Research on the Impact of China's OFDI to RCEP Countries from the Perspective of Country Distance
Authors: Zhang Jing
Published: April 2023

The official implementation of RCEP has created opportunities and conditions for China's OFDI. This paper comprehensively analyzes the influencing factors of China's OFDI to RCEP countries based on three dimensions of country distance: geographical distance, economic distance and institutional distance. It is found that: the greater the gap between institutional distance and geographical distance between RCEP parties and China, the more China tends to make direct investment to them, and China's direct investment behavior to RCEP countries is not significantly influenced by economic distance. From the sub-regional regression results, the key factors and utilities affecting OFDI are different in the three regions of RCEP member countries. ASEAN countries, Australia and New Zealand are mainly influenced by a combination of economic distance and institutional distance, where institutional distance promotes our OFDI behavior, while economic distance plays a hindering role. China's OFDI to Japan and South Korea is mainly hindered by institutional distance, and OFDI in all three regions is not significantly influenced by geographical distance.

Analyze the innovative exploration of war history movies from "Eight Hundred"
Authors: Zhao Jian
Published: April 2023

War movies in the new era not only bear the box office, but also bear a nation's attitude towards history and its own cognition. The innovation of technology, the liberation of ideas and the increasing distance of time and space between the audience and history make the development of war films face new problems and challenges. More and more mainstream war movies still do not break the traditional mainstream war movies' plot conception, characterization and didactic meaning are too rigid. As one of the few successful war movies in recent years, Babai overturns the flat characters in traditional movies and uses imagistic symbols interspersed with each other, which is a major breakthrough. And in the plot of a large number of "black and white contrast" to the film invisibly added a bit of tragedy. At the end of the film, the image of the white horse and the rat will be displayed, and the artistic depth of the film will be raised abruptly. These new explorations in the film will undoubtedly become an important reference for future war films.

Authors: Xu Tianyi
Published: April 2023

The shortage of water resources has become an important factor restricting economic and social development, and optimizing the inter-basin water transfer project is the key to solve the shortage of water resources. The purpose of this paper is to study the optimal operation of inter-basin water transfer project based on multi-objective optimization method considering the uncertainty of hydrological forecast. In this paper, a multiple linear regression algorithm is proposed. Based on this study, the experimental results of optimal operation of interbasin water transfer projects based on the uncertainty of hydrological forecast are analyzed. The experimental results in this paper show that the overall change of the forecast optimal dispatch chart considering the uncertainty of hydrological forecast is similar to the traditional optimal dispatch chart, the difference is that it incorporates hydrological data into the forecast, so that the current available water can be more accurately grasped. Therefore, in the flood season, the division of the guaranteed output area and the increased output area is clearer and more reasonable. Moreover, the forecast optimization dispatching chart considering the uncertainty of hydrological forecast can effectively improve the calculation of guarantee rate, which is of great significance to solve the urban water supply problem.
WLSAN: Wavelet-Layer-Spatial Attention Network for Single Image Super Resolution
Authors: Peng Ruixin , Su Yuyang , Yu Bingxuan , Yang Chunyan
Published: April 2023

Single Image Super Resolution has been a hot topic in recent years, which has wide application prospects. Some recent works use attention in SR to capture the inter-channel and inter-spatial relationships of feature maps. How- ever, these works cannot focus on the image features at different frequency do- mains. At the same time, the loss function of some SR models will make the model more inclined to reconstruct the smooth part and cannot consider the de- tails in multiple directions of the image. To address these problems, we propose a Wavelet-Layer-Spatial Attention Network (WLSAN), which makes use of  both essential global context and local information to improve accuracy and visual quality. Specifically, the proposed WLSAN consists of wavelet attention to model inter-dependencies by decomposing the image signals and non-local attention, including channel-spatial-layers. Meanwhile, we combine L1 with improved Sobel Loss, which enhances the stability during training and constrains different aspects of the HR image generation. Extensive experiments demonstrate that the proposed WLSAN exceeds many classical methods and states of the arts.

