These Identity design has been an important subject of human concern since ancient times. In ancient feudal society, the same group of people formed a pyramid structure. Taking the Qing Empire as an example, the emperor's robe is yellow with a dragon emblem embroidered on it, symbolizing the emperor's majesty, while the official robes are divided into bird patterns and animal patterns, forming a strict hierarchy. In addition to the level identification between the same groups, the power information and other information of different groups can also be clearly distinguished from each other. For example, the Japanese family crest shows the family information to which the individual belongs, while the European family crest is more of a multi-level presentation, which may include family, class, status and other information. In addition, both of them have a long history and culture and a well-structured and systematic emblem pattern. When later generations studied the totem emblem patterns in other regions, they invariably used the two as a reference for comparison. What are these coats of arms and coats of arms used as a basis for judging status and class? This is the goal of this study, and it is hoped that the final findings will serve as a reference for other researchers.

In this study, an associated AR English learning system (AES) was developed for elementary children. Different from a general AR English learning system, when learners scan the AR target object, AES will provide associated virtual learning materials with the target object, including vocabulary, phrase and example sentences. At the same time, all the operational processes of the learner will be recorded in database within coding scheme by the system. The aim of this research is exploring learners’ behavior differences through analyzed their behavior log considering the human factors with gender and prior knowledge. One thing worth noting is, according to the result of the analysis, we found that learners can get a better performance in class when they are learning with an associated AR English learning system than a general AR English learning system. In addition, through observe the behavior pattern associated graphs, we found that female learners lost the scan directions of AR learning target more often than male learners. However, the female learners learning with an AR target more carefully and detailed than male learners. According to the results of this study, it is shown that when learning English through AR technology, the gender difference is an important impact factor. Therefore, when teachers and AR developers want to use AR to assist English learning in the future, they must pay special attention to this. &nbsp

It has been demonstrated that the WS2 monolayer is an excellent template for AlN epitaxy at 400 °C low temperature. Low-temperature AlN thin films exhibit much superior crystalline quality than those grown directly on sapphire substrates. In addition to the small lattice mismatch between AlN and WS2 monolayer, we proposed a growth mechanism to explain the excellent van der Waal epitaxy by looking at the initial growth. This growth model reveals that transition metal dichalcogenides (TMDCs) are promising buffer layers for the deposition of III-nitrides but also suggests the novel combination of AlN and TMDCs in the research of future 2D field-effect transistors due to the extremely low leakage current of high-quality AlN films.

We report the demonstration of growing two-dimensional (2D) hexagonal-AlN ( h-AlN) on transition metal dichalcogenide (TMD) monolayers (MoS2, WS2, and WSe2) via van der Waals epitaxy by atomic layer deposition (ALD). Having atomically thin thickness and high theoretical carrier mobility, TMDs are attractive semiconductors for future dense and high-performance 3D IC, and 2D hexagonal boron nitride ( h-BN) as a gate dielectric is known to significantly improve TMD device performance. However, h-BN growth requires 1000 °C temperature that is not compatible with CMOS fabrication, and ALD deposition of any high-k 2D insulator on TMD continues to be an elusive goal. The epitaxial 2D layered h-AlN by low-temperature ALD is characterized by synchrotron-based grazing-incidence wide-angle x-ray scattering and high-resolution transmission electron microscopy. In addition, we demonstrate the feasibility of using layered h-AlN as an interfacial layer between WS2 and ALD HfO2. The significantly better uniformity and smoothness of HfO2 than that directly deposited on TMD are desirable characteristics for TMD transistor applications.

For the participants of the exercise, the improvement of physiological benefits is the highest degree of recognition, followed by social benefits, and psychological benefits again. In other words, the participants believe that the biggest benefit after the activity is the improvement of self-health fitness. Consumer demand for sports functionality will change with different environments. Because when exercising outdoors, it will cause changes in body muscle load and cardio-respiratory function due to the difference in road surface gradient. Therefore, in the design of sports training, in addition to the structure of the product itself must be in line with human factors engineering, and should also take into account the measurement values of various parts of the body related to riding. The average user tends to challenge the self and ignores the prevention of sports injuries, causing damage to the neck, lower back, knee or wrist. Therefore, how to build a machine that can provide better exercise through machine learning must be emphasized. How can you not create sports injuries as a basis for a product. Therefore, this study will provide a data source for future sports products in machine learning by using three different lower limb tread frequencies at a fixed intensity to observe the correlation between heart rate changes, muscle fatigue, and pedaling strength.
