Energy-saving and faster manufacturing techniques are essential requirements for the ideal production of polyethylene terephthalate (PET) bottles. The establishment of accurate calculation skills strengthens a quality working environment for improving manufacturing technology. We applied the adaptive finite element method and calculated the time-dependent SST (shear stress transport), k-ω, k-ε and LES (large eddy simulation) models to predict the airflow field around the PET bottles in a heating box. The computation of the flow field was performed using software COMSOL 5.5 (COMSOL Inc., Palo Alto, CA). The experimental data are acquired to compare with simulation results in terms of calculation accuracy. Computational fluid dynamics (CFD) results showed that error for the velocity and pressure of the flow field at specific positions in the vicinity of the preform was satisfied. The error estimation on the main physical quantity helps calculate other physical quantities. The variation trend of y+ values near the bottle surface had an identical trend alongside the gird concentration trend during the adaptive computation process. This study reveals that the outcome of the adaptive computation method and its underlying theories satisfy the physical requirements in this case.
节能和更快的制造技术是理想生产聚对苯二甲酸乙二醇酯(PET)瓶的基本要求。建立精确的计算技能,为提高制造技术加强了优质的工作环境。采用自适应有限元法,计算了随时间变化的SST(剪切应力输运)、k-ω、k-ε和LES(大涡模拟)模型,对加热箱中PET瓶周围的气流场进行了预测。流场计算使用COMSOL 5.5软件(COMSOL Inc., Palo Alto, CA)进行。获取了实验数据,并与仿真结果进行了精度比较。计算流体动力学(CFD)结果表明,在预制棒附近的特定位置,流场的速度和压力是可以满足误差的。对主要物理量的误差估计有助于计算其他物理量。自适应计算过程中,瓶面附近y+值的变化趋势与网格浓度变化趋势一致。研究表明,自适应计算方法及其基础理论的结果满足了这种情况下的物理要求。

More and more people cluster in major cities and thus causing urbanization challenges. In this scenario, many cities are employing technologies to lessen the impact on the environment and increase productivity and efficiency to cope with the high demand. Among which, smart transportation is essential in fulfilling the mobility in the urban areas and promising to meet the increasing demand of passengers. IoT application in a smart parking system has been facilitated in various ways. To achieve its full potential, we need to understand the associated issues and principals. Therefore, this paper focus on understanding the principals within IoT, the process for the layers to function in vehicle detection, and introducing different IoT sensors empowered by different technologies, including cloud computing, big data, RFID, and WSN, that facilitate the smart parking system. After assessing the potential use cases of the IoT in the vehicle presence detection of the smart parking system, this paper will identify and discuss the benefits and challenges along with the recommendation and consideration that serve as the manual to help the industries and the governmental institutions to select appropriate sensors according to different scenarios.

In modern life, it is a good choice to stay overnight in the hotels or Inns for a business or a short trip in a busy schedule. Today, most of the current hotel check-in and -out registration procedures still need to be completed by the counter service staff by contacting the hotel guest. However, the current registration procedure is not private for customers who put great importance on privacy and security. To protect customer privacy and personal information, contacting people should be reduced, and the transmission of customer personal data must be encrypted and avoided. For the business and security service of a high-level hotel to attract more customs, the best choice is to provide an electronic counter which provides customers with automatic check-in and out registration procedures. However, personal IDs resulting are required to successfully perform personal identification or authentication. Hence, this paper proposes a log-in system with automatic identification which detects the unique characteristics of the customer through the backend system verification and comparison. The system achieves the purpose of successful identification of individuals without carrying mobile devices and IDs and enables contactless check-in and -out registration procedure for assuring customer privacy and security.
在现代生活中,在繁忙的工作或短途旅行中,在酒店或客栈过夜是一个很好的选择。今天,目前大多数酒店的入住和退房登记手续仍然需要由柜台服务人员通过联系酒店客人来完成。然而,对于注重隐私和安全的客户来说,目前的注册程序并不私密。为了保护客户隐私和个人信息,应该减少接触人员,并且必须加密和避免客户个人数据的传输。高级酒店的商务和保安服务要想吸引更多的海关,最好的选择是提供一个电子柜台,为顾客提供自动的入住和退房登记程序。但是,成功执行个人识别或身份验证需要生成个人id。因此,本文提出了一种具有自动识别功能的登录系统,通过后端系统的验证和比对,检测出客户的独特特征。该系统实现了在不携带移动设备和身份证的情况下成功识别个人身份的目的,并实现了非接触式入住和退房登记程序,确保了客户的隐私和安全。

