Аннотация. Статья посвящена актуальной на сегодняшний день проблеме обработки томографических изображений при помощи вейвлет-анализа. Проанализированы особенности методов обработки изображений, показания, что вейвлеты -это волновая форма сигнала ограниченной длительности, которая имеет среднее значение ноль. Вейвлет сопоставим с синусоидальной волной; они являются основой анализа Фурье. Метод вейвлет-анализа позволяетпроизводить обработку томографических изображений с использованием большого временного интервала, где требуется более четкая информация о низкой частоте, и более короткие области, когда необходима информация о высокой частоте. Выделяются и описываются характерные особенностипо настройкам параметров вейвлет-преобразований, неудачный выбор которых снижает надежность выявления изменений структуры сигналов при изменении состояния системы. Рассматриваются ключевые этапы реконструкциитомографических изображений в формате DICOM при помощи методавейвлет-анализа;исследован алгоритм шумоподавления. Практическая область применения вейвлет-анализа не ограничивается цифровой обработкой сигналов; она также охватывает физические эксперименты, численные методы и другие области физики и математики. Благодаря способности анализировать нестационарные сигналы, вейвлет-анализ стал мощной альтернативой преобразованию Фурье в ряде медицинских приложений [4,5].Ключевые слова: выйвлет-анализ, преобразование Фурье, томография, шумоподавление.Abstract. The paper is devoted to the problem of processing of tomographic images using wavelet analysis. The features of image processing techniques, indications were analyzed. Wavelets are a signal waveform of limited duration that has an average value of zero. Wavelets are comparable to a sine wave, and they are the basis of Fourier analysis. Wavelet analysis method allows to processing of tomographic images using a large time interval, where more accurate information about the low frequency region and shorter when information is needed on high frequency. The characteristic features of the settings wavelet transforms are described. Their bad choice reduces the reliability of detection of changes in the structure of signals when changing system state. The key stages of the reconstruction tomography images in DICOM format using the method of wavelet analysis were examined; algorithm of noise reduction was investigated. Practical area of application of wavelet analysis doesn't limited to digital signal processing; it also covers physical experiments, numerical methods and other areas of physics and mathematics. By being able to analyze the non-stationary signals, wavelet analysis has become a powerful alternative Fourier transform in medical applications

The article considers the use of differentiated tasks during the training of younger schoolchildren on the lessons of Russian language in accordance with requirements of Federal State Educational Standards of Primary Education of second generation. The main attention is given to the development of speech culture of schoolchildren. The examples of tasks classification in accordance with the degree of complexity depending on the performance level of primary schoolchildren are given.

This article presents the results of the pilot study, based on the study of motivation parenting youth stage. As shown by theoretical analysis of the work of psychologists in parenthood psychology, motivation, parenting objective depends on purposeful activity in the development of this phenomenon. Of particular importance is the systematic activities for the establishment of parenthood at the stage of adolescence, because it is at this age level is observed intensification of the process of development of all the structures of the person, including its motivation, as well as value-orientation sphere. On the basis of the basic theoretical and methodological ideas we have designed and implemented a research program which not only confirmed the relevance of the development of this problem in relation to the stage of youth, but also objectively demonstrated the presence of significant differences in the manifestation of the motivation of parenting in the early and late periods of adolescence, as well as gender particular manifestations of this phenomenon. In particular, our research has shown that today´s young men and women to some extent, focused on the family, the birth of children and the realization of their parental roles. However, the development of a special developmental program that takes into account the specifics of motivation in the stage of parenthood early and late adolescence, as well as gender-specific manifestations of it, will ensure a higher level of conscious younger generation to do with their future children.
