Compare to random testing, Adaptive random testing generates test cases evenly in the input domain so that it can detect the first failure of the program using fewer test cases. But It is found that adaptive random testing will be more inclined to generate test cases on the boundary in the input domain, which is called “Boundary Effect”. The “Boundary Effect” will affect the performance of the adaptive random testing in certain situations, such as in multi-dimensional input domain. This paper presents an effective way to solve the “Boundary Effect” of adaptive random testing in order to enhance the performance in high-dimensional input domain.

The method for constructing full-connected network learning community model was given after discussing collaborative learning theory. The teaching process of applying network learning community model to “Database Course Design” was introduced in detail. The practice proves that CSCL is effective in the teaching of “Database Course Design”. Finally some issues needing to be solved in CSCL were analyzed and summarized.

In peer-to-peer (P2P) networks, how to effective locate data on distributed hash tables is challenging and has attracted much research attention in recent years. Two measurements are usually considered when discussing the effective location of data items: the path length (the hop count for resolving a lookup request on the overlay network) and the latency (the actual time period between the issuing and completion of a lookup). In this paper, we propose a regional lookup algorithm based on super-node (Hierarchical DHT Algorithm) that routes data keys queries by region information and super-node, and keeps the finger tables on two directions to reduce the redundancy of finger tables in original Chord. The lookup process can be easily implemented by keeping only O (log2M) routing information with M regions in the Chord ring at each node. Results from theoretical analysis and simulations show that the improved lookup algorithm achieves higher lookup efficiency and scales well.

wireless sensor network are promising to be used in a wide range of applications, the need to effective save and retrieve the data will grow. Metadata, self-describing data about sensor nodes and sensing data, assist to the data exchange between different users and understand different capabilities provided by heterogeneous sensor networks. Metadata management in resource constrained sensor nodes is unfeasible. Meanwhile, the agent is suitable to the heterogeneous sensor network with its characteristics of self-organization, distributed and strong processing capability. So, to minimize the energy cost of sensor, prolong the lifetime of sensor network and meet the requirements of access to real-time data we propose a framework that store and collection metadata in mobile agent. The proposed approach can deal with complex metadata of heterogeneous sensor network and achieve better performance in communication costs and real time process.

The paper introduces a two-tier writing support tool that helps students at school in writing more coherent essays. At one tier, students enter their essays and submit it for further process. At the other tier, the tutor receives the segmented format of their essays. The software prepares an environment to tutors for annotating students' essays in terms of a specific kind of annotation. Based-on the annotation the software produces a tree-shape graph representative of discourse structure of essays and sends it to the respective student. By observing many trees of this kind, we hope students understand the concept of discourse and write more coherent essays as a result. In the software, a novel Discourse Structure Builder Engine that has been recently proposed by researchers constructs the Discourse Tree based on a set of optimized discourse cue rules. In this paper it has been also shown why the software effectively reaches its aim, having looked at known theories in the concept of writing.

Coordinated development degree of county socio-economic system analysis and prediction play an important role in urban agglomeration coordinated development and improve benefit of regional coordinated development in China. According to the county socio-economic system data which is large scale and imbalance, this paper presented a support vector machine model to predict coordinated development degree of county socio-economic system. The method was compared with artificial neural network, decision tree, logistic regression and naive Bayesian classifier regarding coordinated development degree of county socio-economic system prediction for Guanzhong urban agglomeration. It is found that the method has the best accuracy rate, hit rate, covering rate and lift coefficient, and provides an effective measurement for coordinated development degree of county socio-economic system classification and prediction.
