Currently, the world is actively undergoing digital transformation, which is associated with the introduction of digital technologies in various fields. Methods for predicting and combating various types of diseases are being developed more and more actively. A separate place in this issue is given to pharmacology and reducing the risks of poly-pharmacotherapy. Works in this area have become more and more active in the last three years, and relate primarily to the problems of experimental medicine - the search for new drugs or classification of patients by images. In this connection, the development of algorithms for processing big data in the field of clinical pharmacology, including regulatory documents, instructions for the use of drugs, reliable medical resources for machine learning and building a knowledge base focused on practical application in real medical practice, is becoming increasingly important. One of the considered approaches for solving the problems described above is the search for an effective vector representation of the found concepts (word embedding) to build models of recommendations for the practical use of drugs based on the diagnosis and models for identifying their compatibility. The article presents a software tool for visualizing a graph model of medicines and their classes, considering their incompatibility. The problem of incompatibility of medicines is being investigated. The considered database of medicines, obtained from various sources, and the advantages of its use are described. The article presents the results of the developed prototype of a software tool that allows you to visualize a complete graph of relationships between drugs, a graph of incompatible drugs for a selected drug, and a graph of compatibility of two drugs. Graph model visualization provides a visual representation of complex relationships and allows researchers and pharmacologists to better understand interactions between drugs. The software offer the necessary tools to make informed decisions when prescribing medications and improve safety when using medicines.
当前,世界正在积极经历数字化转型,这与在各个领域引入数字技术有关。预测和防治各类疾病的方法正在得到越来越积极的开发。在这一问题上,药理学和降低多种药物疗法的风险占有单独的一席之地。近三年来,这方面的工作越来越活跃,主要涉及实验医学问题--寻找新药或通过图像对病人进行分类。在这方面,开发用于处理临床药理学领域大数据的算法正变得越来越重要,这些数据包括监管文件、药物使用说明、用于机器学习的可靠医疗资源,以及建立以实际医疗实践中的实际应用为重点的知识库。为解决上述问题而考虑的方法之一是寻找一种有效的矢量表示法来表示所发现的概念(词嵌入),以建立基于诊断的实际用药建议模型和识别药物兼容性的模型。文章介绍了一种软件工具,用于可视化药物及其类别的图模型,同时考虑到它们的不兼容性。目前正在研究药物的不兼容性问题。文章介绍了从各种渠道获得的药物数据库及其使用优势。文章介绍了所开发的软件工具原型的成果,该工具可以将药物之间的完整关系图、所选药物的不相容药物图以及两种药物的相容性图可视化。图形模型可视化提供了复杂关系的可视化表示,使研究人员和药理学家能够更好地理解药物之间的相互作用。该软件提供了必要的工具,使人们在开处方时能做出明智的决定,并提高用药的安全性。

In the present study, non-contact techniques for estimating the deformation of a sheet specimen of aluminium alloy AA5051 (AMg2) subjected to Erichsen cupping test are considered. It is shown that it is possible to get reliable information by numerical simulation, however, for the case when the coefficients of the yield and fracture equations of the material are well-known and validated. This requires the application of confirmatory techniques based on the results of real experiments, for example, through optical 3D-scanning. The realization of the techniques requires preparing the blank prior the experimental stage. The combined technique of speckle interferometry and digital image correlation allows estimating deformations on the outer linear surfaces, but does not indicate deformations of products with curved surfaces and inside the specimen, which requires performing an additional numerical simulation.
在本研究中,采用非接触技术估计了受Erichsen拔罐试验的铝合金AA5051 (AMg2)薄片试样的变形。结果表明,当材料的屈服方程和断裂方程的系数已知并得到验证时,通过数值模拟可以获得可靠的信息。这需要应用基于真实实验结果的验证技术,例如,通过光学3d扫描。该技术的实现需要在实验阶段之前制备毛坯。散斑干涉测量和数字图像相关的组合技术允许估计外线性表面的变形,但不能指示具有曲面和样品内部的产品变形,这需要执行额外的数值模拟。

This article discusses the importance of developing software and hardware complexes for data visualization and improving methods of presenting them in the modeling of low-temperature gas discharge plasma phenomena and related physical processes. In particular, issues related to creating a specialized distributed environment for solving gas discharge modeling tasks are considered. The use of computer graphics for visualization has allowed for a visual analysis of the obtained data and making necessary adjustments to the modeling process interactively with the data. The paper presents the results of visualizing a model of mercury-argon plasma in a coaxial microwave discharge. The application of local cross-sections of the computational domain for visualization has revealed the internal structure and peculiarities of the distribution of the electric field and electron concentration in the discharge tube. The obtained data served as the basis for creating an experimental prototype of a coaxial gas discharge optical radiation source.

