Homogenisation method based on energy conservation and independent of boundary conditions

The foundation of homogenisation methods rests on the postulate of Hill–Mandel, describing energy consistency throughout the transition of scales. The consideration of this principle is therefore crucial in the discipline of Digital Rock Physics which focuses on the upscaling of rock properties. For this reason, numerous studies have developed numerical schemes for porous media to enforce the Hill–Mandel condition to be respected. The most common method is to impose specific boundary conditions, such as periodic ones. However, these boundary conditions influence both the effective property and the size of the REV. The recent study of Thovert and Mourzenko (2020) has shown that most boundary conditions still result in the same intrinsic effective physical property if the averaging is applied outside the range of the boundary layer. From this discovery, it becomes logical to question the status of Hill–Mandel postulate in porous media when homogenising away from the boundary. In this contribution, we simulate Stokes flow through random packings of spheres and a range of rock microstructures. For each, we plot the evolution of the ratio micro- vs macro-scale of the energy of the fluid transport outside the boundary layer, for a growing subsample size of porous media. Here, we prove that we naturally find energy consistency across scales when reaching the size of the Representative Elementary Volume (REV), which is a known condition for rigorous upscaling. Furthermore, we show that this index for the energy consistency is a more accurate indicator of REV convergence since the mean value is already known to be unitary.

The essence of using problem-based learning technologies in teaching physical education disciplines

This article discusses the direction of improving the quality of training of professional teaching personnel using problem-based learning technologies when conducting physical education classes. The main difference between problem-based and traditional learning is seen in the goals and principles of organizing the educational process. The goal of problem-based learning is to master not only the fundamentals of science, but also the process of acquiring knowledge and scientific facts, and the development of the student’s cognitive and creative abilities. Problem-based learning, like any other teaching method, is not universal, but it is an important part of the modern education system. Physical education is one of those subjects that can implement these approaches in its lessons, and problem-based learning will help achieve the main goal of education and training. This method contributes to the development of the ability to apply one’s knowledge in different situations, helps to study phenomena from different sides and in different aspects, that is, it contributes to the formation of critical thinking.

Construction and Evaluation of an Intelligent Analysis System for Interactive Teaching in Physical Education Classrooms

Abstract With the continuous deepening and progress of the research in the physical education discipline, the school and the state put the landing point on the integration of information technology and the development of the discipline. In this paper, we design the system framework and perform data module design, on the basis of which we conduct detection research on teacher-student interaction behavior. The article employs an intelligent analysis system based on the YOLOv5 model to establish a model of teacher-student interaction behavior. This model is based on the movement and facial observations of both teachers and students in a physical education classroom. The intelligent analysis system, based on the YOLOv5 model and independent t-test, observed the behavior of teacher-student interaction based on the ratio of teacher-student verbal interaction and analyzed it accordingly. In teacher- and student-type speech, the ratio of teacher-direct influence speech is 45.62%, which is higher than indirect influence speech, while the ratio of student-passive speech is 5.54%, which is higher than student-active speech. Finally, the interactive intelligent system was evaluated for teaching and learning to understand students’ feedback on the intelligent analyzing system based on the YOLOv5 model from two parts: physical education test scores and students’ satisfaction surveys. In the physical education classroom, the teacher primarily uses their own words and interacts with the students less frequently. However, the system has the potential to significantly enhance students’ performance in Physical Education, with the majority of students reporting improvements in their PE skills and other areas. In terms of participation in the physical education classroom, 32 students thought that there was a “great improvement,” and 22 students thought that there was an “improvement,” for a total percentage of 98.18%, which is a significant effect.

UnDrift: A versatile software for fast offline SPM image drift correction.

