"This article is devoted to the development of the method for modeling elements of microsystems technology(MST) of membrane type. In this paper perforated membranes are considered and the impact of perforation on the mechanical properties of the membranes is examined. In numerical simulations of the elements it is proposed to use the equivalent mechanical parameters of perforated membranes obtained at the initial stage of the simulation. This will allow to obtain find the optimal parameters of perforation, reduce the time and resource modeling of MST elements. To test the technique numerical experiments were conducted for the two square membranes with sides 1.5 and 3 mm fixed on the contour of the same thickness. We studied the influence of the size of the perforation on the equivalent Young's modulus of the perforated membrane. "

The problem of manufacturing technology heterostructures pezofaza - metal considered in the article. Complexity consists in the fact that during the removal of the polymer in the system at low temperatures are formed porous layers, formed powders separated metal layers, having island macrostructure. One way to solve the problem - reducing the firing temperature heterostructures. Proposed to decrease the sintering temperature by using of functionally active glass-phases. Reducing the sintering temperature of products also allows to replace platinum electrodes inexpensive silver-based alloys. Obtained by solid state reaction method of piezoceramic material has a low sintering temperature (980 ° C) and high electrical parameters. Found that not only the proportion of the vitreous mass, but also their qualitative influence on the properties of piezomaterials

Piezoelectric ceramics on the basis of the phase of (1-x) PbTiO3-xPbZrO3 is the basis of most high-performance piezoelectric materials. Electrophysical and mechanical properties of these materials can vary widely in different ways. Traditional methods include changes in composition within the morphotropic region and doping. Now is the study of the influence of topical makrolegirovaniya the material properties of the PZT system. As a model system was selected phase of the PZT system, the compositions of which MO belong, one of which contains a dopant in the sublattice (A) and another - in the sublattice dopants (B). The studies established that one of the effective ways of varying the parameters piezomaterials may be the formation of solid solutions on the basis of two or more piezoelectric phases having different combinations of electrical parameters

Due to the depletion of the natural base of non-metallic minerals used for the production of high quality aggregates for concrete, and also because of the significant damage to the environment when working sartirovochnyh crushing plants becomes relevant greater use of fine-grained concrete on local , not always of high-quality materials. Rostov region has large reserves of river small and very fine sand , not suitable for the preparation of concrete mixes. The article suggests ways to improve the quality of fine concrete local fine sands with the introduction of their composition from fine mineral filler (the TMN ), the role of which carry waste production and processing opal - carbonate- kristabolitovyh kremnizemistyh flasks Maslovskoye deposit Rostov region. Chosen route of administration mikronaponitelya and optimal dosage , to analyze the impact of THM on Water-solid, water-cement ratio and the strength of concrete .

The technique of the geometrical analysis and the analysis of force loading of combined drills with the replaceable multiface plates is offered in this work. This technique is allowing to determine geometrical parameters and specific force loadings in each point of a plate’s cutting edge taking into account its orientation in the drill case. Application of this technique allowed to establish the reasons of the drill’s low durability. The offered technique allows to design drills from the minimum unbalanced radial component of cutting force which increases its working capacity and the processed holes quality. New designs of combined drills both with two, and with three replaceable multiface plates are offered in this work. The durability of this new drills is increased by the plates mutual turn for the minimization of an unbalanced radial component of cutting force

Results of researches on joint influence of specific pressure of pressing and firing temperature on physico-mechanical properties of laboratory samples on the basis of atyukhtinsky clay raw materials is shown. For the purpose of increase of frost resistance of the burned samples into structure of masses entered a carbonat containing modifying additive in an amount of 5%. For a quantitative assessment of influence of the specified factors on the main indicators of the burned samples researches with application of mathematical planning of experiment and computer processing of results were conducted. Specific pressure of pressing varied within 20±5 MPa, firing temperature – 1000±50 0C. By results of experiment the regression equations are received. It is defined that at increase of value of both varied factors, frost resistance and durability of samples increase, and water absorption – decreases. It is shown that, operating even with two technology factors – the specific pressure of pressing and firing temperature – it is possible to change significantly properties of finished products, and, using the received equations, it is possible to predict future properties of products at a stage of their production.

The article deals with the analysis of intermittent lanes priority based on simulation. The implementation of intermittent lanes priority system is only possible within the framework of urban intelligent transportation system (ITS).  In some cases, there are not always enough ITS components for the operation of intermittent lanes priority system. Based on the simulation it is possible to determine the efficiency of the intermittent lanes priority system with the minimum or complete number ITS components. To compare the effectiveness of intermittent lanes priority system the simulation was performed for the four scenarios:
1. Without the use of public transport priority
2.  Classically  marked priority lane
3. Using the intermittent lanes priority system with a minimum number of ITS components
4. Using the intermittent lanes priority system with the full amount of ITS components 
According the results of simulation we concluded that the minimal intermittent lanes priority system is noticeably inferior to a fully functional intermittent lanes priority system on the effectiveness, but such system does not require a high level of development of the urban ITS and can be considered as the first stage of a complete intermittent lanes priority system.
