The main criterion for considering algorithms is practical efficiency in solving optimization problems, in particular, the problem of finding the optimal route. We considered the genetic algorithm, the ant colony algorithm and the bee colony algorithm as algorithms that are promisingly suitable for introducing into the structure of an intelligent system for supporting evolutionary algorithms, we noted their advantages and disadvantages. We carried out a brief overview of software tools based on evolutionary algorithms, with an indication of their strengths and weaknesses, in particular, their focus on a specific algorithm. We developed a structural diagram of an intelligent system for supporting evolutionary algorithms, which is universal and not tied to a specific algorithm. The intelligent system consists of a set of modules: an interface module, a module for working with documents, a module for the mathematical core of EA support, a settings module, a module for generating an objective function, a help system module, a graphic module. We give a description of the functioning of each of them.

Oписана проблема существующих методов определения координат на этапе посадки летательного аппарата, которые имеют либо низкую точность, либо для реализации необходимо сложное оборудование. Поэтому были представлены особенности использования системы обеспечения посадки летательного аппарата с применением глиссадного лазерного маяка. Для осуществления посадки по лазерному глиссадному маяку необходимо дооборудование летательного аппарата системой технического зрения с помощью, c которой возможна автоматизация управления. В этом случае система технического зрения в полёте получает навигационную информацию о движении летательного аппарата в реальном масштабе времени. Осуществление посадки по лазерному маяку представленo путем математического моделирования процесса посадки по предложенному закону управления. Результаты моделирования показывают, что в конечной точке (точка касания взлетно-посадочной полосы) изменение высоты полета происходит плавно, что обеспечивает «мягкую» посадку. Движение осуществляется не по прямой, а по линии, близкой к экспоненте. Ввиду того, что работа с лазерными системами навигации оказывает воздействие на организм человека, был предложен безопасный способ использования данной системы и произведен расчет надежности функционирования. Предложенная система может быть применена на аэродромах любого класса и различных типах летательных аппаратов, на которых может быть установлено фотоприемное устройство и имеется система автоматического управления полетом в режиме посадки
This article describes the problem of existing methods for determining coordinates at the stage of landing an aircraft, which have either low accuracy or require complex equipment. Therefore, we present the features of using the system for ensuring the landing of an aircraft with the use of a glide path laser beacon. To land on a laser glide path, it is necessary to equip the aircraft with a vision system with the help of which control automation is possible. In this case, the technical vision system in flight receives navigation information about the movement of the aircraft in real time. We present the implementation of a laser beacon landing by mathematical modeling of the landing process according to the proposed control law. The simulation results show that at the end point (touchdown point of the runway), the flight altitude changes smoothly, which ensures a “soft” landing. The movement is carried out not in a straight line but along a line close to an exponential. In view of the fact that working with laser navigation systems has an effect on the human body, we propose a safe way of using this system and calculated the reliability of functioning. The proposed system can be applied at airfields of any class and various types of aircraft, on which a photodetector can be installed and there is an automatic flight control system in the landing mode

При этом приводятся два метода вычисления непрерывного вейвлет-преобразования на основе взаимно-корреляционной функции и на основе быстрого преобразования Фурье. Представлены результаты реализации данного алгоритма на различных графических процессорах (на одноплатных компьютерах с графическим ускорителем и дискретных видеокартах). Выполняются оценка скорости вычисления непрерывного вейвлет-преобразования от частоты дискретизации входного сигнала, оценка скорости вычисления непрерывного вейвлет-преобразования и метода периодограмм Уэлча от числа физических каналов, оценка скорости вычисления метода периодограмм Уэлча от количества частотных ячеек. Было произведено сравнение скорости выполнения двух методов вычисления непрерывного вейвлет-преобразования. Как показали проведённые исследования, среди рассмотренных графических процессоров наилучшие результаты продемонстрировала дискретная видеокарта Nvidia GTX1660 SUPER, которая позволила выполнить предложенный алгоритм за 32,5 мс. Показано, что данный алгоритм может применяться при анализе электроэнцефалограммы с целью определения ее частотного состава и локализации во времени ее основных видов особенностей (соответствующих патологии и артефактам)
In the work we describe the algorithm for performing time-frequency analysis of the signals using continuous wavelet transform together with the use of the Welch’s periodogram method. At the same time, we present two methods for calculating the continuous wavelet transform based on the cross-correlation function and on the basis of the fast Fourier transform. We give the results of the implementation of this algorithm on various graphics processors (on single-board computers with a graphics accelerator and discrete video cards). We performed the estimation of the computation speed of the continuous wavelet transform from the sampling frequency of the input signal, the evaluation of the computation speed of the continuous wavelet transform and the Welch periodogram method from the number of physical channels, the evaluation of the computation speed of the Welch periodogram method from the number of frequency cells. We compared the execution speed of the two methods for calculating the continuous wavelet transform. As the studies have shown, among the considered graphics processors, the best results were demonstrated by the discrete Nvidia GTX1660 SUPER graphics card, which made it possible to execute the proposed algorithm in 32.5 ms. We show that this algorithm can be used in the analysis of an electroencephalogram in order to determine its frequency composition and localization in time of its main types of features (corresponding to pathology and artifacts)

