Fault simulation is an important part of power system dynamic simulation, fault models in fully dynamic simulation software of power system simulates all kinds of symmetric and asymmetric complex faults by fault branch admittance matrix. Handling multiple faults and random faults by admittance matrix...

In today's transmission and distribution system, large transformers are widely equipped with on-load tap changer (hereinafter referred to as OLTC) to ensure the voltage quality of the system and users. Due to the complex mechanical structure and high operation frequency, there are often abnormal situations...

For power system real-time data capacity is large, and the actual storage space is limited. This paper proposes a real-time data compression method based on wavelet transform. This method compress and decompress real-time data in power system through compactly supported orthonormal wavelet. The results...

This paper briefly introduced the technical features of real-time database and distributed database. This paper also introduced real-time database platform based on CORBA component technology, and real-time database isomerism cluster which is the core part of real-time database platform. Based on the...

In the age of internet of things, the storage and real-time processing requirements of massive amounts of real-time data generated by sensors, so that the traditional database or data processing architecture has been unable to deal with. Analyzing the processing characteristics of the real-time data...

Based on a new buffer layer, the characteristics of multiple proton implantations field stop IGBT ( MPI-FS-IGBT) were simulated and analyzed Different from the conventional field stop IGBT (FS-IGBT) which has an abrupt thin buffer layer and grade-doping field stop IGBT(GFS-IGBT) whose buffer layer was...

For reducing the injuries of pedestrians when the collision accidents between pedestrian and vehicle occur, the design of car front structure has been proposed based on pedestrian protection, the design scheme includes a mechanical cushion structure of car bumper and a mechanical bounce device of hood...

The ideal design of the bumper should take full advantage of the bumper plastic deformation to absorb most crash energy in automobile collisions. In the paper, the bumpers with different inner structure (circular cross section form and honeycomb cross section), different materials (Al alloy, structural...

Based on OpenGL and Google library we established the target model library and the canny operator is used for edge detection. Combined with D-S evidence theory and Pseudo-Zernike moments, the air target recognition algorithm based on information fusion is proposed. Pseudo-Zernike moments are invariant...

Through the statistic analysis of the accident data of Heilongjiang freeway from 2010 to 2014, it is concluded the regularities of distribution of the accidents on the Heilongjiang freeway, as well as the factors influencing the security of Heilongjiang freeway system. Then, the evaluation index of Heilongjiang...

Data sharing among organizations is a practical application problem. In 2015, T. Miyamoto, Y. Murakami and M. Kasahara proposed two inter-organization cryptographic schemes for secure communication among organizations. Firstly, we give a security analysis of their RSA-based inter-organization cryptographic...

Basing on scene analysis and VaR calculation, this paper discussed system architecture of scenario calculation and accurate data's importance of system model from the view of system theory. We also discussed several kinds of data errors and their processing methods to avoid the error of data. Then we...

In China's social security system, disabled people, as special social groups, are vulnerable groups. They should receive more attention from the society. Also, there should be a sound and reliable social security system to help and protect disabled people. In recent years, China's social security system...

The college-enterprise cooperation is an effective method to cultivate innovative and applied talents facing enterprises, achieving the transformation of student status to staff. In this model, the resources of college and enterprises could be exchanged more efficiently to maximize the mutual benefits,...

This paper uses Extended Model of Internet Commerce Adoption (eMICA model) to analyze the website construction of e-commerce of Shanghai A-level tourist attractions. In the light of eMICA model, this paper divides these websites into different stages in order to find out problems such as slow information...

In today's Internet era, information technology promotes the modernization of education. As college teachers should follow the trend of The Times and constantly improve their professional comprehensive quality. This includes not only the specialization of subjects, but also the specialization of education,...

With the National Tourism Bureau to establish Hainan as the first whole country tourism creation Province, Sanya as the central tourist city of Hainan has the opportunity to develop, Sanya should combine tourism information technology to create a smart tourism platform. The level of tourism product development...

The betrothal gift is a peculiar social phenomenon. The high bride price reveals the some culture. The article analyzed the betrothal gift from the theoretical perspective of social exchange. It is essentially a medium of marriage exchange. With the development of modernization, the price of it in rural...

In this paper, a kind of environmental three-dimensional parking equipment was designed, which was flexible, easy to assemble, disassembled and portable. As a result, the vertical and transverse movements of the parked vehicles were realized in need. Easy assembled and removable steel structure was used...

As an important work to ensure the safety of navigation, marine hydrographic survey is not only the initial and basic link for the construction of integrated navigation system, but also the important content to fulfill the relevant international convention and implement marine management. This paper...

At present, the ideological and political education of college students has received unprecedented attention. On the one hand, the ideological and political education of the students in privately-run higher learning institutions reflects the general rule of the ideological and political education of...

To investigate the effect of collision parameters (impact area of hood, vehicle velocity, walking speed of pedestrian, pedestrian gait and pedestrian orientation) on the dynamics response and injury of pedestrian thorax by combining the merits of Finite Element (FE) method and analytical method of Multi-body...

The docking technology of the subsea production system control module (SCM) is a key part of installation. If the docking accuracy is not reached, or poor stability when docking, the butt joint between the hydraulic joint and the electrical joint cannot be accomplished, may also make the subsea control...

Predicting fatigue life of composite materials is essential to increase reliability of manufacturing systems.