Authors: Li Nian , Chen Zhuoyuan , Jian Yalei
Published: April 2023

With the increasing importance of conservation and identification of antiquities, there are numerous methods for the identification of antiquities. In order to realise the analysis and identification of the components of ancient glass objects, this paper establishes a random forest identification model based on the original data, random forest feature extraction and the maximum correlation minimum redundancy algorithm (mRMR), and compares and analyses its effectiveness on various datasets. The mrmr algorithm-based random forest discrimination model achieved a combined accuracy and ROC curve coverage area (AUC value) of 1 on the unweathered dataset, which was close to a perfect model with high confidence in predicting the discrimination results; while the AUC value of the repeatedly trained model was not stable enough on the weathered dataset. Thus, this paper proposes a mrmr-based random forest-based discrimination model, which achieves an optimal AUC value of 0.9393 when the number of decision trees is 30 and the maximum number of splits is 10.

Published: April 2023

The study of ancient glass, as an important branch of scientific and technological archaeology, is an important physical material for exploring the economic, technological and cultural exchanges between China and foreign countries on the Silk Road. It is of great significance for the study of the development of ancient societies and cultural exchanges between China and foreign countries. This paper focuses on the composition analysis and identification of ancient glass products, based on data mining and software analysis, giving the weathering pattern of glass surface, predicting the chemical composition content before weathering, as well as cluster analysis and correlation analysis of different categories of glass and their chemical composition. We also concluded that the composition of silica, potassium oxide and barium oxide in high potassium glass artifacts changed to a great extent before and after weathering, while the composition of silica and lead oxide in lead-barium glass artifacts changed to a great extent, and finally, we constructed a multiple linear regression model for prediction by the data of each chemical composition at the weathering point, and conducted F-test on the model to prove that the prediction models of silica, potassium oxide, barium oxide and lead oxide had a good performance. The F-test of the model proved the reasonableness of the prediction models for silica, potassium oxide, barium oxide, and lead oxide. It can be concluded that the glass type has an influence on the chemical composition of glass, so the glass can be divided into two categories of glass: high potassium and lead-barium, and then the chemical composition of these two categories of glass were analyzed separately by gray correlation analysis to obtain the top five correlation ranking of the chemical composition of each category of glass, and then the differences in the chemical composition of these two categories of glass were compared.

Authors: Gao Yueyang , Su Fengrui , Xiong Junjun
Published: April 2023

As one of the earliest human materials invented by mankind, glass products play a great role in the study of history. Because the ancient glass is easily affected by the buried environment, resulting in the weathering of the surface of the cultural relics, this paper classifies the cultural relics in order to better protect and study the ancient glass. In this paper, some data of weathered cultural relics are collected to establish a model for subclassification of cultural relics.This paper first conducted principal component analysis of two different types of glass and screened out different principal components of two types of glass. Then, according to the number of cluster categories (K value) obtained by the contour algorithm, combined with the obtained principal components, the cluster analysis is used to divide the subclasses, and the specific subclass division method and division results are obtained. The subclass characteristics are obtained by analyzing for each subclass data. For the established subclass classification, multiple cluster analysis was performed using changed K values to perform the sensitivity and rationality analysis of the model. The results show that the model established in this paper finds a good classification rule for some chemical substances of weathered cultural relics, gives a logical division method, and explores and compares the similarities and differences between different chemical components.

Localization and Navigation System for Indoor Mobile Robot
Authors: Liu Yanbaihui
Published: April 2023

Visually impaired people usually find it hard to travel independently in many public places such as airports and shopping malls due to the problems of obstacle avoidance and guidance to the desired location. Therefore, in the highly dynamic indoor environment, how to improve indoor navigation robot localization and navigation accuracy so that they guide the visually impaired well becomes a problem. One way is to use visual SLAM. However, typical visual SLAM either assumes a static environment, which may lead to less accurate results in dynamic environments or assumes that the targets are all dynamic and removes all the feature points above, sacrificing computational speed to a large extent with the available computational power. This paper seeks to explore marginal localization and navigation systems for indoor navigation robotics. The proposed system is designed to improve localization and navigation accuracy in highly dynamic environments by identifying and tracking potentially moving objects and using vector field histograms for local path planning and obstacle avoidance. The system has been tested on a public indoor RGB-D dataset, and the results show that the new system improves accuracy and robustness while reducing computation time in highly dynamic indoor scenes.

