The application of the BIM concept consists in the creation of an information model of the building, therefore the main thing is the information itself. The main point in working with large volumes of information (or data) is their arrangement to ensure the possibility of machine processing. For example, the possibility of selection by any criterion for making changes or summarizing data to automatic tables. During the work, an architectural project was created according to the drawings. All stages of the design of the interior design of the residential premises were worked out, the necessary documentation was created using BIM technology for construction and design work.

Study of the method for assessing atmospheric turbulence by the envelope of sodar signals

(2018) Sheiko, S.

The method for measuring the intensity of atmospheric turbulence based on assessment of statistical characteristics of the sodar signal envelope was investigated. This method requires no changes to the sodar hardware, but rather gives the possibility to make fuller use of echo-signals in order to obtain meteorological information. Through theoretical analysis, it was shown that the echo-signal envelope is distributed by the Rice law. The parameter of the law of envelope distribution is unambiguously associated with intensity of atmospheric turbulence. Assuming standard stratification of the atmosphere, the values of the parameter of the law of envelope distribution for four classes of atmospheric turbulence according to the ICAO classification were calculated: weak, moderate, strong and storm. Convergence of the experimental law of distribution of the envelope of acoustic echo-signals to the theoretical law at different measurement time was studied. It was experimentally determined that the theoretical and experimental laws of distribution of the sodar signal envelope mismatch with probability of less than 5 % at measurement time from 10 to 30 minutes. The results of measurement using this method converge to a stationary value at measurement time of more than 10 min. The use of the examined method for assessment of atmospheric turbulence in addition to already used methods will make it possible to increase accuracy and time resolution of sodars. Досліджено метод оцінки атмосферної турбулентності за статистичними характеристиками обвідної сигналів содара. Показано, що обвідна ехо-сигналів розподілена по закону Райса, параметр закону розподілу пов'язаний з інтенсивністю турбулентності. Отримані значення параметра закону розподілу ехосигналів для турбулентності певних класів. Використання дослідженого методу додатково до вже застосованих дозволить збільшити точність і часове розрізнення содарів.

Since ancient times, color was a strong, yet nevertheless, elusive force that determines human behavior. A large number of experiments have been carried out, many articles have been written and it is well known that the colors surrounding us are one of the most important factors in establishing a society. In a modern, fast-moving, urbanized world with a huge stream of information, the rate of suicide and depression is critical, there is a sharpening of social contradictions that are caused by individual psycho-emotional inconsistencies of people.

Получены значения коэффициентов подавления авторегрессионными фильтрами предсказания акустических помех, создаваемых самолетами. The models of autoregression are built and parametric spectra of acoustic noise, which take place during the operation of acoustic sounding systems in conditions of airport operation, are analyzed. Special attention is paid to the synthesis of autoregressive prediction filters for interference suppression. The values of the suppression coefficients are obtained by autoregressive filters for predicting acoustic noise generated by airplanes.

Адаптивный алгоритм сжатия изображений для создания пиксель-арта

(2018) Телюх, О. И.

Introduction of a content-adaptive image downscaling method for pixelart usage. The key idea is to optimize the shape and locations of the downsampling kernels to better align with local image features. Contentadaptive kernels are formed as a bilateral combination of two Gaussian kernels defined over space and color, respectively. This yields a continuum ranging from smoothing to edge/detail preserving kernels driven by image content. This is technically realized as an iterative maximum-likelihood optimization using a constrained variation of the Expectation-Maximization algorithm. The main task of this algorithm is creating pixel art images from raster or vector graphics inputs, due to its ability to keep linear features sharp and connected.

Адаптивный метод повышения помехозащищенности систем зондирования атмосферы

(2020) Рыбников, Н. В.; Капуста, А. И.; Нестеров, М. А.

The report shows that when constructing signal processing algorithms in sodars equipped with phased antenna arrays, it is advisable not only to form the distribution of zeros of radiation patterns in the directions to the sources of interference, but also to choose the radiation angles of the useful signal in order to minimize the interference power at the output of the array. The procedure for generating the interference power function at the output of the acoustic antenna array consists in forming the correlation matrix of the interference, its subsequent circulation, and the formation of the spatial spectrum of external acoustic interference on this basis. The directions of sounding the atmosphere will correspond with the directions in which the minimum values of the interference power at the output of the antenna array are observed.
