Association rules tell us interesting relationships between different items in transaction database. But traditional association rule has two disadvantages. Firstly it assumes every two items have same significance in database, which is unreasonable in many real applications and usually leads to incorrect results. On the other hand, traditional association rule representation contains too much redundancy which makes it difficult to be mined and used. This paper addresses the problem of mining weighted concise association rules based on closed itemsets under weighted support-significant framework, in which each item with different significance is assigned different weight. Through exploiting specific technique, the proposed algorithm can mine all weighted concise association rules while duplicate weighted itemset search space is pruned. As illustrated in experiments, the proposed method leads to good results and achieves good performance.

A net monitor system used to real-time monitor the state of the Controller Area Network (CAN) bus was designed. In the system, two while loops compose a producer consumer pattern which is the main program structure. The producer loop responds user actions and the consumer loop handles commands and data. The functions of the system such as data trace, graphics display, signal selection, and write frame are compiled in corresponding child VIs. Users can call those functions by clicking corresponding switches. While messages are transmitted in the bus, the signals that we want to monitor are real-time shown in the system. In the experiment, another CAN card is used to imitate the CAN bus that send messages to the monitoring system. The results show that the system can real-time monitor the CAN bus.

How to construct Boolean functions with good cryptographic characteristics is an interesting and significant problem in cryptography. Based on the maximal linear orthomorphic permutations, a method is proposed in this paper to construct a large class of Boolean functions with optimal algebraic immunity. Moreover, we demonstrate that the Boolean functions construct by Wang are contained in ours. The Boolean functions constructed in this paper can be balanced. At the end, based on the examples, we also give two conjectures on the construction of Boolean functions with optimal algebraic immunity.

In Service Oriented Architecture (SOA), software is implemented through a series of services and the business processes composed of services which introduce potential security problems. These security problems appeared in SOA software applications usually lead information systems and their business processes to risks. Similar to traditional quality of service (QoS) attributes such as reliability and robustness, security is one of the most important attributes of software system. In this paper, the method for modeling and analyzing the security attributes of SOA software system is investigated. Firstly, the service oriented computing model for security analysis is constructed, which characterizes service computing paradigm and related security attributes, and can be used for establishing service oriented software security metric system. Secondly, the service attack path is analyzed based upon the service oriented computing model. Finally, the effectiveness of the model and the analysis method is validated through case studies.

Identifying accurately the parameters of power amplifier (PA) nonlinear model is essential in modeling and predistortion of PA. RLS (Recursive Least Square) is a common used algorithm in parameter identification. The proposed algorithm modifies the cost function of the conventional RLS by multiplying a weighting function. The simulation results verify that the modified algorithm has better normalized mean square error (NMSE) performance than the conventional RLS.

According to the theory of mathematical morphological, edge detection operators and characteristics of wood decay image, a multi-structure element multi-scale edge detection algorithm based on mathematical morphology is proposed. The image is filtered by an alternative-order morphological corrosion-expansion filter with a multi-scale element, and the edge information is obtained using multi-structure elements open-close operation. Canny operator is used to extract the edge of the decay image. Experimental results show that the proposed algorithm is insensitive to noise and is efficient in edge detection.
