Elements of the methodology of teaching vector graphics based on the free graphic editor LibreOffice Draw at the level of basic general education

The article presents the methodology for teaching the theme "Creation and editing of vector graphic information" in basic school, which can be implemented both in full-time education and using distance learning technologies. The methodology is based on the use of the free vector graphic editor LibreOffice Draw and has been tested over several years in teaching vector computer graphics in the seventh grade in informatics course in full-time, as well as in a distance learning format in 2020. The authors substantiate the need to develop universal methods of teaching information technologies that are insensitive to the form of education (full-time or using distance educational technologies) based on the use of free software. Some principles of constructing a methodology for teaching vector graphics based on the new Federal State Educational Standard of Basic General Education are formulated. As the basic operating system used by the teacher, the domestic free operating system "Alt Education 9" is proposed. The article substantiates the choice of the graphic editor LibreOffice Draw as the optimal software tool to support teaching vector graphics in elementary school, formulates the criteria for choosing LibreOffice Draw as a basic tool for studying computer graphics in grades 6–9 for the implementation of distance learning. A universal scheme for the implementation of a distance lesson in teaching information technology based on the use of free cross-platform software, in particular, teaching vector graphics, is proposed.

Identification of students’ difficulties in understanding of vector concepts using test of understanding of vector

This study is aimed to identify students’ difficulties in understanding vector concepts in physics because many students think that vector concept is very difficult to understand. This research used an embedded approach research design with quantitative descriptive methods and the sampling used a random sampling technique. Total sample of 142 students from two different schools in Central Lombok district. Test of understanding of vector (TUV) used to test the understanding of students consist of 20 item questions, then followed by interview session with several students. Kruskal-Wallis non-parametric descriptive and inferential statistic was used to performed data analysis. The results of this study indicate that (i) students’ ability to understand vector concepts is still lacking and tends to be very lacking; (ii) the most difficult items for students are the unit vector graphic representation and the graphical representation of vector multiplication. The concept of vector is still considered very difficult for students, especially if the item questions use graphical representations. For further researchers, it is better to conduct a study related to what kind of learning system can support and reduce the difficulties faced by students in learning vector concepts especially on graphical representation.

Intelligent support of logistics missions in medical institutions by mobile service robots AMUR-307

Technologies of missions’ generation for the mobile robots (MR) Amur-307 by the parallelized automatic scheduler and their implementation by the integration software (SW) with the hardware block (HB) on 6 power channels (6x30A), with the branched sensorics are considered. The program generator is forming the tasks in the PDDL language based on the route map in vector graphic format, parameters of objects moved by robots, and equipment installed on robots. The developed plan is implemented by the HB and the navigation control program, based on topological information extracted from the map, based on passive oriented visual markers installed in the walls. The robot can work both in real and in virtual environments, using the Webots emulator and/or relying on its own original developments.

Two-Dimensional Analysis of Digital Images through Vector Graphic Editors in Dentistry: New Calibration and Analysis Protocol Based on a Scoping Review

This review was carried out to analyse the functions of three Vector Graphic Editor applications (VGEs) applicable to clinical or research practice, and through this we propose a two-dimensional image analysis protocol in a VGE. We adapted the review method from the PRISMA-ScR protocol. Pubmed, Embase, Web of Science, and Scopus were searched until June 2020 with the following keywords: Vector Graphics Editor, Vector Graphics Editor Dentistry, Adobe Illustrator, Adobe Illustrator Dentistry, Coreldraw, Coreldraw Dentistry, Inkscape, Inkscape Dentistry. The publications found described the functions of the following VGEs: Adobe Illustrator, CorelDRAW, and Inkscape. The possibility of replicating the procedures to perform the VGE functions was analysed using each study’s data. The search yielded 1032 publications. After the selection, 21 articles met the eligibility criteria. They described eight VGE functions: line tracing, landmarks tracing, linear measurement recording, angular measurement recording, image calibration, image overlay, file transfer, and vector graphics development. The features offered by the VGEs bring great precision and objectivity to two-dimensional image analysis. The image analysis and editing procedures are currently not protocolised. Thus, a protocol for image calibration and measurement recording is proposed in order to guarantee the protocol’s replication.

