To overcome the shortcomings of the quality evaluation of translation in the low-resource corpus, a cross-sentence pre-training model is proposed for English-Chinese translation. First of all, we provide an embedding technology to automatically adjust the position of words by using attention thought for reference. Then, the cross-layer language pre-training model is introduced into the reading efficiency test to solve the information sparsity caused by the low resource conditions of English. By regressing the sentence vector, the mechanical evaluation of translation quality is completed. The test results show that this model significantly improves the effectiveness of the evaluation of the quality of English-Chinese translation. Compared with the CEstmodel, the Pearson correlation coefficient of this algorithm has increased by 0.35, and the Spielbman correlation coefficient has increased by 0.15.

In this study, the human visual field test technology is established by using an optoelectrical system consisting of a translucent ellipsoid, an area light source, and a landscape scene with an indicator. During the test, the subjects stared at the indicator directly in front of them with one eye and kept their eyeballs still, scanning the light strip with peripheral vision and using the mouse button plus the playback program to record the start and end positions of the scanning light strip in the landscape scene. This method is tested subjectively, and the subject needs to respond during the test. Therefore, before the test, the subject needs to understand the test process and be trained in advance to improve the exam accuracy. In the experiment, fifteen subjects with normal vision and no eye disease were selected. Their visual fields were confirmed normal after a preliminary assessment. The test results showed that the subjects' eyes were within the normal visual field, indicating that this method was feasible. In this research, a digital optical platform for the near visual field is proposed to establish an optoelectric visual field measurement technology. The proposed method is characterized by small size, rapid operation, and easy portability. With the digital LCD and visual imaging technology, both dynamic and static visual fields can be tested. The test data on the eyes' upper, lower, nasal, and temporal sides were consistent with the normal visual field. This shows that this method is feasible and worthy of promotion in the optometry industry.
本研究利用半透明椭球、区域光源、带指示器的景观场景组成的光电系统,建立了人类视野测试技术。在测试过程中,被试用一只眼睛直视前方指示灯,眼球不动,用周边视觉扫描灯条,使用鼠标按键加上播放程序记录扫描灯条在景观场景中的开始和结束位置。这种方法是主观测试,在测试过程中需要受试者做出反应。因此,在考试前,考生需要了解考试流程,并提前进行培训,以提高考试的准确性。实验选取视力正常、无眼疾者15名。经初步检查,他们的视野正常。测试结果显示受试者的眼睛在正常视野范围内,说明该方法是可行的。本研究提出了一种近视场数字光学平台,建立了一种光电视野测量技术。该方法具有体积小、操作快捷、便于携带等特点。利用数字液晶显示和视觉成像技术,可以测试动态和静态视野。眼睛上、下、鼻、颞侧的测试数据与正常视野一致。说明该方法是可行的,值得在验光行业推广。

Aiming to solve the problem of the redundant manipulator, it is necessary to complete the trajectory-tracking with a fixed orientation in tasks. Therefore, we propose a manipulator end orientation control scheme based on a gradient projection algorithm. Firstly, according to the property of the redundant manipulator that realizes self-motion, the orientation control problem is transformed into the self-motion problem of the manipulator. The angle between the end-effector of the manipulator and each coordinate axis of the base coordinate system is optimized as the objective. Secondly, according to the expected orientation required by the task, the corresponding objective optimization function is designed and its gradient vector is calculated. Then, the expected orientation is taken as the target criteria, and a reasonable joint velocity adjustment function is designed. Finally, the scheme uses MATLAB simulation software to simulate the four-link manipulator and the six-degree-of-freedom manipulator, respectively. The experimental results show that the scheme is effective and feasible.
为了解决冗余机械手的问题,需要在任务中以固定的姿态完成轨迹跟踪。因此,我们提出了一种基于梯度投影算法的机械手末端姿态控制方案。首先,根据冗余机械手实现自运动的特性,将姿态控制问题转化为机械手的自运动问题;以优化机械臂末端执行器与基坐标系各坐标轴之间的夹角为目标。其次,根据任务所需的期望方向,设计相应的目标优化函数并计算其梯度向量;然后以期望方位为目标准则,设计合理的关节速度调节函数。最后,利用MATLAB仿真软件分别对四连杆机械臂和六自由度机械臂进行仿真。实验结果表明,该方案是有效可行的。

In order to enhance the risk control of private loans, a risk assessment technology of network loan projects based on multi-feature information and a risk-sensitive decision tree is provided. In this method, the credit conditions of the lender in the customer information submitted in the online loan system is first established and then combined with the lender's historical loan records, personal characteristics, and enterprise characteristics. The analysis method with the maximization under the ROC curve and the minimum mutual information are used to select the information set most relevant to the project risk analysis and with the minimum redundancy. Finally, the risk evaluation of loan enterprises is carried out by using the perfect risk-sensitive decision tree method. The test result shows that this method has better performance in private loan risk assessment compared with the existing methods.

