Firstly, associative-sets-based collaborative filtering algorithm is proposed. During the process of personalized recommendation, some items evaluated by users are performed by accident, in other words, they have little correlation with users' real preferences. These irrelevant items are equal to noise data, and often interfere with the effectiveness of collaborative filtering. A personalized recommendation algorithm based on Associative Sets is proposed in this paper to solve this problem. It uses frequent it sets to get associative sets, and makes recommendations according to users' real preferences, so as to enhance the accuracy of recommending results. Test results show that the new algorithm is more accurate than the traditional. Secondly, a flexible E-Commerce recommendation system is built. Traditional recommendation system is a sole tool with only one recommendation model. In e-commerce environment, commodities are very rich, personal demands are diversification; E-Commerce systems in different occasions require different types of recommended strategies. For that, we analysis the recommendation system with flexible theory, and proposed a flexible e-commerce recommendation system. It maps the implementation and demand through strategy module, and the whole system would be design as standard parts to adapt to the change of the recommendation strategy. © (2014) Trans Tech Publications, Switzerland.

Water quality's monitoring centre software of wireless sensor network is designed through applying C#.net and SQL database technology. The monitoring and querying of sensor node data is realized through adopting C/S (Client/Server) pattern. Standard structured query language (SQL) and ADO.NET database access technology are adopted to realize the rapid operation and efficient management on database. Graphical interfaces could display the topology and node status of sensor network, as well as the real-time and history parameters collected by each sensor node and so on. The practice has proved that this software could satisfy the data collection, as well as monitoring and management requirements of wireless sensor network monitoring system. Source

In this paper, the adaptive iterative learning control (AILC) scheme is proposed for a class of nonlinear discrete-time systems with parametric uncertainties subject to second-order internal model. Using the second-order internal model, it is shown that the timeiteration-varying uncertainties can be divided into two parts: the known iteration-varying part and unknown time-varying part. Leastsquares algorithm-based AILC method is proposed to deal with non-repetitive parameters. Through rigorous proof, we show that the proposed AILC method can deal with random initial condition and iteration-varying reference trajectory, in the sequel achieving asymptotical convergence in the iteration domain. The effectiveness of proposed algorithm is verified by simulation example. Source
