В настоящей работе предлагается версия мозгового механизма возникновения и формирования перцептивного и психического образов. Начальным событием возникновения перцептивного образа является результат взаимодействия на релейных нейронах таламуса сенсорного хаотического импульсного потока и организованного в пачки импульсного потока, исходящего из ретикулярных структур. Последующий этап – это формирование метаустойчивого динамического объединения возбужденных колонок коры большого мозга. Рассматривается роль функционального объединения колонок коры и интрафузальной мышечной рецепции в активации распределённых систем мозга и формировании перцептивного образа. Этот образ рассматривается как метаустойчивое состояние синергичных процессов в нейро-мышечных структурах. Дается обоснование не воспринимаемости перцептивного образа. Предполагается, что основу психического образа составляют воспринимаемые эффекты ньютоновских сил, вызываемые сокращениями мышц. Обсуждаются свойства перцептивного и психического образов, их отличие и сопряженность. Роль психического образа во взаимодействии с образами сознания.
В статье рассмотрены философские и методологические аспекты эволюции учения о геосистемах – географических системах. Обращено внимание на нежелательные тенденции в этой эволюции, проявляющиеся в придании отдельным аспектам учения вида основополагающих принципов. Показана общенаучная диалектическая основа классического варианта учения о геосистемах, в том виде, как оно было разработано его основоположником – академиком В.Б. Сочавой. Подчеркивается несостоятельность разработанных позже и разрабатываемых в настоящий момент частных принципов учения о геосистемах как метанаучной парадигмы, относительная фундаментальность и жизнеспособность классических широко трактуемых, «несовершенных» понятий, позволяющих оперировать ими в широком круге аспектов географического (и не только) познания, в частности, на примере учения о геосистемах.
Вирус СOVID-19 унёс тысячи жизней. Породил мировой экономический и социальный кризис.
Цель статьи – привлечь внимание к управлению взаимодействием вируса и человека. Сформулированы следующие задачи. 1. Купирование (минимизация) активности вируса в организме человека. 2. Профилактика (минимизация) распространения вируса при максимизации экономического роста. 3. Использование сознания (динамических стереотипов) для формирования навыков защиты от вирусов, усиления иммунитета и использования вирусов с пользой для человека. 4. Постановка задачи сосуществования вируса (биосферы) и человека. Анализ этих задач позволил сформулировать варианты решений и представить на обсуждение механизмы реализации: базы врождённых и приобретённых навыков, методы самообучения и самоорганизации и практику сознательного созидания стереотипов. Некоторые из этих возможностей рассмотрены в этой статье.
Авторы разработали и успешно используют индивидуальную терапию на основе саморегуляции и центральной организации вегетативных функций. Исследовано формирование стереотипов и доминант в эксперименте на животных и в клинике при лечении.
Главный вывод: сегодня доминанта сознания людей акцентирована на социальных проблемах общества. Внутренней сфере практически нет места в сознании. Нужно переориентировать доминанту нашего сознания на решение задач внутренней сферы организма для сохранения баланса. В частности, во взаимодействии человека с СOVID-19.
Widespread introduction of mobile robotics in various spheres of human activity
makes the problem of mass disposal of expired, outdated and faulty robots topical. When disposing of
each type of mobile robots, it is necessary to take into account peculiarities of its design, composition
of on-board equipment and take into account environmental risks in case of destruction of the robot
structure with its fragments getting into the environment. Depending on the type and purpose of
robots, their disposal and recycling have significant features. This paper analyzes the problems
associated with the disposal of different types of autonomous mobile robots. The main sources of
environmental pollution present in the components of robots: electronic components, accumulator
batteries, constructional materials, connecting cables are considered. The environmental impact of
different types of mobile robots and the prevailing types of waste during their disposal are determined.

The following goals were set within the scientific work: to create a method, an
algorithm and a program for compression of raster (pixel) graphic information using special
mathematical methods, or affine transformations. The main task was to provide a high degree of image compression with a minimum deterioration of image quality. An original method for replacing a large number of pixel blocks in the source image by a relatively small number of the most suitable specially created domain blocks was developed. Affine transformation consists in moving any domain block from a set to any part of the image, while ensuring maximum similarity of source and domain blocks.
To implement the method, an algorithm and a program in the modern and popular Python language have been developed. We have considered the example of image transformation in grayscale of 256x256 pixels using domain blocks created from 4x4 pixel image areas. The result is an image visually indistinguishable from the original image, which requires only 0.3125 of the original information to describe. Calculations were also performed with a smaller number of domain blocks.
The developed method and program proved a high degree of compression of bitmap images with preservation of their quality. It is possible to further improve the described algorithm and the program presented on the author’s site by simultaneous application of different types of affine transformations.
It is shown that the same method can be used not only for image processing, but also for the detection of similarity (fractal properties) in any flow of information.
This paper analyzes artificial acoustical impact inside natural clouds, in particular inside the non-precipitated stratiform clouds, non-precipitating shallow cumulus clouds, and Cu-clouds with drizzle. Optimal power and frequency for acoustical impact were indicated based on properties of natural cloud, such as liquid water content, droplet concentrations, and the average diameter size of a droplet ensemble followed by lognormal or gamma size distributions in the presented consideration. The model is constructed to ensure collisions of neighboring droplets when they vibrate in acoustical field to merge with mass unification, but the process is designed with a minimum required level of acoustic power for comfort realization in practice. Vibration model of suspended droplets with typical size in cloud is analyzed. The optimized acoustic power is near 130 dB, and frequency f 50 – 100 Hz, and detailed characteristics are indicated for each cloud type depending on their parameters. Simple formulas and typical calculations for droplet amplitude are presented in terms of parameters of acoustical field as well as cloud characteristics. The first low-frequency acoustic experiments for clouds are performed and presented. The low-frequency method has shown a promising potential to be used for precipitation enhancement to tackle water shortage problem in the modern world.
Regularities of a production system development are discussed on the basis of the notion that progress in human economic activity is related to advances in the technological use of human effort and energy sources, which are regarded as the most important societal production resources. The concept of substitutive work of equipment P is introduced, which in all respects is equivalent to the efforts of people in production; it can be considered a service of capital, and is regarded as a value-forming factor, along with the traditional production factors. System output (value production) is defined as a function of three variables, two of which are: labour L and substitutive work P, are regarded as active sources of value, which allows us to introduce an energy measure of value, while physical capital K, as a production factor, plays a passive role. Under the assumption that the production system seeks to use all available social resources defined by circumstances external to the system, equations for production factors are formulated; they are also accompanied by equations for the technological characteristics of production equipment. The trajectory of the system development is determined by the characteristics of the system itself and the availability of social resources, which cannot be used completely simultaneously, which leads to a change of modes of development and fluctuations in output, i.e. business cycles. Using the example of the U.S. economy, it is demonstrated that the system of equations is able to describe the observed trajectory of development and output of the production system.
