Aim To test a hypothesis that increased values of red cell distribution width (RDW) in patients with chronic heart failure (CHF) can be related with low exercise tolerance.Material and methods 102 patients were evaluated who had CHF with mid-range and reduced left ventricular ejection fraction (LV EF) without anemia (72% men, mean age 66±10.2 years). Cardiopulmonary stress test (CPST), echocardiography, 6‑min walk test (6MWT), blood count, and measurements of N-terminal pro-brain natriuretic peptide (NT-pro-BNP) and serum iron were performed.Results The average LV EF was 39±8.7 %; the peak oxygen consumption (VO2peak) was 13.7±4.8 ml /kg /min; and the median NT-pro-BNP was 595.3 pg /ml (Q1–3 1443–2401). RDW variables, including the RDW coefficient of variation (RDW-CV) and RDW standard deviation (RDW-SD), were not significantly related with serum iron or hemoglobin concentrations. A one-factor linear regression analysis showed a significant correlation of VO2peak with RDW-SD (р=0.039). A multivariate linear regression analysis with adjustments for LV EF, hemoglobin concentration, and age did not reveal any significant correlation of VO2peak with RDW variables. The distance covered in the 6MWT was significantly associated with RDW-CV both in the one-factor analysis and with adjustments for LV EF, hemoglobin and serum iron concentrations, and age.Conclusion This study showed that high RDW values in CHF patients without anemia predicted low exercise tolerance regardless of the age, LV systolic function, and hemoglobin and serum iron concentrations. A 16% increase in RDW-CV significantly decreased the likelihood of covering a distance longer than 360 m during 6 min.

Комплексирование инерциальной навигационной системы и глобальной навигационной спутниковой системы призвано обеспечить надежной, безопасной и устойчивой работоспособностью навигационные системы воздушного судна. Для достижения этого целесообразно подчеркнуть следующие требования: поддержание/обеспечение/сохранение точности параметров навигационных систем при длительной работе; обеспечение простоты и надежности алгоритма комплексирования навигационной системы, требующей низкой производительности обработки бортовыми компьютерами воздушного судна. Для удовлетворения вышеперечисленных требований применяется централизованный метод фильтра Кальмана, использующийся для компенсированной интеграции глобальной навигационной спутниковой системы и инерциальной навигационной системы в условиях слабой связи. Этот метод комплексирования, во-первых, довольно компактен в реализации, что значительно сокращает объем вычислений и упрощает сложность системы. Во-вторых, погрешность навигационных параметров инерциальной навигационной системы, вычисляемая алгоритмом дискретного фильтра Кальмана, возвращается в систему методом корректировки обратной связи, что устраняет проблему снижения точности навигационных параметров после длительной работы. Результаты этой работы представлены моделированием погрешности по скорости и положению воздушного судна в полете после фильтрации. Проверена устойчивость и эффективность предложенного алгоритма.
The integration of an inertial navigation system and the global navigation satellite system is designed to ensure reliable, safe and stable performance of aircraft navigation systems. To achieve this, it is advisable to emphasize the following requirements – maintaining / ensuring /preserving the accuracy of the parameters of navigation systems during long-term operation; ensuring the simplicity and reliability of the algorithm for integrating the navigation system, which requires low processing performance by on-board computers of the aircraft. To meet the above requirements, a centralized Kalman filter method was used, used for integration of global navigation satellite system and inertial navigation system systems in conditions of weak communication/signals. Firstly, this integration method is quite compact in implementation, which significantly reduces the amount of calculations and simplifies the complexity of the system. Secondly, IN Snavigation parameters error is calculated using the discrete Kalman filter algorithm, is returned to the system by the feedback correction method, which eliminates the problem of reducing the accuracy of navigation parameters after prolonged operation. The results of this work are depicted by modeling the error in aircraft navigation parameters in flight after filtering. The robustness and effectiveness of the proposed algorithm has been tested.

