The methodological features of using software systems for modeling the dynamics of mechanical systems for solving educational research problems are considered. The traditionally established approach to studying the foundations of modeling the dynamics of technical systems is largely based on mastering the corresponding mathematical tools. With regard to modeling the dynamics of systems of solids, the mentioned approach involves, first of all, the development of skills in the preparation of ordinary differential equations (ODEs). At the same time, the formation of a mechanical calculation scheme as an «object of application of mathematics» becomes a natural stage of mathematical research, and the selection of simplifying assumptions that allow one or another idealization to correspond to a real object is carried out consciously taking into account the desire for certain internal properties of the mathematical model (for example, type and order of the ODE system). An important feature of modern systems for modeling the dynamics of solid’s systems is the ability to describe the object under study directly in terms of the subject area. This feature provides an increase in the effectiveness of modeling in solving design and engineering and scientific research problems and allows you to save a qualified specialist from a laborious routine. At the same time, as experience shows, in the process of solving educational and research problems, due to the mentioned features of modern software, students have certain difficulties in mastering the fundamental conceptual base of the corresponding discipline (physics, electrical engineering, theoretical mechanics, theory of automatic control, fundamentals of computer aided design). The article gives an example of an educational research task focused on overcoming these difficulties.
使用软件系统对机械系统的动力学进行建模以解决教育研究问题的方法学特征被考虑。研究技术系统动力学建模基础的传统方法主要基于掌握相应的数学工具。关于固体系统的动力学建模,上述方法首先涉及到常微分方程(ode)制备技能的发展。与此同时,作为“数学应用对象”的机械计算方案的形成成为数学研究的一个自然阶段,选择简化假设,允许一个或另一个理想化对应于真实对象,是有意识地考虑到对数学模型某些内部属性的渴望(例如,ODE系统的类型和顺序)。现代系统对固体系统动力学建模的一个重要特征是能够直接根据主题领域描述所研究的对象。该功能提高了建模在解决设计、工程和科学研究问题方面的有效性,并允许您从繁重的例行工作中节省合格的专家。同时,经验表明,在解决教育和研究问题的过程中,由于现代软件的上述特点,学生在掌握相应学科(物理学、电气工程、理论力学、自动控制理论、计算机辅助设计基础)的基本概念基础方面存在一定的困难。本文给出了一个教育研究任务的例子,重点是克服这些困难。

Our posture shows an impact on health both mentally and physically. Various methods have been proposed in order to detect different postures of a human being. Posture analysis also plays an essential role in the field of medicine such as finding out sleeping posture of a patient. Image processing based and sensor based approach are the leading posture analysis approaches. Sensor based approach is used by numerous models to focus on posture detection in which the person needs to wear some particular devices or sensors which is helpful in cases such as fall detection. Image processing based approach helps to analyze postures such as standing and sitting postures. Fitness exercises are exceptionally beneficial to individual health, but, they can also be ineffectual and quite possibly harmful if performed incorrectly. When someone does not use the proper posture, exercise mistakes occur. This proposed application utilizes pose estimation and detects the user’s exercise posture and provides detailed, customized recommendations on how the user can improve their posture. A pose estimator called OpenPose is used in this application. OpenPose is a pre trained model composed of a multi-stage CNN to detect a user’s posture. This application then evaluates the vector geometry of the pose through an exercise to provide helpful feedback. Pose estimation is a method in which spatial locations of key body joints is calculated using image or video of the person. This computer vision technique detects human posture in images or videos and shows the keypoints such as elbow or knee in the output image.
我们的姿势对身心健康都有影响。为了检测人体的不同姿势,已经提出了各种方法。姿势分析在医学领域也发挥着重要的作用,如找出病人的睡眠姿势。基于图像处理的方法和基于传感器的方法是主要的姿态分析方法。基于传感器的方法被许多模型用于关注姿势检测,在这种情况下,人需要佩戴一些特定的设备或传感器,这在跌倒检测等情况下很有帮助。基于图像处理的方法有助于分析站立和坐姿等姿势。健身运动对个人健康特别有益,但如果做得不正确,它们也可能是无效的,甚至可能是有害的。当一个人没有使用正确的姿势时,就会出现运动错误。这个拟议的应用程序利用姿势估计和检测用户的运动姿势,并提供详细的,定制的建议,用户如何改善他们的姿势。在这个应用程序中使用了一个名为OpenPose的姿态估计器。OpenPose是一个由多阶段CNN组成的预训练模型,用于检测用户的姿势。然后,该应用程序通过练习评估姿势的矢量几何,以提供有用的反馈。姿态估计是一种利用人体图像或视频计算人体关键关节空间位置的方法。这种计算机视觉技术检测图像或视频中的人体姿势,并在输出图像中显示肘部或膝盖等关键点。