The approximation of the tensor appearing at a discretization of the multidimensional function is considered from the viewpoint of storing and treating of the results of parametric computations obtained in computational aerogasdynamics. The new algorithm for the computation of the canonical decomposition using gradient descent and approximately decomposable goal functional is described. This algorithm applies the random set of points on the hyperplane orthogonal to the computed core of the canonical decomposition (“umbrella”) that ensures its flexible application for an approximation of the tensors with a priori unknown rank and may be naturally transferred on such tensor decomposition as the tensor train. The results of the numerical tests are presented for the model six-dimensional functions and for an ensemble of the numerical solutions for the two-dimensional Euler equations. These equations describe the flow of the compressible gas with two crossing shock waves. The Mach number and angles of the flow deflection serve as the flow parameters. The results are provided for the dimensionality 3 (simple numerical solution) and 4 (the ensemble of the numerical solutions in dependence on the Mach number).
从计算空气动力学中参数计算结果的存储和处理的角度考虑了多维函数离散化时张量的逼近。提出了一种新的基于梯度下降和近似可分解目标泛函的正则分解计算算法。该算法在与正则分解(“伞”)的计算核心正交的超平面上应用随机点集,以确保其灵活地应用于具有先验未知秩的张量的近似,并且可以自然地转移到诸如张量序列这样的张量分解上。给出了模型六维函数和二维欧拉方程数值解的集合的数值试验结果。这些方程描述了具有两个交叉激波的可压缩气体的流动。以马赫数和气流偏转角作为流动参数。给出了维数3(简单数值解)和维数4(依赖马赫数的数值解的集合)的结果。

The paper is devoted to the issue of visualization of the algorithm for scheduling parallel tasks. Task scheduling is a key part of the online visualization and parallel programming environment developed by the author. When programming a parallel version of one mathematical application, a suspicion arose that the scheduling algorithm does not optimally distribute the load between the workers. In this connection, it was decided to visualize its work in order to see the overall picture and possible problem areas of the algorithm. The constructed view successfully coped with the problem, and the scheduling algorithm was improved.

The work is devoted to the application of previously developed algorithms and methods of stereo animations construction in the field of biological research on the example of stereo images for functional tomogram of the brain. The construction of stereo images on the autostereoscopic monitor provides an opportunity to obtain an in-depth understanding of the studied object. The autostereoscopic monitor allows viewing stereo images without glasses, while providing a quality not inferior to that of a classical 3D projection stereo system. This work continues the cycle of research conducted at the Keldysh Institute of Applied Mathematics. The specificity of the displayed data allowed to improve authoring libraries for creating stereo images. The research is aimed at developing technologies for constructing stereo images and animations for presenting the results of scientific calculations on classical stereo devices and autostereoscopic monitors. Constructing a stereoscopic visual representation of the results of biological research will enable researchers in the field to gain a deeper understanding of the object under study and its properties.

The need for effective postprocessor analysis of the results of extensive calculations on supercomputers remains extremely high when using new complex computing systems in modeling super- and hypersonic gas flows, predictive modeling of heat and mass transfer processes in jet engines and new energy devices, in solving multiscale problems for astrophysical simulation. Requirements for improving the quality and versatility of new software and visualization codes are increasing with the transition to exascale computing, which requires the improvement of new service systems, in particular systems for visualizing and analyzing the results of multi-scale calculations with dramatically increased input and output data. This paper considers the experience of using an authorized visualization system in the practice of solving some tasks with vortex flow structures and unpredictable instability.