Представлены результаты компьютерного моделирования и прогнозирование механических свойств композитных материалов с поликарбонатной и полиамидной матрицей, наполненной короткими стеклянными включениями разной формы. Композитный материал будет использоваться для производства рабочего колеса насоса, поэтому должен обладать заданными механическими свойствами, а именно: уровень напряжений, возникающих в поперечном сечении колеса, должен достигать уровня 85 МПа. В программе DIGIMAT спрогнозированы уровни напряжений и инженерные характеристики материалов с полиамидной и поликарбонатной матрицей. На микроуровне исследовано влияние объема включений на механические свойства проектируемого композита. Установлено, что при соотношении размеров включений в пределах 468…60 частицы имеют игольчатую форму, и у материала с такими включениями предел напряжений и модуль упругости выше, чем при коэффициенте формы меньше 50, то есть когда форма включений приближена к сфере, и уровень прочности при такой форме достигает только 90 МПа.
The essay represents the results of computer modeling and prediction of mechanical properties of composite materials with polycarbonate and polyamide matrix filled with short glass inclusions of different shapes. The composite material will be used for the production of the pump impeller and mechanical properties should have the level of stresses arising in the cross section of the wheel in 85 MPA. The DIGIMAT program predicts stress levels and engineering characteristics of materials with polyamide and polycarbonate matrices. The influence of the volume of inclusions on the mechanical properties of the designed composite is investigated at the micro level. Moreover, it was found that with a ratio of the sizes of inclusions in the range of 468÷60, the particles have a needle shape and the material with such inclusions has a stress limit and elastic modulus higher than with a shape coefficient less than 50, in case, when the shape of the inclusions is close to the sphere and the strength level in this form reaches only 90 MPA.

Рассмотрены современные способы моделирования движения лавиноопасных снежных масс. Представлены результаты вычислительного эксперимента по моделированию движения снежной массы с позиций законов динамики поступательного движения. В рамках метода динамики частиц снежную массу представляли в виде совокупности одинаковых шарообразных элементов диаметром около 0,1 м. Показано, что трехмерная модель на основе динамики частиц позволяет получить высокую степень пространственной и временной дискретизации, что, в свою очередь, обеспечивает расчет траектории движения, энергии, давления снежной лавины. Таким образом, объемная дискретная модель снежной массы позволяет адекватно оценить разрушительное воздействие лавин.
The article discusses modern methods of modeling the movement of avalanche-prone snow masses. The results of a computational experiment on modeling the movement of a snow mass from the standpoint of the laws of the dynamics of translational motion presented. Within the framework of the particle dynamics method, the snow mass was represented as a set of identical spherical elements with a diameter of about 0.1 m. It shown that a three-dimensional model based on particle dynamics allows obtaining a high degree of spatial and temporal discretization, and this in turn provides calculation of the trajectory of motion, energy, and pressure of an avalanche. Thus, the volumetric discrete model of the snow mass allows us adequately assess the destructive impact of avalanches.

Работа посвящена исследованию возможностей численного решения задач вычислительной гидродинамики для трехмерного уравнения диффузии-конвекции на основе использования схем расщепления. Предполагается замена исходной задачи цепочкой двумерных и одномерных задач:для аппроксимации двумерной задачи диффузии-конвекции по горизонтальным направлениям – использование явной разностной схемы, для аппроксимации одномерной задачи диффузии-конвекции по вертикальному направлению – неявной схемы. Особое внимание уделено описанию механизмов численного решения двумерного уравнения диффузии-конвекции. С этой целью применены схемы, построенные на основе линейной комбинации разностных операторов схем «кабаре» и «крест» с весовыми коэффициентами, полученными в результате минимизации порядка погрешности аппроксимации. Предлагаемые в работе схемы расщепления являются физически оправданными и обладают свойством устойчивости. В рамках программной реализации параллельного счета представлен параллельный алгоритм, реализующий трехмерную задачу гидродинамики и переноса веществ на многопроцессорной вычислительной системе с использованием гибридной технологии MPI+OpenMP. Выполнено сравнение эффективности расчетов, проводимых на основе технологии MPI и гибридной технологии MPI+OpenMP.
The work is devoted to the study of the possibilities of the numerical solution of computational fluid dynamics problems for the three-dimensional diffusion-convection equation based on the use of difference schemes of a special type - two-dimensional - one-dimensional splitting schemes. Under these assumptions, it is assumed that the original problem is replaced by a chain of two-dimensional and onedimensional problems. To approximate the two-dimensional diffusion-convection problem in horizontal directions, it is assumed to use an explicit difference scheme, and to approximate the one-dimensional diffusion-convection problem in the vertical direction, an implicit one. Particular attention is paid to the description of the mechanisms for the numerical solution of the two-dimensional diffusion-convection equation. For this purpose, schemes are applied, built on the basis of a linear combination of difference operators of the “cabaret” and “cross” schemes with weight coefficients obtained as a result of minimizing the order of the approximation error. The splitting schemes proposed in this work are physically justified and have the property of stability. As part of the software implementation of parallel computing, a parallel algorithm is presented that implements the three-dimensional problem of hydrodynamics and the transfer of substances on a multiprocessor computer system using the hybrid technology MPI + OpenMP. Comparison of the efficiency of calculations based on MPI technology and hybrid MPI + OpenMP technology is carried out.
