Technical state analysis of control objects task is being considered. An approach based on simulation of objects operation with nonstationary random processes in the form of Fourier integral in AnyLogic environment is suggested and stationary of the processes validated. This method dramatically increases the efficiency of decision-making processes while emergency situations preventing.

The paper describes the flight simulator with augmented reality pilot interface (patent protected). The paper describes the flight simulator with pilot’s interface developed in the university educational and training center and the design of experiments proving the effectiveness of such an interface.

The article describes the three years’ experience of Humanities Institute of the Siberian Federal University research team in the field of creating virtual reconstructions of historical and cultural heritage. Methodological approaches to the construction of complex three-dimensional objects on the example of constructing 3d-models of the Troickaya, Uspenskaya, Voskresenskaya, Preobrazhenskaya churches, Bogoyavlensky cathedral, Spassky monastery are presented. Implementation of the author’s approach in terms of three-dimensional modeling allows the use of three-dimensional models in real time based on 3d-engine.

The stage-by-stage modeling of the automobile body by the multiparameter equations with alphabetic parameters for geometrical characteristics and a technique of the surfaces equations of construction with continuous curvature function with the help of R-functions is considered. The work of new high-speed system of the equations of geometrical objects surfaces visualization in 3D is illustrated.

Execution of on-board geographic information applications is based on the use of spatial data. However airborne computer systems have quite limited computational power. To provide for the execution of resourceintensive on-board geographic information applications in an acceptable time, different means of situational adaptation of digital spatial data are used. The method described represents spatial data as a set of step-bystep approximations, which makes it possible to provide their situational adaptation by fetching data at the required level of detail.

The method of image comparison based on the construction of vector spaces of image attributes by Gaussian blurring is proposed. The results obtained show practical applicability of the algorithm, for example in the recognition process using just one sample per person (OSPP) stored in the database.
