Creation on besed Wavelet-transform of information measurement system for voicedata estimation and protection

One of the most informative human speech-creating organ for speech recognition problem is voice source that effects basic tone frequency of speech signal. According to researches, human hearing system uses basic tone frequency for speech recognition with high reliability, but it is sensitive to low-frequency noises – so appeared idea to use spectral characteristics of speech signal segments, where extremums of correlation function can be found, as additional features.

Development of interval methods with the use of conception of vagueness for the increase of exactness of estimation of results of the control measurings of parameters of informing signals

The new going is developed near the evaluation of exactness of results of measurings by the evaluation of their vagueness. This approach differs from the known (existing) evaluations of exactness of measurings, which it was assumed at, that constituents had normal distribution, which does not depend on the type of distributing of constituents, influencing on a result. For this purpose as an initial size the function of belonging, the special case of which is probability, which interval estimations, uniting subjective and experimental information, were got at, was utillized.

Creation of information and measurement system for cours and trim based on surface acoustic accelerometers

Experimtntal studies of information-measuring system showed prospects for use such  devices for  vehicle security system  and the  measurement of  stress-deforming state of railway locomotives. Combining them into a single complex with a satellite navigation systtmand a digital maps aliow to accurately determine the position of the car on the road.
