The authors propose a method for determining the total impact energy of a bus rollover to the conditions of the Rules of the United Nations Economic Commission for Europe № 66 (UNECE) intended for the certification of passenger motor vehicles of category M3. Propose an adjustment to the formula for calculating the height of the fall of the center of gravity of the bus.

Keywords: The bus, safety of bus construction, strength, deformation, a centre of mass, energy.

In this paper we consider the problem of constructing a classification algorithm signals using self-organizing hybrid neural networks and fast wavelet transform, which is a special type of linear transformation of the signals and these signals are displayed physical data about the processes and physical properties of natural environments and objects implemented using fast neural networks.

Keywords: signal, classification, neural network, self-organization, the wavelet.

The results of analysis of computational aspects of the method of obtaining the XANES spectra for Ru L2 ,3-edges by integrating the dipole transition matrix elements involving DFT. The convergence of the numerical integration procedure for the parameters used in the earlier papers, crystals as an example [Ru (NH3) 6] 3 +. More specifically, it is proved that it is possible to use a small area of ​​integration and big enough step between points, which helps to minimize the requirements for computing power and offers the prospect of using this method for the simulation of the XANES spectra in coordinated ruthenium catalysts for splitting water research in the field of solar energy.

The article offers a general gradient methods for all-adaptive method. With the help of an experimental environment was developed by a comparative analysis of gradient methods of finding the minimum. As a result of experiments, it was found that the adaptive method for approaching to a minimum minimal number of iterations. Thus encouraged to use this method in the optimization of the error function, artificial neural network training. 
Keywords: neural networks, gradient methods, teaching methods, analysis of optimization techniques.

The construction of a two-dimensional tiling by a specific projection of three-dimensional cubic lattice is considered. Different a periodic tiling’s, consisting of equal rhombi, are obtained by different choice of the projection region. They are ordinary a periodic tiling, having local elements of symmetry group С6v and chiral trigonal stacking, built like chiral pentagonal Penrose’s quasilattice [1], which occurs in virus cap sides.

Keywords: Quasicrystal, quasilattice, two-dimensionalquasicrystal, chiral quasicrystal.

Offers intelligent method of assessing the reliability of data (verification), in databases, based on the theory of artificial neural networks. The method consists of three steps: data clustering using the Kohonen network, training radial basic network and its computation using the validation database table rows. To create a radial basis networks and their training Backpropagation developed software tool. The proposed verification method of data can be used in various applications of information systems.
Keywords: database, relational algebra, verification, radial basis neural network training neural networks, Kohonen networks, clustering.