A quantitative study has been made of the flow with shock waves generated in air by a sliding surface discharge lasting less than one microsecond. The high-speed flow was visualized using the shadowgraph method, the process was recorded at a rate of 124 000 frames/s, the exposure time was 1 μs. The aim of this work is to study the dynamics of the two discontinuities: the cylindrical shock wave and the contact surface generated by the discharge. Each experiment allowed several hundred images to be taken of a short-lived gas-dynamic process lasting up to 1 ms. A YOLOv8 convolutional neural network was trained and used to determine the positions of the discontinuities. A data set of 984 markups was labeled. The model on the mAP50 metric achieved 0.887 and the mAP50-95 was 0.557. The model was used to automatically measure the vertical dimensions of the contact discontinuity. It expands at times up to 0.4 - 0.8 ms to a vertical size of 5 - 11 mm. The x-t plots and the velocities of the cylindrical shock waves were measured. It is shown that up to 1 ms after the discharge, the flow development is due to the blast wind motion behind the shock wave. It is shown that the use of computer vision can significantly speed up the analysis of high-speed flow visualizations and the extraction of quantitative information.
本文对持续时间小于1微秒的滑动面放电在空气中产生激波的流动进行了定量研究。采用阴影法对高速流动进行可视化,记录速度为124000帧/s,曝光时间为1 μs。本文的目的是研究两个不连续面:圆柱形激波和放电产生的接触面的动力学。每个实验都允许拍摄数百张持续时间长达1毫秒的短暂气体动力学过程的图像。训练了一个YOLOv8卷积神经网络,并使用它来确定不连续点的位置。标记了984个标记的数据集。mAP50指标上的模型达到0.887,mAP50-95为0.557。该模型用于自动测量接触不连续面的垂直尺寸。它有时膨胀到0.4 - 0.8毫秒,垂直尺寸为5 - 11毫米。测量了圆柱形激波的x-t图和速度。结果表明,在放电后1ms内,气流的发展是由冲击波后的冲击波运动引起的。结果表明,利用计算机视觉可以显著加快高速流的可视化分析和定量信息的提取。

The model on the mAP50 metric achieved 0.887 and the mAP50-95 was 0.557. The model was used to automatically measure the vertical dimensions of the contact discontinuity. It expands at times up to 0.4 - 0.8 ms to a vertical size of 5 - 11 mm. The x-t plots and the velocities of the cylindrical shock waves were measured. It is shown that up to 1 ms after the discharge, the flow development is due to the blast wind motion behind the shock wave. It is shown that the use of computer vision can significantly speed up the analysis of high-speed flow visualizations and the extraction of quantitative information.","PeriodicalId":38328,"journal":{"name":"Scientific Visualization","volume":"17 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135764705","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}

The goal of this research is to explore the scientific literature on virtual environments by conducting a bibliometric analysis. This provides insight into the main topics, most contributing sources, most-cited articles, prolific authors, and countries that are involved in the research. Additionally, this analysis acts as a tool for understanding the intellectual foundation of the structure, worldwide research concentration on this domain, and social structure of the literature on the subject, as well as the knowledge base associated with the use and integration of virtual environments. The research was conducted by analyzing articles indexed in the Scopus database, which is believed to be the top-most database in scope regarding social sciences research. Using the PRISMA sampling technique and VOSviewer software, the data was analyzed to provide an overview of the virtual environment domain, and we reported tables, graphs, and maps to highlight the main performance indicators for the production of articles and their citation. The results show that terms such as "innovation management," "social media analysis," "business development," "digital technology," "customer engagement," "firm performance," "technology management," "virtual environment," "digital capability," and "market performance" have been used regularly. In addition, the density map reveals some of the newer topics of research, such as "industry 4.0," "sustainable development," "digital business strategies," "virtual environment," "artificial intelligence," and "big data technology." This study's results offer a deeper understanding of how the past, present, and future are connected and shed light on any topics that remain unexplored.
本研究的目的是通过文献计量分析来探索虚拟环境的科学文献。这提供了对主要主题、贡献最大的来源、被引用最多的文章、多产的作者和参与研究的国家的深入了解。此外,该分析还可以作为一种工具,用于理解该结构的知识基础、该领域的全球研究集中度、该主题文献的社会结构,以及与虚拟环境的使用和集成相关的知识库。该研究是通过分析被认为是社会科学研究领域最大的数据库Scopus数据库中收录的文章进行的。使用PRISMA采样技术和VOSviewer软件,对数据进行了分析,以提供虚拟环境领域的概述,我们报告了表格、图表和地图,以突出文章生产及其引用的主要性能指标。结果显示,“创新管理”、“社交媒体分析”、“业务发展”、“数字技术”、“客户参与”、“企业绩效”、“技术管理”、“虚拟环境”、“数字能力”和“市场绩效”等术语被经常使用。此外,密度图还揭示了一些较新的研究主题,如“工业4.0”、“可持续发展”、“数字商业战略”、“虚拟环境”、“人工智能”和“大数据技术”。这项研究的结果让我们对过去、现在和未来是如何联系在一起的有了更深入的了解,并揭示了任何尚未探索的话题。
