53. Comparison of different wavelets efficiency for electroencephalogram analysis [№2 за 2013 год]

Abstract: The article provides a comparative evaluation of WAVE and Morlet wavelets application in continuous wave-let transformation of medical and biological signals. Using Morlet wavelet application in real time processing the EEG data is difficult. That is why the possibility of replacing it with the WAVE wavelet without significant loss of information content of the coefficients matrix of the wavelet transformation was analyzed. The article proves the replaceability of the Morlet-wavelet with the Wave-wavelet in EEG processing. From henceforth the construction of matrix local maximums W2(a, b) string (LMS) forming EEG is possible. Under some conditions associated with registered signal duration and LMS drift in frequency domain, this replaceability is possible. In case of LMS analyzing in time domain and researching LMS drift in fre-quency domain with high resolution, the substitution is incorrect. It limits using Morlet-wavelet in real-time systems for EEG analysis.

Abstract: The article describes the simulation software of the human hypoxic conditions dynamics according to health risk metrics and human performance in terms of low barometric pressure (high altitude flights, mountaineering, space, etc.). The hypoxia dose mathematical model as the integral intensity of hypoxic impact within the time of this factor activity allows passing into the dynamic area of study the effects of hypoxic gas environment (to size up its impact on the human condition in real time). It allows calculating the buffer time of human efficiency saving in conditions of hypoxic hypoxia and recovery time after cut -off of. The developed model provides calculation of probabilities adequate valuation of adverse effects with any velocity profiles and oxygen partial pressure in a trachea, multiplicities and exposure time of hypoxic outward influence. A mathematical model verification based on the results of computer simulation using data from real aircraft cabin depressurization incident with the Tu-154. These results provide decision support when choosing the optimal flight path of aircrafts in the case of cabin depressurization, in assisting the injured and affected in emergencies in the high altitude and in a number of other problems associated with the presence of human beings in hypoxic hypoxia.

Abstract: Various technical object diagnostic systems and process control systems based on the diagnostic results are widely spread in different fields of industry. In most optical inspection systems and diagnostic system of details and construc-tions control and diagnostic processes are represented as analysis of half-tone monochromatic images of item structure. The use of X-ray films underlie defectoscopy radiographic method which is the most prevailing of all well-known radiation con-trol methods. There is an essential disadvantage of the method: under the influence of primary radiation energy scattered radiation changes quality of image, reduces its hardiness and sharpness, so the method doesn’t appear to be sensitive. Due to this effect small-size defects are hardly detected. It is considered that the quality of spot welded joints may be improved by means of their X-ray analysis automation. Pop-ular analysis and image processing systems (Adobe Photoshop, Paint.NET, GIMP ) were analyzed along with their applica-bility to the problem of the analysis of spot welded joints digitized X-rays. There is a table of programs features comparison in the field of consideration. SOWA 193 scanned X-ray analysis pro-gram and such expert systems as ImageExpert and Ident Smart Studio are separately regarded. The conclusions about the existence of topical problems concerning X-ray analysis and existence of full bundled software applicable to X-rays are made.

56. The algorithm and program for calculating the sands stress-strain state under cyclic loading [№2 за 2013 год]
Authors: () - , Ph.D; (sofjin@mail.ru) - , Ph.D;
Abstract: A numerical model of non-cohesive soil deformation calculating is developed On the basis of modern elasticplastic Dafalias-Manzari model, implicit Euler method and the iterative Newton-Raphson scheme. The numerical implementation of the model on the computer is executed. The simulation of the sand behavior at a monotonic and cyclic loading is carried out. The calculation data and experimental information for sand with various compactness were compared. The computational model definitely describes sand behavior with monotonic and cyclic loading. The results of the theoretical prediction of the sands stress-strain state under monotonic and cyclic loading show the efficiency of the computational algorithm. They allow recommending this prediction for finite-element analysis for geotechnical problems solving.
