The model of the ideal video camera is described, the form of the intrinsic and extrinsic camera parameters is showed. The relations between coordinates of a point in the world coordinate system with coordinates of this point on the image plane are given. The problem of finding extrinsic camera parameters from corresponded world and image points is posed. The error of found extrinsic parameters is estimated by simulation for several configurations of calibration objects consisting of a variable number of points on different distances from the camera and with different angles between them. On the basis of simulation results recommendations are given for the choice of the calibration object in order to improve the accuracy of the extrinsic camera parameters. The best results may be obtained with a configuration consisting of points that have a large angular distance between them and are posed on different distance from camera.

The simulation of two-dimensional spherical crystals consisting of a large number of particles is carried out. These shells were analyzed based on their geometric structure and energy distribution. Various types of defects formed in a state of equilibrium  is considered. Being shown the ambiguity of the existing method of their interpretation. A new way of describing such defects in the close-packed two-dimensional crystals with different topology is suggested.

The kinetics of the electrodeposition of zinc to the steel base of the sulfate electrolyte supplements with synthetic surfactants was studied. Found that at potentials more positive than the equilibrium value the process of pre phase zinc deposition. Additives synthesized organic compounds adsorbed to the surface of the electrode at its cathodic polarization, increasing of overvoltage process. The adsorption is in the range of 0,5•10-7 to 2,6•10-5 mol/сm2.

The paper studies the possibility of quantitative processing of the GPR data for determining the dielectric permittivity and conductivity of a medium (soil samples). Experimental studies are made using radargrams of soil samples with specified values of moisture and conductivity. New methods of quantitative processing of radargrams are proposed in this work to determine the dielectric permittivity and conductivity of soils. The methods were successfully tested on various sections of Russian railways net.