Scanning probe microscopy (SPM) techniques are widely used to study the structure and properties of surfaces and interfaces across a variety of disciplines in chemistry and physics. One of the major artifacts in SPM is (thermal) drift, an unintended movement between sample and probe, which causes a distortion of the recorded SPM data. Literature holds a multitude of strategies to compensate for drift during the measurement (online drift correction) or afterwards (offline drift correction). With the currently available software tools, however, offline drift correction of SPM data is often a tedious and time-consuming task. This is particularly disadvantageous when analyzing long image series. Here, we present unDrift, an easy-to-use scientific software for fast and reliable drift correction of SPM images. unDrift provides three different algorithms to determine the drift velocity based on two consecutive SPM images. All algorithms can drift-correct the input data without any additional reference. The first semi-automatic drift correction algorithm analyzes the different distortion of periodic structures in two consecutive up and down (down and up) images, which enables unDrift to correct SPM images without stationary features or overlapping scan areas. The other two algorithms determine the drift velocity from the apparent movement of stationary features either by automatic evaluation of the cross-correlation image or based on positions identified manually by the user. We demonstrate the performance and reliability of unDrift using three challenging examples, namely images distorted by a very high drift velocity, only partly usable images, and images exhibiting an overall weak contrast. Moreover, we show that the semi-automatic analysis of periodic images can be applied to a long series containing hundreds of images measured at the calcite-water interface.

Embodiment of Core Literacy in Physical Education and Health Courses in Colleges and Universities in the Information Age

Abstract Based on the relevance topic model and density clustering, this paper constructs a college sports health theme model. The framework of physical education discipline literacy was created by combining the standard of discipline core literacy with the framework. The core of the physical education and health curriculum was judged by calculating the maximum likelihood function of the core literacy in the curriculum and the multiple embodiment variables in the curriculum. Combining the variational EM algorithm to calculate the edge likelihood function of the data, the hidden variables in the core literacy of physical education and health courses were identified and solved. This paper focuses on the analysis of students’ athletic ability, healthy behavior and physical morality in physical education course teaching and explores the core literacy of physical education from two aspects: teaching objectives and teaching evaluation. The results showed that the classification accuracy of the topic model for exercise ability, health behavior and sports morality in college physical education and health courses was 0.927, 0.831 and 0.857, respectively. According to the statistics of students’ weekly physical exercise, 467 students met the evaluation criteria of the physical education population, accounting for 49.5% of the total number of students, indicating that most of the students in colleges and universities had good physical exercise habits. The teaching efficiency of physical education and health courses in colleges and universities was improved to some extent by this study.

Research on Physical Education Management System in Higher Education Institutions in the Context of Deep Learning

Abstract This paper focuses on the management of physical movement sports disciplines and combines relevant algorithms to design an artificial intelligence-based physical education management system framework. In terms of related algorithms, the first is for the research of character recognition algorithms. Considering the intra-class differences between individual movements, the LR-based feature extraction algorithm is proposed. Secondly, for the research of the action evaluation algorithm, the statistical value, DTW parameter action time series difference and correlation coefficient based on the statistical value and DTW parameter are used as the features, combined with SVM-based feature extraction algorithm for perceiving the action differences. Finally, with the help of deep neural networks for movement analysis, we can improve students’ movement techniques during training. In the course schedule supported by the system, the proportion of moderate-intensity exercise time is high, basically, more than 40%, which meets the WHO requirements for high-intensity exercise time in physical education classes. The post-course RPE feedback from students was spread out between 12 and 15, and the highest post-course RPE value was 14.82<unk>1.38, which was evaluated within a reasonable range of intervals. The teaching management system in this paper can meet the requirements of physical training and teaching, and provide quantifiable basis and management tools for the informatization and precise teaching of physical movement subjects.

International mobility characteristics, effects of, and effects on elite scientists

Understanding the international flows of elite scientists is critical to science and talent policies. In this study, using the Scopus data of 78,815 top h-index scientists between 1921 and 2020, we investigate the characteristics of the international mobility of elite scientists, including geographic features, mobility types, and disciplinary characteristics. Our results reveal an increasing number of countries participating in international mobility over the past 2 decades, with North America and some Western European countries still serving as centers. Emerging economies have also become important mobility hubs in recent decades. Mobile scientists who have returned to their home countries have become the dominant mobility type, mainly in the form of short-term mobility. The disciplines of physics and astronomy and engineering have larger shares of mobile scientists than other disciplines, and the average flow frequency of elites varies among 26 observed disciplines. We use a difference-in-differences model to analyze how global mobility affects the individual productivity of elite scientists by distinguishing flow paths. The results indicate that international mobility improves the research performance of elite scientists who move to more scientifically advanced countries and that research quality is most positively impacted when elite scientists move to the United States or move from China.

