Authors: Jun Yang, Qixiang Nie Guizhen He,
Published: August 2021

Since neither a single high-precision 3D coordinate laser point cloud nor a oblique image of high-precision spectral information can make the computer understand the data as human, in order to accurately and completely understand the object in the real world, in this paper, the fusion of the point cloud and the oblique image is studied for the understanding and application of the real object buildings by establishing a BIM model. Firstly, point cloud data and image data are acquired by different data acquisition methods. Laser point cloud and oblique image are fused by installation parameters so that geometric elements are consistent and benchmark is unified. Processing level is not limited to element level only, so as to ensure the integrity of information, and the fused mutual information remains consistent in scale, texture and direction. Secondly, under the condition of space-time synchronization, the relationship between point cloud and image in geometric space is established, and the alternating "energy transfer" is used for shape prediction and visual filling by matching under texture mapping constraints to enhance the semantic information of the 3D scene. Finally, a 3D building information model is established. Using the experimental results to track the whole life cycle (design, construction, operation) in real time saves the cost of building rework, reduces the building cycle, and improves the building accuracy. Especially based on BIM during Novel Coronavirus Pneumonia: analyze hospital space resource management and elastic function; construct medical unit model of infectious disease hospital; simulate and optimize medical process in infectious disease hospital; rapidly construct prefabricated infectious disease emergency hospital; simulate hospital infection path and dynamics; the auxiliary design and construction of infectious disease treatment in existing hospitals; The monitoring analysis and automatic control of hospital infection safety operation.

This paper analyzes the operation performance of Beibu Gulf airlines (low cost airline company) with data envelopment analysis CCR model in pre-COVID-19 pandemic period. Under the domestic vigorous promotion of tourism development and people's huge demand for travel, the airlines in mainland China continue rapid development, which accelerates the emergence of local airlines other than the four major airlines and leads to increasingly fierce operation competition in the civil aviation industry. Behind the competition among airlines, the operational performance of airlines can best reflect the company's development status. In this context, airlines should choose appropriate operational strategies to strengthen its competitiveness and operational capabilities. The DEA model is a mature input-output research tool, and there have been many studies related to operational performance of the aviation industry. By using Data Envelopment Analysis (DEA) solver software, the input and output indicators from 2017 to 2019 are analyzed. Preliminary results show that routes and oil price factors have not reached effective status. Beibu Gulf Airlines gradually shifts to low-cost mode, the faced challenges are as follows: 1. The competition among domestic low-cost airlines; 2. The current poor overall service quality of low-cost airlines as evaluated by customers; 3. How to arrange routes, flight, service strategy, etc. Airbus uses enhanced aviation systems for this series of aircraft to improve the overall reliability of the aircraft, reduce maintenance and spare parts costs, thus helping airlines greatly reduce maintenance costs, which is very beneficial to low-cost airlines. Based on this, this paper puts forward some suggestions, such as optimizing routes, developing feeder flights in second tier cities of popular destinations, controlling fuel costs, making low-cost aviation fuel reserves, reducing the weight of passengers' carry-on luggage or charging additional baggage charges.

Manufacturing Enterprise Executive Career Expectation and Enterprise Risk: Theoretical Path and Empirical Evidence
Authors: Yao Yi
Published: August 2021

This paper takes listed companies in Shanghai and Shenzhen stock markets as research samples to analyze and test the relationship between executive career expectation and enterprise risk. This paper argues that manufacturing enterprise executive career expectations have a dual impact on corporate risk, one is to increase corporate risk through investment effect, the other is to reduce corporate risk through reputation effect. The results show that, in the two effects, reputation effect plays a leading role, that is, the higher the career expectation of executives, the more attention they pay to the professional reputation they try to build. In order to protect their own reputation from damage, executives pay more attention to the risk management and internal control of enterprises, so as to reduce the risk of enterprises. This also shows that reputation has a "implicit" incentive effect on executives .This study provides a theoretical basis for enterprises to formulate "explicit" and "implicit" incentive contracts.

Authors: Et al. Changjin Liu,
Published: August 2021

With the increasing public’s energy consumption, the resident’s energy-saving behavior has been paid more attention by all walks of life. Therefore, it is important to find out what factors influence the public's energy-saving behavior. The paper constructs a conceptual model of Chinese rural residents' energy-saving behavior of habit adjustment based on behavioral reasoning theory. It examines the energy-saving behavior of habit adjustment of rural residents on the basis of investigation data from rural residents in China. We reach the following conclusions: environment values not only significantly influence global motives (including attitudes about saving energy, subjective norms, perceived behavioral control) but also via the reasons for behavior have indirectly influences to it, thereby influencing rural residents' energy-saving intentions. The reasons for behavior have an indirect impact on rural residents' energy-saving intentions via the global motives. The reasons for behavior also directly influence the rural residents' energy-saving intentions. The attitudes about saving energy, the subjective norms and the perceived behavioral control have indirectly positive impacts on rural residents' energy-saving behavior of habit adjustment via the energy-saving intentions. The Poyang Lake Ecological Zone has an important ecological protection function in China. Promoting rural residents in there to save energy can effectively protect the environment.

