Realistic Images

The physics laboratory-works creating and operating computer simulations experience is described. A significant amount of laboratory works can be classified as a “black box”. The studied physical phenomenon is hidden from direct observation, the control is carried out by means of electrical measuring devices. It is difficult to distinguish physical reality from its imitation when performing such work, so the virtualization of this one does not require realistic images. The schematic representation of the laboratory installation greatly simplifies the process of creating a simulator. A unique set of installation parameters is formed for each student performing laboratory work on the simulator, which contributes to the independence of the student's work. These parameters are stored in Google Sheets. Their transfer to the laboratory work’s html-template is carried out in encrypted form through the Google Apps Script service. Virtual laboratory work is implemented as a cross-platform web application.

Many problems in metal physics can be adequately described by planar arrays of dislocations, and in analysing them there are two extreme types of approach: either all the dislocations can be regarded as discrete entities, when a numerical procedure must in general be adopted, or they may be smeared into a continuous distribution, when a simple analytical solution is usually available. The present paper introduces a procedure whereby the majority of the dislocations in an array are smeared into a continuous distribution, while those that are intimately concerned with the particular physical phenomenon under consideration are allowed to remain discrete. The main advantage of this approach is that it allows for ease of solution, while preserving a high degree of physical reality. Particular types of dislocation array are considered, the accuracy of the method being demonstrated by comparing, where possible, the results with those obtained assuming that all the dislocations are discrete. Both singular integral equation and potential theory techniques are employed, and the results are applied in a brief discussion of the problem of cleavage crack nucleation in crystalline solids.

This paper focuses on Quantum GIS (QGIS), an open-source cross-platform application that allows to visualize geospatial data in various formats. The paper indicated the main advantages of QGIS web application (second version) – QGIS Web Client 2: free distribution; free access to open-source code, which allows to write or modify a script or program module; permission to modify the source code; the ability to install the program on various operating systems (Windows, Mac OS, Ubuntu, etc.); a large library of free modules for working with geodata; the ability to publish maps on the web using Mapserver and other analogs; the ability to download space images from different sources (Yandex, Google, Bing Aerial, etc.); the ability to post data and publish projects on the Internet using the QGIS Cloud plugin. The technical requirements for the design of the QWC2 web application are presented; instructions for installing and QWC2 configuration on the available infrastructure are also given. The testing and the functionality of QWC2 application were presented on practical examples (area / length / coordinate measurements; thumbnail / redline functionality; generation of permalinks; PDF printing; ability to export maps in different images; import WMS/WFS; map comparison).

Natural Way

As the use of computers in our daily lives increases, so has the need for a natural procedure to interact with the computers. The ultimate aim of human computer interaction is to bring the change that there is always a natural way of interacting with computers coupled with ease and flexibility. Printed and textual media such as prescriptions, invoices, receipts, etc. occupies a large segment of our day-to-day activities and given their volume, it is inefficient to manage them physically as there’s always an associated risk of fading, damage, misplacing, etc. and hence a medium is required for their digital conversion. In this project, we have developed a robust, cross-platform web application that can process the images using PyTesseract based algorithms that can efficiently extract the textual data to facilitate the storage and retrieval of the same. The extracted text can be downloaded as a text file and can also be translated into the desired language. This is an active field of research and thus this paper also discusses various current implementations of the mentioned concept. The Optical Character Recognition framework finds applications in a variety of fields such as business process activities, number plate recognition, KYC and banking processes to name a few.

The Creation

The research is aimed at developing and implementing proposals for automating the activities of scientific and educational organizations of the Federal Penitentiary Service of Russia for accounting, collecting, processing and analyzing the information on the results of scientific and scientific&technical activities of scientific and educational organizations of the Federal Penitentiary Service of Russia.The practical and scientific significance of the work lies in the development and testing of algorithms, the study of information flows and structures at the creation of an information system for recording the results of scientific activities of scientific and educational organizations of the Federal Penitentiary Service of Russia – the information system «UIS Nauka» (UIS Science). The research methodology is based on the use of methods of systems analysis, modeling of information flows, the theory of complex systems. The study made it possible to formulate functional requirements for the system for recording the results of scientific activity and implement them in a prototype of the information system «UIS Nauka» in the form of a cross-platform, cross-browser web application. The creation of this system made it possible to provide the Federal Penitentiary Service of Russia with an effective tool for planning, coordinating, and recording the results of scientific activities. Key words: information system «UIS Nauka», scientific research, scientific and technical activities, the penal system of the Russian Federation.
