The occurrence of hazardous gases and toxic or harmful vapors in laboratories, factories, and chemical warehouses requires a fast detection of leakage accidents to avoid health impairments. In this paper, the integration and validation of two novel metal oxide gas sensors (MOX) for the application in an IoT-based air quality monitoring and the alarming system is proposed. The sensors are combined with WeMos D1 Mini IoT-based microcontroller for data processing and transmitting via Wi-Fi communication protocol. The system design takes into consideration the low-cost, light-weight, small-size, and low power consumption concepts to enable a portable compact system that can be operated stand-alone or easily be adapted to any stationary or mobile robotic platform. The system was tested with several volatile organic materials (VOCs). The acquired air quality data are transferred to an IoT cloud, where the data are stored in a database for further analysis and research. Further, the data can be directly monitored on a PC, tablet, and smartphone. The system testing results confirm that the system can be used efficiently in laboratory environments.
在实验室、工厂和化学品仓库中发生危险气体和有毒或有害蒸气,需要快速检测泄漏事故,以避免对健康造成损害。本文提出了两种新型金属氧化物气体传感器(MOX)的集成和验证,用于基于物联网的空气质量监测和报警系统。传感器与WeMos D1 Mini iot微控制器相结合,通过Wi-Fi通信协议进行数据处理和传输。该系统设计考虑了低成本、轻重量、小尺寸和低功耗的概念,使便携式紧凑系统可以独立操作,也可以轻松适应任何固定或移动机器人平台。对该系统进行了几种挥发性有机物质(VOCs)的测试。获取的空气质量数据被传输到物联网云,数据存储在数据库中,供进一步分析和研究。此外,数据可以直接在PC、平板电脑和智能手机上进行监控。系统测试结果表明,该系统可以在实验室环境中高效使用。

This paper discusses an application of motion capture in longsword fencing, a discipline experiencing rising popularity since the 1990s. Historical European Martial Arts alliance focuses on re-enacting the Late Middle Ages and Renaissance fighting styles. To popularize this art, novel research to automatically distinguish selected sword cutting techniques has been conducted. The fencing knowledge required for conducting this research was based on publications and consultation with experts in the field, and recordings. For this research, different movements from Masterstrikes such as Zornhau (Strike of Wrath), Schielhau (Squinting Strike), Zwerchhau (Cross Strike), Krumphau (Crooked Strike), Scheitelhau (Crown Strike) were selected. Motions performed by an adept fencer (acting expert) were used as patterns of correct strikes and compared with the movements of fencing amateurs. The main goal of this research was to measure the precision of movement while performing five different fencing strokes. Each movement was recorded with 39 unique full-body plug-in gait configurations initially designed for medical applications. During the exercise, 16 EMG electrodes configuration was used for the measurement of muscle activity.
本文讨论了动作捕捉技术在20世纪90年代兴起的长剑击剑运动中的应用。历史上的欧洲武术联盟专注于重新制定中世纪晚期和文艺复兴时期的战斗风格。为了普及这门艺术,人们进行了一项新的研究,以自动识别选定的剑切技术。开展这项研究所需的击剑知识是基于出版物和咨询该领域的专家以及录音。在这项研究中,选择了来自大师打击的不同动作,如愤怒之击、斜视打击、交叉打击、弯曲打击、皇冠打击等。用熟练击剑运动员(表演专家)的动作作为正确击球的模式,并与业余击剑运动员的动作进行比较。这项研究的主要目的是测量在进行五种不同击剑动作时的运动精度。每个动作都记录了39种独特的全身插入式步态配置,最初是为医疗应用而设计的。在运动过程中,16个肌电图电极配置用于测量肌肉活动。

3D Registration of Multiple RGB-D Cameras on Arbitrary Position of a Symmetric Object with No Overlapping in a Meat Factory Environment 肉厂环境中多个RGB-D相机在对称物体任意位置无重叠的三维配准
I. de Medeiros Esper, L. E. Cordova-Lopez, P. From, A. Mason
This paper presents work relating to the reconstruction of 3D point clouds taken from cameras placed arbitrarily in pairs on either side of an object (a pig carcass in this specific use-case). This poses a challenge for complete object reconstruction since the two sides or halves of the object have little or no overlap and high degree of symmetry. The investigation was part of a data collection inside slaughterhouses for a meat factory cell concept development, where the production line cannot be stopped to perform calibration of the cameras. In addition, the footprint should be small, and the cameras' lenses protected and easy to clean. This work presents the method, or pipeline, used to overcome this challenge along with the performance of the pipeline by comparing real-world and point cloud distance measurements.
本文介绍了与3D点云重建相关的工作,这些点云是从任意成对放置在物体两侧的相机中获取的(在此特定用例中为猪胴体)。这对完整的物体重建提出了挑战,因为物体的两边或一半很少或没有重叠,并且高度对称。该调查是屠宰场内数据收集的一部分,用于肉类工厂细胞概念的开发,生产线不能停止以对摄像机进行校准。此外,占地面积应该小,相机的镜头保护和易于清洁。这项工作提出了一种方法,或管道,用于克服这一挑战,以及通过比较现实世界和点云距离测量的管道性能。

