    In the article, on the basis of the concept of "display" of geometry of a free surface of the "low-magnetic" environment by the topography of isolines of the module of intensity of a magnetic field, it is studied a form of a free surface of magnetic fluid in a static condition at the initial stage of rapprochement of a ring magnet with a surface of a column of magnetic fluid in a tube and at a stage of pressing of a cavity to a bottom. It is shown that the separation of bubbles from an air cavity occurs in close proximity to the plane of symmetry of a ring magnet on its axis. It is described the method and experimental installation for studying the possibility of electromagnetic indication of sizes of the air bubbles, being in magnetic fluid. It is discussed the results of experimental research on process of a separation of solitary air bubble from a cavity, contained in magnetic fluid and squeezed by ponderomotive forces of a magnetic field which are of interest for creation of essentially new technique of the dosed supply of small amount of gas in the reactor.

    В работе рассматривается модификация имитационной модели прогнозирования процессов развития региональной макроэкономической системы с помощью построения искусственной нейронной сети – многослойного персептрона с парадигмой «обучение с учителем». Для данного типа сети формируется вектор входных данных, выбирается функция активации и алгоритм обучения. Многослойный персептрон позволит решать задачу определения параметров, которые используются для формирования параметров и переменных при прогнозировании последствий проводимой государственной политики.У роботі розглядається модифікація імітаційної моделі прогнозування процесів розвитку регіональної макроекономічної системи за допомогою побудови штучної нейронної мережі − багатошарового персептрона з парадигмою «навчання з учителем». Для даного типу мережі формується вектор вхідних даних, вибирається функція активації та алгоритм навчання. Багатошаровий персептрон дозволить вирішувати завдання визначення параметрів, які використовуються для формування параметрів та змінних моделі при прогнозуванні наслідків проведеної державної політики.The paper deals with the process of modification the simulation model forecasting development processes of regional macroeconomic systems by constructing an artificial neuron network − a multilayer perceptron with the paradigm of "learning with a teacher". For this type of network is formed the vector of input data, is selected the activation function and the learning algorithm. The multilayer perceptron will solve the problem of determining the parameters that are used to form the parameters and variables of the model in predicting the effects of state policy