Eye-tracking Data for Weakly Supervised Object Detection 弱监督目标检测的眼动追踪数据

We propose a weakly supervised object detection network based on eye-tracking data. A large number of training samples cannot be used due to the following problems: (1) the labels of training samples in object detection are not all pixel-level and (2) the cost of labeling is too high. Thus, we introduce a framework whose input combines images with only image-level labels and eye-tracking data. Based on the position given by the eye-tracking data, the framework has effective performance even in the case of incomplete sample annotation. Thus, we use an eye-tracker to collect the data on the most interesting area in the sample images and present the data in the fixations way. Then, the bounding boxes produced by the fixations data and the original image-level label become the input data of the object detection network. In this way, eye-tracking data helps us selecting the bounding boxes and providing detailed location information. Experiment results verify that the framework is effective with the support of eye-tracking data.
提出了一种基于眼动追踪数据的弱监督目标检测网络。由于以下问题,大量的训练样本无法使用:(1)目标检测中训练样本的标签并非都是像素级的;(2)标记成本太高。因此,我们引入了一个框架,其输入仅结合图像级标签和眼动追踪数据的图像。基于眼动数据给出的位置信息,该框架在样本标注不完全的情况下仍具有有效的性能。因此,我们使用眼动仪来收集样本图像中最有趣的区域的数据,并以注视的方式呈现数据。然后,由注视数据和原始图像级标签产生的边界框成为目标检测网络的输入数据。通过这种方式,眼动追踪数据可以帮助我们选择边界框并提供详细的位置信息。实验结果验证了该框架在眼动追踪数据支持下的有效性。

Simulation models are used during the entire life cycle of a factory. Because of a factory’s complexity, different simulation tools with different scope emerged over time. The holistic mapping requires coupled simulations that consider the factory from different perspectives. Each simulation requires a new tool and simulation model, which, up to now, has usually been created manually. This paper presents an analysis of existing approaches and data models for factory simulation description. These approaches allow data exchange between single simulation models, but do not provide dynamic coupling and model generation, and often cannot include all relevant information for the factory simulation. To achieve a continuous and comprehensive factory simulation, a concept for a metamodel for factory simulation description is outlined. Its goal is not only to describe a skeleton of the factory and provide simulation coupling and data exchange but also to provide a dynamic model generation.
仿真模型用于工厂的整个生命周期。由于工厂的复杂性,随着时间的推移,出现了不同范围的不同模拟工具。整体映射需要从不同角度考虑工厂的耦合模拟。每次仿真都需要一个新的工具和仿真模型,到目前为止,这些工具和模型通常都是手工创建的。本文分析了工厂仿真描述的现有方法和数据模型。这些方法允许在单个仿真模型之间交换数据,但不提供动态耦合和模型生成,并且通常不能包括工厂仿真的所有相关信息。为了实现连续、全面的工厂仿真,提出了工厂仿真描述元模型的概念。它的目标不仅是描述工厂的框架,提供仿真耦合和数据交换,而且还提供动态模型生成。

