China has a large population, coupled with the rapid economic development in recent years, which promotes the rapid development of many industries; including the clothing industry is one of them. At present, China's clothing industry is well-known in the world, and also in the leading position in the world in terms of clothing consumption level. In recent years, the popularity of 3D printing technology has been very high, and it has been rapidly applied to many fields as soon as it came out. Now the technology has been gradually applied to the clothing industry. This paper selects two factories as experimental research object One factory applies 3D printing technology to its factory while the factory continue to adopt the original design method.

In order to use Midas GTS digital simulation to design high slope, it is necessary to calculate the stability analysis of the proposed structure. Stability analysis is an important tool in the field of structural engineering. It can be used for various purposes, such as determining the strength of columns and beams under different load conditions, calculating the deflection under different loads, and even checking whether the structure is safe enough before construction. The digital GTAs based slope stability analysis is performed using the Midas software. The stability analysis of high slope can be used to determine the stability state and behavior under different conditions. It consists of many steps. The first step is to define the geometric and material properties of each element, such as shape and size. These parameters are defined according to the design requirements. The second step is to calculate the force distribution of each element position in the 3D model.

In recent years, with the rapid development and wide application of modern information technology, the management environment and management concept of enterprises have been changed. The environment of enterprise accounting has changed greatly, and the accounting data system came into being. The application of accounting data system not only brings convenient and fast information services to enterprises, but also brings many security risks due to its own openness and the vulnerability of data storage media. With the expansion of the scope of use of computers, it is common to use computers for corruption, fraud and criminal activities. For example, the data stored on computer disks is easy to be tampered with; The data of the database is highly centralized, and unauthorized personnel may invade the enterprise's database through the computer network, browse all data files, copy, forge and destroy important data of the enterprise. Because computer crime has great concealment and harmfulness. Therefore, it is particularly important to strengthen the security of accounting data. This paper uses DES algorithm to encrypt accounting data.
近年来,随着现代信息技术的快速发展和广泛应用,企业的管理环境和管理理念发生了变化。企业会计环境发生了很大的变化,会计数据系统应运而生。会计数据系统的应用在为企业带来方便快捷的信息服务的同时,也因其自身的开放性和数据存储介质的脆弱性带来了诸多安全风险。随着电脑使用范围的扩大,利用电脑进行贪污、诈骗和犯罪活动已是司空见惯。例如,存储在计算机磁盘上的数据很容易被篡改;数据库的数据高度集中,未经授权的人员可能通过计算机网络侵入企业的数据库,浏览所有数据文件,复制、伪造和破坏企业的重要数据。因为计算机犯罪具有很大的隐蔽性和危害性。因此,加强会计数据的安全就显得尤为重要。本文采用DES算法对会计数据进行加密。

The structure of the traditional mechanical transmission is complex, and the dynamic performance of the system is influenced by many factors. Therefore, a new type of coaxial cylindrical magnetic coupling was designed in this paper, combined with the advantages of the magnetic coupling transmission. This design achieves the required torque transmission by reducing the volume of the prime mover and eliminating the transmission devices such as pulleys and mechanical gears. It realizes non-contact speed regulation drive, reduces vibration and noise, and overcomes the shortcomings of frequency conversion speed regulation.

With the continuous development of deep learning, how to use computer vision technology to accurately locate bolts and identify defects in complex natural backgrounds has become a common problem faced by both academia and industry. Aiming at the problems of slow detection speed and high false detection rate in current bolt defect detection, an improved Faster R-CNN bolt defect detection algorithm for transmission lines is proposed. First, with Faster R-CNN as the basic framework, through the experimental comparison of three different backbone networks, ResNeSt with higher detection accuracy is selected as the backbone network. Second, the feature extraction network and feature pyramid FPN structure are improved. Then, the improved Faster R-CNN model is trained on the transmission line bolt defect dataset. Finally, the application verification is carried out with the inspection on the transmission line above 110kV of a provincial power company. The results show that the method in this paper can assist the inspectors to quickly screen and locate the defective bolts in the high-resolution UAV image, thus greatly improving the inspection efficiency. Check work efficiency.