Published: July 2021

Современные электронные блоки во время работы подвергаются различным видам нагрузок, таким как вибрация и удары. Вибрационная нагрузка, как одно из условий нагружения электронных узлов, стала очень важным ключевым фактором в оценке надежности современных электронных систем. Проблема здесь заключается в том, как быстро и точно выполнить анализ усталостной долговечности при вибрации. Вибрация приводит к повреждению печатной платы и нарушению целостности паяных соединений из-за возникновения повышенного напряжения. Рассматривается методика, которая отличается от традиционных использованием взаимосвязи между способами нагрузки и фиксации платы. Методики, предлагаемые ранее, не принимали во внимание тип установки компонентов на плату и ее влияние на распределение напряжения на поверхности. Показана взаимосвязь между механическим напряжением и способами фиксации платы. Оценка усталостной прочности печатной платы, которая поможет аналитику сделать относительно точное прогнозирование вызванной усталостной долговечности. Процесс моделирования средствами PTC Creo Parametric включает четыре граничных условия (закрепление) платы, с целью определения оптимального метода фиксации с наименьшим напряжением. Кроме того, определение усталостной долговечности с помощью математических уравнений до начала фиксации снижает затраты и время
Modern electronic components are subjected to various types of stress during operation, such as vibration and shock. Vibration loading, as one of the conditions for loading electronic components, has become a key factor in assessing the reliability of modern electronic systems. The challenge here is how to quickly and accurately perform a vibration fatigue analysis. Vibration damages the PCB and compromises the integrity of the solder joints due to overvoltage. Here I considered the technique, which differs from traditional ones, using the relationship between the methods of loading and fixing the board. The techniques previously proposed did not take into account the type of component mounting on the board and its effect on surface stress distribution. I show the relationship between mechanical stress and board fixation methods. An assessment of the fatigue strength of a printed circuit board to help the analyst make a relatively accurate prediction of induced fatigue life. The PTC Creo Parametric modeling process includes four boundary conditions (clamping) for the board to determine the best clamping method with the least stress. In addition, the definition of fatigue life using mathematical equations before the start of fixing reduces costs and time

The Thue-Morse set $\mathcal{T}$ is the set of those non-negative integers whose binary expansions have an even number of $1$'s. The name of this set comes from the fact that its characteristic sequence is given by the famous Thue-Morse word
$${\tt 0110100110010110\cdots},$$
which is the fixed point starting with ${\tt 0}$ of the word morphism ${\tt 0\mapsto 01}$, ${\tt 1\mapsto 10}$. The numbers in $\mathcal{T}$ are commonly called the evil numbers. We obtain an exact formula for the state complexity of the set $m\mathcal{T}+r$ (i.e. the number of states of its minimal automaton) with respect to any base $b$ which is a power of $2$. Our proof is constructive and we are able to explicitly provide the minimal automaton of the language of all $2^p$-expansions of the set of integers $m\mathcal{T}+r$ for any positive integers $p$ and $m$ and any remainder $r\in\{0,\ldots,m{-}1\}$. The proposed method is general for any $b$-recognizable set of integers.
