K. Zeyde, Alisa Vardugina
This article is based on the conclusion that the observability of small perturbations of an electrodynamic system may be a priori estimated at the stage of finite element mesh optimization. In this paper, an attempt has been made to generalize the formulation of the problem using mathematical perturbation theory, electrodynamic Mie theory, Rayleigh scattering, and computational methods of electrodynamics. In this work, we consider a certain calibration element, which is a sphere for which there is reliable solution, and on which we may check the hypothesis and requirements regarding the considered problem. Developed specific rules for objects decomposition into a computational mesh and its a priori control for conducting accurate modeling. Validation of the optimization technique was carried out by comparing the numerical data and experimental data. The objects of study are thin metal plate and metal spheres. The electrodynamic system is a well-studied conical dielectric antenna.

V. Kompaniets, A. Kazanskaya, A. Tselykh, Valery Grigoryev
The article describes a part of the ergonomic study of a mobile application user interface. It briefly presents the methodological review of the study, based on the of Schneiderman. This assessment was expanded by the GOMS-TLM method adapted for touch input and the eye tracking procedure on Tribe Eye Tracking equipment in the task of assessing the speed of a user interaction with an application. It has been demonstrated that the actual speed of the user, who is interacting with the test application for the first time, measured in eye tracking, is, on average, significantly lower than the prediction received by the GOMS-TLM method. It is higher the prediction for users familiar with the interface, however. Thus, in the work it was concluded that the GOMS-TLM method can give acceptable results that do not contradict the empirical oculographic experiment with minimal resource expenditure

An Empirical Study of Goal Setting in UX/UI-design UX/ ui设计中目标设定的实证研究
V. Kompaniets, A. Lyz, A. Kazanskaya
The article is devoted to the empirical experience of goal-setting research in the process of UX/UI design. The study was conducted on the basis of the master's program "Ergodesign of the user interface", implemented in the Institute of Computer Technologies and Information Security of the Southern Federal University in accordance with the relevant professional standard "Specialist in the design of graphic and user interfaces." The UX/UI-design module of this program is built according to the classical level system of elements by J. Garrett. The article considers filling the system level framework with a minimum set of specific methods and tools that have proved their effectiveness and didactic value. In this regard, it is very promising in the tasks of researching user experience, including its unconscious components, instrumental methods of oculography and electroencephalography are presented, which are now being implemented by relatively inexpensive and compact devices, in particular, Eye Tribe eye tracking and the NeuroSky MindWave neuro headset. The conclusion is made that G. Garrett’s system of elements is still of high practical importance as a visual goal-setting tool in the process of UX/UI design.

Machine Learning Approaches to Predict New Mobile Internet Customers 预测新的移动互联网客户的机器学习方法
Aktham Sawan, Rashid Jayousi
Globalization and liberalization of the economy dramatically shifted the nature of business competition. The emergence of new technology in business operations has intensified rivalry and generated new opportunities for service providers. In order to deal with increasing situations, businesses are turning their focus to maintaining current clients rather than acquiring new ones. This is more cost-effective and therefore needs fewer energy. In this article, future mobile internet customers are investigated on the basis of machine learning and deep learning strategies applied to consumer activity and usage knowledge, which can assist new mobile internet customers. This paper utilized consumer usage and similar knowledge from a telephone service provider to examine mobile internet customers in the telecommunications industry. XGBoost and Random Forest the decision tree ensembles are used as basic statistical machine learning models for the development of a binary mobile internet classifier. The implementation component was developed using Python, a state-of-the-art structured data processing platform for machine learning and data mining. Many ML and deep learning approaches such as (K-Nearest Neighbors KNN, logistic regression, Support Vector Machine SVM, and Deep Neural Network DNN) have been tested to achieve greater and more successful outcomes and results.
经济全球化和自由化极大地改变了商业竞争的性质。商业运作中新技术的出现加剧了竞争,并为服务提供商带来了新的机会。为了应对不断增加的情况,企业将注意力转向维持现有客户,而不是获取新客户。这种方法更具成本效益,因此需要更少的能源。在本文中,基于机器学习和深度学习策略应用于消费者活动和使用知识的基础上,对未来的移动互联网客户进行调查,以帮助新的移动互联网客户。本文利用消费者使用和类似的知识,从一个电话服务提供商来检查移动互联网客户在电信行业。使用决策树集成的XGBoost和Random Forest作为基本的统计机器学习模型来开发二进制移动互联网分类器。实现组件是使用Python开发的,Python是用于机器学习和数据挖掘的最先进的结构化数据处理平台。许多机器学习和深度学习方法,如(k近邻KNN,逻辑回归,支持向量机SVM和深度神经网络DNN)已经经过测试,以获得更大,更成功的结果和结果。