The article examines theoretical-scientific problems and shows the peculiarities of the formation of STEM competence of all participants in the educational process when studying physical and mathematical disciplines and natural sciences. When analyzing theoretical and practical data, we developed our own definition of STEM competence and formed the main components and levels that future physics teachers can master in the process of introducing into the educational process various applied programs, robotics tools, virtual laboratories, specialized software and hardware, and as well as their practical activities. Thus, introducing STEM competence solves many issues, such as issues of innovation and creativity, communication, critical thinking, cooperation, selfregulation, pedagogical and psychological skills. Given that STEM is a controversial, context-specific concept in various scientific and technological fields, this set of skills will help all participants in the modern educational process to have the same understanding of the educational field and its intended purpose.

The nonlinear wave dynamics of fractional foam drainage and Boussinesq equations with Atangana’s beta derivative through analytical solutions

The space–time fractional foam drainage and the Boussinesq equations are valuable mathematical models to describe different complex physical phenomena, including the drainage of soap films in bubbles and foams, the behavior of surface water waves in oceans and rivers, the propagation of long waves, etc. In this research, we explore several unrivaled and some existing analytical soliton solutions to the above-stated equations using an effective expansion scheme, known as the G′/(G′+G+A)-expansion scheme within the framework of Atangana’s beta derivative. A fractional composite transformation is used to interpret the considered equations into nonlinear equations of a single independent variable. The wave dynamics of the outcomes are illustrated through three- and two-dimensional graphical representations and contour plots. The solutions include kink, flat kink-shaped, the parabolic-shaped, the bell-shaped, and the compacton solitons. The study reveals that the fractional-order derivative in the projected equations influences the wave behavior, providing deeper insights into wave composition when the fractional derivative approaches larger. The comparison table demonstrates the effectiveness of the method across various fractional orders, with results approaching accuracy as the fractional-order approaches integer values. This study emphasizes the computational robustness and adaptability of the proposed method for investigating various phenomena across a wide range of physical science and engineering disciplines.

Had-Had Pukulan Yang Dibenarkan Terhadap Isteri Menurut Al-Quran Dan Hadis

Happiness in marriage has a significant impact and is capable of preventing undesirable occurrences. Having a happy family is a dream for every individual. Through marriage, a feeling of happiness known as "al-sa‘adah" is born. It is the duty and responsibility of the husband to educate his wife to obey all of Allah's commands. The Quran and Hadith serve as a comprehensive guide for humanity, encompassing all matters, including the management of marriage. Unfortunately, not all marriages provide the happiness envisioned by every married individual. A husband is permitted to strike his wife with the intention of educating and teaching for her betterment, not to vent anger or seek revenge. To what extent such physical discipline is considered permissible according to Islamic law is explored. The objective of this study is to examine the permissible limits of physical discipline on wives according to the Quran and Hadith. The research design is qualitative, utilizing document analysis as the data collection method, and textual analysis as the data analysis method. The findings of the study reveal that there are limits and guidelines permitted for disciplining wives according to Islamic law.

Moksha in the Religious Philosophy of Ancient India: A View from Vietnam

One of the many outstanding themes found in ancient religions of India is the theme of Moksha or liberation. With time, Indian society changed and man’s mental power also improved. The philosophical thought of Liberation first started between the time of the Rig-Veda (from 1500 B.C to 1000 B.C.) and that of Brahmanas (from 1000 B.C to 800 B.C to 500 B.C), was further developed in the principal message of the Upanishads (from 800 B.C to 500 B.C.) and interpreted differently in the various philosophical and religious schools of the time such as Sankhya, Vaisheshika, Nyaya, Yoga, Mimansa, Vedanta (belonging to orthodox Brahminism) or Jainism. This thought, however, reached its highest development in Buddhism (of the unorthodox system). Each of these philosophical and religious schools, together with its teachings and tendencies, represented the voice of each of the various castes in India and presented a course of physical and mental disciplines for attaining liberation.