Throughout history, natural calamities have taken a toll on both property and life. Forest fires, hurricanes, floods, earthquakes, and tornadoes are all responsible for substantial damages, and often render access to the affected areas difficult. One of the challenges, particularly in remote areas, is accurately assessing the severity of the disaster. In this paper, we propose a solution to the challenge of determining the severity of property damage through the analysis building change within satellite imagery. We determine the severity of the loss by training deep neural networks to count buildings which were destroyed in multitemporal satellite imagery of the affected area. We demonstrate, through experimental results, that a model composed of a Single Shot Detector (SSD) and a Feature Pyramid Network (FPN) trained with Focal Loss is able to detect buildings through satellite imagery with improved performance compared to conventional object detection models. For evaluation, we use the xView dataset, which consists of high resolution satellite images containing building labels. We evaluate three different object detection models, namely: (i) SSD, (ii) Faster R-CNN (Regional-based Convolutional Neural Network), and (iii) SSD+FPN with Focal Loss. Our findings show that SSD+FPN with focal loss model achieves mAP improvements of 15% and 20% increase in detecting buildings in comparison to Faster R-CNN and standard SSD models, respectively. The improved mAP metric is a reflection of our more accurate detection and localization of buildings from remotely sensed imagery.
纵观历史,自然灾害对财产和生命都造成了巨大的损失。森林火灾、飓风、洪水、地震和龙卷风都是造成重大损失的原因,往往使人们难以进入受灾地区。其中一个挑战,特别是在偏远地区,是准确评估灾害的严重程度。在本文中,我们提出了一种解决方案,通过分析卫星图像中的建筑物变化来确定财产损失的严重程度。我们通过训练深度神经网络来计算受影响地区的多时相卫星图像中被摧毁的建筑物,从而确定损失的严重程度。我们通过实验结果证明,由单镜头探测器(SSD)和经过焦损训练的特征金字塔网络(FPN)组成的模型能够通过卫星图像检测建筑物,与传统的目标检测模型相比,性能有所提高。为了进行评估,我们使用xView数据集,该数据集由包含建筑标签的高分辨率卫星图像组成。我们评估了三种不同的目标检测模型,即:(i) SSD, (ii) Faster R-CNN(基于区域的卷积神经网络),以及(iii)具有焦损的SSD+FPN。我们的研究结果表明,与Faster R-CNN和标准SSD模型相比,具有焦损模型的SSD+FPN在探测建筑物方面分别实现了15%和20%的mAP改进。改进的mAP指标反映了我们从遥感图像中更准确地检测和定位建筑物。

Object Detection-Based Reinforcement Learning for Autonomous Point-to-Point Navigation 基于目标检测的自主点对点导航强化学习

Autonomous navigation has been a fundamental area of research for real-world mobile robotic applications, having widespread utility across many industries from warehouse package delivery to residential cleaning services. Because of the complex nature of the robot’s environment, several challenges have prevented effectively implementing reinforcement learning-based algorithms trained in simulation. While difficulties can arise from the virtual environment lacking the sophistication to represent such a large and complex state space based on data-heavy sensor observations, the variance in MDP representations across related studies biases their fair comparison, performance, and repeatability. In this study, it is found that the design of the reward function used for training a vision-based mobile agent to perform collision-free point-goal navigation in simulation plays a significant role in overall performance. A novel approach is introduced where reward is also granted for successfully detecting a target object scaled according to prediction confidence. This strategy was found to significantly improve the point-goal navigation behavior compared to simpler reward function designs seen in similar related studies.
自主导航一直是现实世界移动机器人应用的一个基本研究领域,在从仓库包裹递送到住宅清洁服务的许多行业都有广泛的应用。由于机器人环境的复杂性,一些挑战阻碍了在模拟中训练的基于强化学习的算法的有效实施。尽管虚拟环境缺乏复杂性,无法基于大量数据的传感器观察来表示如此庞大而复杂的状态空间,但相关研究中MDP表示的差异会影响它们的公平比较、性能和可重复性。本研究发现,用于训练基于视觉的移动智能体在仿真中进行无碰撞点目标导航的奖励函数的设计对整体性能起着重要作用。提出了一种新的方法,根据预测置信度对成功检测到目标物体给予奖励。与类似相关研究中发现的更简单的奖励功能设计相比,该策略显著改善了点目标导航行为。

Because of the complex nature of the robot’s environment, several challenges have prevented effectively implementing reinforcement learning-based algorithms trained in simulation. While difficulties can arise from the virtual environment lacking the sophistication to represent such a large and complex state space based on data-heavy sensor observations, the variance in MDP representations across related studies biases their fair comparison, performance, and repeatability. In this study, it is found that the design of the reward function used for training a vision-based mobile agent to perform collision-free point-goal navigation in simulation plays a significant role in overall performance. A novel approach is introduced where reward is also granted for successfully detecting a target object scaled according to prediction confidence. This strategy was found to significantly improve the point-goal navigation behavior compared to simpler reward function designs seen in similar related studies.","PeriodicalId":339737,"journal":{"name":"2022 World Automation Congress (WAC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128689533","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}