Although government has proposed well developed polices to rapidly handle emergencies and systematically organized recovery actions, failures of emergency relief, such as ineffective rescue, can significantly increase the post-hazard death rate. With the advance of artificial intelligence, the use of robots for disaster management applications is a new trend in managing and accessing natural disasters. Disaster response robotics is capable of assisting and replacing rescue teams working in dangerous scenarios, which not only alleviates labor-intensity but also reduces the potential risks associated with rescue personnel. Research on construction automation has advanced, but extensive development is required to reach fully autonomous construction in disaster management and post-disaster recovery. Instead, human robotics collaboration is promising and able to effectively alleviate the knowledge deficit and confusion. In the article, different functions of disaster response robotics are introduced, and technical challenges and future improvements are described.

With the increasing demand for energy, non-renewable resources such as coal and oil, which are the main sources of energy, are gradually depleted and have caused serious pollution to the environment. Therefore, the development and utilization of new energy has become a major research topic in today's society; wave energy, as a new energy source, is one of the most abundant energy sources in the ocean and has considerable application prospects. In this paper, the float and oscillator motion models are established by fitting the drape displacement and drape velocity, the longitudinal rocking angular displacement and longitudinal rocking angular velocity of the float and oscillator to the Runge-Kutta method and matlab toolbox. The particle swarm optimization algorithm is then used to determine the maximum output power of the system, and the optimal damping coefficient.
The Development and Application of Silver Nanowires as Flexible Transparent Electrodes
Authors: Li Yuhang
Published: April 2023

Throughout the past 100 years, the electronics industry has developed rapidly. Research in the field of electronics is becoming more and more thorough. As a transparent conductive oxide (TCO), indium tin oxide (ITO) has dominated the flexible transparent electrode market since 1970. However, due to its limited production, high cost, and inflexibility, these limitations hinder the further development of ITO, so this paper turns the attention to the substitutes of ITO materials, such as silver nanowire AgNW and carbon nanotube CNT graphene. Because AgNW has good synthesis scalability and reproducibility, they can be easily dispersed in solvents, which is related to low cost and low cost. It consumes fewer raw materials than ITO and has similar optoelectronic properties. The produced AgNW electrode has high electrical and thermal conductivity, high optical transparency, and flexibility, which attracts people’s attention. Therefore, this paper focuses on the preparation, performance improvement, future application, and development prospect of silver nanowire AgNW electrode.

The main raw material of glass is quartz sand, due to the high melting point of pure quartz sand, to reduce the melting temperature, it is necessary to add fluxes during refining. Different fluxes are added, and their main chemical composition is also different. To accurately classify high potassium glass and lead-barium glass, this paper establishes a K-means clustering model to classify glass types. High potassium glasses were classified into three subclasses by the content of iron oxide and barium oxide and lead barium glasses were classified into three subclasses by the content of magnesium oxide and barium oxide. Sensitivity analysis was performed on the model and the results remained significantly correlated.

The effects of fillers width and energy density of laser on weld morphology were studied. The mullite filler with the quality ratio of 70wt.% Al2O3-30wt.% SiO2 was determined as the initial fillers for the joining of Al2O3 liners according to the crystalline phase of Al2O3 liners. The transient multiple physical model of diode laser joining Al2O3 ceramic liners was built by Multiphysics COMSOL, and the coupling of temperature and stress field was carried out. The thermodynamic properties of the Al2O3 liners and fillers were analyzed and tested. Numerical results showed that the increase of fillers width would effectively reduce the thermal stress of the joint. With the increase of the energy density, the temperature and thermal stress of the seam zone increased gradually. With the increase of laser joining heat input, weld penetration increased slowly and then sharply. The experimental results indicated that the weld zone free from pores and macro cracks can be formed with the fillers width of 3mm, laser power of 700W and welding speed of 1mm/s.
