A voice activity detector (VAD) is a device, which analyses a speech signal and generates the signal corresponding to the period containing only noise. In the present work is offered VAD, which increases the probability of correct detection the presence or absence of human speech.
The correct detection begins with SNR 7-10 dB. The quality of derived speech signal remains the same.

To solve the problem of choosing an algorithm of optimal allocation of resources to development of the energy producing industry, initially held the formalization of this task and the required payment ratio. The relationship led to the conclusion of one of the most effective methods for finding optimal solutions-dynamic programming method

The core of any economy is the production, creation of economic output. No production can not be use. That's enterprises produce products that perform work and services, ie provide the basis for consumption and increase national wealth. Matter how well the company what their financial condition, depends on the health of the economy and the industrial might of the state. If present schematically the entire system of economic governance in the country in the form of a pyramid, its base are businesses. State, regional, departmental management can be considered in relation to the processes occurring at the level of the enterprise, just as the add-on, secondary phenomena.

A method of expanding the bandwidth and improve the performance of the differential voltage divider – attenuator (AT), which have parasitic capacitance on the outputs C01, C02. Wide range of transmission of the AT provided by introducing a compensation circuit C01, C02, which is achieving data quality indicators. Simulation results of desired are shown.
Keywords: a resistive voltage divider, differential attenuator, the parasitic сapacitance load, speed, upper frequency limit, analog-to-digital converters.
There is considered the problem of structuring indicators of the quality of information-computing systems, including transport. For each quality indicator is determined by the number of corresponding criteria. An algorithm for analysis of subscriber delays.

This article deals with the unification of the elements of wood as on the principle of similarity with the material counterpart. Also estimated the economic benefits of the technical parameters of Glulam. As a result of optimizing the size of these elements. Unification is held on the main criterion of similarity bearing members with the solution graphically. Resulting in optimal size sections are then calculated the opportunity cost of production.
Keywords: unification, glued wooden structures
In article the direct connection of a condition of soils and quality of a formed superficial diffusion drain is considered. For minimization of pollution of a superficial drain and ground waters when unloading them in a reservoir it is offered to use coal mining waste as a sorbent of organic and inorganic pollution. Thus, the area of utilization of dump breeds of coal mines for nature protection and soil-improving actions extends.
Keywords: Dump breeds of coal mines; sorbent; minimization of pollution of a superficial drain; the urbanized territories; anthropogenous impact on the soil

This article addresses options for building advanced of resistive voltage dividers (attenuator), providing a reduction in a given number of once input voltage in a wide range of operating frequencies. To correct the frequency error in the AT parasitic capacitance the load is proposed modified scheme with the special frequency attenuator correction, which allows for one to two orders extend the range of working frequencies the AT and increase performance.
Results of computer modeling.

The titanium dioxide synthesized by an electrochemical method is a perspective material for use in solar elements and catalysts of cleaning of water and air environments. Regularities of electrochemical synthesis of titanium dioxide in glycerin dilute solutions (1:1) in the presence of ammonium fluoride at 2-14 V are investigated. Mathematical scheduling of synthesis process according to plans of first order with use of the complete three-factorial experiment is carried out, the adequate regression equations for formation processes of a titanium dioxide in the field of potentials 8-14 V are received. The electron microscopy method proved porosity of synthesizable layers of titanium dioxide. Water content influence in electrolyte on the speed of electrochemical process and potential size influence on titanium dioxide materials yield is established. It is shown that under the chosen electrolysis conditions electrochemical process is accompanied by the considerable chemical disolution of a titanium. Electrochemical processes in water containing glycerin are investigated by a cyclic voltammetry method. It is established that at electrochemical oxidation of Ti in water containing glycerin (1:1) porous TiO2 with a materials yield no more than 25% is formed.

Structural changes in cumulative labor displace the purposes of social development and generate understanding of that the economy exists for the person, and people – the main value of modern society. The evolution of the term tracked in article the sociolabor relations, consideration of elements, levels and the purposes of the sociolabor relations, the characteristic of types of regulation of the sociolabor relations and an assessment of system of the sociolabor relations of Russia allowed to add definitions of the sociolabor relations by concept «the human capital» and to define system of the sociolabor relations of market economy as a complex of relationship concerning development and effective use of the human capital.

The article deals with research problems, tendencies and laws of development of the industry of North Ossetia-Alania. The analysis of industrial production of the region, including the volume of shipped goods of own production, executed works and services by own forces by types of activity: production of minerals, manufacturing industries, production and distribution of electricity, gas and water. The analysis in the dynamics of the трехлетиям the period revealed the presence and size of the negative or positive deviation, as well as levels of stability.