Better understandability of prediction models: a case study for data-based road safety management system 提高预测模型的可理解性:基于数据的道路安全管理系统案例研究
Viera Anderková, F. Babič
The road safety management system aims to ensure a safe transport system for all road users. Analyses of data about traffic accidents can provide important knowledge to support relevant decision-makers or processes. This fact motivated our case study covering the analytical process over publicly available data about traffic accidents in England, Scotland, and Wales. Based on our previous experience with this dataset, we aimed not on the prediction models and their accuracy, but on their explanations for the end-users with limited knowledge from data mining, machine learning, or artificial intelligence. For this purpose, we improved the generated decision models with selected explainable methods like The Local Interpretable Model-Agnostic Explanation (LIME) and SHap Additive exPlanations (SHAP) values. The final visualizations show which attributes and to what extent they contribute to each type of accident.
道路安全管理制度旨在确保所有道路使用者的安全运输系统。对交通事故数据的分析可以提供重要的知识,以支持相关的决策者或程序。这一事实促使我们对英格兰、苏格兰和威尔士的交通事故公开数据进行分析。根据我们之前对这个数据集的经验,我们的目标不是预测模型及其准确性,而是它们对数据挖掘、机器学习或人工智能知识有限的最终用户的解释。为此,我们选择了一些可解释的方法,如局部可解释模型不可知论解释(LIME)和SHap加性解释(SHap)值来改进生成的决策模型。最后的可视化显示了哪些属性以及它们在多大程度上导致了每种类型的事故。

Optimized Class Decomposition for Fault Detection 面向故障检测的优化类分解
S. Karakatič, D. Fister, Ömer Faruk Beyca, Iztok Fister
The paper proposes an innovative approach in solving the fault detection problem of sewerage treatment plant machinery. The proposed approach treats the fault detection data with the class decomposition problem, ensuring that a classification algorithm overlooks no disjunct instances. As the class decomposition technique requires heavy customization to each class of instances in every data set, Grey Wolf Optimizer is used to determine the appropriate clustering method with the appropriate setting for each class of instances. The proposed approach is tested on real-life sensor data from a sewerage treatment plant, and the results show that here proposed approach overshadows several manually proposed class decomposition methods.
本文提出了一种解决污水处理厂机械故障检测问题的创新方法。该方法利用类分解问题处理故障检测数据,保证了分类算法不会忽略不相交的实例。由于类分解技术需要对每个数据集中的每一类实例进行大量定制,因此使用Grey Wolf Optimizer为每一类实例确定具有适当设置的适当聚类方法。在污水处理厂的真实传感器数据上对所提出的方法进行了测试,结果表明所提出的方法掩盖了几种人工提出的分类分解方法。

F. Basçiftçi, L. M. Bokiye
Nowadays our life is becoming smart and simple with the help of smart and intelligent systems. The Internet of Things concept is enabling most digital devices to work cooperatively. In this article, we proposed a Library Management Automation system that is based on the Radio Frequency Identification (RFID) technology. The books and Students ID have RFID tags that are attached to them and hold information about books and students respectively. RFID readers used to read RFID tags attached to the books and students' IDs to do all tasks like the efficient and proper theft-controlled operation of libraries. This system will be connected to an RFID reader and printer. The main task of this system is to make work easy for users and librarians. Moreover, this system will be more user-friendly and easy. The proposed system reduces time and labor approximately from 70-80% after implementation.

Validation of a Self-developed Algorithm for Solving Inverse Problems on Impedance Networks 一种自行开发的求解阻抗网络逆问题算法的验证
Zoltán Vízvári, Nina Gyorfi, Mihály Klincsik, Zoltan Sári, Attila Tóth, P. Odry
Our research group examines a new aspect of the implementation of the Electrical Impedance Tomography (EIT) inverse problem solving method. As a result, the investigated material, which can be considered a continuum, is modeled as a linear network with concentrated parameters. In this article we managed to generalize the mathematical model that it also takes into account the dielectric constant of the material (the pair of concentrated parameters, i.e. the capacity). Thus, despite a significant increase in the number of unknowns in the model, we created an opportunity to apply a multi-frequency approach, as a result of which the optimized system of equations always remains overdetermined. After defining the mathematical model, for its validation, we created a physical model in order to reconstruct the resistance and capacitor values placed on the branches of the graph within their tolerance.
我们的研究小组研究了电阻抗断层成像(EIT)逆问题求解方法的一个新方面。因此,所研究的材料可以看作是一个连续体,被建模为一个具有集中参数的线性网络。在本文中,我们成功地推广了数学模型,它也考虑了材料的介电常数(一对集中参数,即容量)。因此,尽管模型中的未知数数量显著增加,但我们创造了应用多频率方法的机会,其结果是优化的方程系统始终保持超确定。在定义了数学模型之后,为了验证它,我们创建了一个物理模型,以便重建在其公差范围内放置在图分支上的电阻和电容值。

