System dependence net is a formal model to explicitly represent program dependences in a concurrent program which consists of multiple procedures. It is useful for development and maintenance of concurrent programs, such as program slicing, testing, debugging, and complexity measuring. A system dependence net generator for Ada 95 was proposed and developed. It cannot be used for Ada 2005 programs because Ada 2005 has a lot of changes from Ada 95. There is no study about how to generate system dependence nets of Ada 2005 programs until now. This paper proposes a method to generate system dependence nets of Ada 2005 programs by improving already proposed method for Ada 95.
This paper deals with a control strategy for underactuated underwater vehicle moving in 6-degrees of freedom whose target is the tracking of a space trajectory. The control algorithms proposed build upon Lyapunov'...

How to define neighbors in the feature space is important to visualization. Neighbors based not only on physical attributes but also on the feature attributes will provides a criterion to reduce complexity. We compare several distance measure methods in vortex visualization. These methods include λ 2 distance, Δ distance, Q distance, Γ 2 distance and normalized Euclidean distance of physical data from dataset. We compare these distance measure methods on three kinds of data samples from some fluid dynamic data set. We aim to find a measure to determine feature neighbors in flow data.

In recent years, the rapid development of mobile network and device promotes the investigation of mobile thin client technology. Based on the surveys in this field, we found that the codec used in the thin client protocol should be able to provide efficient data compression (to reduce network bandwidth consumption), and operate with low computing complexity (to decrease response latency and thin client power consumption). In this paper, we proposed a hybrid remote display protocol for mobile thin client, together with the main results of performance study.

since lane information is needed for road security improvement in driver assistance system (DAS), first basic step for this system is extraction of road marking. This paper presents a method to detect and extract of road lines to use in intelligent transportation system (ITS). This method is based on Hough transform concluding of three main phase: preprocessing, segmentation, post processing. The advantage of this method is overcome of existence problems such as noise, clear of road marking. This algorithm is implemented on real road scenes in video sequences taken by stationary traffic cameras. Experimental results demonstrate high accuracy of proposed algorithm as compared with classic method.

In this paper, a defect-analysis on computation of concept similarity, sememe similarity and set similarity in previous methods was given first. Next, a dynamic concept decomposition is used to regulate the amount of semantic information in the various parts of concept, and optimized the similarity between concepts; Then, the paper solved the imbalance problem of element match in previous set similarity computation by proposing a new algorithm of set similarity computation from the global perspective of semantic similarity; Finally, by taking into account the depth of the least Common Node reasonably in sememe similarity computation, this paper improved distinction degree of sememe similarity computation. The results in comparative experiment showed that the algorithm proposed by this paper is more close to the manual evaluation.
