On some properties of homogeneous questionnaires

The properties of the irredundant realized questionnaires with the identical bases of all questions (homogeneous questionnaires) of special types (with equal/unequal questions and equilibrium/nonequilibrium events) are considered. Some properties of homogeneous questionnaires are established, the simple algorithms of their optimization being a generalization of the algorithm of David A. Huffman and simplification of algorithm of P.P. Parkhomenko also are given.

Increasing of safety of navigation on sailing pleasure vessels by means of software and hardware

The actual theme of safety of navigation on sailing vessels is described. Theoretical and practical training is necessary to sail, but it is not always possible to receive training. A software and hardware set allowing to navigate safely was developed to help the crew of a sailing vessel.

Robust non-linear amplitude suppressors of not Gaussian interference

Methods for synthesis and analysis of efficiency of the robust nonlinear suppressors of strong not Gaussian interference on various classes of distribution laws are given. It is shown that all examined classes of distributions and their corresponding characteristics of blocks of nonlinear suppression are non-linear (with the exception of the class of Gaussian distributions P1).

On the influence of the artificial turbulization of the boundary layer on the hydraulic resistance of the round pipe bundle washed by the crossflow of viscous medium

The method of the artificial turbulization of the boundary layer is considered. It leads to a reduction of hydraulic resistance of the round pipe bundle washed by the crossflow of a viscous medium. At the same time the critical Reynolds number ensuring the transition from laminar boundary layer to turbulent decreases.

Research of traction properties of a monoaxial bogie

The description of the research methodology of traction properties of a promising motor car of an electric train on four monoaxial bogies is adduced. Graphs of the displacements of points of the body over axle boxes of the first wheel set and change of utilization coefficient of adhesion weight in transitional modes of movement are shown. Results of the analysis of the obtained dependencies are given.