A data logger is an electronic device that senses temperature, relative humidity, and other characteristics such as voltage and pulse by combining analog and digital measurements with programming methods. Thus, data acquisition systems (DAQSs) are frequently used in PV facilities to capture all system data to analyze and optimize plant performance. The major purpose of the project is to create a low-cost DAQS. The suggested monitoring system has been used to continuously gather and display the electrical output characteristics of a stand-alone PV system. PV produced voltage, current, and power are examples of such parameters. Furthermore, because the PV module short circuit current is directly proportional to the molar concentration, the global solar radiation may be determined by monitoring it. The proposed system is considered a good solution for collecting the system database to be ready for the analysis and optimization of the PV plant’s performance. The configurations of software and hardware of the proposed system are presented, and the proposed system's performance is tested when integrated with a small size PV system.
数据记录仪是一种电子设备,通过将模拟和数字测量与编程方法相结合来感知温度,相对湿度和其他特性,如电压和脉冲。因此,数据采集系统(DAQSs)经常用于光伏设施,以捕获所有系统数据,以分析和优化工厂性能。该项目的主要目的是创建一个低成本的DAQS。所建议的监测系统已被用于连续收集和显示独立光伏系统的电力输出特性。PV产生的电压、电流和功率就是这些参数的例子。此外,由于PV组件短路电流与摩尔浓度成正比,因此可以通过监测太阳总辐射来确定它。该系统是一个很好的解决方案,可以收集系统数据库,为分析和优化光伏电站的性能做好准备。给出了系统的软、硬件配置,并与小型光伏系统集成测试了系统性能。

A Parallel Environment Designing for OWL Thinking 面向OWL思维的并行环境设计
Pub Date : 1900-01-01 DOI: 10.1051/itmconf/20203203015

A huge volume of information available today is in the form of images and searching the wanted images is very difficult and highly time-consuming. The search may take longer periods as the search volume on the internet is very huge and also the relevance of extracted images is still not up to the mark. The technologies like ontology and languages like OWL help us to tag the images that describe the semantic of the images. Hence, it helps in faster searching of the wanted images. Also, another challenge with OWL and Semantic web is the speed in which one can derive the relationships between various objects extracted from the images. The challenge is to extract the semantic from the images more efficiently using a parallel approach. In this paper, we explore the different techniques for generating semantic knowledge using parallel approaches like the T-box approach, merge classification, extract concept for matching ontology. We propose an enhanced method to speed-up the computation by combining T-box and merge classification techniques.
目前,大量可用的信息以图像的形式存在,搜索所需的图像非常困难且非常耗时。由于互联网上的搜索量非常大,而且提取的图像的相关性还没有达到标准,因此搜索可能需要更长的时间。像本体这样的技术和像OWL这样的语言帮助我们标记图像,描述图像的语义。因此,它有助于更快地搜索所需的图像。此外,OWL和语义网的另一个挑战是从图像中提取各种对象之间的关系的速度。挑战在于使用并行方法更有效地从图像中提取语义。在本文中,我们探索了使用T-box方法、合并分类、提取概念以匹配本体等并行方法生成语义知识的不同技术。我们提出了一种结合t盒和合并分类技术的改进方法来提高计算速度。