3D games have become popular in recent years. However, it is easy to produce a symptom when playing games, called 3D discomfort or motion sickness. The current explanations mostly focus on the authenticity of the game or the differences in the physiological level of the viewer. There is a rare discussion about whether the game causes human visual and brain discomfort which are caused by the 3D game production process. As many people feel uncomfortable with 3D games, the players gradually lose enthusiasm for the game. This study aims to understand motion sickness through the experiment and confirm that the field of view and viewing distance causes motion sickness through data collection. The experiment in this study has open and closed scenarios for psychological and physical tests. In the experiment, the players determine the most comfortable and uncomfortable vision and distance. The responses using a questionnaire are collected and analyzed in the online community. Based on the data, we test whether motion sickness occurs in different scenarios. The result helps prevent motion sickness in the game and allows players to enjoy the game. The result also provides basic data to prevent motion sickness in the game.
近年来,3D游戏变得非常流行。然而,在玩游戏时很容易产生一种症状,称为3D不适或晕动病。目前的解释主要集中在游戏的真实性或观看者生理水平的差异上。关于游戏是否会引起人类视觉和大脑的不适,这是3D游戏制作过程中引起的罕见讨论。由于很多人对3D游戏感到不舒服,玩家逐渐失去了对游戏的热情。本研究旨在通过实验了解晕动病,并通过数据收集确认视野和观看距离导致晕动病。本研究的实验分为开放和封闭两种场景进行心理和生理测试。在实验中,玩家确定最舒适和最不舒服的视野和距离。使用问卷的回答在在线社区中收集和分析。根据这些数据,我们测试了晕动病是否会在不同的情况下发生。其结果有助于防止游戏中的晕动病,并让玩家享受游戏。这一结果也为预防游戏中的晕动病提供了基础数据。

In this paper, a detrended fluctuation analysis (DFA) method is applied to assess the depth of anesthesia. General assessment of the depth of anesthesia (DoA) method is monitoring the cerebral cortex activity. The purpose of this study is to develop a new index which is different from the cerebral cortex activity monitoring index. Forty surgery patients (25 males + 15 females) were investigated. For every patient, the procedure is divided into three stages, before surgery 5 minute (stage A), during the surgery (stage B) and after the surgery 5 minute (stage C). The DFA values of each patient were calculated, and the mean ± standard deviation of DFA in 40 patients were calculated. Calculated results show that patients before surgery α, α1 and α2 values were 0.795 ± 0.188, 0.862 ± 0.165 and 0.839 ± 0.200, during surgery were 0.696 ± 0.353, 0.650 ± 0.107 and 0.690 ± 0.215, and after surgery were 0.803 ± 0.195, 0.871 ± 0.172 and 0.846 ± 0.209. The results have been shown significant differences (P < 0.05) in α and α2 values (including stages A and B, stages A and C) and none significant difference in α1 value (any two stages combination A, B and C). Therefore, the value of α and α2 have index effect in distinguish the physiological characteristics of patients before and after anesthesia.
本文采用非趋势波动分析(DFA)方法对麻醉深度进行评价。麻醉深度综合评价(DoA)法是监测大脑皮层的活动。本研究的目的是开发一种不同于大脑皮层活动监测指标的新指标。共调查40例手术患者(男25例,女15例)。将每例患者的手术分为术前5分钟(A期)、术中5分钟(B期)、术后5分钟(C期)三个阶段,计算每例患者的DFA值,并计算40例患者的DFA均值±标准差。计算结果显示,患者术前α、α1、α2值分别为0.795±0.188、0.862±0.165、0.839±0.200,术中α、α1、α2值分别为0.696±0.353、0.650±0.107、0.690±0.215,术后α、α1、α2值分别为0.803±0.195、0.871±0.172、0.846±0.209。结果显示α和α2值(包括A期和B期、A期和C期)差异有统计学意义(P < 0.05), α1值(A、B、C任意两个阶段的组合)差异无统计学意义(P < 0.05),可见α和α2值对区分麻醉前后患者的生理特征有指标作用。

General assessment of the depth of anesthesia (DoA) method is monitoring the cerebral cortex activity. The purpose of this study is to develop a new index which is different from the cerebral cortex activity monitoring index. Forty surgery patients (25 males + 15 females) were investigated. For every patient, the procedure is divided into three stages, before surgery 5 minute (stage A), during the surgery (stage B) and after the surgery 5 minute (stage C). The DFA values of each patient were calculated, and the mean ± standard deviation of DFA in 40 patients were calculated.

This research combines Raspberry Pi with the Internet of Things and the foundations of artificial intelligence to develop a real-time smart home surveillance system to improve safety at home. With a remote control method, people may check the safety of their own home in real-time. The realized smart system is based on Raspberry Pi 4B that adopts the Internet of Things architecture and combines several sensors and devices for home security to set up a safer home environment. The main method is to connect the Raspberry Pi to a network sharer or computer with a fixed IP and then input it into a computer or mobile phone to achieve remote control. To provide home safety for the elderly or the challenged people, the proposed system combines a voice control module to improve the user convenience.
