Automated digitization of radial charts
Radial charts were commonly used in the industry to allow retrospective assessment of technological parameters. Today it is relevant to digitize the obtained data in order to simplify the automation of technological processes. Digitization of radial charts by means of standard methods is carried out with the help of human labor at significant time costs. The article proposes an automated method for digitizing radial charts using software, developed in the LabVIEW programming environment. The results of processing radial charts are displayed on the screen in numerical and graphical form, and can also be exported to a file (for example, to Notepad or MS Excel). The presented technique can be applied to images obtained on a color or black-and-white scanner, which minimizes geometric distortions, associated with the conversion of a paper document into electronic form, and ensures recognition quality of the clear plot line with an average relative error of up to 3 %. In case of ink fading or perspective photos of the diagram, the value of relative error can reach 8 %, as a result of which additional manual correction of the data will be required.

Identification of degradation of soil and vegetable communities testing technogenic loading on materials of space shooting
- Authors:
- D. S. Korelskii
The basic principles on the use of satellite images of different resolution to assess the state of natural soil and plant communities with severe human impacts, primarily atmospheric. Researchers give now various signs of change of qualitative and quantitative structure of vegetation under technogenic loading. However all of them have essential shortcomings that demands continuation of researches in the field for the purpose of increase of reliability of allocation of zones of a breaking of plant communities in an operative mode.

Experience of mediatext in social culture teaching creating
- Authors:
- I. V. Trofimova
This article is devoted a problem of creation of the mediatext as new format for presentation of the scientific information. On a material of culture of the 1930 which have marked transition from avant-garde to totalitarianism, the (video) picture reflecting leading tendencies of an epoch and the form of their artistic realisation is built.
