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 ...

In the paper, a solution of unsteady heat transfer problem with periodic boundary condition by means of boundary integral equations method was presented. Also was presented the results of numerical simulation of heat transfer in two dimensional area with oscillating temperature on the boundary.

The algorithm of animation of frictional auto-oscillations presented at a translational motion of a support of cutting machines, parameters of auto-oscillations are defined, the alternative of laboratory operation on examination of these oscillations is offered.

The formulae for asymptotic expression of eigenvalues and eigenfunctions of first boundary value problem for cubic anisotropy bodies are obtained.

The main limitation of assembly of the connections formed by mechanic pressing-in are noted, the new engineering solution on hydropress disassembly connections is described, the basic theoretical relations of process of a hydrothrust in a part jointing with guaranteed interference are adduced.

The dynamic analysis of motion of lever mechanism of drive of stand for the test of gusenits of tractors is resulted. Computation is conducted by the Mertsalova N.I. method for the set mode of operations. On results analysis of motion the recommendations are resulted on reduction of the dynamic workload on links and bearing of stand.

The article describes the peculiarities of software and methodological complex "The Dynamic analysis of lever mechanisms", which is used in course designing at the rate "Theory of mechanisms and machines".

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 ...

А mathematical operation model has been found expedient to determine the effectiveness of a tillage unit operation under specified soil conditions as well as operation parameters and modes when this unit is combined with a particular tractor. The model-based PC software supplies the production and specific fuel consumption rates within the whole range of working speeds and soil ...
