This paper designs and implements a C-like language interpreter using C++ based on the idea of modularity. The whole system can be divided into three modules, namely, lexical analyzer, syntactic analyzer and evaluation of expression. During the design, token is being used. The design puts great emphasis towards code reusability and extensibility, which makes it easy to embed the code into other C++ programs. The final testing result shows that the implemented interpreter realizes almost all the interpretation functions of C-like language, including the interpretation of interface function call. It can also be used as script engine of games to control game logic through text, and games can be modified during running without recompiling the source code. Moreover, it has good portability. It can successfully run on different operating systems like Windows XP, MAC OS X 10.6.1, and iPhone OS 3.0.
本文基于模块化思想，用c++语言设计并实现了一个类C语言解释器。整个系统可分为三个模块，即词法分析器、句法分析器和表达式求值。在设计期间，使用令牌。该设计非常强调代码的可重用性和可扩展性，这使得将代码嵌入到其他c++程序中变得很容易。最终的测试结果表明，所实现的解释器几乎实现了类c语言的所有解释功能，包括接口函数调用的解释。它也可以作为游戏的脚本引擎，通过文本来控制游戏逻辑，并且可以在运行过程中修改游戏，而无需重新编译源代码。此外，它具有良好的可移植性。它可以在Windows XP、MAC OS X 10.6.1和iPhone OS 3.0等不同的操作系统上成功运行。

To solve the subjective and uncertainly about trust in e-commerce system, a new trust model based on multidimensional trust cloud is proposed, which is on the basis of the past research on cloud model. History evaluation data is regard as the quantitative universe of discourse, trust cloud of entities' property is based on the weighted backward generation cloud algorithm, so the history behavior of an entity can be reflected very well through three numerical characteristics of cloud model. The results of experiments show that the model proposed in the paper can reflect a seller's property more accurately and can provide a favorable reference for a buyer entity in e-commerce.

Hilbert Huang Transform (HHT), which is based on EMD (Empirical Mode Decomposition) and Hilbert transform method, is a new signal analysis method. It suits for analyzing the non-linear and non-stationary signals, such as EEG signal particularly. The traditional EMD method has the Mode Mixing problem. Therefore a new method basing on Ensemble Empirical Mode Decomposition (EEMD) for processing the signal has been approached in this paper. This method can effectively ensure the integrity of signal's mapping in the different regions through adding random white noise component into the original data, and overcome the mode mixing problem of traditional EMD decomposition.

Mobile ad hoc network especially follows multihopping mechanism for routing to make a path from source to destination. If we have a sound and solid routing path that would be efficient, reliable and adaptable to the different scenarios of network too by following the next hop mechanism and also should be the farthest node with in the cluster then we could achieve better performance by the network. This paper gives more emphasis on the same phenomenon by simulating the protocol EPSAR over ADOV (reactive) and DSDV (proactive) existing protocol and also elaborates the mobility issue. This paper also presents the couple of simulations of EPSAR over multiple network (i.e. grows in terms of number of node) and also examines the performance and the feasibility of EPSAR by considering the different network parameters i.e. Data Packet sent, Delivery Ratio and End-to-End Delay.

A Byzantine Fault Tolerant Algorithm suiting web services is proposed considering the features of web services. There are significant differences between the algorithm and the Castro and Liskov's well-known practical Byzantine fault tolerance method. First, we have to create replicas on both sides of communicating web services, while in CLBFT's method, replicas are created only on the server side. Second, due to the autonomous behavior of web services, we have to synchronize the timing of the receiving of messages among replicas. The I/O automata model of the algorithm is presented, and it's correctness is formally specified and verified.
