It has been proved that when the transmit power is sufficiently large distributed space time codes can achieve the maximal diversity order in a wireless relay network. In the previous works, space time codes used in a wireless relay network are limited on unitary space time codes or orthogonal (or quasi- orthogonal) space time codes. In this paper, we apply general multi-layer full-rate space time codes generated by algebraic extension into the wireless relay network. Moreover, the optimal power allocation and the Chernoff upper bound of the pair-wise error probability (PEP) based on the maximum-likelihood (ML) decoding are calculated. Based on this bound, two design criteria of the multi-layer full-rate space time codes are provided.

How to handle unexpected exceptions to improve the reliability of workflow system is facing a major problem. The traditional exception handling in workflow system stays in expected exceptions handling, it is lack of the handling of unexpected exceptions, and the main handling of unexpected exceptions relies on the intervention of human, which reduces the efficiency of the system and takes a lot of time. This paper put forward to a method to handle the unexpected exceptions automatically and in real time, when unexpected exceptions are happened, the method can choose a new process definition to replace the current process model automatically, through this method the normal execution of the process can be guaranteed.

The transport traffic in WDM optical networks are provided to the networks customers in the form of lightpath via virtual topology reconfiguration(VTR), thus the algorithm to perform such an VTR has crucial impact on the resource usage efficiency. This paper proposes the routing algorithm of the Virtual Topology Reconfiguration based on the Genetic Algorithm (VTR-GA) for static traffic in the IP/WDM optical networks and develops an integer linear programming (ILP) model to solve the VTR problem. The proposed algorithm procedure and key issues, including the coding, initial population, fitness, crossover and variation within such an algorithm, are addressed. Its effectiveness in the resource utility has been verified by comparing the results from the proposed algorithm with those of both running CPLEX under the small-size network and the heuristic algorithms used formerly on the NSFnet.

With the rapid development of China's economy and continuous improvement of informatization levels, E-Government should achieve the cooperative development with economy and society. E-Government involves many domains, such as national governance, political affairs, economy, information technology, management theory and laws and regulations, which is the cross-cutting field striding over social sciences and natural sciences. E-Government development is a dynamic process in the trend of society development. This article analyzes the existing questions of domestic and foreign E-Government researches, utilizes the complex system paradigm, and proposes that E-Government's implementation is a complex giant system. It's necessary to take the complex system methodology as the basis and constructs the theoretical models according to this.

Key establishment in wireless sensor networks is a challenging problem for the constrained energy, memory, and computational capabilities of the sensor nodes. In this paper, focusing on the management of encryption keys in Heterogeneous Wireless Sensor Networks(HWSN), We propose a novel distributed key management scheme based on Shamir secret sharing scheme and deployment knowledge (HSNKMS). In HSNKMS, the sensor nodes are divided into some group, inner group pairwise keys are setup by random key distribution scheme, and intergorup pairwise keys are established by Shamir secret sharing scheme. We describe the details of our algorithm and compare it with other proposed schemes. Comparison and theory analysis show that the proposed scheme outperforms lots of the existing key establishment schemes in terms of wireless sensor networks security and key connectivity.
