Problems of multiprocessor computational structures applicability for spacecraft control systems

В работе рассматриваются основные проблемы проектирования резервированной вычислительной структуры для систем управления космическими аппаратами. Приводятся примеры существующих резервированных структур отечественной и зарубежной разработки, описываются их особенности и недостатки. Формулируются основные проблемы, возникающие при проектировании рассмотренных многопроцессорных структурно резервированных структур. Целью работы является анализ применимости трѐхканальной вычислительной структуры без отдельных модулей выборки решений в сравнении с существующими многоканальными системами. Предлагается трѐхканальный управляющий вычислитель, при разработке которого учитываются изложенные проблемы. Приведены особенности реализации программного обеспечения вычислителя, на которое возложены функции контроля неисправностей и нейтрализации отказов, возникающие в случайные моменты времени. Делается вывод об оптимальности использования вычислителя в системах управления космическими аппаратами.The paper presents the major problems of designing a redundant computing structures for spacecraft control systems. Examples of existing redundant structures of domestic and foreign design is presented, their features and drawbacks are described. The main problems encountered in the design of multiprocessor considered structural redundant structures are discussed. The aim is to analyze the applicability of computational three-processor structure without individual decision-making modules in comparison with the existing multiprocessor systems. It is proposed three-channel controlling evaluator, the design of which takes into account the described problems. Features of a evaluator software implementation, which is entrusted with the functions of control and fault neutralization failures occurring at random times are shown. The conclusion on the optimum use of the evaluator in the spacecraft control systems

Noninvasive method for determining the physical and mechanical characteristics of patients biological tissues

Morphological and biomechanical structure features of organs and tissues of the maxilla-facial area play the decisive role in the development of pathological processes and diseases. Understanding of their mutual influence while functioning and damage is one of the main points for a correct diagnosis, adequate treatment planning and rehabilitatio

Rozwój osobowości w naturalnych i utrudnionych warunkach

The paper is devoted to the features of personality development in physically challenged individuals, which is conceptualized as the development in complicated conditions, distinct from both normal and abnormal development. Goals, direction and criteria of the development in complicated conditions do not differ from the normal development case, but the deficit of a certain category of developmental resources requires extra mobilization of other resources and increases the efforts the individual needs to apply to attain the goals of development. The theoretical model proposed in the paper describes personality development through the mechanisms of interaction of bodily, social and personal resources, some of them compensating for the deficit of others. The developmental situation of the physically challenged individual is characterized by this very challenge; accepting it implies the construction of a specific system of activity regulation based on the compensation for the deficient bodily resources by virtue of personal resources. The character of this compensation largely depends on the availability of macrosocial and microsocial resources of social support.Artykuł poświęcony jest specyfice rozwoju osobowości osób z OMZ (ograniczone możliwości zdrowia), który rozumiany jest jako rozwój w utrudnionych warunkach, nie jest on tożsamy ani z normalnym, ani anomalnym rozwojem. Cele, ukierunkowanie i kryteria rozwoju w utrudnionych warunkach nie odbiegają od normalnego rozwoju, jednak deficyt określonej kategorii zasobów rozwoju wymaga podniesionej mobilizacji pozostałych zasobów i podnosi miarę wysiłków, które należy dostosować do indywiduum dla osiągnięcia celów rozwoju. Teoretyczny model, zaproponowany w artykule, opisuje osobowościowy rozwój przez mechanizmy współdziałania fizycznych, społecznych i osobowościowych zasobów, kompensacje deficytu jednych zasobów innymi. Sytuacja rozwoju osób z OMZ charakteryzuje się wyzwaniem niepełnosprawności, przyjęcie którego prowadzi do budowania u nich jakościowej figury systemu regulacji działania, opartego na kompensacji przez osobowościowe zasoby deficytu fizycznych środków, przy czym charakter tej kompensacji licznie  kształtuje się dostępnością makrospołecznych i mikrospołecznych zasobów pomocy społecznej

Quality assessment of endodontic treatment in patients, passed tomography examination in Belgorod

The purpose of root canals treatment is the maintenance (re-creation) of aseptic in the system of dentinal tubules, preventing the infection contamination of periapical tissues. Before the creation of cone-beam computed tomography, pre-operative estimation of the roots and periapical area, planned for operational impacts, had some difficulties, caused by projection distortion

Preclinical manifestations of students’ eating disorders as an impact of the information and communication university environment

Students’ eating disorders include conditions and diseases characterized by irregular foods intake accomplished by stable anxiety effect regarding the mass and shape of their bodies. Information and communicative university environment is able to create a motivation for eating disorders, which damages individual’s health and well-being. The most typical forms of students’ eating disorders affected both girls and boys, are nervous bulimia and anorexia nervos

The method of surgical access while treatment of nonclostridial anaerobic infections of soft tissues of tongue and oral cavity floor

The author analyzed the methods of operational interventions in the area of soft tissues of oral cavity floor and tongue while treatment of nonclostridial anaerobic infections. Twenty-nine of the forty-two analyzed patients were operated, using the authors’ method of T-shaped incision. The number of lethal outcomes has decreased almost twice. Treatment results allow us to recommend the proposed method for wider use in clinical practic

Estimation of stabilometric indicators with a decrease in the interalveolar distance

This paper presents the data of the estimation of stabilometric indicator in 293 patients with major dental diseases accompanied by a decrease in the interalveolar distance and 102 patients without signs of decreased occlusal vertical dimension. The cases with the habitual occlusion with signs of decreased occlusal vertical dimension show significant (P < 0.001) deterioration of the main indicators of the balance function. Optimization of the jaw relation has led to significant improvement of the coefficient of the equilibrium function and the area of the statokinesigram ellip
