LDoS attacks are a new type of denial of service attacks put forward by Kuzmanovic. According to several experiments, it is very effective in degrading the normal TCP senders throughput. XCP is a feedback-based congestion control protocol; it supplies feedback which is acquired through the use of a congestion header on each sent packet from the network to the sender on the maximum rate for injecting data into the network. In this paper, we studied the TCP protocol with explicit congestion control and found it has some characteristic in defending LDoS attacks, which give us a new idea to prevent LDoS attacks.

This paper proposed a method for analyzing the static strength and dynamic behaviors of a three-stage gearing with given parameters by using FEM and the parametric optimization design of the gearing. The 3D FE model of the whole gearing is developed using unique 20 node brick elements. Then all loads are exerted on the FE model to check the static strength of the gearing. The dynamics model is established based on considering transmission error excitation and shaft compliance as main vibration-exciting facts. In order to improve the transmission performance and suppress noises and vibrations of the gearing, a structural parameter optimization method is proposed to minimize the total weight and noise level of the gearing through optimizing some main parameters of the gearing such as modules, tooth numbers and distances between axes. The optimization results are validated by simulation experiment.

Community structure is one of the important topological characteristics of many complex networks. Detecting communities from networks has been intensively investigated in recent years. In most previous methods for community detection, the overlapping property of communities, which exists common in many real-world networks, is ignored. By combining commute-time kernel based distance measure and fuzzy affinity propagation, we present a new community detection algorithm CDKFAP for overlapping communities. Based on a new proposed index measures the fuzziness of nodes, the algorithm can rank and extract overlapping nodes of communities. The applications to computer-generated networks and real-world networks demonstrate the effectiveness of our algorithm.

Following the constant development of the computer technology and network technology, Virtual Reality Technology has been widely used in the Network Virtual Show and other aspects. This design uses VRML and 3DSMAX as a development platform and uses a residential district as a virtual prototype to achieve Internal Scene Virtual Tour within a residential building in a certain residential area. According to the characteristics of the Network Virtual Reality, this paper mainly introduces the building of landscape model and the approach of the scene roaming realization. Using 3DSMAX's three-dimensional modeling and output function, the constructed three-dimensional scene is outputted as VRML file format. After that, the translated three-dimensional scene is imported into VRMLPAD for programming and debugging, and then inserting the point of view, program optimization and so on. Finally, this paper designs and implements the residential building's internal scene Virtual Tour. Virtual reality scene not only can help browser to understand the overall situation within the building from everywhere, but also can achieve the dynamic interactions with the user. It presents as three-dimensional model in front of the users and generates an immersive feeling for the browser. Therefore, the virtual tour program has good external display role and practical value.

The establishment of confined concrete strength is an important issue in fiber reinforced polymer (FRP)-confined concrete column. This paper explores the use of Radial Basis Function Neural Network(RBFNN) in predicting the confinedment efficiency of FRP-confined concrete. Based on 362 experimental datas, the RBFNN model with highly non-linear reflection relationship was found and tested by the experimental data. A comparison study between the RBFNN model and four well-known models is carried out, it was found that the RBFNN model could reasonably capture the underlying behavior of FRP-confined concrete and provide better results than other models. The sensitivity analysis of the influential factor is also discussed, it shows that RBFNN-based modeling is a practical method for predicting the confinement efficiency of FRP-confined concrete.
