    The introduction of the comprehensive program "Boundary control" is considered on the example of a control and experimental group. The results of the effectiveness of this complex have been proved practically and theoretically: the progress of cadets has increased, and calculations of statistical estimates have shown that the calculated value is less than the critical one. That is, it can be concluded that the differences in the estimates between the experimental and control groups are statistically insignificant at a given significance level. That is, for comparison, approximately equal in knowledge two groups were taken.

  • Synthesis of kinematic surfaces based on elliptic rotation of the plane

    The algorithm of forming of kinematic surfaces with a constant cross-sectional area based on a complex equiaffine transformation of the plane (elliptic rotation) is considered. Functional dependences of elliptic rotation parameters for the formation of a one-parameter family of equiaffine lines on a plane are determined. At the same time the received families of lines can not include the line prototype and the line image at the set constant parameters of rotation. Conditions of receiving the line prototype and the line image at the set parameter of family and the parametrical equations of shift of the geometrical center of a curve are defined. The conditions for the formation of central surfaces are determined. It is established that the surfaces obtained can be periodic. The domains of admissible values of the parameters and functions included in the parametric equations of one-parameter families of curves are determined. It is shown that as a closed loop one can use not only an analytically determined curve, but also a polyline (for example, a polygon). Examples of kinematic surfaces are given.

  • Calibrating the triaxial accelerometer according to a number of measurements with different orientation

    The problem of calibration of a three-axis acceleration sensor is considered. A number of measurements obtained with the sensor at its different orientations in space are used as initial data for calibration. It is assumed that the sensor is stationary for each orientation variant. The measurement data are averaged at each static sensor position, and the averaged results are used as parameters in a system of nonlinear equations that are solved by the Levenberg-Marquardt method. The results of the proposed method in the article are presented in the experiment with a real sensor, which allows to check its effectiveness.

  • On the neutral loading of a disk under thermal and force influences

    A thin circular disk is considered, the material of which exhibits elastic and plastic properties under thermal and force influences. In the central part of the disk, the temperature field is uniform. At the boundary of the disk, pressure and a constant temperature are set. Approximation of a plane stress state is adopted. The additive form of the connection of full, elastic, plastic deformations and deformations under free thermal expansion is considered. Elastic deformations are expressed in terms of stresses according to Hooke's law. A linear approximation of the dependence of the plasticity limit on temperature is proposed. The possibility of neutral loading of the central region of the disk and its external boundary is shown. Especially distinguished is the condition for the plasticity of Tresca.
