The plan of step by step to the next generation regional network of JSOU based on IPv6 has been put forward based on the architecture of JSOU, the construction planning and the specific content has...
In this paper, the assignment performance problem in the process of the allocation resources has not been considered in the present most cloud computing data center, this paper proposes a new cloud computing resources allocation strategy, on the basis of cost model of the parallel task performance, using the improved Fuzzy Clustering Algorithm (CBFCM -- C Cost based Fuzzy Clustering Algorithm) to...
In this paper, We do some exploration and research in the fifth-generation intelligent distance education platform, and propose the architecture model of the intelligent distance education platform. We also present a complete text paper strategy which is consisted of defining attributes of Questions, the definition of parameters of test paper, and difficulty and discrimination of transformation algorithm...
Dynamic spectrum access policy is crucial in improving the performance of overlay cognitive radio networks. Most of the previous works on spectrum sensing and dynamic spectrum access consider the sensing effectiveness and spectrum utilization as the design criteria, while ignoring the energy related issues and QoS constraints. In this article, we propose a QoS provisioning energy saving dynamic access...
With the rotor's AC excitation characteristics, the double fed motor can realize free control of the rotational speed and the torque, so it has advantages on mitigating subsynchronous resonance (SSR). This paper proposes the method of using double fed motor for mitigating SSR for the first time. When double fed motor and generator are installed coaxially, the double fed motor can bring in damping...
This paper introduces folded DGS resonators to be used as building blocks of two-band band-pass filter. The transmission line with defected ground structure (DGS) can increase the equivalent capacitance and inductance of the transmission line and the dielectric constant. This character is useful for the design of miniaturization filter. The folded DGS resonator is then applied to design a multilayer...
Most of region grids which have a lot of wind resource are not usually strong and the voltage stability issues caused by the wind farms which are integrated into grid transmission line extremely pop out. Due to research the voltage stability, this paper gives a detailed design of DFIG based variable speed wind turbine model on Real Time Digital Simulator (RTDS) platform. To improve the stability and...
To describe clinical characteristics, treatment and outcome of cryptococcal meningitis in immunocompetent children. Immunocompetent children with cryptococcal meningitis who attended Changzheng Hospital between 1998 and 2007 were retrospectively reviewed. During the 10 years reviewed, 11 children with cryptococcal meningitis were admitted to Changzheng hospital and identified as immunocompetent. The...
As various information resource of education and teaching process, implementation and using the education resource is the nucleus of education information-based By the analysis to education resource management system, this text search according to the feasibility that OSS sets up resource management system, then Liferay can become the technique platform that sets up resource management portal; the...
The ferrite process has been used in the treatment of wastewater containing Nickel, Chromium, Zinc and Copper in this paper. The operation parameters of wastewater treatment were also studied. Based on the experiment, optimum condition in terms of pH and dosage of FeSO4 were obtained. The concentration of Nickel, total Chromium, Zinc and Copper were less than 1.0mg/L, 1.5mg/L, 2.0mg/L, and 0.5mg/L...
In this paper, the development background of electric vehicles and the research status of V2G technology are analyzed, the functions realized in the grid by electric vehicles as mobile distributed energy storage units are set forth, and the economic and technical advantages of which are pointed out. Based on this, analysis to the configuration of a system wherein electric vehicles are connected to...
Mature landfill leachate, containing high concentration of nitrogen, and low ratio of C/N, is difficult for biological treatment .In this paper, the leachate treatment of Jiangmen Landfill Site was studied. There is new requirement of the Standard for Pollution Control on the Landfill Site (GB16889-2008) of effluent TN concentration, after the processes of "SBR-Fenton-BAF". Two-stage BAF...
The Grounding system is very important for the normal operation of the power system and the safety of the equipment and human. The Grounding resistance is the main parameter of the Grounding system, and the measurement of which is the important reference for judging whether the Grounding system is efficient. The paper firstly introduces the concept of the grounding system and its alien frequencies...
As a multi-channel microwave remote sensing imaging radar system, polarimetric Synthetic Aperture Radar (SAR) enhances the information extraction ability for material scene in the observation area, in which the design and state monitoring for parameters play an important role in polarimetric SAR system and equipments management. This paper presents an analysis method for three typical polarimetric...
Eco-protection and poverty elimination has always been the unsolved problem in many countries and regions; especially for those less-developed ecological protected areas who have to pay extra attention to coordinating the relation between poverty elimination and ecological protection. Up to now, most of the traditional methods are short-term measures. Thus, we introduce the Regional Protection and...
Electroencephalography (EEG) is widely used in the field of neural engineering. EEG signals can describe the brain activities while the subjects with para/tetraplegia perform movement with their limbs. This paper reviews the research on the design of experiment, the different frequency bands of EEG signals and the data processing methods of EEG. According to the analysis of the previous studies, it...