Twitter’s primary objective is to facilitate free expression and the exchange of ideas, allowing individuals to share their thoughts, opinions, and information with others without any limitations or constraints. It helps a human being to perceive different scopes and points of view. It is used to serve the public discussion and it should not be used to undermine individuals based on their race, nationality, public standing, rank, sexual orientation, age, disability, or health conditions. So, using hate speech is not appropriate and removal of hate speech is necessary for achieving the goal. This paper aims to utilize machine learning algorithms such as Logistic Regression, Support Vector Machine, Random Forest, CNN-LSTM, and Fuzzy method to compare and evaluate their accuracy in detecting hate speech. The objective is to determine the best model for hate speech detection.

In this paper, a novel method for EEG(Electroencephalography) based emotion recognition is introduced. This method uses transfer learning to extract features from multichannel EEG signals, these features are then arranged in an 8×9 map to represent their spatial location on scalp and then we introduce a CNN model which takes in the spatial feature map and extracts spatial relations between EEG channel and finally classify the emotions. First, EEG signals are converted to spectrogram and passed through a pre-trained image classification model to get a feature vector from spectrogram of EEG. Then, feature vectors of different channels are rearranged and are presented as input to a CNN model which extracts spatial features or dependencies of channels as part of training. Finally, CNN outputs are flattened and passed through dense layer to classify between emotion classes. In this study, SEED, SEED-IV and SEED-V EEG emotion data-sets are used for classification and our method achieves best classification accuracy of 97.09% on SEED, 89.81% on SEED-IV and 88.23% on SEED-V data-set with fivefold cross validation.
本文提出了一种基于脑电图的情绪识别新方法。该方法利用迁移学习从多通道脑电信号中提取特征,然后将这些特征排列成8×9图来表示它们在头皮上的空间位置,然后引入CNN模型,该模型吸收空间特征图,提取脑电信号通道之间的空间关系,最后对情绪进行分类。首先,将脑电信号转换为频谱图,并通过预训练的图像分类模型从脑电信号的频谱图中得到特征向量。然后,将不同通道的特征向量重新排列并作为CNN模型的输入,该模型提取通道的空间特征或依赖关系作为训练的一部分。最后,对CNN输出进行平面化处理,并通过密集层进行情感分类。本研究使用SEED、SEED- iv和SEED- v EEG情绪数据集进行分类,经五重交叉验证,我们的方法在SEED、SEED- iv和SEED- v数据集上的分类准确率分别为97.09%、89.81%和88.23%。

Parkinson’s disease is a chronic neurodegenerative condition that demonstrate the progressive loss of the ability to correlate movements mainly occurs in the elderly. For the purpose of monitoring tremors in Parkinson’s disease, a system has to be designed and developed. For coordination of movements, people with Parkinson’s, deprive of a chemical called dopamine which behaves as the messenger between the brain parts and the nervous system .Detecting Parkinson’s disease is a very arduous task as there is no evidence currently present to do this. Therefore, the main intention of our work is the designing of a system for recognizing Parkinson’s disease at an initial stage. An Android application is being designed that allows the status of PD patients to be assessed based on the tests found on the Unified Parkinson’s Disease Rating Scale approved by the Movement Disorders Society (MDS-UPDRS).
帕金森病是一种慢性神经退行性疾病,表现为运动相关能力的逐渐丧失,主要发生在老年人身上。为了监测帕金森病的震颤,必须设计和开发一个系统。为了协调运动,帕金森氏症患者失去了一种叫做多巴胺的化学物质,多巴胺是大脑部分和神经系统之间的信使。检测帕金森氏症是一项非常艰巨的任务,因为目前还没有证据证明这一点。因此,我们工作的主要目的是设计一个识别帕金森病在初始阶段的系统。目前正在设计一款Android应用程序,该应用程序可以根据运动障碍协会(MDS-UPDRS)批准的统一帕金森病评定量表(Unified Parkinson’s Disease Rating Scale)中的测试来评估PD患者的状态。
