For 3-d laser scanning point clouds of an expressway tunnel, a method of automatically extracting complete contours of cross-sections from them is proposed. By taking advantage of abundant normal vectors embedded in point clouds, this method can accurately compute the central axis of the tunnel and build...

For the demands of unit equipment management under the new situation, equipment management system model was constructed based on Internet of Things, building programs of equipment information management system was put forward based on the system. Information sensing device are combined with inside LAN,...

To investigate the dynamic response of shell structure under underwater shock wave load, a three-dimensional numerical model for the typical shell structure under underwater shock wave load was established based on Arbitrary Lagrangian Eulerian algorithm. The dynamic response, deformation and failure...

Al-Qur’an Education Park (TPQ) Zahrotul Jannah is an educational institution located in Sidoarjo which has a private Al-Qur’an learning program for all ages with the advantage of flexible time and place. The number of students studying at TPQ has not yet reached the expected target because they do not...

In this paper, we have investigated the efficiency of two valuation models, discounted cashflow method and residual income method respectively. To prove the reliability and accuracy of the result shown in this essay, we will take Australia and New Zealand Banking Group as an example. Through these two...

City tourism contains plentiful data information, but not all the information is interested by tourists. Relying on tourists' interests, this paper designs and develops city tourism interest geographic information data collection system. Take Zhengzhou urban sight spots as an example to collection data...

In recent years, China has paid more and more attention in multiple university matriculation institution, which encourages the appearance of Comprehensive Evaluated Matriculation. Meanwhile, educational equality has gotten increasing attention from Chinese people. On this premise, discuss the educational...

Since the popularization of colleges digitization, the traditional ideological and political education can not meet the needs of college students. It is urgent to carry out ideological and political education with the times by the means of computer network. It is necessary and urgent to carry out the...

All of the articles in this proceedings volume have been presented at The 2nd International Conference: Resilience by Technology and Design 2024 (RTD 2024) during 15-18 July 2024 in Ho Chi Minh City and Vinh Long, Vietnam. These articles have been peer reviewed by the members of the Scientific Committee...

In this study, out of the idea of historical development, in the context of the development of visual culture to build brand image design and visual relationship between interpretation and perception of enlightenment Chinese century-old brand image design development brought on this basis. Conclusion...

There is in general no big fluctuation in elevator safety in China, but there are still underlying problems in elevator safety guarantee, such as enterprises' excessive pursuit of profit, inefficient maintenance and weak social safety consciousness. Considering those problems, this paper suggested getting...

With the continuous improvement of people's living material, the quality of the whole people's sports quality has gradually been paid attention to, our country has experienced the Olympic boom, the national sports boom is still not diminished, the mass sports career development gradually increased. And...

In this paper, an adaptive control design and stability analysis for a class of uncertain systems with unknown models is carried out. In particular, the adaptive control effect analysis is carried out based on the assumption that the unknown system mode is estimated with the wrong mode information. Based...

A kind of uncertain nonlinear system with unknown bounded function is analyzed. And a kind of common integral control is used to cope with the unknown function by taking example of a first order system. And by using of Laypunov stability theorem, we find that the system is stable but the unknown parameter...

In this paper, glucose and RDX as raw material, alveolate graphene was synthesized by shock wave in the detonation chamber. The results of TEM, HRTEM, SEM and XRD showed that alveolate graphene was synthesized in the wall of the detonation chamber. The ratio of RDX and glucose was an important role for...

In recent years, networks based on the 802.11 standards have gained a prolific deployment. The reason for this massive acceptance of the technology by both home users and corporations is due to the “plug-and-play” nature of the technology and the mobility. The lack of physical containment due to the...

Radio frequency identification technology has characteristics of non-contact, flexible radiation direction, efficient speaking, reading and writing data, large information storage capacity, which has attracted many researchers to introduce library information management technology into the library in...

The emergence of the Internet led to a period, also brought a lot of convenience to people's life, and the wave of Internet online shopping has gradually become another mainstream network service. School students now do not have a very good handling for second-hand resources, which not only wastes the...

Careful research shows that Lin Yutang’s concept of four life periods is inspired from works of Shakespeare, and his creation of the fool can be a modified version of that of Shakespeare. It is clear that Shakespeare has an enormous influence on him, and humanism serves as the foundation for Lin Yutang...
