Under a laboratory modeling of two methods of sound velocity profile recovering in water medium in a rectangular distant sounding scheme both methods of SVP recovering showed approximately equal accuracy. The advantage of ray factor method in comparison with linearization method is an absence of necessity of integral ray equation solving and making a spline-interpolation of experimental data. This simplifies the SVP recovering problem and increases it's accuracy.","PeriodicalId":425905,"journal":{"name":"2006 8th International Conference on Actual Problems of Electronic Instrument Engineering","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125778273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The induced voltage at generator yields a DC current caused by load resistor. That current also is the main source for generator excitation holding the generator in stable steady state operation in connection with hysteresis in magnetic circuit. If we apply a small curr it in the auxiliary external excitation of generator we produce either a filed-increusing or a field-decreasing component in magnetic field. A constant small counter-excitation will reduce the field until it gets zero. If this small counter-excitation is present for all the lime we will reverse the field and finally establish a field in counter-direction. At opposite polarity of current and field we reach again a condition stabilized by magnetic saturation at the generator. The established system is small- scale model of earth magnetic field described by geodynamic generator. This implies the existence of enormous currents in the core of the earth which cause the magnetic field in the range of about 1 milliTesla on earth surface. The small external current in the model has its equivalent in the stream of charged particles emitted by the sun. The effect of magnetic field reversal in the 1kW-model can be viewed by several display units over some seconds rather than millions years in reality.","PeriodicalId":425905,"journal":{"name":"2006 8th International Conference on Actual Problems of Electronic Instrument Engineering","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127462066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The drawback of such a technique is a significant loss of the diagnostic information. The method of ocular artifact suppression in EEG, based on wavelet analysis, is investigated in this study. However different groups are proposing various combinations of wavelet mother functions, thresholds and so on, and each group achieves good results by their own method. Here we compare the efficiency of using different wavelet mother functions in the procedure of ocular artifacts suppression. By co-ordination of results in different estimation ways (some of them are cross-correlation, kurtosis and relative entropy by Shannon) we could conclude about efficiency of different wavelet basises and consistent of proposed ways of estimation. Results of investigation can be used as practical recommendations in developing of EEG de-noising algorithms.","PeriodicalId":425905,"journal":{"name":"2006 8th International Conference on Actual Problems of Electronic Instrument Engineering","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125142109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this connexion, the problem of broad band matching arbitrary load immittances to become very important, especially on the ultrahigh frequency. The optimal and theoretically proven decision of this problem is absent, although actuality of it. It is necessary to note, that existent computer-based systems give only particular solution of this problem. Therefore, the computer-based system for synthesis of broadband matching and filtering devices (CBSSBMFD) for arbitrary load immittances was created. CBSSBMFD use Windows OS. CBSSBMFD enable to synthesize broadband matching and filtering devices on lumped elements, on uniform transmission lines, on stepped nonuniform sections of transmission line. The result of synthesis is Z ore Y matrix of passive two-port, it allow to choose preferable net realization from all solution set. Possibility to use uniform transmission lines give more technological net realization of broadband matching and filtering devices.","PeriodicalId":425905,"journal":{"name":"2006 8th International Conference on Actual Problems of Electronic Instrument Engineering","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123349203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
