	Abstract:Categorical data clustering (CDC) and link clustering (LC) have been considered as separate research and application areas. The main focus of this paper is to investigate the commonalities between these two problems and the uses of these commonalities for the creation of new clustering algorithms for categorical data based on cross-fertilization between the two disjoint research fields. More precisely, we formally transform the CDC problem into an LC problem, and apply LC approach for clustering categorical data. Experimental results on real datasets show that LC based clustering method is competitive with existing CDC algorithms with respect to clustering accuracy.

	Abstract:The goal of this paper is to show that generalizing the notion of frequent patterns can be useful in extending association analysis to more complex higher order patterns. To that end, we describe a general framework for modeling a complex pattern based on evaluating the interestingness of its sub-patterns. A key goal of any framework is to allow people to more easily express, explore, and communicate ideas, and hence, we illustrate how our framework can be used to describe a variety of commonly used patterns, such as frequent patterns, frequent closed patterns, indirect association patterns, hub patterns and authority patterns. To further illustrate the usefulness of the framework, we also present two new kinds of patterns that derived from the framework: clique pattern and bi-clique pattern and illustrate their practical use.

	Abstract:n a compound channel, the intense momentum transfer on the vertical interface between main channel and flood plain, makes its conveyance capacity decrease. For steady, uniform and turbulent flow, two new concepts, transverse kinetic energy correction coefficient (TKECC) and kinetic energy loss rate (KELR), are put forward in the paper. By the analysis of mechanics of transverse kinetic energy loss, the expression of transverse kinetic energy loss is obtained. According to the mechanics analysis, the two new concepts can reflect the transverse kinetic energy loss intensity in a channel with complex cross section. In the meanwhile, a conclusion is drawn that TKECC is larger than 1 and KELR is larger than 0 in compound channels. By analyzing a large number of experimental data from Science and Engineering Research Council Flood Channel Facility (SERC-FCF), it is found that TKECC and KELR are both related to shapes of cross section and relative depth (Dr). For a given relative depth, kine

	Abstract:his paper aims at investigating the feasibility of optimizing supply chain performance by analyzing customer data using data mining techniques. In particular, it introduces the C2S system that performs this task. In C2S, the overall supply chain management performance is measured by end customer satisfaction. And the working sequences of C2S can be summarized as follows. Firstly, customers are segmented into different groups using clustering algorithm and actionable cluster-defining rules are derived for each cluster. Secondly, for each segment, the Customer Lifetime Value (CLV) is computed and Customer Requirements are acquired. According to the distinct customer requirements in different customer segments, the association mining approach is employed to find possible factors through whole supply chain that are relevant to these requirements, to help the decision maker in making feasible actions to satisfy customer requirements. Thereafter, we can define the supply chain performance o

	Abstract:he distribution of velocity is one of basic issues in river dynamics. Based on the experimental data measured by ADV in the flume of State Key Laboratory of Hydraulics (SKLH), this paper analyzed the vertical distribution of point velocity and the varying law of turbulence intensity for movable bed in an asymmetric compound channel. Above certain relative height, the streamwise point velocity follows the logarithmic distribution. Under the location, the velocity varies linearly approximately. For all discharges in experiments, the streamwise, lateral and vertical turbulence intensities bear the similarity. They increase with flow depth increasing. After they reach the maximum values, they decrease as flow depth increase. In the meantime, the bed configuration is measured for four discharges, respectively. During the course of width adjustment, the main channel deposits and its side slope and flood plain erode when clean water is supplied. By the analysis of the bed in stabilization, i

	Abstract:A self-consistent nonlinear theory is described for a cyclotron autoresonance maser (CARM) amplifier with outer-slotted coaxial waveguide is presented. Typical simulation results, by utilizing an electron beam with voltage of 90KVand current of 50A, indicate the possibility with peak power of 773 KW and a saturated gain of 49 dB. The influence of the axial velocity spread decreases the peak power, efficiency, and saturated gain. Simulation also shows that the efficiency of the outer-slotted-coaxial waveguide CARM amplifier may be increased from 17.17% to 23.87% by tapering the magnetic field.

	Abstract:We propose a suboptimal joint demodulation decoding (JDD) algorithm for multiple-input, multiple-output (MIMO) channels. Compared with the optimal JDD, our algorithm can decrease the computational complexity significantly in the large number of transmit antennas, thus offering favorable performance/complexity characteristics. Computer simulation results are provided to compare the performance of the optimal JDD, suboptimal JDD, and the conventional separable soft-input soft-output demodulation decoding (SSDD).

	Abstract:With the increasing popularity of the Internet, there is a growing demand for web-based education, which allows students to study and learn at their own pace over the Internet. However in order to improve the teaching quality, such systems should be able to adapt the teaching in accordance with individual students’ ability and progress. Focusing on this objective, this paper proposes a new method to construct group-wised courseware by mining both context and structure of the courseware to build personalized web tutor trees. To this end, the concept of web tutor units and the notion of similarity are presented. Five algorithms, including the Naive Algorithm for tutor concept tree and the Level-generate Algorithm to generate web tutor units of K+1 levels are proposed. Experimental results are presented to demonstrate the effectiveness of the new method.