Clustering of Business Organisations based on Textual Data - An LDA Topic Modeling Approach 基于文本数据的商业组织聚类——一种LDA主题建模方法
Ferenc Tolner, M. Takács, G. Eigner, Balázs Barta
Textual data provides a new perspective and a huge potential with additional information in analysing and segmenting business organisations. Statistical “hard data” is often too general or even misleading and might be affected by several exogenous and endogenous factors while questionnaire or survey related “soft data” is hardly available or can be biased by the interviewees position in the organisation or by its own personal orientation. On the other hand, besides the aforementioned information sources business organisations, education- and research institutions etc. provide many times textual data on themselves as well, that can further contribute to the understanding of the investigated population. In this paper a topic modeling of 51 Central European business-, educational- and research organisation has been performed by Latent Dirichlet Allocation (LDA). The investigated organisations were partakers of an online survey where their textual organisational descriptions were collected together with basic geographical and industry related data. Based on the result a grouping of the stakeholders has been implemented and an LDA based methodology has been tested in order to further support cluster-forming efforts of business- and other type of organisations within the Central European region.
文本数据提供了一个新的视角和巨大的潜力,在分析和细分业务组织的附加信息。统计上的“硬数据”往往过于笼统,甚至具有误导性,可能受到几种外生和内生因素的影响,而问卷或调查相关的“软数据”很难获得,或者可能因受访者在组织中的职位或其个人取向而产生偏见。另一方面,除了上述信息来源,商业组织,教育和研究机构等也提供了很多次关于他们自己的文本数据,这可以进一步有助于了解被调查人群。本文利用潜在狄利克雷分配(Latent Dirichlet Allocation, LDA)对51个中欧商业、教育和研究机构进行了主题建模。被调查的组织是在线调查的参与者,他们的文本组织描述与基本的地理和行业相关数据一起收集。根据调查结果,对利益相关者进行了分组,并对基于LDA的方法进行了测试,以进一步支持中欧地区商业组织和其他类型组织的集群形成工作。

Based on the result a grouping of the stakeholders has been implemented and an LDA based methodology has been tested in order to further support cluster-forming efforts of business- and other type of organisations within the Central European region.","PeriodicalId":340545,"journal":{"name":"2021 IEEE 21st International Symposium on Computational Intelligence and Informatics (CINTI)","volume":"55 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113938705","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}

Contextual Integration of Activities in Virtual and Field Operating Cyber Physical Systems 虚拟和现场操作网络物理系统活动的上下文集成
L. Horváth
Work for this paper was motivated by the recognition that cooperation between engineering model system (EMS) representing cyber physical system (CPS) and cyber units of represented CPS is essential for both sides mainly to assist critical decisions. While EMS provides sophisticated model representations, procedures and much more for CPS, CPS acts as verified source of experience information to enhance models in EMS. This cooperation results theoretically grounded and, at the same time, experience proven representation fulfilling one of the essential current requirements against EMS. This paper contributes to methodology for the above connection mainly to enhance autonomous cooperation between EMS and the related cyber units of CPS. Cooperation between virtual and physical CPS configurations are analyzed using new organized scenario. Results of this analysis are applied at development concept and process to provide autonomous EMS (AEM) support for engineering in autonomous CPS. Following this, concept of model mediated research (MMR) is introduced to support research in engineering for AEM and CPS. Finally, experimental implementation of MMR concept in activity of the Virtual Research Laboratory (VRL) at the Doctoral School of Applied Informatics and Applied Mathematics (AIAMDI), Obuda University is discussed.
本文工作的动机是认识到代表网络物理系统(CPS)的工程模型系统(EMS)和代表CPS的网络单元之间的合作对于双方主要协助关键决策至关重要。虽然EMS为CPS提供了复杂的模型表示、过程和更多的东西,但CPS作为经过验证的经验信息来源,可以增强EMS中的模型。这种合作的结果在理论上是有根据的,同时,经验证明,代表满足当前对EMS的基本要求之一。本文主要是为加强EMS与CPS相关网络单位之间的自主合作,提供上述连接的方法论。通过新的组织场景,分析了虚拟CPS配置与物理CPS配置之间的协作关系。将分析结果应用于开发理念和流程,为自主CPS工程提供自主EMS (AEM)支持。在此基础上,引入了模型中介研究(MMR)的概念,以支持AEM和CPS的工程研究。最后,讨论了MMR概念在小布达大学应用信息学与应用数学博士学院虚拟研究实验室(VRL)活动中的实验实现。
