Design of non-linear filter in the problem of structural identification of biomedical signals with locally concentrated properties

In this paper we propose a generalized method of structural identification of biomedical signals with locally concentrated properties using a digital non-linear filter. The experimental verification of the detecting function was performed by using different ways to describe the model of the desired class of structural elements

Development of method of matched morphological filtering of biomedical signals and images

Formalized approach to the analysis of biomedical signals and images with locally concentrated features is developed on the basis of matched morphological filtering taking into account the useful signal models that allowed generalizing the existing methods of digital processing and analysis of biomedical signals and images with locally concentrated features. The proposed matched morphological filter has been adapted to solve such problems as localization of the searched structural elements on biomedical signals with locally concentrated features, estimation of the irregular background aimed at the visualization quality improving of biological objects on X-ray biomedical images, pathologic structures selection on mammogram. The efficiency of the proposed methods of matched morphological filtration of biomedical signals and images with locally concentrated features is proved by experiments

Some clinical aspects of prolonged clinostatic hypokinesia

Attendant problems which arise with prolonged confinement of patients to bed are discussed. These disorders are of a hyperkinesic nature, and the symptoms are treated with pharmacological substances

The Intelligent System of the Hearing Investigation

This paper describes a prototype of the intelligent system of the hearing investigation developed by the Tver State Technical University. The problem of automatic diagnostics, considered as the recognition problem of object not completely determined on set of the diseases classes’ descriptions, is discussed. The management strategy of the hearing investigation is proposed

Study of the Effect of Low-Temperature Plasma Exposure on Mould Fungi Colonizing Paper

The influence of radiofrequency cold plasma in ambient air at 200 Pa pressure on mould fungi of the genus Aspergillus was studied. It was shown that 20 min plasma treatment of paper with mould and contamination reduced the number of colony forming units but didn't lead to complete suppression of fungal viability. Strains of A. versicolor after plasma treatment lost the ability to excrete pink pigment to the environment. A. niger strains were more resistant and kept acidification ability. One of the possible plasma inactivation factors was formation of reactive hydroxyl (OH) radical

Ratings of The Investment Projects of Arbitrary Durations: New Methodology

In this paper we develop for the first time a new approach to ratings of the investment projects of arbitrary durations, which could be applied to investments of any area of economy and in particular to energy projects.The ratings of such energy projects, as "Turkish stream", "Nord stream-2", energy projects relating to clean, renewable and sustainable energy, as well as relating to pricing carbon emissions (McAleer et al., 2018a,b,c; 2019) could be done using developed here new rating methodologies. In our previous papers the new approach to the ratings of the long–term investment projects has been developed (Filatova et al., 2018). The important features of that consideration are as following: 1) The incorporation of rating parameters (financial "ratios"), used in project rating and playing a major role in it, into modern long–term investment models, 2) The adequate use of discounting of financial flows virtually not used in existing project rating methodologies. Here, for the first time, we incorporate the rating parameters (financial "ratios"), used in project rating, into modern investment models, describing the investment projects of arbitrary durations. This was much more difficult task then in case of the long–term investment projects, considered by us in previous papers. We work within investment models, created by authors. One of them describes the effectiveness of investment project from perspective of equity capital owners, while other model describes the effectiveness of investment project from perspective of equity capital and debt capital owners. New approach allows use the powerful instruments of modern theory of capital cost and capital structure (BFO theory) (Brusov et al., 2015, 2018) and modern investment models, created by the authors and well tested in the real economy to evaluate investment project performance, including energy projects.In our calculations we use Excel technique in two aspects: 1) we calculate WACC at different values of equity costs k0, different values of debt costs kd and different values of leverage level L=D/S, using the famous BFO formula; 2) we calculate the dependences of NPV on coverage ratios as well as leverage ratios at different values of equity costs k0, different values of debt costs kd and different values of leverage level L

A Systemic Approach to the Study of Children's Speech Disorders in the Works by Professor Z. A. Rerpina

В статье рассмотрены механизмы нарушения речи у детей с нарушениями артикуляционного аппарата, показана роль артикуляции и речевых кинестезий в формировании фонематической системы.The article analyzes the main results of the use of a systemic approach to the study of speech disorders in children in the scholarly papers of Professor Z. A. Repina. The review considers the mechanisms of speech disorders in children with articulatory disorders and clarifies the role of articulation and speech kinesthesias in the formation of the phonemic system. Based on the identification and analysis of the leading defects in the mechanisms of speech disorders in rhinolalia and dysarthria, the scholar demonstrates the significative function of the phoneme as a unit of the phonemic system and describes the possibilities of its study and formation through the semantics of a word, a sentence, and a text.In the formation of the phonemic system of children with impaired articulation apparatus, an important role is given to the development of phonemic awareness and phonemic analysis

Formation of reading skills in senior preschool children with dysarthria and visual analyzer disorders

The article presents the results of a study of reading skills of senior preschool children with dysarthria and visual analyzer disorders. The reading activity is interpreted as a purposeful process of interaction between the reader and the book the achievement of which results in the formation of reading independence. Based on the given research, it is shown that the structure of reading activity includes a sequence of operations: motivation, choice of material for reading, the process of reading proper, and reflection on what has been read.В статье представлены результаты работы по изучению навыков чтения у обучающихся подготовительной группы с дизартрией и нарушением зрительного анализатора

A study of professional motivation of students in the process of pastoral care

The article deals with the problem of studying professional motivation of students-defectologists in the process of pastoral work. In order to change the attitude towards people with disabilities on the part of society, the state implements the “Accessible Environment” program, within which social adaptation of people with disabilities takes place. One of the areas of activity under this program presupposes training of high-quality defectological personnel capable of ensuring the highest quality training and the most effective inclusion of people with disabilities in society. At the moment, there are certain requirements that are imposed on higher education institutions in training defec­tologists.В статье представлены методики изучения профессиональной мотивации студентов-дефек­тологов в процессе воспитательной работы в вузе