The role of blockchain for increase trust on software components and services 区块链在增加对软件组件和服务的信任方面的作用
Vaidas Giedrimas
Software components and services are the main building blocks for distributed software projects, enabling them to make software engineering really global. However, the trust for binary components or service is still an open question. Because the components and services are provided to the system without the possibility of the detailed inspection of its internals, global system integrators are walking on edge to approve such building blocks inside the system. In the times when software quality now is critically important (as the financial data), we need solutions as secure as those which are used to preserve financial data. In this paper, the authors discuss the main issues of the software components and services trust and to present the blockchain-based model of software metadata registration and retrieval to increase the trust for the software composition entities.
软件组件和服务是分布式软件项目的主要构建块,使它们能够使软件工程真正全球化。然而,对二进制组件或服务的信任仍然是一个悬而未决的问题。由于提供给系统的组件和服务没有对其内部进行详细检查的可能性,全球系统集成商正在紧张地批准系统内部的此类构建块。在软件质量现在至关重要的时代(就像财务数据一样),我们需要与用于保存财务数据的解决方案一样安全的解决方案。在本文中,作者讨论了软件组件和服务信任的主要问题,并提出了基于区块链的软件元数据注册和检索模型,以增加对软件组合实体的信任。

Ray tracing simulation of wing mirrors for ultrasonic sensor based blind spot monitoring system 基于超声传感器的盲点监测系统翼镜光线追踪仿真
J. Kholkhujaev, Nodirbek Abdurakhmonov, S. Ruzimov, N. Abdukarimov, J. Inoyatkhodjaev, Abdulla Saidov
In this paper, we propose a method for 3D virtual estimation of blind spot zone for passenger vehicle. Blind spot zone (BSZ) is the problem of inconspicuous area that accounts for majority part of lane change related accidents. To estimate BSZ, the wing mirror reconstruction with the driver's eyes as a focal point in the vehicle has been performed. Thus far, the reconstruction of mirrors and driver in the vehicle has been a problem since they are often based on approximations or inaccurate data. Our aim in this paper was to confirm that ray tracing simulation of mirrors can be performed in order to identify the BSZ.The virtual model of wing mirror and contiguous vehicle parts are created in Solidworks and TracePro to make ray tracing simulation. The research was limited to the range of 3600mm. Physical experiment set up is grid-based technique used to model BSZ and make comparative analysis with virtual mirror ray tracing simulation. Matlab is used to compare grid-based technique to identify BSZ and the simulated BSZ angle.Additionally, the paper discusses possibilities of using different sensor technique for blind spot monitoring systems (BSMs) for passenger vehicles. BSMs are often applied in driver assistant systems for autonomous vehicles with level one, while the paper discusses possibility of installing BSMs onto passenger cars with level 0 autonomy.In conclusion, ray tracing simulation of virtual wing mirror can be used to detect 3D BSZ and suggest a BSMs based on the data obtained from simulation. BSMs installment can be done on passenger cars with much cost effective way using the BSZ virtual analysis.
本文提出了一种乘用车盲区的三维虚拟估计方法。盲区(Blind spot zone, BSZ)是指在变道相关事故中占绝大部分的不显眼区域问题。为了估计BSZ,以驾驶员的眼睛作为车辆焦点进行了翼镜重建。到目前为止,车辆后视镜和驾驶员的重建一直是个问题,因为它们通常基于近似值或不准确的数据。我们在本文的目的是证实,射线追踪模拟的镜子可以进行,以确定BSZ。在Solidworks和TracePro软件中建立了汽车后视镜及相邻部件的虚拟模型,进行了光线追踪仿真。研究仅限于3600毫米范围内。物理实验设置采用网格技术对BSZ进行建模,并与虚拟镜像光线追踪仿真进行对比分析。利用Matlab对基于网格的BSZ识别技术和仿真BSZ角度进行了比较。此外,本文还讨论了在乘用车盲点监测系统(BSMs)中使用不同传感器技术的可能性。BSMs通常应用于一级自动驾驶汽车的驾驶员辅助系统中,而本文讨论了在0级自动驾驶乘用车上安装BSMs的可能性。综上所述,虚拟翼镜的光线追踪仿真可以用于检测三维BSZ,并根据仿真数据提出bsm。利用BSZ虚拟分析,可以以一种经济有效的方式在乘用车上安装bsm。

