With the rapid development of the national economy and society, put forward higher requirements for power supply safety, as an important support system for power grid safety production and ...management, the development of communication network and the safe and reliable operation is very important. Therefore, in practical work, network construction, upgrading, maintenance and management are the quality of network requires the corresponding evaluation criteria and assessment, all kinds of simulation and analysis technology to use, analyze and evaluate the bearing business ability, so as to establish a reliable network system to improve and optimize business structure business capacity. The data collection, the report on the actual situation of communication and communication network management system using the application range of comprehensive simulation and service quality evaluation system of the status quo of data exchange technology and communication network. To lay the foundation for the establishment of integrated simulation and evaluation system.
This paper focuses on the research of all kinds of data in the power grid business system, and carries on the research of intelligent analysis technology. It focuses on breaking the technical ...difficulties of intelligent and efficient analysis and mining, distributed multi-stream real-time processing, developing large-scale stock data for power and high-frequency incremental data efficient analysis system prototype, for wide-area distributed multi-stream real-time computing, from the data quick access to valuable information to solve the problems in the grid business system to improve the overall business performance, to achieve support power Data real-time processing and other technology applications.
The extremely overdoped cuprates are generally considered to be Fermi liquid metals without exotic orders, whereas the underdoped cuprates harbor intertwined states. Contrary to this conventional ...wisdom, using Cu \(L_3\) edge and O \(K\) edge resonant x-ray scattering, we reveal a charge order (CO) in overdoped La\(_{2-x}\)Sr\(_x\)CuO\(_4\) (0.35 \(\leq\) x \(\leq\) 0.6) beyond the superconducting dome. This CO has a periodicity of \(\sim\) 6 lattice units with correlation lengths of \(\sim 3 - 20\) lattice units. It shows similar in-plane momentum and polarization dependence and dispersive excitations as the CO of underdoped cuprates, but its maximum intensity differs along the c-direction and persists up to 300 K. This CO cannot be explained by either the Fermi surface instability or the doped Hubbard model and its origin remains to be understood. Our results suggest that CO is prevailing in the overdoped metallic regime and superconductivity emerges out of the CO phase upon decreasing hole carriers.
