摘要：
As the ART2 neural network clustering occurs normalization in the data inputting mode by vector and nonlinear transformation pretreatment process is easy to be filtered as a substrate for an important, but a minor component of the noise, while there are still phenomenon of the drifting mode in the learning process due to the correction of the value of weight, this paper proposes an improved method of ART2 neural network. The improved method stores the amplitude information in the learning process, and it is considering the shortest distance of being inputted into the center of the cluster, increasing a threshold limit value for determining outliers at the same time and eliminating the influence of outliers of the clustering results. Finally, the clustering of data samples experimental results show that: the improved ART2 network can handle negative data, the four quadrants of data can be effectively clustered, the performance is superior to the traditional ART2 network.

摘要：
To deal with the issues like existing common data sparseness in weibo social network and the phenomena of cold start, this paper puts forward a two-stage clustering based on the recommendation algorithm GCCR. The algorithm firstly selects users’ focused nodes which have higher number, so as to extract a dense subset of sparse data, and by using the method of graph paper, similar concerned interested core clustering is formed to this dense subset. Then, it is extracted that weibo content features of seed clustering and the whole data set other users. Then the entire user group is clustered based on content similarity. Finally the clustering results are used in subject recommendation. Through clustering the two phases of dense data subset and the whole data set, the clustering effect of extreme sparse data sets are improved. At the same time, because of fuzziness of graph clustering, this thesis retains a certain diversity in the process of user interest clustering, so as to avoid convergence too fast when cold start. This method is verified through the real social network data, and the experimental results show that this algorithm can effectively solve the problems such as data sparseness and cold start phenomenon.

摘要：
Considering a small-scale fading environment in a dense random wireless network, we investigate the impact of the carrier-sensing threshold on the link performance under the premise of a fixed carrier-sensing range. At first, we assume a close transmitter-receiver distance and model the network nodes as a homogeneous Poisson point process (PPP). Then we present a simple analysis model of the conditional link success probability to establish a correlation between the interference capture and the link success. Subsequently, based on the assumption that the interference among proximity nodes mainly comes from the nearby nodes, we obtain the bounds of the carrier-sensing threshold through stochastic analysis and a simple adaptive algorithm to adjust the carrier-sensing threshold within its bounds is further presented. Numerical results show that the proposed method enables the pending transmitter to adjust the bounds of the carrier-sensing threshold adaptively when the channel path-loss exponent changes and the validity of the proposed adaptive algorithm is verified in the simulations.

摘要：
In this paper, we are concerned with the solvability for a class of nonlinear sequential fractional dynamical systems with damping infinite dimensional spaces, which involves fractional Riemann-Liouville derivatives. The solutions of the dynamical systems are obtained by utilizing the method of Laplace transform technique and are based on the formula of the Laplace transform of the Mittag-Leffler function in two parameters. Next, we present the existence and uniqueness of solutions for nonlinear sequential fractional dynamical systems with damping by using fixed point theorems under some appropriate conditions.

摘要：
Network failures always occur in Internet, such as a large number of packets loss and so on. To solve the problem, a steady inter-domain path selection algorithm is proposed. When a router receives route advertisement triggered by the failure, the algorithm use the heuristic routing selection algorithm to choose the most stable route of currently available route as the best route. Through the stable routing selection, routers can quickly identify valid stable route and eliminate invalid routing research and router consumption of continually updating and introducing route. Experimental result shows that this algorithm can not only greatly shorten BGP route convergence time but also effectively reduce the number of BGP route updated information during the convergence.