A new dataset for the detection of hand movements based on the SEMG signal 基于表面肌电信号的手部运动检测新数据集
Adilbek Turgunov, Kudratjon Zohirov, Bobur Muhtorov
in this article, we would like to present a new dataset (DS-dataset) designed to detect hand movements based on SEMG (surface electromyography) signal. This DS includes data from 42 healthy people and seven hand movements, which included three complete arm movements, i.e. punch, grip, finger touch, open hand, three-finger movements, i.e. flexion of the index finger, flexion of the middle finger, flexion of the ring finger, and one waiting state. This data was obtained using BTS's state-of-the-art Free-EMG 10-channel recorder. Based on the data in DS, the characteristic vector of the signal was generated, and were classified using classical classification algorithms (support vector machine - SVM, random forest - RF and k-nearest neighbor algorithm - k-NN). The presented DS can be used as a basis for determining the localization of electrodes and for detecting hand movements when receiving the SEMG correctly.

The presented DS can be used as a basis for determining the localization of electrodes and for detecting hand movements when receiving the SEMG correctly.","PeriodicalId":136491,"journal":{"name":"2020 IEEE 14th International Conference on Application of Information and Communication Technologies (AICT)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127890465","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}

Accident & Emergency Informatics : Terminologies and Standards are needed for Digital Health in the Early Rescue Chain 事故与应急信息学:早期救援链中的数字健康需要术语和标准
T. Deserno, R. Jakob
Recently, the World Health Organization (WHO) has released a draft of its Global Strategy on Digital Health 2020-2024. Accident & emergency informatics (A&EI) addresses these targets providing fully automatic and specific rescue calls, which are generated by smart implants, smart clothes, smart wearables, smart vehicles, smart homes, or the Internet of Things (IoT). These smart environments monitor unobtrusively and continuously environmental, behavioural, physiological, or psychological parameters. In near future, they will autonomously generate specific alerts on adverse (health) events. A&EI interconnects the information and communication technology (ICT) systems in the early rescue chain. It enables semantically interoperable information exchange by the International Standard Accident Number (ISAN). In this paper, we describe key ICT components of the early rescue chain: alarming, responding, and curing instances. We suggest a minimum dataset that contains an event identifier, time and location, the type of event, and the number of victims including – if available – their identity. Concerning location, we address navigation on static as well as dynamic sites, within buildings, and brute-force getting into vehicles. Here, there is a lack of international classifications, terminologies, and standards to support semantically interoperable information exchange in the early rescue chain without any humans in the loop.
近日,世界卫生组织(世卫组织)发布了《2020-2024年全球数字卫生战略》草案。事故与应急信息学(A&EI)针对这些目标,提供由智能植入物、智能服装、智能可穿戴设备、智能车辆、智能家居或物联网(IoT)生成的全自动和特定救援呼叫。这些智能环境不引人注目地持续监测环境、行为、生理或心理参数。在不久的将来,它们将自动生成针对不良(健康)事件的特定警报。A&EI将早期救援链中的信息和通信技术(ICT)系统互连起来。它通过国际标准事故编号(ISAN)实现语义上可互操作的信息交换。在本文中,我们描述了早期救援链的关键ICT组成部分:报警、响应和处理实例。我们建议建立一个最小的数据集,其中包含事件标识符、时间和地点、事件类型以及受害者人数,包括(如果可用)他们的身份。关于位置,我们解决了静态和动态站点、建筑物内的导航以及暴力进入车辆的问题。在这里,缺乏国际分类、术语和标准来支持早期救援链中语义上可互操作的信息交换,而没有任何人员参与。
