Nowadays new peer to peer (P2P) traffic with dynamic port and encrypted technology makes the identification of P2P traffic become more and more difficult. As one of the optimal classifiers, support vector machine (SVM) has special advantages with avoiding local…

Using TVAR(Time Varying AR) model and adaptive notch filter is a new method for the non-stationary jammer suppression in DSSS(Direct Sequence Spread Spectrum). The performance of TVAR model for IF (Instantaneous Frequency) estimation will be affected by some factors such…

Efficient task scheduling mechanism can better meet the users’ QoS requirement, and achieve the load balancing in physical hosts, so the cluster system with high scalability and reliability can effectively improve the information utilization of the system, thereby enhance the…

Data mining technology has been widely used in various applications. Important information could be discoveried by data mining technology. In the education efficiency analysis, it is essential to use data mining technology to analyze histrical data. However, little work has…

In order to reduce the repeated construction between telecom operators and telecom facilities, improve the utilization rate of telecom infrastructure, the use efficiency of earth ,the sources of energy and the consumption of raw materials, the protection of the natural…

Regional coal gas outburst prevention has become the prerequisite of coal mining in the most China underground collieries. It touched on miners’ lives so closely, but especially lacked of digitalization due to the hostile working environment, sightless strata reserves, complicated…

To study on the characteristics of the vibration signals of coal and stone hitting the armor plate during caving, a hybrid algorithm based on first order forward difference and wavelet transform modulus-maxima method is presented which can be used in…

Power system deregulation and the shortage of energy sources have led to increased interests in distributed generators (DGs). The access of DGs to the distribution networks brings advantages as well as creates adverse influences, which is related to the type,…

500kV substation is especially important to the grid of our country, once it encounters lightning damage, the safety and reliability of the whole power system will be directly affected. As lightning intruding waves will cause overvoltage on electric equipments by…

Because of the truth that the earth resources become increasingly tense, Low-head bulb turbine group was relatively fast developed and constructed in a time.The number of its running on the various types of rivers has reached a certain degree.However,its main…