Most schools often require youth students to receive essential skills in the 21st century as a basic requirement in daily life. Digital citizenship behaviors or digital literacy are relevant to each other and common as being essential in primary and secondary education. Although several curricula promote digital citizenship behaviors, students are still willing to study in a more enjoyable and proper learning environment with their preferences and current action. Game-based learning environment motivates students to learn with fantastic features, rewards, and active activities to enjoy learning. Scholars suggest that the story-telling or gaming scenario can enhance a well-design game-based learning environment if the students receive the opportunity to make and revise their decisions. The theory of making decisions through storyline telling is an application of the decision tree. However, the study efficiency of the decision tree in gaming scenarios needs to be verified. Thus, this study adopted a decision tree-based online gaming approach for assisting and adapting students in behaving good behaviors using digital tools. The results of pattern analysis for investigating the online gaming behaviors of the students indicate that those who followed the recommendations provided by the gaming approach had more positive digital citizenship behaviors, such as acting upstanders more often than bystander behavior.
大多数学校经常要求青年学生掌握21世纪的基本技能,作为日常生活的基本要求。数字公民行为或数字素养相互关联,在小学和中学教育中都是必不可少的。虽然一些课程提倡数字公民行为,但学生仍然愿意根据自己的喜好和当前的行动在一个更愉快、更合适的学习环境中学习。以游戏为基础的学习环境,以奇妙的功能、奖励和积极的活动激发学生的学习兴趣,享受学习的乐趣。学者们建议,如果学生有机会做出和修改他们的决定,讲故事或游戏场景可以增强设计良好的基于游戏的学习环境。通过故事情节进行决策的理论是决策树的一种应用。然而,决策树在博弈场景下的研究效率有待验证。因此,本研究采用基于决策树的在线游戏方法来帮助和适应学生使用数字工具的良好行为。对学生网络游戏行为的模式分析结果表明,那些遵循游戏方法建议的学生有更多积极的数字公民行为,如比旁观者更经常地表现出旁观者的行为。

In order to solve the difficulty in teaching chime bells, a virtual simulation was developed according to the requirements of course construction. This research reconstructed a set of virtual chimes and performances that were completely consistent with the shape, scale, and proportion of the chimes. Students conducted experiments such as tone recognition, solo, ensemble, solo, and ensemble creation through the way that “the left-hand keyboard controls the performance strength, and the right-hand mouse controls the performance speed and pitch”. The teaching effect showed that the experiment broadened the depth of traditional music teaching, improved students' learning enthusiasm and initiative, extended students' learning time and learning space, and cultivated students' collaborative interaction ability and cooperative innovation spirit.

Augmented reality (AR) is a technology that instantly merges digital pictures with the real scene. The perspective near-eye display is a key module of AR, through which computer-generated pictures or videos can be displayed in the existing environment. The purpose of this research is to establish the system structure of an augmented reality near-eye display device and to design the off-axis two-piece reflective aspherical mirror. Because AR glasses are wearable and are worn close to the eyes, not only the optical performance of the display but also the clear vision of the user needs to be considered. In this study, an off-axis two-piece reflective aspherical mirror is used as the optical system of the AR for displaying the digital image. The micro-display is placed at the focal point of the optical system to form a digital image, and the horizontal movement of the micro-display along the optical axis is controlled by a precise displacement mechanism so that the patient with uncorrected myopia or hyperopia can see the digital picture and real scene. Because the right and left micro-displays move horizontally independently, the user can see the images on the AR device, which becomes the biggest feature of this study.
增强现实(AR)是一种将数字图像与真实场景即时融合的技术。透视近眼显示是AR的关键模块,通过它可以在现有环境中显示计算机生成的图片或视频。本研究的目的是建立增强现实近眼显示设备的系统结构,并设计离轴两片式反射非球面反射镜。由于AR眼镜是可穿戴式的,佩戴时距离眼睛很近,因此不仅需要考虑显示器的光学性能,还需要考虑用户的清晰视觉。本研究采用离轴两片式反射非球面反射镜作为AR的光学系统,用于显示数字图像。微显示器放置在光学系统的焦点处形成数字图像,微显示器沿光轴的水平运动由精密位移机构控制,使未矫正近视或远视的患者能够看到数字图像和真实场景。由于左右微显示器水平独立移动,用户可以看到AR设备上的图像,这成为本研究的最大特点。

The perspective near-eye display is a key module of AR, through which computer-generated pictures or videos can be displayed in the existing environment. The purpose of this research is to establish the system structure of an augmented reality near-eye display device and to design the off-axis two-piece reflective aspherical mirror. Because AR glasses are wearable and are worn close to the eyes, not only the optical performance of the display but also the clear vision of the user needs to be considered. In this study, an off-axis two-piece reflective aspherical mirror is used as the optical system of the AR for displaying the digital image. The micro-display is placed at the focal point of the optical system to form a digital image, and the horizontal movement of the micro-display along the optical axis is controlled by a precise displacement mechanism so that the patient with uncorrected myopia or hyperopia can see the digital picture and real scene. Because the right and left micro-displays move horizontally independently, the user can see the images on the AR device, which becomes the biggest feature of this study.","PeriodicalId":176611,"journal":{"name":"2023 IEEE 6th Eurasian Conference on Educational Innovation (ECEI)","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134325593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the historical and cultural resources and the natural resource, the local cultural characteristics of the three rivers and six banks were analyzed from three aspects: cultural space as the material carrier of culture, the cultural industry as the carrier of cultural economy, and cultural activities as the carrier of cultural time. From the perspective of contemporary cultural transformation and postmodern cultural theory combined with the qualitative analysis of cultural variable models, comprehensive observation and judgment were carried out to propose the overall positioning of three rivers and six banks' cultural tourism development and the characteristic positioning of town streets. The town street cultural creative product system and development guidelines were provided as a basis for the implementation of integrated cultural tourism development in the three rivers and six banks area. The Delphi method and Fuzzy Logic Theory were used to establish a multi-attribute decision-making model. The result provides an objective quantitative analysis result for the establishment of cultural and creative products.
