Alexeev A. A., Kulikov A. I., Starushkin V. G. Visual Geological Media Designer "Seismic Model Manager"
There are many problems with the correct and non-contradictory geological cross-section model making. These problems are very actual today in geophysics. Also there are a lot of different algorithms and geophysical formats. Therefore geophysicist-specialists need to have a special product to build geophysical models and to run algorithms.
Our product affords an opportunity to create, modify and save in different formats geophysical models. Seismic Model Editor as a part of Seismic Model Manager is a special vector editor and it allows geophysicist to build any model of geological cross-section. Editor supports model validation according to the rales described in science-based model. An important point is that any model modifying also changes corresponding geophysical data of the current model. So, visual editing of this model changes model parameters too.
Seismic Model Manager Client forms a part of Seismic Model Manager and allows user to upload a created model to a server and to run a task using available algorithm. Then Client should get a task results from a server and send it to client's computer. This solution provides a remote work for geophysicists
Keywords: geological media, data visualization, visual editor, isogeometric smoothing.

Malykhina G. F., Merkusfeva A. V. Using the Neural Network and Wavelet Transformation Jointly for Nonslationary Signal Analysis
We present some applications of joint using the neural network and wavelet-transformation (WT) in the problems of non-stationary signal analysis. The first problem relates to speech signal (SP) monitoring system where WT implementation is used for SP compression, probability distribution identification of signal WT and wavelet-filtration with adapted threshold. Neural network algorithm is used for recognizing the signal frame type (speech/pause) and controlling two phases: thresholds determination (in the pause frames) and wavelet-filtration of speech signal on the basis of these thresholds (in the speech frames). By such a method, the adaptation to noise level variations is achieved. The expansion of a signal is obtained on the basis of wavelet packet, frequency sub-bands of which approximate the critical bands of perceptual model. New relations are obtained for threshold calculation on the basis of exponential-power distribution, which generalize Cramer's expression for maximum value distribution for Gauss's variable. That makes it possible to filter (in the wavelet domain) the noises of most general type. In the second problem, we suppose the algorithm for estimating free-gas levels in commodity-oil pipelines. The method is based on non-contact radiation densitometer-device. Neural network implements identification of informational significance of WT signal frames: time intervals with gas in the oil flow and intervals having no gas content.
