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.

Now development of the administrative principles is directed on selection of the corresponding forms of total activity of employees of the investment and construction sphere. The methodology of a point of profitability shows, how many production the organization has to realize to refund the expenses. We offer model of management of integration in construction, using the mathematico-statistical analysis and considering calculation of a point of profitability. Here factors – receptor, administrative and effector take place. In experience information of the construction enterprises of Rostov-on-Don was used. The profit after introduction of innovations grows quicker, than before their introduction since the point of profitability decreases after calculation of the organization for invested in innovations. On examples the criterion of expediency of merge of the construction organizations – the carried-out amount of works is shown. On the basis of this criterion it is possible to solve a problem of streamlining of operations in construction systems by integration of information space of organizational and technological, economic and other applied systems.

The main maintenance of a  results of calculation of a thermointense condition of beams depending on various ways of an attachment to the basis - jammed in the basis, with absolutely hard sealing-off on end faces and absence of any communications at end faces is considered. The analysis shows, that the more age of "blocks-communications", the more they possess rigidity. It means, that they are less pliable, and sizes of pressure in the settlement block are close to pressure in the block with the jammed end faces.

In the article a double-gap cavity with anti-phase excitation that has wide application in designs of floating-drift klystrons is considered. One of the ways of reduction of time during machine design of klystron’s cavity is using of the simple analytical expression, allowing to determine the main klystron electrodynamic parameters with a sufficient accuracy for practice. In the article we presented the results of physical and mathematical modeling of the double-gap cavity, the corrected mathematical models were introduced that can be utilized in programs of a prompt optimization of klystron's type devices. The technique of creation of approximate mathematical model in this case was reduced to definition of basic analytical function, and the subsequent approximation between experimental and calculated data by means of a method of planned experiment. In presented work the analysis of adequacy was carry out. Analysis revealed inaccuracy of a resonance frequency of an anti-phase type in chosen ranges of change of influencing factors doesn’t exceed 1%, characteristic impedance- 5%. The received analytical ratios allow carrying out quickly calculation of parameters of the cavity, without labor-consuming and expensive experiments and calculations.

In this work we have investigated the structure of individual single-walled and multi-walled carbon nanotubes by high-resolution electron microscopy and electron diffraction. To grow carbon nanotubes we used a catalytic chemical vapor deposition method. It was shown, that this synthesis protocol gave in general single-walled and double-walled carbon nanotubes with a high level of crystallinity. The diameters of the nanotubes were in the range 1.5 - 7 nm. We also observed that there was a certain level of amorphous carbon deposited on the nanotube surface during the growth. In this work we also present the structure analysis of the double-walled carbon nanotube by means of electron diffraction. We show that the structural date derived from electron microscopy and electron diffraction agree within the experimental error.
