Moscow Institute of Electronics and Mathematics, MIEM (Russian: Московский институт электроники и математики НИУ ВШЭ, МИЭМ; also occasionally referred to as Moscow Institute of Electronic Engineering) — a Russian higher educational institution in the field of electronics, computer engineering, and applied mathematics..
Работа посвящена сравнительному анализу скорости расчета схемных симуляторов NGSPICE, LTspice, NGSPICE с использованием оболочки Python при электротепловом моделировании схем, а также анализу применения ПО Python для автоматизации SPICE-симуляций с использованием цифровых двойников компонентов электронных схем с учетом влияния на них внешней температуры. Проанализированы различия в смоделированных переходных характеристиках и затратах времени на моделирование для ряда схем, связанных с использованием разных методов вычисления, лежащих в основе каждого из перечисленных выше SPICE-симуляторов.
Рассмотрим последовательности целых чисел 𝑎(𝑘,𝑗)𝑛 , 𝑗 = 1, ..., 𝑚, 𝑘 = 1, ..., 𝑇𝑗 , удовлетворяющие условиям 𝑎(𝑘,𝑗)𝑛 = 𝑎(𝑘,𝑗)𝑛+𝑇𝑗, 𝑗 = 1, ..., 𝑚, 𝑘 = 1, ..., 𝑇𝑗 , 𝑛 = 0, 1, ... и рассмотрим функции 𝐹𝑗,𝑘(𝑧) =∞Σ︁𝑛=0𝑎(𝑘,𝑗)𝑛𝑛!𝑧𝑛, 𝑗 = 1, ..., 𝑚, 𝑘 = 1, ..., 𝑇𝑗 . В работе устанавливаются условия, при которых совокупность функций 1, 𝑒𝑧, 𝐹𝑗,𝑘(𝑧), 𝑗 = 1, ..., 𝑚, 𝑘 = 2, ..., 𝑇𝑗 линейно независима над C(𝑧) и для любого рационального числа 𝛾 ̸= 0 их значения в точке 𝛾 линейно независимы. Получена оценка меры линейной независимости этих чисел.Результат может быть использован при построении псевдослучайных чисел.
The article about contradictions of struggle against social groups’ discrimination. Traditionally discrimination refuse is one of basic democracy values. However, facts of anti-discrimination struggle extension to private life introduces to such a struggle totalitarian tendencies. No less importance has tendencies to transformation human rights ideal into ideological construct on which base justified opposition ideology discrimination.
In this paper, a computer simulation of round wire drawing processes with different equations of state for steel A12 has been carried out. In addition, the methods of improving the configuration of neural networks based on a multilayer perceptron (MLP) for estimating the distributions of residual stress tensor components have been investigated. The study demonstrated that the strain rate exerted a significant influence on the character of the processes, particularly within the central region ( 0r-0.4r ) of the investigated specimens. In addition, the employment of software tools for the purpose of tuning the hyperparameters of trained machine learning models, including Optuna, BayesianOpt, and Skopt, has been demonstrated to enhance the predictive capability of the models. Consequently, this results in an improvement in the accuracy of the obtained distributions of the required characteristics.
The article is dedicated to the study of new influence marketing tools and their application in business activities. It emphasizes that influence marketing is a method of promotion through opinion leaders (influencers) and their audiences. The significance of influence marketing as a tool for strengthening brands, attracting audiences, and increasing sales by building trust with the target audience is highlighted. The article discusses key trends in the development of influence marketing and conducts a SWOT analysis of its application in the business context. New formats of influence marketing are identified, including short videos, live streams, textual and visual content, and exclusive materials. These, along with modern analytics tools, ensure improved quality of audience interaction and stimulate sales. As a result of the research, the practical significance of influence marketing for businesses is underscored, considering its impact on promotion.
