The article proposes to develop a method for determining the conformity of vector illustration to the laws of composition and design, which will help to engage in artistic work for people without special skills and abilities. The concept of the centre of the composition is analysed. The main criterion of equilibrium is determined - the distance between the optical and composite centre. As the first stage of the developed method, it is offered to define the area of an element and to bring an arbitrary figure to a polygon. An algorithm for determining the area of an object of arbitrary shape has been developed. The process of colour density determination is analysed, and its algorithm is developed. An algorithm for determining the equilibrium of the composition is proposed. A script has been created that implements the method of determining the compliance of vector illustration with the laws of composition and design. A script based on a specific one has been tested during a number of tests. According to the test results, the conclusions about the correct operation of the script were confirmed. A prototype of an automation system for creating vector illustrations in Adobe Illustrator has been created.
The article describes the technology for automation of work with sources of information on the Internet. The created technology includes a development of a web service for storing and processing data; creation of a client part for viewing, editing and deleting records from the service; development of a browser extension for instant addition of articles to a web service database. Addition of records to the service is implemented by the development of an extension to Google Chrome browser. Creation of an extension involves getting information about the author of the article, the title of the article, addresses, key expressions, and highlighted text. Regular expressions and recursive search are used to obtain information about the author of the text. The article offers algorithms for finding the name of a literary source and its author. In order to allow the web service to interact with other services or programs, a REST service was developed in the article. A graphical user interface to display and edit records was developed for the web service using the AngularJS JavaScript framework. For the client part, a mechanism of an on request citations search and a mechanism of reference list formation for the selected citations is proposed. For the on request citations search, the article suggests the algorithm of citations ranking. Appropriate plugins for Google Chrome have been developed, which allow to connect content levels, background, and pop-up with each other. Functions for authorization, receiving a token, information search launch, search for an author, and a bibliographic record creation have been created.
The article is devoted to the research of variants of drinking water supply of National Guard of Ukraine units which perform their tasks according to their assignment outside the permanent deployment points. The article also deals with theoretical provisions, which can be taken as a basis for the methodology of substantiation of the optimal plan of such supply. It is noted that drinking water is an important resource in the system of food supply of military units, the lack or shortage of which for a relatively short period of time significantly affects the combat capabilities of the units. Based on this, the possibility of diversifying the sources of drinking water supply for the needs of the troops is studied. Both traditional options of drinking water supply for NGU needs and new ones, which are expected to be implemented in practice in the near future, are considered. Expanding the list of possible sources of potable water supply will contribute to increasing the reliability of water supply and reducing the cost of related logistics operations. Taking into account the presented options for providing drinking water, possible points of delivery of bottled drinking water to units that perform their tasks autonomously in difficult conditions were identified. The presence of several points of drinking water supply to units necessitates the development of a water supply plan. One of the key requirements for such a plan is minimization of total costs. It is shown that the transport problem of linear programming can be used as the basis for developing an optimal plan for supplying drinking bottled water to military units. In this case, the target function is reduced to a minimum of total costs of water delivery. The constraints affecting the processes and determining the search area of the optimal solution are formulated, the general approach to solving the formulated optimization problem is characterized.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