Under the background of "made in China 2025", China's logistics development ushered in new opportunities, which put forward newer and higher requirements for the transformation and upgrading of the logistics industry.The fourth party logistics enterprise is a supply chain integrator.At present, there is a kind of fourth party logistics enterprise based on tripartite cooperation and operation mode in China. That is, fourth party logistics enterprises combine transportation enterprises withinsurance companies, and meanwhile rely on logistics information platform to carry out safety management of freight vehicles. In fact,in the process of tripartite cooperation, there are many uncertain factors, which bring multiple risks to the fourth party logistics enterprises. This paper studies and analyzes the risks faced by the fourth party logistics enterprises, in order to determine the important risk factors, so as to provide decision-making reference for the fourth party logistics enterprises to avoid risks. Firstly, this paper identifies the specific risks in the environment, cooperation, finance and management of the tripartite cooperation model from the internal, external and partnership dimensions, and reveals the mechanism of the risks. Secondly, the analytic hie-rarchy process (AHP) is used to calculate the comprehensive weight of each risk index, and the fuzzy synthetic evaluation method is used to determine the probability of risk. Finally, the overall risk level of X Company is ob-tained by establishing an evaluation matrix and weighting calculation according to the membership relationship between the evaluation matrix and the index weight. The results show that: from the perspective of the dimension of risk importance, cooperation risk and financial risk have the highest risk weight in the second-level index; in the third-level index, the behavioral risk of transportation enterprise, working capital risk and insurance company have the highest risk weight, while the weight of natural risk and political risk is lower. In the dimension of risk generation probability, inter-industry competition risk, transportation enterprise behavior risk, insurance company behavior risk and working capital risk are in the higher probability.

Simulation System of Wheat Broad Width Intelligent Precision Seeding
Authors: Et al. Zheng Chao Lv
Published: August 2021

In order to overcome the deficiencies of miss-seeding and random seeding in the current ground wheel driven seeding,a set of intelligent control simulation system for wheat precision seeding was studied and built.The system adopts self-designed seeding apparatus and intelligent control method to complete broad width and precision seeding of wheat. The system uses keys to set parameters such as seeding rate, thousand-grain weight and seeding space, etc.According to the measured value of the operating speed of the planter by the encoder, the speed of the DC motor is dynamically adjusted by controlling the pulse width modulation (PWM) of the chip, so as to achieve the purpose of changing the operating speed of the seeder and keeping the seeding rate and seed spacing unchanged. The DC motor is poweredby tractor’s own battery to drive seeding, and all information is displayed on the LCD.The simulation test of the rotation speed measurement of the seeding shaft shows that there is only slighterror caused by vibration between the corresponding theoretical and actual rotation speeds of the seeding shaft for different operating speeds when the intelligent control system of wide planting of wheat is used for seeding, which can meet the requirements of precision seeding.
Measuring the Impacts of Roads Infrastructure on Manufacturing Location
Authors: Xianglin Xu Yong Wan,
Published: August 2021

Using a detailed dataset on manufacturing firms, this study analyses the link between roads infrastructure and manufacturing location in Heilongjiang province, China. The results show that the improvement in roads facilities has very limited impact on the agglomeration of economic activities in Heilongjiang province during the 2001-2013 period, but this impact has changed to be significantly positive during 2008-2013 period, which has seen greater concentration. The explanation for this finding could be that the local protectionism and failed market economy took place in Heilongjiang province more recently. We also try to differentiate this distributive effect of road infrastructures across manufacturing sectors. The empirical results show that the technology-intensive and labor-intensive firms show a greater preference for areas with better road networks, while the resource-oriented industries appear to be not attracted by better road infrastructure. Important policy implications emerge from our findings for transport planning, enabling manufacturing firms to benefit from agglomeration economies and regions to achieve sustainable economic growth.

The method of ultrasonic precise sealing based on efficiency’s feedback was used and the influence of micro energy director array’s distribution size on the quality of ultrasonic sealing was summarized through the observation on the rule of wetting behavior of micro energy director array.
Research on Technology and Application of Buried Faults Identification in Urban Underground Space
Authors: Et al. Hongzhao Li
Published: August 2021

With theurbanization rate's rising and three-dimensional expansion and development of urban, the identification of underground buried faults has become the key factor of earthquake risk in urban underground space and surface area. As a typical method of detecting blind faults in underground space, shallow seismic prospecting technology plays an important role in judging and avoiding potential risks such as underground faults in the process of urban expansion and site selection. In this paper, shallow seismic prospecting technology is adopted, and optimized processing technologies such as parameter test, tomographic correction, pre-stack denoising, fidelity and consistency processing, correction iteration, migration imaging, and time-depth relationship deduction are adopted. Underground faults are identified and interpreted in the studied urban area, and fault risk assessment is carried out based on fault characteristics, scale, distribution and overlying strata, thus providing suggestions for regional pattern and construction of urban planning.
