The correlation analysis of weight values of direction vectors and their order numbers of normalized vector model for objects under investigation is proposed. The experimental results of construction of the regression line are represented, as well as ones for calculation of theoretical-correlation ratio, similarity measure and classification of objects under investigation for a ...

For researching the movement of flywheel vehicles the physical model is proposed. Physical model as well as real car has a flywheel engine which rotates with high speed. In the article the main parameters of such model and flywheel engine are calculated. It is shown that the engine of the model has parameters which can easily be achieved while constructing.

In а difference of usual stability definition methods of a spring physical pendulum, in this article stability of a spring physical pendulum defined using methods created by A.M. Lapunov. In the result, connection between different parameters of spring and pendulum was formalized, and defined a point of stable pendulum position.

The vacuum deposition process and electrophysical parameters of super-thin fdms of rare earth elements (REE) oxides at reactive magnetron dispersion of metallic targets in the mixture of argon and oxygen were investigated. It is established that in the optimum technological regime (voltage discharge 400- 440 V, underlayer temperature 573-598 К) the o.xides of yttrium and holmium ...

In the work, a solution to a problem of oscillatory flow of viscous incompressible liquid in a rectilinear pipe of circular section, completely filled with the liquid was presented. The way of solving flow generated by pressure pulsation and the pipe oscillation to the flow direction was also-discussed. The behaviour of the liquid for the selected spectrum of its frequency and ...

The September 11, 2001 events attracted the attention of civil engineers of the world to the problem of safety of towers and skyscrapers. According to recent studies, the WTC collapse was caused by man-made explosions on a critical floor located much lower than the floors hit by terrorist planes which supports the wide-spread rumor in the U.S. that MASAD agents used the aftermath ...

The equation of characteristics for system of the equations of movement cubic anisotropic environment which thermal properties are described by the hyperbolic law of heat conductivity is obtained.

В докладе описано построение и апробация конечноэлементной модели шины, построенной в программном продукте «MSC.Marc». Моделируется комбинированное (поэтапное) нагружение шины и учитывается анизотропия упругих свойств материала с экспериментальной проверкой параметров при статическом нагружении.

Results of the investigation integral wavelet transforms are given. Acting and boundedness conditions for the integral wavelet transforms with compact support are obtained. Theorems of an inversion of the integral wavelet transform in the space of square-summable functions and the pointwise convergence of the inverse wavelet transform under Dini condition are stated.
