vividly. Case teaching combined with group research is used to guide students to understand and process images in frequency domain