pyGenomeTracks: reproducible plots for multivariate genomic data sets

Motivation Generating publication ready plots to display multiple genomic tracks can pose a serious challenge. Making desirable and accurate figures requires considerable effort. This is usually done by hand or by using a vector graphic software. Results pyGenomeTracks (PGT) is a modular plotting tool that easily combines multiple tracks. It enables a reproducible and standardized generation of highly customizable and publication ready images. Availability PGT is available through a graphical interface on https://usegalaxy.eu and through the command line. It is provided on conda via the bioconda channel, on pip and it is openly developed on github: https://github.com/deeptools/pyGenomeTracks. Supplementary information Supplementary data are available at Bioinformatics online.

What is a diagram, really?

Models for XML documents often focus on text documents, but XML is used for many other kinds of data as well: databases, math, music, vector graphic images, and more. This paper examines how basic document models in the “text” world, do and do not fit a quite different kind of data: vector graphic images, and in particular their very common application for many kinds of diagrams.

GlycoGlyph: a glycan visualizing, drawing and naming application

Motivation Glycan structures are commonly represented using symbols or linear nomenclature such as that from the Consortium for Functional Glycomics (also known as modified IUPAC-condensed nomenclature). No current tool allows for writing the name in such format using a graphical user interface (GUI); thus, names are prone to errors or non-standardized representations. Results Here we present GlycoGlyph, a web application built using JavaScript, which is capable of drawing glycan structures using a GUI and providing the linear nomenclature as an output or using it as an input in a dynamic manner. GlycoGlyph also allows users to save the structures as an SVG vector graphic, and allows users to export the structure as condensed GlycoCT. Availability and implementation The application can be used at: https://glycotoolkit.com/Tools/GlycoGlyph/. The application is tested to work in modern web browsers such as Firefox or Chrome.

Colour Preference Depends on Colour Temperature, Illuminance Level and Object Saturation - a New Metric

A new metric (Rp,2019) is defined as a light source to predict the subjective colour preference impression of an interior scene containing coloured objects illuminated by this light source. The metric is based on the CIE2017 Colour Fidelity Index and the TM-30-15 Colour Vector Graphic. In addition to its dependence on object saturation level, the metric also includes the dependence on correlated colour temperature and on the characteristic illuminance level at the plane on which the coloured objects are arranged. The scale of the metric is labeled with criterion values corresponding to “good” or “very good” colour preference. The aim is to help lighting designers and engineers to determine the illuminance level, colour temperature and object saturation necessary to achieve “good” or “very good” colour preference.

SparK: A Publication-quality NGS Visualization Tool

While there are sophisticated resources available for displaying NGS data, including the Integrative Genomics Viewer (IGV) and the UCSC genome browser, exporting regions and assembling figures for publication remains challenging. In particular, customizing track appearance and overlaying track replicates is a manual and time-consuming process. Here, we present SparK, a tool which auto-generates publication-ready, high-resolution, true vector graphic figures from any NGS-based tracks, including RNA-seq, ChIP-seq, and ATAC-seq. Novel functions of SparK include averaging of replicates, plotting standard deviation tracks, and highlighting significantly changed areas. SparK is written in Python 3, making it executable on any major OS platform. Using command line prompts to generate figures allows later changes to be made very easy. For instance, if the genomic region of the plot needs to be changed, or tracks need to be added or removed, the figure can easily be re-generated within seconds without the manual process of re-exporting and re-assembling everything. After plotting with SparK, changes to the output SVG vector graphic files are simple to make, including text, lines, and colors. SparK is publicly available on GitHub: https://github.com/harbourlab/SparK.
